MECHANISM OF DIFFERENTIAL LOCK (VERSIONS) Russian patent published in 2012 - IPC F16H48/20 

FIELD: machine building.

SUBSTANCE: mechanism of differential lock comprises a case (1) of the lock mechanism fixed by bolts (2) on a case (3) of the unit. In the case (3) there is a shaft (6) of a front axle drive. At the right side of the shaft (6) of the front axle drive on splints there is a coupling (10) of differential lock, which engages with a carrier (11) of differential. In the case (1) of the lock mechanism there is a sensor (14) of lock switching, with the help of a stem (15) joined with a fork (13) in a transfer gearbox (version 1) or directly with the stem (15) in driving axles (version 2). The fork (13), coupled with a coupling (10) of differential lock, is installed on the stem (15), arranged as a whole with a piston (16). The piston (16) is pressed with a return spring (17) and is installed in a body (18) of the differential lock mechanism. The body (18) of the differential lock mechanism is installed into a hole of the case (1) of the lock mechanism in the transfer gearbox (version 1) or in the case (3) in driving axles (version 2). The piston (16) rests against an adjustment nut (21) with external thread. A cover (23) of the lock mechanism is fixed to the case (1) of the lock mechanism with bolts (24) and has a hole (25) for compressed air supply.

EFFECT: improved operational properties of a device.
