[0003] However, the existing air spring system top rubber assembly has some deficiencies in practical application. The elastic structure of the traditional top rubber assembly is relatively single, and it is difficult to adaptively adjust according to the complex deformation of the air spring during vehicle driving. For example, when the vehicle is rapidly accelerated, braked or turned, the air spring will be compressed, stretched and twisted to varying degrees, and the traditional top rubber assembly cannot timely and effectively follow these deformations, resulting in stress concentration in the local area, accelerating the wear of the top rubber assembly and the air spring, reducing the service life of the components, and also affecting the shock absorption effect of the air spring system, making the ride comfort of the vehicle decline. In high temperature, high humidity or harsh road conditions, the existing top rubber assembly may have problems such as reduced sealing performance, accelerated aging of rubber materials, and further affecting the stability and reliability of the entire air spring system. Therefore, a self-adaptive deformation air spring system top rubber assembly is needed. SUMMARY

[0006] Preferably, the top surface of the upper cover plate is provided with a reinforcing rib for enhancing the compression resistance.

[0007] Preferably, the reinforcing rib is radially distributed around the outside of the installation boss on the top of the upper cover plate.

[0008] Preferably, the elastic buffer body comprises a rubber column and a hollow structure, the rubber column is internally provided with a hollow structure, and the hollow structure is distributed in a honeycomb shape inside the rubber column.

[0009] Preferably, the elastic buffer body is provided with eight groups, and the eight groups of the elastic buffer body are arranged in a circular manner with respect to the center of the lower base.

[0010] Preferably, the telescopic elastic rod comprises a telescopic column, a lower connecting block and a micro spring, the outer wall of the telescopic column is attached to the lower connecting block, and the bottom of the telescopic column is connected with the micro spring inside the lower connecting block.

[0011] Preferably, the lower connecting block is provided with a sliding groove matched with the telescopic column.

[0012] Preferably, the outer walls of the upper cover plate and the lower base are provided with a sealing protective layer for sealing protection.

[0013] Compared with the prior art, the utility model has the advantages that:

[0014] When the air spring deforms to different degrees according to the road conditions and the driving state of the vehicle, the elastic buffer body first absorbs part of the energy through the elastic deformation of the elastic buffer body, plays a preliminary buffering role, and the telescopic elastic rod is retracted, so that the distance between the upper cover plate and the lower base is reduced, so that the whole top rubber assembly adapts to the compression deformation of the air spring, and the normal work of the top rubber assembly and the air spring is ensured. In the whole process, the sealing protective layer always protects the components inside the top rubber assembly, prevents the invasion of external impurities, and ensures that the top rubber assembly can work stably and reliably under various complex working conditions.
