AI Technical Summary

Technical Problem

Traditional air spring guide sleeves are designed with a fixed length, which cannot adapt to the needs of air springs at different heights, resulting in high development costs and long development cycles. Furthermore, they cannot be used after deformation, leading to serious waste of resources.

Method used

It adopts a multi-segment variable length bladder guide sleeve, which uses a segmented structure and detachable connection method. The second segment is a variable length segment. If the first segment fails, it can be disassembled and replaced. The third segment can continue to be used. The threaded connection ensures stability and flexibility.

Benefits of technology

It enables flexible adjustment of the total length of the air spring guide sleeve, adapting to the needs of air springs at different heights, reducing development costs, shortening the development cycle, and reducing resource waste.

Abstract

The utility model provides a multi-section variable-length leather bag guide sleeve, which comprises a first section, a second section and a third section which are sequentially connected, the first section is connected with a leather bag of an air spring in a buckling manner, the second section is detachably connected between the first section and the third section, and the third section is connected onto a structural member of the air spring. The first section is a buckling section of the leather bag guide sleeve, the second section is a variable-length section of the leather bag guide sleeve, and the third section is a tail section of the leather bag guide sleeve. By adopting a segmented structure and a detachable connection mode, the second section of the leather bag guide sleeve is the variable-length section and is adaptive to air springs with different heights, and the first section, namely the buckling section, is detached and replaced after being invalid in use, so that the second section, namely the variable-length section, and the third section, namely the tail section, can be continuously used; the rubber bag guide sleeve can meet the requirements of air springs with different heights, meanwhile, the development cost is reduced, and the development period is shortened.
