CONE SELF-LOCKING DIFFERENTIAL WITH HYDRAULIC RESISTANCE Russian patent published in 2017 - IPC F16H48/27 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to self-locking differentials with hydraulic resistance. Cone self-locking differential comprises a casing, side gears entered into engagement with the satellites, and a locking device. The locking device is designed as a reversible pump, comprising a stator, rotor, blades with springs, distributing disk, cover, check valves and the suction, pressure and outlet channels . The locking device has two differential lock valves mounted in front of the check valves in axial holes between radial pressure stator channels and output channels, each of these valves consists of a piston stator with a bottom facing the radial pressure channel and a return spring, and a piston axial bore intersects the outlet channel. The piston which has a diameter larger than the outlet channel diameter, can overlap the outlet channel.

EFFECT: self-locking differentials with hydraulic resistance, with enhanced blocking properties.
