Problems solved by technology

[0003] (1) Existing solenoid valve groups generally use a plurality of conventional solenoid valves with valve blocks to connect the hydraulic oil circuit. The volume of the valve block is large, and the processing of the internal flow channel of the valve block is complicated, resulting in excessive overall cost. high
[0004] (2) When the existing solenoid valve group switches the steering mode, it needs to energize the electromagnet for a long time. The electromagnet is energized for a long time and generates heat, especially in summer, the coil heating temperature is very high, which seriously affects the electromagnet. service life, affecting the reliability of steering mode switching control
[0005] (3) The design redundancy of the existing solenoid valve group is low. When an electrical failure occurs, the steering system will be seriously affected, affecting the safety of the steering

Abstract

The present invention proposes a hydraulic steering mode control valve, including: a valve body, an end cover, a connecting block, a valve core, a positioning valve core, a positioning solenoid valve, a first electromagnet, a second electromagnet, a first spring, and a second spring . The hydraulic steering mode control valve according to the embodiment of the present invention has a simple and reasonable structure and low manufacturing cost, and can realize reliable and safe control of the hydraulic steering mode.

Description

technical field [0001] The invention relates to a hydraulic valve, in particular to a hydraulic steering mode control valve. Background technique [0002] Because hydraulic power steering has the advantages of compact structure, light weight, small size, high sensitivity, good stability, ability to absorb road impact and no need for additional lubrication devices, it is widely used in engineering vehicles. In order to adapt to various operating conditions, the steering system of engineering vehicles needs to switch between three steering modes: two-wheel steering, four-wheel steering and crab steering. Currently, combined solenoid valves are generally used to control steering mode switching. Although the existing solenoid valve group can realize the switching of the steering mode, it has the following disadvantages: [0003] (1) Existing solenoid valve groups generally use a plurality of conventional solenoid valves with valve blocks to connect the hydraulic oil circuit. Th...
