Abstract
A suspension strut for a vehicle has an air spring unit and a damper unit. The damper unit has a damper tube, which extends into a rolling tube of the air spring unit. The damper tube has supporting geometries distributed over its circumference, against which supporting geometries a radially expanded end of the rolling tube is supported. In order to support the rolling tube on the supporting geometries of the damper tube, a torsion element is provided. The torsion element is arranged between the radially expanded end of the rolling tube and the supporting geometries of the damper tube. The torsion element forms a form fit with the supporting geometries for the purpose of torque transmission.
