The invention relates to a spindle drive (10) for adjusting a movable part in a motor vehicle at different adjustment speeds, and to a method for operating such a spindle drive (10), comprising a spindle (12) driven by means of an electric motor (20), said spindle having a spindle thread (14), the spindle thread has a first axial spindle region (21) and a second axial spindle region (22), the first axial spindle region (21) having a first thread pitch (31) which engages with a first spindle nut (41) of a corresponding first nut pitch (51), and the second axial spindle region (22) having a second thread pitch (32) which engages with a second spindle nut (41) of a corresponding first nut pitch (51). The first and second spindle nuts (41, 42) have a second thread pitch (52) that meshes with a second spindle nut (42) having a corresponding second nut pitch (52), the first and second spindle nuts (41, 42) being able to provide different adjustment speeds with the same rotational speed of the electric motor (20).

    本发明涉及一种主轴驱动装置(10),其用于以不同的调节速度对机动车中的可动部件进行调节,并且涉及一种用于运行这样的主轴驱动装置(10)的方法,其具有借助电动马达(20)驱动的主轴(12),所述主轴具有主轴螺纹(14),所述主轴螺纹具有第一轴向主轴区域(21)和第二轴向主轴区域(22),其中所述第一轴向主轴区域(21)具有第一螺纹螺距(31),该第一螺纹螺距与相对应的第一螺母螺距(51)的第一主轴螺母(41)啮合,并且第二轴向主轴区域(22)具有第二螺纹螺距(32),该第二螺纹螺距与具有相对应的第二螺母螺距(52)的第二主轴螺母(42)啮合,其中第一主轴螺母和第二主轴螺母(41、42)在所述电动马达(20)的转速相同的情况下能够提供不同的调节速度。
