High-strength abrasion-resistant brake cable

Abstract

The invention relates to a high-strength abrasion-resistant brake cable. The abrasion-resistant brake cable comprises an outer cladding layer (1), two inner lining pipes (2) arranged in parallel side by side, and two metal wire sets (3), wherein a brake cable body (4) comprises an inner carbon fiber core wire set layer (4.1) and an outer resin layer (4.2), one end of an outer sleeve (5) is arranged on the outer cladding layer (1), and the other end of the outer sleeve is outwards extended in the axial direction of the outer cladding layer (1) and is arranged on the brake cable body (4). According to the high-strength abrasion-resistant brake cable, the lining pipes can ensure the equal length of the two brake cables, so as to ensure that the two brake cable bodies are stressed uniformly when in braking; meanwhile, the brake cable body can be molded simply, has light weight, and has chemical corrosion resistance and good weather resistance and is low in production cost; the friction force and the supporting force between the lining pipe and the outer cladding layer can be effectively increased, the lining pipe and the outer cladding layer cannot easily slip relatively, the using effect of the braking system is ensured, and the outer sleeve can effectively prevent the end joint of the brake cable from being abraded partially.

Description

technical field [0001] The invention relates to a brake line used in a bicycle brake system. It belongs to the field of bicycle accessories. Background technique [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. 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. However, the two independent brake cable bodies cannot guarantee the same length, and there are certain difficultie...

[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
