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 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 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 line is exposed to the environment for a long time, which will cause the outer cladding to be oxidized, thus making the braking of the brake line slow and lagging, and there will be safety hazards

Embodiment Construction

[0032] see Figure 1-4 , the present invention relates to a bicycle brake device, comprising an outer cladding 1, two liner tubes 2 arranged side by side in parallel and a metal wire group 3, the lengths of the two liner tubes 2 are equal, and the inner liner tube 2 is provided with a brake The wire body 4, the metal wire group 3 includes a plurality of metal wires, the metal wires are closely arranged on the outer wall of the inner liner 2, the length direction of the metal wires is consistent with the axial direction of the inner liner 2, and the plurality of metal wires are arranged along the outer wall of the inner liner 2. It is bent in a spiral shape in the length direction (similar to a twisted steel wire rope). The metal wire group 3 has 15 to 25 metal wires, preferably 21 wires. The outer cladding 1 is covered on the metal wire group 3 outside.

[0033] The brake line body 4 includes an inner carbon fiber core wire group 4.1 and an outer layer resin layer 4.2. The ca...

Abstract

The invention relates to a brake device of a bicycle. The brake device of the bicycle comprises an outer cladding layer (1), two lining pipes (2) which are arranged side by side in parallel and two metal wire groups (3). Each brake cable body (4) comprises a carbon fiber core wire group (4.1) at the inner layer and a resin layer (4.2) at the outer layer. An endless belt (5) is arranged at the end portion of each brake cable body (4). An oxidation resistant coating is coated on the surface of the outer cladding layer (1). According to the brake device of the bicycle, the two brake cable bodies are guaranteed to be in same length through the lining pipes, and the two brake cable bodies are guaranteed to be balance in stress; at the same time, the brake cable bodies are simple in molding, light in mass, resistant to chemical attack, good in weather fastness, low in production cost, good in brake effect and high in the security of the brake cables; the oxidation resistant coating is coated on the surface of the outer cladding layer, and the normal use of the brake cables is guaranteed.
