What is the keel of the car? Where is the keel on the car

Car keel:Also known as rims, wheels, and tire bells, they are barrel-shaped metal parts that support the tire with the inner rim of the tire and are installed on the shaft in the center. There are many types of hubs according to diameter, width, molding method, and material.

The wheel hub of the ordinary model is less considered in appearance, good heat dissipation is a basic requirement, and the process is basically treated with baking paint, that is, sprayed first and then baked, the cost is more economical and the color is beautiful, and the maintenance time is long, even if the vehicle is scrapped, the color of the wheel is still unchanged.

What is a car keel? It is a barrel-shaped metal part with the inner rim of the tire supporting the tire and is centered on the shaft. According to the characteristics and needs of different models, the surface treatment process of the wheel hub will also take different ways, which can be roughly divided into two types: baking paint and electroplating.

The keel is the hub (that is, the spoke), the hub is the part that connects the rim and the axle, and if the keel does not move, the wheel cannot move!

The keel is the inner steel rim of the wheel, and there are also white alloys.

The keel is equivalent to the spine of the car, and the longitudinal protruding girder at the bottom of the car. It is the basis of the skeleton of the car.

Generally, it refers to the beam that is raised in the middle.

Then we should divide the car into "load-bearing body" and "non-load-bearing body"!

The "keel" of the "non-load-bearing body" is an independent trapezoidal chassis girder, which is mostly seen in hard-core off-road vehicles, truck-duty buses, etc

<>load-bearing body" structure, the entire body frame is an integral "keel"; It is mostly seen in sedans, urban multi-purpose SUVs, MPVs, etc

In addition to the pressure fence and the sill pile, the body is made of wooden planks as a groove, two zhang long, ranging from 4 inches to 7 inches wide, about one foot high, and a street slab is erected in the groove, which is the same as the width of the groove, one foot shorter than each end of the groove plate, and is used to place large and small axles. Up and down the pavement slabs, the whole circumference is connected by a section of keel slab leaves with wooden pins, much like the skeleton of a dragon, so it is called a keel car. Because of the use of manpower, the amount of water it draws is not large enough, but it can be used wherever the water is located, and it can be stepped on or shaken by two people, or only one person can step on or shake, which is very convenient and popular with people, and is a widely used agricultural irrigation machinery.

Keel car, that is, overturned, is a mechanical water lifting tool created by the Han Han working people. It was first recorded in the "Book of the Later Han Dynasty: The Biography of Zhang Rang": When the Han Dynasty presented the emperor, Bi Lan "overturned, thirsty for Wu, applied to the west of the bridge, and sprinkled the northern and southern suburbs of the road". Most of them think that it is the improvement of Ma Jun of the Three Kingdoms.

The keel of the car is on the axle. The car keel, also known as rims, wheels, and tire bells, is the metal part of the tire that supports the tire on the inner contour of the tire.

Car keel type:

Steel wheels: The manufacturing process of steel wheels is simple, and the casting process is mostly used. The cost is relatively low, and the resistance to metal fatigue is strong, but the inertia resistance is large, the heat dissipation is general, and it is easy to rust.

Alloy wheels: Alloy wheels are lighter in weight, less resistance to inertia, and more accurate in manufacturing. When rotating at high speed, the alloy wheel deformation is small, which is conducive to improving the straight-line driving ability and reducing fuel consumption.

The heat dissipation of Hexiao Yula gold wheels is about three times that of steel wheels, which has a certain effect on improving the braking ability of the car. Alloy wheels are made of chrome, titanium and other materials, and the manufacturing cost is high.

How to deal with car keel scratches:

Check the difference in the tread depth of the tire relative to the damaged tire and the spare tire; If the difference in the depth of the pattern is less than 1cm, the spare tire needs to be replaced; The front and rear wheels are reversed. Millions of car purchase subsidies.
