Abstract: The invention relates to a spindle drive for a closure element of a motor vehicle, which spindle drive has a spindle/spindle nut mechanism which has a spindle and a spindle nut, wherein a motor-side drive portion has a drive unit with a drive motor and the spindle, wherein the spindle is connected downstream of the drive motor, wherein a spindle-nut-side drive portion of the spindle drive has the spindle nut, wherein the spindle drive has a drive housing with at least one housing tube which is fixed axially with respect to the motor-side drive portion, wherein a guide tube is arranged radially within the housing tube, which guide tube is fixed axially with respect to the motor-side drive portion and axially guides a drive component of the spindle drive during the drive movements.

Abstract: A spindle drive for a closure element of a vehicle is provided, wherein the spindle drive has a spindle/spindle nut mechanism, which has a spindle and a spindle nut meshing therewith for generating linear drive movements along a geometric spindle axis between a spindle-side drive connection and a spindle nut-side drive connection for channeling the drive movements, wherein the spindle is axially movably guided in a spindle guide tube which is axially fixedly connected to the spindle nut for conjoint rotation and which is axially fixedly coupled to the spindle nut-side drive connection. It is proposed that the spindle nut is axially inserted over its entire length into a portion of the spindle guide tube that is formed in such a way as to be in form-fitting engagement with the spindle nut in both directions along the geometric spindle axis and in the circumferential direction around the geometric spindle axis.
