Description

Die vorliegende Erfindung betrifft eine Abgasbehandlungsanordnung, die beispielsweise im Abgasströmungsweg einer Brennkraftmaschine eines Kraftfahrzeugs angeordnet werden kann, um aus den eine Brennkraftmaschine verlassenen Abgasen Rußpartikel herauszufiltern bzw. die Abgase einer katalytischen Reaktion zu unterziehen.The present invention relates to an exhaust gas treatment arrangement which can be arranged, for example, in the exhaust gas flow path of an internal combustion engine of a motor vehicle to filter soot particles out of the exhaust gases leaving an internal combustion engine or to subject the exhaust gases to a catalytic reaction.

In den Abgasströmungsweg einer von Brennkraftmaschinen integrierte Abgasbehandlungsanordnungen sind im Allgemeinen mit einem im Wesentlichen zylindrisch, beispielsweise kreiszylindrisch ausgebildeten, sich entlang einer Trägerlängsachse erstreckenden, rohrartigen Träger aufgebaut. Dieser Träger ist mit zwei z. B. im Wesentlichen identischen Trägerelementen, allgemein auch als Halbschalen bezeichnet, ausgebildet. Die Trägerelemente weisen jeweilige vom ersten axialen Endbereich des herzustellenden Trägerkörpers zum zweiten axialen Endbereich desselben sich im Wesentlichen parallel zur Trägerlängsachse erstreckende Verbindungsabschnitte auf. Beim Zusammensetzen eines Trägerkörpers einer so aufgebauten Abgasbehandlungsanordnung wird zunächst in einem der Trägerelemente ein beispielsweise als Rußpartikelfilterelement oder als Katalysatorelement ausgebildetes Abgasbehandlungselement angeordnet, wobei das Abgasbehandlungselement an seinem Außenumfangsbereich von wenigstens einer Lage von dieses im fertiggestellten Trägerkörper fest arretierende Fasermaterial umgeben ist. Nachfolgend wird das andere Trägerelement auf das das Abgasbehandlungselement bereits enthaltende Trägerelement in einer Zusammenführbewegungsrichtung zu bewegt, wobei die Verbindungsabschnitte der beiden Trägerelemente jeweils im Wesentlichen in einer zur Zusammenführbewegungsrichtung orthogonal stehenden Ebene angeordnet sind. Am Ende der Aufeinanderzubewegung der beiden Trägerelemente kommen deren Verbindungsabschnitte in gegenseitigen Kontakt, so dass mit den jeweils sich berührenden Verbindungsabschnitten zwei Verbindungsbereiche gebildet sind, in welchen die beiden das von Fasermaterial umgebene Abgasbehandlungselement zwischen sich einschließenden und festhaltenden Trägerelemente beispielsweise durch Verschweißung miteinander verbunden werden können.In the exhaust gas flow path of an integrated exhaust treatment arrangements of internal combustion engines are generally constructed with a substantially cylindrical, for example circular cylindrical, extending along a support longitudinal axis, tubular support. This carrier is with two z. B. substantially identical carrier elements, also commonly referred to as half shells formed. The carrier elements each have connecting portions extending from the first axial end region of the carrier body to be produced to the second axial end region of the carrier body and extending substantially parallel to the carrier longitudinal axis. When assembling a carrier body of an exhaust treatment arrangement constructed in this way, an exhaust gas treatment element designed, for example, as a soot particle filter element or catalyst element is firstly arranged in one of the carrier elements, wherein the exhaust gas treatment element is surrounded on its outer peripheral region by at least one layer of this fiber material firmly locking in the finished carrier body. Subsequently, the other carrier element is moved towards the carrier element already containing the exhaust gas treatment element in a direction of convergence, wherein the connecting sections of the two carrier elements are each arranged essentially in a plane orthogonal to the direction of movement of the merging movement. At the end of the Aufeinanderzubewegung of the two support members whose connecting portions come into mutual contact, so that two connecting portions are formed with the respective contacting connecting portions, in which the two surrounded by fiber material exhaust treatment element can be connected to each other between themselves by enclosing and retaining carrier elements, for example by welding.

