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

FIELD: instrument engineering.

SUBSTANCE: invention relates to hydraulic differential mechanisms with locking devices. In the inter-wheel differential containing the semi-axial gears with satellites and the locking device made in the form of a paddle reversible hydraulic pump. Pump includes a stator, rotor, blades with springs, distribution disk, cover, back-pressure valves and suction, discharge and outlet channels. Locking device has two differential lock valves installed after the back-pressure valves, each of which consists of a piston with a through axial coaxial tapered bore, a return compression spring and coaxially fixed within the return spring of the cylindrical pin rigidly fixed in the roll pin.

EFFECT: high efficiency is achieved.
