The present invention relates to an adjustment drive (6) for a steering column (1) for a motor vehicle, comprising a housing (64) that can be connected to the steering column (1), in which housing a gearwheel (7), which can be rotationally driven by a motor (63), is mounted in a bearing assembly (72, 73) so as to be rotatable about a spindle axis (S), and against which gearwheel a threaded spindle (62), which engages in a spindle nut (66), is axially supported in the direction of the spindle axis (S). In order reduce manufacturing and installation costs, according to the invention an energy absorption device (9) is arranged between the threaded spindle (62) and the housing (64), which energy absorption device is designed to absorb kinetic energy when the threaded spindle (62) moves relative to the housing (64) in the direction of the spindle axis (S).
本发明涉及一种用于机动车辆的转向柱(1)的调节驱动器(6),该调节驱动器(6)包括能够连接至转向柱(1)的壳体(64),在该壳体(64)中,能够由马达(63)在旋转方面驱动的齿轮(7)在轴承组件(72、73)中安装成能够绕主轴轴线(S)旋转,并且接合在主轴螺母(66)中的螺纹主轴(62)在主轴轴线(S)的方向上被轴向地支承抵靠该齿轮。为了降低制造和装置的成本,根据本发明,在螺纹主轴(62)与壳体(64)之间布置能量吸收装置(9),该能量吸收装置设计成在螺纹主轴(62)沿主轴轴线(S)的方向相对于壳体(64)移动时吸收动能。
