Description
Technical field
The present invention relates to and be a kind ofly installed in wheel rim on bicycle and manufacture method thereof.
Background technology
Bicycle, in the society in modern times, is the quite general vehicle, is also a kind of equipment of motion; In order to allow rider can drive advance easily, manufacturer can use higher-priced carbon fibre materials to make bicycle, reaches weight-saving effect, and carbon fibre rim is light except the more general aluminum of weight, also has higher intensity.
But general carbon fibre rim, must coordinate special brake skin, if use the brake skin of aluminium rim, meeting is the surface of scratch carbon fiber because braking skin metallic composition; Even if the brake skin using carbon fiber special, in the process of brake, because direct and brake skin friction, carbon fibre rim is likely allowed to cause distortion because temperature is too high.
In order to reduce the temperature of carbon fibre rim, the carbon fibre rim commonly used, metallic material can be increased in the process manufacturing carbon fibre rim, or increase louvre, but these all can affect weight and the intensity of carbon fiber, not only allow the advantage of carbon fibre materials reduce, also reduce the wish that customer buys, real in being necessary the problem improved.
Summary of the invention
Main purpose of the present invention is to provide a kind of bicycle rim, and this bicycle rim can either improve the shortcoming that carbon fibre rim is out of shape because of high temperature, can also keep its weight-saving characteristic.
For reaching above-mentioned purpose, the present invention by the following technical solutions:
A kind of bicycle rim, comprises:
A wheel rim, this wheel rim is carbon fibre materials, and this wheel rim has two corresponding brake limits, and these two brake limit outer rims have the electrodeposited coating of metal.
The metal of described plating is nickel.
A manufacture method for above-mentioned bicycle rim, the method includes the steps of:
Die forming: carbon cloth is coated on hot forming on mould;
Alligatoring: after taking off the carbon cloth of shaping, does milled processed, to remove the resin of excess surface the carbon cloth surface for plating;
Plating: in the surperficial layer overlay metal of carbon cloth.
In the above-mentioned methods, when after milled processed, the surface of the carbon cloth for plating is brushed again the conductive layer of one deck tool electric conductivity.
After having electroplated, the process of mending soil is carried out on the carbon cloth of shaping surface, and has brushed one deck resin again, made its surfacing smooth.
The invention has the advantages that:
Bicycle rim provided by the present invention, electroplate last layer metals by the mode of plating on two brake limits, avoid brake skin and carbon fiber surface direct friction, and produce high temperature, reach the effect reducing carbon fibre rim temperature, and do not increase too much weight again.So the present invention improves the defect of carbon fibre rim for a long time effectively, allow and use people of the present invention, can enough enjoy the advantage of carbon fibre rim with being without fear of an attack from the rear.

Detailed description of the invention
Effect that architectural feature of the present invention and expection thereof are reached will be described with preferred embodiment below, so and be not used to limit the category of the present invention institute for protection, conjunction is first chatted bright.
Please refer to Fig. 1 to Fig. 3, for bicycle rim of the present invention, comprise wheel rim 1, this wheel rim is carbon fibre materials, this wheel rim 1 has two corresponding brake limits 11, and these two brake limits, for the brake skin contact friction of bicycle, can produce heat in the process due to friction, by converting kinetic energy to heat energy, reach the effect of deceleration; These two brake limit 11 outer rims have the electrodeposited coating 111 of metal, as shown in Figure 3A.
The manufacture method of bicycle rim of the present invention comprises following steps:
Die forming: use the male and female mould with corresponding shape, male mould is brushed one deck resin, one deck resin is brushed again after carbon cloth coating being got on, finally master tooling is covered also pressurized, heated and make its closely sealed shaping, wherein, the pressuring method of balloon aeration also can be used to be attached on mould to make carbon cloth; Male and female die surface scribbles off-shape agent, so carbon cloth can not stick on mould;
Alligatoring: after taking off the carbon cloth of shaping, does milled processed, to remove the resin of carbon cloth excess surface the surface for plating, allow surface cleaning, better one, can on the surface that need not electroplate brush one deck resin again, guarantee that this surface can not plate metal and increase unnecessary weight;
Plating: surperficial layer overlay metal wish electroplated by the mode of metallide;
Mend soil: after having electroplated, the process of mending soil is carried out on the carbon cloth of shaping surface, and brushes one deck resin again, increase its hardness, also can grind once again, make its surfacing smooth, also there is effect attractive in appearance.
Because metallide must be just can use under material is the situation of conductor, because resin is not conductor, so in the process of alligatoring, mainly the resin being attached to carbon fiber surface is ground off, avoid the effect affecting metallide; Wherein, carbon cloth is formed by the carbon fiber knit of a lot of strip, the seam of every bar has gap, or difference of height, these are all the places that cannot be ground to, so, can at the conductive layer being brushed one deck conducting resinl or other tool conductive effects by surfacing again, increase the electric conductivity on surface, guarantee the effect of electroplating; In preferably situation, can use the electroless plating without electrolysis, because electroless plating can be plated on non-conductive material, and coating is very even, and pore-solids ratio is also low, is well suited for being used in the present invention.
General carbon fibre rim, the distortion on carbon fiber structural can be caused because braking the high temperature that produce, so the present invention is by the surperficial layer overlay metal of mode on brake limit of plating, the brake skin of bicycle directly can not be contacted with carbon fiber surface, can in the process of brake, reduce conduction to the heat energy of wheel rim, wherein, after tire runs over for a long time, the temperature of tire can raise, so also can electroplate at the contact surface of wheel rim and tire, go to avoid tire heat conduction to wheel rim, also effectively can reduce the temperature of wheel rim; And the metal that the present embodiment is electroplated is nickel, except increasing wheel rim resistance to abrasion, also there is anti-corrosion effect, as other metallic materials will be used, as chromium, copper etc., or use alloy plating to increase the electrodeposited coating on brake surface, limit, also without can not.
The present invention plates layer of metal carbon fiber surface, does not allow brake skin directly contact with carbon fiber surface, so user need not buy more the expensive special brake skin of carbon fiber again, and general brake skin just can use, and does not also have the puzzlement of scratch; Also because only have plating brake limit, weight can not be increased to carbon fibre rim, and allow carbon fiber can keep the characteristic of lightweight and high strength.
Sum up above embodiment, bicycle rim provided by the present invention, brake limit is allowed to plate layer of metal by the mode of plating, avoid carbon fiber surface directly with the friction of brake skin, cause the temperature of wheel rim too high and be out of shape, and the material on brake limit is not carbon fiber, the present invention that just can arrange in pairs or groups uses common brake skin; So the present invention improves the defect of carbon fibre rim for a long time effectively, allowing and use people of the present invention, can enough enjoy the advantage of carbon fibre rim with being without fear of an attack from the rear, is have progressive effect in fact.
