High-strength acid-resistant brake cable

Abstract

The invention relates to a high-strength acid-resistant brake cable. The high-strength acid-resistant brake cable comprises an outer covering layer (1), two inner lining tubes (2) parallelly arranged side by side and two metal wire sets. Each brake cable body (4) comprises an inner-layer carbon fiber core wire set (4.1) and an outer-layer resin layer (4.2). One end of an outer sleeve (5) is arranged on the outer covering layer (1), and the other end of the outer sleeve (5) extends outwards in the axial direction and is arranged on the brake cable bodies (4). The ends of the brake cable bodies (4) are provided with an annular belt (6). The surface of the outer covering layer (1) is provided with an acid-resistant coating. The high-strength acid-resistant brake cable is easy to form, light in mass, resistant to chemical corrosion, good in weather resistance and low in production cost, traffic safety is achieved, and stress borne by the brake cable bodies is uniform; the surface of the outer covering layer is provided with the acid-resistant coating, so that the brake cable bodies are protected effectively, and normal using of the brake cable 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

[0006] The outer coating of the existing brake line has been exposed to the environment for a long time. Due to the high content of sulfur dioxide in the air and the acidity of the rain, the surface of the brake line is prone to aging and falling off, which will affect the normal use of the brake line. In severe cases, there will be Security risks
