The straight tie rod assembly without axial torsion damping usually includes a curved steering tie rod and steering ball pins arranged at both ends of the curved steering tie rod. The curved steering tie rod is a three-stage structure, with the front and rear ends being an inclined straight tube and the middle part being a curved tube. The ends of the straight tube are fixedly connected to the steering ball bowl on the steering ball pin, and at the same time, the opening directions of the two steering ball bowls point to different vertical planes.
