Problems solved by technology

When the air spring or air line is abnormal, it may cause the height of one side of the car to be different from the other side, which cannot be actively adjusted by the height control valve
In addition, this structure will also generate a large roll angle when the vehicle turns, which will affect the safety and stability of the vehicle.

Abstract

The invention discloses a self-adjusting air suspension system which comprises air springs, a height control valve, an air pump and a control system, wherein the exhaust port of the air pump is communicated with the air springs through the height control valve; both sides of each axle are respectively provided with at least one air spring, and the air springs on both sides of each axle are communicated with each other by a balance pipeline; and the command output end of the control system is connected with the command receiving end of the height control valve. The balance pipelines between the air springs on the two sides can automatically balance the pressure in the air springs on the two sides, so that the air springs on the two sides are kept on the same height, thereby keeping the vehicle body balanced and enhancing the comfort of the vehicle. The structure of the invention simplifies the valve configuration and has the advantages of simpler structure and lower cost as compared with the prior art.

Description

technical field [0001] The present invention relates to an air suspension system, in particular to a self-adjusting air suspension system for vehicles. Background technique [0002] The suspension system of the vehicle is used to reduce the impact of ground undulations on the vehicle, thereby improving the driving safety and comfort of the vehicle. In semi-trailer or traction locomotives or large passenger cars, air suspension systems are being used more and more. The air suspension system adjusts the entry and exit of compressed air in the air spring according to the load, thereby controlling the height of the vehicle to provide stability when the vehicle is running. Normally, the air suspension system monitors the change of the height of the frame, and adjusts the air pressure in the air spring between the frame and the axle through the height control valve to keep the suspension stably at the set height. [0003] The air suspension system in the prior art has the abilit...
