This invention relates to torque/speed transmissions, specifically to improvements for a Cone Assembly that can be used to construct Continuously Variable Transmissions (CVT's).
The inventions of this disclosure are primarily for a “cone with one torque transmitting member” described in U.S. Pat. No. 8,628,439.
A “cone with one torque transmitting member” of U.S. Pat. No. 8,628,439 (which is referred to as a front pin belt cone assembly 520A) is described in column 90 line 64 to column 99 line 11; and shown in FIGS. 91A, 91 B, 92A, 92B, 93 to 101 of the Published Patent. A “cone with one torque transmitting member” is basically a cone that has a “torque transmitting member” that is rotatably fixed relative to the surface of its cone, but can slide axially relative to the surface of its cone. The “torque transmitting member” is used for torque transmission and can be made toothed. Preferably (although not absolutely necessary), a “cone with one torque transmitting member” also has a “non-torque transmitting member”, which is primarily used to maintain the alignment of the transmission belt of its cone and balance-out the centrifugal forces of the “torque transmitting member”. For the cone with one torque transmitting member of U.S. Pat. No. 8,628,439, which is referenced in the previous paragraph, the a “torque transmitting member” is labeled as “pin belt torque transmitting member 590” and the “non-torque transmitting member” is labeled as “pin belt non-torque transmitting member 690”.
An example of CVT that is constructed of out of two “cone with one torque transmitting member”, which are labeled as Cone 1A and Cone 1B, is shown in
Cones 1A and 1B are each a “cone with one torque transmitting member”. Cone 1A has a Torque Transmitting Member 1A-M1, Non-Torque Transmitting Member 1A-M2, and a Leveling Loop 1A-M3. Cone 1B has a Torque Transmitting Member 1B-M1, Non-torque Transmitting Member 1B-M2, and a Leveling Loop 1B-M3. Torque transmitting members 1A-M1 and 1B-M1 have teeth so that toothed torque transmission can be used, although friction torque transmitting members can also be used.
A leveling loop, such as Leveling Loop 1A-M3 and Leveling Loop 1B-M3, is a flexible loop with a tapered bottom surface that provides a level top resting surface for a transmission belt. It is recommended that each leveling loop is made out of a low friction flexible material that can expand and contract accordingly with the expansion and contraction of its cone; otherwise the CVT needs to be configured so that the leveling loops do not get in the way as the transmission ratio of their CVT is changed.
Tensioning Pulley 3 acts as a support pulley and tensioning pulley. Tensioning Pulley 3 and Support Pulley 4 are mounted so that they can freely move sideways in the horizontal direction. And Tensioning Pulley 3 is pushed upwards in the vertical direction so that it can maintain proper tension in Transmission Belt 2 for all operating conditions of the CVT.
In this disclosure, Cones, Cone Assemblies, Torque Transmitting Members, and Non-Torque Transmitting Members for “slightly modified commercially available” and “commercially available” Transmission Belts are described. Using a commercially available Transmission Belt instead of a custom Transmission Belt can significantly increase performance and reduce cost.
The Torque Transmitting Members and Non-Torque Transmitting Members described in the prior art (such as in U.S. Pat. No. 8,628,439) use a custom designed Transmission Belt in order to allow for the usage a Leveling Loop, which allows for a Level Resting Place for its Transmission Belt on the conical (sloped) surface of its cone.
The Torque Transmitting Members and Non-Torque Transmitting Members of prior art do not allow for the usage of a commercially available Transmission Belt, which is a Transmission Belt for which the teeth of said Transmission Belt are shaped below the belt of said Transmission Belt.
For the Torque Transmitting Members and Non-Torque Transmitting Members of prior art, a Leveling Loop has to be positioned beneath the bottom surface of its Transmission Belt in order to provide a Level Resting Place for its Transmission Belt.
A Leveling Loop of fixed length has to be able sit on the surface of its Cone on sections of its Cone where it needs to provide a Level Resting Place, and expand-out from the surface of its Cone as needed on sections of its Cone where it does not need to provide a Level Resting Place.
The Torque Transmitting Members of prior art allow for the usage of a Leveling Loop of fixed length; since their teeth, which are positioned on its side surfaces, will not prevent a Leveling Loop from expanding-out from the surface of its Cone. The teeth of the Torque Transmitting Member for a commercially available Transmission Belt will prevent a Leveling Loop from expanding-out from the surface of its cone. Also, a Leveling Loop that stretches as needed as the Transmission Diameter of its Cone is changed is undesirable, since this Leveling Loop will have a very small lateral stiffness, which is required in order to maintain the axial alignment and straightness of the Leveling Loop.
For a Torque Transmitting Member for a commercially available Transmission Belt, in order to provide a Level Resting Place for its Transmission Belt on the conical (sloped) surfaces of its Cone, which are surfaces that are not covered by its Torque Transmitting Member or its Non-Torque Transmitting Member, its Torque Transmitting Member and its Non-Torque Transmitting Member each have a Leveling Extension. The Leveling Extension of its Torque Transmitting Member can enter and exit its Non-Torque Transmitting Member as required; and the Leveling Extension of its Non-Torque Transmitting Member can enter and exit its Torque Transmitting Member as required.
For the reference numerals in this disclosure, the label M(number) after a reference numeral, where (number) is a number, such as M2 for example, is used to label different members of a part that is given one reference numeral but consist of more than one member. And the label S(number) after a reference numeral, where (number) is a number, such as S2 for example, is used to label the different shapes of a part that is given one reference numeral. Furthermore, same parts that are used in different location might have a different labeling letter after their reference numeral, or a different reference numeral altogether if this is helpful in describing the invention. If two parts have the same reference numeral then they are identical unless otherwise described.
In this section, a Torque Transmitting Chain Member, Non-Torque Transmitting Chain Member, and Leveling Loop for a Cone is described.
The Torque Transmitting Chain Member of this section is mainly formed by alternating Links 6A and 6B that are held together by Pins or Joiner Plates 5.
A Joiner Plate 5, which is shown in
A Link 6A is shown in
Tooth-to-Side Connector 6A-S3 and Tooth-to-Side Connector 6A-S4 are used to connect Tooth 6A-S1 to the sides of Link 6A, through Side Connector-Extension 6A-S5, and Side Connector-Extension 6A-S6 (see
Link 6A has two “narrow inner base portions”. One “narrow inner base portion” is formed by Tooth-to-Side Connector 6A-S3, and the other “narrow inner base portion” is for formed by Tooth-to-Side Connector 6A-S4 (see
Link 6B is basically identical to Link 6A except that it is wider. A Link 6B is shown in
Tooth-to-Side Connector 6B-S3 and Tooth-to-Side Connector 6B-S4 are used to connect Tooth 6B-S1 to the sides of Link 6B, through Side Connector-Extension 6B-S5, and Side Connector-Extension 6B-S6 (see
Link 6B has two “narrow inner base portions”. One “narrow inner base portion” is formed by Tooth-to-Side Connector 6B-S3, and the other “narrow inner base portion” is for formed by Tooth-to-Side Connector 6B-S4 (see
In order to attach the leading-end of a Torque Transmitting Chain Member of this section to a “cone with one torque transmitting member” that is referred to as a front pin belt cone assembly 520A in U.S. Pat. No. 8,628,439 (refer to column 90 line 64 to column 99 line 11; and FIGS. 91A, 91B, 92A, 92B, 93 to 101 of U.S. Pat. No. 8,628,439), a Leading End Torque Transmitting Chain Member 7 will be used.
