ABSTRACT:
A differential gear includes a differential case having a plurality of recesses provided circumferentially at equal intervals, a plurality of pinions and a pair of side gears respectively disposed in the differential case, shafts connected to the respective side gears and a sleeve supported by one shaft shiftably in an axial direction thereof and unrotatably relative thereto and having a plurality of claws capable of fitting in the recesses. A controlling device includes a cylinder unit for operating the sleeve, a pressure sensor for detecting the braking condition of a vehicle, a sensor for detecting a steering angle and a controller for receiving signals from both sensors and controlling the cylinder unit to limit the rotational speed differential generated from the the differential gear when the vehicle is braked and turned with a steering angle exceeding a predetermined value.
