Before introducing the half axle, let"s first understand how the power of the car is transmitted.

Automobile transmission system
The driving force generated by a car engine has to go through a series of power transmission devices to reach the driving wheels. The power transmission mechanism between the engine and the driving wheels is called the transmission system of the automobile, which is mainly composed of clutches, transmissions, transmission shafts, universal transmissions, main reduction differentials, and half shafts.

The power output by the engine first passes through the clutch, and after the torque and speed are changed by the transmission, the power is transmitted to the final drive through the transmission shaft, and finally the power is transmitted to the driving wheels through the differential and the half shaft.

Half shaft
The half shaft, that is, the constant velocity universal joint assembly, is installed between the differential or end reducer gear and the wheel, and consists of two or one set of constant velocity universal joints, intermediate shafts (core shafts) and other parts. The power of the engine is transmitted to the wheels to drive the car.

The two constant velocity universal joints (also known as ball cages) on the half shaft are divided into inner and outer parts. One end of the outer ball cage is mounted on the automobile hub bearing and is splined on the inner ring of the hub bearing to transmit power. The connection method of the inner ball cage is also through spline engagement, the bearing diameter of the inner ball cage has a support and protection function, and the power is transmitted through the spline and the gear of the reducer.