Bei Herstellung einer Abgasbehandlungsanordnung in der vorangehend beschriebenen Art und Weise besteht das Problem, dass Fasern des das Abgasbehandlungselement umkleidenden Fasermaterials sich in den Bereich zwischen zwei in Kontakt miteinander gebrachten Verbindungsabschnitten hinein bewegen bzw. dort eingeklemmt werden. Da dies eine stabile und insbesondere auch abgasdichte Verbindung der beiden Trägerelemente erschwert bzw. verhindert, müssen vor dem endgültigen Aufeinanderzubewegung im Allgemeinen manuell die Fasern des Fasermaterials so nach innen gepresst werden, dass sie nicht in den Stoßbereich der miteinander zu verbindenden Verbindungsabschnitte der beiden Trägerelemente ragen.When manufacturing an exhaust gas treatment arrangement in the manner described above, there is the problem that fibers of the fiber material coating the exhaust gas treatment element move into or become trapped in the region between two connecting sections brought into contact with one another. Since this makes a stable and in particular also gas-tight connection of the two carrier elements difficult or impossible, the fibers of the fiber material must generally be pressed inwards in such a way that they do not protrude into the joint region of the connecting sections of the two carrier elements to be joined together before the final succession movement ,

Aus der DE 199 45 350 A1 ist ein Verfahren zur Herstellung einer Abgasbehandlungsanordnung bekannt. Bei diesem bekannten Verfahren werden zwei beispielsweise zueinander identische Trägerelemente mit näherungsweise U-förmigem Querschnitt eingesetzt, wobei die beiden U-Schenkel jedes Trägerelements, ausgehend von einem diese verbindenden, bogenförmigen Verbindungsbereich, unterschiedliche Längen aufweisen. Jedes der Trägerelemente weist an seinem kürzeren U-Schenkel einen abgesetzten Längsrand auf, welcher für den längeren U-Schenkel des anderen Trägerelements einen Aufnahmeraum bereitstellt, in welchem dieser verschieblich aufgenommen werden kann. Auf diese Art und Weise können durch Verschieben bezüglich einander die beiden Trägerelemente in eine geeignete Positionierung gebracht werden, um in dem von diesen umschlossenen Innenraum ein in eine Fasermaterialanlage eingebettetes Abgasbehandlungselement aufnehmen zu können.From the DE 199 45 350 A1 For example, a method of manufacturing an exhaust treatment arrangement is known. In this known method two, for example, mutually identical support elements are used with approximately U-shaped cross section, wherein the two U-legs of each support element, starting from a connecting these, arcuate connection region, have different lengths. Each of the support elements has at its shorter U-leg on a remote longitudinal edge, which provides a receiving space for the longer U-leg of the other support member in which it can be slidably received. In this way, the two carrier elements can be brought into a suitable positioning by moving relative to each other in order to be able to receive an exhaust gas treatment element embedded in a fiber material system in the interior space enclosed by the latter.

Es ist die Aufgabe der vorliegenden Erfindung, ein Verfahren zur Herstellung einer Abgasbehandlungsanordnung, insbesondere für einen Abgasströmungsweg einer Brennkraftmaschine, vorzusehen, bei welchem die Ansammlung von Fasern von ein Abgasbehandlungselement umkleidendem Fasermaterial im Kontaktbereich zweier Trägerelemente vermieden wird.It is the object of the present invention to provide a method for producing an exhaust gas treatment arrangement, in particular for an exhaust gas flow path of an internal combustion engine, in which the accumulation of fibers from an exhaust gas treatment element enclosing the fiber material in the contact region of two support elements is avoided.

