Spindle drive for an adjustment element of a motor vehicle

A flap arrangement for a motor vehicle, comprising:

• a flap, and a spindle drive for adjusting the flap, the spindle drive comprising:
• a drive unit and a spindle-spindle nut transmission arranged downstream of the drive unit in terms of drive for generating linear drive movements, wherein the drive unit comprises a tubular drive unit housing and therein a drive motor, wherein the drive unit and the spindle-spindle nut transmission are arranged one behind the other on a geometrical spindle axis;
• and
• a spindle drive housing comprising a tubular inner housing and a tubular outer housing, wherein the tubular inner housing runs in a telescopic manner in the tubular outer housing;
• wherein the tubular outer housing of the spindle drive housing accommodates the drive unit with the drive unit housing and is connected to the drive unit;
• wherein the tubular inner housing, in a fully retracted state, overlaps with an axial overlapping portion of the drive unit;
• and
• wherein the tubular inner housing, in a fully extended state, does not overlap with the drive unit.

A spindle drive for an adjustment element of a motor vehicle, comprising:

• a drive unit, the drive unit comprising a tubular drive unit housing and a drive motor within the drive unit housing;
• a spindle-spindle nut transmission arranged downstream of the drive unit in terms of drive for generating linear drive movements, the drive unit and the spindle-spindle nut transmission arranged one behind the other on a geometrical spindle axis;
• a spindle drive housing comprising a tubular inner housing and a tubular outer housing, the tubular inner housing running in a telescopic manner in the tubular outer housing;
• and
• a first connection that is connected to the drive unit and a second connection that is connected to the spindle-spindle nut transmission, for conducting the linear drive movements apart from the spindle drive housing;
• wherein the tubular outer housing is connected to the drive unit and accommodates the drive unit with the drive unit housing;
• wherein the tubular outer housing is primarily composed of a plastic material and the drive unit housing is primarily composed of a metallic material;
• wherein the tubular inner housing, in a fully retracted state, overlaps with an axial overlapping portion of the drive unit;
• and
• wherein the tubular inner housing, in a fully extended state, does not overlap with the drive unit.
