Main Functions and Roles

Transfer driving force
The half shaft directly transmits the power from the transmission and differential to the wheels, enabling the vehicle to move forward and backward.

Compensation suspension motion
During the vehicle's operation, the suspension system moves up and down. The half shaft compensates for the movement of the wheels and the change in steering through a constant velocity universal Joint (CV Joint) or a sliding structure to ensure the continuity and stability of power transmission.

Support steering
Especially for front-wheel drive models, the half axle not only transmits power but also needs to withstand changes in steering angles, and thus requires strong flexibility and durability.

Maintain smooth transmission
High-quality half shafts can reduce vibration and noise, and enhance the overall handling performance and driving comfort of the vehicle.
