Air supply system of air suspension

Abstract

The invention discloses an air supply system of an air suspension, which comprises a compression pump assembly used for outputting high-pressure air; one end of the finned radiating pipe is communicated with the high-pressure gas output end of the compression pump assembly through a first pipeline, and the other end of the finned radiating pipe is communicated with the dryer through a second pipeline and is communicated with the pressure limiting valve through a third pipeline; one end of the pressure limiting valve is communicated with the second pipeline through a fifth pipeline, a pneumatic control valve is installed on the fifth pipeline, the second pipeline is sequentially communicated with an air valve, a first switching valve and a second switching valve through a sixth pipeline, and the air valve is communicated with the corresponding air spring; the second switching valve is communicated with the compression pump assembly through a seventh pipeline, and the pipelines are communicated with the air storage tank through an eighth pipeline. The air suspension system is simple in structure, the safety pressure can be adjusted, inflation and deflation of the air suspension air supply unit can be controlled according to the motion state of an automobile and the road condition, and the air suspension system adjusting function is achieved.

Description

technical field [0001] The invention relates to the field of automobile air suspension, in particular to an air supply system for air suspension. Background technique [0002] As an important part of the car's active suspension system, the air suspension is mainly composed of an air supply unit, an air spring, a shock absorption damping device, a lateral stabilizer, a height valve, a guiding force transmission mechanism, an air storage tank, and a pipeline. Real-time adjustment of the stiffness and damping of the suspension based on the motion state of the car and the road surface conditions, so that the suspension system is in the best shock absorption state, so that the vehicle has good comfort under various road conditions. With the development of people's requirements for vehicle ride comfort and suspension technology, air suspension is widely used in large passenger cars, heavy trucks, special vehicles and high-end small cars. [0003] As the core component of the air ...

AI Technical Summary

Problems solved by technology

The distribution valve assembly in the air supply system needs to be able to dynamically control the entry and exit of air, adjust the hardness and length of the air spring, control the inflation and deflation of the air supply unit of the air suspension, and realize the adjustment function of the air suspension system, while the existing air The number of control valves in the supply system is relatively large, the connection is cumbersome, and the safety pressure cannot be adjusted