And in order to secure the trailing-end of a Torque Transmitting Chain Member of this section to a “cone with one torque transmitting member”, a Trailing End Link 8 will be used. And in order to connect a Trailing End Slide (which is used to move and maintain the axial alignment of the trailing-end portion of a Torque Transmitting Chain Member) to a Torque Transmitting Chain Member, a Trailing End Joiner Plate 5B will be used.
Depending on the alternating-links arrangement of the Torque Transmitting Chain Member, in some configuration (such as Link 6B to Link 6A to Link 6B, instead of Link 6A to Link 6B to Link 6A for example), a Leading End Torque Transmitting Chain Member that is identical as described in the previous paragraph, except that its partial Link 6B portion is replaced with a partial Link 6A portion, has to be used.
Attachment Sleeves 7-S3 and 7-S4 are used to attach Leading End Torque Transmitting Chain Member 7 of a Torque Transmitting Chain Member to a torque transmitting member carriage 550A of a front pin belt cone assembly 520A of U.S. Pat. No. 8,628,439; using the same method that the sleeves of a leading end of a pin belt torque transmitting member 590 are attached to its torque transmitting member carriage 550A in U.S. Pat. No. 8,628,439 (refer to column 90 line 63 to column 91 line 48 of U.S. Pat. No. 8,628,439).
And b) unlike Link 6B, Trailing End Link 8 has a Slot Engagement Pin 8-S4, and the base of its tooth (which is labeled as Tooth 8-S3) is wider than the base of the tooth of Link 6B (which is labeled as Tooth 6B-S1) in order to better accommodate Slot Engagement Pin 8-S4.
Trailing End Link 8 is used as the trailing end link of its Torque Transmitting Chain Member, and Slot Engagement Pin 8-S4 is used to secure the trailing end of its Torque Transmitting Chain Member to its cone.
Depending on the alternating-links arrangement of the Torque Transmitting Chain Member, in some configuration (such as Link 6B to Link 6A to Link 6B, instead of Link 6A to Link 6B to Link 6A for example), a Trailing End Link 8 that is identical as described in the previous paragraph, except that its partial Link 6B portion is replaced with a partial Link 6A portion, has to be used.
Attachment Sleeve 5B-S1 is used to connect the trailing end portion of a Torque Transmitting Chain Member to a Trailing End Slide (which is used to move and maintain the axial alignment of the trailing-end-portion of a Torque Transmitting Chain Member) of its cone; using the same method that trailing plate sleeve 593-S1 of a pin belt torque transmitting member 590 is connected to a trailing end slide 565-S1 of its front pin belt cone assembly 520A of U.S. Pat. No. 8,628,439 (refer to column 92 line 54 to column 93 line 32 of U.S. Pat. No. 8,628,439).
A Torque Transmitting Chain Member should be designed so that its Slot Engagement Pin 8-S4 and its Attachment Sleeve 5B-S1 can slide in the same Trailing End Cut (the Trailing End Cuts for a cone are shown and labeled as trailing end cuts 540-S6 in FIG. 112B of U.S. Pat. No. 8,628,439), in a manner so that Slot Engagement Pin 8-S4 can engage with its Trailing End Cut surface that prevents its Torque Transmitting Chain Member from moving towards its Leading End Cut, so that Slot Engagement Pin 8-S4 can transfer torque in the direction that pulls from the Trailing End towards the Leading End of its cone; and preferably (but not necessarily) also prevents its Torque Transmitting Chain Member from moving away from its Leading End. If necessary, some play between Attachment Sleeve 5B-S1 and its Trailing End Cut is allowed. And if there are interferences between the fastener for Slot Engagement Pin 8-S4 and the fastener for Attachment Sleeve 5B-S1, then it is not necessary to use the fastener of Attachment Sleeve 5B-S1.
The Leading End Cuts for a cone are shown and labeled as leading end cuts 540-S1 in FIG. 112B of U.S. Pat. No. 8,628,439. The Leading End Cuts are used to insert the Attachment Sleeves of a Leading End Torque Transmitting Chain Member.
The proper location of Attachment Sleeve 5B-S1 relative to Slot Engagement Pin 8-S4, as well as the shape and size of all cuts on a cone can be determined through trial-and-error and experimentation (such as tracing for example).
The Joiner Plates 5 have Pins 5-S2 (see
In order to reduce friction, Washers 10, which should be made out of a low friction material, can be placed between all engaging side surfaces of two links, and between all engaging side surfaces of a link with a Joiner Plates 5 or Trailing End Joiner Plate 5B; however, this is not absolutely necessary, since the chain member can be used where it is submerged or coated in lubricants.
For Leading End Torque Transmitting Chain Member 7, the distance between Attachment Sleeves 7-S3 and 7-S4 can be reduced by using Joiner Plates 5A instead of Joiner Plates 5 in order to connect Leading End Torque Transmitting Chain Member 7 to its Link 6A (Joiner Plate 5A was described earlier and shown in
The Non-Torque Transmitting Chain Member of this section is mainly formed by alternating Links 12A and 12B that are held together by Pins or Joiner Plates 5.
A Link 12A is shown in
A Link 12A has a Side 12A-S2 and a Side 12-S3, which each have two holes 12A-S1. Side 12A-S2 and Side 12-S3 are connected by Base 12A-S6 through Side Connector-Extension 12A-S4 and Side Connector-Extension 12A-S5, which extend below Side 12A-S2 and Side 12-S3 and are narrower than said Sides in order to allow for sufficient bending of its Non-Torque Transmitting Chain Member
Base 12A-S6 of Link 12A is very narrow; this allows for a resting place for a section of a leveling loop. In addition, Base 12A-S6 is shaped so that the “cone surface resting base” of its leveling loop can slide over it during transmission ratio change.
A Link 12B is shown in
Furthermore, in order to prevent excessive vibration due to centrifugal forces, it is recommended that each link of a Torque Transmitting Chain Member has the same weight as the corresponding (oppositely positioned) link of its Non-Torque Transmitting Chain Member; so that the centrifugal forces of the Chain Members cancel each other out. This can be ensured through the selection of material or by adding weight increasing shapes to the links of the Non-Torque Transmitting Chain Member if necessary.
In order to attach the leading-end of a Non-Torque Transmitting Chain Member of this section to a “cone with one torque transmitting member” that is referred to as a front pin belt cone assembly 520A in U.S. Pat. No. 8,628,439 (refer to column 90 line 64 to column 99 line 11; and FIGS. 91A, 91 B, 92A, 92B, 93 to 101 of U.S. Pat. No. 8,628,439), a Leading End Non-Torque Transmitting Chain Member 13 will be used.
And in order to secure the trailing-end of a Non-Torque Transmitting Chain Member of this section to a “cone with one torque transmitting member”, a Trailing End Link 14 will be used.
And in order to connect a Trailing End Slide (which is used to move and maintain the axial alignment of the trailing-end portion of a Non-Torque Transmitting Chain Member) to a Torque Transmitting Chain Member, a Trailing End Joiner Plate 5B will be used.
Depending on the alternating-links arrangement of the Non-Torque Transmitting Chain Member, in some configuration (such as Link 12B to Link 12A to Link 12B, instead of Link 12A to Link 12B to Link 12A for example), a Leading End Non-Torque Transmitting Chain Member that is identical as described in the previous paragraph, except that its partial Link 12B portion is replaced with a partial Link 12A portion, has to be used.
