Abstract
The invention relates to a brake cable which comprises an outer wrapping layer (1), two parallel lining pipes (2) and two wound springs (3); each brake cable body (4) comprises an inner carbon fiber core wire set (4.1) and an outer resin layer (4.2); an annular belt (5) is arranged at the end part of the brake cable body (4). According to the high-strength brake cable, two brake cable bodies are uniformly stressed and are easy to form, light in weight, resistant to chemical corrosion, good in weather resistance and low in production cost; the annular belt is arranged at the end part of the brake cable body and used for fixing the brake cable with a handle, so that the brake cable cannot be separated from the handle and the driving safety is guaranteed.
Description
Technical field
The present invention relates to a kind of braking string, for bicycle brake system.Belong to bicycle accessories field.
Background technique
Bicycle brake system comprises brake lever, braking string, the accessories such as brake binder, before the brake system of prior art is typically provided with one, one latter two braking string and corresponding with it two brake levers and two brake binders, braking string easily ruptures in use for some time, cause brake failure, potential safety hazard is higher, for solving the problems of the technologies described above the two-wire brake system needing use two front brake fares and two rear brake fares, two front brake fares of this brake system need length consistent, two braking string body uniform force during to ensure to brake, but two separate braking string bodies cannot ensure that length is consistent, also there is certain difficulty in assembling.
Existing braking string body is made up of the hollow tubular of outside rubber and the steel wire of inside simultaneously, and its insufficient strength is high, and resistance to chemical corrosion is poor, and weatherability is bad, and cost of production is higher; The end of existing braking string be a hook for fixed handle, after service time is longer, hook can be out of shape, and braking string and handle so can be caused to throw off, thus brake failure, is prone to accidents.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of braking string, the internal lining pipe of this braking string ensures that two braking string are isometric, two braking string body uniform force when ensureing to brake; Simultaneously braking string this body formed simple, quality is light, resistance to chemical attack, good weatherability, cost of production are low, and ensure that traffic safety.
The object of the present invention is achieved like this:
A kind of braking string, be characterized in: the internal lining pipe that described braking string comprises surrounding layer, two side by side parallel are arranged and two are wound around springs, the length of two internal lining pipes is equal, braking string body is provided with in described internal lining pipe, two are wound around the outer wall that spring is wrapped in internal lining pipe respectively, surrounding layer is coated on two and is wound around outside spring, and described braking string body comprises the carbon fiber heart yearn group of internal layer and outer field resin layer, and the end of described braking string body is provided with endless belt.
A kind of braking string of the present invention, its carbon fiber heart yearn group is made up of multi-beam carbon-fiber heart yearn, comprises 1000 ~ 200000 carbon fibers in every a branch of carbon fiber core, and the diameter of every root carbon fiber is 5 ~ 15 microns.
A kind of braking string of the present invention, its resin layer is that polyamide 6 or polyamide 66 or PPTA resinous layer material are made.
Compared with prior art, the invention has the beneficial effects as follows:
A kind of braking string of the present invention, its internal lining pipe ensures that two braking string bodies are isometric, two braking string body uniform force when ensureing to brake; A kind of braking string of the present invention, its braking string body is made carbon fiber heart yearn group and is coated on the resin layer outside carbon fiber heart yearn group, obtained braking string this body formed simple, quality is light, resistance to chemical attack, good weatherability, cost of production are low; Braking string end is provided with an endless belt, fixing for braking string and handle, and therefore braking string can not be thrown off with handle, ensure that traffic safety.

Embodiment
See Fig. 1, the present invention relates to a kind of braking string, comprise internal lining pipe 2 and two winding springs 3 of surrounding layer 1, two side by side parallel settings, the length of two internal lining pipes 2 is equal, braking string body 4 is provided with in described internal lining pipe 2, two are wound around the outer wall that spring 3 is wrapped in internal lining pipe 2 respectively, and surrounding layer 1 is coated on two and is wound around outside spring 3.
See Fig. 2-3, described braking string body 4 comprises carbon fiber heart yearn group 4.1 and the outer field resin layer 4.2 of internal layer, described carbon fiber heart yearn group 4.1 is made up of multi-beam carbon-fiber heart yearn, 1000 ~ 200000 carbon fibers are comprised in every a branch of carbon fiber core, the diameter of every root carbon fiber is 5 ~ 15 microns, described resin layer 4.2 is preferably by PA6(polyamide 6), PA66(polyamide 66) and PPA(PPTA resin layer) the good resin material of weatherability makes, to improve braking string working life.
See Fig. 4, the end of described braking string body 4 is provided with endless belt 5.
Braking string body 4 of the present invention once-through, in the process of preparation braking string body, the head of extruder, through a branch of continuous print carbon fiber, makes braking string body 4 from the resin layer 4.2 carbon fiber heart yearn group 4.1 that is coated on tightly of extruder molten state out.
The diameter of carbon fiber heart yearn group 4.1 can control for the hauling speed of drawing carbon fiber heart yearn tractor by regulating, and then according to required length, continuous print braking string body is sheared.
The density of carbon fiber heart yearn group 4.1 of the present invention is low, and it is 1.76 ~ 1.8g/cm
3, and traditional stainless density as braking string body is 7.5 ~ 8g/cm
3, carbon fiber heart yearn has high specific strength simultaneously, and make the braking string of same thickness, the intensity of carbon fiber heart yearn is far above stainless intensity, and weight is 1/4th of stainless steel braking string.
In addition, the resistance to chemical attack of carbon fiber heart yearn, good weatherability, low cost of manufacture.
Installation process: inserted in two internal lining pipes be arranged side by side 2 respectively by two braking string bodies 4 during assembling, be then connected with bicycle brake handle one end of two braking string bodies 4, the other end is connected with braking binder of bicycle.The length of two internal lining pipes 2 unanimously can ensure that braking string body 4 length is consistent, two braking string body uniform force when braking, and this structure is more convenient at fit on compared with two separate internal lining pipes, and profile is cleaner and tidier, attractive in appearance.
