AUTOMOTIVE STEERING MECHANISM Russian patent published in 2018 - IPC B62D5/93 

FIELD: machine building.

SUBSTANCE: invention relates to automotive steering mechanism. Steering mechanism contains a hydraulic steering valve with supply lines, a priority valve with a control line and supply lines of controlled and uncontrolled flows, an executive hydraulic cylinder, power supply pump and an automatic driving device consisting of a three-position electrocontrolled proportional valve core and having a first row of supplies – pressure, drain, two cylinder and priority valve control. In each extreme position of the valve core, the active supply of the hydraulic cylinder is connected by a spool hydraulic supply with a pressure head and with a priority valve control input, and the other hydraulic cylinder connection is connected by a spool hydraulics with a drainage supply. Automatic driving device is further provided with a second row of the same-name supplies for connection to the supply lines of the hydrodrive, the pressure supply of the first row being connected to the supply line of the controlled priority valve flow. In a neutral position of the valve core all the same supplies of the first and second rows are connected by hydrolines to each other, and in extreme positions, the priority valve controlling the supply of the second row is prohibited.

EFFECT: reduced overall dimensions of the device by using only the flow of the hydrodrive to supply the device.