Attachment Sleeves 13-S3 and 13-S4 are used to attach Leading End Non-Torque Transmitting Chain Member 13 of a Non-Torque Transmitting Chain Member to a torque transmitting member carriage 550A of a front pin belt cone assembly 520A of U.S. Pat. No. 8,628,439; using the same method that the sleeves of a leading end of a pin belt torque transmitting member 590 are attached to its torque transmitting member carriage 550A in U.S. Pat. No. 8,628,439 (refer to column 90 line 63 to column 91 line 48 of U.S. Pat. No. 8,628,439).
And b) unlike Link 12B, Trailing End Link 14 has a Slot Engagement Pin 14-S4 attached its base. The base of Trailing End Link 14 is labeled as Base 14-S3.
Trailing End Link 14 is used as the trailing end link of its Non-Torque Transmitting Chain Member, and Slot Engagement Pin 14-S4 is used to secure the trailing end of its Non-Torque Transmitting Chain Member to its cone.
Depending on the alternating-links arrangement of the Non-Torque Transmitting Chain Member, in some configuration (such as Link 6B to Link 6A to Link 6B, instead of Link 6A to Link 6B to Link 6A for example), a Trailing End Link 14 that is identical as described in the previous paragraph, except that its partial Link 12B portion is replaced with a partial Link 12A portion, has to be used.
Attachment Sleeve 5B-S1 is used to connect the trailing end portion of a Non-Torque Transmitting Chain Member to a Trailing End Slide (which is used to move and maintain the axial alignment of the trailing-end-portion of a Non-Torque Transmitting Chain Member) of its cone; using the same method that trailing plate sleeve 593-S1 of a pin belt torque transmitting member 590 is connected to a trailing end slide 565-S1 of its front pin belt cone assembly 520A of U.S. Pat. No. 8,628,439 (refer to column 92 line 54 to column 93 line 32 of U.S. Pat. No. 8,628,439).
A Non-Torque Transmitting Chain Member should be designed so that its Slot Engagement Pin 14-S4 and its Attachment Sleeve 5B-S1 can slide in the same Trailing End Cut (the Trailing End Cuts for a cone are shown and labeled as trailing end cuts 540-S6 in FIG. 112B of U.S. Pat. No. 8,628,439), in a manner so that Slot Engagement Pin 14-S4 can engage with its Trailing End Cut surface that prevents its Non-Torque Transmitting Chain Member from moving towards its Leading End Cut, so that Slot Engagement Pin 14-S4 can transfer torque in the direction that pulls from the Trailing End towards the Leading End of its cone; and preferably (but not necessarily) also prevents its Non-Torque Transmitting Chain Member from moving away from its Leading End. If necessary, some play between Attachment Sleeve 5B-S1 and its Trailing End Cut is allowed. And if there are interferences between the fastener for Slot Engagement Pin 14-S4 and the fastener for Attachment Sleeve 5B-S1, then it is not necessary to use the fastener of Attachment Sleeve 5B-S1. The Leading End Cuts for a cone are shown and labeled as leading end cuts 540-S1 in FIG. 112B of U.S. Pat. No. 8,628,439. The Leading End Cuts are used to insert the Attachment Sleeves of a Leading End Non-Torque Transmitting Chain Member.
The proper location of Attachment Sleeve 5B-S1 relative to Slot Engagement Pin 14-S4, as well as the shape and size of all cuts on a cone can be determined through trial-and-error and experimentation (such as tracing for example).
The Joiner Plates 5 have Pins 5-S2 (see
In order to reduce friction, Washers 10, which should be made out of a low friction material, can be placed between all engaging side surfaces of two links, and between all engaging side surfaces of a link with a Joiner Plates 5 or Trailing End Joiner Plate 5B; however, this is not absolutely necessary, since the chain member can be used where it is submerged or coated in lubricants.
For Leading End Non-Torque Transmitting Chain Member 13, the distance between Attachment Sleeves 13-S3 and 13-S4 can be reduced by using Joiner Plates 5A instead of Joiner Plates 5 in order to connect Leading End Non-Torque Transmitting Chain Member 13 to its Link 12A (Joiner Plate 5A was described earlier and shown in
The Leveling Loop of this section is shown in
In addition, Leveling Loop 16 also has Legs 16-S2 and Legs 16-S3 (see
Furthermore, the bases of each “Leg 16-S2 and Leg 16-S3” has a groove at/near its mid-width. The grooves of each “Leg 16-S2 and Leg 16-S3” and the bases of each “Leg 16-S2 and Leg 16-S3” are shaped so that their “Leg 16-S2 and Leg 16-S3” can slide-over the bases of their Non-Torque Transmitting Chain Member when the diameter of their cone is changed, and so that the bases of their Non-Torque Transmitting Chain Member can enter and exit said grooves.
Said grooves are necessary since for each 1-tooth diameter change of a cone, the “Leveling Loop 16 section” between a Torque Transmitting Chain Member and a Non-Torque Transmitting Chain Member only slides ½-tooth length towards or away from said Non-Torque Transmitting Chain Member. This is because there are two said “Leveling Loop 16 sections” oppositely position on said cone, which lengths each change by the amount of ½-tooth length for each 1-tooth diameter increase of said cone. Here said “Leveling Loop 16 sections” refers to the oppositely positioned spaces between a Torque Transmitting Chain Member and a Non-Torque Transmitting Chain Member, which change in length as the transmission diameter of their cone is changed.
For simplicity and the sake of introducing a concept, the items of this section (Torque Transmitting Chain Members, Non-Torque Transmitting Chain Members, and Leveling Loops) are all shown for a single-stranded chain only; but obviously with some slight modification (such as using two teeth instead of one tooth on a link for example), the items of this section can also be used with multi-stranded chains.
Torque Transmitting Member and Non-Torque Transmitting Member for Usage with a Slightly Modified Commercially Available Transmission Belt (
In this section, a Torque Transmitting Member and Non-Torque Transmitting Member for a Cone is described. The items of this section can be used with a slightly modified commercially available Transmission Belt, which is described in this section.
The Transmission Belt to be used with the items of this section is shown in
The Torque Transmitting Member of this section comprises of an elastomer segment that has reinforcement plates and reinforcement wires.
A reinforcement plate for the Torque Transmitting Member of this section, which is labeled as Reinforcement Plate 18, is shown in
Since the middle-section of the flat plate of Reinforcement Plate 18 has been cut-out, the flat plate of Reinforcement Plate 18 has two vertical sides (see
Reinforcement Plate 18 also has two Holes 18-S3; these holes are for the reinforcement wires of its Torque Transmitting Member; these holes should be located so that the bending-axis of its Torque Transmitting Member coincides with the bending-axis of its transmission belt.
In order to attach a Torque Transmitting Member of this section to a “cone with one torque transmitting member” that is referred to as a front pin belt cone assembly 520A in U.S. Pat. No. 8,628,439 (refer to column 90 line 64 to column 99 line 11; and FIGS. 91A, 91B, 92A, 92B, 93 to 101 of U.S. Pat. No. 8,628,439), a Leading End Reinforcement Plate 18A, a Trailing Sleeve Reinforcement Plate 18B, and a Trailing End Reinforcement Plate 18C can be used.
