The invention discloses an automobile mechanical steering gear assembly which comprises a box body, a gear, a rack, a rack supporting assembly and a left pull rod assembly, a cavity penetrating in the left-right direction is formed in the box body, the rack is arranged in the cavity in the mode that the rack can slide in the left-right direction, and the gear is meshed with the rack; the left pull rod assembly is connected with the left end of the rack through a pull rod inner ball cup, the rack supporting assembly is located below the meshing position of the gear and the rack, the gear assembly further comprises a lining arranged in the cavity, a middle hole for the rack to penetrate through is formed in the middle of the lining, and the rack supporting assembly is located below the meshing position of the gear and the rack. The left end of the lining is provided with a flange protruding outwards in the radial direction. The cavity comprises a ball cup containing cavity, a lining installation cavity and a rack passing cavity which are sequentially arranged from left to right, and the ball cup containing cavity and the lining installation cavity are both located on the left side of the rack supporting assembly. The bending degree of the rack can be reduced, and box breakage caused by serious bending of the rack is prevented.

    本发明公开了一种汽车机械转向器总成,包括箱体、齿轮、齿条、齿条支撑组件以及左拉杆总成,所述箱体的内部具有沿左右方向贯通的空腔,所述齿条以能够沿左右方向滑动的方式设置在所述空腔内,所述齿轮与齿条啮合,所述左拉杆总成通过拉杆内球头座与所述齿条的左端连接,所述齿条支撑组件位于所述齿轮与所述齿条啮合处的下方,还包括设置在所述空腔内的衬套,所述衬套的中部设置有用于供齿条穿过的中孔,所述衬套的左端设置有沿径向向外凸出的翻边;所述空腔包括从左至右依次设置的球头座容纳腔、衬套安装腔以及齿条通过腔,所述球头容纳腔和衬套安装腔均位于齿条支撑组件的左方。本发明能够降低齿条的弯曲程度,防止因齿条弯曲严重导致箱体破裂。
