How does a axle work?

An axle is a central shaft for rotating wheels or gears, providing support and allowing them to turn. It transmits torque from the vehicle's engine to the wheels, facilitating movement. As the wheels rotate around the axle, the axle itself remains stationary, ensuring stability and alignment. In vehicles, axles can be either fixed or drive axles, depending on whether they are connected to the powertrain or simply support the vehicle's weight.
