Layer structure of at least one elastomeric material with fibers embedded therein, method for producing the layer structure and air spring bellows with such a layer structure

摘要

The invention relates to a layer structure (14) made of at least one elastomeric material (82, 86, 102, 104) with fibers embedded therein, for example for the production of an air spring bellows (12) of an air spring (10), with at least two fabric layers (62, 64) and two cover layers (60, 66), in which the first fabric layer (62) is connected to the second fabric layer (64) and to the inside (76) of the first cover layer (60), and in which the second fabric layer (64) is connected to the inside (77) of the second cover layer (66) is connected, the first fabric layer (62) with a first support fabric (80) embedded in an elastomeric material (82) and the second fabric layer (64) with an elastomeric material ( 82) or in another elastomeric material (86) embedded second supporting fabric (84) is formed. It is provided here that the second cover layer (66) has a sealing layer (90) and an adhesion promoting layer (92), between which a textile connecting layer (94) is arranged for the mechanical interlocking of the sealing layer and the adhesion promoting layer, the sealing layer being largely diffusion-proof elastomeric material (102) and the bonding layer (92) is formed from a highly adhesive elastomeric material (104) that adheres well to the second fabric layer (64). The invention also relates to an air spring bellows, an air spring and a method for producing the above-mentioned layer structure.
