Abstract

A winch assembly is described and shown herein. The winch assembly may include a first housing member having a first retaining member formed therein and a second housing member having a second retaining member formed therein, the second housing member secured to the first housing member forming a winch housing. The winch assembly may further include a drive system generally positioned within the winch housing, and a winch drum operatively coupled with the drive system and rotationally secured with the first and second retaining members.

Claims

1. A winch assembly comprising:

a first housing member having a first retaining member formed therein;

a second housing member having a second retaining member formed therein, the second housing member secured to the first housing member forming a winch housing;

a drive system entirely positioned within the winch housing; and

a winch drum operatively coupled with the drive system and rotationally secured with the first and second retaining members.

2. The winch assembly of claim 1, further comprising:

a drive shaft operatively coupled with the drive system;

a first pocket positioned in the first housing member; and

a second pocket positioned with the second housing, wherein the first and second pockets rotationally secure the drive shaft with the first and second housing members.

3. The winch assembly of claim 2, further comprising first and second bushings attached to the drive shaft wherein the first bushing operatively fits within the first pocket and the second bushing operatively fits within the second pocket.

4. The winch assembly of claim 1, wherein the first retaining member is monolithically formed with the first housing member.

5. The winch assembly of claim 1, wherein the second retaining member is monolithically formed with the second housing member.

6. A winch assembly comprising:

a first housing member;

a second housing member generally vertically aligned with the first housing member and secured to the first housing member to form a winch housing;

a drive system operatively coupled with the first and second housing members; and

a winch drum operatively coupled with the drive system and the first and second housing members, wherein the winch housing entirely encases the drive system and winch drum on at least three sides.

7. The winch assembly of claim 6, wherein the winch housing entirely encases the drive system and winch drum on four sides.

8. The winch assembly of claim 6, wherein the winch drum is rotationally secured with the first and second housing members.

9. The winch assembly of claim 6, wherein at least one of the first and second housing members is formed as a monolithic member.

10. The winch assembly of claim 6, further comprising a strap guide formed in the winch housing.

11. The winch assembly of claim 10, further comprising a first recessed portion formed in the first housing member and a second recessed portion formed in the second housing member, wherein the first and second recessed portions form the strap guide.

12. The winch assembly of claim 11, wherein the winch drum is free of a sump.

13. The winch assembly of claim 10, wherein a position of the strap guide relative to the winch housing is fixed.

14. A winch assembly comprising:

a first housing member;

a second housing member secured to the first housing member to form a winch housing, wherein at least one of the first and second housing members includes a slot formed therein;

a drive system generally positioned within the winch housing;

a winch drum operatively coupled with the drive system and positioned within the winch housing; and

wherein the first and second housing members directly support the winch drum.

15. The winch assembly of claim 14, further comprising a ratchet and pawl, wherein at least a portion of the ratchet and pawl extend through the slot.

16. The winch assembly of claim 15, further comprising a boss integrally formed in at least one of the first and second housing members wherein a portion of the ratchet and pawl is operatively coupled with the boss.

17. The winch assembly of claim 14, further comprising a first retaining member integrally formed with the first housing and a second retaining member integrally formed with the second housing, wherein the winch drum is rotatably secured between the first and second retaining members.

18. The winch assembly of claim 17, wherein the first retaining member includes a first tubular member and the second retaining member includes a second tubular member, wherein the winch drum is rotationally and operatively coupled in the first and second tubular members.

19. The winch assembly of claim 18, further comprising a first bushing positioned in the first tubular member and coupled with the winch drum and a second bushing positioned in the second tubular member and coupled with the winch drum, wherein the winch drum rotates within the first and second bushings.

20. The winch assembly of claim 14, wherein the first and second housing members directly support the winch drum without any fasteners.
