ABSTRACT:
A power transfer mechanism incorporated in a multiple path drive system comprises a transfer case disposed between a source of input torque and a pair of drive axles. Torque is transferred directly to one drive axle and is transferred automatically to the other drive axle through a double-acting roller clutch when required. The transfer case is constructed such that it may be assembled in two configurations; one in which the output shafts are coaxial and offset from the input shaft, and the other in which the input shaft and one output shaft are coaxial, the other output shaft being offset therefrom.
