<p>A drive wheel (12) is provided for mounting on a rotatable axle of a vehicle for driving a continuous flexible track (15). The flexible track (15) includes an inner surface (28) having a plurality of lugs (32) and terminating at terminal surfaces (32a). The drive wheel (12) includes a central hub mountable on the axle of the vehicle for rotational movement therewith. First sidewall (20) and second sidewall (22) extend radially from the central hub and an outer rim (24) interconnects the radial outer edges of the sidewalls (20 and 22). It is intended that the terminal surfaces (32a) of the lugs (32) engage the outer rim (24) of the drive wheel (12) such that the lugs (32) are supported when the flexible track (15) is driven by the drive wheel (12).</p> |
