Description

Die vorliegende Erfindung betrifft eine Komponente für ein Abgassystem mit einem mehrteiligen Gehäuse und mindestens einem darin angeordneten und jeweils von einer Montagematte umgebenen Katalysatorkörper und/oder Filterkörper sowie ein Verfahren zur Herstellung einer solchen Komponente gemäss dem Oberbegriff des jeweiligen unabhängigen Patentanspruchs.The present invention relates to a component for an exhaust system with a multi-part housing and at least one therein arranged and each surrounded by a mounting mat catalyst body and / or filter body and a method for producing such a component according to the preamble of the respective independent claim.

Abgaskatalysatoren und Diesel-Partikelfilter sind speziell für die Automobilindustrie unverzichtbar geworden. Sie umfassen typischerweise ein Gehäuse, in welchem ein Katalysatorkörper und/oder ein Filterkörper - z.B. in Form eines Keramiksubstrats - angeordnet sind. Um den Katalysatorkörper und/oder um den Filterkörper herum ist typischerweise eine Montagematte (z.B. eine Intumeszenzmatte) gelegt, die den Katalysatorkörper und/oder den Filterkörper umgibt, sodass der Spalt zwischen dem Katalysatorkörper und/oder dem Filterkörper und dem Gehäuse von der Montagematte ausgefüllt wird. Das Gehäuse kann dabei mehrere Gehäuseteile umfassen (beispielsweise zwei Gehäuseteile), die nach dem Einbringen des von der Montagematte umgebenen Katalysatorkörpers und/oder Filterkörpers in das eine Gehäuseteil miteinander verbunden werden, z.B. durch Schweissen oder durch mechanische Verbindung.Catalytic converters and diesel particulate filters have become indispensable for the automotive industry. They typically comprise a housing in which a catalyst body and / or a filter body - e.g. in the form of a ceramic substrate - are arranged. A mounting mat (eg an intumescent mat) is typically placed around the catalyst body and / or around the filter body, surrounding the catalyst body and / or the filter body, so that the gap between the catalyst body and / or the filter body and the housing is filled by the mounting mat , The housing may in this case comprise a plurality of housing parts (for example two housing parts), which are connected to one another after the introduction of the catalyst body and / or filter body surrounded by the mounting mat into the one housing part, e.g. by welding or by mechanical connection.

Die Funktion der Montagematte besteht darin, den Katalysatorkörper und/oder den Filterkörper an Ort und Stelle im Gehäuse zu halten, und zwar bei verschiedenen Temperaturen und bei unterschiedlichem Lastbetrieb. Der Katalysatorkörper und/oder der Filterkörper muss also sowohl bei kalten Temperaturen (also z.B. unmittelbar nach dem Start) als auch bei warmen Temperaturen (also z.B. bei einer längeren Fahrt auf der Autobahn) einerseits sicher an Ort und Stelle gehalten werden, andererseits darf die mechanische Belastung des Katalysatorkörpers und/oder des Filterkörpers auch nicht zu gross werden, um Beschädigungen des Katalysatorkörpers und/oder des Filterkörpers zu vermeiden. Bei Verwendung einer Intumeszenzmatte (Quellmatte) als Montagematte muss also die noch nicht aufgequollene Montagematte in der Lage sein, eine Verschiebung des Katalysatorkörpers und/oder des Filterkörpers im Gehäuse zu verhindern, während sie bei der Erwärmung aufquillt (und dabei stets in stärkerem Masse aufquillt als sich das Gehäuse bei der Erwärmung dehnt) und einen festeren Sitz des Katalysatorkörpers und/oder des Filterkörpers im Gehäuse bewirkt, wobei darauf zu achten ist, dass die Kräfte auf den Katalysatorkörper und/oder den Filterkörper nicht so gross werden, dass der Katalysatorkörper und/oder der Filterkörper beschädigt wird.The function of the mounting mat is to keep the catalyst body and / or the filter body in place in the housing, at different temperatures and with different load operation. The catalyst body and / or the filter body must therefore both cold Temperatures (ie, for example, immediately after take-off) as well as at warm temperatures (ie, for a long drive on the highway) on the one hand safely held in place, on the other hand, the mechanical load on the catalyst body and / or the filter body may not be too large be to avoid damage to the catalyst body and / or the filter body. When using a Intumeszenzmatte (swelling mat) as a mounting mat so not yet swollen mounting mat must be able to prevent displacement of the catalyst body and / or the filter body in the housing while it swells when heated (and always swells to a greater extent than the housing expands when heated) and causes a tighter fit of the catalyst body and / or the filter body in the housing, wherein care must be taken that the forces on the catalyst body and / or the filter body are not so great that the catalyst body and / or the filter body is damaged.

