Abstract

A vehicle includes a frame, front and rear wheels, a powertrain comprising an engine and transmission, and various other systems and components. The frame includes various features for supporting components and systems of the vehicle. For example, a rear portion of the frame is configured to support a utility bed, a portion of a cooling system, a portion of an air intake system, and a portion of an exhaust system.

First claim

The invention claimed is:

1. A vehicle, comprising:
a frame;
front and rear wheels;
a front suspension coupled to the frame;
a powertrain drivingly coupled to the front and rear wheels, comprising a front final drive drivingly coupled to the front wheels;
a front prop shaft coupling the powertrain to the front wheels;
a steering mechanism positioned above the prop shaft and rearward of the final drive; and
wherein the front prop shaft is defined by a first prop shaft portion extending longitudinally and a front coupling extending upwardly to the front final drive, the front prop shaft and the front coupling defining an inclusive angle.

2. The vehicle of claim 1 , wherein the steering mechanism is positioned in the inclusive angle.

3. The vehicle of claim 2 , further comprising a stabilizer bar positioned generally over a top of the final drive and coupled between the right and left suspension.

4. The vehicle of claim 3 , wherein the stabilizer bar includes a transverse rod coupled to link arms which in turn are coupled to link rods, and wherein link rods are coupled to the lower A-arms.

5. The vehicle of claim 4 , wherein a left side half shaft is coupled between the left wheel and a front final drive and a right half shaft is coupled between the right wheel and the front final drive.

6. The vehicle of claim 5 , further comprising a left side steering arm coupled between the left wheel and the steering mechanism and a right side steering arm coupled between the right wheel and the steering mechanism.

7. The vehicle of claim 6 , wherein the link rods extend between the half shafts and the steering arms on the right and left hand sides of the vehicle.

8. The vehicle of claim 7 , wherein the half shafts are forward of the steering arms.

9. The vehicle of claim 1 , wherein the front suspension includes upper and lower A-arms on a left and right hand side of the vehicle.

10. The vehicle of claim 9 , wherein the front suspension further comprises a linear force element coupled between the frame and one of the upper and lower A-arms on each side of the vehicle.

11. The vehicle of claim 10 , wherein the linear force element is coupled to the lower A-arms on each side of the vehicle.

12. The vehicle of claim 11 , wherein a left side half shaft is coupled between the left wheel and the front final drive and a right half shaft is coupled between the right wheel and the front final drive.

13. The vehicle of claim 12 , wherein a coupling between the linear force elements and the lower A-arms straddles the half shafts.

14. The vehicle of claim 13 , wherein the coupling between the linear force elements and the lower A-arms is a clevis.

15. The vehicle of claim 14 , wherein the clevis is elongated in the vertical direction to allow the free movement of the half shaft within the clevis during the operating movement of the suspension.

16. The vehicle of claim 15 , wherein an axis 4 that runs down the axial center of the linear force element intersects the half shaft.

17. A vehicle, comprising:
a frame;
front and rear wheels;
a front suspension coupled to the frame comprising upper and lower A-arms on a left and right hand side of the vehicle, a linear force element coupled between the frame and the lower A-arms on each side of the vehicle;
a powertrain drivingly coupled to the front and rear wheels, comprising a front final drive drivingly coupled to the front wheels;
a left side half shaft coupled between the left wheel and the front final drive;
a right half shaft coupled between the right wheel and the front final drive; and
a coupling between the linear force elements and the lower A-arms straddles the half shafts such that the half shafts extend horizontally between the wheels and the front final drive.

18. The vehicle of claim 17 , wherein the coupling between the linear force elements and the lower A-arms is a clevis.

19. The vehicle of claim 18 , wherein the clevis is elongated in the vertical direction to allow the free movement of the half shaft within the clevis during the operating movement of the suspension.

20. The vehicle of claim 17 , wherein the powertrain further comprises a power source and a front prop shaft couples the powertrain to the front final drive.

21. The vehicle of claim 20 , wherein a steering mechanism is positioned above the prop shaft and rearward of the final drive.

22. The vehicle of claim 21 , wherein the front prop shaft is defined by a first shaft portion extending longitudinally and a front coupling extending upwardly to the final drive, the first shaft portion and the front coupling defining an inclusive angle and the steering mechanism being positioned in the inclusive angle.

23. A vehicle, comprising:
a frame;
front and rear wheels;
a front suspension coupled to the frame comprising upper and lower A-arms;
a powertrain drivingly coupled to the front and rear wheels, comprising a front final drive drivingly coupled to the front wheels;
a front prop shaft coupling the powertrain to the front wheels; and
a stabilizer bar positioned generally over a top of the final drive, wherein the stabilizer bar is coupled to link rods directly coupled with the lower A-arms.

24. The vehicle of claim 23 , wherein the stabilizer bar includes a transverse rod coupled to link arms which in turn are coupled to the link rods.

25. The vehicle of claim 24 , wherein the link arms are discrete from the transverse rod.

26. The vehicle of claim 23 , wherein further comprising a steering mechanism positioned above the prop shaft and rearward of the final drive.
