Abstract: An electromagnetic frictionally engaged clutch provided with a rotor part including a friction lining. An electrical coil and a first permanent magnet are arranged on the rotor part. The clutch also includes an armature disk which is connected to a second shaft and can be displaced in a rotationally fixed manner, but axially from a coupled end position to an uncoupled end position. The coil of the clutch is enabled to be current-free both in the coupled state and in the uncoupled state. To this end, a second permanent magnet is provided for exerting an axial force opposing the magnetic force of the first permanent magnet on the armature disk.

Abstract: 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.

Abstract: A device having a drive (6) for pivoting a vehicle door or vehicle lid rotationally connected to a hinge bow (1) around a hinge axle (3). In order to build the device (5) 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 (5) in compliance with regulations, a drive (6) is provided with a drive shaft (7) that is arranged in an extension of the hinge axle, the drive shaft (7) being connected to a bow-shaped drive lever (9) that is arranged parallel to the hinge bow (1) and that can be fixed to the hinge bow (1).

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.