Bei der Herstellung eines Abgaskatalysators oder Diesel-Partikelfilters (mehrteiliges Gehäuse) wird ein Katalysatorkörper und/oder ein Filterkörper mit einer Montagematte umwickelt und anschliessend in ein erstes Gehäuseteil eingebracht. Durch Zufügen der weiteren Gehäuseteile wird das Gehäuse zusammengesetzt und in einem weiteren Schritt werden die Gehäuseteile miteinander verbunden, z.B. durch Schweissen oder durch mechanische Verbindung, um ein Entweichen der Abgase zu verhindern.In the production of a catalytic converter or diesel particulate filter (multi-part housing), a catalyst body and / or a filter body is wrapped with a mounting mat and then introduced into a first housing part. By adding the other housing parts, the housing is assembled and in a further step, the housing parts are connected together, e.g. by welding or by mechanical connection, to prevent the exhaust gases from escaping.

Beim Zusammensetzen der Gehäuseteile kann es allerdings vorkommen, dass Teile der Montagematte zwischen die einzelnen Gehäuseteile geraten und somit die Dichtheit des Gehäuses beeinträchtigen.When assembling the housing parts, however, it may happen that parts of the mounting mat between the individual housing parts advised and thus affect the tightness of the housing.

Aufgabe der vorliegenden Erfindung ist es, eine Komponente für ein Abgassystem und ein Verfahren zur Herstellung desselben vorzuschlagen, welche die vorstehend genannten Nachteile nicht aufweisen und insbesondere zuverlässig ein dichtes Verschliessen des Gehäuses ermöglichen.Object of the present invention is to propose a component for an exhaust system and a method for producing the same, which do not have the disadvantages mentioned above and in particular reliably enable a tight closure of the housing.

Diese Aufgabe wird mit Hilfe der erfindungsgemässen Komponente für ein Abgassystem gelöst, wie sie durch die Merkmale des unabhängigen Vorrichtungsanspruchs charakterisiert ist. Vorteilhafte Ausführungsbeispiele der erfindungsgemässen Komponente sind Gegenstand der abhängigen Vorrichtungsansprüche. Insbesondere wird die Aufgabe durch eine Komponente für ein Abgassystem gelöst, welche Mittel umfasst, die so ausgebildet und angeordnet sind, dass sie nach dem Einbringen des jeweiligen von der Montagematte umgebenen Katalysatorkörpers und/oder Filterkörpers in ein erstes Gehäuseteil beim Zusammensetzen des ersten Gehäuseteils und der weiteren Gehäuseteile zu dem Gehäuse das Einklemmen der Montagematte zwischen den Gehäuseteilen verhindern. Somit kann das Gehäuse zuverlässig dicht verschlossen bzw. verbunden werden, da keine Teile der Montagematte zwischen die Gehäuseteile geraten können, welche die Dichtheit des Gehäuses beeinträchtigen könnten.This object is achieved with the aid of the component according to the invention for an exhaust system, as characterized by the features of the independent device claim. Advantageous embodiments of the inventive component are the subject of the dependent device claims. In particular, the object is achieved by a component for an exhaust system, which comprises means which are designed and arranged such that they after introduction of each of the mounting mat surrounded catalyst body and / or filter body in a first housing part in assembling the first housing part and the prevent further housing parts to the housing, the clamping of the mounting mat between the housing parts. Thus, the housing can be reliably sealed or connected, since no parts of the mounting mat can fall between the housing parts, which could affect the tightness of the housing.

Bei einem Ausführungsbeispiel der erfindungsgemässen Komponente umfassen die Mittel zum Verhindern des Einklemmens der Montagematte eine oder mehrere flexible Leitplatten, die im Innenraum des ersten Gehäuseteils angeordnet sind, in welches der von der Montagematte umgebene Katalysatorkörper und/oder Filterkörper eingebracht ist, bevor die Gehäuseteile zusammengesetzt sind. Die eine oder mehreren flexiblen Leitplatten stehen aus dem ersten Gehäuseteil in Richtung auf das bzw. die mit dem ersten Gehäuseteil zusammenzusetzenden Gehäuseteil/Gehäuseteile vor. Sie verhindern, dass Teile der Montagematte zwischen die einzelnen Gehäuseteile des mehrteiligen Gehäuses gelangen können. Insofern ist sichergestellt, dass die einzelnen Gehäuseteile nach dem Zusammensetzen dicht miteinander verbunden werden können. Alternativ wäre es auch denkbar, die Packung bestehend aus Katalysatorkörper und/oder Filterkörper und der Montagematte mit einem Klebeband so zu umwickeln, dass keine Teile der Montagematte zwischen die einzelnen Gehäuseteile des mehrteiligen Gehäuses gelangen können.In one embodiment of the inventive component, the means for preventing the clamping of the mounting mat comprise one or more flexible guide plates, which are arranged in the interior of the first housing part, in which is introduced by the mounting mat surrounded catalyst body and / or filter body before the housing parts are assembled. The one or more flexible guide plates protrude from the first housing part in the direction of the housing part / housing parts to be assembled with the first housing part. They prevent parts of the mounting mat from getting between the individual housing parts of the multi-part housing. In this respect, it is ensured that the individual housing parts can be connected tightly together after assembly. Alternatively, it would also be conceivable to wrap the package consisting of catalyst body and / or filter body and the mounting mat with an adhesive tape so that no parts of the mounting mat can get between the individual housing parts of the multi-part housing.

