Abstract
Abstract A ring gear of a differential connected to an engine, and a sun gear and a planetary carrier are connected to left and right output shafts of the differential. A first pinion and a second pinion integrally formed and having different circle radii are carried on a carrier member which is rotatably fitted over the left output shaft. The first pinion is connected to the right output shaft, while the second pinion is connected to the left output shaft. When a hydraulic clutch is brought into an engaged state during clockwise turning of a vehicle, the carrier member is decelerated to accelerate a left front wheel, and a torque is transmitted to the left front wheel. When a hydraulic clutch is brought into an engaged state during counterclockwise turning of a vehicle, the carrier member is accelerated to accelerate a right front wheel, and a torque is transmitted to the right front wheel.
