Abstract：

To lighten the weight of transmission shaft for special heavy truck without weakening its power, the main components were redesigned, and the forging process and machining process of component blanks were replanned. Then, the universal joint assembly was designed, and its dimension was determined. Therefore, the axle tube size was determined as Φ150 mm×7 mm by calculation, and the spline shaft was reselected by comparing relative performance indexes. Furthermore, the forging process of end face tooth flange fork and spline shaft blanks and the machining process of spline shaft were improved, and the lightweight design and manufacture of transmission shaft assembly for special heavy truck were realized. The practical results show that the material utilization rate is improved by reducing the feeding size of key parts without reducing the performance of transmission shaft. So the lightweight design and manufacture of transmission shaft assembly for special heavy truck are realized with a 6.76 kg weight loss of transmission shaft assembly, namely the weight loss rate is 8.45%.
