Description

Bush intermediate pipe structure with reliability and economy

Technical Field

The utility model relates to the technical field of automobile accessories, in particular to a bushing middle pipe structure with reliability and economy.

Background

As one increases the operational stability requirements of automobiles, many suspension bushings have a fairly high radial stiffness. Many suspension bushings must therefore be added to the intermediate support tube structure to increase the radial stiffness of the product.

The conventional middle piece generally has two structures, as shown in fig. 1, the first is a whole cylindrical pipe, and a glue overflow groove with improved manufacturability is partially formed on the whole body of the pipe; the greatest disadvantage of the structure is that when the bushing is subjected to torsion acting force, the cylindrical middle pipe drives rubber on the bushing to move and deform excessively, so that the fatigue life of the product is greatly reduced, and the reliability of the pipe fitting of the structure is lower; referring to fig. 2, the second structure is a split structure using 2 semicircles; the fatigue life is relatively good, but the rigidity loss in the direction of the splicing parts of 2 sheet bodies is serious, so that the product is assembled in a fixed direction when being loaded; meanwhile, when the semicircular structure is used for vulcanizing a product, one product needs to be subjected to 2 middle sheets, so that the efficiency is low; and the framework is easy to be crushed when the mould is closed, so that the framework with the structure has poor economy.
