Conventional Mechanical Power Conversion and Transfer Systems of today are basically an assortment of “levers or simple machines”. All have various configurations and combinations with their input and output forces typically of a constant or a “uniform velocity ratio”.
Note: Because of the very difficult nature of the subject matter contained with the development of this invention, an extra bit of concentration by the builder or engineer is necessary to comprehend its principles. These principals mainly involve the “Theory of the Virtual Velocities”; Physics, Geometrics, Mathematics, Hydraulics, pneumatics, Applied Mechanics, and Electro Mechanics.
The present invention is a Power Conversion and Transfer System with an “above average efficiency”. The higher efficiency is provided because of the new systems unique configuration, which includes a movable fulcrum which provided a “changing mechanical advantage”. This combination provides a changing force velocity ratio of which a higher then average “variable output force” is made available for use.
The new inventions unique lever configuration is fashioned primarily within a “circle or disc lever”. It sits upright like a wheel, on a road. It has an Effort Force applied at the discs axis, with alternate left and right side output forces. This configuration of parts and forces allows the disc to rock and roll, reciprocate and or cycle to and fro on its support base. This new disc levers “variable mechanical advantage and its output force” arrangement provides the capacity to provide an “above average efficiency”.
Importantly, the Applied Effort Force is of a “Uniform Velocity”, and more importantly its Resistance output Force is provided to be of a “variable velocity”, which is declining during its motion or stroke cycle.
The average value of the “variable” output force, when defined mathematically, presents an “above average output force”. Its value is based on an output force supplied from a single disc unit. Importantly the above average work output is done in a certain “overall” distance and or time cycle. The higher then average output force when “compounded” with several disc units, (separate units in a common series force compounding configuration) can multiply and make available new highs in output efficiency.
In “applied mechanics and physics”, the quantity of work done is defined: If a force is not constant, then the work done equals the “average value” of the force, times the displacement of the particle parallel to the direction of the force. This work formula confirms the above average value of the new Disc Lever Units variable output force.
The present inventions above average efficiency, is provided because of a higher then average “variable output force” and is made available for use; efficiency, is defined as;
(where n=efficiency/w=work)
This variable output force starts out at a higher force and declines to a lower place where a comparable (in distance and or time cycle exists) conventional R output force is at. When equilibrium of the Effort and Resistance forces occurs motion of the disc stops, reverses direction, and continually repeats this declining output force process in to and fro cycles of motion and rest.
The Effort and Resistance forces are situated primarily at selected points on, about, or around the Disc.
Where the disc sits upright on its tangent support base is a very important part which is its “movable fulcrum arc”. This arc is a certain measured and selected segment of the discs circumference. This fulcrum arc provides a controlled changing mechanical advantage and changing moment arm ratio. With motion of the disc lever on its movable fulcrum, the Resistance moment arm actually “grows in length” while the Effort moment arm remains a constant (radius of the disc) length. This growing in length R moment arm provides for a controlled decline of the R output force. This being a 3rd class lever: the E force is applied between the fulcrum and the R force output. The longer the R moment arm the lesser the R force output, and this growing length provides a declining variable output force. This critically guided (positive accelerated velocity) variable R output force starts out at “a higher magnitude and declines” to a lower force magnitude where it meets equilibrium or a conventional state and the motion cycle stops.
By adding the high and the low force value of incremental readings, and dividing that number by the number of incremental readings taken. This provides its average output force. One must “compare this higher output force value” with that of a conventional lever's pinned fulcrum and its “constant output force”. This conventional lever has a constant lower output force. This conventional constant force compares with that output force of the new lever only when the new lever's work is done at the finish of its declining force stroke cycle. Both the conventional and new lever with its selected arc segment have the “same overall distance and or time cycle”. The new disc lever is providing an above average variable output force (because of its changing mechanical advantage) as compared with the conventional pinned fulcrum lever system, with its uniform force output.
Energy is simply the ability to do a “measured amount of work” in a certain distance and or time increment.
