Aufgabe der Erfindung ist es, ein einfaches und kostengünstiges Verfahren zur Herstellung eines Fahrzeugschalldämpfers, bei dem sich mindestens ein Rohr durch die Umfangswand ins Schalldämpferinnere erstreckt, in gewickelter Bauweise sowie einen derartigen, kostengünstigen Schalldämpfer zu schaffen.The object of the invention is to provide a simple and cost-effective method for producing a vehicle silencer, in which at least one tube extends through the peripheral wall into the silencer interior, in wound construction and such a cost-effective silencer.
Dies wird durch ein Verfahren zur Herstellung eines Fahrzeugschalldämpfers mit den Merkmalen des Anspruchs 1 erreicht. Das erfindungsgemäße Verfahren zur Herstellung eines eingangs genannten Fahrzeugschalldämpfers umfasst die Verfahrensschritte, dass ein Endrohr durch eine Aussparung im Wickelmantel auf oder in ein Stützblech des Schalldämpfereinsatzes oder ein mit dem Stützblech verbundenes Innenrohr zur Schaffung einer Steckverbindung gesteckt wird. Das Endrohr wird auf einen Stutzen des Stützblechs gesteckt. Alternativ hierzu wird das Endrohr in eine Öffnung des Stützblechs gesteckt, wobei dabei das freie Ende des Endrohres wenigstens in Richtung aus dem Gehäuse heraus zum Stützblech axial beweglich ist. Das Endrohr wird also zuerst radial in der Ebene des Stützblechs positioniert und anschließend unter Aufrechterhaltung der erzeugten Steckverbindung am Wickelmantel befestigt. Das Zusammenwirken der Steckverbindung von Endrohr und Schalldämpfereinsatz mit der Befestigung des Endrohres am Wickelmantel ermöglicht eine ausreichende Verbindung des Endrohres mit dem Fahrzeugschalldämpfer, ohne dass eine zusätzliche aufwendige Bearbeitung des Endrohres nötig ist. Im Bereich der Steckverbindung erfolgt keine weitere Bearbeitung/Verbindung der Teile. Auf diese Weise ist die Herstellung des Fahrzeugschalldämpfers einfach und kostengünstig. Ein weiterer Vorteil liegt in der Ausgestaltung der Steckverbindung, die sehr einfach realisierbar ist und gewisse Freiheitsgrade einer Relativbewegung des Rohres und des Schalldämpfereinsatzes erlauben oder einschränken kann, wodurch mögliche mechanische Spannungen, beispielsweise bei Temperaturunterschieden im Fahrzeugschalldämpfer vermieden werden können. Da es nicht nötig ist, ein Werkzeug ins Innere des Endrohrs einzuführen, können beliebig lange und beliebig geformte Rohre als Endrohre verwendet werden. Es können insbesondere direkt die Rohre eines Abgassystems mit dem Fahrzeugschalldämpfer verbunden werden. Es ist möglich, dass das Endrohr am Rohrende eine Verjüngung, vorzugsweise eine konische Verjüngung, aufweist, wobei das Endrohr mit der Verjüngung in die Öffnung des Stützbleches gesteckt wird. Auf diese Weise kann einerseits die Positionierung des Endrohres erleichtert werden, und andererseits wird auf einfache Weise ein Toleranzausgleich zwischen dem Rohrdurchmesser und dem Durchmesser der Öffnung des Stützbleches ermöglicht.This is achieved by a method for producing a vehicle silencer with the features of claim 1. The inventive method for producing a vehicle muffler mentioned above comprises the method steps that a tail pipe is inserted through a recess in the winding shell on or in a support plate of the muffler insert or connected to the support plate inner tube to create a connector. The tailpipe is placed on a socket of the support plate. Alternatively, the tail pipe is inserted into an opening of the support plate, in which case the free end of the tail pipe is axially movable at least in the direction out of the housing to the support plate. The tailpipe is thus first positioned radially in the plane of the support plate and then secured while maintaining the connector produced on the winding jacket. The interaction of the connector of the tailpipe and muffler insert with the attachment of the tailpipe to the winding jacket allows a sufficient connection of the tailpipe with the vehicle muffler without an additional complex processing of the tailpipe is necessary. In the area of the connector no further processing / connection of the parts takes place. In this way, the production of the vehicle muffler is simple and inexpensive. Another advantage lies in the design of the connector, which is very easy to implement and certain degrees of relative movement of the pipe and the muffler insert allow or limit, thereby possible mechanical stresses, for example, can be avoided in temperature differences in the vehicle muffler. Since it is not necessary to introduce a tool inside the tailpipe, any length and arbitrarily shaped tubes can be used as tailpipes. In particular, the pipes of an exhaust system can be connected directly to the vehicle silencer. It is possible for the tailpipe to have a taper at the pipe end, preferably a conical taper, with the tailpipe being inserted with the taper into the opening of the support plate. In this way, on the one hand, the positioning of the tailpipe be facilitated, and on the other hand, a tolerance compensation between the pipe diameter and the diameter of the opening of the support plate is made possible in a simple manner.