Gemäß der vorliegenden Erfindung wird die vorangehend angegebene Aufgabe gelöst durch ein Verfahren zur Herstellung einer Abgasbehandlungsanordnung, insbesondere für einen Abgasströmungsweg einer Brennkraftmaschine, wobei die Abgasbehandlungsanordnung einen mit einem ersten Trägerelement und einem zweiten Trägerelement ausgebildeten, entlang einer Trägerlängsachse sich erstreckenden, rohrartigen Trägerkörper mit kreisrunder Umfangskontur mit einem ersten axialen Endbereich und einem zweiten axialen Endbereich und wenigstens ein in dem rohrartigen Trägerkörper unter Zwischenlagerung wenigstens einer Fasermateriallage getragenes Abgasbehandlungselement umfasst, umfassend die Maßnahmen:

  1. a) Bereitstellen des ersten Trägerelements als Halbschale mit einem nach radial außen sich erstreckenden ersten Verbindungsabschnitt und einem nach radial außen sich erstreckenden zweiten Verbindungsabschnitt derart, dass der erste Verbindungsabschnitt und der zweite Verbindungsabschnitt sich im Wesentlichen parallel zur Trägerlängsachse vom ersten axialen Endbereich zum zweiten axialen Endbereich erstrecken,
  2. b) Bereitstellen des zweiten Trägerelements als Halbschale mit einem nach radial außen sich erstreckenden dritten Verbindungsabschnitt und einem nach radial außen sich erstreckenden vierten Verbindungsabschnitt derart, dass der dritte Verbindungsabschnitt und der vierte Verbindungsabschnitt sich im Wesentlichen parallel zur Trägerlängsachse vom ersten axialen Endbereich zum zweiten axialen Endbereich erstrecken,
  3. c) Anordnen des ersten Trägerelements derart, dass der erste Verbindungsabschnitt und der zweite Verbindungsabschnitt in einer Zusammenführbewegungsrichtung zueinander versetzt liegen,
  4. d) Anordnen des zweiten Trägerelements derart, dass der dritte Verbindungsabschnitt und der vierte Verbindungsabschnitt in der Zusammenführbewegungsrichtung zueinander versetzt liegen,
  5. e) Aufeinanderzubewegen des ersten Trägerelements und des zweiten Trägerelements in der Zusammenführbewegungsrichtung derart, dass der erste Verbindungsabschnitt mit dem dritten Verbindungsabschnitt in Kontakt tritt und der zweite Verbindungsabschnitt mit dem vierten Verbindungsabschnitt in Kontakt tritt.
According to the present invention, the object stated above is achieved by a method for producing an exhaust gas treatment arrangement, in particular for an exhaust gas flow path of an internal combustion engine, wherein the exhaust gas treatment arrangement has a tube-shaped carrier body with a circular peripheral contour and formed along a carrier longitudinal axis with a first carrier element and a second carrier element comprising a first axial end region and a second axial end region and at least one exhaust gas treatment element carried in the tubular carrier body with intermediate storage of at least one fiber material layer, comprising the measures:
  1. a) providing the first support member as a half-shell having a radially outwardly extending first connecting portion and a radially outwardly extending second connecting portion such that the first connecting portion and the second connecting portion are substantially parallel to the longitudinal axis of the carrier from the first axial end portion to the second axial end portion extend
  2. b) providing the second carrier element as a half-shell with a radially outwardly extending third connecting portion and a radially outwardly extending fourth connecting portion such that the third connecting portion and the fourth connecting portion are substantially parallel to the carrier longitudinal axis from the first axial end portion to the second axial end portion extend
  3. c) arranging the first carrier element in such a way that the first connection section and the second connection section are offset from each other in a direction of assembly movement,
  4. d) arranging the second support member such that the third connection portion and the fourth connection portion are offset from each other in the merging movement direction,
  5. e) Moving toward each other of the first support member and the second support member in the Zusammenführbewegungsrichtung such that the first connecting portion comes into contact with the third connecting portion and the second connecting portion comes into contact with the fourth connecting portion.

Bei dieser erfindungsgemäßen Vorgehensweise wird aufgrund des bei den jeweiligen Verbindungsabschnitten der Trägerelemente vorhandenen Versatzes in der Zusammenführbewegungsrichtung dafür gesorgt, dass Fasern eines ein Abgasbehandlungselement umkleidenden Fasermaterials in der Endphase der Aufeinanderzubewegung nicht nach außen gezogen, sondern nach innen in Richtung auf das Abgasbehandlungselement zu gepresst werden und sich somit nicht im gegenseitigen Stoßbereich der in Kontakt miteinander tretenden Verbindungsabschnitte ansammeln.In this procedure according to the invention, due to the offset in the merging movement direction present at the respective connecting sections of the carrier elements, fibers of a fiber material covering an exhaust treatment element are not drawn outwardly in the final phase of the stacking movement, but are forced inwardly towards the exhaust gas treatment element and Thus, they do not accumulate in the mutual joint area of the connecting sections that come into contact with each other.

