Problems solved by technology

[0002] The bicycle brake system includes accessories such as brake handles, brake lines, and brake calipers. The brake system of the prior art is usually provided with a front and a rear brake line and two corresponding brake handles and two brake calipers. The brake line is prone to breakage after being used for a period of time, causing brake failure and high potential safety hazards. In order to solve the above technical problems, it is necessary to use a two-line brake system with two front brake lines and two rear brake lines. The two brake lines of this brake system The length of the two front brake cables must be the same to ensure that the two brake cable bodies are evenly stressed during braking. However, the two independent brake cable bodies cannot guarantee the same length, and there are certain difficulties in assembly.
[0003] The existing brake line body is composed of an outer rubber hollow tube and an inner steel wire, its strength is not high enough, its chemical corrosion resistance is poor, its weather resistance is not good, and its production cost is relatively high
[0004] The friction and supporting force between the inner liner and the outer cladding of the existing brake line are not enough, and the inner liner and the outer sheath tend to slide relative to each other, which will cause the brake to not be tight and affect the use effect of the braking system
[0005] The end of the steel wire of the existing brake line is a hook used to fix the handle. After a long time of use, the hook will be deformed, which will cause the brake line to be disengaged from the handle, thereby causing brake failure and accidents

Embodiment Construction

[0029] see Figure 1-4 , the present invention relates to a wear-resistant brake line, comprising an outer cladding 1, two liner tubes 2 arranged side by side in parallel and a metal wire group 3, the lengths of the two liner tubes 2 are equal, and the liner tube 2 is provided with The brake line body 4, the metal wire group 3 includes a plurality of metal wires, the metal wires are closely arranged on the outer wall of the inner lining pipe 2, the length direction of the metal wires is consistent with the axial direction of the inner lining pipe 2, and the plurality of metal wires are arranged along the It is bent in a spiral shape in the length direction (similar to a twisted steel wire rope). The metal wire group 3 has 15 to 25 metal wires, preferably 21 wires. The outer cladding 1 is covered on the metal wire group 3 outside.

[0030] The brake line body 4 includes an inner carbon fiber core wire group 4.1 and an outer layer resin layer 4.2. The carbon fiber core wire gro...

Abstract

The invention relates to an abrasion-resistant brake cable. The abrasion-resistant brake cable comprises an outer covering layer (1), two lining pipes (2) and two metal wire sets (3), wherein the two lining pipes (2) are arranged side by side and in parallel. Each brake cable body (4) comprises a carbon fiber core wire set (4.1) on the inner layer and a resin layer (4.2) on the outer layer. An annular belt (5) is arranged at the end of each brake cable body (4). According to the abrasion-resistant brake cable, the effect that the two brake cable bodies (4) are as long as each other is guaranteed through the lining pipes, and thus the effect that the stress of the two brake cable bodies is uniform during braking is guaranteed; meanwhile, the brake cable bodies are easy to form, low in weight, resistant to chemical corrosion, good in weather resistance and low in production cost; the friction force and supporting force between the lining pipes and the outer covering layer of the brake cable are effectively increased, relative sliding between the lining pipes and the outer covering layer is unlikely to happen, and the using effect of a brake system is guaranteed; the annular belts at the ends of the brake cable bodies are used for fixing the brake cable bodies to a handle, so that the brake cable is prevented from being separated from the handle, and the traveling safety is guaranteed.
