Abstract

The invention relates to an air suspension control system which comprises an ECU controller, a drive axle supporting airbag, a drive axle supporting airbag pressure sensor, a bearing axle supporting airbag, a bearing axle supporting airbag pressure sensor, a bearing axle lifting airbag pressure sensor, a bearing axle lifting airbag, three three-position three-way electromagnetic valves, an air storage cylinder, a height sensor and three switches, wherein the parts are electrically connected. The ECU controller achieves normal driving control, overall height adjustment control, lifting and landing control and/or load transfer control by controlling the three three-position three-way electromagnetic valves in a respective mode or in a combined mode. According to the technical scheme, the form of distributing an electromagnetic valve system is adopted, the main function of an electronic control system is achieved, the cost is lowered, and maintenance is convenient.

Description

technical field [0001] The invention belongs to the field of suspension, and specifically refers to an air suspension control system. Background technique [0002] The air suspension of heavy-duty trucks needs to have better vibration reduction and load-bearing performance. The air suspension with lift bridge control can lift or lower the load-carrying bridge according to the vehicle load, so that the whole vehicle has better fuel economy and load-carrying performance . The control system of the air suspension is the main component of the performance of the air suspension. The control system with the lifting bridge control is more complicated, and the electronic control of the ECU plus the integrated solenoid valve is mostly used. The damage of the integrated solenoid valve is not easy to be found. Maintenance Sometimes the whole assembly needs to be replaced, and the cost is high. [0003] At present, most of the control systems of air suspension with lifting axle at home...
