Wheel basic knowledge
Wheel hub: Also called rim, it refers to the part where the axle is installed in the center of the wheel. It is an important part connecting the brake drum (or brake disc), the wheel disc and the axle shaft. It is sleeved on the shaft tube or steering knuckle journal with bearings.
Classification
From the manufacturing process, there are two types: casting and forging. Generally, casting rings are made of aluminum, while forging rings are made of aluminum and titanium. In general, the forged ring is strong, and the forged ring is used for racing. The first-level forged ring used for racing is equivalent to half the weight of our ordinary cast ring. The lighter the weight, the lower the power loss of the car, and the faster you run.
Another distinguishing index of the wheel hub is the difference between the hole pitch and the eccentricity. To put it simply, the hole pitch is the position of the screw, and the eccentricity reflects the distance from the surface (fixing surface) of the hub used for screwing to the center line of the hub. The requirements for a good wheel hub are: uniform density, round shape, low thermal deformation, and high strength.
The wheels can be updated. Some people upgrade their cars and use larger wheels, but the outer diameter of the tire remains the same, the flatness of the tire becomes larger, the lateral swing of the car is smaller, and the stability is improved, but the car What is lost is comfort.
About the maintenance method of the wheel
The wheels of luxury cars are mostly made of aluminum alloy. This kind of wheel looks beautiful, but it is also very delicate. To keep the appearance of the hub beautiful, in addition to being extra careful to prevent accidental damage to the hub during driving, the hub must be maintained and maintained regularly. If you have time, you should perform a thorough cleaning once a week.
1. Wash away the sand particles attached to the surface of the wheel hub and the dirt that is easy to damage the wheel hub. Otherwise, the surface of the alloy will be corroded and damaged.
2. Treat the inner and outer surfaces of the wheel hub with an acid-proof cleaner. It is best to wax the wheel hub every 2 months to extend the life of the wheel hub.
To keep the appearance of the wheel hub beautiful, in addition to being extra careful to prevent accidental damage to the wheel hub during driving, it is also necessary to regularly maintain and maintain the wheel hub. It is recommended to wax the wheel hub once every 2 months to extend the service life of the wheel hub. But be careful not to use paint brightener or other abrasive materials on the wheel hub.
