ABSTRACT:
A torque distribution deciding control unit, a planetary gear device as a central differential and an oil hydraulic clutch having opposite disks are provided on a motor vehicle. The clutch is disposed between output members of the planetary gear device, whereby torque is transmitted to front and rear wheels at a distribution ratio decided by clutch torque of the clutch. The control unit operates the clutch so as to distribute the torque at a ratio in accordance with slipping of the front or rear wheels with respect to each other so as to reduce the torque for the slipping wheels.
