[0002] A wheel hub is a cylindrical metal part that supports the tire inside the tire contour and is centered on the shaft. It is also called a rim, steel rim, wheel, or tire bell. There are many types of wheel hubs according to different diameters, widths, forming methods, and materials. In the past, most of the wheel hub bearings of cars were used in pairs of single-row tapered roller or ball bearings. With the development of technology, car wheel hub units have been widely used in cars. The scope of use and the amount of use of wheel hub bearing units are increasing day by day, and it has developed to the third generation: the first generation is composed of double-row angular contact bearings, and the second generation has a flange for fixing the bearing on the outer raceway, which can simply put the bearing on the wheel shaft and fix it with a nut, making the maintenance of the car easier. The third-generation wheel hub bearing unit is a combination of a bearing unit and an anti-lock braking system. The wheel hub unit is designed with an inner flange and an outer flange. The inner flange is fixed on the drive shaft with bolts, and the outer flange installs the whole bearing together.
