High-strength brake cable

Abstract

The invention relates to a high-strength brake cable which comprises an outer wrapping layer (1), two parallel lining pipes (2) and two metal wire sets (3); each brake cable body (4) comprises an inner carbon fiber core wire set (4.1) and an outer resin layer (4.2); one end of an outer sleeve pipe (5) is arranged on the outer wrapping layer (1), and the other end of the outer sleeve pipe axially extends outwards along the outer wrapping layer (1) and is arranged on the brake cable body (4); an annular belt (6) is arranged at the end part of the brake cable body (4). According to the high-strength brake cable, two brake cable bodies are uniformly stressed and are easy to form, light in weight, resistant to chemical corrosion, good in weather resistance and low in production cost; the lining pipes and the outer wrapping layer of the brake cable are difficult to slide relatively, so that the use effect of a brake system is guaranteed; the outer sleeve pipe is capable of effectively protecting a connector part at the end part of the brake cable from being worn, thereby guaranteeing the driving safety.

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

[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
