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

Embodiment Construction

[0030] see Figure 1-4 , the present invention relates to a brake line, 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 a brake line is arranged inside the liner tube 2 The 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 length of the inner liner 2 The direction is bent in a spiral shape (similar to a twisted steel wire rope), and the metal wire group 3 has 15 to 25 metal wires, preferably 21 wires, and the outer cladding 1 is coated on the outside of the metal wire group 3 .

[0031] 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 w...

Abstract

The invention relates to a brake cable. The brake cable comprises an outer cladding (1), two lining tubes (2) arranged in parallel and two metal wire groups (3), wherein a brake cable body (4) comprises an inner carbon fiber core wire group (4.1) and an outer resin layer (4.2); and an annular belt (5) is arranged at the end part of the brake cable body (4). According to the brake cable, two brake cables are equal in length and uniformly stressed during braking by virtue of the lining tubes; the brake cable body has the advantages of simple molding, light mass, chemical corrosion resistance, good weather resistance and low production cost; the friction and supporting force between the lining tubes and the outer cladding can be effectively improved, and the lining tubes and the outer cladding cannot easily perform relative sliding, so that the using effect of a brake system is guaranteed; the annular belt arranged at the end part of the brake cable body is used for fixing the brake cable body and a handle, so that the brake cable cannot separate from the handle, and the traffic safety is guaranteed.
