Treatment of fracture of automobile hub screw
TIME：2020.01.05
What do you do when the hub screws break? The car wheel hub screw fracture to electric welding repair department out, and then replaced with a new good. If it does not need to remove the wheel replacement screw, some models need to remove the axle head replacement screw, some can be replaced directly. The Hub (Car Rim) is where the Axle is located at the center of the wheel, commonly known as a "Rim" or "Rim. ". The wheel hub is easily stained with dirt, if it is not cleaned for a long time, it may be corroded and deformed, resulting in potential safety hazard. Therefore, special attention should be paid to the maintenance of the wheel hub. According to the material of the wheel hub market can be divided into steel wheels and alloy wheels, and each has its own advantages and disadvantages. The main advantages of steel wheels are their simple manufacturing process (usually by casting, for example, aluminum alloy wheels are usually by low pressure casting) , relatively low cost, and strong resistance to metal fatigue, which is what we call cheap and sturdy. However, the disadvantages of steel wheels are also relatively prominent, that is, they are ugly in appearance (there is no appearance to speak of) , heavy in weight (the same wheel steel material is much heavier than aluminum alloy material) , with high inertia resistance and poor heat dissipation, and it rusts very easily. Alloy wheels can make up for such problems, light weight, small inertia resistance, high manufacturing accuracy, small deformation at high speed rotation, small inertia resistance, is conducive to improving the straight-line driving performance of the car, reducing the rolling resistance of the tires, which reduces fuel consumption. Alloy material thermal conductivity is about three times of steel, good heat dissipation, for the vehicle braking system, tires and braking system of the thermal attenuation can play a role. The original car on the market alloy wheels are mainly aluminum alloy, of course, many modified wheels in order to meet certain special requirements and visual enhancement will choose chromium, titanium and other elements as the basic materials. However, compared with steel wheels, alloy wheels are much more expensive, so often in many low-end level of the original car, steel wheels will appear in the low-matching model, and alloy wheels are high-matching model of the standard.
