The front axle shaft is an important component in the automotive transmission system, mainly used to transmit power from the differential to the front wheels and drive the vehicle.

Power transmission: The front half axle connects the differential and front wheels, transmitting the engine's power to the driving wheels to achieve forward or backward movement of the vehicle.

Steering support: In front wheel drive (FF) or four-wheel drive (4WD/AWD) models, the front half axle also needs to be coordinated with the steering system to ensure flexible steering of the vehicle.
