Troubleshooting

The common damages of the axle shaft include bending, twisting, fracture, spline wear and so on. The half shaft shall be inspected by magnetic flaw detector or oil immersion percussion method. If there is any crack, it shall be replaced. The radial circular runout of the unmachined surface in the middle of the half shaft shall not be greater than 115 mm; The radial circular runout of the outer cylindrical surface of the spline shall not be greater than 0 25mm;  The circular runout of the inner end face of the axle shaft flange shall not be greater than 0 15 mm。 If the radial circular runout exceeds the limit, cold pressing correction shall be carried out; If the circular runout of the end face exceeds the limit, it can be corrected by turning the end face.

application

The half shaft is the shaft that transmits torque between the gearbox reducer and the driving wheel (mostly solid in the past, but the hollow shaft is easier to control the rotation imbalance. Therefore, many cars use hollow shafts). Its inner and outer ends have a universal joint (U / joint) respectively, which is connected with the reducer gear and the inner ring of the hub bearing through the spline on the universal joint.

The axle shaft is used to transfer power between the differential and the drive wheel. The half axle of ordinary non breaking drive axle can be divided into full floating, 3 / 4 floating and semi floating according to different support forms at the outer end.

Product knowledge

The driver shaft (CVJ, CV joint, constant velocity joint) is the shaft connecting the differential with the drive wheel. The half shaft is the shaft that transmits torque between the gearbox reducer and the driving wheel. Its inner and outer ends are respectively provided with a universal joint (U / joint), which is respectively connected with the reducer gear and the inner ring of the hub bearing through the splines on the universal joint.

matters needing attention

Take the truck as an example, if the axle oil seal is damaged, there will be oil leakage from the oil seal, and the leaked oil will be adsorbed at the position of the brake pad. The most direct harm of oil on the brake pad is brake failure. If there are problems during driving, it is more dangerous to step on the brake. In addition, the rear package will be short of oil, and there are large and small splayed wheels and planetary gears [referred to as differential] in the rear package, In case of lack of gear oil lubrication, it is very easy to cause damage to the gear in the rear package.
