ABSTRACT:
A central differential comprising a planetary gear device is parallel to front axles of a motor vehicle, and coaxially to a transfer shaft of a transfer device. The planetary gear device comprises a first sun gear connected to an output shaft of a transmission, a carrier, first and second planetary pinions integral with each other and rotatably supported on the carrier, and a second sun gear. The first planetary pinion is engaged with the first sun gear, and the second planetary pinion is engaged with the second sun gear. A fluid operated multiple-disk clutch is disposed coaxial to the central differential so as to restrict the differential operation of the planetary gear device.
