摘要： The invention relates to a pneumatic spring (1) for axles of vehicles with air suspension, comprising a plunger piston (5) which can be fixed to an axle, an upper closure cover (2) which can be fixed to the vehicle and which comprises rolling bellows (3) secured to the cover, and a bead (32) which is formed on the rolling bellows (3) and which is fixed to the upper face (13) of the plunger piston (5) by a ring (6). The aim of the invention is to allow a simple, non-detachable, and pressure-tight fixation of the rolling bellows (3) to the plunger piston (5) with a pneumatic spring (1) and to allow a fully automatic assembly. According to the invention, this is achieved in that the ring (6) is secured against the plunger piston (5) via a rotational mechanism formed on the ring (6) and on the plunger piston (5).

摘要： The present invention discloses an air spring design wherein the second retainer plate utilized in some conventional designs is eliminated. This accomplishes the objective of reducing the manufacturing cost of the air spring as well as its weight. The air springs of this invention also offer an advantage over conventional air springs that do not include a second retainer plate in that the flexible member of the air spring cannot be detached from the piston. The subject invention more specifically discloses an air spring which is comprised of a retainer plate, a piston, and an elastomeric sleeve, wherein the elastomeric sleeve is sealingly engaged with the first retainer plate and the piston to define a pressurizable chamber, wherein the piston has a wall which provide a surface on which the elastomeric sleeve rolls during compression, wherein the piston has a bead seal which extends from the piston wall toward the center of the air spring to provide a surface onto which the elastomeric sleeve is crimped with a crimp ring which extends from the bead seal.

摘要： 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 Ü, and the external guide 7 is attached in the region of the overlap Ü of the layer cover 9 to the air spring bellows 2 by means of an external clamping element 10.
