DEVICE FOR AUTOMATIC HYDRAULIC BLOCKING OF DIFFERENTIAL Russian patent published in 2009 - IPC F16H48/20 B60K17/16 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, particularly to lock engines of differential. Mechanism of automatic blocking of differential consists of hydraulic pump with toothed wheels, two valves, isolated in open condition by springs and intermediate shafts with intermediate toothed wheels. Mechanism of hydraulic blocking of differential is in the space between differential pinion and axle shaft gear and is enclosed into case. Toothed wheels of hydraulic pump are blocked with two intermediate toothed wheels, which are engaged with other couple of intermediate toothed wheels. Intermediate toothed wheels are blocked to differential pinions. Casing is filled by working liquid for major part of its volume and by its journal bears on two bearings, compressed into semi-axial toothed wheels.

EFFECT: increasing of mechanism durability and providing of blocking of differential at growing of difference between number of revolutions of wheels.
