ເຄື່ອງຈັກເຄິ່ງລົດຍົນກໍ່ຖືກເອີ້ນວ່າເພົາຂັບ, which connects the differential with the drive wheels. The ເພົາຂັບ is the shaft that transmits torque between the gearbox reducer and the drive wheels. There is a universal joint (U/JOINT) at 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.
ໄດ້ເພົາຂັບ 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 through a spline, and the outer end is connected to the drive through a flange or spline. The wheel shells of the wheels are connected.
