The invention discloses an anti-side-rolling straight-bar square-cone torsion bar for rolling stock. The torsion bar comprises a torsion bar body, a connecting part of two ends of the torsion bar body and a rocker arm is a polyhedron obtained by cutting a quadrangular pyramid of which the center line coincides with the axis of the torsion bar and the vertex is positioned at the side far away from the torsion bar; the taper of the quadrangular pyramid is 1: 10 or 1: 16 or 1: 20, and the rocker arm is provided with a combination surface matched with the connecting part of the torsion bar body. The invention further provides a machining process of the anti-side-rolling torsion bar of rolling stock, and the machining process comprises the steps that the torsion bar body is subjected to thermal refining after rough machining, and shot blasting is conducted on the surface of the torsion bar body. According to the anti-side-rolling torsion bar for rolling stock, a face contact kinematic pair structure is adopted, the connection strength is greatly improved, higher safety coefficient is guaranteed, the assembly process is simple, and the torsion resistance and compactness are improved.

    本发明公开了本发明提供的一种机车车辆抗侧滚直杆方锥扭力杆,包括扭力杆本体,所述扭力杆本体两端与摇臂连接的连接部为用一个中线与扭力杆轴线重合且顶点位于远离扭力杆一侧的四凌锥切割后得到的一个多面体,所述四凌锥的锥度为1:10或1:16或1:20,在摇臂上设有与扭力杆本体连接部相适配的结合面。本发明还提供了上述机车车辆抗侧滚扭力杆的加工工艺,包括:所述扭力杆本体在粗加工后经过调质处理,并对其表面进行喷丸处理。本发明的机车车辆抗侧滚扭力杆采用面接触运动副结构,大大提高了连接强度,保证了更高的安全系数,且装配过程简单,提升了抗扭性能和紧凑性。
