Abstract: An off-road wide-body truck is in Inner Mongolia coal mines, as soon as it is used for a year, many cases of driving axle shell cracking and oil leakage failures appeares, and the fault form and time are highly unified. In order to solve the problem of axle shell cracking failure, the real analysis and verification model is established according to the actual working conditions investigated by following the vehicle, and the simulation analysis software is applied in combination with the working conditions characteristics of the mining area. The fault recurrence analysis is carried out on the driving axle shell cracking failure, and the root cause of the crack and oil leakage of the driving axle shell cracking is determined. Based on this, the improvement suggestion and optimization scheme are put forward for the cracking and oil leakage of the drive axle shell cracking, so that the improved axle shell can be put into the mining area for verification. After two years of use, there is no driving axle shell cracking oil leakage fault.