Attachment Sleeves 18A-S1 and 18A-S2 are used to attach the Leading End of a Torque Transmitting Member to a torque transmitting member carriage 550A of a front pin belt cone assembly 520A of U.S. Pat. No. 8,628,439; using the same method the sleeves of the leading end of a pin belt torque transmitting member 590 are attached to its torque transmitting member carriage 550A in U.S. Pat. No. 8,628,439 (refer to column 90 line 63 to column 91 line 48 of U.S. Pat. No. 8,628,439).
Attachment Sleeve 18B-S1 is used to connect its Torque Transmitting Member to its Trailing End Slide; using the same method used in U.S. Pat. No. 8,628,439 to connect the trailing end of a pin belt torque transmitting member 590 to its trailing end slide 565-S1 (see FIGS. 91A, 91B, 92A, 92B, 93 to 99). If necessary for alignment with Locking Ring Pin 18C-S3 in their Trailing End Cut (see paragraphs below for details), Attachment Sleeve 18B-S1 can be positioned behind or in-front of its Reinforcement Plate.
Trailing End Reinforcement Plate 18C also has two holes 18C-S2; these holes are for the reinforcement wires of its Torque Transmitting Member; these holes should be located so that the bending-axis of its Torque Transmitting Member coincides with the bending-axis of its transmission belt.
In addition, Trailing End Reinforcement Plate 18C also has a Locking Ring Pin 18C-S3. Locking Ring Pin 18C-S3 is used to secure the Trailing End of its Torque Transmitting Member to its cone by sliding a fastener such as a Dome Shaped Nut or a Ball Clamp (which is preferred) into Locking Ring Pin 18C-S3, and securing the fastener by inserting a Locking Ring into Locking Ring Groove 18C-S4 of Locking Ring Pin 18C-S3.
The Torque Transmitting Member using the Trailing Sleeve Reinforcement Plate (such as Trailing Sleeve Reinforcement Plate 18B, 18D or 18E) and Trailing End Reinforcement Plate 18C should be designed so that its Locking Ring Pin 18C-S3 and its “Attachment Sleeve of its Trailing Sleeve Reinforcement Plate” (such as Attachment Sleeve 18B-S1, 18D-S1 or 18E-S1) can slide in the same Trailing End Cut (the Trailing End Cuts for a cone are shown and labeled as trailing end cuts 540-S6 in FIG. 112B of U.S. Pat. No. 8,628,439), in a manner so that Locking Ring Pin 18C-S3 can engage with its Trailing End Cut surface that prevents its Torque Transmitting Member from moving towards its Leading End Cut, so that Locking Ring Pin 18C-S3 can transfer torque in the direction that pulls from the Trailing End towards the Leading End of its cone; and preferably (but not necessarily) also prevents its Torque Transmitting Member from moving away from its Leading End. If necessary, some play between the “Attachment Sleeve of the Trailing Sleeve Reinforcement Plate” and its Trailing End Cut is allowed. And if there are interferences between the fastener of Locking Ring Pin 18C-S3 and the fastener of the “Attachment Sleeve of the Trailing Sleeve Reinforcement Plate”, then it is not necessary to use the fastener for the “Attachment Sleeve of the Trailing Sleeve Reinforcement Plate”.
Although this is not preferred, but if it is too impractical to place Attachment Sleeve 18B-S1, 18D-S1 or 18E-S1 and Locking Ring Pin 18C-S3 in the same Trailing End Cut; then Locking Ring Pin 18C-S3 and its Trailing End Reinforcement Plate 18C do not have to be used. For this configuration, Attachment Sleeve 18B-S1, 18D-S1 or 18E-S1 should be secured to its cone using a fastener.
The Leading End Cuts for a cone are shown and labeled as leading end cuts 540-S1 in FIG. 112B of U.S. Pat. No. 8,628,439. For a said cone that uses a Torque Transmitting Member of this section, the Leading End Cuts are used to insert the Attachment Sleeves of a Leading End Reinforcement Plate.
The proper location of the “Attachment Sleeve of the Trailing Sleeve Reinforcement Plate” relative to Locking Ring Pin 18C-S3 as well as the shape and size of all cuts on a cone can be determined through trial-and-error and experimentation (such as tracing for example).
A Torque Transmitting Member of this section, which is labeled as Torque Transmitting Member 19, is shown in
When assembled on its cone, Leveling Extension 19-M2 is inserted into its Non-Torque Transmitting Member from which it will telescope in-and-out as the transmission diameter of its cone is changed. The previous sentence applies to a “Cone with One Torque Transmitting Member”, if a “Cone with Two Opposite Torque Transmitting Members” is used, then when assembled on its cone, Leveling Extension 19-M2 is inserted into the Torque Transmitting Member 19 that is positioned opposite of its Torque Transmitting Member 19, from which it will telescope in-and-out as the transmission diameter of its cone is changed.
Torque Transmitting Member Section 19-M1 comprises of a Leading End Reinforcement Plate 18A, a Trailing Sleeve Reinforcement Plate 18B, a Trailing End Reinforcement Plate 18C, and several Reinforcement Plates 18 that are joined together by two Reinforcement Wires 20 and encased by elastomer members as shown in
Between all teeth of the reinforcement plates, an elastomer Belt Resting Section 19-M1-S1 is fixed (see
It is recommended that Transmission Belt 17 has Teeth 17-S1 that can wedge into the teeth their Torque Transmitting Member Section 19-M1. Through this wedging action the teeth of Torque Transmitting Member Section 19-M1 will also support Transmission Belt 17; so that if desired, Belt Resting Section 19-M1-S1 can be omitted.
If Belt Resting Sections 19-M1-S1 prevent Teeth 17-S1 from properly wedging into the teeth of Torque Transmitting Member Section 19-M1, then Belt Resting Sections 19-M1-S1 should be redesigned or omitted. And if the Tooth Ends (such as Tooth Ends 18-S2 of Reinforcement Plate 18) of Torque Transmitting Member Section 19-M1 prevent Teeth 17-S1 from properly wedging into the teeth of Torque Transmitting Member Section 19-M1, then Tooth Ends 18-S2 should be redesigned, such as by removing the interfering surfaces for example.

The rear-end of Torque Transmitting Member Section 19-M1, which is shown as a sectional-view in
A rear-view of Leveling Extension 19-M2 is shown in
Leveling Extension 19-M2 has a Locking Ring Pin 19-M2-S1. Locking Ring Pin 19-M2-S1 is used to secure the rear-end of Leveling Extension 19-M2 to its cone using fasteners such as a Dome Shaped Nut or Ball Clamp (which is preferred) for example, and a Locking Ring. The shape and size of the cut for Locking Ring Pin 19-M2-S1 on its cone can be determined through trial-and-error and experimentation (such as tracing for example).
