Abstract
The invention relates to an electromagnetic friction clutch for arrangement within a drive train connecting a drive motor and a vehicle door. The vehicle door is reliably held in any intermediate position when a clutch is disconnected. To preserve the ability to carry out a manual emergency actuation of the vehicle door, a compression spring is provided acting upon an armature disk of the clutch in the axial direction in such a way that, with the clutch in the disconnected state, the armature disk is pressed against the frictional lining of a rotor part with a force which is sufficient to ensure that the vehicle door remains reliably in position. During a subsequent manual actuation of the vehicle door, the frictional connection between armature disk and frictional lining can be overcome.
