STEERING CONTROL HYDRAULIC SYSTEM WITH TWO STEERING COMPONENTS AND VEHICLE WITH SAID SYSTEM

摘要

FIELD: transport.SUBSTANCE: invention relates to automotive industry. Steering hydraulic control system comprises first and second steering control components. First component is connected with first valve assembly including the first valve of steering control. Working fluid flow fed into steering control one or several cylinders is controlled by priority valve that sets priority between steering first and second components. Second valve assy comprises second steering control valve. Said priority valve is connected with second valve assy via hydraulic main line. Second valve can interact with flow proportioning valve. Method of control over steering system comprises two operating modes. In the first mode when the steering first component is not used second valve and/or flow proportioning valve are controlled by steering second component. In the second mode both second and first valve assemblies are used at a time when steering control first component is used. Vehicle comprises above said hydraulic control system for steering control. Control unit controls above described hydraulic system and incorporates machine-readable program executed to realise hydraulic system control jobs.EFFECT: ease of use, higher safety.25 cl, 4 dwg
