Description

Die Erfindung betrifft ein aus tiefgezogenen Blechschalen zusammengesetztes Gehäuse gemäss dem Oberbegriff des Anspruchs 1.The invention relates to a composite of deep-drawn sheet metal shells housing according to the preamble of claim 1.

Aus der DE-G 94 20 601 U ist eine Falzverbindung an umlaufenden, aufeinanderliegenden Flanschen von aus tiefgezogenen Schalen zusammengesetzten Blechgehäusen, hier ein Schalldämpfergehäuse, bekannt. Dabei besitzt die eine Blechschale eine schmale Flanschkante, die andere Schale eine breitere Flanschkante. Die breitere Flanschkante ist um die schmälere herumgebogen. Um eine höhere Festigkeit und insbesondere eine Gasdichtigkeit zu erreichen, ist in beide Flansche eine Stufe eingeformt, die entgegengesetzt gerichtet ist zur schmäleren Flanschkante, wobei vorzugsweise das Ende der breiteren Flanschkante in der durch die Stufe gebildeten Nut liegt.From the DE-G 94 20 601 U is a rabbet joint on circumferential, superposed flanges of deep-drawn shells sheet metal housings, here a muffler housing known. The one sheet metal shell has a narrow flange edge, the other shell has a wider flange edge. The wider flange edge is bent around the narrower. In order to achieve a higher strength and in particular a gas tightness, a step is formed in both flanges, which is directed opposite to the narrower flange edge, wherein preferably the end of the wider flange edge is located in the groove formed by the step.

Ein gewisser Nachteil dieser Falzkonstruktion ist der relativ hohe Blechbedarf einerseits und die Mehrstufigkeit bei der Herstellung der Falzverbindung. Auch ist die Verbindung nicht gasdicht.A certain disadvantage of this folding construction is the relatively high sheet metal requirement on the one hand and the multiple stages in the production of the seam connection. Also, the connection is not gas-tight.

Aus der DE-G 87 01 980 U ist eine weitere Gehäusekonstruktion bekannt, ebenfalls für einen Schalldämpfer. Auch hier besteht das Gehäuse aus zwei tiefgezogenen Blechhalbschalen. Die Ränder der Halbschalen sind so ausgebildet, dass sie mehr oder weniger tief ineinander gesteckt werden können. Dadurch ist ein gewisser Toleranzausgleich möglich. Die Verbindung der beiden Halbschalen erfolgt ausschliesslich durch Schweissen. Schweissen führt jedoch zu einer Gefügeveränderung.From the DE-G 87 01 980 U Another housing construction is known, also for a silencer. Again, the housing consists of two deep-drawn sheet metal shells. The edges of the half-shells are designed so that they can be more or less deeply inserted into each other. As a result, a certain tolerance compensation is possible. The connection of the two half shells takes place exclusively by welding. Welding, however, leads to a structural change.

Nach der US 4,131,980 A ist ein gefalzter Tank für Flüssigkeiten bekannt, bei dem in die Bördelung Klebstoff zum Abdichten eingebracht ist.After US 4,131,980 A is a folded tank for liquids is known in which in the flange adhesive for sealing is introduced.

In der EP 0 992 659 A2 wird ein Abgasleitelement mit einem Auspuff, mit mindestens zwei Zuleitungen und einer Wandung mit zwei Verbund-Wandelementen beschrieben. Jedes Wandelement besitzt zwei einstückige, metallische Schalen und eine zwischen diesen angeordnete Schicht wärmedämmendes Isoliermaterial. Die Schalen können durch Schweißen und/oder Hartlöten und/oder Kleben und/oder Bördeln miteinander verbunden werden.In the EP 0 992 659 A2 An exhaust element is described with an exhaust, with at least two leads and a wall with two composite wall elements. Each wall element has two one-piece, metallic shells and a layer arranged between them insulating insulating material. The shells may be joined together by welding and / or brazing and / or gluing and / or crimping.

Nach der Entgegenhaltung DE 10 2004 015 814 A1 wird ein Mantelrohr als Gehäuse mit einem Abgasbehandlungskörper auf Basis von Keramik verklebt. Dabei ersetzt der Klebstoff die Lagermatte. Hierzu wird ein Keramikklebstoff auf Stahlbasis eingesetzt.After the citation DE 10 2004 015 814 A1 a jacket tube is glued as a housing with an exhaust treatment body based on ceramic. The adhesive replaces the bearing mat. For this purpose, a ceramic adhesive based on steel is used.

In der DE 103 25 030 A1 wird ein Hohlkörper wie beispielsweise ein Gehäuse aus einem faserverstärkten keramischen Verbundwerkstoff hergestellt. Die Herstellung solcher Hohlkörper erfolgt mit getränkten Fasermaterialien und faserverstärkten keramischen Verbundwerkstoffen. Ein solches Gehäuse wird mit einem Katalysatorkörper verklebt.In the DE 103 25 030 A1 For example, a hollow body such as a fiber reinforced ceramic composite body is manufactured. The production of such hollow body takes place with impregnated fiber materials and fiber-reinforced ceramic composite materials. Such a housing is bonded to a catalyst body.

