Abstract

A transfer case for selectively coupling a secondary driveline with a primary driveline comprises: a first output shaft; a second output shaft; a clutch assembly disposed at the second output shaft, the clutch assembly including inner and outer drum members, one of the inner and outer drum members rotatable in association with rotation of the first output shaft and the other one of the inner and outer drum members coupled with the second output shaft, the clutch assembly further including a plurality of frictional clutch plates, the frictional clutch plates formed of at least one frictional clutch plate coupled with the inner drum member and at least one frictional clutch plate coupled with the outer drum member; an actuator shaft rotatably coupled with an actuator; and a clutch actuator means coupled with the actuator for applying axial force to the frictional clutch plates to transmit a drive torque of the first output shaft to the second output shaft. The clutch actuator means can be a pivot lever pivotally moveable in association with rotation the actuator shaft coupled with the actuator for said applying the axial force to the frictional clutch plates, or can be a sliding lever moveable in an axial direction of the actuator shaft in association with rotation the actuator shaft coupled with the actuator.
