Abstract: A torque transfer mechanism is provided for controlling the magnitude of a clutch engagement force exerted on a multi-plate clutch assembly that is operably disposed between a first rotary and a second rotary member. The torque transfer mechanism includes a power-operated clutch actuator for generating and applying a clutch engagement force on the clutch assembly. Clutch actuator assembly includes a clutch apply operator for controlling the magnitude of a clutch engagement force applied to the clutch assembly. The clutch operator includes a first and second cam plate that are spaced form in one another to define a cavity therebetween. A sealing element extends between the first and second cam plates to seal the cavity between the first and second cam plates for retaining fluids in the cavity.

Abstract: A vehicle drive train for transferring torque to first and second sets of wheels includes a first driveline adapted to transfer torque to the first set of wheels and a synchronizing clutch. A second driveline is adapted to transfer torque to the second set of wheels and includes a power disconnection device and a friction clutch. A hypoid gearset is positioned within the second driveline in a power path between the synchronizing clutch and the power disconnection device. The friction clutch and the power disconnection device are positioned on opposite sides of the hypoid gearset. The hypoid gearset is selectively disconnected from being driven by the first driveline, the second driveline or the wheels when the synchronizing clutch and the power disconnection device are operated in disconnected, non-torque transferring, modes.
