Description

Technical Field

[0001] The utility model relates to the technical field of air springs, and particularly relates to an air spring for a truck. Background Art

[0002] Air springs, commonly known as air bags, air bag cylinders, leather bag cylinders, etc. Air springs are widely used in self-adjusting air suspensions for commercial vehicles, buses, rail vehicles, machinery and equipment, and building bases. The air spring has a curved bladder structure, and the number of its curved bladders is usually 1-3, but it can also be designed and manufactured into a sleeve type, a membrane type, or a belt type air spring according to needs. Two bladder type air springs can also be superimposed and used under certain conditions.

[0003] In the patent application No.: CN202020800900.5, an air spring for a truck shock absorber is disclosed, which can achieve a good protection effect, make the air spring have good airtightness, avoid impurities in the air from entering, thereby reducing the internal wear of the air spring. At the same time, the protective sleeve plays a protective role for the air spring, avoiding collision and wear on the outer wall and extending the service life of the air spring. However, the above design still has deficiencies. The anti-slip property at both ends of the air spring is not good, the strength is insufficient, and there is also a lack of a protection mechanism at both ends of the air spring.

[0004] Therefore, we propose an air spring for a truck. Content of the Utility Model
