How can such a small pillar on the hub of a car bear the weight of a car?

The audi A6 weighs 1,760 kilograms, the mini Cooper 1,145 kilograms, the RAV4 1,420 kilograms and the Toyota corolla 1,300 kilograms. These common four-wheeled cars weighed a ton or two, more than twenty or thirty adults. And the car wheel hub on the four pillars are relatively small, and how to bear the car so heavy weight?


There are three key properties in the study of material mechanics: stiffness is the ability to resist deformation, strength is the ability to resist failure, and stability is the ability to balance materials. At present, the performance and weight of the automobile in the industry are improved, while the bearing capacity of the wheel hub is also the result of comprehensive research and development and continuous progress in the past two hundred years, which is also the perfect performance of the stiffness strength and stability.


Wheel hub manufacturer


In the process of driving the wheel hub than the static environment is more complex, but compared to the horizontal force is not as big as the vertical force, and the movement of the vertical force compared to the static can also be ignored. So for the sake of understanding, just look at it at rest.


The material of the hub has good tensile and compressive strength, and each pillar can share the pressure. More simply, because the material in the hub can actually support this capability. The mechanics of materials are often beyond our expectations. For example, the load-bearing capacity of a building is far more impressive than that of a wheel carrying a ton or two of a car. The capacity of a building can be as high as 200 kilograms per square meter, and that's just concrete. But these are complex questions about the mechanics of materials, and I don't have enough space to go into them, but I hope you can get a sense of how amazingly tough these little pillars of the wheel hub are.


And the bearing capacity of each wheel hub is at least six or seven hundred kilograms, for the BMW X5, such as more than two tons of car natural its wheel hub material and structure is more powerful, so small wheel hub bear big car is a piece of cake.
