Coupling unit for connection of trailer to towing vehicle has operating assembly connected to locking device for moving operating component from working position into released position synchronously with shift of coupling pin

摘要

The coupling unit has an operating assembly (17) for the coupling pin (10) and is mechanically connected to a locking device (22) for moving the operating component from the working position into a released position synchronously with shift of the coupling pin from the working position into the released position following operation of the operating assembly. The locking assembly has a locking element (23) with a spherical body which overlaps the head section (14) of the coupling pin. Independent claims are included for a coupling pin and for a deflection lever for a coupling unit for hitching up a trailer to a towing vehicle.
