FIELD: machine building.
SUBSTANCE: invention relates to differential mechanisms with hydraulic blocking devices. Self-regulating differential contains side gears with spider pinions and a locking device. Locking device is composed of the vaned reversible hydropump with the stator, rotor, vanes with springs, distribution disc, cover, check valves, suction, delivery and discharge channels. Locking device has two differential lock valves, each of which consists of a piston facing the bottom to back-pressure valve with a through hole, a return spring of compression and a two-stage cylindrical pin coaxially arranged within this return spring.
EFFECT: blocking properties of differential are increased.
