ABSTRACT:
A device for controlling the return of the coupling head for central couplings to their central position, especially for use in connection with rail vehicles, in which the coupling head is by means of a coupling rod linked to a housing arranged on a vehicle. A cam operatively connected to the coupling rod extends between two abutments which in the horizontal path of the cam are displaceable hydraulically, electrically or pneumatically. In one end position of the abutments, the full horizontal lateral deviation of the coupling rod is available, whereas in the other end position, the cam is clamped in between the two abutments.
