STEERING ARRANGEMENT Russian patent published in 2018 - IPC B62D5/30 B62D5/00 A01B69/00 

FIELD: machine building.

SUBSTANCE: group of inventions relates to embodiments of a steering arrangement. Device comprises a first hydraulic pressure chamber, a second hydraulic pressure chamber, a third hydraulic pressure chamber and a fourth hydraulic pressure chamber, a pumping system for supplying pressurized fluid to the steering system, a steering system for supplying fluid under pressure to one or more pressure chambers from the group, including the first, second, third and fourth hydraulic pressure chambers. Steering system has a first mode, wherein the pressurized liquid is simultaneously supplied to the first and third hydraulic pressure chambers to provide guidance in the first direction, or the liquid under pressure is simultaneously fed to the second and the fourth hydraulic pressure chamber to provide guidance in the second direction. Steering system has a second mode, in which the fluid under pressure is supplied by an automatic steering system to the first or third hydraulic pressure chamber to provide guidance in the first direction, or pressurized fluid is supplied by the automatic steering system to the second or to the fourth hydraulic pressure chamber for providing the second direction, and the steering ratio in the second mode is higher than in the first mode.

EFFECT: automatic control with different modes of operation is provided.
