  • Patent number: 10808812
    Abstract: A spindle drive includes a housing, a spindle, e.g., a threaded spindle, a trapezoidal threaded spindle, a ball circulation spindle or planetary roller spindle, and a spindle nut that is operatively connected to the spindle. The spindle nut is guided on the housing in a manner that allows it to be moved back and forth in response to rotational movement of the spindle in the axial direction thereof. On at least one axial side, the spindle nut includes an annular groove or is connected, e.g., screw-connected, to a part that has an annular groove. An annular collar is formed on the housing. The collar enters or extends into the annular groove in response to the spindle nut reaching an associated or a corresponding axial position.
