Abstract
A power transfer mechanism incorporated in a multiple path drive system comprising a transfer case disposed between a source of input torque and a pair of drive axles. In one mode, torque is transferred directly to one drive axle and automatically to the other drive axle through a double-acting overrunning clutch when required. In another mode, torque is transferred to both drive axles in a locked-up condition.
