Arcuate frame for a vehicle
View Patent ↗An all-terrain 4 wheeled vehicle with a frame comprising an arcuate shape. In one embodiment, the arcuate shape extends from a rear axis to a front axis such that there is additional clearance over a typical non arcuate frame at a given ride height. The arcuate frame may also provide for additional structural strength. The frame may also include the ability to attach periphery accessories such as an engine cage, a passenger cage, trailing arms, power train and transmission.

6. The All-Terrain Vehicle of claim 1 , wherein the continuous arcuate shaped portion extends at least 40% of the longitudinal length between the front wheel axis and the rear wheel axis.
7. An All-Terrain Vehicle comprising:
a front wheel having a center axis extending through the front wheel;
a rear wheel having a center axis extending through the rear wheel;
a frame comprising;
a front lateral truss;
a rear lateral truss;
at least one longitudinal truss, having a rear end and a front end connecting to the front and the rear lateral truss;
wherein the longitudinal truss is arcuate shaped having a continuous arc shape from the front truss and the rear truss with an apex between the front truss and the rear truss; and
wherein the apex of the continuous arcuate shaped longitudinal truss is elevated more than 2 inches above a straight line connecting the front wheel center axis and the rear wheel center axis.
8. The All-Terrain Vehicle frame of claim 7 wherein the apex is located at a mid-point between the front lateral truss and the rear lateral truss.
9. The All-Terrain Vehicle frame of claim 7 wherein the arcuate shaped longitudinal truss has a radius of 9 ft or more.
10. An All-Terrain Vehicle comprising:
front wheels with a center, and a front wheel axis connecting the center of the front wheels;
rear wheels with a center, and a rear wheel axis connecting the center of the rear wheels;
a frame comprising:
a front end,
a rear end,
a first side,
a second side,
a top side,
a bottom side, and
a center portion;
wherein the front end, rear end, first side, second side, top side, bottom side define an outer periphery; and
wherein the center portion is within the outer periphery, and
wherein the center portion extending longitudinally between the front axis and the rear axis is arcuate shaped;
wherein the center portion comprising a continuous arcuate shaped portion located at a center point between the front wheel axis and rear wheel axis and wherein the continuous arcuate shaped portion extends from a center point, between the front wheel axis and rear wheel axis, toward the front and rear wheel axes; and
wherein the continuous arcuate shaped portion of the center portion has an apex elevated above at least 2 inches above a straight line connecting the rear wheel axis and the front wheel axis.
11. The All-Terrain Vehicle of claim 10 ,
wherein the continuous arcuate shaped portion of the center portion extends at least 40% of a longitudinal length between the front wheel axis and the rear wheel axis.
12. The All-Terrain Vehicle of claim 10 , wherein the frame comprises tubular construction.
13. The All-Terrain Vehicle of claim 10 , wherein the continuous arcuate shaped portion of the center portion has an apex elevated above at least 5 inches above a straight line connecting the rear wheel axis and the front wheel axis.
14. The All-Terrain Vehicle of claim 10 , wherein the center portion is continuously arcuate shaped from the front wheel axis and the rear wheel axis.
15. The All-Terrain Vehicle of claim 10 , wherein the frame further comprises an engine support structure, wherein the engine support structure rises above a plane connecting the rear wheel axis and the front wheel axis.
16. The All-Terrain Vehicle of claim 1 , wherein the apex is located at a midpoint between the front wheel axis and the rear wheel axis.
17. The All-Terrain Vehicle of claim 1 , wherein the structural component that extends between the front wheel axis and the rear wheel axis does not extend below a line extending between said front wheel axis and the rear wheel axis.
18. The All-Terrain Vehicle of claim 1 , wherein the frame comprises a tubular construction.
19. The All-Terrain Vehicle of claim 1 , wherein the frame continues rearward of the rear wheel axis and rises above a plane connecting the rear wheel center axis and the front wheel center axis.
20. The All-Terrain Vehicle of claim 7 , wherein the frame comprises tubular construction.
