1. Driver Shaft, also called drive shaft (CVJ, CV joint, constant velocity joint), is the shaft that connects the differential with the drive wheels. 

2. The half shaft is the shaft that transmits torque between the gearbox reducer and the drive wheel, and its inner and outer ends each have a universal joint (U/JOINT) through the splines on the universal joint, the reducer gear and the hub bearing. Circle connection. 3. The half shaft is the shaft that transmits torque between the gearbox reducer and the drive wheel (mostly solid in the past, but because the rotation unbalance control of the hollow shaft is easier, so many cars use the hollow shaft), its inner and outer ends have A universal joint (U/JOINT) is respectively connected with the reducer gear and the inner ring of the hub bearing through the splines on the universal joint.
