ABSTRACT:
The rotation of a first rotating element is shifted in speed by a speed shift device, and is transmitted to a second rotating element or a third rotating element of a differential device via a first clutch or a second clutch. In this manner, the torque of right and left driving wheels can be controlled. Furthermore, in conjunction with limitation of the differential motion, the amount of torque transmitted to a fourth rotating element is eliminated by allowing the speed shift device to freely rotate, and the accumulated amount of sliding of friction engagement elements at the time of differential motion limitation can be reduced by completely engaging the first clutch and the second clutch without allowing them to slide. Thus, the differential motion limitation control can be realized without a need to increase the size of the first clutch and the second clutch.
