It is very simple, the load-bearing of the car wheel is borne by all the pillars at any time, the difference is the direction of the force, some bear the tension, some bear the pressure. And alternating as the hub runs, the force spread across each post isn’t huge.
1. A conventional car has a weight of less than two tons, and four tires touch the ground. How can the body not rub against the tires? It is the four springs of the shock absorber that support the weight of the body.
1. The front suspension is all McPherson suspension, the upper part has a three-wishbone arm, the lower part is a triangular arm, there is a shock absorber assembly in the middle, and then a tie rod is connected to the steering wheel, and a drive shaft comes out of the gearbox to drive the tires.
2. Part of the rear suspension is a non-independent suspension, and a part is an independent suspension. The non-independent suspension is a steel tube hanging with the shock absorber assembly, and the shock absorber assembly is hung with the tire. Independent suspension is just a few “chopsticks” hanging on the tires, and there are shock absorber assemblies on them to support the body.
2. To put it bluntly, the four tires are connected to the tires by several “chopsticks”. Although the steel bars are very thin, they are strong enough.
The original words of the owner of Geely Automobile: “What is a car, isn’t it just a sofa on top of four reels.” When he built the car back then, his understanding was that simple, and then as you can see now, the car is as simple as a few connecting rods. We can go wherever we want to sit on the sofa, how convenient.
The automobile industry is so advanced now, so don’t think about the common sense that a few connecting rods support the car and can’t stand it. Make more money and buy a good car. There’s nothing to be afraid of filming the chassis with a camera, and automotive engineers put a lot of effort into studying its safety. It’s just that people we don’t understand are worrying about nothing!
Third, from the point of view of mechanics
Although these rods are a little thin, they are combined into a set of car fulcrum system through reasonable structural design, so that each tire screw is subjected to tension instead of bending moment or torque, avoiding stress concentration, so there will be no great stress. , is safe under normal conditions
To sum up, it is as simple as that: the tire screws are pulled four or two thousand pounds to support the car.
