Wheels on the market can be divided into steel wheels and alloy wheels according to their materials, both of which have their own advantages and disadvantages.
I. Development history of the hub
In the past, the hub bearings of automobiles were mostly paired with single row tapered rollers or ball bearings. With the development of science and technology, automobile hub units have been widely used in automobiles. The application scope and quantity of hub bearing unit are increasing day by day, and it has developed to the third generation.
Second, the use and installation of hub bearings should pay attention to the following matters:
1. In order to ensure the safety and reliability to the greatest extent, it is recommended that you always check the wheel hub bearing regardless of the age of the vehicle-pay attention to whether the bearing has early warning signals of wear, including whether there is friction noise during rotation or whether the suspension combined wheel slows down abnormally during steering.
2. If you hear the noise from the hub bearing, first of all, it is important to find the location where the noise occurs. There are many moving parts that may produce noise, or some rotating parts may come into contact with non-rotating parts. If noise is confirmed in the bearing, the bearing may be damaged and needs to be replaced.
