The world's automotive industry is developing in the direction of light weight, high speed, safety, energy saving, comfort and light environmental pollution, and the consumption of automotive aluminum alloy parts is increasing day by day. As one of the important components of the automobile drive system, the wheel is also a kind of component with high safety requirements. It not only carries the weight of the automobile, but also reflects the appearance of the automobile. In the past 10 years, the average annual growth rate of global aluminum alloy wheel production has been 7.6%. With the increasing demand for lightweight automobiles, aluminum alloy wheels are gradually replacing traditional steel wheels and are widely promoted and used in the modern automobile manufacturing industry. It is usually produced by casting or die-casting. Traditional casting methods include differential pressure casting, low pressure casting and gravity casting. Due to the pressure-filled high-speed turbulent movement of the alloy liquid, the gas cannot be discharged in the cavity, resulting in the product blank organization structure is not dense. Compared with the traditional round rod cutting process, the method of upsetting the prefabricated billet can reduce the process of upsetting the round rod and the prefabricated billet in the conventional forging of aluminum alloy wheels, reduce the production process, reduce energy consumption, and improve production efficiency.

Buying a car is a normal thing for many people.But after buying a car and going home, it will always be dirty as time goes by, and you need to wash the car when it is dirty.Car wash shops are places that car owners visit every month. Of course, some car owners like to wash their cars at home and buy a lot of car wash tools. Many consumers will find that when they wash their cars, there is a place in the car that can't be washed cleanly.This place is the wheel rim of the tire, which is the support accessory of the tire. Because it is relatively close to the ground, it is easier to stick to dust and get dirty. If it is not cleaned for a long time, the wheel rim will get dirtier and dirtier, which is very uncomfortable to look at. To clean up these stains, we need to use a special wheel cleaning agent.We first touch the wheel cleaning agent evenly on the wheel rim, and after waiting for a few minutes, we can easily wipe the stains on the tire with a towel.For the stains deep in the wheel rim, we can use a small toothbrush to clean it slowly.Or if you want to clean up thoroughly, you can also remove the tires. After removing the tires, you can clean the wheels more conveniently and comprehensively.

Many car owners like to drive faster and feel very irritating. Even on uneven roads, they don't speed up. However, this behavior can be very damaging to the wheels of the car.Especially for explosion-proof tires with a low flatness ratio, not only is the tire wall thin, but it is also very hard. When this kind of tire is subjected to a strong impact, the force will be directly transmitted to it, resulting in its loss of roundness, so how to judge its loss of roundness? If it is out of roundness, the driver's more direct feeling is that the car deviates while driving, and the body and steering wheel will shake severely, and even the degree will increase with the increase of the speed.In addition, if it loses its roundness, it will also cause a great impact on the chassis suspension, and in severe cases, it will cause deformation or even fracture of the control arms of the suspension. Since most of the materials used to make it are made of aluminum alloy, it is difficult to repair if there is a loss of roundness. Even if the repair is completed, it will not be able to reach the better state when it left the factory. .Therefore, when this happens, try to do special wheel repair as much as possible, but generally if it is out of roundness, it is recommended to replace it directly, in order to avoid some accidents when the owner is driving.

If you encounter a situation where the car tire is pierced with a small nail and taken off but there is no air leakage, it doesn't matter, we can not repair it.But we need to carry out testing. We can't just ignore it if it looks like there is no air leakage to the naked eye, but we can continue to use it after we are truly sure that there is no air leakage. It doesn't matter that the car tire is stuck to the nail at any time. After the car is stuck to the nail, the test found that it is not leaking, and it has not affected the overall structure of the tire.At this time, the tires can still continue to be used.Because the material of automobile tires is generally thicker, generally only the nails will leak after they are completely pierced. If the nails are relatively small, the length is short, and the important parts of the tire are not damaged, it will generally not cause the tire to leak, so we can judge according to the actual situation. 1. If the tire of the car is stuck while driving on the road, we need to pay attention. It is best to pull over and park in a safe place, and then see if the tire leaks. If there is no leak, it will not have much effect, but if there is a leak, it is not recommended to continue driving. 2. If the air leakage is not too serious, we can drive slowly to a nearby repair factory or 4s shop for repair.There are two general ways to repair a tire, one is to repair a tire with mushroom nails, and the other is to repair a tire with rubber strips.We can choose the appropriate tire repair method according to the actual situation. 3. If the air leakage is more serious, we can only wait for rescue on the side of the road.You can call the roadside assistance number or contact the repair factory, 4s shop, and.In this way, there will be special staff to carry out repairs or after the trailer arrives at the store, the repairs will be carried out.

