• the air spring rolling bellows comprising two open ends, at least at one of its two open ends, having a bead ring and fastened in an airtight manner to an air spring cover connected to the sprung mass;
• the rolling bellows fastened in an airtight manner by way of its other open end to a connection part connected to the unsprung mass;
• the air spring cover, connection part and rolling bellows delimiting a working space filled with compressed air, wherein at least the airtight connection between the air spring rolling bellows and the air spring cover is effected by means of a connecting element which is fastened to the bead ring in a materially bonded and/or positively locking manner, wherein the connecting element is configured in the form of a screw ring inserted into the bead ring, the screw ring is provided with an external thread and can be screwed into a complementary internal thread provided in the air spring cover.
