Description
Technical field
The utility model relates to a kind of vehicle, specifically relates to a kind of bicycle wheel rim made of carbon fibre of perfect heat-dissipating and with the bicycle of this wheel rim.
Background technology
Raising along with people's living standard, the demand of high-grade bicycle is more and more, cycle racing is more and more universal, people start to pursue the lighter and handier instrument of riding, carbon fiber composite material is due to its light and strong feature, be applicable to very much manufacturing weight-saving bicycle, at present, the trend of " the carbon fibrillation " of high-grade bicycle is more obviously aobvious
Yet a technical barrier who manufactures carbon fiber wheels, be: the friction resistance to effect of heat that how to improve wheel rim.Ultimate attainment for the lightweight of racing car is pursued, the players of road race is substantially all ready to use the racing car of V braking, and this car is to produce braking force by being arranged on the cliding friction at the braking mark position of friction shoe on binder and wheel rim.The wheel rim of making for metallic materials such as aluminum alloys, because the fusing point of metallic material own is high, resistance to heat is good, and permeability of heat is good in addition, fricative heat has dissipated soon, thereby can not produce the gathering of heat and temperature is risen so high, affects the intensity of wheel rim.But for resin matrix composite, situation is just different.The resistance to effect of heat of carbon fiber itself is fine, and its temperature tolerance has even surpassed iron and steel, and carbon fiber is at the temperature of 1000 degrees Celsius of left and right, and the loss rate of the physico mechanical characteristics such as intensity will be far smaller than the loss rate of iron and steel.But fiber resin matrix (for carbon fiber composite material, the overwhelming majority is epoxy systems) Tg softening point is around all 100～150 degrees Celsius of left and right.Facing some long sections apart from heavy grade, the temperature arrising caused by friction power of wheel rim and brake shoes sharply increases, and the programming rate of wheel rim is also sharply accelerated.Epoxy resin has started softening and has lost intensity in 100 about degree, lose the support of resin matrix, carbon fiber composite material wheel rim has also lost intensity, thereby cannot be supported on the load that tire pressure and player's body weight are brought, there is even fracture of distortion, player's safety is caused to great threat.
It is fast that current existing carbon fiber composite material opening wheel rim ubiquity programming rate, and wheel rim high temperature loses the situation of intensity (pipe tyre bead fractures, the broken ring distortion that pops).This problem has also restricted the universal of carbon fibre rim.
Also the existence of this problem just, just there is people then look for second solution, the interior ring of wheel rim is made of carbon fiber, the part of brake frame is still made of aluminum alloy materials, although the weight outline of whole wheel rim is higher than the wheel rim of full carbon, but the wheel rim of this " half carbon " has been taken into account the lightweight of carbon fiber and the friction resistance to effect of heat of aluminium circle, a kind of good " compromise " scheme of can yet be regarded as.
In order to improve the friction heat resistance of full carbon fibre rim, many carbon fiber wheels manufacturer is used the epoxy-resin systems of high Tg (resin sinter point) temperature, improves the temperature tolerance of goods.Practice shows, does like this and really can improve the certain heat resistance of wheel rim, but use the carbon fiber prepreg of this high-Tg resin, and hardness is large at normal temperatures, should not bend distortion, to the laying operation under normal temperature, has brought great difficulty; This resin flowing power is at high temperature not good yet simultaneously, bubble in resin also should not be discharged, thereby caused the increase of material internal void content, the increase of void content has worsened the heat conducting condition of material, thereby also weakened high-temperature resin (high Tg resin), improve durothermic effect.
Application publication number is that the patent documentation of CN102795053A discloses a kind of bicycle rim, comprises: a wheel rim, and this wheel rim is carbon fiber material, and this wheel rim has two corresponding brake limits, and these two brake limit outer rims have the electrodeposited coating of metal.The document is electroplated last layer metals on these two brake limits, allow brake rubber block not with carbon fiber surface direct friction, be to completely cut off the friction between brake shoes and carbon fiber with coat of metal, maintain the intensity of carbon fiber composite material.But, in above-mentioned bicycle rim use procedure, not solving the low problem of carbon fibre rim brake resistance to effect of heat, intensity cannot guarantee.And the brake limit that CN102795053A is used needs first by after the carbon fiber composite material curing molding on brake limit, re-plating layer of metal, then by the brake limit of having plated metal again with carbon fibre rim secondary bonding, cause electrodeposited coating and the carbon fiber rim main body binding strength of metal low, after long-term use, easily come off.
