ABSTRACT:
Locking arrangements (40,44) are respectively connected, for joint rotation, to a driving and a driven hub (10,16) which are mounted for rotation in relation to one another. The two locking arrangements (40,44) can be coupled to one another by at least one detent member (42) which, in an engaged position, produces an axial disengaging force (B) depending on the transmitted torque. A loading device is provided to produce an engaging force (C) which can be overcome by the disengaging force (B) if a certain torque is exceeded. This stressing device comprises a cylinder compartment (36) to which a fluid under pressure can be supplied from an inlet (56) so long as the detent member (42) is engaged. The detent member (42) is connected to a distributing slide valve (32) for joint axial displacement, which distributing slide valve separates the cylinder compartment (36) from the inlet (56) and connects it to a relief passage (76) if the detent member (42) is at least partially disengaged.
