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 surface of the existing brake line will be corroded after being used for a long time, which will affect the normal use of the brake line

Abstract

The invention relates to an anticorrosive bicycle brake apparatus. The apparatus comprises an outer cladding (1), two liner tubes (2) arranged in parallel and side by side, and two metal wire groups (3), each of brake cable bodies (4) comprises a carbon fiber core cable group (4.1) as an inner layer and a resin layer (4.2) as an outer layer, the end portion of each of the brake cable bodies (4) is provided with an annular belt (5), the surface of the outer cladding (1) is coated with an anticorrosive layer, and the anticorrosive layer comprises a bonding bottom layer and an anticorrosive surface layer. The anticorrosive bicycle brake apparatus has the advantages of simple molding, light weight, chemical corrosion resistance, good weatherability, low production cost and high safety; the force bearing of the two brake cable bodies is uniform in the brake process; sliding of liner tubes relative to the outer cladding is difficult, so the use effect of a brake system is guaranteed; and brake cables can effectively resist corrosion, so the service life is prolonged.
