ABSTRACT:
A shaft 12 is secured to and is rotatable with a wheel hub of a vehicle. A sprocket wheel 22 is secured to and rotates with the shaft 12 and has evenly spaced apart, tooth-receiving sockets 28 at its periphery. The shaft 12 is mounted on the upper portion of a track supporting frame 42 by a pillow block mount 52 on each side of the sprocket wheel 22. Each mount 52 has housed within it bearing means 54 surrounding the shaft 12. Idler wheels 44 are mounted on the lower portion of the frame 42. An endless track 82 extends about the sprocket wheel 22 and the idler wheels 44. The track 82 has a multiplicity of radially inwardly projecting drive teeth 84 that roll into and out from the sprocket wheel sockets 28 when the vehicle is operated. The drive teeth 84 are of sufficient depth to prevent disengagement of the track 82 from the sprocket wheel 22. The track 82 includes a multiplicity of transverse segments 86 secured together by at least one endless belt 94.
