a hub material
The hub can be divided into two categories according to the material: steel wheels, alloy wheels.
The main advantage is a steel wheel manufacturing process is simple, relatively low cost, strong resistance to metal fatigue. But the disadvantage is also obvious, such as large weight, large inertial resistance, poor heat dissipation and the like.
2-alloy wheels the advantage of light weight, high manufacturing precision, high strength, low inertial resistance, heat capacity, visual effects, etc., the disadvantage is the manufacturing process is complicated and costly.
Multi-alloy wheels aluminum as a base material, an appropriate manganese, magnesium, chromium, titanium and other metal elements together. And compared to steel wheels, alloy wheels with energy saving, safety and comfort features, so more and more cars have the alloy wheels as standard equipment. Here we take a look at the three major characteristics of the alloy wheels.
1 light energy alloy wheels weight, high manufacturing precision, small deformation during high speed rotation, a small inertial resistance, thus benefit straight running performance, reduce the tire rolling resistance thus reducing fuel consumption.
2 security thermal conductivity is three times the steel alloy, the heat dissipation effect is very good, thereby enhancing the braking performance, and improve the service life of the tire brake disc, effectively protect the safety of car driving.
3 fitted with alloy wheels comfort automobiles generally used cushioning and shock-absorbing performance than a normal tire flat tire so that the car on uneven roads or high speed, greatly improving comfort.
