The invention discloses an automobile steering column adjusting and locking mechanism capable of preventing tooth abutting. The automobile steering column adjusting and locking mechanism comprises a pin shaft and an adjusting cam pair arranged on the pin shaft in a penetrating mode. The automobile steering column adjusting and locking mechanism further comprises an axial toothed plate which is fixed on the upper tubular column body and radial toothed plate which is fixed on the mounting bracket; the mounting bracket is fixed with a frame; the automobile steering column adjusting and locking mechanism also comprises an axial tooth block which is locked with the axial tooth plate in a matched mode, the axial tooth block can move relative to the pin shaft in the extension direction of the pin shaft, and the axial tooth block is pressed towards the axial tooth plate through an elastic component I; and the automobile steering column adjusting and locking mechanism also comprises a radial tooth block which is matched and locked with the radial tooth plate, can move relative to the pin shaft in the extension direction of the pin shaft, and is pressed towards the radial tooth plate through an elastic component II. According to the adjusting and locking mechanism, the influence on the adjusting and locking mechanism when the tooth plate and the tooth block abut against the teeth can be effectively eliminated, so that the overall structure height of the adjusting and locking mechanism is not changed, the adjusting cam pair can still rotate in place to complete clamping, and the axial and radial locking function of the steering column is achieved.
本发明公开了一种防顶齿的汽车转向柱调节锁紧机构,包括销轴以及穿于销轴上的调节凸轮对;还包括固定在上管柱体上的轴向齿板以及固定在安装支架上的径向齿板;所述安装支架与车架固定;还包括与轴向齿板配合锁紧的轴向齿块,所述轴向齿块可沿销轴延伸方向与销轴相对运动,并通过弹性部件I将轴向齿块压向轴向齿板;还包括与径向齿板配合锁紧的径向齿块,所述径向齿块可沿销轴延伸方向与销轴相对运动,并通过弹性部件II将径向齿块压向径向齿板。本调节锁紧机构能够有效消除齿板与齿块发生顶齿时对调节锁紧机构的影响,使得其整体结构高度不发生变化,从而让调节凸轮对依然能够旋转到位完成夹紧,从而实现对转向柱轴向和径向的锁紧功能。
