摘要

A drive wheel mounted on a rotatable axle of a vehicle is provided for driving a continuous flexible track. The drive wheel includes a central hub mountable on the axle for rotational movement therewith. First and second rim walls extend radially from the central hub and define a circumferentially extending void in the drive wheel. A plurality of circumferentially spaced rollers are rotatably supported in the void for engaging a portion of the track.
