Description

Technical Field

[0001] The utility model relates to the technical field of air springs, in particular to an anti-dropout type air spring piston. Background Art

[0002] The rear air spring piston is used in air suspension. Some rear air spring pistons have an anti-slip effect. The rear air spring piston has the following functions: first, separating the air chambers: the piston divides the internal space of the cylinder into two or more independent air chambers. The gas pressure in each air chamber can be adjusted as needed to change the stiffness and stroke of the spring; second, transferring the load: when the external load acts on the air spring, the piston will move up and down along the inner wall of the cylinder, and the load will be converted into elastic deformation of the spring through the change of gas pressure, thereby playing a supporting and buffering role. However, the existing air spring piston is similar to a cover structure, with multiple fins arranged inside, and the fins and the piston body are integrated. When the fins are damaged, the air spring piston must be replaced as a whole, which is inconvenient to use. Utility Model Content
