Abstract
Novel wheel assemblies for use in track drive systems in a tracked vehicle, in support of improving uniformity of pressure distribution across the width of the track, between the track and the underlying ground surface, where track installed on the vehicle is wider than the wheel bodies which are supplied as original equipment with the tracked vehicle. Such improved uniformity of pressure is achieved by adding, to the wheels of such tracked vehicle, auxiliary wheel bodies which extend the widths of the wheels to widths more reflective of the width of the track being used in such vehicle. In cases where different track widths are sequentially employed on a given vehicle, auxiliary wheel assemblies of respective different widths can be sequentially mounted, removed, and the like to reflect the widths of the tracks being employed.
