Embodiment Construction

[0065] figure 1 A bearing 1 is shown which comprises a first cover plate 2 and a second cover plate 3 , wherein an elastomer layer 4 is arranged between the first cover plate 2 and the second cover plate 3 . Reinforcing fibers 5 are assigned to the elastomer layer 4 . The bearing 1 exhibits two stiffness values ​​in two mutually orthogonal directions, wherein the stiffness values ​​differ by a factor of up to 15,000.

[0066] Reinforcing fibers 5 surround and surround the elastomeric layer 4 . The reinforcing fibers 5 run over the outer circumference of the elastomer layer 4 , which is accommodated in a clamping manner between the cover 2 and the cover 3 . The reinforcing fibers 5 are thus not part of the elastomer layer 4 but are made of a different material than the elastomer layer 4 .

[0067] The elastomer layer 4 has in its interior recesses 6 which are filled with gas 7 and liquid 8 .

[0068] figure 2 A bearing 1 ′ is shown in which a gas chamber 7 a and a liquid ...

Abstract

The invention relates to a bearing (1, 1', 1", 1"'), comprising a first cover plate (2) and a second cover plate (3), wherein the first cover plate (2) and the second An elastomer layer (4) is arranged between the cover plates (3). The object of the present invention is to design and improve a bearing of the above-mentioned type in such a way that it can be manufactured cost-effectively and have a long service life. The bearing is characterized in that reinforcing fibers (5) are assigned to the elastomer layer (4).

Description

technical field [0001] The invention relates to a bearing according to the preamble of claim 1 . Background technique [0002] It is known from the prior art to incorporate continuous fibers in the form of rovings as reinforcement in elastomers. The continuous fibers are used, for example, as reinforcement material in V-belts or as fabrics in hoses, tires and air spring bladders. [0003] Furthermore, bearings in the form of multi-layer springs are also known from the background art. The multilayer spring has a rubber-metal structure. EP 2 360 388 A discloses a multilayer spring of the type mentioned above. [0004] from the literature" Structural bearings are known from ELASTOMERLAGER - Konzeption und Bemessung" ("Fiber reinforced elastomer bearings - concept and design") (Ulrich Gerhaher; Vienna, August 2010). [0005] The hitherto known multilayer bearings are expensive, since a large number of metal sheets have to be produced. Furthermore, the bearings are particu...
