The working principle of hub bearings,

1. Hub bearings are divided into first, second and third generation hub bearings according to the structure.

2. The first generation of hub bearings is mainly composed of inner ring, outer ring, steel ball and cage. Its working principle is shown in Figure 1.

3. The working principles of the first-, second-, and third-generation wheel bearings are similar to ordinary bearings.

4. They use steel balls to roll in the inner ring, outer ring, or flange raceway, load and rotate relatively, so that the car runs.

Characteristics of hub bearing abnormal noise,

1. The hub bearing rotates with the wheel, and the abnormal noise frequency is proportional to the wheel speed. As the vehicle speed increases, the abnormal noise of the hub bearing continuously becomes stronger. Generally, the abnormal noise only occurs in a narrower speed section.

2. The abnormal noise strength of the hub bearing is proportional to the load it bears. When the car turns, the hub bearing bears a large load, and the abnormal noise is more obvious.

3. The abnormal noise of the hub bearing is easily confused with the abnormal noise of the transmission systems such as tires, engines, transmissions, transmission shafts, and universal joints.
