What is an axle in a vehicle?

An axle is fundamentally a rod or spindle that connects the wheels of a vehicle, serving as a pivotal component in the vehicle's overall structure and operation. It allows the wheels to rotate and helps to support the weight of the vehicle while ensuring stability during movement. In essence, the axle functions as a crucial link between the left and right wheels, enabling synchronized movement and proper handling.

Understanding the axle's role is important for anyone studying commercial driving, as it directly affects vehicle performance, including steering and braking capabilities. Furthermore, knowing the function of the axle aids in better awareness of vehicle maintenance and potential issues that can arise if the axle becomes damaged or misaligned.
