Abstract
A final reduction gear comprising a pair of bevel gears are provided between a rear drive shaft and a rar axle shaft. A pair of oil hydraulic clutches are provided on both ends of the rear axle shaft for transmitting output of the final reduction gear to rear wheels of a motor vehicle respectively. Pressure of oil appplied to each of the clutches is controlled in accordance with driving conditions of the vehicle thereby controlling transmitting torque capacity of each clutch at cornering.
