It is generally known to provide a vehicle including a vehicle frame. It is generally known to provide a cab on frame type vehicle where a cab or body is produced and then installed on the separately produced and shipped vehicle frame. It is generally known to provide a body on frame structure for use with a pickup type vehicle.
A small overlap frontal crash test is designed to replicate what happens when only a relatively small portion of the front corner of a vehicle collides with another object like a vehicle, tree, utility pole or the like. To test vehicles for this type of performance, a small overlap frontal test has been developed. In the small overlap frontal test, a vehicle travels at 40 mph toward a 5-foot-tall rigid barrier and only the outer 25% of the vehicle width is impacted into the barrier—see
Even though such crush-zone and body (or cab) on frame type structures have long been known, there remains a continuing and significant need to provide added improved impact or crush performance. In particular, there long remains a continuing and significant need to provide additional improved impact performance by better reducing intrusion of the forward structures of the vehicle into the body or cab of the vehicle.
Referring in general to all of the Figures and in particular to
The vehicle frame 10 further includes a plurality of cross members for coupling the left and right side rails frame members 11 and 12, respectively. A first cross frame member 13 is located proximal the car forward direction and extends between the left-side frame rail 11 and the right-side frame rail 12. A second cross frame member 14 also extends between the left-side frame rail 11 in the right-side frame rail 12 at a location rearward of the cross frame member 13 and generally aligned with and proximal the wheels 2 of the vehicle 1. The vehicle frame 10 further includes a cross frame member 15 located rearward of the cross frame members 13 and 14 and generally aligned under a passenger compartment 5 of the cab 7 of the vehicle 1. The cross frame members 13, 14 and 15 extend longitudinally and the cross car direction and are coupled to the left-side frame rail 11 and the right-side frame rail 12 using any known or appropriate structure or process.
The vehicle frame 10 may further include left-side and right-side cab mount brackets 16 and 17, respectively, located proximal the second and third cross frame members 14 and 15, respectively, and coupled to the left-side and right-side side frame rails 11 and 12, respectively as best shown in
The vehicle frame 10 may further include left-side and right-side front blocker structures 100 and left-side and right-side rear blocker structures 200 coupled to the left side and right side frame members 11 and 12, respectively. The front blocker structure 100 is coupled to the side frame rail 11 at a location car forward and proximal the wheel 2. The left side vehicle frame rail 11 includes a first hole or passage 41 and the left side wall of the frame rail 11 includes a second hole or passage 51 in the right side wall of the frame 11. The front blocker structure 100 is located in and extends through the first passage 41 and the second passage 51. The front blocker structure 100 extends in a direction substantially aligned with the cross car direction (which is normal or perpendicular to the car forward direction) and outward from the frame rail 11 such that in a small offset frontal impact (where the impact is less than 25% of the vehicle width (see FIG. 1)), the front blocker structure 100 will be impacted before the wheel 2. Since the front blocker structure 100 is coupled to the left side vehicle frame rail 11, at least a portion of the energy of the small offset impact will be transferred to the left side frame rail 11 and therefore not transferred to the wheel 2. Since there is less energy transferred to the wheel 2, there will be less energy to move the wheel 2 toward the cab 6 of the vehicle 1 and therefore there will necessarily be less intrusion of the occupant compartment 5. Accordingly, it may be appreciated that the front blocker structure 100 may function to limit, and to control and guide the movement of the wheel 2 during an offset impact to the vehicle 1.
Referring more particularly known to
In one particular exemplary embodiment, the base member 110 of the front blocker structure 100 may be a generally tubular structure made from a high strength or ultrahigh strength steel using a stamping, forming and welding process or any other known and appropriate process for producing an object from such material. The base member 110 includes a first end 112 and a second end 113 and has a generally longitudinal extent there between defining a generally longitudinal axis. The base member 110 has a generally rectangularly shaped cross-section in a direction perpendicular to the longitudinal axis but may have other known and appropriate cross-section shapes. The base member 110 has a generally tubular shape including a cavity, chamber or passage 111 extending from the first end 112 to the second end 113. The base member 110 further includes a plurality of holes or passages 116 in its upper and lower surfaces and located proximal the end 112. The base member 110 is coupled by welding to the left side frame rail 11, as best shown in
The base member 110 of the front blocker structure 100 is welded to the holes 41 and 51 in the left side frame rail 11. The end 113 of the base member 110 may extend inboard of the left side frame rail 11 in the cross car direction a sufficient amount such that a MIG weld may be formed around the entire perimeter of the base member 110 and the opening hole 51 of the left side frame rail 11. Similarly, a MIG weld may be formed around at least a portion of (or alternatively the perimeter of the base 110 and the opening hole 41 of the left side frame rail 11 to securely couple the base member 110 of the front blocker structure 100 to the vehicle frame 10. Alternatively the weld may be of any known or appropriate type and may be formed around the entire perimeter of the openings 41 and 51. The base member 110 further includes an opening or hole or passage 115 in the upper surface and located between the first end 112 and the second end 113. The base member 110 further includes an opening or hole or passage 117 in the lower surface and located between the first end 112 and the second end 113 and the hole 117 is generally aligned and overlapping with the hole 115 to provide the ability for a structure (such as a mounting post of the cab 6) and assembly tools to pass through the components of the base member 110.
