Technical Field

[0002] In the existing positive suspension, the main spring is mainly supported by an external support frame arranged below it and an internal support frame structure arranged inside it. After searching, the application number "CN202321241386.6" discloses "an external support frame structure for the main spring of the positive suspension". It records that "a closed-loop sealing rib is raised on the first connecting surface of the external support frame, and an interference fit is formed between the mold and the sealing rib during vulcanization, so that the first connecting surface is ensured to build up pressure as a whole during vulcanization to prevent pressure release, which can effectively avoid the problem of glue running, avoid the trouble of subsequent trimming, simple structure, and effectively improve the production efficiency". By raising a closed-loop sealing rib on the first connecting surface of the external support frame, an interference fit is formed between the mold and the sealing rib during vulcanization, so that the first connecting surface is ensured to build up pressure as a whole during vulcanization to prevent pressure release, which can effectively avoid the problem of glue running, avoid the trouble of subsequent trimming, simple structure, and effectively improve the production efficiency.
