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 surface hardness of the existing brake line is poor, and it will be worn after long-term use, which will damage the internal brake line body

Embodiment Construction

[0031] see Figure 1-4 , the present invention relates to a bicycle wear-resistant brake device, comprising an outer cladding 1, two liner tubes 2 arranged side by side in parallel and a wire group 3, the lengths of the two liner tubes 2 are equal, and the liner tubes 2 are provided with There is a brake line 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 Bend along its length in a spiral shape (similar to a twisted steel wire rope), the metal wire group 3 has 15 to 25 metal wires, preferably 21 wires, and the outer cladding 1 is coated on the wire Group 3 outside.

[0032] The brake line body 4 includes an inner carbon fiber core wire group 4.1 and an outer layer resin layer 4.2. The carbon fiber core wire group 4.1 is composed of multiple bundles...

Abstract

The invention relates to an abrasion-resistant brake apparatus of a bicycle. The abrasion-resistant brake apparatus comprises an outer cladding (1), two lined pipes (2) and two metal wire groups (3); the lined pipes (2) are parallelly arranged side by side; each brake cable body (4) comprises a carbon fiber core wire group (4.1) and a resin layer (4.2) which are respectively arranged on the inner layer and outer layer of the brake cable body (4); a circular belt (5) is arranged at the end part of each brake cable body (4); the surface of the outer cladding (1) is coated with an abrasion-resistant coating material. The abrasion-resistant brake apparatus has the advantages that the brake cable body is uniform in stress, simple to form, light in quality, resistant to chemical corrosion, high in weatherability, resistant to abrasion and low in production cost; the friction force and support force between the lined pipes and the outer cladding are effectively increased, so that the relative sliding possibilities of the lined pipes and the outer cladding are low, and the using effect of a brake system is guaranteed; the circular belts arranged at the end parts of the brake cable bodies are used for fixing the brake cable bodies with handles, so that the brake cable bodies are prevented from coming away from the handles, and the riding safety is guaranteed.
