Highly integrated eight-connected valve for electronic control air-suspension of vehicle

Abstract

The invention discloses a highly integrated eight-connected valve for an electronic control air-suspension of a vehicle. The eight-connected valve is connected with an air spring of an electronic control air-suspension system, and comprises a valve body, a valve cover connected with the valve body, eight electromagnetic coils and four pressure sensors, wherein the eight electromagnetic coils are uniformly arranged on the valve body through an electromagnetic oil seat, and are arranged in a two row type in an up-and-down symmetrical way; the four electromagnetic coils on the upper row are connected with the four electromagnetic coils on the lower part through a passage; an air inlet passage is arranged on the lower end in the valve body; air inlets are respectively formed in two sides of the air inlet passage; an air outlet passage is arranged in the upper end of the valve body; air outlets I are respectively formed in two sides of the air outlet passage; an air outlet II matched with the air outlet passage is formed in the top part of the valve body; an interface I and an interface II are respectively formed in the top part and the bottom part of the valve body. According to the highly integrated eight-connected valve for the electronic control air-suspension of the vehicle, the number of tee joints is reduced, the risk of system air leakage is reduced, and air inflation and exhaust of any air spring can be realized quickly and timely, so that the change of vehicle load is responded in time.

Description

[0001] Technical field [0002] The invention belongs to a pipeline system of a vehicle electronic control air suspension, and in particular relates to a highly integrated eight-way valve for a vehicle electronic control air suspension. [0003] Background technique [0004] The traditional electronically controlled air suspension piping system is generally composed of multiple joints, tees, pipelines and 5 independent 2-position 2-port solenoid valves. It has the following shortcomings: First, there are too many tees and joints, leading to the site The installation is complicated and messy, and it is particularly easy to cause the system to leak and unreliable; second, because the charging and exhausting share a pipeline and are controlled by a main solenoid valve, the system charging and exhausting cannot be realized at the same time, generally follow The principle of first charge and then discharge causes the air suspension system to fail to reflect the load changes and dynamic ...
