The invention discloses an air suspension electric control system with double height and pressure control, which comprises a controller, a height sensor, a pressure sensor, an air spring and an electromagnetic valve. When the vehicle is unloaded or lightly loaded, the left and right pressure sensors of the drive axle are used to control the attitude of the air suspension, which solves the problem that the air suspension electronic control system may not work normally when the vehicle is fully loaded or heavily loaded The left and right height sensors of the drive axle are used to control the attitude of the air suspension, which solves the problem of different heights of the left and right air suspensions and vehicle skew caused by the different loads on the left and right of the vehicle when the vehicle is heavy; the attitude of the air suspension is controlled by the height sensor or pressure sensor, Reduce manufacturing and assembly precision requirements, no need to adjust after assembly, saving a lot of manpower and material resources.
Description
technical field [0001] The invention belongs to the technical field of automobile chassis, in particular to the technical field of air suspension, in particular to an air suspension electric control system with double height and pressure control. Background technique [0002] The air suspension is mainly composed of elastic elements, damping elements, guiding elements and height control system. Its structure is as follows: figure 1 Shown: Air springs are elastic elements that primarily carry vertical loads. Shock absorbers are damping elements that mainly dampen vehicle vibrations. The thrust rod is the guiding mechanism of the air suspension, which bears and transmits longitudinal and lateral forces and moments. The height control system includes a controller, a solenoid valve, and a height sensor, which are mainly used to adjust the attitude of the air suspension. [0003] The working principle of the existing air suspension height control system: the controller control...
