Abstract

The present invention relates to a high-strength high-temperature-resistant brake line which includes a brake line body (1) and a steel wire (2), the brake line body includes a liner tube (1.1) and an outer cladding layer (1.2), the liner tube (1.1) is arranged in the outer cladding layer (1.2), the outer cladding layer (1.2) is curved spring-form in the longitudinal direction, the metal wire group (2) is disposed in the liner tube (1.1), one end of an outer sleeve tube (3) is arranged outside the outer cladding layer (1.2), the other end of the outer sleeve tube (3) extends axially outwardly and is disposed on the steel wire (2), and the end portion of the metal wire group (2) is provided with an endless belt (4). The high-strength high-temperature-resistant brake line is capable of self-retracting, and facilitates folding of a vehicle, the metal wire group is high-strength and difficult to damage; and the endless belt is used for fixing the metal wire group with a handle, so that the brake line may not be separated from the handle, and driving safety can be ensured.

Description

The high temperature resistant brake cable that intensity is high

Technical field

The present invention relates to a kind of brake cable, for folding bicycle brake system。Belong to bicycle accessories technical field。

Background technology

Folded bicycle has manipulation collapsible, easy, portable advantage, also without by external tools in folding use procedure, manually folding or launch from being about to car, after folding, it is possible to be more conveniently accommodated in automobile trunk or boarding case。

Existing folding bicycle is after vehicle folding, and brake cable cannot be folded, and its length is not changed in, and longer one section of bending outside, is easily hooked to by external object in vehicle transport process, affects the folder function of vehicle；And the steel wire in existing brake cable internal lining pipe is owing to being single metal wire, so can cause its insufficient strength have impact on the result of use of brake system；Its end of the surrounding layer of existing brake cable is not owing to having trocar sheath, and therefore brake cable end-fitting part is easily worn and torn, and have impact on the result of use of brake system；The end of the steel wire in existing brake cable internal lining pipe is a hook for fixed handle, and after using the time longer, hook can deform, and so can cause that brake cable disengages with handle, thus brake failure, it is easy to have an accident。

Summary of the invention

It is an object of the invention to overcome above-mentioned deficiency, it is provided that the high temperature resistant brake cable that a kind of intensity is high, this brake cable brake cable body can automatic retracted, it is simple to vehicle folding；Groups of metal filaments includes many one metal wires, and tinsel is axially helical pattern, and groups of metal filaments intensity is high, is hardly damaged；And trocar sheath can effectively protect brake cable end-fitting part wears, and ensure that traffic safety。

The object of the present invention is achieved like this:

The high temperature resistant brake cable that a kind of intensity is high, it is characterized in: described brake cable includes brake cable body and steel wire, described brake cable body includes internal lining pipe and surrounding layer, internal lining pipe is arranged in surrounding layer, surrounding layer is longitudinally in spring curve shape, described groups of metal filaments is arranged in internal lining pipe, groups of metal filaments includes many one metal wires, length direction wiry is axial consistent with internal lining pipe, and the upper bending along its length of many one metal wires is twist, one end of described trocar sheath is arranged on outside surrounding layer, the other end extends axially outwardly and is arranged on steel wire, the end of described groups of metal filaments is provided with endless belt, high-temperaure coating is set outside surrounding layer, the coating of high-temperaure coating is made up of following proportioning: silicone acrylic emulsion 10-40 part, fluorosioloxane rubber 10-30 part, coalescents 2-8 part, dispersant 0.3-0.8 part, color stuffing 40-90 part, water 20-40 part and nano magnesia 3-5 part, described coalescents is made up of propylene glycol phenylate and alcohol ester 12, described dispersant is made up of sodium hexameta phosphate and polyacrylic acid sodium salt, described color stuffing is kieselguhr, described titanium dioxide is Rutile type titanium dioxide。

The high temperature resistant brake cable that a kind of intensity of the present invention is high, its groups of metal filaments has 15 ~ 25 one metal wires。

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

The high temperature resistant brake cable that a kind of intensity of the present invention is high, this brake cable brake cable body can automatic retracted, it is simple to vehicle folding；Groups of metal filaments includes many one metal wires, and tinsel is axially helical pattern, and groups of metal filaments intensity is high, is hardly damaged；And trocar sheath can effectively protect brake cable end-fitting part wears；Groups of metal filaments end is provided with an endless belt, fixes with handle, and therefore brake cable will not disengage with handle, it is ensured that traffic safety。
