HYDRAULIC STEERING SYSTEMS FOR VEHICLE WHEELS Russian patent published in 2022 - IPC B62D7/02 B62D7/15 

FIELD: vehicles.

SUBSTANCE: group of inventions relates to steering system 10 for vehicle wheel 12, a vehicle steering system and a vehicle. Wheel steering system comprises wheel bracket 14 for installation of controlled wheel 12, wherein wheel bracket 14 is installed with possibility of rotation relative to vehicle around axis of rotation, which makes it possible to control wheel 12. Hydraulic cylinder 20 comprises a piston and an assembly of a rigid connecting rod 22 extending from the piston of cylinder 20. Rigid connecting rod assembly 22 comprises first section 22 configured to reciprocate in and out of cylinder 20, and second section 26, which rigidly passes from first section 22 to connection 50 of pivot point, where it is connected with possibility of rotation with wheel bracket 14 with displacement relative to pivot axis. Hydraulic cylinder 20 is rotatably mounted on the vehicle so that it cannot translate relative to the vehicle, but can change its position relative to vehicle. Due to the rigid connecting rod assembly 22 and the hinged connection with wheel bracket 14, as well as cylinder 20, installed with possibility of rotation on vehicle, transverse deformations on seals of hydraulic cylinder 20 are prevented. 12. Steering system comprises: a first steering system for a first wheel and a second steering system for a second vehicle wheel and a hydraulic circuit, connecting hydraulic cylinders of the first and second steering systems in series.

EFFECT: higher reliability, lower costs of manufacturing and replacement.
