1. Working principle of wheel hub bearing

Wheel hub motor bearings are an important part of cars, motorcycles and other vehicles. Their main function is to support the wheels and reduce the friction resistance between the wheels and the ground, helping the vehicles drive more smoothly. The working principle of wheel hub bearings involves some basic concepts of mechanics, including rolling friction, sliding friction, torque transmission, etc.

Hub bearings include inner rings, outer rings, rolling elements and cages. The rolling elements generally use steel balls or rollers, and ball hub bearings are widely used in vehicles. Ball hub bearings reduce friction through rolling friction. When the wheel rotates, the inner ring, outer ring and rolling elements of the hub bearing rotate together. The rolling elements use their own round surfaces to reduce friction, allowing the wheel to rotate more freely.

In addition to rolling friction, wheel bearings also involve sliding friction. Sliding friction mainly occurs in sliding bearings, while hub bearings usually do not use sliding friction. Under abnormal circumstances, such as insufficient lubrication or failure, sliding friction will appear, which will have a great impact on the life of the wheel hub bearing.

Finally, torque transmission is also an important working principle of wheel hub bearings. When the vehicle is running, the wheels are connected to the axle through the wheel hub bearings. Since the wheels are subject to a large load, the wheel hub bearings must be able to withstand large moments. Hub bearings share the load through the inner ring, outer ring and cage, keeping the wheel stable and less prone to damage.

In short, the working principle of wheel hub bearings is to support the wheels and reduce resistance through rolling friction, sliding friction and torque transmission, which has an important impact on the safety and stability of vehicles such as automobiles.

2. The role of wheel hub bearings

Wheel bearings are one of the components that make up the chassis (suspension) of a car. It is one of the parts that can only be seen after removing the brake disc. It is called a "hub bearing" because it is the bearing used in the part called the "hub".

The function of the hub is to connect the brake disc to the wheel and make it rotate. The hub holds 4 to 5 bolts. These are called "hub bolts" because they are used in the wheel hub and install the brake rotor, wheel and spacer for custom users.

Hub bearings are used on the outside of the rotating shaft as the hub rotates. For example, third generation wheel hubs have grooved "splines" for mounting the drive shaft. There are also splines on the drive shaft side, so by combining these along the splines, the driving force generated by the drivetrain is transmitted to the wheel hub.

Finally, the driveshaft is secured to the wheel hub with a large nut called a "hub nut." This is a very important part, for example, the tightening torque of a small car is about 240 N·m.

3. Avoid wheel hub bearing problems through regular maintenance

The structure of the wheel hub bearing currently used in automobiles is that the hub shaft is mounted on the wheel hub bearing. It's easy to understand when you actually view the car, so if you plan on having your car serviced in the near future, it's best to ask for one.

Whether wheel hub bearings play their due role plays an important role in leading a safe car life. If a wheel breaks while driving, surrounding drivers and pedestrians are likely to be involved in an accident. Perform regular maintenance to check the condition, and if performance degradation is found, replace it as soon as possible.
