Abstract

An engine enclosure for enclosing an engine of a work machine. The enclosure includes a first panel hingedly supported from an enclosure top and extending downwardly therefrom to form an enclosure side portion. A first hinge device joins the first panel to the enclosure top for pivotal movement relative thereto, the first panel pivotable from a closed position to an open position for access of engine components. A second panel hingedly supports and forms another portion of the enclosure side, extending upwardly toward the first panel. A lower portion of the first panel is configured to overlie an upper portion of the second panel when the first and second panels are in a closed position for preventing pivotal movement of the second panel when the first panel overlies the second panel. The second panel is pivotable from the closed position to an open position for access of engine components.

Claims (29)

1. An engine enclosure for enclosing an engine of a work machine, the enclosure comprising:

a first panel hingedly supported from an enclosure top and extending downwardly therefrom to form an enclosure side portion;

a first hinge device joining the first panel to the enclosure top for pivotal movement relative thereto, the first panel pivotable from a closed position to an open position for access of engine components without the first panel contacting a drive device of the work machine;

a second panel hingedly supported and forming another portion of the enclosure side, extending upwardly toward the first panel, wherein a lower portion of the first panel is configured to overlie an upper portion of the second panel when the first and second panels are in a closed position for preventing pivotal movement of the second panel when the first panel overlies the second panel; and

wherein the second panel is pivotable from the closed position to an open position for access of engine components.

2. The engine enclosure of claim 1 , wherein the second panel includes a latch device to secure the second panel in the closed position when the first panel is in the open position.

3. The engine enclosure of claim 1 , wherein the second panel is contoured to be in at least one of close conformal proximity and conformal abutting contact with the drive device when disposed in the open position.

4. The engine enclosure of claim 1 , wherein the second panel is removable without tools once the second panel is pivoted a predetermined amount from the closed position.

5. The engine enclosure of claim 1 , wherein a resilient layer is secured along at least a fraction of the lower portion of the first panel to resiliently abut a corresponding region of the upper portion of the second panel when the first and second panel are in the closed position.

6. The engine enclosure of claim 5 , wherein the resilient layer forms a bulb seal between the first and second panel.

7. The engine enclosure of claim 1 , wherein a resilient layer is secured along at least a fraction of the upper portion of the second panel to resiliently abut a corresponding region of the lower portion of the first panel when the first and second panel are in the closed position.

8. The engine enclosure of claim 7 , wherein the resilient layer forms a bulb seal between the first and second panel.

9. The engine enclosure of claim 1 , wherein the second panel is a nonmetal.

10. The engine enclosure of claim 1 , wherein the second panel is a plastic.

11. The engine enclosure of claim 1 , wherein the second panel is pivotably connected to a pivot block.

12. The engine enclosure of claim 1 , wherein the drive device is a wheel.

13. The engine enclosure of claim 1 , wherein the drive device is a drive track.

14. The engine enclosure of claim 1 , wherein the second panel is pivotable from the closed position to an open position for access of engine components without the second panel contacting the drive device of the work machine.

15. A work machine comprising:

an engine and an engine enclosure, the engine enclosure comprising:

a first panel hingedly supported from an enclosure top and extending downwardly therefrom to form an enclosure side portion;

a first hinge device joining the first panel to the enclosure top for pivotal movement relative thereto, the first panel pivotable from a closed position to an open position for access of engine components without the first panel contacting a drive device of the work machine;

a second panel hingedly supported and forming another portion of the enclosure side, extending upwardly toward the first panel, wherein a lower portion of the first panel is configured to overlie an upper portion of the second panel when the first and second panels are in a closed position for preventing pivotal movement of the second panel when the first panel overlies the second panel; and

wherein the second panel is pivotable from the closed position to an open position for access of engine components.

16. The work machine of claim 15 , wherein the second panel includes a latch device to secure the second panel in the closed position when the first panel is in the open position.

17. The work machine of claim 15 , wherein the second panel is contoured to be in close conformal proximity with the drive device when disposed in the open position.

18. The work machine of claim 15 , wherein the second panel is removable without tools once the second panel is pivoted a predetermined amount from the closed position.

19. The work machine of claim 15 , wherein a resilient layer is secured along at least a fraction of the lower portion of the first panel to resiliently abut a corresponding region of the upper portion of the second panel when the first and second panel are in the closed position.

20. The work machine of claim 15 , wherein the second panel is pivotably connected to a pivot block.
