ABSTRACT:
An endless drive track for use on a track vehicle such as a bulldozer includes a plurality of polymeric endless track drive members, each drive member including a first lateral frictional drive face sloping inwardly with respect to a transverse direction of the endless drive track at a first angle with respect to horizontal and a second lateral frictional drive face sloping inwardly with respect to the transverse direction of the endless drive track at a second angle with respect to horizontal, and a reinforcement member for connecting the drive members to one another to form an endless track. Each drive member of the endless track preferably includes first and second lateral frictional drive faces sloping inwardly toward one another at the first angle with respect to horizontal and third and fourth lateral frictional drive faces, above the first and second drive faces, sloping inwardly toward one another at the second angle with respect to horizontal, the second angle being greater than the first angle. The endless drive track preferably is utilized with a drive wheel which has drive surfaces sloped and shaped to match the lateral frictional drive faces of the drive members.
