Electromagnetic frictionally engaged clutch for motor vehicle presses anchor disk against friction lining of rotor with force that is big enough for vehicle door to be kept in position, which is taken up when clutch is switched off

摘要

The clutch (1) includes a rotor (4) to which an electrical coil (6) and at least a permanent magnet (15) are arranged. When the coil is not flown through by current an anchor disk (10) is pressed against the friction lining (2) of the rotor with a force that is big enough for vehicle door or vehicle flap to be kept in the position that is taken up when the clutch is switched off. When the vehicle door or vehicle flap is operated manually, the friction engagement between anchor disk and friction lining is overcome. An Independent claim is also provided for a method for operating the clutch.
