Abstract

A utility vehicle with ergonomic, safety, and maintenance features is disclosed. A vehicle is also disclosed with improved cooling, suspension and drive systems. These features enhance the utility of the vehicle.

Claims (50)

1. A utility vehicle, comprising:

a frame extending along a centerline of the utility vehicle and having a front section, a midsection, and a rear section, the frame defining a cab rearward of the front section;

a plurality of ground engaging members operably coupled to the frame;

an engine supported by the frame along the centerline;

a drive shaft spaced apart from the engine;

a transfer case operably coupled to the drive shaft and supported by the front section of the frame; and

a front differential operably coupled to the transfer case and supported by the frame, the differential being positioned along the centerline.

2. The utility vehicle of claim 1 , wherein the drive shaft is a front drive shaft including a rear end positioned rearward of the engine and a front end positioned forward of the engine.

3. The utility vehicle of claim 2 , further comprising:

a transmission operably coupled to the engine;

a rear drive shaft operably coupled to the transmission and spaced apart from the front drive shaft; and

a rear differential operably coupled to the rear drive shaft and extending along the centerline of the utility vehicle.

4. The utility vehicle of claim 3 , further comprising a rear transfer case operably coupled to the transmission, the rear drive shaft, and the front drive shaft.

5. The utility vehicle of claim 1 , wherein an inner end of the transfer case is positioned at the centerline of the utility vehicle and an outer end of the transfer case extends laterally outward from the centerline toward the front end of the drive shaft.

6. The utility vehicle of claim 1 , wherein the transfer case transmits an output from the drive shaft to an input of the front differential.

7. The utility vehicle of claim 1 , wherein the frame is configured to support more than one type of the front differential.

8. The utility vehicle of claim 1 , wherein the front differential is configured for approximately 7,000 lb-ft of torque.

9. A utility vehicle, comprising:

a frame extending along a centerline of the utility vehicle;

a plurality of ground engaging members operably coupled to the frame;

a front suspension assembly operably coupled to a portion of the plurality of ground engaging members; and

a drivetrain assembly supported by the frame and including:

an engine supported by the frame;

a drive shaft off-center from the centerline, the drive shaft having an input end operably coupled to the engine and an output end;

a differential positioned along the centerline and having an input end operably coupled to the drive shaft and an output end operably coupled to the ground engaging members; and

a transfer case operably coupled to the differential, the transfer case and the differential being positioned within an envelope of the front suspension assembly.

10. The utility vehicle of claim 9 , wherein the engine is positioned along the centerline and the drive shaft is positioned laterally outward from a side of the engine.

11. The utility vehicle of claim 9 , wherein the transfer case is supported at a front portion of the frame and extends outward from the centerline toward the drive shaft.

12. The utility vehicle of claim 9 , wherein the differential extends below a lower plane of the envelope of the front suspension assembly.

13. The utility vehicle of claim 9 , wherein the frame includes a frame member coupled to a suspension mount for supporting the front suspension assembly and a transfer case mount for supporting the transfer case.

14. The utility vehicle of claim 13 , wherein the transfer case extends laterally outward beyond the suspension mount.

15. The utility vehicle of claim 9 , wherein the front suspension assembly includes at least a first control arm and a shock absorber, and at least a portion of the shock absorber is longitudinally forward of the transfer case.

16. The utility vehicle of claim 15 , wherein the shock absorber is longitudinally intermediate the differential and the transfer case.

17. The utility vehicle of claim 15 , wherein the first control arm includes a front leg and a rear leg, and the differential and the transfer case are positioned longitudinally intermediate the front and rear legs.

18. The utility vehicle of claim 15 , wherein the front suspension further includes a second control arm, and the second control arm is longitudinally forward of the transfer case.

19. The utility vehicle of claim 18 , wherein the second control is longitudinally forward of at least a portion of the differential.

20. A utility vehicle, comprising:

a frame extending along a centerline of the utility vehicle and having a front section, a midsection, and a rear section, the frame defining a cab rearward of the front section;

a plurality of ground engaging members operably coupled to the frame;

a front suspension assembly operably coupled to a portion of the ground engaging members;

a steering assembly operable coupled to the portion of the ground engaging members and comprising at least a steering arm;

an engine supported by the frame along the centerline at a position generally forward of the rear section;

a drive shaft spaced apart from the engine;

a transfer case operably coupled to the drive shaft and supported by the front section of the frame; and

a front differential operably coupled to the transfer case and supported by the frame, the differential being positioned along the centerline, wherein the steering arm is positioned forward of the front differential.

21. The utility vehicle of claim 20 , wherein the steering assembly further comprises a power steering unit, and the power steering unit is positioned within an envelope of the front suspension assembly.

22. The utility vehicle of claim 21 , wherein the front suspension assembly includes lower control arms, upper control arms, and shock absorbers, and the power steering unit is positioned generally along the centerline and vertically intermediate the upper and lower control arms.

23. The utility vehicle of claim 22 , wherein the power steering unit and the front differential are positioned forward of the shock absorbers.

24. The utility vehicle of claim 22 , wherein the steering assembly further comprises a gearbox, and the gearbox and the power steering unit are positioned forward of the shock absorbers.

25. The utility vehicle of claim 22 , wherein each of the lower control arms includes a front leg and a rear leg, and the differential and the transfer case are positioned longitudinally intermediate the front and rear legs.
