AI Technical Summary
Technical Problem
The existing air springs have limited stiffness adjustment range, which cannot meet the needs of new energy vehicles for high smoothness and ride comfort.
Method used
An air spring assembly is designed, adopting a dual-chamber structure, the first chamber and the second chamber can be connected or disconnected, and only the first chamber serves as a working chamber when disconnected. By filling the adsorbent in the second chamber, its gas molecule adsorption capacity is enhanced, thereby expanding the stiffness adjustment range without changing the chamber volume.
Benefits of technology
A larger stiffness adjustment range is achieved, making the vehicle smoother when driving and improving the comfort of passengers.

Abstract
The invention relates to the technical field of automobile vibration reduction, in particular to an air spring assembly and a vehicle. A first cavity and a second cavity are formed in the air spring assembly, the first cavity and the second cavity can be communicated or disconnected, and only the first cavity serves as a working cavity when the first cavity and the second cavity are disconnected; the air spring assembly comprises a shock absorber, and the first cavity and the second cavity are arranged in the length direction of the shock absorber. The top seat assembly is arranged on the outer wall of the shock absorber in a sleeving mode, the top seat assembly comprises a first top seat and a second top seat which are buckled with each other, and the second cavity is formed in a space defined by the first top seat and the second top seat; the adsorption part is of a porous structure and is used for adsorbing high-pressure gas; the adsorption member is filled in the second chamber. The second cavity is filled with the adsorption part, so that the number of gas molecules capable of being adsorbed by the second cavity is increased under the condition that the volume of the second cavity is not changed, a larger rigidity adjusting range is provided, a vehicle is smoother during driving, and then the comfort of passengers is improved.
