Abstract

An ATV is shown having a radiator that is coupled to the frame forward of and a hood is rotatably coupled to the frame and having an open position providing access to the radiator and a closed position enclosing the radiator.

First claim

What is claimed is:

1. An all-terrain vehicle (ATV), comprising:
a frame comprised of a main frame portion and a front frame subassembly, wherein the front frame subassembly comprises substantially vertical members and rearwardly extending members;
ground engaging members supporting the frame, including front and rear ground engaging members;
a steering input mechanism;
a radiator coupled to the frame forward of the steering input mechanism; and
a hood rotatably coupled to the frame and having an open position providing access to the radiator and a closed position enclosing the radiator;
a winch coupled to a rear side of the substantially vertical members; and
an air intake assembly supported by the frame, and a first portion of the hood is positioned adjacent the radiator and a second portion of the hood is positioned adjacent the air intake assembly, and the second portion of the hood is at a vertical position greater than the first portion of the hood relative to a ground surface.

2. The ATV of claim 1 , wherein the steering input mechanism comprises handle bars.

3. The ATV of claim 1 , wherein the radiator is positioned at an angle relative to a horizontal axis.

4. The ATV of claim 3 , wherein the radiator is positioned at an angle of less than 45 degrees relative to a horizontal axis.

5. The ATV of claim 4 , wherein the radiator is positioned within a range of 30-40 degrees relative to a horizontal axis.

6. The ATV of claim 5 , wherein the radiator is positioned at an angle of approximately 35 degrees relative to a horizontal axis.

7. The ATV of claim 1 , wherein the hood is coupled about a front of the vehicle frame, whereby the hood rotates towards a front of the vehicle.

8. The ATV of claim 1 , wherein the radiator is coupled to the rearwardly extending members of the front frame subassembly.

9. The ATV of claim 1 , wherein the hood is coupled to the front frame subassembly forward of the radiator.

10. The ATV of claim 1 , wherein the hood comprises an integrated grill having air vents therethrough for directing air onto the radiator for cooling purposes.

11. The ATV of claim 10 , wherein a first set of vents is directed at an angle substantially transverse to a front face of the radiator.

12. The ATV of claim 11 , wherein a second set of vents is directed at an angle substantially parallel to a front face of the radiator.

13. The ATV of claim 1 , further comprising a brush guard coupled to a front side of the substantially vertical members, wherein the substantially vertical are positioned longitudinally intermediate the brush guard and the winch.

14. The ATV of claim 1 , further comprising footwells mounted rearward of the front frame subassembly.

15. The ATV of claim 1 , further comprising a cargo area, and wherein the air intake assembly is at a vertical position greater than a vertical position of the cargo area relative to a ground surface.

16. An all-terrain vehicle (ATV), comprising:
a frame comprised of a main frame portion and a front frame subassembly, wherein the front frame subassembly comprises substantially vertical members and rearwardly extending members;
ground engaging members supporting the frame, including front and rear ground engaging members;
an operator area comprising a steering input mechanism, a seat, and footwells;
an engine supported by the frame and positioned within an envelope of the operator area;
a radiator coupled to an upper surface of the rearwardly extending members and generally parallel to the rearwardly extending members of the front frame subassembly;
a winch coupled to the substantially vertical members of the front frame subassembly, and the winch positioned forward of the radiator; and
an airbox positioned longitudinally intermediate the engine and the radiator and laterally intermediate the front ground engaging members.

17. The ATV of claim 16 , further comprising a hood rotatably coupled to the frame and having an open position providing access to the radiator and a closed position enclosing the radiator.

18. The ATV of claim 17 , wherein the radiator is positioned at an angle relative to a horizontal axis.

19. The ATV of claim 18 , wherein the radiator is positioned at an angle of less than 45 degrees relative to a horizontal axis.

20. The ATV of claim 17 , wherein the hood is coupled about a front of the vehicle frame, whereby the hood rotates towards a front of the vehicle.

21. The ATV of claim 17 , wherein the hood comprises an integrated grill having air vents therethrough for directing air onto the radiator for cooling purposes.

22. The ATV of claim 21 , wherein the grill includes a first set of vents is directed at an angle substantially transverse to a front face of the radiator.

23. The ATV of claim 22 , wherein the grill includes a second set of vents is directed at an angle substantially parallel to a front face of the radiator.

24. The ATV of claim 16 , wherein the winch is coupled to a rear side of the substantially vertical members.

25. The ATV of claim 16 , wherein the hood is coupled to the front frame subassembly forward of the radiator.

26. The ATV of claim 16 , further comprising a seat supported by the frame, and the airbox is longitudinally aligned with the seat.

27. The ATV of claim 16 , wherein the airbox is longitudinally aligned with the steering input mechanism.

28. The ATV of claim 27 , wherein the steering input mechanism is comprised of laterally extending handlebars.

29. The ATV of claim 16 , wherein the airbox comprises at least one duct fluidly coupled to the engine.
