Abstract

A drive sprocket for driving a track of a tracked vehicle is provided. The drive sprocket includes an interior ring, an exterior ring, and an intermediate ring situated between the interior ring and the exterior ring. The interior ring, exterior ring, and intermediate ring are oriented in a substantially spaced-apart manner, each of the rings have an outer peripheral surface. A plurality of rods is attached to the rings adjacent to the outer peripheral surface thereof. The interior, exterior, and intermediate rings have a substantially “U” or “J” shape.

First claim

What is claimed is:

1. A drive sprocket for driving a track of a tracked vehicle, said drive sprocket comprising:
an interior ring, an exterior ring, and an intermediate ring situated between said interior ring and said exterior ring; said interior ring, said exterior ring, and said intermediate ring are oriented in a substantially spaced-apart manner and are parallel with one another, each of said rings having an outer peripheral surface;
a plurality of rods attached to said rings adjacent to said outer peripheral surface thereof; and
wherein said interior ring, said exterior ring, and/or said intermediate ring have a substantially “U” or “J” shape, wherein said substantially “U” or “J” shape opens toward a rotational axis of said drive sprocket.

2. The drive sprocket as recited in claim 1 , wherein an inner guide ring, said outer guide ring, and a base ring of said interior ring form said substantially “U” or “J” shape of said interior ring, wherein said base ring is located between said inner guide ring and said outer guide ring.

3. The drive sprocket as recited in claim 1 , wherein a base ring, said inner guide ring, and a first portion of said outer guide ring of said interior ring form said substantially “U” shape of said interior ring.

4. The drive sprocket as recited in claim 1 , wherein an inner guide ring, an outer guide ring, and a base ring of said exterior ring form said substantially “U” or “J” shape of said exterior ring, wherein said base ring is located between said inner guide ring and said outer guide ring of said exterior ring.

5. The drive sprocket as recited in claim 1 , wherein a base ring, an outer guide ring, and a first portion of an inner guide ring of said exterior ring form said substantially “U” shape of said exterior ring.

6. The drive sprocket as recited in claim 1 , wherein an inner guide ring, an outer guide ring, and a base ring of said intermediate ring form said substantially “U” or “J” shape of said intermediate ring, wherein said base ring is located between said inner guide ring and said outer guide ring of said intermediate ring.

7. The drive sprocket as recited in claim 1 , wherein a base ring, an inner guide ring, and a first portion of an outer guide ring of said intermediate ring form said substantially “U” shape of said intermediate ring.

8. The drive sprocket as recited in claim 1 , wherein said “U” or “J” shape of said interior ring is configured to substantially fill a space between an interior guide lug and an interior drive lug arranged in an annular pattern on an inside surface of a track.

9. The drive sprocket as recited in claim 1 , wherein said “U” or “J” shape of said intermediate ring is configured to substantially fill a space between an exterior drive lug and an interior drive lug arranged in an annular pattern on an inside surface of a track.

10. The drive sprocket as recited in claim 1 , wherein said “U” or “J” shape of said exterior ring is configured to substantially fill a space between an exterior guide lug and an exterior drive lug arranged in an annular pattern on an inside surface of a track.

11. The drive sprocket as recited in claim 1 , a base ring of said interior ring is comprised of said outer peripheral surface located between said rods and an inner guide ring and said outer guide ring of said interior ring, wherein said outer peripheral surface is flat.

12. The drive sprocket as recited in claim 1 , a base ring of said exterior ring is further comprised of said outer peripheral surface located between said rods and an inner guide ring and an outer guide ring of said exterior ring, wherein said outer peripheral surface is flat.

13. The drive sprocket as recited in claim 1 , said base ring of said intermediate ring is further comprised of said outer peripheral surface located between said rods and an inner guide ring and an outer guide ring of said intermediate ring, wherein said outer peripheral surface is flat.

14. The drive sprocket as recited in claim 1 , wherein each of said plurality of rods is spaced-apart from adjacent rods.

15. The drive sprocket as recited in claim 1 , wherein said plurality of rods form a plurality of clusters, wherein each of said clusters is formed of a pair of said rods and each of said clusters is spaced apart from adjacent clusters about said outer peripheral surface of said inner rings.

16. The drive sprocket as recited in claim 1 , wherein said rods are cylindrically shaped having a circumferential surface.

17. The drive sprocket as recited in claim 16 , wherein a portion of said circumferential surface of said rods extends radially outward away from said outer peripheral surface of said interior ring relative to said rotational axis of said drive sprocket.

18. The drive sprocket as recited in claim 16 , wherein a portion of said circumferential surface of said rods extends radially outward away from said outer peripheral surface of said exterior ring relative to said rotational axis of said drive sprocket.

19. The drive sprocket as recited in claim 16 , wherein a portion of said circumferential surface of said rods extends radially outward away from said outer peripheral surface of said intermediate ring relative to said rotational axis of said drive sprocket.

20. The drive sprocket as recited in claim 1 , wherein an adapter is fixed to said outer guide ring of said interior ring, wherein said adapter is configured to be directed toward said tracked vehicle when said drive sprocket is mounted on said tracked vehicle.

21. The drive sprocket as recited in claim 1 , wherein a spoke assembly fixed to an outer guide ring of said interior ring; said spoke assembly is configured to be directed away from said tracked vehicle when said drive sprocket is mounted on said tracked vehicle; said spoke assembly has a plurality of spokes projecting toward the radial periphery of said drive sprocket; said spokes form an acute angle with respect to said outer guide ring.

22. The drive sprocket as recited in claim 21 , wherein each of said spokes has a ring end, a distal end, and an intermediate position located between said ring end and said distal end; said exterior ring is fixed to said distal end of said spokes and said intermediate ring is fixed to said spokes at said intermediate position.
