Selectively actuated transfer case

摘要

A transfer case for use in motor vehicles for transferring drive torque from a powertrain to first and second drivelines includes a first output shaft that is connected to the powertrain of the vehicle and is adapted to transmit drive torque from the powertrain to the first driveline. A second output shaft is adapted to transmit drive torque to the second driveline, and a transfer clutch is adapted to transfer drive torque from the first output shaft to the second output shaft. A ball screw assembly is adapted to actuate the transfer clutch.
