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. Torque is transferred directly to one drive axle and is transferred automatically to the other drive axle through a double-acting overrunning clutch when required. The clutch is biased toward one engaged position, and is prevented from locking inadvertently in the other engaged position by a centrifugal blocking device.
