Description
Die Erfindung bezieht sich auf einen Schalldämpfer für eine Abgasanlage eines Kraftfahrzeuges mit einem integrierten Katalysator, wobei der Abgasstrom über Rohrleitungen in einem den Katalysator haltenden Behälter eingeleitet werden, der in mehrere Kammern geteilt ist.The invention relates to a silencer for an exhaust system of a motor vehicle with an integrated catalyst, wherein the exhaust gas flow is introduced via pipes into a container holding the catalyst, which is divided into several chambers.
Bei Schalldämpfern üblicher Bauart werden die Katalysatoren in Öffnungen von
Querwandteilen angeordnet und festgesetzt.
10In conventional silencers, the catalysts are arranged and fixed in openings of transverse wall parts.

Aufgabe der Erfindung ist es, einen Schalldämpfer mit einem Katalysator zu schaffen, der in einfacher Weise an der Längswand des Schalldämpfers festgesetzt ist.The object of the invention is to provide a silencer with a catalyst which is attached in a simple manner to the longitudinal wall of the silencer.
Die Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Merkmale beinhalten die Unteransprüche.The object is achieved according to the invention by the characterizing features of claim 1. Further advantageous features are contained in the subclaims.
Die mit der Erfindung hauptsächlich erzielten Vorteile bestehen darin, daß in eine den Innenraum des Schalldämpfers unterteilende Längswand der Katalysator eingebettet angeordnet ist. Hierzu ist die Längswand im Bereich des Durchtritts des Katalysators geschlitzt ausgeführt und die Schlitzkanten werden so weit zur Aufnahme des Katalysators auseinandergezogen, bis sich die Schlitzkanten an die Umfangskontur des Katalysators anlegen können. Hiernach erfolgt über eine Verbindung z.B. Löten, Schweißen und dgl. ein Festsetzen des Katalysators in der Öffnung der Längswand.The main advantages achieved with the invention are that the catalyst is embedded in a longitudinal wall that divides the interior of the muffler. For this purpose, the longitudinal wall is slotted in the area where the catalyst passes through and the slot edges are pulled apart to accommodate the catalyst until the slot edges can be placed against the peripheral contour of the catalyst. The catalyst is then fixed in the opening of the longitudinal wall by means of a connection, e.g. soldering, welding, etc.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird
im folgenden näher beschrieben.
Es zeigenAn embodiment of the invention is shown in the drawing and is described in more detail below.

Fig. 3 eine Draufsicht auf eine Längswand mit Querschlitz und Fig. 4 einen Schnitt nach der Linie IV-IV der Fig. 1.Fig. 3 is a plan view of a longitudinal wall with a transverse slot and Fig. 4 is a section along the line IV-IV of Fig. 1.
Ein Schalldämpfer 1 einer Abgasanlage umfasst im wesentlichen einen Behälter 2, bestehend aus zwei Schalen 3 und 4, die mit einer den Innenraum 5 des Behälters 2 trennende Längswand 6 miteinander verbunden sind. In der Längswand 6 ist ein Katalysator 7 gehalten, durch den die vom Motor kommenden Abgase nach außen hin in die Atmosphäre abgeführt werden.A silencer 1 of an exhaust system essentially comprises a container 2 consisting of two shells 3 and 4, which are connected to one another by a longitudinal wall 6 separating the interior 5 of the container 2. A catalyst 7 is held in the longitudinal wall 6, through which the exhaust gases coming from the engine are discharged outwards into the atmosphere.
Die Längswand 6 besteht aus einem Blech 8 (Fig. 3) und weist einen Querschiitz 9 auf. Durch ein Aufweiten des Schützes 9 bis auf den Durchmesser D des Katalysators 7 wird die Möglichkeit des Durchsteckens geschaffen, wie Fig. 4 näher zeigt.The longitudinal wall 6 consists of a sheet metal 8 (Fig. 3) and has a transverse cutout 9. By widening the cutout 9 to the diameter D of the catalyst 7, the possibility of passing through is created, as Fig. 4 shows in more detail.
Die Schlitzkanten 10 und 11 der Längswand 6 werden um die runde Außenkontur des Katalysators 7 geformt, so daß sie anliegend sind. Danach erfolgt eine Verbindung der Blechkanten 10 und 11 mit der Außenkontur des Katalysators 7.The slot edges 10 and 11 of the longitudinal wall 6 are formed around the round outer contour of the catalyst 7 so that they are flush. The sheet edges 10 and 11 are then connected to the outer contour of the catalyst 7.