Da ferner erfindungsgemäß die Maßnahmen a) und b) das Bereitstellen des ersten Trägerelements und des zweiten Trägerelements als zueinander vorzugsweise im Wesentlichen identische Blechumformteile umfassen, kann der Trägerkörper einerseits in einfacher und kostengünstiger Art und Weise hergestellt werden, besteht andererseits aber auch aus einem Material, das den im Abgasströmungsweg von Brennkraftmaschinen aufgrund der in den Abgasen transportierten Wärme im Allgemeinen entstehenden hohen Temperaturen standhält.Further, since according to the invention the measures a) and b) comprise the provision of the first carrier element and the second carrier element as mutually preferably substantially identical Blechumformteile, the carrier body can be produced on the one hand in a simple and cost-effective manner, on the other hand, however, also consists of a material which withstands the high temperatures generally generated in the exhaust gas flow path of internal combustion engines due to the heat carried in the exhaust gases.

Um das Entstehen von Kippbewegungen eines oder beider Trägerelemente in der Endphase der Aufeinanderzubewegung vermeiden zu können, wird vorgeschlagen, dass bei Durchführung der Maßnahme e) der erste Verbindungsabschnitt mit dem dritten Verbindungsabschnitt und der zweite Verbindungsabschnitt mit dem vierten Verbindungsabschnitt im Wesentlichen gleichzeitig in Kontakt treten. Dies bedeutet, dass der Versatz des ersten Verbindungsabschnitts bezüglich des zweiten Verbindungsabschnitts im Wesentlichen dem Versatz zwischen dem dritten Verbindungsabschnitt und dem vierten Verbindungsabschnitt entspricht, zumindest in der Endphase der Aufeinanderzubewegung der beiden Trägerelemente.In order to avoid the occurrence of tilting movements of one or both support elements in the final phase of the succession movement, it is proposed that when performing the measure e) the first connection section with the third connection section and the second connection section with the fourth connection section substantially simultaneously come into contact. This means that the offset of the first connection section with respect to the second connection section substantially corresponds to the offset between the third connection section and the fourth connection section, at least in the final phase of the mutual movement of the two support elements.

Das erfindungsgemäße Verfahren umfasst vorteilhafterweise vor der Maßnahme e) eine Maßnahme f) zum Positionieren wenigstens eines von wenigstens einer Lage von Fasermaterial umgebenen Abgasbehandlungselements in dem ersten Trägerelement oder dem zweiten Trägerelement.The inventive method advantageously comprises prior to the measure e) a measure f) for positioning at least one exhaust treatment element surrounded by at least one layer of fiber material in the first carrier element or the second carrier element.

Weiter kann bei dem erfindungsgemäßen Verfahren nach der Maßnahme e) eine Maßnahme g) zum Verbinden des ersten Verbindungsabschnitts mit dem dritten Verbindungsabschnitt und des zweiten Verbindungsabschnitts mit dem vierten Verbindungsabschnitt, vorzugsweise durch Verschweißen, vorgesehen sein.Furthermore, in the method according to the invention after the measure e), provision can be made for a measure g) for connecting the first connection section to the third connection section and the second connection section to the fourth connection section, preferably by welding.

Wenigstens ein Abgasbehandlungselement kann als Rußpartikelfilterelement ausgebildet sein. Alternativ oder zusätzlich kann wenigstens ein Abgasbehandlungselement als Katalysatorelement ausgebildet sein.At least one exhaust gas treatment element can be designed as a soot particle filter element. Alternatively or additionally, at least one exhaust gas treatment element may be formed as a catalyst element.

