DEVICE FOR MANAGING DIFFERENTIAL BLOCKING Russian patent published in 2018 - IPC F16H48/30 B60K23/08 B60K17/16 

FIELD: machine building.

SUBSTANCE: invention relates to differential lock control systems. Control system comprises crankcase (1) with a differential and hydro-clutch lock (4) located therein, hydraulic cylinder (7) connected to pneumatic chamber (8), electromagnetic control, made in the form of electromagnetic valves (19, 20, 21), sensors (22, 23). Pneumatic chamber (8) and hydraulic cylinder (7) are combined into one housing (9). Sub-piston cavity of hydraulic piston (11) is provided with shut-off and check valve (14, 15) connected to locking cylinder (16) and to the oil pan of crankcase (1), respectively. Sub-piston cavity of pneumatic piston (10) is provided with limit switch (18) connected to solenoid valves (19, 20, 21) and with sensors (22, 23) mounted on output shafts (3) of the differential. Movement of pistons (10, 11) is limited by stop (13).

EFFECT: simplifies the design and increases the reliability of the lock.