The Non-Torque Transmitting Member of this section has two separate elastomer side members that are joined at the leading end and trailing end (see
A Reinforcement Plate 21-M1 and a Reinforcement Plate 21-M2 are shown in
Reinforcement Plate 21-M1 also has a Rail Reinforcement 21-M1-S2, and Reinforcement Plate 21-M2 also has a Rail Reinforcement 21-M2-S2. Rail Reinforcements 21-M1-S2 and 21-M2-S2 are used as reinforcements for rails that are used to hold-in-place and guide the Leveling Extension that is inserted into its Non-Torque Transmitting Member and used to provide a resting place for Flanges 17-S2 of Transmission Belt 17 (see
In addition, in order to prevent excessive vibration due to centrifugal forces, it is recommended that each “Reinforcement Plate Pair” or “Reinforcement Plate” of a Non-Torque Transmitting Member has the same weight as the corresponding (oppositely positioned) Reinforcement Plate of its Torque Transmitting Member; so that the centrifugal forces of the Torque Transmitting Member and Non-Torque Transmitting Member cancel each other out. For this purpose Reinforcement Plate 21-M1 also has a Balancing Weight 21-M1-S3, and Reinforcement Plate 21-M2 also has a Balancing Weight 21-M2-S3. These Balancing Weights are not necessary if other means for balancing the weight of the Reinforcement Plates are used; such as through the selection of material, adjusting the thickness of the plates, etc.
Leading End Reinforcement Plate 21A is shown in
In addition, Attachment Sleeves are attached to the sides of Leading End Reinforcement Plate 21A; these Attachment Sleeves are labeled as Attachment Sleeves 21A-S2 and 21A-S3.
Attachment Sleeves 21A-S2 and 21A-S3 are used to attach the Leading End of a Non-Torque Transmitting Member to a torque transmitting member carriage 550A of a front pin belt cone assembly 520A of U.S. Pat. No. 8,628,439; using the same method the sleeves of the leading end of a pin belt torque transmitting member 590 are attached to its torque transmitting member carriage 550A in U.S. Pat. No. 8,628,439 (refer to column 90 line 63 to column 91 line 48 of U.S. Pat. No. 8,628,439).
Leading End Reinforcement Plate 21A also has two Holes 21A-S4; these holes are for the reinforcement wires of its Non-Torque Transmitting Member; these holes should be located so that the bending-axis of its Non-Torque Transmitting Member coincides with the bending-axis of its transmission belt.
Leading End Reinforcement Plate 21A also has two Rail Reinforcements 21A-S5. Rail Reinforcements 21A-S5 are used as reinforcements for rails that are used to hold-in-place and guide the Leveling Extension that is inserted into its Non-Torque Transmitting Member and used to provide a resting place for Flanges 17-S2 of Transmission Belt 17 (see
In addition, in order to prevent excessive vibration due to centrifugal forces, it is recommended that each “Reinforcement Plate Pair” or “Reinforcement Plate” of a Non-Torque Transmitting Member has the same weight as the corresponding (oppositely positioned) Reinforcement Plate of its Torque Transmitting Member; so that the centrifugal forces of the Torque Transmitting Member and Non-Torque Transmitting Member cancel each other out. For this purpose Leading End Reinforcement Plate 21A also has a Balancing Weights 21A-S6. These Balancing Weights are not necessary if other means for balancing the weight of the Reinforcement Plates are used; such as through the selection of material, adjusting the thickness of the plates, etc.
Attachment Sleeve 21B-S1 is used to connect its Non-Torque Transmitting Member to its Trailing End Slide; using the same method used in U.S. Pat. No. 8,628,439 to connect the trailing end of a pin belt torque transmitting member 590 to its trailing end slide 565-S1 (see FIGS. 91A, 91B, 92A, 92B, 93 to 99). If necessary for alignment with Locking Ring Pin 21C-S3 in their Trailing End Cut (see paragraphs below for details), Attachment Sleeve 21B-S1 can be positioned behind or in-front of its Reinforcement Plate; in the same manner as Attachment Sleeve 18B-S1 can be positioned behind or in-front of its Reinforcement Plate (see
Trailing End Reinforcement Plate 21C also has two holes 21C-S2; these holes are for the reinforcement wires of its Non-Torque Transmitting Member; these holes should be located so that the bending-axis of its Non-Torque Transmitting Member coincides with the bending-axis of its Transmission Belt 17.
In addition, Trailing End Reinforcement Plate 21C also has a Locking Ring Pin 21C-S3. Locking Ring Pin 21C-S3 is used to secure the Trailing End of its Non-Torque Transmitting Member to its cone by sliding a fastener such as a Dome Shaped Nut or a Ball Clamp (which is preferred) into Locking Ring Pin 21C-S3, and securing the fastener by inserting a Locking Ring into Locking Ring Groove 21C-S5 of Locking Ring Pin 21C-S3.
In order to prevent excessive vibration due to centrifugal forces, it is recommended that each “Reinforcement Plate Pair” or “Reinforcement Plate” of a Non-Torque Transmitting Member has the same weight as the corresponding (oppositely positioned) Reinforcement Plate of its Torque Transmitting Member; so that the centrifugal forces of the Torque Transmitting Member and Non-Torque Transmitting Member cancel each other out. For this purpose Trailing End Reinforcement Plate 21C also has a Balancing Weights 21C-S4. These Balancing Weights are not necessary if other means for balancing the weight of the Reinforcement Plates are used; such as through the selection of material, adjusting the thickness of the plates, etc.
Preferably, the Non-Torque Transmitting Member using Trailing Sleeve Reinforcement Plate 21B and Trailing End Reinforcement Plate 21C is designed so that its Locking Ring Pin 21C-S3 and its Attachment Sleeve 21B-S1 can slide in the same Trailing End Cut, in a manner so that Locking Ring Pin 21C-S3 can engage with its Trailing End Cut surface that prevents its Non-Torque Transmitting Member from moving towards its Leading End Cut, so that Locking Ring Pin 21C-S3 can transfer torque in the direction that pulls from the Trailing End towards the Leading End of its cone; and to a lesser preferable extent, also so as to prevents its Non-Torque Transmitting Member from moving away from its Leading End. If necessary, some play between Attachment Sleeve 21B-S1 and its Trailing End Cut is allowed. And if there are interferences between the fastener of Locking Ring Pin 21C-S3 and the fastener of Attachment Sleeve 21B-S1, then it is not necessary to use the fastener of Attachment Sleeve 21B-S1.
Although this is not preferred, but if it is too impractical to place Attachment Sleeve 21B-S1 and Locking Ring Pin 21C-S3 in the same Trailing End Cut; then Locking Ring Pin 21C-S3 and its Trailing End Reinforcement Plate 21C do not have to be used. For this configuration, Attachment Sleeve 21B-S1 should be secured to its cone using a fastener.
The proper location of Attachment Sleeve 21B-S1 relative to Locking Ring Pin 21C-S3 as well as the shape and size of all cuts on a cone can be determined through trial-and-error and experimentation (such as tracing for example).
A Non-Torque Transmitting Member of this section, which is labeled as Non-Torque Transmitting Member 22, is shown in
In its assembled state, Leveling Extension 22-M2 is inserted into its Torque Transmitting Member from which it will telescope in-and-out as the transmission diameter of its cone is changed. The purpose of Leveling Extension 22-M2 is to provide a base of for Teeth 17-S1 of Transmission Belt 17.
When assembled on its cone, Leveling Extension 22-M2 is inserted into its Torque Transmitting Member from which it will telescope in-and-out as the transmission diameter of its cone is changed.
The Non-Torque Transmitting Member of this section has two separate elastomer side members that are joined at the leading end and trailing end (see

Cone for usage with Torque Transmitting Member 19 and Non-Torque Transmitting Member 22 (
For Torque Transmitting Member 19, Cone 24 has the following cuts: a) Torque Transmitting Member Leading End Cut 24-A1, into which the sleeves of Leading End Reinforcement Plate 18A are inserted; b) Torque Transmitting Member Trailing End Cut 24-A2 (into which Locking Ring Pin 18C-S3 and Attachment Sleeve 18B-S1, 18D-S1, or 18E-S1 are inserted; and c) Torque Transmitting Member Leveling Extension Cut 24-A3, into which Locking Ring Pin 19-M2-S1 is inserted.
