Problems solved by technology

After the two are assembled, due to the positional requirements, it is necessary to overcome the friction between the airbag and the buckle to rotate the buckle, which is time-consuming and labor-intensive, and the assembly process is time-consuming and labor-intensive.
In addition, since the airbag steel ring or the buckle will inevitably be deformed when the airbag is pried into the buckle, the risk of air spring leakage is increased.

Embodiment Construction

[0024] The present invention will be further described below in conjunction with accompanying drawing.

[0025] figure 1 A flowchart of the method of manufacturing the air spring 100 in this embodiment is shown. The method includes the following steps:

[0026] S10: inserting the first end of the straight cylindrical air-sac blastocyst into the clasp, so that the clasp abuts against the radially protruding convex ring on the second end of the air-sac blastocyst.

[0027] Such as figure 2 As shown, air spring 100 includes retaining ring 53 . The clasp 53 is a ring structure, preferably a ring. Buckle 53 generally adopts steel ring. The buckle 53 is provided with a plurality of through holes for bolts to pass through. The through hole is preferably a stepped hole. A plurality of through holes are uniformly distributed sequentially around the axis of the buckle ring 53 .

[0028] Such as image 3 As shown, the airbag blastocyst 50 is made of rubber that has not been vul...

Abstract

The invention relates to a method for manufacturing an air spring. The method comprises the following steps that S10, a first end of a straight cylinder-shaped airbag blank is inserted into a retaining ring, so that the retaining ring abuts against a convex ring protruding from a second end of the airbag blank in the radial direction; and S20, the airbag blank is vulcanized and shaped into an airbag. By adopting the method, the airbag and the retaining ring are assembled more conveniently and are not deformed, and thus the gas tightness of the air spring is better.

Description

technical field [0001] The invention relates to a method of manufacturing an air spring. Background technique [0002] The air spring system consists of four main components including airbag, buckle, upper cover and auxiliary spring. The main assembly steps are divided into four steps, which are auxiliary spring assembly, airbag and buckle assembly, airbag buckle and auxiliary spring assembly, and upper cover buckle assembly. The assembly process is cumbersome. [0003] In particular, the assembly between the buckle and the airbag is the most difficult. It is necessary to use special tooling to deform the steel ring of the airbag and then forcefully insert it into the buckle. After the two are assembled, due to the positional requirements, it is necessary to overcome the frictional force between the airbag and the buckle to rotate the buckle, which is time-consuming and labor-intensive, and the assembly process is time-consuming and laborious. In addition, since the airbag...