Die Fig. 1 und 2 zeigen eine nicht erfindungsgemäße Ausgestaltungsform einer allgemein mit 10 bezeichneten Abgasbehandlungsanordnung. Die Abgasbehandlungsanordnung 10 umfasst einen Trägerkörper 12, der im dargestellten Beispiel mit zwei zueinander im Wesentlichen identisch aufgebauten Trägerelementen 14, 16 ausgebildet ist. Die beiden allgemein auch als Halbschalen bezeichneten Trägerelemente 14, 16 sind vorzugsweise als Blechumformteile bereitgestellt und bilden zusammen einen Trägerkörper 12 mit im Wesentlichen rohrartiger, zylindrischer Gestalt, beispielsweise mit kreisrunder oder elliptischer Umfangskontur.The Fig. 1 and 2 show a non-inventive embodiment of a generally designated 10 exhaust treatment device. The exhaust gas treatment arrangement 10 comprises a carrier body 12 which, in the example shown, is formed with two support elements 14, 16 constructed essentially identically to one another. The two carrier elements 14, 16, which are generally also referred to as half-shells, are preferably provided as sheet-metal formed parts and together form a carrier body 12 with substantially tubular, cylindrical shape, for example, with circular or elliptical peripheral contour.

Der Trägerkörper 12 erstreckt sich entlang einer Trägerlängsachse L, welche in der Fig. 1 im Wesentlichen orthogonal zur Zeichenebene steht und in der Fig. 2 in der Zeichenebene liegt. Der Trägerkörper 12 weist einen ersten axialen Endbereich 18 und einen zweiten axialen Endbereich 20 auf. In diesen axialen Endbereichen 18, 20 kann der Trägerkörper 12 mit weiteren Leitungsbereichen eines Abgasströmungswegs einer Brennkraftmaschine verbunden werden.The carrier body 12 extends along a carrier longitudinal axis L, which in the Fig. 1 is substantially orthogonal to the drawing plane and in the Fig. 2 lies in the drawing plane. The carrier body 12 has a first axial end region 18 and a second axial end region 20. In these axial end regions 18, 20, the carrier body 12 can be connected to further line regions of an exhaust gas flow path of an internal combustion engine.

An zwei bezüglich der Körperlängsachse L einander im Wesentlichen diametral gegenüberliegenden Verbindungsbereichen 22, 24 sind die beiden Trägerelemente 12, 14 miteinander fest verbunden. In diesen Verbindungsbereichen 22, 24 weist das erste Trägerelement 14 einen bezüglich der Längsachse L sich im Wesentlichen nach radial außen erstreckenden ersten Verbindungsabschnitt 26 für den ersten Verbindungsbereich 22 sowie einen zweiten Verbindungsabschnitt 28 für den zweiten Verbindungsbereich 24 auf. In entsprechender Weise weist das zweite Trägerelement 16 für den ersten Verbindungsbereich 22 einen bezüglich der Längsachse L sich im Wesentlichen nach radial außen erstreckenden dritten Verbindungsabschnitt 30 und für den zweiten Verbindungsbereich 24 einen vierten Verbindungsabschnitt 32 auf. Der erste Verbindungsabschnitt 26 des ersten Trägerelements 14 liegt im Zusammenbauzustand am dritten Verbindungsabschnitt 30 des zweiten Trägerelements 16 an. Entsprechend liegt der zweite Verbindungsabschnitt 28 des ersten Trägerelements 14 am vierten Verbindungsabschnitt 32 des zweiten Trägerelements 16 an. Im Bereich dieser vorzugsweise flächig aneinander anliegenden Verbindungsabschnitte 26, 30 bzw. 28, 32 sind die beiden Trägerelemente 14, 16 miteinander vorzugsweise durch Verschweißung fest verbunden.At two with respect to the body longitudinal axis L substantially diametrically opposite connecting portions 22, 24, the two support members 12, 14 are fixedly connected to each other. In these connecting regions 22, 24, the first carrier element 14 has a first connecting section 26, which extends essentially radially outward relative to the longitudinal axis L, for the first connecting region 22 and a second connecting section 28 for the second connecting region 24. In a corresponding manner, the second carrier element 16 for the first connection region 22 has a third connection section 30 extending essentially radially outward with respect to the longitudinal axis L, and a fourth connection section 32 for the second connection region 24. The first connecting portion 26 of the first support member 14 abuts the third connecting portion 30 of the second support member 16 in the assembled state. Accordingly, the second connecting portion 28 of the first support member 14 abuts the fourth connecting portion 32 of the second support member 16. In the region of these preferably flat abutting connecting portions 26, 30 and 28, 32, the two support elements 14, 16 are preferably fixedly connected to each other by welding.

