Product Description:

Wheels and rims, treads, tire bell, is within the tire profile support the barrel of the tire mounted on the shaft, the center of metal parts. Wheels according to different diameter, width, forming method and material are varied.

Wheel hub is introduced

Within the tire itself is software, tire profile support the barrel of the tire, the center is mounted on the shaft parts is called "wheel".

The diameter of the same, but the width is not the same, has the opposite, but the two data are different wheel, suitable for different tyres. Someone think original tires are senior enough, want to upgrade, tend to be widened, the reduction of flat change ratio, increase the diameter, material, at this time, if must change the wheel hub, is called modified hub.

Car wheel hub bearing in the past the most were using single row tapered roller or ball bearing in pairs. With the development of technology, cars are already widely used car wheel hub unit. The use of the wheel hub bearing unit and usage is growing, has developed the third generation: the first generation consists of double row angular contact bearings. Roll out the second generation of road have a fixed flange is used to bearing, can be simple to bearing sleeve on the shaft with a nut. Make car maintenance becomes easy. The third generation wheel hub bearing unit is adopted the bearing unit and the holding brake system. Wheel hub unit designed to have the flange and the outer flange, the flange bolts fixed on the driven shaft, the bearing outer flange be installed together.

2 wheel type

Hub and wheel rim. According to the characteristics and requirements of different models, the wheel hub surface treatment would take a different approach, can be roughly divided into the lacquer that bake and electricity

Wheel hub two plating.

Ordinary car wheel hub in the consideration on the appearance of small, good heat dissipation is a basic requirement, technology adopted in the basic treatment of the lacquer that bake, namely first spray and electric baking, cost is economic and the colour is beautiful, keep long time, even if scrappage, the color of the wheel hub remains unchanged. Many popular car wheel hub surface treatment process is the lacquer that bake, such as santana 2000, xiali criteria, bigchina info-net, southeast lancer or Honda Odyssey. Some fashionable avant-courier, movement is the lacquer that bake techniques used the color wheel. This kind of wheel hub moderate price, complete specifications.

Plating wheel, electroplating, water electroplating and pure silver plating type, etc. Electroplating silver plating and water wheel, though bright color and vivid, but keep time is shorter, so the price is relatively cheap, for many young people like the pursuit of novelty, the market price is in 300 yuan - 500 yuan between. Pure plating wheel hub, such as Shanghai gm buick model of original factory production of form a complete set of is pure plating wheel, hold time long color, is premium. High-grade cars such as arose, audi choose pure plating wheel, more cost about RMB 800-900.

Wheel hub classification

The editor

Wheel according to the material can be divided into two broad categories: steel wheel, alloy wheels.

On the market at present the original wheel according to the material can be divided into steel wheel and alloy wheels, both have pros and cons of each.

Steel wheel hub of the main advantages is the manufacturing process is simple, the cost is relatively low, and metal fatigue resistance ability is very strong, also is our common cheap and sturdy. But the shortcomings of your steel wheels are relatively prominent is ugly (can say nothing to speak of appearance), heavy weight (the same wheel steel quality are much heavier than aluminum alloy material), big inertia resistance, heat dissipation is more bad, and very easy to rust.

And relatively, material alloy wheels can compensate for this problem, lighter weight, small inertia resistance, production of high precision, rotating at high speed when the deformation of small, small inertia resistance, is conducive to improve the performance of the car straight reduce tire rolling resistance, thereby reducing the fuel consumption. Alloy thermal conductivity is about three times that of steel material, good heat dissipation, for the vehicle brake system, tires and braking system of the thermal decay can play a role. Factory car alloy wheels are on the market at present is given priority to with aluminium alloy, of course, a lot of modified wheel in order to achieve certain special requirements and visual ascension will choose chrome, titanium and other elements as basic material. However, compared to steel quality, and the wheel, the alloy wheels prices a lot more expensive, so often in a lot of mid-range levels of the original car, steel wheel match models appear in low, and alloy wheels is high match the standard model.
