| 摘要 |
The invention relates to an electromagnetic friction clutch for arranging inside a transmission line, which connects a drive motor (2) and a vehicle door or cover. The aim of said invention is to permit the vehicle door to be securely fixed in each intermediate position, when said clutch (5) is in the disengaged position thereof, and also to keep the possibility of manually actuating said door in case of urgency. Said aim is achieved, whereby a pressure spring (21) acts on the armature disc (14) of said clutch in the axial direction, such that said armature disc (14), in the disengaged position of the clutch (5), is pressed by a force against the friction lining (17) of the rotor part (16), said force being strong enough so that the vehicle door securely rests in the respective position taken on the clutch (5) disengaging, and such that, on a subsequent manual actuation of the vehicle door, the frictional contact between the armature disc (14) and the friction lining (17) is surmountable. |
