Description

Technical Field

[0001] The utility model relates to the technical field of air spring production, in particular to an air spring alignment assembly tool. Background Art

[0002] The air suspension system includes air springs, shock absorbers, air supply units (such as air compressors, one-way valves, air circuits, air tanks, etc.), guide mechanisms and vehicle height control systems. Air springs can be divided into three types according to the structural type of the airbag: bag type, membrane type and composite type. Among them, the bag type air spring consists of a rubber airbag with cords and compressed air enclosed in it. The inner layer of the airbag is made of airtight rubber, while the outer layer is made of oil-resistant rubber. The airbag is generally made into two sections, but there are also single sections or three or four sections. The more sections there are, the better the elasticity, but the sealing is poor. There are steel waist rings between the sections to prevent the middle part from radial expansion and prevent friction between the two sections. The upper and lower covers of the airbag seal the airbag, so it is necessary to design a set of tooling that can be assembled in place to ensure that the air spring parts are assembled in place.
