Measuring unit for drive device for propelling movable element, particularly door, flap, cover, or motor vehicle, has spindle and spindle nut, which are movable relative to each other along drive direction
摘要
<p>The measuring unit has a spindle (2) and a spindle nut (3), which are movable relative to each other along a drive direction (A). The relative position of the spindle and the spindle nut is determined using the measuring unit. The measuring unit has a capacitor, whose capacitance is changed depending on the position of the spindle and the spindle nut. The spindle and the spindle nut are surrounded by an outer tubing element (4), which defines the capacitor surface of the capacitor.</p>
