Problems solved by technology

[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 inner liner and the outer cladding of the existing brake line are not enough, and the inner liner and the outer sheath 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
[0005] The end of the steel wire of the existing brake line 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 cladding of the existing brake lines has been exposed to the environment for a long time. Under the high temperature in summer, the outer cladding is easy to crack, which will affect the normal use of the brake lines. In severe cases, there will be safety hazards

Abstract

The invention relates to a high-temperature-resistant braking device for a bicycle. The high-temperature-resistant braking device comprises an outer coating layer (1), two inner liner pipes (2) which are in parallel arranged side by side and two metal wire sets (3), wherein each brake cable body (4) comprises a carbon fiber core set (4.1) in an inner layer and a resin layer (4.2) in an outer layer; an endless loop built belt (5) is arranged at the end parts of the brake cable bodies (4); a high-temperature-resistant coating is arranged on the surface of the outer coating layer (1). According to the high-temperature-resistant braking device for the bicycle, disclosed by the invention, the inner liner pipes are arranged, so that the situation that the two brake cables are in the same length is guaranteed, and the situation that the two brake cable bodies are uniformly stressed when the bicycle is braked is guaranteed; besides, the brake cable body is simple to form, light in weight, high in chemical resistance, high in weather resistance, low in production cost and high in the safety of the brake cable; the high-temperature-resistant coating is arranged on the surface of the outer coating layer, so that the brake cable is effectively protected, and the normal use of the brake cable is guaranteed.
