With the rapid development of the automobile industry, automobile production and sales volume show a blowout development. At the same time, the automobile industry is gradually developing towards safety, environmental protection, and energy conservation. Under this condition, the application advantages of automobile aluminum alloy wheels gradually show up, which have been widely used in automobile manufacturing, and even become the first choice of materials for automobile wheels.

Weight and fuel consumption

First of all, the quality of the aluminum alloy wheel is 65% lower than that of the traditional steel wheel, which greatly reduces the weight of automobile wheels, thus improving the rotational inertia of the automobile wheels and promoting the effective improvement of automobile acceleration. Take Audi, a high-end car, for example, by using aluminum alloy wheels, the weight of the whole car is reduced by 40%, the acceleration of the car is greatly increased, and the acceleration time of 0.3s is shortened. It can be seen that through the application of aluminum alloy wheels, the driving performance of the car is greatly improved, to optimize the performance of the whole car and meet the needs of consumers.

Secondly, the application of aluminum alloy wheels can not only improve the acceleration of vehicles, but also play a role in saving fuel consumption, greatly improving the fuel efficiency of vehicles, and effectively promoting the energy-saving development of the automobile industry. According to relevant data, ordinary cars can save 0.05L of fuel per 100km after using aluminum alloy wheels. If each car runs 100000 km, it can reduce fuel consumption by about 50L, which can effectively reduce vehicle exhaust emissions.

Improve performance

The production technology level of the aluminum alloy wheel is very high, and it can realize the separation of the wheel and tire so that during the normal driving process of the car, the focus of the car can be stabilized, and the whole body can be prevented from large vibration during the driving process.

As the vibration performance of the aluminum alloy wheel is very strong, the vibration amplitude can be reduced by 12% by replacing the steel wheel with an aluminum alloy wheel. At the same time, in terms of balance, traditional steel hubs need to go through multiple rolling links in the production process, including cold rolled steel, hot rolled steel, spinning, and welding, which greatly reduces the overall balance of steel hubs. When the driving speed of the car is relatively high, the car is prone to vibration and other phenomena, which affect the safety and driving comfort of drivers. However, aluminum alloy hubs have a high level of production technology, Each parameter is accurate, which makes it perform well in terms of balance, and can greatly improve the driving performance, safety, and comfort of the car.

Thermal performance

Due to the fast driving speed of the car, the wheels of the car will have a lot of friction with the ground, which will cause the temperature of the car wheels to rise. When the temperature of the car tires is too high, it is easy to cause problems such as tire explosion, which will threaten the personal safety of drivers and will cause different degrees of damage to the facilities around the car and pedestrians.

When aluminum alloy wheels are used, they will promote the temperature reduction of automobile wheels, mainly because the overall composition of aluminum alloy wheels is more reasonable, and the heat dissipation coefficient is relatively high. Even if the driver repeatedly steps on the brake, the wheel alloy wheels can play a role in rapid heat dissipation, control the temperature of automobile tires within a reasonable range, and prevent tire blowouts and other problems. Relevant data shows that the heat dissipation coefficient of aluminum alloy tires is 2-3 times higher than that of the traditional steel wheel, which shows that the aluminum alloy wheel has obvious advantages in heat dissipation performance.

Improve car comfort and safety

The traditional steel wheel may have deformation problems under high-speed driving conditions. If the car frequently or emergency braking and other measures occur, the temperature of the wheel will rise and the tire explosion rate will be greatly increased. The aluminum alloy wheel, due to its high heat dissipation performance and strong heat conduction performance, will greatly reduce the tire blowout rate, thus providing effective protection for car drivers.

At the same time, the aluminum alloy wheel performs well under automobile braking conditions, which can greatly improve the service life of automobile brake discs and tires, and provide effective protection for automobile safety. Moreover, since most automobile tires with aluminum alloy wheels are flat, their overall shock absorption and buffering properties have been greatly improved. Even on low-lying and uneven roads, drivers will not feel too bumpy, thus effectively ensuring driving safety and comfort.
