Abstract

A utility vehicle includes a plurality of ground-engaging members, a frame assembly, a cab frame assembly, a front suspension assembly, a rear suspension assembly, a power steering assembly, and a powertrain assembly, all of which may be configured to lower the center of gravity of the vehicle.

First claim

What is claimed is:

1. A utility vehicle, comprising:
a plurality of front ground engaging members;
a plurality of rear ground engaging members positioned rearward of the front ground engaging members;
a frame assembly supported by the front and rear ground engaging members;
a powertrain assembly operably coupled to the front and rear ground engaging members;
a front suspension assembly operably coupled to the front ground engaging members, the front suspension assembly including an upper alignment arm, a lower alignment arm, and a steering arm each coupled to a hub assembly, wherein the upper alignment arm is positioned vertically above the steering arm.

2. The utility vehicle of claim 1 , wherein the upper alignment arm includes a first end and a second end and the steering arm includes a first end and a second end, wherein the first end of the upper alignment arm is positioned rearward of the first end of the steering arm and the second end of the upper alignment arm is positioned forward of the second end of the steering arm.

3. The utility vehicle of claim 1 , wherein the upper alignment arm includes an upward bend beneath which the steering arm is positioned.

4. The utility vehicle of claim 1 , wherein the upper alignment arm includes a forward upper alignment arm and a rearward upper alignment arm, wherein the rearward upper alignment arm is positioned crossing the steering arm vertically above the steering arm.

5. The utility vehicle of claim 4 , wherein the lower alignment arm includes a forward lower alignment arm and a rearward lower alignment arm, wherein the rearward lower alignment arm is positioned crossing the steering arm vertically below the steering arm.

6. The utility vehicle of claim 5 , wherein the rearward upward alignment arm includes a bend positioned vertically above the steering arm.

7. The utility vehicle of claim 6 , wherein the bend includes a concave side and a convex side, wherein the concave side of the bend is positioned toward the steering arm.

8. The utility vehicle of claim 1 , wherein the hub assembly includes a king pin axis that is angled relative to a vertical axis of the hub assembly when the utility vehicle is a horizontal orientation.

9. The utility vehicle of claim 8 , wherein the king pin axis is angled rearward relative to the vertical axis of the hub assembly above a center point of the hub assembly.

10. The utility vehicle of claim 8 , wherein the rearward lower alignment arm includes a bend, the bend includes a concave side and a convex side, wherein the convex side is positioned toward the king pin axis.

11. A utility vehicle, comprising:
a plurality of front ground engaging members;
a plurality of rear ground engaging members positioned rearward of the front ground engaging members;
a frame assembly supported by the front and rear ground engaging members;
a powertrain assembly operably coupled to the front and rear ground engaging members;
a front suspension assembly operably coupled to the front ground engaging members, the front suspension assembly including an upper alignment arm, a lower alignment arm, and a steering arm each coupled to a hub assembly, wherein the upper alignment arm is positioned traversing across a longitudinal axis of the steering arm from a rearward side to a forward side of the steering arm.

12. The utility vehicle of claim 11 , wherein the upper alignment arm is positioned vertically above the steering arm.

13. The utility vehicle of claim 11 , wherein the upper alignment arm includes a curved profile.

14. The utility vehicle of claim 13 , wherein the curved profile defines a convex side and a concave side, wherein the concave side of the curved profile of the upper alignment arm is positioned facing the steering arm.

15. The utility vehicle of claim 11 , wherein the upper alignment arm includes a first end and a second end and the steering arm includes a first end and a second end, wherein the first end of the upper alignment arm is positioned rearward of the first end of the steering arm and the second end of the upper alignment arm is positioned forward of the second end of the steering arm.

16. The utility vehicle of claim 15 , wherein the first end of the upper alignment arm is positioned vertically higher than the first end of the steering arm.

17. The utility vehicle of claim 15 , wherein the second end of the upper alignment arm is positioned vertically higher than the second end of the steering arm.

18. The utility vehicle of claim 15 , wherein the first and second ends of the upper alignment arm are positioned vertically higher than the first and second ends of the second arm.

19. The utility vehicle of 56 , wherein the lower alignment arm is positioned crossing the steering arm vertically below the steering arm.

20. The utility vehicle of claim 11 , wherein the steering arm is positioned intermediate the upper alignment arm and the lower alignment arm.
