An electromagnetic frictionally engaged clutch for arranging inside a drive train connecting a drive motor and a vehicle door or flap. The arrangement ensures that the vehicle door is securely held in each intermediate position, when the clutch is in an idle state, while maintaining the possibility of a manual emergency actuation of the vehicle door. The rotor includes at least one permanent magnet in addition to the electric coil, such that when a current does not pass through the coil, the armature disk is pressed against the friction lining of the rotor, with a force which is strong enough for the vehicle door or vehicle flap to securely remain in position occupied when the clutch is an idle state, and for the friction engagement between the armature disk and the friction lining to be overcome when the vehicle door or vehicle flap is subsequently manually actuated.

Electromagnetic frictionally engaged clutch and method for operating the same

A device having a drive () for pivoting a vehicle door or vehicle lid rotationally connected to a hinge bow () around a hinge axle (). In order to build the device () in a compact manner, wherein no special reinforcement of the hinges of the vehicle door or vehicle lid is required for utilization of the device () in compliance with regulations, a drive () is provided with a drive shaft () that is arranged in an extension of the hinge axle, the drive shaft () being connected to a bow-shaped drive lever () that is arranged parallel to the hinge bow () and that can be fixed to the hinge bow ().
