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 steering assembly comprising at least one steering arm operably coupled to one of the front ground engaging members; and
a front suspension assembly comprising:
a lower alignment arm operably coupled to the one of the plurality of ground-engaging members,
an upper alignment arm operably coupled to the one of the plurality of ground-engaging members, a length of the upper alignment arm defining a clearance configured to accommodate the at least one steering arm, and the upper alignment arm including a first portion and a second portion, the second portion is positioned above the at least one steering arm, and
a linear force component operably coupled to the one of the plurality of ground-engaging members wherein the second portion is positioned rearward of the liner force component.

2. The utility vehicle of claim 1 , wherein the at least one steering arm is intermediate the upper alignment arm and the lower alignment arm.

3. The utility vehicle of claim 1 , wherein the linear force component comprises a shock absorber.

4. The utility vehicle of claim 1 , wherein the at least one steering arm is operably coupled to the one of the plurality of ground-engaging members at a position rearward of an axis of rotation of the one of the plurality of ground-engaging members.

5. The utility vehicle of claim 1 , wherein the suspension assembly further comprises a torsion bar positioned rearward of at least a portion of the steering assembly.

6. The utility vehicle of claim 5 , wherein the torsion bar is operably coupled to the upper alignment arm at a position forward of the at least one steering arm.

7. The utility vehicle of claim 6 , wherein the steering assembly further comprises a steering rack, and the torsion bar extends rearwardly of the at least one steering arm and is rearward of the steering rack.

8. The utility vehicle of claim 6 , wherein the at least one steering arm is positioned vertically intermediate the upper alignment arm and the torsion bar.

9. 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 steering assembly comprising at least one steering arm operably coupled to one of the front ground engaging members; and
a front suspension assembly comprising:
a lower alignment arm operably coupled to the one of the plurality of ground-engaging members, and
an upper alignment arm operably coupled to the one of the plurality of ground-engaging members, a length of the upper alignment arm defining a clearance configured to accommodate the at least one steering arm, the upper alignment arm including a first portion and a second portion, and wherein the second portion is positioned above the at least one steering arm and includes an outer end forward of the at least one steering arm and an inner end rearward of the at least one steering arm.

10. The utility vehicle of claim 9 , wherein the clearance of the upper alignment arm defines a curvature between the outer and inner ends.

11. The utility vehicle of claim 10 , wherein the curvature is at a height vertically greater than that of the inner and outer ends.

12. A utility vehicle, comprising:
a plurality of front ground engaging members;
a plurality of rear ground engaging members;
a frame supported by the front and rear ground engaging members;
a powertrain assembly operably coupled to the front and rear ground engaging members;
a steering assembly comprising at least one steering arm operably coupled to the powertrain assembly; and
a front suspension assembly comprising:
a lower alignment arm operably coupled to one of the front ground engaging members,
an upper alignment arm operably coupled to the one of the plurality of front ground-engaging members, and
a torsion bar operably coupled to the upper alignment arm,
wherein the at least one steering arm, the upper alignment arm, and the torsion bar are vertically aligned from a side view of the utility vehicle.

13. The utility vehicle of claim 12 , wherein the torsion bar has a first portion positioned forward of the at least one steering arm and a second portion positioned rearward of the at least one steering arm.

14. The utility vehicle of claim 13 , wherein the steering assembly further comprises a steering rack operably coupled to the at least one steering arm, and the second portion of the torsion bar is rearward of the steering rack.

15. The utility vehicle of claim 12 , wherein the torsion bar defines the rearward-most extent of the front suspension assembly.

16. The utility vehicle of claim 15 , wherein the upper alignment arm defines the forward-most extent of the front suspension assembly.

17. The utility vehicle of claim 12 , wherein the upper alignment arm intersects the at least one steering arm from a top view of the front suspension assembly.

18. The utility vehicle of claim 17 , wherein the torsion bar intersects the at least one steering arm from a top view of the front suspension assembly.

19. The utility vehicle of claim 12 , wherein the upper alignment arm includes an outer portion, an inner portion, and an intermediate portion extending generally laterally between the outer and inner portions, and a first vertical distance between the intermediate portion and the at least one steering arm is greater than a second vertical distance between the outer portion and the at least one steering arm.

20. The utility vehicle of claim 19 , wherein the intermediate portion is curved.
