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. The 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 toward one engaged position and is prevented from locking inadvertently in the other engaged position by a direction-sensitive blocking device. Action of this device is timed in order to insure proper blocking. |
