The invention discloses a shot peening strengthened automobile steering torsion bar which comprises a torsion bar body, the two ends of the torsion bar body are pressed and embedded into an inner hole of an input shaft/output shaft through an involute spline and a tooth top diameter in an interference fit mode to be connected, the middle portion of the torsion bar body is arranged to be a torsion rigidity section, and shot peening medium treatment is additionally arranged on the surface of the torsion rigidity section. The method has the advantages that the surface is subjected to shot peening strengthening treatment, the anti-fatigue performance is improved, the torsional rigidity is achieved, torque signals can be monitored through the sensor according to the torsion bar deformation, meanwhile, the durability characteristic is enhanced, and the automobile steering hand feeling and the system stability are optimized.

    本发明公开了一种喷丸强化的汽车转向扭杆,包括扭杆主体,扭杆主体的两端通过渐开线花键,齿顶径过赢配合压入嵌入输入轴/输出轴内孔连接,扭杆主体的中间部设置为扭转刚度区段,扭转刚度区段的表面增设喷丸介质处理。本发明具有表面喷丸强化处理,提升其抗疲劳性能,实现扭转刚度,根据扭杆变形量,传感器可以监测扭矩信号,同时增强耐久特性,优化汽车转向手感与系统稳定性的优点。
