Abstract: A transfer case comprises a primary output shaft, a secondary output shaft, a clutch, and a plurality of valves. The primary output shaft includes a hub rotationally coupled thereto. The clutch selectively couples the primary output shaft to the secondary output shaft to transfer torque therebetween. The clutch includes a housing, interleaved plates, and an apply plate. The housing is rotationally coupled to the secondary output shaft. The interleaved plates alternate between a first subset of the interleaved plates rotationally coupled to the hub and a second subset of the interleaved plates rotationally coupled to the housing. The apply plate compresses the interleaved plates for transferring torque between the hub and the housing. The valves selectively release oil supplied through the primary output shaft into the housing. Each valve includes a bore formed in the hub and a valve rod movable by the apply plate to open the valve.

Abstract: An electric drive unit for a powertrain system including first and second drivelines and a primary propulsion system for translating rotational torque to the first driveline. A motor acts to generate rotational torque and a pinion is disposed in selective communication therewith. A differential is interposed between the pinion and the second driveline of for splitting torque therebetween. A first planetary is disposed between the motor and pinion, and a second planetary is disposed between the first planetary and pinion. A dog clutch interposed between the pinion and the planetaries is movable between a first position wherein torque from the motor is translated through the first planetary and the dog clutch to drive the second driveline at a first drive ratio, and a second position wherein torque from the motor is translated through both planetaries and the dog clutch to drive the second driveline at a second drive ratio.
