Abstract
The invention discloses an aluminum alloy automobile hub and a preparation method thereof. The aluminum alloy automobile hub concretely comprises an aluminum ingot, a silicon element, a magnesium element, a titanium element and a strontium element. The preparation method comprises the steps of fusing the aluminum ingot, then adding the silicon element, the magnesium element, the titanium element and the strontium element into an aluminum solution, and then, preparing a finished product of the automobile hub according to a conventional production process. Due to the implementation of the preparation method, the produced automobile hub product not only is beautiful in appearance, light in weight, good in strength and strong in heat radiation property, but also cannot rust forever and is very specific. In addition, the produced automobile hub product is low in production cost and very wide in market prospect.
Description
Technical field
The invention belongs to a kind of manufacturing technology field of automotive hub, be specifically related to a kind of aluminium alloy automobile hub and preparation method thereof.
Technical background
Wheel hub, English name: WheelHub, WheelHubUnit, in doughnut centered by axle for the cylindrical metal parts of support tire, generally, being exactly the position that wheel center installs axletree, is the important spare part connecting brake drum (retarding disc), wheel disc and semiaxis.
Automotive hub is an important component part of automobile component, and along with the growth of Chinese automobile Parts mapping, wheel hub industry is developed gradually.According to " prediction of Chinese automobile wheel hub industry market is looked forward to the prospect with the report of investment strategy planning application ", data presentation is since 2010, and the macro economic policy based on promote domestic demands, for the stable development of automobile industry provides the foundation and guarantee.From automobile market tendency in 2010, the impact of macro economic policy on automobile market has run through the whole year, annual automobile volume of production and marketing reaches 1826.47 ten thousand and 1806.19 ten thousand respectively, and production and marketing creates the highest again, and continues to keep the first in the world automobile production and country of consumption status.Within 2011, economic continuation keeps steady growth, and automobile production and marketing situation is expected to continue to obtain larger amplification; Within 2011, Chinese automobile output is expected to breakthrough 2,000 ten thousand, within 2015, reaches 2,500 ten thousand.On long terms, the quick growth of China's GDP is that automobile industry provides wide demand space, and the growth with automobile sales volume increases by the demand of automotive hub.A few years from now on Chinese automobile sales volume is expected to sustained, stable growth, for automotive hub industry provides the opportunity of development.
At present, the wheel hub on market can be divided into steel wheel hub and alloy wheel hub according to material, and each have their own pros and cons.
The topmost advantage of steel wheel hub is exactly simple (the general technique adopting casting of manufacturing process, such as aluminium alloy wheel hub generally adopts low-pressure casting process to produce) advantage of lower cost, and anti-metal fatigue is very capable, namely we be commonly called as cheap solid again.But the shortcoming of steel wheel hub is also relatively outstanding is exactly outward appearance ugliness (can say and not have outward appearance to say), weight comparatively large (identical wheel hub steel matter is heavier than aluminum alloy material a lot), inertia resistance is large, and thermal diffusivity is also poor, and is very easy to get rusty.
Alloy material wheel hub just in time can make up such problem, lighter weight, and inertia resistance is little, making precision is high, and the distortion when high-speed rotation is little, and inertia resistance is little, be conducive to the linear driving performance improving automobile, alleviate tire drag, thus decrease oil consumption.The heat conductivility of alloy material is again about three times of steel, and thermal diffusivity is good, and for the braking system of vehicle, the heat fade of tire and breaking system can play a role.
Summary of the invention
Object of the present invention is just to provide brand-new a kind of aluminium alloy automobile hub and preparation method thereof.Specifically comprise: this wheel hub is made up of aluminium ingot, element silicon, magnesium elements, titanium elements, strontium element.Preparation method be above-mentioned aluminium ingot is fused after, then add above-mentioned element silicon, magnesium elements, titanium elements, strontium element toward aluminum solutions, then production technique conveniently prepares automotive hub finished product.By implementing the present invention, not only outward appearance is beautiful, quality is light, intensity good, thermal diffusivity is strong for the automotive hub product produced, and Never-rusty, and product has characteristic.In addition, institute's wheel hub products production cost that steams is low, and market outlook are very wide.
The present invention is achieved through the following technical solutions:
A kind of aluminium alloy automobile hub and preparation method thereof, is in technical scheme: this wheel hub is made up of aluminium ingot, element silicon, magnesium elements, titanium elements, strontium element.
Specifically comprise the steps:
1, raw material composition and proportioning: aluminium ingot 98.835%, element silicon 0.7%, magnesium elements 0.3%, titanium elements 0.15%, strontium element 0.015%.
