Track assembly for an all-terrain vehicle (ATV) or other tracked vehicle

摘要

A track assembly for providing traction to an all-terrain vehicle (ATV) or other tracked vehicle. The track assembly may comprise a wheel device for contacting an inner side of an endless track such that a longitudinal end segment of the endless track turns around the wheel device. The wheel device allows a change in curvature of the longitudinal end segment of the endless track when the longitudinal end segment of the endless track contacts an obstacle on the ground. In some embodiments, the wheel device may comprise a resilient wheel that is elastically deformable. In other embodiments, the wheel device may comprise a wheel carrier carrying a plurality of carried wheels.

主权项

1. A track assembly for providing traction to a vehicle on a ground surface, the track assembly being mountable to an axle of the vehicle and comprising:
a) an endless track comprising a ground-engaging outer side for engaging the ground surface and an inner side opposite to the ground-engaging outer side; and b) a track-engaging arrangement for driving and guiding the endless track, the endless track being disposed around the track-engaging arrangement, the track-engaging arrangement comprising:
i. a drive wheel for driving the endless track when the axle of the vehicle rotates; andii. a plurality of idler wheels which includes a leading idler wheel and a trailing idler wheel spaced apart in a longitudinal direction of the track assembly and contacting a bottom run of the endless track; wherein: each idler wheel of the plurality of idler wheels is resilient and comprises foam; the inner side of the endless track comprises a plurality of wheel-contacting projections for contacting at least one of the drive wheel and the plurality of idler wheels; and a width of the idler wheel in a widthwise direction of the track assembly is greater than a dimension of a given one of the wheel-contacting projections in the widthwise direction of the track assembly.
