ABSTRACT:
An electromagnetic clutch assembly adapted for use in actuating a refrigerant compressor having a drive shaft with a continuously driven pulley rotatably supported about the drive shaft. An armature plate is supported in spaced parallel relationship from the pulley friction plate by an elastomeric torque cushion which extends between the drive shaft and the armature plate. The elastomeric torque cushion is capable of flexing to allow the armature plate to bridge the gap under the influence of an electromagnetic force to engage the pulley friction plate thereby translating power from the pulley to the drive shaft. The torque cushion includes at least one reinforcing member disposed within the cushion for preventing the torque cushion from buckling as torque is translated from the pulley through the armature plate and the torque cushion to the drive shaft.
