Abstract

The housing has an input sided front plate and an output sided front plate. A housing shell comprises of several layers of a thin plate, where the plate is wound on top of each other. The layers of the plate are clamped with a high temperature constant adhesive (2) in an area wise, in an outer end area. The adhesive comprises of a component on a ceramic base, which is hardened.

Description

Die Erfindung betrifft Gehäuse für Schalldämpfer und dergleichen Elemente von Abgasanlagen für Kraftfahrzeuge gemäß dem Oberbegriff des Anspruchs 1.The Invention relates to housing for mufflers and The like elements of exhaust systems for motor vehicles according to the preamble of claim 1.

In jedes Kraftfahrzeug mit Verbrennungsmotor wird eine Abgasanlage eingebaut, deren Aufgabe es ist, die Schadstoffe sowie den Lärm, die vom Verbrennungsmotor ausgehen, auf erträgliche und vom Gesetzgeber vorgegebene Werte zu reduzieren. Jede Abgasanlage enthält mehrere Gehäuse, beispielsweise für Katalysator, Dieselrußfilter, Vor-, Mittel- und Nachschalldämpfer. Jedes Gehäuse besitzt einen Eingang, einen Ausgang, meist als Konus ausgebildet, und einen Gehäusemantel.In Every motor vehicle with an internal combustion engine becomes an exhaust system whose task is to eliminate the pollutants and the noise that emanating from the internal combustion engine, on tolerable and by the legislature to reduce specified values. Each exhaust system contains several Casing, for example Catalyst, diesel soot filter, Forward, middle and rear silencer. Every case has an input, an output, usually designed as a cone, and a housing shell.

Diese Gehäuse können auf unterschiedliche Arten hergestellt werden. Eine weitverbreitete Technik ist die sogenannte Wickeltechnik. Hier besteht das Gehäuse aus einem eingangsseitigen Stirnblech, einem ausgangsseitigen Stirnblech und einem auf die beiden Stirnbleche ausgewickelten Blech als Gehäusemantel. Zum Schließen des Mantels werden die Blechenden verschweißt oder zusammengefaltet. Nach der gleichen Methode erfolgt die Verbindung zwischen dem Mantel und den Stirnblechen.These casing can be made in different ways. A widespread Technology is the so-called winding technique. Here the housing is made an input side face plate, an output side face plate and an unfolded on the two end plates sheet metal as a housing shell. To close of the jacket, the sheet metal ends are welded or folded. To the same method is the connection between the jacket and the front plates.

Damit der Gehäusemantel die nötige Stabilität und Festigkeit hat, muss das verwendete Blech eine Mindeststärke haben. Diese Mindeststärke liegt bei 1,2–1,5 mm. Diese Blechstärke ist auch erforderlich, um das Abstrahlen von Körperschall klein zu halten.In order to the housing jacket the necessary stability and strength, the sheet used must have a minimum thickness. This minimum strength is 1.2-1.5 mm. This sheet thickness is also required to minimize the emission of structure-borne noise.

Zum Minimieren von Körperschall werden oft auch Doppelbleche verwendet. Doppelbleche lassen sich noch schwieriger verarbeiten als dicke Einfachbleche.To the Minimize structure-borne noise Often double sheets are also used. Double sheets can be even more difficult to process than thick single sheets.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Gehäuse für Schalldämpfer und dergleichen Elemente anzugeben, welches erheblich einfacher hergestellt werden kann und gleichzeitig hervorragende akustische Dämpfungseigenschaften besitzt.Of the Present invention is based on the object, a housing for silencers and specify the same elements, which made much easier and at the same time has excellent acoustic damping properties.

Diese Aufgabe wird gelöst durch ein Gehäuse mit dem Merkmal des Anspruchs 1.These Task is solved through a housing with the feature of claim 1.

Die vorliegende Erfindung bildet die derzeit übliche sogenannte Wickeltechnik, bei der ein dickes Blech über nur 360° auf die Stirnfläche gewickelt wird, konsequent weiter, indem ein langes dünnes Blech in mehreren Lagen auf die Stirnbleche gewickelt und anschließend verklebt wird. Das dünne Blech lässt sich leicht wickeln. Die mehreren Lagen bewirken eine hervorragende akustische Dämpfung, so dass derartige Gehäuse praktisch keinen Körperschall mehr abstrahlen.The present invention forms the presently known so-called winding technique, when a thick sheet over only 360 ° up the face is wound up, consistently further, adding a long thin sheet wrapped in several layers on the front panels and then glued becomes. The thin sheet let yourself wrap lightly. The multiple layers produce an excellent acoustic Damping, so that such housing virtually no structure-borne sound emit more.

Außerdem wirken die mehreren Lagen gleichsam als Labyrinthdichtung, so dass eine Verklebung nur des äußeren Blechendes völlig genügt.In addition, act the multiple layers as a labyrinth seal, so that one Gluing only the outer sheet metal end completely enough.

Für die Verwendung als Katalysatorgehäuse, wo eine absolute Gasdichtigkeit verlangt wird, werden die Blechlagen über die ganze Länge und Breite verklebt.For the use as a catalyst housing, where an absolute gas tightness is required, the sheet metal layers on the full length and width glued.

Vorteilhafterweise wird ein Kleber auf Keramikbasis verwendet, der z. B. durch Erwärmen aushärtet.advantageously, a ceramic-based adhesive is used, the z. B. hardens by heating.

Anhand der Zeichnung soll die Erfindung in Form des Ausführungsbeispiels erläutert werden.Based the drawing is intended to illustrate the invention in the form of the embodiment explained become.

Die Figur zeigt in einer perspektivischen Darstellung den Mantel eines Katalysator- oder Schalldämpfergehäuses, der Einfachheit halber ohne die Stirnbleche. Der Gehäusemantel besteht aus zwei einviertel Lagen eines dünnen Blechs 1, welches spiralig übereinander gewickelt ist. Die Blechlagen 1 sind über die ganze Länge mit Hilfe eines hochtemperaturbeständigen Klebers 2, vorzugsweise auf Keramikbasis, verklebt. Dadurch werden guter Halt und Gasdichtheit erreicht.The figure shows a perspective view of the jacket of a catalyst or muffler housing, for simplicity, without the end plates. The housing shell consists of two quarter-inch layers of a thin sheet 1 , which is spirally wound on top of each other. The sheet metal layers 1 are over the entire length with the help of a high temperature resistant adhesive 2 , preferably based on ceramics, glued. This achieves good hold and gas tightness.

Es versteht sich, dass zusätzlich eine Lasernaht oder auch einige wenige Schweißpunkte genügen, um das äußere Blechende zu fixieren, bis der Kleber 2 ausgehärtet ist.It is understood that in addition a laser seam or a few welds are sufficient to fix the outer end of the sheet until the adhesive 2 has hardened.