For Non-Torque Transmitting Member 22, Cone 24 (see
The cuts shown in
Torque Transmitting Member with Teeth have a Bottom Surface (Base) (
The Torque Transmitting Member 31 described in this section can be used with a Cone 38 described in the “Leveling Extension Raising Sheets” section below.
A Reinforcement Plate for a “Torque Transmitting Member for which its teeth have a bottom surface or Base” is shown in
Reinforcement Plate 25 is basically identical to Reinforcement Plate 18 of Torque Transmitting Member 19, except that it has a Base. Reinforcement Plate 25 is much preferred over Reinforcement Plate 18, since its Base will increase the strength of its tooth considerably.
The problem with having a Base is that because the Base has some thickness, “the top surface of its Leveling Extension (which is positioned beneath said Base)” and “the bottom surface of the tooth of its Reinforcement Plate” will have different heights. Since both surfaces are used to provide a resting base for the bottom surfaces of the teeth of their Transmission Belt, here the bottom surfaces of the teeth of their Transmission Belt will be resting on surfaces of different height. This problem is addressed in the “Leveling Extension Raising Sheets” and “Cone with Leveling Extension Raising Surfaces” sections below.
Reinforcement Plate 25 is shown in
Added to the flat plate are the following shapes: a Tooth 25-S6, Tooth Ends 25-S7, and a Base 25-S5. Tooth 25-S6 and Tooth Ends 25-S7 are shaped similarly to Tooth 18-S1 and Tooth Ends 18-S2 of Reinforcement Plate 18, and have the same functions. And Base 25-S5 is shaped beneath Tooth 25-S6 as shown; for increased strength and reduced weight Base 25-S5 has the shape of a tube.
Reinforcement Plate 25 can be used with a Transmission Belt that has side flanges, such as Transmission Belt 17; or if desired, Reinforcement Plate 25 can also be used with a regular commercially available Transmission Belt, such as a Transmission Belt 26, shown in
In order to attach a Torque Transmitting Member that uses Reinforcement Plates 25 to its cone, a Leading End Reinforcement Plate 25A (see
A “Torque Transmitting Member for which its teeth have a bottom surface (Base)” is shown in
Torque Transmitting Member Section 31-M1 comprises of a Leading End Reinforcement Plate 25A, a Trailing End Reinforcement Plate 25C, and several Reinforcement Plates 25 that are joined together by four Reinforcement Wires 32. Positioned in between two Reinforcement Plates are Longitudinal Elastomer Members 31-M1-S2 (see
Between all teeth of the Reinforcement Plates, a Lateral Elastomer Member 31-M1-S1 is fixed (see
The front-end of Leveling Extension 31-M2 is fixed/bonded to Trailing End Reinforcement Plate 25C (see
In order to help maintain the proper alignment/normality of a Reinforcement Plate, a Reinforcement Plate can have an Alignment Pin 33 (see
Furthermore, Torque Transmitting Member Section 31-M1 does not use a Trailing Sleeve Reinforcement Plate 25B. Since here in order to maintain the axial alignment of the rear-end of Torque Transmitting Member Section 31-M1, the axial alignment of Locking Ring Pin 25C-S3 is maintained by using a Telescope of the “Telescopes for maintaining the normality and the axial position of two oppositely positioned Locking Ring Pins” section below.
Non-Torque Transmitting Member that has a Bottom Surface for Teeth (Base) (
The Non-Torque Transmitting Member described in this section is to be used with Torque Transmitting Member 31 described in the previous section. In order to prevent excessive vibration due to centrifugal forces, it preferably has the same weight as its Torque Transmitting Member.
A Reinforcement Plate for a “Non-Torque Transmitting Member that has a bottom surface for teeth (Base)” is shown in
Reinforcement Plate 34 is basically identical to Reinforcement Plates 21-M1 and 21-M2 of Non-Torque Transmitting Member 22, except that it has a Base, which joins the two Reinforcement Plate Pairs (comprising of Reinforcement Plates 21-M1 and 21-M2) into one Reinforcement Plate.
The problem with having a Base is that because the Base has some thickness, “the top surface of its Leveling Extension (which is positioned beneath said Base)” and “the top surface of said Base” will have different heights. Since both surfaces are used to provide a resting base for the bottom surfaces of the teeth of their Transmission Belt, here the bottom surfaces of the teeth of their Transmission Belt will be resting on surfaces of different height. This problem is addressed in the “Leveling Extension Raising Sheets” and “Cone with Leveling Extension Raising Surfaces” sections below.
Reinforcement Plate 34 is shown in
Added to the flat plate are the following shapes: a Base 34-S5, and two Belt Flange Rests 34-S6. Base 25-S5 is shaped like lateral beam, which is used to support the teeth of its Transmission Belt; for increased strength and reduced weight Base 34-S5 has the shape of a tube. Belt Flange Rests 34-S6 are shaped on top of Base 34-S5 as shown; like Tooth Ends 25-S7, Belt Flange Rests 34-S6 can be used to provide a resting base for the flanges of a Transmission Belt that has flanges, such as Transmission Belt 17. If used with a Transmission Belt that does not have flanges, then Belt Flange Rests 34-S6 are not needed.
Reinforcement Plate 34 can be used with a Transmission Belt that has side flanges, such as Transmission Belt 17; or if desired, Reinforcement Plate 34 can also be used with a regular commercially available Transmission Belt, such as a Transmission Belt 26, shown in
In order to attach a Non-Torque Transmitting Member that uses Reinforcement Plates 34 to its cone, a Leading End Reinforcement Plate 34A (see
A “Non-Torque Transmitting Member that has a bottom surface for teeth (Base)” is shown in
Non-Torque Transmitting Member Section 35-M1 comprises of a Leading End Reinforcement Plate 34A, a Trailing End Reinforcement Plate 34C, and several Reinforcement Plates 34 that are joined together by four Reinforcement Wires 36. Positioned in between two Reinforcement Plates are Longitudinal Elastomer Members 35-M1-S2 (see
On top of the Bases of the Reinforcement Plates, a Non-Torque Transmitting Member Base Surface 35-M1-S1, which is made out an elastomer (flexible material), is fixed (see
The front-end of Leveling Extension 35-M2 is fixed/bonded to Trailing End Reinforcement Plate 34C (see
Furthermore, Non-Torque Transmitting Member Section 35-M1 does not use a Trailing Sleeve Reinforcement Plate 34B. Since here in order to maintain the axial alignment of the rear-end of Non-Torque Transmitting Member Section 35-M1, the axial alignment of Locking Ring Pin 34C-S3 (see
Elastomer Inserts for replacing Longitudinal Elastomer Members (
Described in this section are Elastomer Inserts that can be used to replace the Longitudinal Elastomer Members 31-M1-S2 of Torque Transmitting Member 31, and the Longitudinal Elastomer Members 35-M1-S2 of Non-Torque Transmitting Member 35.