The front blocker structure 100 may further include the extension member 120 which may be coupled to the base member 110. In one particular exemplary embodiment according to the present disclosure, the extension member 120 may include a first or bottom portion 130 and a second or upper portion 140 as best shown in
The first or bottom portion 130 of the extension member 120 may be formed from a high strength or ultrahigh strength steel in a stamping procedure to include a first surface 131 having a generally planar extent and including a pair of depending side extensions 134 and 137. The width of the first surface 131 varies between the first end 122 and the second end 123 of the bottom portion 130. The second or upper portion 140 of the extension member 120 may also be formed from a high strength or ultrahigh strength steel in a stamping procedure to include a first surface 141 having a generally planar extent and including a pair of depending side extensions 144 and 147 having complementary shapes to the depending side extensions 134 and 137 of the bottom portion 130. Since the depending side portions 144 and 147 overlap with at least a portion of the depending side extensions 134 and 137 of the bottom portion 130, the first surface 131 of the bottom portion 130 generally has the matching shape to the first surface 141 of the upper portion 140 but may be slightly larger. Accordingly, the extension member 120 may be assembled by producing the bottom portion 130, the top portion 140 and coupling the portions together and then welding them using a MIG welding or similar process.
In one exemplary embodiment according to the present disclosure, the first surface 141 of the upper portion 140 may include a passage or opening 145 extending from the first end 122 and toward the second end 123. The opening 145 in the upper surface 141 of the upper or top portion 140 of the extension member 120 overlaps with at least a portion of the openings 115 and 117 in the upper and lower surfaces, respectively, of the base member 110. Accordingly, as may be best seen in
In one exemplary embodiment according to the present disclosure, the first surface 141 of the upper portion 140 may include holes 146 to be aligned with the holes 116 of the base member 110 when the first end 122 of the extension member 120 is received in the passage 111. Similarly, the first surface 131 of the bottom portion 130 may include holes 136 to be aligned with the holes 116 of the base member 110 and the holes 146 of the upper portion 140 when the first end 122 of the extension member 120 is received in the passage 111 of the base member 110. Accordingly, the extension member 120 may be coupled to the base member 110 using fasteners 160 which may be secured using nuts 161 which may be MIG or projection welded to the outer surface of the base member 110 once the fasteners 160 are inserted through the holes 146, 116 and 136 of the respective components and the nuts 161 are tightened. Accordingly, the design and construction of the front blocker structure 100 according to the present disclosure provides a bolt on extension member 120 to the base member 110 that may allow for more flexible assembly options.
In one exemplary embodiment according to the present disclosure, the front blocker structure 100 may further include a cab mounting pad, support, member or structure 170 coupled to the cab mount bracket 150. The cab mounting support 170 may include a passage 172 extending through the cab mounting support 170 and aligned with the hole 155 of the cab mounting bracket 150. The cab mounting support 170 may include any known or appropriate material and may preferably be made from an appropriately resilient yet sufficiently strong material for securely mounting the cab 6 to the vehicle frame 10 while also helping to properly insulate the occupant compartment 5 of the cab 6 from forces transferred form the vehicle frame 10.
In one particular exemplary embodiment according to the present disclosure, the extension member 120 may be coupled to the base member 110 at any appropriate time during the vehicle assembly process. In one exemplary embodiment, the extension member 120 may be coupled or assembled to the base member 110 during the manufacturing and assembly of the vehicle frame 10. In one particular exemplary embodiment according to the present disclosure, the extension member 120 may be separately produced from the production of the vehicle frame 10 and assembled to the vehicle frame 10 at any time prior to the cab 6 being assembled to the vehicle frame 10. More particularly, the extension member 120 may be assembled to the vehicle frame 10 after the vehicle frame 10 has been produced and transported to the vehicle assembly plant where the cab 6 may be assembled to the vehicle frame 10.
