Abstract
Between an input shaft and each of left-wheel and right-wheel axles, a speed change mechanism and a multi-plate clutch mechanism are interposed so that a rotational speed of the axle is changed (for example, increased) by a speed change mechanism and is transmitted to a hollow axle. The multi-plate clutch mechanism is interposed between the hollow axle and a differential case. By coupling the multi-plate clutch mechanism, drive torque is fed from one of the differential case and the hollow axle, said one member rotating at a higher speed, to the other member rotating at a lower speed. When the ratio .alpha. of a rotational speed of the left wheel to that of the right wheel becomes greater than the predetermined value .alpha..sub.0 and transfer of torque in a desired direction is no longer feasible. The multi-plate clutch mechanisms are hence made free. The multi-plate clutch mechanisms are controlled by a control unit.
