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 two brake lines, one front and one rear, and two corresponding brake handles and two brake calipers. Brake wires tend to break 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-wire brake system with two front brake wires and two rear brake wires. The two brake wires of this brake system The length of the two front brake cables needs to be the same to ensure that the two brake cable bodies are evenly stressed during braking, but 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 existing brake line liner and the outer cladding are not enough, and the inner liner and the outer cladding 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; the existing The end of the outer cladding layer of the brake line has no outer sleeve, so the end joint of the brake line is easy to wear, which affects the use effect of the brake system
[0005] The end of the existing brake line body 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
[0006] The surface hardness of the existing brake line is poor, and it will be worn after long-term use, which will damage the internal brake line body

Embodiment Construction

[0034] see Figure 1-4 , the present invention relates to a high-strength 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 A brake line body 4 is arranged inside, and the metal wire group 3 includes a plurality of metal wires, the metal wires are closely arranged on the outer wall of the inner liner 2, the length direction of the metal wires is consistent with the axial direction of the inner liner 2, and a plurality of The metal wire is bent in a spiral shape along its length (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 coated on Wire group 3 outside.

[0035] 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 group 4.1 is composed of multiple bundle...

Abstract

The invention relates to a high-strength wear-resistant brake cable. The brake cable comprises an outer covering layer (1), two lining pipes (2) which are arranged in parallel side by side, and two metal wire groups (3); each brake cable body (4) comprises a carbon fiber core wire group (4.1) in an inner layer and a resin layer (4.2) in an outer layer; one end of each outer casing pipe (5) is arranged on the outer covering layer (1), and the other end of each outer casing pipe (5) extends outwards along the axial direction of the outer covering layer (1) and is arranged on the corresponding brake cable body (4); the end part of each brake cable body (4) is provided with an annular belt (6), and the surface of the outer covering layer (1) is coated with a wear-resistant coating layer. The high-strength wear-resistant brake cable has the advantages of simple forming, light weight, chemical corrosion resistance, good weather resistance, wear resistance, low cost of production, uniform stress of the brake cable bodies, and safe driving.
