Description

Technical Field

[0001] The utility model relates to the technical field of vehicle air springs, in particular to an air spring buckling structure. Background Art

[0002] At present, the bladder of automotive air springs is generally buckled on the guide tube, and the bladder needs to be assembled with the support ring first. The positioning of the traditional guide tube during buckling mainly relies on the end face of the bladder and the guide tube itself, resulting in reduced positioning accuracy. Because the bladder is a rubber part, it is easy to deform, so the positioning accuracy is poor. During actual buckling, the manufacturing efficiency and quality will also be reduced due to its positioning problem. Utility Model Content

[0003] In order to solve the technical problems existing in the background technology, the utility model proposes an air spring buckling structure.

[0004] The utility model proposes an air spring buckling structure, including a bladder installed with a support ring and a guide cylinder with a positioning step, the bladder is located in the guide cylinder, the lower end of the guide cylinder is connected to a positioning tool, and the buckling structure also includes a buckling piece for buckling the bladder at the buckling position of the guide cylinder.

[0005] Preferably, the buckling piece is configured as a single-edged buckling knife.

[0006] Preferably, the lower end of the guide cylinder is placed on the upper end of the positioning tooling.

[0007] Preferably, the positioning step of the guide cylinder is arranged close to the buckling position of the guide cylinder.

[0008] Preferably, the support ring is configured as a vulcanized support ring.

[0009] In the utility model, the air spring buckling structure proposed has a guide tube with a positioning step to position the bladder support ring. When buckling, only the positioning of the guide tube needs to be considered. The bladder of the vulcanized support ring is accurately positioned. The use of a single-edged buckling knife can avoid the problem of over-positioning, reduce manufacturing costs, facilitate positioning during buckling, greatly improve buckling efficiency, and improve product quality at the same time.

[0010] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
