High-strength high-strength wear-resistant brake line

Abstract

The present invention relates to a high-strength wear-resistant brake line which comprises an outer cladding layer (1), two lining tubes (2) side by side disposed in parallel and two metal wire groups (3), a brake line body (4) comprises an inner layer carbon fiber core line group (4.1) and an outer layer resin layer (4.2), one end of an outer sleeve tube (5) is arranged on the outer cladding layer (1), the other end of the outer sleeve tube (5) extends axially outwardly along the outer cladding layer (1), and is arranged on the brake line body (4), and the end portion of the brake line body (4) is provided with an endless belt (6). The two brake line bodies are uniformly forced when in a brake; the brake line body is simple in molding, light in weight, chemical-resistant, good in weather resistance and low in cost of production; the lining tubes and the cladding layer are less prone to relative sliding, and the used effect of the brake system can be ensured, the outer sleeve tube (5) can effectively protect an end connector part of the brake line from being worn, and driving safety is ensured.

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. 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 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 d...

[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 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
