Now that the number of cars on the streets has increased, there is no doubt that this thing has occupied a very high place in our lives, and we cannot do without it now. Although some people do not know the car very well, but some basic knowledge they still understand, I don't know if you have noticed a small iron piece under the car door.
This little thing has a groove, and it will have this thing under every car, and some of the more attentive owners may observe its presence. This thing is very strange in shape and strange in location, so what is its use?
Don't underestimate this small iron sheet, its role is not smaller than the engine. As we all know, when we go to repair the car, the staff must use the tools to hoist our car up, so that they can conduct a comprehensive inspection of the car and find the root of the problem. So when hoisting the car, you need to use several fulcrums on the car, what is the use of the small iron sheet with grooves under the door? Old driver: Good use is the baby, bad use is the killer! And this small piece of iron is actually one of the fulcrums, and its role is quite large.
It is actually called the chassis support block, and we can see from the name that it plays a supporting role. The structure of the car is very complex, and because the materials used in each position of the car are different, their hardness will also vary. Some parts of the car may have stronger bearing capacity, but there are also some places with weaker bearing capacity, and when lifting the car, we use the part with stronger car bearing capacity.
Let's first look at a car skeleton diagram, from this picture we can see that the strength of each part of the car is not the same, of which purple and red are high-strength steel, so their hardness is very high. We need to use these parts when we lift the car. Let's look at the position under the door, it is purple, which means that its strength is relatively high, which is why the staff will choose to use the small groove card to lift the whole car.
I believe that everyone knows the jack thing, when the car tire is changed or the car breaks down, we all need to use it, its role is relatively large, we all need to use it to support the car. Many owners who do not know much about this aspect of the professional knowledge may put the jack on the edge of the chassis of the vehicle and then prop up the whole car, which is actually very wrong, because it is not only dangerous, but also easy to damage the car.
Because the steel used in this position is generally relatively light, if we use a jack in this place, it is easy to damage the car, and when it is serious, it will deform the car, and the damage to the car is very large.
Moreover, when selling used cars, if the car has such grooves, it will be considered that the accident car cannot be sold or can only be sold at a low price. From this point of view, the role of this small card is still very large, and it is needed in the process of repairing cars or changing tires and so on. Do you usually pay more attention to this thing?
