ABSTRACT:
A lockable differential gear for motor vehicles in which the locking mechanism includes a lamellae set adapted to be actuated from the outside by an annular piston. The differential gear of the invention is so constructed that the forces are not guided by way of the radial bearing between the differential housing and the transmission housing when the locking mechanism is actuated. This is achieved by additional axial bearings. The force flow is thereby introduced in one embodiment by way of a separate transmission member. In other embodiments, the force flow proceeds by way of a wheel output shaft and finally in still another embodiment, the force flow is transmitted inside of the differential housing.
