Abstract

A hood guiding system for a work vehicle may include first and second walls positioned within an engine compartment of the work vehicle. The system may also include a hood configured to extend in a crosswise direction of the work vehicle between a first side and a second side so as to least partially cover the engine compartment. Additionally, the system may include a first guide component coupled to the hood at or adjacent to its first side and a second guide component coupled to the hood at or adjacent to its second side. When the hood is moved from an opened position to a closed position, the first and second guide components may be configured to contact outer surfaces of the first and second walls, respectively, to guide the hood towards the closed position.

First claim

What is claimed is:

1. A hood guiding system for a work vehicle, the system comprising:
a first wall positioned within an engine compartment of the work vehicle;
a first guide member coupled to the first wall;
a second wall positioned within the engine compartment of the work vehicle, the first and second walls being spaced apart from each other in a cross-wise direction of the work vehicle;
a second guide member coupled to the second wall;
a hood configured to extend in a lengthwise direction of the work vehicle between a forward end and an aft end and in the cross-wise direction between a first side and a second side so as to at least partially cover the engine compartment, the hood being pivotally coupled to a portion of the work vehicle such that the forward end is configured to be moved upwardly and downwardly relative to the engine compartment to move the hood between an opened position and a closed position;
a first guide component coupled to the hood at or adjacent to the first side of the hood; and
a second guide component coupled to the hood at or adjacent to the second side of the hood,
wherein, when the hood is moved from the opened position to the closed position, the first and second guide components are configured to contact the first and second guide members, respectively, prior to contacting outer surfaces of the first and second walls, respectively, to guide the hood towards the closed position.

2. The system of claim 1 , wherein the first and second guide components are configured to transition from outer guide surfaces defined by the first and second guide members to the outer surfaces of the first and second walls as the hood is moved towards the closed position.

3. The system of claim 1 , wherein the first guide member includes a first base portion coupled to the first wall and a first angled portion extending inwardly from the first base portion towards the second wall and wherein the second guide member includes a second base portion coupled to the second wall and a second angled portion extending inwardly from the second base portion towards the first wall.

4. The system of claim 3 , wherein, when the hood is moved from the opened position to the closed position, the first and second guide components are configured to contact the first and second angled portions, respectively, prior to contacting the outer surface of the first and second walls.

5. The system of claim 1 , wherein the first guide component comprises a first guide roller and the second guide component comprises a second guide roller.

6. The system of claim 5 , wherein a cross-wise width defined between the first and second guide components in the cross-wise direction of the work vehicle is less than a corresponding cross-wise width is defined between the outer surfaces of the first and second walls when the hood is at the opened position.

7. The system of claim 5 , wherein the first guide roller is rotationally supported by a first mounting bracket coupled to the hood at or adjacent to the first side of the hood and the second guide roller is rotationally supported by a second mounting bracket coupled to the hood at or adjacent to the second side of the hood.

8. The system of claim 7 , wherein the first mounting bracket is coupled to a first flange extending inwardly from the first side of the hood and the second mounting bracket is coupled to a second flange extending inwardly from the second side of the hood.

9. The hood guiding system of claim 1 , wherein the first and second walls correspond to first and second sidewalls of a cooling module of the work vehicle, the cooling module including at least one heat exchange component.

10. A work vehicle, comprising:
a cooling module positioned within an engine compartment of the work vehicle, the cooling module including at least one heat exchange component and first and second sidewalls spaced apart from each other in a cross-wise direction of the work vehicle;
a hood configured to extend in a lengthwise direction of the work vehicle between a forward end and an aft end and in the cross-wise direction between a first side and a second side so as to at least partially cover the engine compartment, the hood being pivotally coupled to a portion of the work vehicle such that the forward end is configured to be moved upwardly and downwardly relative to the cooling module to move the hood between an opened position and a closed position;
a first guide roller coupled to the hood at or adjacent to the first side of the hood; and
a second guide roller coupled to the hood at or adjacent to the second side of the hood,
wherein, when the hood is moved from the opened position to the closed position, the first and second guide rollers are configured to contact outer surfaces of the first and second sidewalls, respectively, to guide the hood towards the closed position.

11. The work vehicle claim 10 , further comprising a first guide member coupled to the first sidewall and a second guide member coupled to the second sidewall.

12. The work vehicle claim 11 , wherein, when the hood is moved from the opened position to the closed position, the first and second guide rollers are configured to contact the first and second guide members, respectively, prior to contacting the outer surface of the first and second sidewalls.

13. The work vehicle claim 12 , wherein the first and second guide rollers are configured to transition from outer guide surfaces defined by the first and second guide members to the outer surfaces of the first and second side walls as the hood is moved towards the closed position.

14. The work vehicle claim 11 , wherein the first guide member includes a first base portion coupled to the first sidewall and a first angled portion extending inwardly from the first base portion towards the second sidewall and wherein the second guide member includes a second base portion coupled to the second sidewall and a second angled portion extending inwardly from the second base portion towards the first sidewall.

15. The work vehicle of claim 14 , wherein, when the hood is moved from the opened position to the closed position, the first and second guide rollers are configured to contact the first and second angled portions, respectively, prior to contacting the outer surface of the first and second sidewalls.

16. The work vehicle of claim 14 , wherein a portion of an outer guide surface defined by the first base portion is substantially coplanar with the outer surface of the first sidewall and wherein a portion of an outer guide surface defined by the second base portion is substantially coplanar with the outer surface of the second sidewall.

17. The work vehicle claim 11 , wherein a cross-wise width defined between the first and second guide rollers in the cross-wise direction of the work vehicle is less than a corresponding cross-wise width defined between the outer surfaces of the first and second sidewalls when the hood is at the opened position.

18. The work vehicle claim 11 , wherein the first guide roller is rotationally supported by a first mounting bracket coupled to the hood at or adjacent to the first side of the hood and the second guide roller is rotationally supported by a second mounting bracket coupled to the hood at or adjacent to the second side of the hood.
