At present, most of the suspension devices of special vehicles adopt a torsion shaft suspension system. The torsion shaft is an important part in a suspension device of the crawler-type vehicle, and when the vehicle runs on an uneven road surface, the torsion shaft can achieve the purposes of buffering and shock absorption through elastic torsion and energy release. In the working process, the torsion shaft is often subjected to the action of large stress, large strain, impact and alternating torque load, so that fatigue fracture is easy to occur from the tooth root, and the bottleneck limiting the overall performance of the vehicle is formed. Therefore, it is important to improve the working performance and fatigue life of the torsion shaft. The surface processing and strengthening process methods are various, and a rolling processing method is mostly adopted in the actual production of the torsion shaft to improve the fatigue resistance, the processing precision and the use performance of the torsion shaft.
