Extended data hub, English name: Car Rim, is a cylindrical metal part that takes the axle as the center to support the tire. In layman's terms, it is the part where the axle is installed in the center of the wheel, and it is an important part connecting the brake drum (brake disc), wheel disc and half axle.
The so-called "tire" is the rubber part in the wheel of a car, which is soft in itself. Therefore, the cylindrical part whose center is installed on the shaft on the inner contour of the tire is called the hub. Due to different language habits, many people call the wheel hub different, such as "rim", while many friends in the south call it "tire bell" or "car bell".
