The invention relates to a steering column (1) for a motor vehicle. The steering column has a steering column body (10) for supporting a rotatable steering shaft (12); a sleeve (14), which is arrangedlongitudinally movably in an opening (10a) of the steering column body (10); a collision tube (16), which is arranged longitudinally movably in an opening (14a) of the sleeve (14); a drive (56) for adjusting the steering column (1); and an energy absorption mechanism (17), which is used for absorbing axial impact energy and comprises an energy absorption element (20) and a collision stroke limiting element (22); wherein the energy absorbing element (20) is fastened to the sleeve (14) at a first longitudinal axial end section (20a) and to a spindle nut (53) of a spindle drive (52) at a secondlongitudinal axial end section (20b), and the collision stroke limiting element (22) is designed to change the collision stroke (C) of the sleeve depending on the position of the sleeve (14) in the steering column body (10).

    本发明涉及一种用于机动车的转向柱(1),其具有用于支承可旋转的转向轴(12)的转向柱本体(10)、可纵向移动地布置在转向柱本体(10)的开口(10a)中的套管(14)、可纵向移动地布置在套管(14)的开口(14a)中的碰撞管(16)、用于调节转向柱(1)的驱动器(56);和用于吸收轴向碰撞能量的、具有能量吸收元件(20)和碰撞行程限制元件(22)的能量吸收机构(17),其中,能量吸收元件(20)在第一纵轴向端部区段(20a)处固定在套管(14)上并且在第二纵轴向端部区段(20b)处固定在主轴传动装置(52)的主轴螺母(53)上,并且其中,碰撞行程限制元件(22)构造用于根据套管(14)在转向柱本体(10)中的位置改变套管的碰撞行程(C)。
