ABSTRACT:
A trailer coupling is provided with a sliding plate and a coupling plate having an anti-friction layer, preferably of a PTFE composite material. To make it possible that in operation the anti-friction surface always remains paired with the same counter surface so that they may matingly wear with each other, a steel plate is placed onto the king journal of the tractor covering the slide plate itself. The steel plate is finished to a depth of roughness of 1 .mu.m. The bore of the steel plate permits passage of the king journal without additional clearance, so that the steel plate is maintained in position by tilting and no further connection is necessary between the steel plate and the slide plate.
