Abstract
In order to achieve as reliable a safety functioning as possible with as simple a construction as possible in the case of a trailer coupling for motor vehicles, comprising a bearing part arranged so as to be fixed on the vehicle, a ball neck which can be moved in relation to the bearing part between an operative position and a rest position and is mounted so as to be rotatable, a ball neck fixing means with form locking elements which can be transferred by way of relative movement from a fixing position into a release position and vice versa, and a mechanical positioning device, with which the relative movement of the form locking elements can be brought about for reaching the fixing position and the release position, it is suggested that form locking elements be arranged on the bearing part and form locking elements be arranged on the bearing head, that the bearing head be movable relative to the bearing part in a direction transverse to a pivoting direction in order to move the form locking elements between the fixing position and the release position, that the positioning device be adapted to be brought into a fixing position and be adapted to be brought into a release position, and that the positioning device have a force storing means which generates in the release position a restoring force which acts in the direction of a transfer into the fixing position.
