An air spring has a roll-off piston (1) and a rolling-lobe flexible member
(2) of rubber or rubber-like material. At least the opening of the
rolling-lobe flexible member, which lies opposite the opening assigned to
the roll-off piston (1), is closed air tight with an attachment part (3)
and the attachment part has a planar connecting region (4) having at
least one air connection (7) and an outer rim (11) and a conical region
(10) facing toward the rolling-lobe flexible member (2). The rolling-lobe
flexible member (2) is tightly vulcanized to the attachment part (3) in a
vulcanization region (12) which extends from the side (9) of the outer
rim (11) into the conical region (10). The side (9) of the outer rim (11)
faces toward the rolling-lobe flexible member (2). The at least one
attachment part (3), which is vulcanized to the rolling-lobe flexible
member (2), is configured as a head plate (3) complete with all
connections (7) and is made of thermoplastic or duroplastic synthetic
material.
