[0002] Automotive parts are the various units that make up the whole of automotive parts processing and the products that serve automotive parts processing. In order to reduce costs and capture the market, many multinational automotive parts companies have gone international. Coil spring non-independent suspension is a type of composite suspension. In cars equipped with this type of rear suspension, the structure of the rear axle has a significant impact on the stiffness characteristics of the rear suspension. Because the coil spring, as an elastic element, can only bear vertical loads, its suspension system must be equipped with a guiding mechanism and a shock absorber. Coil spring non-independent suspension is a type of composite suspension. In cars equipped with this type of rear suspension, the structure of the rear axle has a significant impact on the stiffness characteristics of the rear suspension.

[0003] Currently, many air shock absorbers on the market are bag-type shock absorbers. Because the walls of bag shock absorbers are relatively thin, they can withstand less pressure. When there is even a little pressure, they will expand and deform without the capsule, resulting in poor shock absorption. Since the coil spring is made of metal and the bag capsule is made of rubber, and the capsule wall is relatively thin, it will break quickly due to the continuous friction between the capsule wall and the inner wall of the coil spring, resulting in a short service life.
