摘　　要：铰接式卡车的关键在连接前后两个部分的铰接头,通过铰接头将车辆的动力部分与载物部分连接起来,作为铰卡前车架和后车架的连接器,铰接头在铰卡中起着极为重要的作用。车辆经过长时间的运行,铰接头受冲击、弯矩等复合载荷影响,其螺纹会出现磨损、断扣等失效形式。通过对铰接头结构及现状进行分析,对比堆焊工艺与镶套工艺优缺点,提出一种较优的铰接头螺纹磨损修复方案。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.
