The composition and performance of automobile wheels

The car hub includes a wheel for connecting the axle and a wheel ring for installing the tire. The center of the wheel is provided with a central hole, and the outer side of the central hole is provided with a plurality of bolt holes at equal intervals along the circumferential direction. The wheel rim is sequentially provided with Outer rims, beads and inner rims. The characteristic of the automobile wheel hub is that the ring portion and the inner rim are formed along the circumference of the ring space. The ring space is separated by side walls when forming multiple air chambers. The upper wall of each air chamber is provided with a through hole, which can be connected to the tire. In the inner space, the wheel hub of the utility model has a resonant sound-absorbing structure, has good rigidity and dimensional stability, and can obtain better wheel noise reduction performance. Automobile hub refers to the cylindrical metal part that supports the tire with the shaft as the center, that is, the part that the center of the wheel is installed on the axle. It is an important part that connects the brake drum, the wheel and the half shaft. It is usually cast or forged by steel or aluminum alloy made.

Due to the heavy-duty steel wheels, the shape is rough, although the price is low, they are rarely used, and the aluminum alloy wheels have the characteristics of light weight, good comfort, and beautiful appearance. I hope the above can help you. Tags: car hub.
