Semi-trailer axle shaft Failure Analysis
Of fracture, composition and microstructure were detected, analysis of semi-trailer axle shaft in the assembly, calibration appear in breakage. The results show that the axle shaft there is loose material, such as internal shrinkage and residual defects and metallurgical processing of hot forging and heat through burning adverse widmanstatten, the combined effect of these factors resulted in lower toughness, occurred in forging internal split, eventually resulting in the shaft when the brittle fracture by external forces.
Axle semi-trailer semi-trailer is an important component in service is not allowed to use fracture. A company's semi-trailer axle shaft system using car 35 made of quenched and tempered steel. Its production processes are: forging (forging) quenching → forming → forging heat tempering → coarse, fine-turning high-frequency quenching → file → bearing box girder with welded axle assembly → → calibration finished. One axle shaft forgings Department Subcontractor supply. However, a batch production of the shaft in the assembly, calibration have appeared in more than (5) shaft breakage, which in the past, mass production has never happened before, and seriously affected the production of semi-trailer axle, but also using the same batch of parts of the semi-trailer driving the car, a security risk. To identify the cause of these broken shaft, to ensure product quality, this analysis.
