Abstract
A limited slip differential comprises a pair of friction clutches interposed between a pair of pressure rings and a differential casing. The friction clutches are urged toward an engaged condition to reduce a differential action when a pinion mate shaft having a pair of cam portions rotate to urge the pressure rings to move away from each other. The friction clutches are also urged toward the engaged condition to reduce the differential action when supplied with fluid pressure from a hydraulic system. The hydraulic system controls supply and discharge of fluid pressure to and from said friction clutches in view of running conditions of the vehicle, such as for example accelerated conditions.
