Break-proof wear-resistant brake cable

Abstract

The invention relates to a break-proof wear-resistant brake cable comprising an inner tube (1), a tubular layer (2), a first protective layer (3), a reinforcing layer (4), a second protective layer (5) and a surface protective layer (6). A metal wire group is disposed within the inner tube (1) and includes a plurality of metal wires; the length direction of the metal wires is the same as the axial direction of the inner tube (1); the metal wires are spirally bent along the length direction; the surface protective layer (6) is a wear-resistant coating. The break-proof wear-resistant brake cable is wear resistant; the outer layer is less prone to scratch or damage by external force; the metal wires in the inner tube never pop out, and riding safety is guaranteed; the break-proof wear-resistant brake cable can automatically retract, thus folding of a vehicle is facilitated.

Description

technical field [0001] The invention relates to a brake line used in a bicycle brake system. The utility model belongs to the technical field of vehicle accessories. Background technique [0002] The brake system of the vehicle includes brake handles, brake lines, brake calipers and other accessories. [0003] And because the steel wire in the existing brake line inner tube is a single metal wire, it will cause its strength not enough, which affects the use effect of the brake system; the existing vehicle brake system only pays attention to the protection of longitudinal tensile stress and compressive stress. The outer layer of the cable is easily scratched or damaged by external forces, which will cause the steel wire in the inner tube to pop out, and the brake system will fail, which will affect driving safety. [0004] The surface hardness of the existing brake line is poor, and it will be worn after long-term use, thereby damaging the inner body of the brake line. Co...
