Abstract
In a vehicular driving force distribution system, an oil pump which produces a hydraulic pressure for operating a torque distribution mechanism is driven, via gears and a rotating shaft, by the rotation of a differential case of a differential device. Therefore, regardless of the rotational condition of right and left wheels, namely, even if one of the right and left wheels stops, the oil pump is driven by the driving force of the rotating differential case, thereby reliably operating the torque distribution mechanism. Also, a pump unit for housing the oil pump is supported on a partition wall that separates the differential device from the torque distribution mechanism, thereby easily supporting the oil pump.