These principles of “work” are illustrated and demonstrated within the workings of this new invention.
The term variable velocity implies the ability to change the speed ratio by “small increments” over the entire range of control while the drive is under load. This also allows one to calculate its output force at any given point in its travel, or motion cycle.
The working principals of a crowbar as they apply to this new invention must be expounded upon here:
A crowbar is a bent lever, which separates the E and R forces and which have arms pivoting on, or bearing points on devices called “movable fulcrums” and resting this movable fulcrum on the floorboard or whatever as a support base. Did you ever notice that when using a crow bar to pull a nail or spike, that when the fulcrums contact point on the floor or support moves or rolls further away from the nail or work (the resistance arm is growing in length), that you must apply more Effort force to the effort arm of the crowbar (or hammer handle) to continue pulling the spike and having motion occur. This is similar to the workings of the growing R moment arm length within this new lever assembly.
In its motion cycle is a place where the new disc units overall E and R force traverse distance and or time segment (its virtual velocity ratio) matches that traverse distance and or time segment cycle of this said conventional lever system. This is the place in its travel cycle where equilibrium occurs and motion stops changes direction for another motion cycle.
The use of mechanical power conversion systems of previously known designs and configurations were mainly devised for the purpose of transferring power as input forces to output forces through various methods and apparatuses.
In this respect, the power conversion system according to the present invention substantially departs from the conventional concepts and designs of the prior art. In doing so it provides an apparatus primarily developed for the purpose of providing an above average efficiency in the transferring of power.
These critical specifications such as in the drawings, can be “transposed to any size circle or disc”. Also favored and “selected” are high efficiency fulcrum arc segments with large or small displays of motion, such as 16.226 degrees arcs to some with small displays of motion such as a 2 degree fulcrum arc which constitutes a selected roll traverse distance increment as it cycles along its support base.
This circle lever is illustrated herein as a 3rd class lever, where the Effort force is placed between the Resistance and the fulcrum. Also, the E and R force points of connection to the disc can be reversed for various needs and still provide an above average force output. These proportionately altered levers and force locations may affect the lever to be changed from a third class to a 1st or 2nd class lever assembly. These E and R forces can be critically and proportionately relocated and moved anywhere in, on, or about the disc and applied mechanically, hydraulically, electro-mechanically or other.
The only part of the disc that is needed is the critically selected “fulcrum arc segment”. The rest of the disc can be cut away. This cutting away is a method used in some modifications using custom proportionate “added on lever lengths” to the fulcrum arc piece and critically located in various advantageous places. This method provides and allows for a smaller more practical, “job rated” transmission case and or power conversion system.
The new disc lever unit can be modified for use in the raising of the efficiency of various machines. This includes all type automobile, trucks, locomotive, various hybrid vehicles, large and small power plants, boats, industrial equipment, aeronautical and space machines, electromechanical, power boosters, among many others etc.
The general purpose of the present invention is illustrated subsequently in greater detail. It is to provide a new and improved power conversion system and method, which has all the advantages of the prior art and none of the disadvantages.
With motion of the disc on its base, the movable fulcrum “changes the orientation” of the R output lines of force, which cause the R moment arm to grow in length (see
The term variable velocity implies the ability to change the speed ratio by “small increments” over the entire range of control while the drive is under load.
The disc lever for our example illustrations has a vertical diameter of 14.125 inches measured from the free tip ends of the ring gear or pinion teeth. This pinion has two sets of ring gear teeth, and a steel tire of the same diameter sandwiched in between them. These teeth are preferably of a smaller kind and are adapted to contact and mesh with the support base rack teeth. The narrow metal tire has a 14.125″ diameter is sandwiched between these teeth. This metal tire runs on a rail within the rack like a train wheel. This allows the pinion to rock and roll, and work along on its movable fulcrum arc in a linear path of travel on the support base rack. This combination of ring gear, steel tire and rail prevents sliding or translation of the pinion on the support base rack from occurring when this disc is under the stress of force in its travel cycle.
