The invention relates to an adjustment drive (5) for a motor-adjustable steering column (1) of a motor vehicle, comprising a spindle unit (6), which has a spindle shaft (62), which engages in a spindle nut (61) and has a spindle axis (S), and a drive unit (7), which has a drive wheel (81), which can be driven by an electric motor (71) for rotation about a drive axis (A), the drive wheel is designed as a belt pulley, and a transmission wheel (82), which is drivingly coupled to the drive wheel (81) via a circulating belt (83), is connected to the spindle nut (61) or the spindle (62). In order to be able to achieve improved operating characteristics, the invention proposes that a pre-tensioning device is arranged between the drive unit (7) and the spindle unit (6).

    本发明涉及一种用于机动车的能够马达调节的转向柱(1)的调节驱动装置(5),包括主轴单元(6)和驱动单元(7),所述主轴单元具有接合到主轴螺母(61)中的具有主轴轴线(S)的丝杠(62),所述驱动单元具有能够由电动马达(71)驱动以围绕驱动轴线(A)转动的驱动轮(81),所述驱动轮构造为皮带轮,其中,与驱动轮(81)经由环绕的皮带(83)以驱动的方式联接的传动轮(82)与主轴螺母(61)或丝杠(62)连接。为了能够实现改进的运行特性,本发明提出,在驱动单元(7)和主轴单元(6)之间布置有预张紧装置。
