The key of articulated truck is to connect the front and rear parts of the hinged joint, which connects the power part of the vehicle with the load part. As the connector of the front frame and the rear frame, the hinged joint plays an important role in the hinged joint. After a long time running, the hinge joint is affected by the impact, bending moment and other composite loads, and its thread will appear wear, break and other failure forms. Based on the analysis of the structure and current situation of the hinge joint, the advantages and disadvantages of the hardfacing process and the inlay process are compared, and a better scheme for repairing the thread wear of the hinge joint is proposed.
