The invention relates to a spindle drive (1), comprising a spindle drive (2) having a spindle (3) and a spindle nut (4) which engages with the spindle (3), the spindle nut (4) being rotatably mounted relative to the spindle (3), the spindle nut (4) being drivably coupled to a sensor device (5), wherein the sensor device (5) comprises at least two incremental angle sensors (6) which have different speed-up and/or speed-down ratios with respect to the spindle nut (4), from which electrical signals are generated which represent the difference in angular speed of the two angle sensors (6) with respect to each other, the electrical signal is used to determine an electrical signal representing an absolute angular position of the screw (3) in a control unit (7) of the screw drive (1).

    本发明涉及一种螺杆传动装置(1),所述螺杆传动装置包括螺杆传动机构(2),所述螺杆传动机构具有螺杆(3)和与螺杆(3)接合的螺杆螺母(4),其中螺杆螺母(4)相对于螺杆(3)可旋转地支承,其中螺杆螺母(4)与传感器设备(5)可传动地耦联,其中传感器设备(5)包括至少两个增量式角度传感器(6),所述角度传感器具有相对于螺杆螺母(4)的不同的增速比和/或减速比,从中产生表示两个角度传感器(6)相对于彼此的角速度差的电信号,所述电信号用于在螺杆传动装置(1)的控制单元(7)中确定表示螺杆(3)的绝对角度位置的电信号。
