Through daily observation, it is not difficult to find that the spokes on many car wheels on the market are odd-numbered, and even-numbered spokes are only present in a few models, such as the 4-spoke Paladin and the 10-spoke Audi A6L. Among them, the 10-spoke wheels are still There are dual 5-spoke designs, such as the BMW 7 Series. They seem to have 10 spokes, but in fact they use a 2×5 manufacturing process to avoid placing the two opposite spokes on the same horizontal line.
Then, there may be questions from car owners, why do not manufacturers like to use even-numbered spokes on the wheel rim design?
Assuming that the number of spokes on the rim is an even number, and the angles and lengths between the spokes and the spokes are equal, then the rim is a symmetrical figure. When the two spokes are on the same horizontal line, the rim is subjected to excessive internal stress. The vibrations between each other are transmitted to each other, and resonance occurs, and the wheel rim is prone to deformation or cracking, and the comfort is also poor.
Odd-numbered wheels are not on the same horizontal line, so the internal stress is relieved, the probability of deformation is greatly reduced, and various factors such as wear resistance and comfort are better than even-numbered spokes.
What should I pay attention to when changing wheels? Does the more spokes mean the better the rim?
Some car owners think that the more spokes, the stronger the load-bearing capacity of the rim. In fact, this is not the case. As long as the rim is in compliance with the mechanics, whether it has ten or three spokes, it can guarantee load-bearing. The number of spokes is more due to the appearance. problem. And from the perspective of heat dissipation, under the premise of the same material, the heat dissipation effect of fewer spokes is better than that of multiple spokes. Finally, the complex structure of the wheel rim is not easy to clean, so it is common to refuse to wash or overcharge when washing the car.
At present, there are more and more manufacturers adopting even-numbered spokes on the market, but the best and most common design is still odd-numbered spokes, especially 5-spoke wheels. So what should I pay attention to when changing wheels? In fact, as long as the production process is mature enough and the odd or even spokes are very safe, the only consideration for rim design is aesthetics.