In one exemplary embodiment according to the present disclosure, the production of the vehicle frame 10 and the assembly of the vehicle 1 may include the process step of assembling the extension member 120 of the front blocker structure 100 to the base member 110 after the vehicle frame 10 has been transported to the assembly plant form the vehicle frame product plant or location. As indicated, the extension member 120 is coupled to the base member 110 using fasteners 160. In this manufacturing scenario, it is possible to produce the vehicle frames 10 including the base members 110 welded to the side frame rails 11 and 12 in a first vehicle frame manufacturing or production location and then ship the vehicle frames 10 to another location such as a vehicle assembly plant. The vehicle frames 10 may be stacked vertically and then the stacks of vehicle frames 10 may be loaded on a rail car or other carrier for shipping between locations. To reduce the costs of shipping it is desirable to have the stacks of vehicle frames 10 located as closely as possible together. In this particular exemplary embodiment, it should be appreciated that since vehicle frame 10 is shipped without the extension member 120 coupled to the base member 110 there will be no loss in the shipping density of the stacks of vehicle frames 10 on the rail car. Accordingly, in the present exemplary embodiment, the base members 110 are welded to the side frame members 11 and 12 during the assembly and production of the vehicle frame 10 and the base members 110 are sized such that the first end 112 of the base member 110 extends outboard of the side frame members 11 and 12 only a limited distance such that multiple vehicle frames 10 may be stacked for shipping to the vehicle assembly plant without any loss to the stacking density of the stacks of vehicle frames 10 as compared to the stacking density of the stacks of vehicle frames before the inclusion of the front blocker structure 100 according to the present disclosure. The same principles may also be applied to the other blocker structures of the exemplary embodiments of the present disclosure.
In one alternate exemplary embodiment according to the present disclosure, it may be noted that it is possible for both the base member 110 and the extension member 120 to be assembled to the vehicle frame 10 at the vehicle assembly plant after the vehicle frames 10 have been shipped to the vehicle assembly plant without any loss in the stacking density of the vehicle frames 10. In one alternate exemplary embodiment, the vehicle frame 10 may be produced with the multiple openings 41 and 51 in the side frame rails 11 and 12 and then the base members 110 may be coupled to the side frame rails 11 and 12 at the vehicle assembly plant. This alternate construction and method of production for the front blocker structure 100 has particular utility when a one-piece front blocker structure may be desired.
Referring now in particular to the alternate exemplary embodiment of the present disclosure of
The extension member 190 has a generally rectangular design and generally extends longitudinally and includes a longitudinal axis. The extension member 190 may include a first end 192 including an opening or passage 195 extending distally from the end 192 in a manner similar to the opening 145 in the end 122 of the extension member 120. The extension member 190 may further include holes 196 located distally from the end of the opening 195. The holes 196 may be distally located to be aligned with the holes 116 of the base member 110 when the end 192 of the extension member 190 is received in the passage 111 of the base member 110. The holes 196 may be located in sized appropriately to receive the fasteners 160 for coupling, or bolting on, the extension member 190 to the base member 110. The extension member 190 may include a car forward side 188 including an angle 182 from which and angled portion 185 extends and a car rearward side 189 including an angle 183 from which the angled portion 185 extends toward the end 191. The end 191 of the extension member 190 includes a lower portion 193 which is folded from the bottom surface of the extension member 190 and extends upward and an upper portion 194 which is folded from the top surface of the extension member 190 and extends downward as best shown in
While the vehicle 1 of the present disclosure is shown as including both a front blocker structure 100 and a rear blocker structure 200, it should be understood that it is possible to include either and/or both of the blocker structures on the vehicle as may be desired or appropriate for managing the crash forces and movement of the tire 3 during the offset frontal impact to the vehicle 1 to limit intrusion into the passenger compartment 5. Generally, the rear blocker structure 200 may be designed and constructed in a manner similar to the front blocker structure 100. The rear blocker structure 200 may be coupled to the left-hand and right-hand side frame rail members 11 and 12, respectively, of the vehicle frame 10. The left-hand frame rail member 11 may again include the opening 41 in which and end of the rear blocker structure 200 may be inserted and passed through the left-hand frame rail member 11. The end of the rear blocker structure 200 may be coupled to the left-hand frame rail 11 using a MIG welding process. Referring now in particular to
The rear blocker structure 200 may include a base member 210 which is shown in phantom lines in
The base member 210 and the extension member 230 each include holes (not shown) for receiving the bolts are fasteners 260 for coupling or bolting on the extension member 230 to the base member 210. Similar to the front blocker structure 100, the bolt on feature and structure of the rear blocker structure 200 allows the extension number 230 to be coupled to the base member 210 at the vehicle assembly plant and therefore allows for the continued use of the existing vehicle frame 10 transportation resources and maintaining the existing vehicle frame 10 shipping density. The use of the bolt on extension member 230 to the base member 210 further allows for continued use of the suspension alignment units and the existing frame and pedestal lines in the vehicle assembly plant. The rear blocker 200 may include the bolt on the clip 240 located in the passage 211 of the base member 210 as best shown in
The clip or support member 240 may be a generally planar sheet metal piece of material including a first formed end 241 and a second formed end 242 separated by a middle or bight portion 243. The ends 241 and 242 of the clip support 240 are formed to include generally circular or round-shaped passages 245 and 246, respectively, for providing a passage between the hole in the upper surface of the base member 210 and the hole in the lower surface of the base member 210 so that the shank of the fastener 260 may be easily and accurately passed through the passage 211 of the base member 210. In particular, the clip support 240 may be located in the passage 211 of the base member 210 and extend substantially between the upper surface and the lower surface of the passage 211 and may be welded in place using any known or appropriate weld type or process. The clip support 240 may provide additional support to the tubular structures of the base member 210 and the extension member 230 to allow the fasteners 260 to be torqued sufficiently tight without impairment to the members 210 and 230, respectively, and their connection. It is contemplated that the clip support 240 may be used with any of the blocker structures 100, 180, 200 and 300 of the present disclosure.
