The invention provides a gapless adjustment electric adjustment steering column which comprises a lower tubular column and an upper tubular column sleeved with the lower tubular column, the lower tubular column is provided with at least two mounting holes distributed in the axial direction, and pin holes distributed coaxially are formed in the side walls of the two ends of each mounting hole; wherein the first elastic deformation part is arranged on the outer circumferential surface of the upper tubular column and used for eliminating a gap between the upper tubular column and the lower tubular column, and the second elastic deformation part is arranged between the first elastic deformation part and the lower tubular column and used for controlling the pressure between the first elastic deformation part and the upper tubular column. And a cylindrical pin locked in the pin hole is further included. According to the electric adjusting steering column capable of realizing gapless adjustment, the installation gap between the upper tubular column body and the lower tubular column body is eliminated, the pre-tightening pressure can be adjusted so that a steering wheel can be prevented from loosening in the normal running process of a vehicle, and the driving comfort and safety are improved.

    本发明提供一种无间隙调节的电动调节转向柱,包括下管柱和套装于所述下管柱内部的上管柱,所述下管柱设有轴向分布的至少两个安装孔,各所述安装孔的两端侧壁上开设有同轴分布的销孔;还包括设于所述上管柱外周面、用以消除所述上管柱与所述下管柱之间间隙的第一弹性变形件,以及设于所述第一弹性变形件与所述下管柱之间、用以控制所述第一弹性变形件对所述上管柱之间压力大小的第二弹性变形件;还包括锁紧于所述销孔内的圆柱销。上述无间隙调节的电动调节转向柱,消除了上管柱与下管柱之间的安装间隙,预紧压力可调节,以避免车辆正常行驶过程中方向盘松旷,提升了驾驶舒适性和安全性。
