GEAR DIFFERENTIAL Russian patent published in 2018 - IPC F16H48/27 

FIELD: machine building.

SUBSTANCE: invention relates to differential mechanisms with locking devices. In the gear differential, the locking device is composed of the reversible hydropump with a stator, rotor, vanes with springs, distribution disc, cover, check valves, suction, delivery and discharge channels. Locking device has two differential lock valves installed after the check valves in the axial parts of the output channels. Each valve consists of a piston with axial grooves of a semicircular section located on its lateral cylindrical surface along its height, and a return compression spring installed in the coaxial hole following the hole for the piston. This piston on the right along the height of the axial grooves of the semicircular section has a conical chamfer, and the bottom of the hole for the piston has a corresponding conical surface.

EFFECT: blocking properties of differential is increased.