Nach der Entgegenhaltung DE 103 28 812 A1 werden das Gehäuse und ein Metallträger und/oder die Metallfolien des Metallträgers miteinander verklebt. Das Gehäuse wird zum Einbringen des Metallträgers gewickelt, so dass die miteinander verklebten Einzelteile durch das Wickeln ummantelt und damit auch zusammengehalten werden.After the citation DE 103 28 812 A1 the housing and a metal carrier and / or the metal foils of the metal carrier are glued together. The housing is wound to introduce the metal support, so that the individual parts glued together are wrapped by the winding and thus held together.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Falzkonstruktion für aus tiefgezogenen Blechschalen zusammengesetzte Gehäuse anzugeben, die trotz geringen Materialaufwands eine hohe Festigkeit und insbesondere Gasdichtigkeit aufweist.The present invention has for its object to provide a folding construction for composite of deep-drawn sheet metal shell housing, which has high strength and in particular gas tightness despite low material costs.

Diese Aufgabe wird gelöst durch ein Gehäuse mit den Merkmalen des Anspruchs 1.This object is achieved by a housing having the features of claim 1.

Dank der Verwendung eines Klebers wird ohne grossen Aufwand im Bereich der Falzverbindung eine völlige Gasdichtigkeit erreicht. Vorteilhafterweise übernimmt der Kleber auch die Verbindung der beiden Halbschalen, so dass die Falzverbindung nur für die Zeit benötigt wird, in der der Kleber noch nicht ausgehärtet ist.Thanks to the use of an adhesive, a complete gas-tightness is achieved in the area of the hinge connection without much effort. Advantageously, the adhesive also takes over the connection of the two half shells, so that the seam connection is required only for the time in which the adhesive has not yet cured.

Ein weiterer Vorteil ist, dass die Kleberschicht auch gewisse Welligkeiten im Bereich der Flansche ausgleichen kann, so dass bei der Herstellung der Halbschalen nicht mehr darauf geachtet werden muss, dass die Flansche völlig eben sind.Another advantage is that the adhesive layer can also compensate for certain ripples in the region of the flanges, so that it no longer has to be taken into account in the production of the half-shells that the flanges are completely flat.

Es versteht sich, dass die eingesetzte Kleberschicht an die Einsatzbedingungen angepasst werden muss. Kleber auf Kunststoffbasis beispielsweise haben eine Temperaturfestigkeit bis zu 300 deg. C.It is understood that the adhesive layer used must be adapted to the conditions of use. For example, plastic-based adhesives have a temperature resistance of up to 300 ° C. C.

Für höhere Einsatztemperaturen wird vorteilhafterweise eine Kleberschicht verwendet, die hoch temperaturfest ist.For higher operating temperatures, an adhesive layer is advantageously used which is highly temperature-resistant.

Vorzugsweise wird für den Hochtemperatureinsatz ein Kleber auf Keramikbasis verwendet. Dies gilt insbesondere dann, wenn der Keramikkleber Zusätze enthält, die mit den Blechoberflächen unter Ausbildung einer Haftschicht reagieren.Preferably, a ceramic-based adhesive is used for the high-temperature use. This is especially true when the ceramic adhesive contains additives that react with the sheet surfaces to form an adhesive layer.

Anhand der Zeichnung soll die Erfindung in Form eines Ausführungsbeispiels rein schematisch erläutert werden.Reference to the drawing, the invention in the form of an embodiment will be explained purely schematically.

Die Figur zeigt einen Querschnitt durch ein Gehäuse, gebildet aus zwei tiefgezogenen Blechschalen 1, 2. Jede Schale 1, 2 besitzt einen umlaufend angeformten Flansch 3, 4. Zwischen den Flanschen 3, 4 ist eine Kleberschicht 5 eingebracht, die die beiden Schalen 1, 2 miteinander verklebt und die Flansche 3, 4 gasdicht verbindet.The figure shows a cross section through a housing formed from two deep-drawn sheet metal shells 1 . 2 , Every shell 1 . 2 has a circumferentially molded flange 3 . 4 , Between the flanges 3 . 4 is an adhesive layer 5 introduced the two shells 1 . 2 glued together and the flanges 3 . 4 connects gas-tight.

Bei dem in der Zeichnung dargestellten Gehäuse handelt es sich um einen Abgaskrümmer oder um ein Katalysator-, Russfilter- oder Schalldämpfergehäuse, welches einen Einlass- oder Auslassstutzen 6 besitzt. In diesen Gehäusen strömen die Abgase von Verbrennungsmotoren mit Temperaturen bis zu 1100 deg. C. Durch die Verwendung einer Kleberschicht 5 auf Keramikbasis wird diesen Temperaturbedingungen entsprochen.The housing shown in the drawing is an exhaust manifold or a catalyst, soot filter or muffler housing having an inlet or outlet port 6 has. In these cases, the exhaust gases of internal combustion engines flow with temperatures up to 1100 deg. C. By using an adhesive layer 5 On a ceramic basis, these temperature conditions are met.
