Patent ID: 7004874

Claim:
A power transfer assembly for use in a motor vehicle to transfer drive torque from a powertrain to first and second drivelines, comprising: an input shaft driven by the powertrain; a first drive mechanism having a first input driven by said input shaft and a first output connected to the first driveline; a second drive mechanism having a second input and a second output connected to the second driveline; a bi-directional overrunning mode clutch having a first member supported for rotation relative to said input shaft, a second member driving said second input, and a plurality of third members located between said first and second members, said mode clutch is operable in a first mode to permit relative rotation between said first and second members in a first direction and prevent relative rotation therebetween in a second direction, said mode clutch is further operable in a second mode to prevent relative rotation between said first and second members in both directions; a disconnect clutch operable in a first mode to couple said first member of said mode clutch to said input shaft and in a second mode to release said first member from coupled engagement with said input shaft; a shift mechanism for shifting said mode clutch between its first and second modes and said disconnect clutch between its first and second modes; and an actuator for controlling movement of said shift mechanism between a first position and a second position, said shift mechanism is operable in its first position to shift said mode clutch into its first mode and said disconnect clutch into its first mode, and said shift mechanism is operable in its second position to shift said mode clutch into second mode and said disconnect clutch into its second mode.
