Abstract: The claimed invention relates to the automotive industry, namely: to devices for locking differentials of vehicle driving axles with forced locking. The technical result is creating a differential locking mechanism facilitating a significant improvement of performance indicators in differentials using the claimed locking mechanism and the range expansion of such a differential use. The technical result is achieved by the locking device integrated into the differential, comprising the differential housing, semi-axle gears located inside the housing, and being in either “Locked” or “Unlocked” positions, consists of: locking elements shaped as a rotation body; through locking holes made in the differential housing; the recesses of semi-axle gear arranged on the semi-axle gear surface; ring lock-up clutch on the differential housing around the locking holes with locking elements, on the inner surface of which there are lock-up clutch grooves enlarging the contact spot area: “Lock-up clutch—locking element”.
