Abstract

The invention discloses a pipeline-variable air spring with an auxiliary air chamber. The pipeline-variable air spring with the auxiliary air chamber comprises a main air chamber and the auxiliary airchamber, the main air chamber and the auxiliary air chamber are connected, and the main air chamber and the auxiliary air chamber are connected through a plurality of branch pipes; each branch pipe is provided with an electromagnetic valve, and all the electromagnetic valves are connected with a controller; and the top of the main air chamber is provided with an upper cover plate for sealing themain air chamber. According to the pipeline-variable air spring with the auxiliary air chamber, the controllable range and controllable precision of the air spring can be improved, the driving smoothness of an automobile is improved, and characteristic requirements of different working conditions are met.

Description

technical field [0001] The invention belongs to the field of air springs, in particular to an air spring with a variable pipeline and an additional air chamber. Background technique [0002] With the development of technology in the fields of automobiles, rail transit, and industrial machinery, people have higher and higher requirements for the ride comfort of vehicles. The non-metallic elastic element composed of gas has been used more and more widely in various fields because of its unique vibration damping performance. "Building and Experimental Research on Air Spring Performance Test System with Additional Air Chambers" pointed out that the connecting pipeline between the main and auxiliary air chambers has a great influence on the performance of the spring system. Comprehensive aerodynamic theory, the gas flows through the connecting pipe When in the pipeline, its flow capacity is affected by factors such as the pressure difference at both ends of the pipeline, flow ve...