Bei einem weiteren Ausführungsbeispiel der erfindungsgemässen Komponente sind die eine oder mehreren Leitplatten aus dem gleichen Material wie die Gehäuseteile hergestellt. Es sind somit keine verschiedenen Materialien in der Produktion notwendig und auch die Ausdehnung bei Erwärmung ist ähnlich.In a further embodiment of the inventive component, the one or more guide plates are made of the same material as the housing parts. Thus, no different materials are necessary in the production and also the extent of heating is similar.

Bei einem speziellen Ausführungsbeispiel der erfindungsgemässen Vorrichtung sind die eine oder mehreren Leitplatten an der Innenwand desjenigen Gehäuseteils befestigt, in welches der von der Montagematte umgebene Katalysatorkörper und/oder Filterkörper eingebracht ist, bevor die Gehäuseteile zusammengesetzt sind. Eine Befestigung der Leitplatten an der Innenwand des ersten Gehäuseteils hat den Vorteil, dass die Leitplatten bereits vorgefertigt an dem ersten Gehäuseteil vorhanden sind und nicht in einem zusätzlichen Schritt beim Zusammensetzen des Gehäuses eingebracht werden müssen. Ausserdem verhindern sie, dass beim Einbringen des von der Montagematte umgebenen Katalysatorkörpers und/oder Filterkörpers keine Teile der Montagematte derart aus dem ersten Gehäuseteil hinausragen, dass diese Teile beim Zusammensetzen der weiteren Gehäuseteile zwischen den einzelnen Gehäuseteilen eingeklemmt werden.In a specific embodiment of the device according to the invention, the one or more guide plates are fastened to the inner wall of that housing part into which the catalyst body and / or filter body surrounded by the mounting mat is inserted, before the housing parts are assembled. An attachment of the guide plates on the inner wall of the first housing part has the advantage that the guide plates are already prefabricated on the first housing part and not in one additional step in assembling the housing must be introduced. In addition, they prevent that when introducing the surrounding of the mounting mat catalyst body and / or filter body no parts of the mounting mat protrude from the first housing part such that these parts are clamped when assembling the other housing parts between the individual housing parts.

Wiederum bei einem anderen Ausführungsbeispiel der erfindungsgemässen Komponente sind die eine oder mehreren Leitplatten an der Innenwand des ersten Gehäuseteils durch Punktschweissen befestigt. Das Anbringen der Leitplatten mit Hilfe von Punktschweissungen ist eine fertigungstechnisch zuverlässige und wenig aufwändige Art der Befestigung der Leitplatten an der Innenwand des ersten Gehäuseteils. Grundsätzlich sind aber auch andere Arten der Befestigung (z.B. Kleben, weitere Schweissmethoden, etc.) denkbar. Ebenfalls denkbar ist ein Einklemmen der Leitplatten zwischen der Montagematte und der Innenwand des ersten Gehäuseteils ohne Befestigung der Leitplatten an der Innenwand des ersten Gehäuseteils. In der Praxis wird dies dadurch erreicht, dass die Leitplatten in dem ersten Gehäuseteil festgehalten werden, bis der von der Montagematte umgebene Katalysatorkörper und/oder Filterkörper eingebracht worden ist. Nun sind die Leitplatten zwischen der Montagematte und der Innenwand des ersten Gehäuseteils festgeklemmt, so dass das Gehäuse durch Anbringen der weiteren Gehäuseteils zusammengesetzt werden kann und anschliessend die Gehäuseteile zu einem Gehäuse verbunden werden können.Again, in another embodiment of the inventive component, the one or more guide plates are fixed to the inner wall of the first housing part by spot welding. The attachment of the guide plates by means of spot welds is a manufacturing technology reliable and less expensive way of fastening the guide plates on the inner wall of the first housing part. In principle, however, other types of attachment (eg gluing, welding methods, etc.) are conceivable. Also conceivable is pinching the guide plates between the mounting mat and the inner wall of the first housing part without attachment of the guide plates on the inner wall of the first housing part. In practice, this is achieved by holding the guide plates in the first housing part until the catalyst body and / or filter body surrounded by the mounting mat has been introduced. Now, the guide plates are clamped between the mounting mat and the inner wall of the first housing part, so that the housing can be assembled by attaching the other housing part and then the housing parts can be connected to form a housing.

