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

Embodiment Construction

[0029] see Figure 1-4 , the present invention relates to a high-strength 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 tubes 2 are set inside There is a 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 liner 2, the length direction of the metal wires is consistent with the axial direction of the inner liner 2, and the plurality of metal wires Bend along its length in a spiral shape (similar to a twisted steel wire rope), the metal wire group 3 has 15 to 25 metal wires, preferably 21 wires, and the outer cladding 1 is coated on the 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 group 4.1 is composed of multiple bundles of carb...

Abstract

The invention relates to a high-strength brake cable which comprises an outer cladding layer (1), two side-by-side parallel lining tubes (2) and two metal wire groups (3), wherein each brake cable body (4) comprises a carbon fiber core wire group (4.1) on the inner layer and a resin layer (4.2) on the outer layer; one end of an outer sleeve (5) is arranged on the outer cladding layer (1); the other end of the outer sleeve (5) extends outwards along the outer cladding layer (1) axially and is arranged on a corresponding brake cable body (4). The high-strength brake cable has the advantages that due to the adoption of the lining tubes, the two brake cable bodies are equal in length, so as to be uniform in stress during braking; moreover, the brake cable bodies are simple to form, light in weight, high in chemical resistance and weather resistance, and low in production cost; according to the brake cable, the friction force and support force between the lining tubes and the outer cladding layer are effectively increased, so that the lining tubes and the outer cladding layer cannot slide easily relative to each other to ensure the using effect of a brake system; the outer sleeves can effectively prevent abrasion of end joint parts of the brake cable.
