Corrosion-resisting brake line good in stability

Abstract

The invention relates to a corrosion-resisting brake line good in stability. The corrosion-resisting brake line comprises an inner tube (1), a tubular layer (2), a first protection layer (3), a strengthening layer (4), a second protection layer (5) and a surface protection layer (6). The inner tube (1) is in a spring curve shape in the length direction, and a steel wire is arranged in the inner tube (1); and an annular belt (7) is arranged at the end of the steel wire, and the surface protection layer (6) comprises a binding bottom layer and a corrosion-resisting surface layer. By means of the corrosion-resisting brake line good in stability, the brake line outer layer is not prone to being scraped or damaged by the external force, so that the steel wire in the inner tube cannot pop out, and driving safety is ensured; the brake line can automatically retract back, so that folding of a vehicle is facilitated; the annular belt at the end of the steel wire is used for fixing the steel wire and a handle, so that the steel wire cannot be separated from the handle, and driving safety is ensured; and the brake line effectively resists corrosion, and the service life of the brake line is prolonged.

Description

technical field [0001] The invention relates to a brake cable for a folding bicycle brake system. The utility model belongs to the technical field of vehicle accessories. Background technique [0002] The folding car has the advantages of being foldable, easy to control, and easy to carry. During the folding process, no external tools are needed. The car can be folded or unfolded manually. After folding, it can be stored in the trunk of the car more conveniently. Or in the boarding box, the brake system of the vehicle includes brake handles, brake lines, brake calipers and other accessories. [0003] After the existing folding bicycle is folded, the brake line cannot be folded, and its length does not change, and a longer section is bent outside. It is easy to be hooked by external objects during the transportation of the vehicle, which affects the folding function of the vehicle; the existing vehicle brake The system only pays attention to the protection of longitudinal t...

AI Technical Summary

Problems solved by technology

[0003] After the existing folding bicycle is folded, the brake line cannot be folded, and its length does not change, and a longer section is bent outside. It is easy to be hooked by external objects during the transportation of the vehicle, which affects the folding function of the vehicle; the existing vehicle brake The system only pays attention to the protection of longitudinal tensile stress and compressive stress. The outer layer of the brake line is easily scratched or damaged by external force, which will cause the steel wire in the inner tube to pop out, and the brake system will fail, which will affect driving safety; The end of the steel wire is a hook used to fix the handle. After a long time of use, the hook will be deformed, which will cause the steel wire to be disengaged from the handle, resulting in brake failure and accidents.

[0004] The surface of the existing brake line will be corroded after being used for a long time, which will affect the normal use of the brake line
