METHOD OF REMOTE HYDRAULIC CONTROL AND SELF-PROPELLED VEHICLE REMOTE HYDRAULIC CONTROL Russian patent published in 2013 - IPC B62D5/06 B62D15/00 

FIELD: transport.

SUBSTANCE: invention relates to automotive industry. proposed device comprises steering wheel and mechanism to convert steering wheel turn angle into appropriate oil flow to guide wheels turn hydraulic cylinder. Said converter comprises oil pressure hydraulic control valves controlled via step-down gearing and arranged in remote control oil lines. Said oil lines communicate oil pump with hydraulic cylinder. The latter can convert oil pressure in rod displacement and is articulated with centering threshold spring arranged between fixed stops. Hydraulic cylinder is articulated with guide wheels turn hydraulic cylinder hydraulic control valve. Hydraulic control valve control channels are communicated with guide wheels turn hydraulic cylinder engaged with hydraulic control valve via feedback. Method of vehicle turn control whereby vehicle turn signal is generated by revolving steering wheel. Said signal is converted in oil flow from pump corresponding to sheering wheel turn angle to direct oil flow in control pipes to hydraulic cylinder. Hydraulic cylinder turns vehicle turn actuate in compliance with steering wheel turn. Turn signal is converted in oil flow pressure in oil control lines corresponding to steering wheel turn from position corresponding to vehicle straight motion. Oil flow pressure contracts threshold spring after reaching design magnitude at steering wheel free run to displace hydraulic control slide valve in compliance with threshold spring contraction.

EFFECT: higher accuracy of control.
