Definitions

the present invention relates to a silencer for an exhaust system of an internal combustion engine, in particular of a motor vehicle.
the invention further relates to an exhaust system with such a silencer and an internal combustion engine with such an exhaust system.
Silencers typically include a housing that encloses a muffler volume, and at least one inlet tube and at least one outlet tube.
the muffler can then be fluidly connected to the rest of the exhaust system via the inlet pipe and the outlet pipe.
the muffler may also comprise at least one holding element with which the muffler can be attached to a support structure, for example the internal combustion engine of a motor vehicle.
a support structure for example the internal combustion engine of a motor vehicle.
the present invention addresses the problem of providing a muffler of the type mentioned an improved embodiment, which is particularly suitable for the realization of a lightweight construction.
the silencer according to the invention has at least one sandwich plate, wherein this sandwich plate forms a part of a housing shell of the housing of the silencer.
the muffler further comprises a self-supporting support structure, which in turn comprises a tube assembly which is at least partially disposed in the housing interior.
This pipe arrangement may comprise, for example, an exhaust gas supply line and an exhaust gas discharge line, by means of which exhaust gas from an exhaust system of an internal combustion engine including the sound to be damped supplied to the muffler and can be discharged therefrom again.
the tube assembly can be supported mechanically stable in the housing of the muffler.
the sandwich panel according to the invention can be used, which is flat for optimum attachment of the muffler to the subfloor and yet has a very high mechanical stability.
the silencer according to the invention can also be mounted in the space in a motor vehicle usually spatially very limited space and, if necessary, this form correspondingly flat.
each such sheet metal panel layer may have a thickness of about 0.1 mm, the total weight of such a sandwich panel compared to conventional sheet metal walls with a thickness of sheet metal wall 1.5 mm significantly reduced and thus particularly suitable for stiffening large areas.
sandwich panels in silencers (instead of conventional sheet metal walls) can thus achieve a significant weight savings.
the silencer according to the invention can thus be made in lightweight construction, while ensuring at the same time is that necessary for the absorption and transmission of the muffler supplied forces or mechanical bending moments necessary mechanical stability is present.
the at least one sandwich panel is part of the self-supporting support structure. This allows a particularly good transmission of forces or torques supplied to the muffler via the self-supporting support structure, for example to a discharge line of the pipe arrangement.
the self-supporting support structure may comprise at least one intermediate floor.
Such an intermediate floor can be used to support the pipe arrangement on the self-supporting support structure and thus further improve the mechanical stability of the muffler.
the muffler may include a jacket cover, which completes the first sandwich panel to the housing shell of the housing of the muffler according to the invention. This means that the entire housing of the muffler is formed by the first sandwich panel and such a jacket cover. This allows a mechanically stable, yet technically very easy to manufacture muffler, so that the production cost of such a muffler can be kept relatively low.
the muffler may comprise a further sandwich panel, which is part of the self-supporting support structure, as well as a first and a second sheet metal wall, which together complete the first sandwich panel to the housing shell.
the mechanical stability of the invention Muffler can be further increased, as well as the other sandwich plate as part of the self-supporting support structure in the muffler initiated forces or moments record and forward or can absorb.
the first and second sheet metal wall can each thin-walled, so lightweight, and also be designed and manufactured inexpensively, since the two sheet metal walls have no supporting function and they need not absorb the muffler supplied forces.
the sandwich panel and the further sandwich panel as well as the first and second sheet-metal walls can be arranged substantially opposite one another in a cross-sectional profile of the silencer.
the muffler has a first and a second end floor, which complete the housing shell to the housing.
the first or second end floor can each be adhesively bonded, soldered or welded to the housing jacket, so that the housing jacket with the two end floors forms a gas-tight housing. Since the two end floors have no supporting function, these may also be preferably formed as a thin sheet metal walls.
the jacket cover can be integrally connected to the first and / or to the second end floor.
the jacket hood as well as the first and second end floor form a single workpiece, which can be connected in the manner of a hood with the sandwich panel and in particular this can be welded.
the integral with the first and second end floor connected jacket hood can be designed in the manner of a shell.
the shell hood in a longitudinal section of the muffler have two edge portions for attachment to the at least one sandwich panel which, to the outside, away from the housing interior of the muffler , or inwards, towards the housing interior, stand out.
At least one of the two metal walls can be integrally connected to the first or the second end floor.
the first or / and second end floor of the silencer can each have a first or second through-opening.
the crude arrangement may comprise at least one supply and discharge pipe with a supply or discharge opening, which are performed through the first and second through-openings from the outside into the housing interior, such that the supply or discharge opening in the at least a chamber of the muffler is arranged.
the at least one intermediate bottom can have a first and a second end section, the first end section then being attached to the first sandwich panel and the second end portion can be supported on the other sandwich panel or on the jacket hood.
At least one through-opening may be provided in the intermediate bottom in an area arranged between the two end sections, through which the at least one supply or discharge pipe can be made. In this way, the supply and discharge pipe can be mechanically supported particularly stable in the muffler.
the at least one intermediate floor may be an additional sandwich panel (in addition to the first and second sandwich panels).
a particularly high mechanical stability can be achieved in the silencer according to the invention by means of the additional sandwich plate.
the at least one intermediate floor may also be a sheet metal wall. This variant is particularly preferable when the mechanical stability does not have to be substantially increased by means of the intermediate bottom, so that the sheet metal wall can serve as a pure partition for separating the chamber in the housing interior into a first and second sub-chamber, by means of which in Sound absorber introduced sound can be particularly well damped.
the sandwich panel can be connected to the other sandwich panel or the jacket hood by means of welding, gluing or soldering.
the at least one sandwich panel in a longitudinal section profile of the muffler can have a first and second end section with respect to the longitudinal direction, in which a wall thickness of the sandwich panel has a lower value than in one arranged between the two end sections Area of the sandwich panel.
the sandwich panel can then be riveted to the two end portions with complementary to these two end portions edge portions of the jacket cover.
the invention further relates to an exhaust system, in particular for an internal combustion engine of a motor vehicle, with an exhaust gas removal pipe for discharging exhaust gas from the exhaust system and with a silencer with one or more of the aforementioned features.
the tube assembly of the muffler may have a fluidically connected to the exhaust gas discharge pipe feed pipe.
the present invention further relates to an internal combustion engine with a combustion chamber and an exhaust system with one or more of the aforementioned features, wherein the combustion chamber of the internal combustion engine can be fluidly connected to the exhaust system by means of a connecting pipe.
