Anti-deflection valve for vehicle steering

Abstract

The invention discloses an anti-deflection valve for vehicle steering. The anti-deflection valve is in a left-and-right symmetric structure and is characterized by comprising a valve body (1), pressure regulating valve components (21) and safety valve components (2). Two oil inlets (A1) and (A2) are symmetrically arranged downwards on two sides of the outer wall of the valve body close to the middle, and two oil outlets (B1) and (B2) are symmetrically arranged on the rear wall of the valve body (1). Two sets of regulating valve components (21) are symmetrically arranged inside the valve body (1), a control valve core (15) is mounted in the middle, the outer diameter of the control valve core (15) is in clearance fit with the inner diameter of the valve body (1), and the two sets of safety valve components (2) are symmetrically arranged on the upper portion of the valve body (1). The oil inlets (A1) and (A2) are respectively communicated with two oil chambers formed by the pressure regulating valve components (21) in the valve body (1) and the control valve core (15). The anti-deflection valve for vehicle steering is simple in structure and high in applicability, integrates functions of twin channel hydraulic-control pressure regulating valves and twin channel safety valves, and can meet specific working conditions of steering of vehicles of various models and various loads.

Description

technical field [0001] The invention belongs to the technical field of hydraulic transmission and servo, and in particular relates to a vehicle steering anti-sway valve. Background technique [0002] When a multi-axle heavy-duty vehicle running at high speed is turning or going straight, due to the large inertia of the rear axle and the low steering load, the tail of the vehicle is prone to sway. This is a common problem faced by multi-axle large vehicles at home and abroad when driving at high speed technical challenge. In order to solve this inherent problem, an anti-sway valve can be added in the steering hydraulic circuit of the rear axle of the vehicle to coordinate the action sequence of the front and rear axles when the vehicle is running, and prevent the sway phenomenon caused by the rear axle of the vehicle moving ahead of the front axle. At the same time, the integrated design of the dual-way safety valve can also provide overpressure protection for the steering h...