One modification for illustration as in
As the disc continues into its roll cycle it gains advantage of position which allows for a return trip or cycle in the opposite direction which also “makes available” the identical declining above average output force for use.
It is important, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope and themes of the present invention.
The main object of the present invention is to provide a power conversion system for very efficiently transferring power from controlled input effort forces of uniform velocity to new and useful output resistance forces of variable velocity.
By the use of combining together of several new disc lever units, the input and output E and R forces are compounded. This configuration utilizes “series compounding” using the principals and laws of the “compound lever”. It is necessary to compound these E and R forces hydraulically and or by the use of common hydraulic cylinders, multi-stage cylinders, various hydraulics, and or Electro-hydraulics, etc.
Note, that with series compounding, that the “variable R output force” of the 1st unit becomes a variable input E force applied at the axis of the next disc, etc. This is done hydraulically and applied proportionately to the input Effort force of the next unit etc., etc.
In general then, to compute the mechanical advantage of any compounding machine, first find the mechanical advantage of each separate element and then find the product of the separate advantages.
Note that in

A builder also can use other E and R force modifications in a similar manner as shown in

With reference now to the drawings, and in particular to
First provided is a horizontal support base 14. The support base is formed in a generally linear configuration. The base has a top surface 16. The top surface has equally spaced gear teeth 18 shown with a center support rail. In this manner, a rack with a center support rail is formed. A (disc) gear 22 is provided next. The disc has a central axis 24. The unneeded parts of the disc may be cut away, or it can be of “another shape modification”. Equally spaced and preferably small in size gear teeth 26 are provided. A steel tire 26A with the same diameter as the gear 22 is sandwiched between the teeth 26. This steel tire 26A supports the disc 22 and rolls on the rail 18A. The teeth give stability and effect the disc so as not to slide or translation occur while the disc is rolling (working) under the stress of force. Next is a first attachment member 48. This first attachment member 48 is formed as a reciprocating coupling which travels parallel to the base 14. One end of the first attachment member 48 is secured by a connecting pin and bushing to the axis of the pinion. The other end of the first attachment member is connected to the two way double ended hydraulic piston pump 48c (mounted to a frame not shown) which has automatic reverse flow control valves (not shown), and a reservoir at atmospheric pressure for spent hydraulic fluid is encased within an enclosure, also not shown. This 48c two way double ended hydraulic cylinder converts the uniform hydraulic forces provided by the live fluid from rotary piston pump 48a, to “measured to and fro motion cycles” of the disc on base 14. This “rotary” piston pump 48a is operatively connected and powered by input power member 46. 48b is a live oil supply line which transmits the (uniform Effort) forces from the rotary positive displacement piston pump 48a to the reciprocating two way double ended hydraulic cylinder 48c and of which reciprocates the first attachment member 48 and the disc in a to and fro fashion on base 14. Another oil line (not shown) returns the spent hydraulic oil from the reservoir to the rotary piston pump 48a. The first attachment member 48 also represents and lays out the trajectory of the E lines of force, which travel parallel to the base 14 and remain at 90 degrees to the start and finish constant length (the discs radius) E moments of force 22F and 22E.
Next provided is a second attachment member 50. This second attachment member is formed as a pivot able coupling. It is secured with a connecting pin and bushing to the “periphery” of the pinion at 36 and is movable between a first point A and a second point B (as shown in
Although only one selected working area along the base rack is needed and with the above operative embodiment, the circular gears (disc) fulcrum arc segment 24B may be modified in length by rolling to another “selected by test” working area along the base rack. A selected working area is a chosen fulcrum arc segment which treats the R output force to be variable, starting out at a higher than average R force and declining to where a conventional force is at and stopping, reversing and reciprocating to and fro. During this to and fro cycling process, one R force output is giving and losing force, while the other or opposite side point of R output is under no stress of force and is in its recycling process gaining the advantage of position, preparing for its power roll cycle in the opposite direction. A preferred fulcrum roll segment area as in
