1.Automobile wheel bearing structure:
The largest number of wheel bearings for cars used in the past was the use of single row tapered roller or ball bearings in pairs. With the development of technology, car hub units have been widely used in cars. The range and use of hub bearing units is growing, and today it has reached the third generation: the first generation consists of double row angular contact bearings. The second generation has a flange for fixing the bearing on the outer raceway, which can be simply fixed to the axle by a nut. Make the maintenance of the car easier. The third-generation hub bearing unit is equipped with a bearing unit and an anti-lock brake system ABS. The hub unit is designed with an inner flange and an outer flange, the inner flange is bolted to the drive shaft, and the outer flange mounts the entire bearing together.

2.Automotive wheel bearing features:
The hub bearing unit is developed on the basis of standard angular contact ball bearings and tapered roller bearings. It integrates two sets of bearings and has good assembly performance, can eliminate clearance adjustment, light weight, compact structure and load capacity. Large, sealed bearings can be pre-loaded with grease, omitting external hub seals and maintenance-free. They have been widely used in cars, and there is a tendency to gradually expand applications in trucks.

If the clutch release bearing fails to meet the above requirements, it is deemed to be malfunctioning. After a failure occurs, the first thing to judge is which phenomenon belongs to the damage of the release bearing. After the engine is started, lightly step on the clutch pedal. When the free stroke is just eliminated, there will be a “rusting” or “squeaking” sound. Continue to step on the clutch pedal. If the sound disappears, it is not a release bearing problem. If there is still a sound, it is a release ring.
When checking, you can remove the clutch bottom cover, and then depress a little accelerator pedal to slightly increase the engine speed. If the noise increases, you can observe whether there is sparks. If there are sparks, it means that the clutch release bearing is damaged. If the sparks burst out one after another, it means that the release bearing ball is broken. If there is no spark, but there is a metal cracking sound, it means excessive wear.