Man erkennt in den Fig. 1 und 2 deutlich, dass die beiden Verbindungsbereiche 22, 24 und damit auch die Verbindungsabschnitte 26, 30 bzw. 28, 32 sich zur Körperlängsachse L nicht parallel erstrecken. Die beiden Verbindungsbereiche 22, 24 sind bezüglich einer die Trägerlängssachse L enthaltenden Referenzebene E, welche beispielsweise von den beiden Verbindungsbereichen 22, 24 in deren Längenmittenbereich durchschnitten wird, angestellt, also angewinkelt angeordnet.One recognizes in the Fig. 1 and 2 clearly that the two connecting portions 22, 24 and thus also the connecting portions 26, 30 and 28, 32 do not extend parallel to the body longitudinal axis L. With regard to a reference plane E containing the carrier longitudinal axis L, which are intersected, for example, by the two connecting regions 22, 24 in their longitudinal center region, the two connecting regions 22, 24 are arranged, that is to say they are angled.

Die beiden Verbindungsbereiche 22, 24 sind bezüglich dieser Referenzebene E gegensinnig angestellt, so dass sich aufgrund der im Wesentlichen kreisrunden Umfangskontur des Trägerkörpers 12 eine im Wesentlichen schraubenartige und gleichsinnige Erstreckung der beiden Verbindungsbereiche 22, 24 entlang des Umfangs des Trägerkörpers 12 ergibt.The two connecting regions 22, 24 are set in opposite directions with respect to this reference plane E, so that, due to the substantially circular peripheral contour of the carrier body 12, a substantially helical and co-extensive extension of the two connecting regions 22, 24 along the circumference of the carrier body 12 results.

Insbesondere aufgrund der im Wesentlichen diametral gegenüberliegenden Anordnung der beiden Verbindungsbereiche 22, 24 wird es möglich, die beiden Trägerelemente 14, 16 zueinander im Wesentlichen identisch auszugestalten. Dies führt zu vergleichsweise niedrigen Herstellungskosten. Die Schrägstellung der beiden Verbindungsbereiche 22, 24 sorgt dafür, dass im Herstellungsprozess der Abgasbehandlungsanordnung 10 beim Aufeinanderzubewegen der beiden Trägerelemente 14, 16 in einer Zusammenführbewegungsrichtung Z Fasern des das nur abschnittsweise dargestellte Abgasbehandlungselement 34 umkleidenden, allgemein auch als Lagermatte bezeichneten Fasermaterials dieses beispielsweise bereitgestellt als gewebeartiges oder vliesartiges Keramikmaterial, sich nicht im gegenseitigen Stoßbereich der Verbindungsabschnitte 26 und 30 bzw. 28 und 32 ansammeln. Vielmehr wird aufgrund der Schrägstellung der Verbindungsbereiche 22, 24 dafür gesorgt, dass die Fasern beim Aufeinanderzubewegen der Trägerelemente 14, 16 in der Zusammenführbewegungsrichtung Z nach innen gepresst werden. Manuelle Nachbearbeitungsvorgänge zum Entfernen von Fasern aus dem Stoßbereich der beiden Trägerelemente 14, 16 vor dem Verschweißen derselben können somit entfallen.In particular, due to the substantially diametrically opposite arrangement of the two connecting regions 22, 24, it becomes possible to configure the two carrier elements 14, 16 substantially identical to one another. This leads to comparatively low production costs. The oblique position of the two connecting regions 22, 24 ensures that in the manufacturing process of the exhaust treatment arrangement 10 when the two support elements 14, 16 are moved together in a direction of assembly movement Z fibers of the exhaust material treatment element 34, which is also shown in sections, generally also referred to as a bearing mat, for example, as a fabric-like material or non-woven ceramic material, do not accumulate in the mutual joint portion of the connecting portions 26 and 30 or 28 and 32. On the contrary, due to the inclination of the connecting regions 22, 24, it is ensured that the fibers are pressed inwards when the carrier elements 14, 16 are moved toward one another in the direction of the movement of the joining Z. Manual post-processing operations for removing fibers from the abutting area of the two support elements 14, 16 before welding them can thus be dispensed with.

