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).

Connecting elements for crawler track vehicle chains constructed pursuant to the dually-hinged pin principle, wherein the connector is arranged interiorly of the chain members. The connectors consists of two clamps each having arms which can be inserted offset into each other, and which are fastenable by means of screw connection to the link pins of adjacent chain link members, each clamp encompassing respectively one link pin and form-fittingly fixed thereto, the link pin having a cross-section in at least the region of the connectors deviating from a circular cross-section, and wherein the clamps lockingly interengage in each other.

In hinge tracks with rubber mountings (5) in which rubber-lined tubular steel bushes mount track pivot pins (20), the pin ends are usually provided with screwthreaded projection portions so that the steel bushes (10) are motion-free braced relative to each other and relative to the track pivot pins (20) by means of nuts. In order to improve the useful life of the rubber mounting (5) and reduce maintenance, a rubber-lined spreadable bush (10) with at least one dividing gap (11) is proposed instead of the tubular bush. The internal width (25) of the bush (10) which is pressed into position is less than the diameter (27) of the track pivot pin (20). The inserted track pivot pin (20) expands the bush (10) which is pressed into the chain link member (1). In that case the track pivot pin (20) is braced in the bush (10) and is fixed in its longitudinal direction by frictional engagement and in the peripheral direction by frictional engagement and/or positively locking engagement. The screw for bracing the bushes (10) are eliminated and an increase in the rubber mounting surface is achieved by virtue of using the screwthread space of the screwthread arrangement. That affords an increased service life for the rubber mounting in a maintenance-free design configuration.
