In a fully floating axle, the axle shaft is supported by bearings inside the axle housing. The wheels are mounted on hubs that are attached to the axle shaft. When the vehicle is in motion, the axle shaft rotates and the wheels turn. However, if the vehicle hits a bump or pothole, the axle shaft can move up and down without causing the wheels to move. This is because the wheels are not directly connected to the axle shaft.
The main advantages of a fully floating axle are:
* Reduced wear and tear on suspension and drivetrain components. Because the axle shaft can move up and down independently of the wheels, it helps to reduce the stress on the suspension and drivetrain components. This is especially important for heavy vehicles that are constantly subjected to rough road conditions.
* Improved stability and handling. A fully floating axle helps to improve stability and handling by reducing the amount of unsprung weight in the vehicle. Unsprung weight is the weight of the suspension and drivetrain components that are not supported by the springs. When a vehicle hits a bump or pothole, the unsprung weight can cause the vehicle to bounce or lose traction. A fully floating axle helps to minimize this effect by reducing the amount of unsprung weight.
* Increased durability. Fully floating axles are more durable than other types of axles because they are not subjected to the same amount of stress. This makes them ideal for heavy vehicles that are used in demanding conditions.
Overall, a fully floating axle is a good choice for heavy commercial vehicles because it provides several advantages over other types of axles. These advantages include reduced wear and tear on suspension and drivetrain components, improved stability and handling, and increased durability.
