The wheel hub refers to the ring-shaped metal device outside the tire, which is installed on the axle of the car and enables the tire of the vehicle to rotate through bearings and other components. The wheel hub plays an important role in the car.
1. Support and carry the weight of the vehicle
The wheel hub is an important component of the vehicle to bear gravity. During driving, the weight of the vehicle is transferred to the wheel hub through the tire, and the wheel hub disperses the gravity to various parts of the wheel to ensure the stable driving of the vehicle.
2. Maintain vehicle balance and stability
The balance and stability of the wheel hub are very important for the driving of the vehicle. The bearing and assembly accuracy of the wheel hub determine whether the rotation of the wheel hub is smooth. If the wheel hub is unbalanced, it will cause vibration and vibration when the wheel rotates.
3. Transmit driving force and torque
The wheel hub converts the power and torque output of the engine into the driving force of the vehicle through the friction between the tire and the ground. The power transmission and driving effect of the vehicle depend to a large extent on the performance of the wheel hub.
4. Improve the appearance and wind resistance performance of the vehicle
The wheel hub is an important part of the vehicle's appearance design. Different wheel hub styles and materials can bring different appearance effects to the vehicle. In addition, a properly designed wheel hub can reduce the wind resistance of the vehicle, improve the aerodynamic performance of the vehicle, and improve the stability and fuel efficiency of the vehicle.
5. Heat dissipation and lowering brake temperature
When driving at high speed, the wheels and brakes will generate a lot of heat due to friction. The heat dissipation performance of the wheel hub can help the vehicle effectively reduce the brake temperature.
