FLANGE PLATE |
摘要 |
A flange plate for a manifold of an exhaust-gas system for internal combustion engines, which flange plate can be fixed via at least one holding device to an exhaust-gas outlet connecting piece of the internal combustion engine by a first outer layer, formed as a mounting layer, which can be placed at least partially directly or indirectly against the exhaust-gas outlet connecting piece via a seal, and the flange plate can be applied to the holding device by a second outer layer, formed as a holding layer, in order to generate a holding force F, acting at a right angle to the mounting layer, for sealingly placing the mounting layer against the exhaust-gas outlet connecting piece, and the flange plate having at least a first intermediate layer which is arranged, relative to the holding force F, between the mounting layer and the holding layer. Here, the first intermediate layer is formed as a cavity structure, wherein the cavity structure has single- or multiple-part wall parts which extend in a direction parallel to the mounting layer and are arranged adjacent to one another, the wall parts having a width b1, measured in a direction parallel to the mounting layer, and having a height h1, measured in a direction at a right angle to the mounting layer, where h1>b1, wherein the different wall parts delimit a plurality of cavities which are open towards the mounting layer or towards the holding layer or, together with the mounting layer and the holding layer, delimit an open-ended channel. |

1. A flange plate for a manifold of an exhaust-gas system for internal combustion engines, comprising: the flange plate which can be fixed via at least one holding device to an exhaust-gas outlet connecting piece of the internal combustion engine by a first outer layer, formed as a mounting layer, which can be placed at least partially directly or indirectly against the exhaust-gas outlet connecting piece via a seal, said flange plate being applicable to the holding device by a second outer layer, formed as a holding layer, in order to generate a holding force F, acting at a right angle to the mounting layer, for sealingly placing the mounting layer against the exhaust-gas outlet connecting piece, said flange plate having at least a first intermediate layer which is arranged, relative to the holding force F, between the mounting layer and the holding layer,
wherein the first intermediate layer is formed as a cavity structure, wherein the cavity structure has single- or multiple-part wall parts which extend in a direction parallel to the mounting layer and are arranged adjacent to one another, said wall parts having a width b1, measured in a direction parallel to the mounting layer, and having a height h1, measured in a direction at a right angle to the mounting layer, where h1>b1, wherein the single- or multiple-part wall parts a) delimit a plurality of cavities which are open towards the mounting layer or towards the holding layer or b) delimit, together with the mounting layer and the holding layer, an open-ended channel. |
