The present disclosure relates to a steering angle module comprising: a housing; the steering system comprises a steering output shaft, the steering output shaft is located in the shell, and the central axis of the steering output shaft coincides with the axis of the main pin; the double-wishbone suspension comprises an upper wishbone, a lower wishbone, a cross universal joint assembly and a ball pin assembly, in the vertical direction, the shell and the steering system are located between the upper wishbone and the lower wishbone, one of the upper wishbone and the lower wishbone is in swing connection with the output end face of the steering output shaft through the cross universal joint assembly and is perpendicular to the axis of a main pin, and the other of the upper wishbone and the lower wishbone is in swing connection with the output end face of the steering output shaft through the ball pin assembly. And the other one of the upper cross arm and the lower cross arm is rotationally connected with the shell around the axis of the main pin through a ball pin assembly. By means of the cross universal joint assembly, the steering output shaft can transmit steering torque to the double-wishbone suspension, the double-wishbone suspension can freely swing in the two directions perpendicular to the axis of the main pin relative to the steering output shaft, the damping effect of the double-wishbone suspension is improved, and stress deformation of the double-wishbone suspension is reduced.
本公开涉及一种转向角模块,包括:壳体;转向系统,包括转向输出轴,转向输出轴位于壳体内,转向输出轴的中心轴线与主销轴线重合;以及双横臂悬架,包括上横臂、下横臂、十字万向节组件和球头销组件,在垂向上,壳体和转向系统位于上横臂和下横臂之间,其中,上横臂和下横臂的其中之一通过十字万向节组件与转向输出轴的输出端面实现垂直于主销轴线的摆动连接,上横臂和下横臂的另一个通过球头销组件与壳体实现绕主销轴线的转动连接。通过十字万向节组件,可使转向输出轴的向双横臂悬架传递转向力矩,又可以使双横臂悬架相对于转向输出轴实现垂直于主销轴线两个方向的自由摆动,提高了双横臂悬架的减震效果以及减小了双横臂悬架的应力变形。
