Spindle drive for moving component, particularly for component tilted around axis of rotation, comprises spindle nut coupled and uncoupled with transmitting element by coupling unit, where axial position of nut is detected by sensor

摘要

The drive comprises a spindle nut (2) coupled and uncoupled with a transmitting element (9) by a coupling unit. The axial position of the spindle nut on a threaded spindle (1) is detected by a nut position sensor. The axial position of the transmitting element on the spindle axis (10) is detected by the component sensor. The signals of the nut position sensor and the component sensor of a control unit (15) are transmitted. The spindle nut is coupled with the transmitting element when a plausibility of the signals of nut position sensor and component sensor is present.
