ABSTRACT:
An armature is attracted to an electromagnetic field and moves axially of a rotary shaft when the field is excited. As the armature moves toward the field, it causes a movable pressure plate to shift along the shaft toward a fixed pressure plate and to press the discs of a disc pack into frictional engagement with one another. The disc pack is located between the two pressure plates and, when the discs are pressed into frictional engagement, they transmit torque from the shaft to an output member. The movable pressure plate is splined to the shaft and is tied rigidly to the armature to prevent the armature from cocking relative to the shaft.
