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 the fixed axle and is transferred automatically to the steering axle through a double-acting overrunning clutch when required. The clutch is biased to advance toward one engaged position, but is prevented from locking by a direction-sensitive latch so long as a normal overrunning condition is present.
