What are the functions of Axle Shafts in a vehicle?

The role of the Axle shaft in the vehicle mainly includes the following aspects‌:

‌Transmitting power‌: The Axle shaft is a shaft that transmits power between the main reducer (differential) and the drive wheel. The inner end is connected to the half-Axle shaft gear of the differential, and the outer end is connected to the drive wheel hub to ensure that the power is transmitted from the engine to the wheel‌.

‌Bearing load‌: The Axle shaft is connected to the frame (or load-bearing body) through the suspension, bears the load of the car, and maintains the normal driving of the car on the road‌.

‌Adapting to different suspension structures‌: According to the different suspension structures, the Axle shaft is divided into two types: integral and disconnected. The integral Axle shaft is used with a non-independent suspension through a solid or hollow rigid beam, while the disconnected Axle shaft is a movable joint structure, which is used with an independent suspension to adapt to different vehicle needs‌.

‌Improving vehicle stability and durability‌: The Axle shaft ensures the stability and durability of the vehicle during driving by bearing and dispersing various forces from the frame and wheels, including bending moment and torque, and is the basis for vehicle driving safety‌.

‌Installation of mechanical devices‌: Mechanical devices such as gears and chains are usually installed on the Axle shaft to change the speed and direction, thereby improving the operating efficiency of the vehicle or machine‌.

In summary, the Axle shaft plays a vital role in the vehicle, not only transmitting power, but also bearing loads, adapting to different suspension structures, and improving the stability and durability of the vehicle.
