Abstract

A drive sprocket for driving a track of a utility track vehicle is provided. The drive sprocket includes a pair of spaced-apart inner rings having a spacer fixedly attached between the inner rings. An adapter is attached to an outwardly-directed surface of one of the inner rings. A plurality of rods are attached in a spaced-apart manner about the outer peripheral edge of the inner rings. A guide ring is attached to each end of the rods in a perpendicular manner, wherein the guide rings are substantially parallel to the inner rings.

First claim

What is claimed is:

1. A drive sprocket for driving a track of a tracked utility vehicle, said drive sprocket comprising:
a pair of spaced-apart inner rings, wherein said inner rings are oriented in a substantially spaced-apart manner, each of said inner rings having a peripheral edge;
a plurality of rods attached to said inner rings adjacent to said peripheral edge thereof, said rods having a surface; and
a pair of guide rings fixedly attached to said rods, wherein each of said guide rings is attached adjacent to an opposing end of said rods, said guide rings being oriented substantially parallel to each other and said inner rings;
wherein a portion of said surface of said rods extend radially outward away from an outer peripheral surface of the inner rings relative to a rotational axis of said drive sprocket.

2. The drive sprocket of claim 1 further comprising a spacer positioned between said inner rings, said spacer being fixedly attached to said inner rings.

3. The drive sprocket of claim 1 further comprising an adapter attached to an outwardly-directed surface of one of said pair of inner rings.

4. The drive sprocket of claim 1 further comprising a slide ring attached to an outwardly-directed surface of each of said guide rings.

5. The drive sprocket of claim 1 , wherein an outwardly-directed surface of each of said guide rings is coated with a friction-reducing material.

6. The drive sprocket of claim 1 , wherein each of said plurality of rods is spaced-apart from adjacent rods.

7. The drive sprocket of 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 cluster is spaced-apart from adjacent clusters about said peripheral edge of said inner rings.

8. The drive sprocket of claim 1 , wherein said rods are cylindrically shaped having a circumferential surface.

9. The drive sprocket of claim 8 , a portion of said circumferential surface of said rods extend radially outward away from an outer peripheral surface of the guide rings relative to a rotational axis of said drive sprocket.

10. A drive sprocket for driving a track of a tracked utility vehicle, said drive sprocket comprising:
a pair of spaced-apart inner rings, wherein said inner rings are oriented in a substantially spaced-apart manner, each of said inner rings having a peripheral edge;
a plurality of rods attached to said inner rings adjacent to said peripheral edge thereof, said rods having a surface; and
a pair of guide rings fixedly attached to said rods, wherein each of said guide rings is attached adjacent to an opposing end of said rods, said guide rings being oriented substantially parallel to each other and said inner rings;
wherein a portion of said surface of said rods extend radially outward away from an outer peripheral surface of the guide rings relative to a rotational axis of said drive sprocket.

11. The drive sprocket of claim 10 further comprising a spacer positioned between said inner rings, said spacer being fixedly attached to said inner rings.

12. The drive sprocket of claim 10 further comprising an adapter attached to an outwardly-directed surface of one of said pair of inner rings.

13. The drive sprocket of claim 10 further comprising a slide ring attached to an outwardly-directed surface of each of said guide rings.

14. The drive sprocket of claim 10 , wherein an outwardly-directed surface of each of said guide rings is coated with a friction-reducing material.

15. The drive sprocket of claim 10 , wherein each of said plurality of rods is spaced-apart from adjacent rods.

16. The drive sprocket of claim 10 , 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 cluster is spaced-apart from adjacent clusters about said peripheral edge of said inner rings.

17. The drive sprocket of claim 10 , wherein said rods are cylindrically shaped having a circumferential surface.

18. The drive sprocket of claim 17 , a portion of said circumferential surface of said rods extend radially outward away from an outer peripheral surface of the inner rings relative to a rotational axis of said drive sprocket.

19. The drive sprocket of claim 10 , wherein a portion of said surface of said rods extend radially outward away from an outer peripheral surface of the inner rings relative to a rotational axis of said drive sprocket.

20. A drive sprocket for driving a track of a tracked utility vehicle, said drive sprocket comprising:
a pair of spaced-apart inner rings, wherein said inner rings are oriented in a substantially spaced-apart manner, each of said inner rings having a peripheral edge;
a plurality of rods attached to said inner rings adjacent to said peripheral edge thereof, said rods having a surface; and
a pair of guide rings fixedly attached to said rods, wherein each of said guide rings is attached adjacent to an opposing end of said rods, said guide rings being oriented substantially parallel to each other and said inner rings;
wherein a portion of said circumferential surface of said rods extend radially outward away from an outer peripheral surface of the inner rings relative to a rotational axis of said drive sprocket, and/or a portion of said circumferential surface of said rods extend radially outward away from an outer peripheral surface of the guide rings relative to a rotational axis of said drive sprocket.
