Abstract:
1. 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 differential driven by said input shaft and having first and second output; a first drive mechanism connecting said first output to the first driveline; a second drive mechanism connecting said second output to the second driveline; a mode clutch having a first member supported for rotation relative to said first output and a second member coupled to said second output, 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 and said mode clutch is 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 first output and operable in a second mode to release said first member from coupled engagement with said first output; 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 second mode and said disconnect clutch into its second mode and said shift mechanism is operable in its second position to shift said mode clutch into first mode and said disconnect clutch into its first mode.
