ABSTRACT:
A power transmission apparatus having an input shaft connected, by planetary gearing, to two coaxially arranged output shafts. The planetary gearing permits differential rotation between the output shafts. A limiting device located between the output shafts to limit the differential rotation thereof. The limiting device includes a clutch member mounted on the first output shaft and alternating first and second clutch plates. The first plates are axially movable relative to and rotatably fixed to the clutch member, and the second plates are axially movable relative to and rotatably fixed to the second output shaft. An interengaging cam mechanism is carried on the clutch member and the first output shaft, and arranged such that upon relative angular movement between the clutch member and the first output shaft, the clutch member is moved axially to frictionally engage the first and second clutch plates.