The bolt on front and rear blocker structures 100 and 200 respectively provide many advantages including the ability to design and implement a more optimal and tunable design by providing ability to select different material thicknesses for the base members 110 and 210 from the extension members 120 and 230, respectively.
In one exemplary embodiment of the present disclosure as best shown in
In one exemplary embodiment of the present disclosure it is understood that any of the features of the various blocker structures 100, 180, 200 and 300 may be used with any of the other blocker structures. In one specific example, it may be possible to use the extension member 120 of the blocker structure 100 and include a tire deflation device 310 therein. Additionally, it is expressly contemplated by the present disclosure that it may be possible for the tire deflation device 310 to be incorporated in the rear blocker structure 200 such that the tire 3 of the wheel 2 will not be deflated by the tire deflation device 310 until the frontal impact causes the front blocker structure 100 or 180 or 300 to move car rearward until it impacts the wheel 2 and moves it into engagement with the rear blocker structure 200. It is expressly contemplated by the present disclosure that any and all such combinations and substitutions of parts is possible. In another specific example, it is expressly contemplated that the clip 240 of the rear blocker structure 200 may be used for coupling any extension member to any base member. For example, the clip 240 may be welded in the passage 111 of the base member 110 for bolting on the extension member 120 using the bolts 160.
Any numerical values recited herein or in the figures are intended to include all values from the lower value to the upper value in increments of one unit provided that there is a separation of at least 2 units between any lower value and any higher value. As an example, if it is stated that the amount of a component or a value of a process variable such as, for example, temperature, pressure, time and the like is, for example, from 1 to 90, preferably from 20 to 80, more preferably from 30 to 70, it is intended that values such as 15 to 85, 22 to 68, 43 to 51, 30 to 32 etc. are expressly enumerated in this specification. For values which are less than one, one unit is considered to be 0.0001, 0.001, 0.01 or 0.1 as appropriate. These are only examples of what is specifically intended and all possible combinations of numerical values between the lowest value and the highest value enumerated are to be considered to be expressly stated in this application in a similar manner. As can be seen, the teaching of amounts expressed as “parts by weight” herein also contemplates the same ranges expressed in terms of percent by weight. Thus, an expression in the Detailed Description of the Invention of a range in terms of at “‘x’ parts by weight of the resulting polymeric blend composition” also contemplates a teaching of ranges of same recited amount of “x” in percent by weight of the resulting polymeric blend composition.”
Unless expressly stated, all ranges are intended to include both endpoints and all numbers between the endpoints. The use of “about” or “approximately” in connection with a range applies to both ends of the range. Thus, “about 20 to 30” is intended to cover “about 20 to about 30”, inclusive of at least the specified endpoints.
The use of the term “consisting essentially of” to describe a combination shall include the elements, ingredients, components or steps identified, and such other elements ingredients, components or steps that do not materially affect the basic and novel characteristics of the combination. The use of the terms “comprising” or “including” to describe combinations of elements, ingredients, components or steps herein also contemplates embodiments that consist essentially of the elements, ingredients, components or steps. By use of the term “may” herein, it is intended that any described attributes that “may” be included are optional.
The disclosure of “a” or “one” to describe an element, ingredient, component or step is not intended to foreclose additional elements, ingredients, components or steps. Plural elements, ingredients, components or steps can be provided by a single integrated element, ingredient, component or step. Alternatively, a single integrated element, ingredient, component or step might be divided into separate plural elements, ingredients, components or steps.
It is understood that the present description is intended to be illustrative and not restrictive, Many embodiments as well as many applications besides the examples provided will be apparent to those of skill in the art upon understanding the present disclosure. The scope of the claimed invention should, therefore, not be determined with limiting reference to the description, but should instead be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled. Any disclosure of an article or reference, including patent applications and publications, is incorporated by reference herein for all purposes. Any omission in the following claims of any aspect of subject matter disclosed herein is not a disclaimer of such subject matter.
