Since the installation space of the chassis part of the whole vehicle is very limited, the design of the axial installation space is very compact, which restricts the arrangement of a complete damping system on the air spring, so there is an urgent need for an air spring with a simple structure and a small installation space; in addition , the piston elastic part of the current air spring is easily affected by the spring matching parts, and cannot be optimized in the axial direction

Abstract
The invention discloses an air spring comprising an air spring cover and a piston. The piston is provided with a first piston component, an elastic damping component and a second piston component as well as a ripplepipe, wherein the elastic damping component is arranged between the first piston component and the second piston component; one end of the ripplepipe is connected with a piston; the other end of the ripplepipe is connected with the air spring cover; and a compression air work cavity is enclosed by the piston, the ripple pipe and the air spring cover. Axial optimization can be achieved for the piston component, so the overall vehicle can stably run.
Description
technical field [0001] The invention relates to an air spring, in particular to the field of automobile buffers. Background technique [0002] At present, air suspension is not a new technology developed in recent years. Air springs are installed between the body and the running mechanism of the car. It is fixed between the air spring cover and the piston of the operating mechanism, and mainly includes two parts: the air spring with compressed air inside and the shock absorber with variable damping. In actual use, this type of air spring often suffers from internal overload problems. Under the action of external force, the air spring bellows moves up and down with the coaxial piston. Compared with the traditional steel automobile suspension system, the air suspension has many advantages, the most important point is that the elastic coefficient of the spring, that is, the softness and hardness of the spring, can be automatically adjusted according to the needs. For example...
