Coupling system, e.g. for vehicle drive train, has mechanical pressure booster between coupling housing, pressure plate joined to coupling housing to rotate with it but move axially relative to it

摘要

The system has a friction coupling device (12e) and an actuator for introducing engagement forces into the coupling device against mechanical restoring forces. A pressure plate (16e) is or can be brought into drive connection with a first rotary shaft via a coupling housing and is joined to the coupling housing so as to rotate with it but to move axially relative to it. A mechanical pressure booster is arranged between the pressure plate and coupling housing.
