Axle

An axle is a central shaft or rod on which a wheel or a pair of wheels rotates. It serves as the main rotating component, providing a point of connection between the wheels and the vehicle's chassis, enabling movement. Axles are critical for transferring rotational motion and supporting the vehicle's weight. They can be solid, used to drive a pair of wheels, or split, allowing independent suspension. The design of an axle is dependent on the vehicle's function, weight, and the drivetrain setup. Careful design and maintenance of axles are crucial for safe and efficient vehicle operation.
