ABSTRACT:
A transfer case includes a clutch assembly having both a disc pack clutch and cone clutch disposed in mechanical parallel between the main transfer case shaft and secondary output shaft. The disc pack clutch includes a plurality of interleaved discs and an electromagnetic operator which effects compression of the clutch pack to transfer torque from the main transfer case shaft to a chain drive sprocket, through a chain, to the secondary output shaft. The cone clutch is disposed adjacent the disc pack and is also actuated by the electromagnetic operator. One of the cone clutch elements is driven by the main transfer case shaft and the other cone clutch element provides power to the drive chain and, in turn, to the secondary output shaft. Preferably, the other cone clutch element is integrally formed with the chain drive sprocket.