Eine erfindungsgemäße Ausgestaltungsform einer Abgasbehandlungsanordnung wird nachfolgend mit Bezug auf die Fig. 3 bis 5 beschrieben. Komponenten, welche vorangehend beschriebenen Komponenten hinsichtlich Aufbau bzw. Funktionsweise entsprechen, sind mit dem gleichen Bezugszeichen unter Hinzufügung des Anhangs "a" bezeichnet.An embodiment of an exhaust gas treatment arrangement according to the invention will be described below with reference to FIGS Fig. 3 to 5 described. Components which correspond to the above-described components in terms of construction are denoted by the same reference numeral with the addition of the suffix "a".

Bei der in den Fig. 3 bis 5 dargestellten Ausgestaltungsform einer Abgasbehandlungsanordnung 10a ist der Trägerkörper 12a mit zwei im Wesentlichen zueinander identisch ausgestalteten, beispielsweise als Blechumformteile bereitgestellten, halbschalenartigen Trägerelementen 14a und 16a aufgebaut. Die die Verbindungsbereiche 22a bzw. 24a bereitstellenden Verbindungsabschnitte 26a, 28a, 30a und 32a verlaufen bei dieser Ausgestaltungsform im Wesentlichen parallel zur Trägerlängsachse L und liegen vorzugsweise bezüglich dieser einander diametral gegenüberliegend.In the in the Fig. 3 to 5 illustrated embodiment of an exhaust treatment system 10a, the support body 12a is constructed with two substantially identical to each other, for example, as Blechumformteile provided, half-shell-like support elements 14a and 16a. The providing the connection areas 22a and 24a Connecting portions 26a, 28a, 30a and 32a extend in this embodiment substantially parallel to the longitudinal axis L of the carrier and are preferably located diametrically opposite to each other.

Beim Zusammenbau dieser Ausgestaltungsvariante einer Abgasbehandlungsanordnung 10a wird zunächst beispielsweise das erste Trägerelement 14a so positioniert, dass dessen Verbindungsabschnitte 26a, 28a in der Zusammenführbewegungsrichtung zueinander versetzt liegen und beispielsweise einen Versatz V1 aufweisen. Vor oder nach dem Positionieren des Trägerelements 14 in derartiger Weise kann das von dem Fasermaterial 36a umgebene Abgasbehandlungselement 34a in dem Trägerelement 14a positioniert werden.When assembling this design variant of an exhaust gas treatment arrangement 10a, the first carrier element 14a is initially positioned, for example, such that its connecting sections 26a, 28a are offset from one another in the direction of the merging movement and have, for example, an offset V 1 . Before or after the positioning of the carrier element 14 in such a way, the exhaust gas treatment element 34a surrounded by the fiber material 36a can be positioned in the carrier element 14a.

