ABSTRACT:
An electromagnetic clutch device for transmitting torque from an input means to an output means. The clutch actuating means includes an electromagnetic winding, a driving plate, an armature coaxially disposed with the input means and threadedly connected to a driving friction ring member, said armature responsive to said electromagnetic winding and said friction ring member being allowed to advance on said armature for driving the ouput means. The relative rotational motion between the armature and the driving friction ring member causes the friction ring member to advance on the thread until full engagement with the drive output means is attained. The relative position between the armature and the driving friction ring member is maintained by a retarder disposed between the armature and the driving plate. The retarder permits relative rotational motion between the driving friction ring member and the armature in one direction and prevents relative motion between said armature and ring member in the other opposite direction.
