Wheel Hub for BMW

Wheel supporting: Installed on a vehicle wheel, a hub can support and bear the weight of the wheel and load transmitted from the road surface. It provides stable axle support through internal and external bearings, and allows the wheel to rotate smoothly.

Power transmission: A hub serves as the connection point between a wheel and the vehicle's transmission system. It transmits the power generated by the engine or electric motor to the wheel, thus driving the vehicle.

Suspension support: A hub works in conjunction with the vehicle's suspension system to provide suspension support for the vehicle. By alleviating vibration and impact resulting from uneven road surfaces, it leads to better riding comfort and stability.

Monitoring and control: Some hub have also integrated sensors, such as wheel speed sensor and bearing temperature sensor. These sensors are capable of monitoring real-time wheel status such as speed and temperature, and sending the information to the vehicle's electronic control system to enable operation and control of relevant functions such as ABS (antilock braking system) and traction control.

Sealing protection: A hub is equipped with sealing rings and other internal sealing components, which can effectively keep dust, moisture, and other impurities from entering the bearing components, and maintain good lubrication and operation status. This contributes to a longer service life of the hub unit and lower maintenance workload.

Wheel hub serves multiple purposes for a vehicle, including supporting, power transmission, suspension support, monitoring and control, and sealing protection. It is therefore a crucial part for vehicle performance, safety, and comfort.
