ABSTRACT:
A power transfer mechanism incorporated in a multiple path drive system comprising a source of input torque, a transfer case, and a pair of drive axles having equal axle ratios. Torque is transferred directly to the first drive axle and, when required, is transferred automatically to the second drive axle through a path including a freewheel device. Another path is provided in parallel with the freewheel device for torque transfer from the second drive axle to the first drive axle.