Schliesslich umfasst die erfindungsgemässe Komponente bei einem weiteren Ausführungsbeispiel zwei Katalysatorkörper oder zwei Filterkörper, oder einen Katalysatorkörper und einen Filterkörper. Insbesondere die zuletzt genannte Kombination eines Katalysatorkörpers und eines Filterkörpers in einem gemeinsamen Gehäuse ermöglicht die Herstellung kombinierter Katalysator/Partikelfilter-Komponenten.Finally, in another embodiment, the component according to the invention comprises two catalyst bodies or two filter bodies, or a catalyst body and a filter body. In particular, the last-mentioned combination of a catalyst body and a filter body in a common housing enables the production of combined catalyst / particle filter components.

Das erfindungsgemässe Verfahren zur Herstellung einer Komponente für ein Abgassystem, bei welchem mindestens ein von einer Montagematte umgebener Katalysatorkörper und/oder Filterkörper in ein mehrteiliges Gehäuse eingebracht wird, umfasst die folgenden Schritte:

  • Bereitstellen von Mitteln, die so ausgebildet und angeordnet sind, dass sie nach dem Einbringen des jeweiligen von der Montagematte umgebenen Katalysatorkörpers und/oder Filterkörpers in das erste Gehäuseteil beim Zusammensetzen der Gehäuseteile zu dem Gehäuse das Einklemmen der Montagematte zwischen den Gehäuseteilen verhindern
  • Einbringen des jeweiligen von der Montagematte umgebenen Katalysatorkörpers und/oder Filterkörpers in das erste Gehäuseteil
  • Zusammensetzen des ersten Gehäuseteils mit den weiteren Gehäuseteilen
  • Verbinden der zusammengesetzten Gehäuseteile zu dem Gehäuse.
The inventive method for producing a component for an exhaust system, in which at least one of a mounting mat surrounded catalyst body and / or filter body is introduced into a multi-part housing, comprising the following steps:
  • Providing means which are designed and arranged such that they prevent the clamping of the mounting mat between the housing parts after the introduction of the respective of the mounting mat surrounded catalyst body and / or filter body in the first housing part when assembling the housing parts to the housing
  • Introducing the respective catalyst body and / or filter body surrounded by the mounting mat into the first housing part
  • Assembling the first housing part with the other housing parts
  • Connecting the assembled housing parts to the housing.

Vorteilhafte Varianten des erfindungsgemässen Komponente sind Gegenstand der abhängigen Verfahrensansprüche. Deren Vorteile wurden jeweils bereits vorstehend bei der Erläuterung der korrespondierenden abhängigen Vorrichtungsansprüche erwähnt.Advantageous variants of the inventive component are the subject of the dependent method claims. Their advantages have already been mentioned above in the explanation of the corresponding dependent device claims.

So werden bei einer Verfahrensvariante als Mittel zum Verhindern des Einklemmens der Montagematte eine oder mehrere flexible Leitplatten verwendet, die im Innenraum desjenigen Gehäuseteils angeordnet sind, in welches der von der Montagematte umgebene Katalysatorkörper und/oder Filterkörper eingebracht wird, bevor die Gehäuseteile zusammengesetzt werden. Die eine oder mehreren flexiblen Leitplatten stehen aus dem Gehäuseteil in Richtung auf das mit diesem Gehäuseteil zusammenzusetzende Gehäuseteil vor und werden beim Zusammensetzen der Gehäuseteile gegen die Montagematte gedrückt.Thus, in one variant of the method, one or more flexible guide plates are used as means for preventing the mounting mat from being arranged in the interior of that housing part into which the catalyst body and / or filter body surrounded by the mounting mat is inserted before the housing parts are assembled. The one or more flexible guide plates project from the housing part in the direction of the housing part to be assembled with this housing part and are pressed against the mounting mat when the housing parts are assembled.

Bei einer weiteren Verfahrensvariante sind die Leitplatten, die verwendet werden, aus dem gleichen Material wie die Gehäuseteile hergestellt.In a further variant of the method, the guide plates that are used are made of the same material as the housing parts.

Bei einer speziellen Verfahrensvariante werden die eine oder mehreren Leitplatten an der Innenwand des ersten Gehäuseteils befestigt.In a special variant of the method, the one or more guide plates are fastened to the inner wall of the first housing part.

Insbesondere werden bei einer weiterenIn particular, in another
