A track assembly for a reduced-size vehicle (e.g., an all-terrain vehicle) designed primarily for off-highway usage, over undeveloped roads or other unprepared surfaces, steerable by changing an orientation of the track assembly by a steering mechanism of the vehicle, which comprises an endless track and a plurality of wheels for supporting and driving the endless track. The plurality of wheels includes a leading idler and a trailing idler and a segment of the endless track extending between the leading and the trailing idlers defines a ground engaging run. The plurality of wheels also includes a drive wheel in driving engagement with the endless track for imparting movement to the endless track. The ground engaging run has a load bearing section located between the leading idler and the trailing idler, and transferring to the ground surface a major portion of the load carried by the track assembly, and having a longitudinal extent that does not exceed a diameter of the drive wheel. The ground engaging run also has a leading section extending between the leading idler and the load bearing section and oriented such as to converge toward the ground surface when the endless track is in motion and propels the vehicle and a trailing section extending between the load bearing section and the trailing idler and oriented such as to diverge from the ground surface when the endless track is in motion and propels the vehicle. A first horizontal distance between the leading idler's axis of rotation and the drive wheel's axis of rotation is different from a second horizontal distance between the trailing idler's axis of rotation and the drive wheel's axis of rotation. |
