Abstract

The invention relates to an article comprising a main body (6, 7, 8) that consists of a polymer material having elastic properties, particularly an air spring bellows (2), a metal-rubber element or a vibration damper. In order for fire-retardant properties to be improved, the article is provided, partially or fully, with a cover (9) formed from at least one flat textile structure and/or at least one three-dimensional textile structure and/or at least one shrink film. The cover can be fire-retardant itself or can be equipped to be fire-retardant.

Claims

1.-6. (canceled)

7. An article comprising a main body comprised of a polymeric material having elastic properties, wherein the article has a surface which is at least partially covered with at least one cover, and wherein the cover is formed from one or more of a sheetlike textile construct a spacelike textile construct, and/or a shrink film.

8. The article as claimed in claim 7, wherein the cover is formed from a shrink film.

9. The article as claimed in claim 8, wherein the shrink film is configured as a shrink tube.

10. The article as claimed in claim 7, wherein the cover is formed from a sheetlike textile construct.

11. The article as claimed in claim 7, wherein the cover is formed from a spacelike textile construct.

12. The article as claimed in claim 7, wherein the cover has a fire-retardant finish.

13. The article as claimed in claim 12, wherein the fire-retardant finish is based on at least one flame-retardant substance.

14. The article as claimed in claim 7, wherein that the cover is in direct contact with the article surface.

15. The article as claimed in claim 7, wherein the cover is not in direct contact with the article surface.

16. An article comprising a main body comprised of a polymeric material having elastic properties, wherein the article has a surface which is at least partially covered by at least one cover, and wherein the cover comprises a weave having a finish with at least one flame-retardant agent.

17. The article as claimed in claim 16, wherein the cover is formed from a shrink film.

18. The article as claimed in claim 17, wherein the shrink film is configured as a shrink tube.

19. The article as claimed in claim 16, wherein the cover is formed from a sheetlike textile construct.

20. The article as claimed in claim 16, wherein the cover is formed from a spacelike textile construct.

21. The article as claimed in claim 16, wherein that the cover is in direct contact with the article surface.

22. The article as claimed in claim 16, wherein the cover is not in direct contact with the article surface.

23. An air spring bellows comprising a polymeric material having elastic properties, wherein the air spring bellows has a surface which is at least partially covered with at least one cover, and wherein the cover is formed from one or more of a sheetlike textile construct a spacelike textile construct, and/or a shrink film.

24. The air spring bellows as claimed in claim 23, wherein the cover comprises a weave having a finish with at least one flame-retardant agent.

25. The air spring bellows as claimed in claim 23, wherein the cover is formed from a shrink film.

26. The air spring bellows as claimed in claim 25, wherein the shrink film is configured as a shrink tube.

Description

[0070] The invention is now more particularly described by means of exemplary embodiments with reference to schematic drawings, where:

[0071] FIG. 1 shows an air spring arrangement;

[0072] FIG. 2 shows the layered construction of an air spring bellows comprising a cover composed of a weave having a flame-retardant finish.

[0073] FIG. 1 shows an air spring arrangement 1 comprising an air spring bellows 2 and also the two connection components in the form of lid 3 and rolling piston 4, to form an elastic-volume air chamber 5.

[0074] FIG. 2 then shows the layered construction of a finalized air spring bellows 2. This air spring bellows consists of an inner layer 6 and an outer layer 7 as elastic main body, for example composed of a vulcanized mixture of rubber based on NR, a strength member layer 8, for example in the form of a polyamide weave, embedded between the inner layer 6 and the outer layer 7, and also of a cover 9, which is in direct contact with the outer layer 8. The cover 9 in the form of a weave has a finish with at least one flame-retardant agent.