After decades of development, China's automobile industry has become an important industry in the national economy. With the progress of technology and the improvement of various performance indicators of automobiles, governments of various countries have become more and more stringent requirements for energy conservation and environmental protection. Therefore, automobile lightweight has become the main direction of automobile development. Generally, the weight of auto parts can be reduced by 1%, which can save 1% of fuel. For every 1% reduction in the weight of moving parts, fuel can be saved by 20%. Automobile wheels are parts installed on automobiles to support tires, and they are also one of the important moving parts of automobiles. Carbon fiber automobile wheels are manufactured by parting molding or material preforming process, and the thickness of the product after the mold is partially uneven: in order to maintain the integrity of the carbon fiber fiber, the uneven thickness cannot be processed and finished like metal materials. If it is a carbon fiber composite material, the screw holes are installed and worn, causing installation balance problems, affecting driving and safety. In addition, the two-piece carbon fiber hub needs to be locked at the hub lock and spoke screws. If the screws are removed, the carbon fiber screw holes will wear out, which will not meet the locking requirements and affect the driving safety of the car. The thickness of the yarn layer is 0.2-1mm, the carbon fiber spokes are formed by hollow blow molding, the thickness of the spokes is 6mm-20mm, and the filling sealant is glue that is cured at high temperature.

For many people, modifying wheels is like changing shoes, just like changing shoes. “The ball doesn't have to be played well, but there must be shoes."The car doesn't have to run fast, but the wheels must look good!"Indeed, a good set of wheels can indeed change the “temperament” and even performance of a car. The wheels of each brand and type of vehicle are different.The wheels slowly changed from the single shape of Z to a diverse style.From casting to forging, the weight has become lighter and lighter.Some wheels are very traditional and look very sturdy.Some wheels have many hollow parts in the middle.You can see large brake discs and brake calipers.Therefore, some people are beginning to worry about whether the hollow hub with increased thin spokes will be unsafe and whether the strength will be reduced? First, we need to clarify the components of the hub. Spokes and rims Spokes are the parts we usually see with the naked eye.Different wheels of different brands often have their own games in the spokes, different shapes, but the strength has nothing to do with it. The spokes mainly play a role in improving the appearance level.The rims directly carry the weight of the car, and the strength of the hub plays a decisive role.

The wheel is made into a circle and the characteristics of the circle are closely related, and the distance from the center of the circle to any point on the circle is equal.The wheel is circular. The axle is pressed on the center of the circle, and the wheel rolls on the ground. The distance between the axle and the ground is always the radius of the wheel. As long as the road is relatively flat, the vehicle will be more stable. . The circle has a faster rolling force, and it is relatively stable to roll. If the wheel is round, the contact area with the ground will be greatly reduced, and it will be easier and faster to roll.If the wheel is square or triangular, the distance from the center of the wheel to the ground is constantly changing, and the vehicle cannot maintain stable driving on the ground. In more science and technology museums, it can be seen that bicycles with square wheels on specially-made tracks pass by very smoothly without obvious bumps.As for why such wheels can also be square and so stable, this is because the track has been specially designed. This track is uneven, which just makes up for the inconsistency in the height between the center of the square wheel and the ground, so it will not be bumpy when driving.

The use of cars has brought great convenience to our travel. However, during use, when abnormal conditions occur, such as common car wheel damage, we must be vigilant and go to a formal repair shop for repairs as soon as possible to ensure the normal performance of the car.Otherwise, it will easily cause us inconvenience and may also affect our travel safety. During the driving process of the vehicle, it is easy to rub against the road, but if we pay more attention during the driving process, the occurrence of this situation can be greatly reduced. However, if there is deformation, the owner needs to send it to a professional repair shop for repair in time. Repairs must be professional and standardized. When repairing car wheels, we found a regular repair workshop for repairs to ensure that the performance of the wheels is restored and will not affect our normal travel. Therefore, we pay attention to it and can no longer be careless and affect the performance of the vehicle. For the maintenance of automobile wheel wear and tear, some use aluminum alloy dissolving welding technology to fill the wheel defects with aluminum alloy, which completely solves the shortcomings of atomic ash as a filler and ensures the maintenance quality of the wheel. The repair techniques of different repair shops are also different. We pay attention to wheel repair and choose a reliable repair shop to reduce unnecessary trouble and truly repair the wheels without adversely affecting the performance of our cars.

The wheel hub is a very important part of the car wheel.Good wheels not only look good in appearance, but also have excellent performance.It is one of the important projects in the car modification project.Today I will talk to you about the repair method of aluminum alloy wheels. 1.The wheels should be cleaned regularly, and after cleaning, the wheels should be waxed and maintained to keep their luster forever. 2.The temperature of the wheel hub is relatively high.In order to cool and clean naturally, do not wash with cold water, otherwise it will damage the aluminum alloy wheels and even deform the brake discs, affecting the braking effect.Cleaning aluminum alloy wheels with detergent at high temperatures will cause chemical reactions on the surface of the wheels, lose their luster, and affect the beauty of the wheels. 3.If the location of the vehicle is humid, the wheels should be cleaned frequently to avoid salt from corroding the surface of the aluminum alloy wheels. 4.When the surface of the wheel hub is stained with asphalt that is difficult to remove, general cleaners will not help.You can try to remove it with a brush.Do not use hard brushes, especially iron brushes, so as not to damage the surface of the wheel hub. In fact, the maintenance of car wheels is very simple.You can fully operate and protect the wheels at home.In fact, it is to protect the feet on the car and extend its service life.Wheel repair experts said that only in this way can you run more easily and farther.

