A car wheel hub (or wheel hub assembly) is the central mounting component that connects a vehicle's wheels to the suspension and drivetrain. [1]
Main Functions of a Car Hub
* Wheel Attachment and Rotation: It provides a sturdy mounting surface for the wheel studs and wheel, allowing the wheel to spin freely and smoothly with minimal friction via integrated bearings. [1, 2, 3]
* Weight Support: It bears the heavy static weight of the vehicle as well as dynamic loads experienced during cornering, accelerating, and braking. [1, 2]
* Power and Torque Transfer: On driven wheels, the splined center of the hub mates with the axle shaft to transfer engine power directly to the tires. [1]
* Brake Integration: It houses or mounts the brake rotor or drum, ensuring exact alignment for safe and effective
