ABSTRACT:
To realize a small-sized differential gear provided with both differential limiting and locking functions simultaneously without markedly modifying the conventional differential case, the differential gear comprises a differential mechanism having a differential case, pinion shafts, pinion gears, two side gears, etc.; two frictional multiplate clutches disposed between the two side gears and two inner side wall surfaces of the differential case, respectively for limiting differential function; a lock clutch disposed within the differential case for generating two opposite direction thrust forces to engage said limit multiplate clutches into engagement and further locking the differential function; and actuator for actuating the lock clutch from outside of the differential case.
