ABSTRACT:
A central differential for splitting output torque of a transmission is formed by a complex planetary device. The planetary device comprises an input sun gear operatively connected with an output shaft of the transmission, a plurality of output sun gears, a carrier, and a pinion member comprising a plurality of planetary pinions integral with each other and rotatably supported on the carrier. Fluid operated friction clutches are provided for selectively connecting one of the output sun gears to an output member of the central differential.
