Abstract

Official abstract text for this publication.

Disclosed are a shock absorber and an automobile. The shock absorber includes a shock absorber cylinder and an air spring arranged around the shock absorber cylinder. The air spring includes a damping spring and a piston. A free end of the damping spring is supported at a free end of the piston. A support is disposed between the piston and the shock absorber cylinder. The free end of the piston is supported on the shock absorber cylinder by the support. In the shock absorber according to the invention, the piston and the shock absorber cylinder can be connected in a simple way.

First claim

Opening claim text (preview).

What is claimed is: 1. A shock absorber, comprising a shock absorber cylinder and an air spring arranged around the shock absorber cylinder, wherein the air spring comprises a damping spring and a piston, a free end of the damping spring is supported at a free end of the piston, a support is disposed between the piston and the shock absorber cylinder, and the free end of the piston is supported on the shock absorber cylinder by the support, the support and the free end of the piston are integrally constructed, and an outer side of an upper end of the shock absorber cylinder is sleeved with an anti-impact cap, the support is arranged between the piston and the anti-impact cap. 2. The shock absorber according to claim 1 , wherein the periphery of the support abuts against the shock absorber cylinder. 3. The shock absorber according to claim 2 , wherein the support is provided with an opening. 4. The shock absorber according to claim 3 , wherein the opening is arranged on the periphery of the support. 5. The shock absorber according to claim 1 , wherein the shock absorber cylinder is sleeved with an anti-impact cap, and the support is arranged between the piston and the anti-impact cap. 6.
