Abstract

The invention relates to an air spring pressure control device and a control method thereof, in particular to an air spring pressure control device applied to a rail transit vehicle and a control method for the air spring pressure control device. The control device comprises a differential valve arranged between two adjacent air springs and used for balancing internal pressure of the air springs; the differential valve is communicated with the two air springs; and the control device also comprises height regulating valves respectively communicated with the air springs and used for respectively regulating the height of corresponding air springs. In addition, the invention also provides a control method for the control device with the structure. By the technical scheme, the invention provides an air spring pressure control device capable of automatically regulating the height of each air spring and balancing pressure between the air springs, and a control method employing the air spring pressure control device for balancing the pressure between the air springs.

Description

technical field [0001] The present invention relates to an air spring pressure control device and control method, more specifically, the present invention refers to an air spring pressure control device and control method applied to rail transit vehicles. Background technique [0002] The air spring is a kind of spring that is filled with compressed air in a retractable airtight container and utilizes the elastic action of air. Air springs are commonly known as airbags and capsules, and are usually curved capsules. The curved capsules are usually made of rubber, and the curved capsules are filled with compressed air. The air spring can carry a certain mass after being filled with compressed air, but when the mass changes, the height of the air spring will inevitably change, but under many conditions, the height change of the air spring needs to be effectively suppressed. [0003] In addition, when multiple air springs bear the same load at the same time, it is necessary to ...
