The object of the present invention is achieved like this:

A kind of wear-resisting brake cable, is characterized in: described brake cable includes surrounding layer, the internal lining pipe of two side by side parallel settings and two tinsels, the length of two internal lining pipes is equal, brake cable body it is provided with in described internal lining pipe, two tinsels are respectively wound around the outer wall of internal lining pipe, surrounding layer is coated on outside two tinsels, described brake cable body includes the carbon fiber heart yearn group of internal layer and the wear-resistant coating of outer layer, its carbon fiber heart yearn group is made up of multi-beam carbon-fiber heart yearn, every a branch of carbon fiber core comprises 1000 ~ 200000 carbon fibers, the diameter of every carbon fiber is 5 ~ 15 microns, and the coating of described wear-resistant coating is by polyester modification acrylic resin, titanium dioxide, superfine alumina silicate, filler, firming agent, anti-skid wearable powder and solvent burden ratio form, and wherein the mass parts of each component is: polyester modification acrylic resin 40-55 part, titanium dioxide 6-12 part, superfine alumina silicate 5-8 part, filler 15-21 part, firming agent 10-15 part, anti-skid wearable powder 32-42 part, solvent 20-35 part, its groups of metal filaments has 15 ~ 25 one metal wires。

Compared with prior art, the invention has the beneficial effects as follows:

1. one brake cable of the present invention, its internal lining pipe ensures that two brake cable bodies are isometric, it is ensured that two brake cable body uniform force during brake。

2. one brake cable of the present invention, its brake cable body is made carbon fiber heart yearn group and is coated on the wear-resistant coating outside carbon fiber heart yearn group, and this body formed simple, light weight of prepared brake cable, resistance to chemical attack, good weatherability, production cost are low。

3. owing to the groups of metal filaments between surrounding layer and internal lining pipe is in radially closely arrangement, it is axially helical pattern, therefore effectively increase the frictional force between surrounding layer and internal lining pipe and support force, between surrounding layer and internal lining pipe, be not susceptible to relative sliding, it is ensured that brake system result of use。

Detailed description of the invention

Referring to Fig. 1, the present invention relates to a kind of wear-resisting brake cable, including surrounding layer 1, the internal lining pipe 2 of two side by side parallel settings and groups of metal filaments 3, the length of two internal lining pipes 2 is equal, it is provided with brake cable body 4 in described internal lining pipe 2, described groups of metal filaments 3 includes many one metal wires, tinsel is closely arranged at internal lining pipe 2 outer wall, length direction wiry is axial consistent with internal lining pipe 2, and the upper bending along its length of many one metal wires (is similar to the steel wire rope of twisting molding) twist, described groups of metal filaments 3 has 15 ~ 25 one metal wires, optimum is 21, described surrounding layer 1 is coated on outside groups of metal filaments 3。

Referring to Fig. 2-3, described brake cable body 4 includes the carbon fiber heart yearn group 4.1 of internal layer and the wear-resistant coating 4.2 of outer layer, described carbon fiber heart yearn group 4.1 is made up of multi-beam carbon-fiber heart yearn, every a branch of carbon fiber core comprises 1000 ~ 200000 carbon fibers, the diameter of every carbon fiber is 5 ~ 15 microns, the coating of wear-resistant coating is by polyester modification acrylic resin, titanium dioxide, superfine alumina silicate, filler, firming agent, anti-skid wearable powder and solvent burden ratio form, wherein the mass parts of each component is: polyester modification acrylic resin 40-55 part, titanium dioxide 6-12 part, superfine alumina silicate 5-8 part, filler 15-21 part, firming agent 10-15 part, anti-skid wearable powder 32-42 part, solvent 20-35 part。
