WORKING MACHINE Russian patent published in 2013 - IPC B66F9/00 B60G17/16 

FIELD: transport.

SUBSTANCE: set of inventions relates to working machine and to method of its operation. Working machine comprises body, axle with wheels moving relative to body, speedometre and hydraulic control system. Hydraulic control system comprises control system actuator and control valve. Said actuator is mounted between body and shaft to control axle motion relative to body. Control valve constrains fluid flow in response to axle displacement relative to body. Control valve represents a solenoid valve controlled proportionally by controller. Said controller adjusts fluid flow constriction to allow larger fluid flow at machine speed increase. In compliance with first and second versions, proposed method consists in that hydraulic system comprises control valve constricting fluid flow in response to axle displacement relative to body. In compliance with second version, fluid flow constriction in operation of extra hydraulic service device is partially removed.

EFFECT: increased stability.
