Antioxidative brake cable with good braking effect

Abstract

The invention relates to an antioxidative brake cable with a good braking effect, which comprises an outer cladding layer (1), two inner lining pipes (2) which are arranged in parallel side by side, and two metal wire groups (3), wherein each brake cable body (4) comprises an inner layer carbon fiber core wire group (4.1) and an outer layer resin layer (4.2); one end of each outer sleeve pipe (5) is arranged on the outer cladding layer (1); the other end of each outer sleeve pipe extends outwards along the axial direction of the outer cladding layer (1) and is arranged on the corresponding brake cable body (1); and the surface of the outer cladding layer (1) is coated with an antioxidative coating. The antioxidative brake cable with the good braking effect has the advantages that the molding is simple; the mass is light; chemical corrosion resistance and weather resistance are good; the production cost is low; the stresses of the brake cable bodies are uniform; and since the surface of the outer cladding layer is coated with the antioxidative coating, the normal use 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. 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] Existing brake lines are exposed to the environment for a long time, which will cause their surface to be oxidized, which will make the braking of the brake line slow and lagging, and there will be safety hazards
