Abstract
A drive system for a caterpillar track (30) comprises a drive wheel (1) with rubber-mounted drive bodies (10) fixed thereto, the drive bodies (10) engaging the guide tooth root (65) of the chain link member (52). The flank (51) of the guide tooth (32) is of a particular geometrical configuration in order to provide a long operating life for the rubber mounting means (21) of the drive body (10) by virtue of a small angle of rotational movement of the rubber casing (21).
