Axle Application

The axle is a key component in the vehicle's drivetrain, located between the final drive and the drive wheels. It transmits the engine's torque to the wheels while also bearing the vehicle's weight. Typically a solid cylindrical structure, the axle is internally connected to the differential via gears or universal joints and externally to the wheel hubs. Acting as a "power bridge" between the differential and the wheels, the axle combines transmission, load-bearing, and steering functions. Depending on the vehicle's layout and suspension configuration, axles can be categorized as front/rear, drive/steering, and integral/split. Understanding the structure and working principles of axles facilitates proper selection, maintenance, and diagnosis of vehicle driveline problems.