An Elastomer Insert 37 is shown in
Also for Torque Transmitting Member 31 and Non-Torque Transmitting Member 35, it is preferable that the Reinforcement Wires are bonded to their Reinforcement Plates (such as by soldering, clamping, etc.), so that the tension from the Reinforcement Wires are transferred directly to their Reinforcement Plates.
In order to be able to use a Torque Transmitting Member 31 and a Non-Torque Transmitting Member 35, which each have a Base; two Leveling Extension Raising Sheets 39 can be used.
When Torque Transmitting Member 31 and a Non-Torque Transmitting Member 35 are assembled on Cone 38, the Leveling Extension Raising Sheets 39 are wrapping around Cone 38, in manner so that one Leveling Extension Raising Sheet 39 is resting on top of the Leveling Extension portion of its Torque Transmitting Member 31 and one Leveling Extension Raising Sheet 39 is resting on top of the Leveling Extension portion of its Non-Torque Transmitting Member 35, for all Transmission Diameters of their cone; so that the thickness of the Leveling Extension Raising Sheets 39 can compensate for the height of the Bases of Torque Transmitting Member 31 and Non-Torque Transmitting Member 35, so that the height of said Bases and the height of the surfaces of said Leveling Extension Raising Sheets 39 which are resting on said Leveling Extensions is equal or almost equal. This will provide level or almost level resting surfaces for the Teeth of their Transmission Belt. Leveling Extension Raising Sheets 39 should be able to flex so that they can rests level on top of their Leveling Extension portions.
For all Transmission Diameters, Leveling Extension Raising Sheets 39 should never cover their Torque Transmitting Member 31 or Non-Torque Transmitting Member 35, so that the Leveling Extension Raising Sheets 39 will never interfere with their Torque Transmitting Member 31 and Non-torque transmitting Member 35.
In order to attach Leveling Extension Raising Sheets 39 to Cone 38, Cone 38 has a Sheet Attachment Disk 40, and a Sheet Attachment Disk 41 fixed to it. To Sheet Attachment Disk 40, the right-ends of the Leveling Extension Raising Sheets 39 are attached by gluing, clamping, etc.; and to Sheet Attachment Disk 41, the left-ends of the Leveling Extension Raising Sheets 39 are attached by gluing, clamping, etc.
Cone with Leveling Extension Raising Surfaces (
For designs where on a level surface the “Transmission Belt resting surfaces” of the Torque Transmitting Member(s) and/or the Non-Torque Transmitting Member(s) are taller than the “Transmission Belt resting surfaces” of its/their Leveling Extension(s), than Leveling Extension Raising Surface(s) can be shaped on the surface of a cone. This allows for usage of Torque Transmitting Members and Non-Torque Transmitting Members that have a base. The Cone 42 described in this section can be used with Torque Transmitting Member(s) 43 and Non-Torque Transmitting Member 46 described in the section below.
Shown in
The height of Extension Raising Surfaces 42-S2 should be selected so that the “resting surfaces for the Transmission Belt Teeth” of its Torque Transmitting Member Section 43-M1 or its Non-Torque Transmitting Member Section 46-M1 (see section below), matches or almost matches “the height of the top-surface of Leveling Extensions 43-M2 and 46-M2 that are resting on Extension Raising Surfaces 42-S2”.
Each Extension Raising Surface 42-S2 has a Leveling Extension Ramp Clearance 42-S1 and a Member Width Clearance 42-S3.
Each Leveling Extension Ramp Clearance 42-S1 is located between the location where its Leveling Extension enters-and exits its Torque Transmitting Member 43 or its Non-Torque Transmitting Member 46 and the adjacent edge of its Extension Raising Surface 42-S2. Leveling Extension Ramp Clearance 42-S1 is for a Leveling Extension Ramp 44 described below.
Each Member Width Clearance 42-S3 is located between the Trailing End of its Torque Transmitting Member 43 or its Non-Torque Transmitting Member 46 and the adjacent edge of its Extension Raising Surfaces 42-S2. The purpose of Member Width Clearance 42-S3 is to ensure that the width of its Torque Transmitting Member 43 or its Non-Torque Transmitting Member 46 will not interfere with its Extension Raising Surfaces 42-S2.
Torque Transmitting Member and Non-Torque Transmitting Member for Cone with Leveling Extension Raising Surfaces (
Described in this section is a Torque Transmitting Member 43 and Non-Torque Transmitting Member 46 that can be used with a Cone 42 described in the previous section.
Torque Transmitting Member 43 is shown in
Regarding item a), Leveling Extension Ramp 44 (which is shown in
Regarding item d), Member Width Clearance Support 43-M2-S1 (which is shown in
Member Width Clearance Support 43-M2-S1 is useful because of the required Member Width Clearances 42-S3 (without a Member Width Clearance 42-S3, the tail-end of Torque Transmitting Member Section 43-M1 will interfere with the Extension Raising Surface 42-S2 adjacent to it).
Non-Torque Transmitting Member 46 is shown in
The purposes of modifications a) to d) of the previous paragraph are identical to the purposes of modifications a) to d) for Torque Transmitting Member 43; as such details regarding modifications a) to d) provided previously for Torque Transmitting Member 43, are also applicable for Non-Torque Transmitting Member 46.
In order to maintain the normality of two oppositely position Locking Ring Pins, at least one Slider Rod can be attached to one Locking Ring Pin; and at least one Insertion Sleeve, into which said Slider Rod will be inserted, can be attached to the oppositely position Locking Ring Pin. The Slider Rod and Insertion Sleeve should be positioned so they do not interfere with the Spline of their Cone as their Reinforcement Plates are slid from one end of their Cone to the other end of their Cone.
Per the previous paragraph,
If it is desired to fix the axial position of Insertion Sleeves 49 relative to Spline 51, then a Spline Sleeve 52 (see
Another method for maintaining the normality of two oppositely position Locking Ring Pins is to use two oppositely positioned telescopes that are each fixed to a Spline Sleeve 58. The axial position of Spline Sleeve 58 relative to the Spline to which it is inserted can be fixed in the same manner that the axial position of Spline Sleeve 52 is fixed relative to its Spline, which is through two sandwiching Shaft Collars 53 (see
Note, since the axial position of the “Trailing End of a Leveling Extension” is also maintained by its Torque Transmitting Member or Non-Torque Transmitting Member, Shaft Collars for maintaining the axial position of the Spline Sleeve for the “Trailing End of a Leveling Extension” is optional, but preferred to help ensure the straightness of its Torque Transmitting Member or Non-Torque Transmitting Member.
Also Offset Bar 62 and Top Member 54 of a Telescope can be fixed to its Locking Ring Pin through gluing, screwed-connection, etc.
A “Leading End Torque Transmitting Member Reinforcement Plate 63” is shown in
In order to increase the “rotational resistance” to supplement the “bending resistance” of Slider Base 64 to resist the moment due to the tension of its Transmission Belt, Slider Base 64 extends to the right and to the left of its “Reinforcement Plate 25”. Because of the taper of its Cone 68, increasing the length of Slider Base 64 will also increase the height difference between the lowest point and highest point of Slider Base 64, which in turn will increase the “rotational resistance” of Slider Base 64. A Reinforcement Tube 66 is used to strengthen the extension of Slider Base 64 to the left of “Reinforcement Plate 25”; and a Reinforcement Tube 65 is used to strengthen the extension of Slider Base 64 to the right of “Reinforcement Plate 25”.
