The invention discloses a gear and rack gap adjusting mechanism which comprises a shell and a gear and rack combination, the shell is provided with a rack hole and a gear hole, a rack shaft is installed in the rack hole, a gear shaft is installed in the gear hole, the rack shaft extends into the shell to be meshed with the gear shaft, and the gear and rack gap adjusting mechanism comprises an adjusting component and a shaft sleeve. The shaft sleeve is installed in the rack hole, the rack shaft extends into the shaft sleeve, the adjusting component extends into the shell to be connected with the shaft sleeve, and when the adjusting component rotates, the shaft sleeve moves in the axial direction of the adjusting component. The adjusting component drives the shaft sleeve to move, the rack shaft is driven by the shaft sleeve to change the position of the rack shaft, and therefore the gap between the rack shaft and the gear shaft is adjusted, the structure is simple, the requirements for part machining precision and assembly precision are low, the phenomenon of abnormal sound can be reduced, and the comfort of a driver is improved.

    本发明公开了齿轮齿条间隙调整机构,包括壳体和齿轮齿条组合,所述壳体开有齿条孔和齿轮孔,所述齿条轴安装于齿条孔,所述齿轮轴安装于所述齿轮孔,所述齿条轴伸入所述壳体与所述齿轮轴啮合,包括调节构件和轴套,所述轴套安装于所述齿条孔,所述齿条轴伸入所述轴套,所述调节构件伸入壳体与所述轴套连接,当调节构件旋转时,所述轴套沿调节构件的轴向方向移动。通过调节构件带动轴套进行移动,使齿条轴在轴套的带动下改变齿条轴的位置,从而调整齿条轴和齿轮轴之间的间隙,结构简单,对零部件加工精度和装配精度要求低,能够减少出现异响的现象,提升驾驶员的舒适感。
