The connecting shaft assembly used for the tank armored vehicle has high requirements on the design index of rigidity and precision of welding structural members, and the welding technology of the parts has three difficulties. The parallelism control between first, long arm and the short arm is difficult, because two arms belong to the narrower rectangular class part of width, guarantees 0.5 mm's parallelism and needs to guarantee strictly that two arm planeness is good to end and afterbody interval are accurate. Second, because an included angle is formed between the long pull arm and the short pull arm along the circumferential direction of the step shaft, the accuracy of the included angle is difficult to control. Third, the step shaft is difficult to control the perpendicularity between the long pull arm and the short pull arm, and because the step shaft is long and is required to be inserted into the through holes at the rear ends of the two pull arms, partial constraint is formed, and the perpendicularity is not easy to realize in the axial direction in the actual operation process.
