Definitions
- the invention relates to an air spring arrangement consisting at least of:
- a bellows made of elastomeric material with two bellows ends, which encloses a volume-elastic air chamber to form a loop;
- a rolling piston which has a second connection area for the other bellows end and also a rolling surface for the loop; such as
- a generic air spring arrangement is widely used in vehicle construction (cars, commercial vehicles and rail vehicles), reference being made in particular to the document DE 10001 018 A1.
- the air spring arrangement can also be equipped with a vibration damper (shock absorber).
- a vibration damper shock absorber
- Such an air spring arrangement is also referred to as an air spring strut.
- an air suspension strut in which an articulated component is attached to the cover in the vicinity of the connection of the air suspension bellows, which allows swiveling movements under pressure, with the formation of a second loop which extends essentially in the radial direction ,
- the articulated component preferably comprises a circumferential support bearing, which consists of a material which, in addition to the articulation function, also ensures an expansion limitation.
- the task now is to provide an air spring arrangement of the generic type with or without vibration damper, in which, in addition to a secure connection of the outer guide to the cover, a large cardanic deflection is also ensured.
- a circumferential fold bearing connects the cover to the outer guide and thereby encloses the air bellows within this connection area, the fold bearing comprising the following components:
- a first holding part which is fastened together with the corresponding bellows end on the cover within the first connection area;
- a second holding part which surrounds at least a portion of the outer surface of the outer guide;
- a fold system which is arranged between the first and second holding part, and which comprises at least a first and second fold, which run inwardly with the formation of at least one constriction, the bellows adapting to the contour of the constriction, furthermore within the constriction a support ring sits.
- Fig. 3 shows a fold bearing with four folds and two constrictions.
- FIG. 1 shows an air spring arrangement 1 with the essential basic components, namely air bellows 2, cover 5 with connection options for the body, Roll-off piston 7 and outer guide 10.
- the cover can be designed as a pressure vessel, optionally in connection with a valve (DE 198 19 642 A1).
- the air bellows 2 made of elastomeric material is usually provided with an embedded reinforcement in the form of an axial bellows (DE 3643 073 A1) or cross-layer bellows (DE 29 04 511 A1).
- the two bellows ends are fastened within the two connection areas 6 and 8 to the cover 5 or rolling piston 7, in particular by means of clamping rings.
- a volume-elastic air chamber 4 is thereby formed.
- a loop 3 is created which can slide along the rolling surface 9.
- the air spring arrangement can be equipped with an additional protective sleeve.
- An outer guide 10 supports the air bellows, which is particularly important when using an axial bellows.
- the generic air spring arrangement with external guidance is therefore mostly used when using an axial bellows.
- the dashed area X where the fold bearing connects the cover 5 to the outer guide 10, will now be explained in more detail with reference to the two FIGS. 2 to 3.
- Fig. 2 shows a circumferential fold bearing 11, which encloses the air bellows 2 within the connection area of the cover 6 (here with contouring) and the outer guide 10, in the sense of a chambering.
- the fold bearing comprises the following components:
- a second holding part 14 which firmly grips around at least a partial area of the outer surface of the outer guide 10;
- a fold system I which is arranged between the first and second holding part and comprises a first fold 15 and second fold 16, which run inwardly with the formation of a single constriction 17, the bellows 2 adapting to the contour of the constriction, furthermore a support ring 18 made of metal or plastic sits within the constriction.
- the two folds merge into one another in the area of the constriction.
- the fold bearing 11 consists of an elastomeric material or a thermoplastic elastomer, in particular in connection with an embedded reinforcement, in particular in the form of axially extending thread reinforcements.
- the fold bearing 11 can consist of a textile material, preferably in the form of a fabric.
- the first holding part 13 of the fold bearing and the corresponding bellows end 12 are fastened to the cover by means of a common clamping ring 19.
- the second holding part 14 of the fold bearing is fastened to the outer guide 10 by means of gluing and / or a clamping ring 20.
- the air bellows 2 and the fold bearing 11 have a common contact surface 21, which is preferably non-adhesive, in particular in connection with at least one vent hole 22. It is expedient if each fold is provided with a vent hole.
- FIG. 3 shows a circumferential fold bearing 23 with a fold system II, which additionally comprises a third fold 24 and fourth fold 25, all four folds taking on an essentially undulating course, with the formation of two constrictions 17, one in each constriction Support ring 18 is seated.
