Support and Force Application

Full-floating half axle: It is only responsible for transmitting torque. The support, braking, steering and other forces of the wheels are borne by the axle, making it suitable for heavy-load scenarios.
Semi-floating half shaft: It needs to bear both torque and road reaction force simultaneously. It has a compact structure but a relatively low load capacity and is suitable for light-load vehicles.
Adapt to complex road conditions
For some models (such as four-wheel drive vehicles), the half shafts need to be matched with universal joints (such as constant velocity universal joints) to maintain continuous power transmission when the wheels are bouncing up and down or turning, thereby enhancing driving stability.

Core Functions and Roles

Ultimate power transmission
The core task of the half shaft is to pass on the torque processed by the engine through the gearbox and differential to the driving wheels, driving the vehicle to move forward or backward. It is the last mechanical link in the transmission system that drives the wheels.
Withstanding combined loads
During vehicle acceleration, braking, and cornering, the half shaft not only transmits huge torsional forces but also has to bear the bending moments and impact loads caused by uneven road surfaces and body roll. Especially for heavy-duty vehicles, the strength and toughness of the half shaft directly determine its survival ability under harsh conditions.
