The invention relates to the field of automobile steering systems, in particular to a worm and gear clearance compensation structure and an automobile steering system.The worm and gear clearance compensation structure comprises a shell internally provided with a worm, one end of the worm is fixedly sleeved with an aligning assembly, a limiting groove is formed in the shell, and the aligning assembly is arranged in the limiting groove; the center adjusting assembly can slide in the limiting groove in the direction perpendicular to the axial direction of the worm, a screw hole communicated with the limiting groove is formed in the side wall of the shell, the extending direction of the screw hole is perpendicular to the axial direction of the worm, an elastic mechanism is installed in the screw hole, and the center adjusting assembly can slide in the limiting groove in the direction perpendicular to the axial direction of the worm. The elastic mechanism abuts against the outer wall of the aligning assembly and is used for applying acting force to the aligning assembly. The invention has the beneficial effects that the clearance between the worm gear and the worm is accurately adjusted, and the steering hand feeling is optimized; the inner ring of the bearing is always parallel to the axis of the worm, so that the steering smoothness is improved; the elastic mechanism is convenient to install and replace.

    本发明涉及汽车转向系统领域,尤其涉及一种蜗轮蜗杆间隙补偿结构以及汽车转向系统,包括内部安装有蜗杆的壳体,所述蜗杆的一端上固定套设有调心组件,所述壳体内设有限位槽,所述调心组件设在所述限位槽内,所述调心组件可沿垂直于所述蜗杆的轴向方向在所述限位槽内滑动,所述壳体的侧壁上设有与所述限位槽连通的螺孔,所述螺孔的延伸方向垂直于所述蜗杆的轴向方向,所述螺孔内安装有弹性机构,所述弹性机构与所述调心组件的外壁抵接用于对所述调心组件施加作用力。本发明的有益效果是:精准调节蜗轮蜗杆间的游隙大小,优化转向手感;轴承内圈始终与蜗杆轴线平行,提升转向平顺度;弹性机构安装方便,方便更换。
