ABSTRACT:
Pneumatic spring comprising an elastic expansion bellows, a receptacle fastened to the expansion bellows, at least one fastening element between the expansion bellows and the receptacle, a point where it is attached to the vehicle chassis, a piston rod of a shock absorber which has a shock absorber outer tube, which represents an unrolling surface for the expansion bellows, and connection mechanisms on the piston rod and on the shock absorber outer tube respectively for the attachment of the pneumatic spring shock absorber unit inside a vehicle chassis, characterized by the fact that the expansion bellows has a connecting piece which is braced against a piston-rod-side end surface of the shock absorber outer tube and that the receptacle has a cover, which interacts with a seal and which is braced against an axial mounting surface, which executes a relative motion in relation to the outer tube of the shock absorber identical to the motion executed by the vehicle body, whereby the axial fastening of the pneumatic spring is achieved by the system pressure inside the pneumatic spring by way of the locking piece and the cover piece.
