Embodiment Construction

[0021] figure 1 Shown schematically and in section is a detail of a first exemplary embodiment of an air spring 1 , which is tensioned between the chassis and the body of a motor vehicle with an air spring piston (not shown) and an air spring cover 2 .

[0022] The air spring 1 has an air spring bellows 3 made of an elastomer material, which at least partially delimits a working chamber 4 filled with compressed air, which is fixed sealingly on the air spring cover 2 and on the air spring piston. , and the air spring airbag rolls over the air spring piston forming at least one unshown rolling fold.

[0023] As can be seen in the figure, an end region 5 of the air spring bellows 3 is fastened to the clamping section 7 of the air spring cover 2 by means of a snap ring 6 . The clamping connection between the air spring bellows 3 and the air spring cover 2 is strongly loaded by the internal overpressure in the working chamber 4 of the air spring 1 and the resulting forces indicat...

Abstract

The invention relates to an air spring (1), in particular for vehicles, which is clamped with an air spring piston and an air spring cover (2) between the chassis and the vehicle body of a motor vehicle, comprising an air spring bellows (3), which is sealingly fixed on the air spring cover (2) and air spring piston, is made of an elastomeric material, at least partially delimits a working chamber (4) filled with compressed air, and which unrolls so as to form at least one rolling fold on the air spring piston, wherein an end region (5) of the air spring bellows (3) is secured on a clamping section (7) of the air spring cover (2) by means of a clamping ring (6). An additional ring (9) is provided, which is arranged in the end region (5) of the air spring bellows (3) and outside the clamping section (7) in order to relieve the clamping ring (6), wherein the inner diameter thereof substantially corresponds to an inner diameter of the clamping ring (6).

Description

technical field [0001] The invention relates to an air spring, in particular for a vehicle, which is tensioned with an air spring piston and an air spring cover between the chassis and the body of a motor vehicle, the air spring having a seal fastened to the air spring cover and an air spring bladder on the air spring piston, the air spring bladder is formed from an elastomeric material, the air spring bladder at least partially defines a working chamber filled with compressed air, and the air spring bladder forms at least one rolling fold Rolling on the air spring piston, wherein an end region of the air spring bellows is fastened to the clamping section of the air spring cover by means of a retaining ring. Background technique [0002] Air spring arrangements, also referred to as air springs for short, are already known in various embodiments, which are tensioned between the chassis and the body and which have an air spring bellows which in turn is fastened in a housing co...
