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

FIELD: machine building.

SUBSTANCE: invention relates to differential mechanisms with locking devices. In the symmetrical differential, the locking device is designed in the form of a vane reversible hydraulic pump including a stator, a rotor, blades with springs, distribution disk, cover, check valves and suction, discharge and outlet 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 inverted from the bottom to a back valve, with a through center hole in its center, a return compression spring, and a cylindrical pin rigidly fixed in the differential housing coaxially fixed within the housing of the differential pin.

EFFECT: blocking properties of differential are increased.
