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 .
