Abstract
A track assembly for traction of an off-road vehicle, such as an all-terrain vehicle (ATV) or a snowmobile, is disclosed. The track assembly comprises a plurality of track-contacting wheels, which comprises: a drive wheel; and a plurality of idler wheels spaced apart in a longitudinal direction of the track assembly. The track assembly also comprises an endless track disposed around the track-contacting wheels. A frame of the track assembly may comprise a hollow frame structure. The hollow frame structure may be dimensioned to impede accumulation of snow, mud, rocks, debris, etc. in the track assembly. The track assembly may comprise interwheel guides between longitudinally adjacent ones of the idler wheels to contact a bottom run of the endless track, and/or fenders adjacent to given ones of the idler wheels. The frame's hollowness, the interwheel guides, and/or the fenders may be realized during molding of a portion of the frame using a blow molding or other fluid-based molding process.
