The automobile half shaft is also called the drive shaft, which connects the differential with the drive wheels. The semi-shaft is the shaft that transmits torque between the gearbox reducer and the drive wheel. There is a universal joint (U/JOINT) on the inner and outer ends of the shaft, which is connected to the reducer gear and the inner ring of the hub bearing through the spline on the universal joint. .
The role of automobile axle shaft
The half shaft transmits the power from the differential to the left and right driving wheels.
The half shaft is a solid shaft that transmits large torque between the differential and the drive axle. Its inner end is generally connected with the side gear of the differential by a spline, and the outer end is connected to the drive by means of a flange disc or a spline. The wheel shells of the wheels are connected.
The semi-axle structure is different due to the different structure of the drive axle. The semi-axle in the non-disconnected drive axle is a rigid full axle;
The half shafts in the steering drive axle and the split drive axle are segmented and connected by universal joints.
Automobile half shaft structure
The half shaft is used to transmit power between the differential and the drive wheels. The half shaft is the shaft that transmits the torque between the gearbox reducer and the drive wheel. Generally, it used to be mostly solid. Because the hollow shaft is easier to control unbalanced rotation, now, many cars use a hollow shaft. The U/JOINT is connected to the gear of the reducer and the inner ring of the hub bearing through the spline on the universal joint.
