ABSTRACT:
An electromagnetic clutch assembly for motor vehicle transfer cases and the like includes an electromagnetic operator and a disc pack clutch assembly disposed on opposite sides of a chain drive sprocket. The clutch pack assembly is driven by a primary output shaft of the transfer case and transfers energy to the chain drive sprocket and thence to a secondary output shaft. The disc pack clutch assembly is actuated by the clutch operator which generates a compressive force which is transferred to the clutch pack assembly by a plurality of axially disposed pins received within complementary passageways in the chain drive sprocket. A multiple position clutch collar selectively: allows the clutch pack to free-wheel by fully disengaging it from the primary output shaft, couples the input of the disc pack clutch assembly to the primary output shaft to permit on-demand clutch operation and torque distribution and couples or locks the input and output members of the disc pack clutch assembly together and provides nominally equal torque delivery to the primary output shaft and the chain drive sprocket and secondary output shaft.
