Air spring and method for turning up an air spring bellows of an air spring

The invention relates to an air spring for chassis of vehicles, which is clamped with an air spring piston and an air spring cover 3 between the chassis and vehicle body of a motor vehicle, comprising an air spring bellows 2 made from elastomeric material which at least partially delimits a compressed air-filled working chamber 1 and which, forming at least one rolling fold 4, rolls on the air spring piston, wherein the air spring bellows 2 is attached by means of clamping elements 5 at a first end 6 to the air spring cover 3 and at a second end to the air spring piston, comprising an external guide 7 which is attached to the air spring bellows 2 and spaced apart from the air spring cover 3 and which is attached to the air spring bellows 2 in such a way that a partial piece of the air spring bellows 2 is formed between the air spring cover 3 and the external guide 7 as a cardanic fold 8 which permits a deflection of the air spring bellows 2 produced by forces acting perpendicular to the axis of the air spring bellows 2. According to the invention, the air spring bellows 2 has a layer cover 9 at the first end 6, said layer cover being inverted back over such a length that, after assembly of the air spring, the layer cover 9 partially covers the external guide 7 with an overlap, and the external guide 7 is attached in the region of the overlap of the layer cover 9 to the air spring bellows 2 by means of an external clamping element 10.
