FIELD: machine building.
SUBSTANCE: invention relates to hydraulic differential mechanisms with locking devices. Differential contains side gears with spider pinions and a locking device. Locking device is designed as a reversible hydraulic pump including a stator, a rotor, blades with springs, a distributing disk, a cover, check valves and suction, discharge and output channels. Locking device has two differential lock valves, each of which consists of a piston with a through hole, a return spring of compression and a two-stage cylindrical pin coaxially arranged within this return spring.
EFFECT: increase in the blocking properties of the differential is achieved.
