Nowadays, more and more
Used Car are entering the market, ranging from mini-cars, hatchbacks, sedans to SUVs to MPVs, and models of all levels are covered.
After learning about many models, no matter which manufacturer produces the
Used Electric Car, the material of the shoes worn by the manufacturer for their products is the same, and the aluminum alloy wheels are all the same.
Why do manufacturers use aluminum alloy wheels for Used Car instead of relatively cheaper steel wheels? What are the advantages of aluminum alloy wheels?
1. First look at the steel hub
Advantages: simple manufacturing process, relatively low cost, strong resistance to metal fatigue.
Disadvantages: heavy weight, large inertial resistance, poor heat dissipation, etc.
2. Look at the aluminum alloy wheels
Advantages: light weight, high manufacturing precision, high strength, small inertial resistance, strong heat dissipation, good visual effects, etc.
Disadvantages: The manufacturing process is relatively complicated and the cost is high.
From the above comparison of advantages and disadvantages, we can see that the most direct advantage of aluminum alloy wheels is light weight. Generally, aluminum alloy wheels are 2 kilograms lighter than steel wheels on average, and 4 wheels in a car save 8 kilograms in weight. We can all understand that the heavier the vehicle, the higher the energy consumption, and the lighter the weight, the less energy consumption. For Used
Electric Car, the less energy consumption, the longer the cruising range of the vehicle.
Next, let`s talk about good heat dissipation. At 20 degrees Celsius, the thermal conductivity of aluminum alloy is 0.53, while that of steel is 0.18. It can be seen that the thermal conductivity of aluminum alloy is three times that of steel. Moreover, the heat dissipation effect is good, and it can also keep the tires at an appropriate temperature during long-term high-speed driving, so that the brake drums and tires are not easy to age, increase the service life, and reduce the chance of tire blowout.
And the most important thing is aesthetics. Generally, steel wheels are limited by production, and the form is monotonous and dull, lacking in changes. Aluminum alloy wheels have various designs, and the effects of luster and color also improve the appearance of the car. sense of value and beauty.
In fact, aluminum alloy wheels have some advantages that are invisible to the eyes, that is, they can increase driving stability. Due to the light weight of aluminum alloy wheels and high manufacturing precision (high roundness), the steering wheel is stable in vehicle operation, with less jump, light and flexible when turning, and relatively easy to brake.
