Abstract
A damping element has a container tube which is connected to a rolling tube of an air spring, the rolling tube being connected via a spring bellows acting as a rolling bellows to an outer tube which is arranged concentrically and such that it can move axially with respect to the rolling tube, the spring bellows and the rolling tube bounding a gas chamber provided with a gas filling under pressure. The rolling tube is sealed off with respect to the container tube by an O ring in a groove in the container tube, while, at another point on the container tube, projections are arranged as a stop for a front end of the rolling tube in order to dissipate the axial component of the gas pressure acting on said rolling tube. The assembly of the rolling tube on the container tube and the associated sealing by means of the O ring are achieved simply in a cost-effective manner by pushing the tubes together, the position of the tubes in relation to each other resulting automatically as a result of the projections.