Tire pressure is an issue that car owners should always pay attention to, but some car owners may think that they are buying tires from big brands, such as Michelin, Goodyear, Bridgestone, Dunlop and other international brands of tires, so the quality can be guaranteed.Even if the tires are out of gas, it should be fine to drive as usual.And this idea is wrong, and there are countless accidents caused by lack of air. 1.When the tire pressure is lower than the normal value, the tire will soften, and the deformation will increase. Once the contact area between the tire and the road surface increases, the friction coefficient will increase exponentially, causing the tire temperature to rise sharply. In this case, if the car is still driving at high speed, the heat will quickly gather together, and the inside of the tire will begin to separate and delaminate, causing the tire to burst.If the car is driving at low speed, the tire will be injured due to excessive tire deformation.The latter situation is more dangerous due to the long incubation period and high concealment. It lays a hidden danger for the tire to burst when driving on the highway in the future. 2.Due to the excessive deformation of the carcass caused by the lack of air in the tire, it is prone to cord fracture or even faults, which can cause the tire zipper tire to burst in severe cases. “Air pressure is the life of the tire, and high temperature is the main killer of the tire”" This sentence is not excessive at all.If the tire pressure is 20 percent lower than the normal value, the life of the tire will be reduced by 30 percent, reaching a critical point that endangers safe driving.Therefore, in addition to doing a good job of tire maintenance, drivers should also pay attention to checking the tire pressure, keeping the tires under standard air pressure, and ensuring driving safety.

1. High temperature Frequent flat tires in summer have a lot to do with the high temperature in summer.Because, once the road surface temperature rises, the friction between the tire and the road surface causes the tire surface temperature to be very hot.Under thermal expansion and contraction, the tire carcass rises and thins, and then it can easily lead to a flat tire. 2. Overload In China, it is relatively common for freight cars to be overloaded, and it can almost be said that no truck is not overloaded.This is why the flat tire rate of trucks remains high, because when the actual load of the car exceeds the large allowable load of the wheels, a flat tire will occur. 3. Bad road conditions This is the same as the reason for the wear of one's own shoes.With the same pair of shoes, walking on uneven roads will of course wear out faster than walking on flat roads.Moreover, at high speed, the tire can easily be hit by sharp objects on the road and cause a flat tire. 4. High speed Many people don't understand that speeding can also cause a flat tire, and think it is unlikely.In fact, the possibility of a flat tire overspeed is very high.Because excessive speeding for a long time will cause the tire temperature to rise rapidly, which will cause the rubber to age rapidly and the tire to burst. 5. The air pressure does not meet Both too high and too low tire pressure can cause a flat tire. A tire that is too high is like a balloon filled with too much gas, which can easily cause a flat tire after being squeezed.Tires with low air pressure will cause the contact surface between the tires and the ground to become larger, and the frictional resistance will also become larger when driving. When the car is driving at high speed, the tires heat up quickly, which makes it easier to make the tires high temperature, which is more likely to lead to the discovery of a flat tire. 6. “Work with illness” Tires will cause serious wear and tear after long-term use. If the owner is still using them at this time, it can easily lead to a flat tire.

From the perspective of vehicle performance and driving experience, they can indeed have different effects. Usually, large wheels usually have a more domineering appearance, making the entire body appear more calm and powerful. At the same time, large wheels can also improve driving stability and reduce the tilt of the vehicle when turning, thereby enhancing handling and safety. In addition, large wheels can also improve the load capacity and grip performance of the vehicle. When the tire size is larger, the flattening rate of the tire is relatively small, which means that the contact area between the tire and the road surface is larger and the friction force is greater. This is particularly important for high-speed driving and curve driving, because it will make the vehicle more stable and provide stronger support. But it is worth noting that the big wheels are not perfect. Large wheels will affect the acceleration and braking performance of the vehicle, because the weight and resistance of the wheels will increase. And large wheels are usually noisier than small wheels, which means they produce more tire noise and affect ride comfort. Therefore, when choosing the size of an automobile hub , it is necessary to balance the needs of various aspects and weigh different advantages and disadvantages. And according to the adaptability of the model, choose the appropriate size of the wheels to ensure the stability and comfort of the vehicle.
