The system comprises an electric air pump device, internal pipelines, an ECU, a pressure sensor and an electromagnetic valve group which are integrated; the electric air pump device is driven by a motor; the electric air pump device is connected with an air storage tank through an internal pipeline I; the electric air pump device is connected with the electromagnetic valve group through an internal pipeline II; the electromagnetic valve group is connected with an air spring through an internal pipeline III; the electric air pump device is connected with external atmosphere through an internal pipeline IV; the electric air pump device and the electromagnetic valve group are both connected with the ECU; the ECU is provided with a connector; the electromagnetic valve group is provided with an electromagnetic valve group valve port, an air path interface and an air filter interface; and the air filter interface is connected with an air filter. By adopting integrated closed-loop control, energy consumption can be reduced, higher system availability and better performance are ensured, cyclic use under various conditions is ensured, moisture impurities are prevented from influencing system work, and the system is compact in structure, small in size and weight, light in weight, energy-saving and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of vehicle control, in particular to an integrated air suspension air supply system. Background technique [0002] At present, the air supply system of vehicle air suspension generally adopts open-loop control. Open-loop control means that the gas for lifting the body is directly obtained from the outside atmosphere. Inflation; when the body needs to be lowered, the gas in the air spring is directly discharged into the atmosphere through the exhaust valve to achieve the effect of lowering the body. Open-loop control frequently interacts with the atmosphere during the working process, so the moisture in the atmosphere will inevitably enter the solenoid valve group of the system, which will adversely affect the work of the solenoid valve group. However, the traditional open-loop system will cause the compressor to overheat after two or three cycles. On the one hand, air must be sucked in from the outside, and...

Problems solved by technology

However, in the existing technology, the air suspension air supply system does not have integrated integration, and generally consists of multiple scattered components. The ECU automatically adjusts the system's inflation and exhaust according to the signal of the sensor, and never performs system integration. Integration, its structure is very complicated, the volume and weight are large, it takes up a lot of space, and consumes a lot of energy, which does not meet the current national theme of energy conservation and environmental protection, so it is necessary to improve
