[0002] Axle shafts, also known as drive shafts, are important components that connect the differential and the drive wheels. Their main function is to transmit torque. When the vehicle is driving, the power output by the engine is transmitted to the differential through the gearbox reducer, and then transmitted to the drive wheels through the axle shafts by the differential to drive the vehicle forward or backward.

[0003] At present, during the processing of automobile half-axles, cracks may appear on the outer surface of the half-axles due to the influence of materials, manufacturing processes, design and other issues. Therefore, the half-axles during processing must be inspected to eliminate safety hazards.