In order to maintain the axial position of “Leading End Torque Transmitting Member Reinforcement Plate 63” relative to its Spline 70 (see
A “Leading End Non-Torque Transmitting Member Reinforcement Plate 67” is shown in
And like for “Leading End Torque Transmitting Member Reinforcement Plate 63”, in order to maintain the axial position of “Leading End Non-Torque Transmitting Member Reinforcement Plate 67” relative to its Spline 70 (see
The axial position of Spline Sleeve 69 relative to its Spline 70 can be fixed in the same manner that the axial position of Spline Sleeve 52 is fixed relative to its Spline, which is through two sandwiching Shaft Collars 53.
In order to minimize variation in the Transmission Diameter of a Cone due to variation in Transmission Belt tension, the CVT shown in
The CVT shown in
It is desired to minimize the variation in the Transmission Diameter of a Cone due to variation in Transmission Belt tension, so that tooth misalignment during re-engagement of a Torque Transmitting Member due to variation in Transmission Belt tension can be eliminated/minimized.
For the CVT shown in
For the CVT shown in
Transmission Diameter Compensating Mechanism 76 is shown in
If desired, Transmission Diameter Compensating Mechanism 76 can be replaced with a sensor that monitors and an actuator that controls the actual Transmission Diameter of a Cone. Transmission Diameter Compensating Mechanism 76 can also be used with a Cone that engages on the slack side of its transmission belt; but here depending on the configuration of the CVT, the threads might be angled in the opposite direction. For example, for a CVT where the tensioning pulley is positioned on the tense side, then if used, the Transmission Diameter Compensating Mechanism 76 should move its cone that engages on the slack of its transmission belt in the direction that will decrease its Transmission Diameter as the torque is increased, since here an increase in torque will reduce slack side tension and as such compression.
There are compression variation in the Transmission Belt, the Torque Transmitting Member, the Non-Torque Transmitting Member, and the Leveling Extensions at different Transmission Diameters; since for a Smaller Transmission Diameter the pressure of the Transmission Belt is dispersed over a smaller area than for a Larger Transmission Diameter.
Said compression variation can affect the Transmission Diameter of a cone. A larger compression will compress the Transmission Belt, the Torque Transmitting Member, the Non-Torque Transmitting Member, and the Leveling Extensions so that they will be positioned at a lower height, so as to reduce the Transmission Diameter. Here changing the transmission diameter of a Cone at fixed interval, as is ideal when there is no compression variation, can cause tooth misalignment during re-engagement of a Torque Transmitting Member.
In order to eliminate/minimize the “tooth misalignment during re-engagement” of the previous paragraph and other factors (such as whether the teeth of the Transmission Belt are resting on the Tooth Bases of their Non-Torque Transmitting Member or in between the Tooth Bases of their Non-Torque Transmitting Member), the transmission diameter of a Cone can be changed in variable intervals that are selected so as to minimize “tooth misalignment during re-engagement”. For example, when the transmission diameter of a cone is changed from 4 inched to 4.25 inches, the axial position of that cone is changed 0.25 inches; and when the transmission diameter of a cone is changed from 4.25 inched to 4.50 inches, the axial position of that cone is changed 0.1875 inches (instead of 0.25 inches); and when the transmission diameter of a cone is changed for 4.50 inched to 4.75 inches, the axial position of that cone is changed 0.125 inches (instead of 0.1875 inches); etc. The ideal profile for changing the axial position of a cone can be obtained experimentally or mathematically.
The preferred Torque Transmitting Member of the invention is Torque Transmitting Member 83, which is shown in
The preferred Non-Torque Transmitting Member of the invention is Non-Torque Transmitting Member 84, which is shown in
The preferred Cone Assembly of the invention is Cone Assembly 86, which is shown in
Attached to Cone Assembly 86 are a Torque Transmitting Member 83 and a Non-Torque Transmitting Member 84. The axial position relative to their Spline and the normality of the Trailing End Locking Ring Pins of Torque Transmitting Member 83, Non-Torque Transmitting Member 84, and their Leveling Extensions are each maintained using Telescopes, Slider Sleeves, and sandwiching Shaft Collars as described in the “Telescopes for maintaining the normality and the axial position of two oppositely positioned Locking Ring Pins” section.
“Leading End Torque Transmitting Member Reinforcement Plate 63” of Torque Transmitting Member 83, and “Leading End Non-Torque Transmitting Member Reinforcement Plate 67” of Non-Torque Transmitting Member 84 are each inserted into a Slotted Cut 68-S1 of its Cone 38A. And the axial position of “Leading End Torque Transmitting Member Reinforcement Plate 63” of Torque Transmitting Member 83 and “Leading End Non-Torque Transmitting Member Reinforcement Plate 67” of Non-Torque Transmitting Member 84, relative to their Spline, are maintained by Spline Sleeve 69 and sandwiching Shaft Collars as described in the “Leading End Torque Transmitting Member Reinforcement Plate 63” and “Leading End Non-Torque Transmitting Member Reinforcement Plate 67” section.
The Transmission Diameter of Cone Assembly 86 is changed by changing the axial position of its Cone 38A relative to its Spline, which also changes the axial position of Cone 38A relative to its Torque Transmitting Member 83 and Non-Torque Transmitting Member 84.
A Cone Assembly that transfers its main torque in the opposite direction of Cone Assembly 86 can be obtained by making a mirror image of Cone Assembly 86 and all its parts.
The second preferred Torque Transmitting Member of the invention is Torque Transmitting Member 87, which is shown in
The second preferred Non-Torque Transmitting Member of the invention is Non-Torque Transmitting Member 88, which is shown in
The second preferred Cone Assembly of the invention is Cone Assembly 90, which is shown in
Attached to Cone Assembly 90 are a Torque Transmitting Member 87 and a Non-Torque Transmitting Member 88. The axial position relative to their Spline and the normality of the Trailing End Locking Ring Pins of Torque Transmitting Member 87, Non-Torque Transmitting Member 88, and their Leveling Extensions are each maintained using Telescopes, Slider Sleeves, and sandwiching Shaft Collars as described in the “Telescopes for maintaining the normality and the axial position of two oppositely positioned Locking Ring Pins” section.
“Leading End Torque Transmitting Member Reinforcement Plate 63” of Torque Transmitting Member 87, and “Leading End Non-Torque Transmitting Member Reinforcement Plate 67” of Non-Torque Transmitting Member 88 are each inserted into a Slotted Cut 68-S1 of its Cone 42A. And the axial position of “Leading End Torque Transmitting Member Reinforcement Plate 63” of Torque Transmitting Member 83 and “Leading End Non-Torque Transmitting Member Reinforcement Plate 67” of Non-Torque Transmitting Member 84, relative to their Spline, are maintained by Spline Sleeve 69 and sandwiching Shaft Collars as described in the “Leading End Torque Transmitting Member Reinforcement Plate 63” and “Leading End Non-Torque Transmitting Member Reinforcement Plate 67” section.
The Transmission Diameter of Cone Assembly 90 is changed by changing the axial position of its Cone 42A relative to its Spline, which also changes the axial position of Cone 42A relative to its Torque Transmitting Member 87 and Non-Torque Transmitting Member 88.
A Cone Assembly that transfers its main torque in the opposite direction of Cone Assembly 90 can be obtained by making a mirror image of Cone Assembly 90 and all its parts.

Accordingly, the scope should be determined not by the embodiment(s) illustrated, but by the appended claims and their legal equivalents.