Nachfolgend wird das zweite Trägerelement 16a in der Zusammenführbewegungsrichtung Z auf das erste Trägerelement 14a zu bewegt. Zumindest am Ende dieser Zusammenführbewegung ist das zweite Trägerelement 16a ebenfalls derart positioniert, dass dessen Verbindungsabschnitte 30a und 32a einen Versatz V2 in der Zusammenführbewegungsrichtung Z aufweisen, der vorzugsweise im Wesentlichen identisch ist zum Versatz V1 der beiden Verbindungsabschnitte 26a, 28a des Trägerelements 14a. Dies hat zur Folge, dass aufgrund des gleichsinnigen Versatzes bei den beiden Trägerelementen 14a, 16a die jeweils miteinander in Kontakt zu bringenden Verbindungsabschnitte 26a, 30a bzw. 28a, 32a im Verlaufe der Aufeinanderzubewegung zueinander im Wesentlichen den gleichen Abstand aufweisen, zumindest in der Endphase der Bewegung, also dann, wenn das zweite Trägerelement 16a sich über das im ersten Trägerelement 14a angeordnete Abgasbehandlungselement 34a bzw. das Fasermaterial 36a schiebt. Infolgedessen treten die den ersten Verbindungsbereich 22a bereitstellenden Verbindungsabschnitte 26a und 30a sowie die den zweiten Verbindungsbereich 24a bereitstellenden Verbindungsabschnitte 28a, 32a im Wesentlichen zeitgleich im gegenseitigen Kontakt. Nach dem Herstellen dieses Kontakts können in den beiden Verbindungsbereichen 22a, 24a die beiden Trägerelemente 14a durch Verschweißung miteinander fest und abgasdicht verbunden werden.Subsequently, the second support member 16a in the Zusammenführbewegungsrichtung Z is moved to the first support member 14a. At least at the end of this merging movement, the second carrier element 16a is likewise positioned such that its connecting sections 30a and 32a have an offset V 2 in the direction of assembly Z, which is preferably substantially identical to the offset V 1 of the two connecting sections 26a, 28a of the carrier element 14a. This has the consequence that due to the same direction offset in the two support elements 14a, 16a each to be brought into contact with each other connecting portions 26a, 30a and 28a, 32a in the course of Aufeinanderzubewegung to each other substantially the same distance, at least in the final phase of Movement, ie when the second carrier element 16a slides over the exhaust gas treatment element 34a or the fiber material 36a arranged in the first carrier element 14a. As a result, the connection portions 26a and 30a providing the first connection portion 22a and the connection portions 28a, 32a providing the second connection portion 24a substantially mutually contact each other at the same time. After producing this contact, in the two connecting regions 22a, 24a the two carrier elements 14a can be connected to one another in a fixed and exhaust gas tight manner by welding.

Auch mit der in den Fig. 3 bis 5 dargestellten Anordnung kann aufgrund des bei der Aufeinanderzubewegung der beiden Trägerelemente 14a, 16a vorhandenen Versatzes der Verbindungsabschnitte 26a, 28a bzw. 30a, 32a zueinander das Einklemmen von Fasern des Fasermaterials 36a zwischen den einander jeweils gegenüberliegenden Verbindungsabschnitten 26a, 30a bzw. 28a, 32a weitestgehend vermieden werden. Somit können Bearbeitungsvorgänge zum Pressen von Fasermaterial nach innen vermieden werden.Also with in the Fig. 3 to 5 The arrangement shown can be due to the existing in the Aufeinanderzubewegung of the two support elements 14a, 16a offset of the connecting portions 26a, 28a and 30a, 32a to each other the Clamping of fibers of the fiber material 36a between the mutually opposite connecting portions 26a, 30a and 28a, 32a are largely avoided. Thus, machining operations for pressing fiber material inward can be avoided.

Es ist abschließend darauf hinzuweisen, dass selbstverständlich die Prinzipien der vorliegenden Erfindung auch bei anderer Ausgestaltung der Abgasbehandlungsanordnung Anwendung finden können. Beispielsweise könnten in einem Trägerkörper zwei oder mehrere Abgasbehandlungselemente angeordnet sein. Der Trägerkörper könnte grundsätzlich auch eine in Richtung der Körperlängsachse L sich verjüngende Kontur bzw. eine gekrümmte Gestalt mit entsprechend gekrümmter Körperlängsachse aufweisen.Finally, it should be pointed out that, of course, the principles of the present invention can also be applied to other embodiments of the exhaust gas treatment arrangement. For example, two or more exhaust gas treatment elements could be arranged in a carrier body. The carrier body could basically also have a contour tapering in the direction of the body longitudinal axis L or a curved shape with a correspondingly curved body longitudinal axis.