Es ist auch möglich, dass das Endrohr am Rohrende eine Aufweitung, vorzugsweise eine konische Aufweitung, aufweist.It is also possible that the tailpipe has a widening, preferably a conical widening, at the pipe end.
Das Stützblech kann eine Öffnung aufweisen, in deren Randbereich das Stützblech einen zumindest teilweise in Richtung zur Aussparung des Wickelmantels erstreckenden Stutzen hat, wobei das Endrohr auf oder in den Stutzen gesteckt wird.The support plate may have an opening, in the edge region of the support plate has an at least partially extending in the direction of the recess of the winding jacket nozzle, wherein the tail pipe is placed on or in the nozzle.
Es ist möglich, dass der Stutzen eine, vorzugsweise konische, Verjüngung in Richtung zur Aussparung des Wickelmantels aufweist, was ebenfalls der spielfreien radialen Fixierung des freien Endes des Endrohres dient.It is possible that the neck has a, preferably conical, taper in the direction of the recess of the winding jacket, which also serves the play-free radial fixation of the free end of the tailpipe.
Der Schalldämpfereinsatz kann ein Innenrohr aufweisen, welches durch die Öffnung des Stützbleches ragt und mit dem Stützblech verbunden ist, wobei das Innenrohr den zumindest teilweise in Richtung zur Aussparung des Wickelmantels erstreckenden Stutzen bildet. Auf diese Weise können die Endrohre direkt mit Innenrohren des Fahrzeugschalldämpfers verbunden werden, wodurch unterschiedliche Rohrlängen zur Beeinflussung der akustischen Eigenschaften des Fahrzeugschalldämpfers ermöglicht werden.The muffler insert may have an inner tube which projects through the opening of the support plate and is connected to the support plate, wherein the inner tube forms the at least partially extending in the direction of the recess of the winding mantle. In this way, the tailpipes can be connected directly to inner tubes of the vehicle silencer, whereby different tube lengths are made possible to influence the acoustic properties of the vehicle silencer.
Gemäß einer weiteren Verfahrensvariante entspricht der Stutzen im Wesentlichen dem Innenradius des Endrohrs, so dass die Steckverbindung einen axialen Schiebesitz bildet. Auf diese Weise ist das freie Ende des Endrohres axial beweglich.According to a further variant of the method, the nozzle substantially corresponds to the inner radius of the tail pipe, so that the plug connection forms an axial sliding seat. In this way, the free end of the tail pipe is axially movable.
Das Stützblech kann beim Einstecken des Endrohrs einen Anschlag für das Endrohr bilden, so dass Stützblech eine Bewegung des Endrohrs in axialer Richtung begrenzt. Auf diese Weise bildet das Stützblech einen Anschlag beim Einstecken des Endrohrs und ermöglicht somit eine axiale Positionierung des Endrohres am Schälldämpfereinsatz. Dies ist insbesondere bei einem konisch geformten Teil leicht realisierbar.The support plate can form a stop for the tailpipe upon insertion of the tailpipe, so that the support plate limits movement of the tailpipe in the axial direction. In this way, the support plate forms a stop when inserting the tailpipe and thus enables an axial positioning of the tailpipe on Schälldämpfereinsatz. This is easy to realize, especially with a conically shaped part.
Gemäß einer bevorzugten Verfahrensvariante wird das Endrohr am Wickelmantel durch Schweißen befestigt.According to a preferred variant of the method, the tailpipe is fastened to the winding jacket by welding.
Es ist möglich, dass das Endrohr einen Kragen aufweist und das Endrohr über den Kragen am Wickelmantel befestigt wird. Auf diese Weise können Fertigungstoleranzen zwischen dem Außenquerschnitt des Endrohrs und der Aussparung des Wickelmantels, durch welche das Endrohr gesteckt wird, auf einfache Weise ausgeglichen werden.It is possible that the tailpipe has a collar and the tailpipe is fastened via the collar to the winding jacket. In this way, manufacturing tolerances between the outer cross section of the end tube and the recess of the winding jacket, through which the tail pipe is inserted, can be compensated in a simple manner.
Die Erfindung betrifft darüber hinaus einen Fahrzeugschalldämpfer, welcher nach einem oben beschriebenen Verfahren hergestellt ist, mit einem Gehäuse, welches entgegengesetzte äußere Stirnwände und einen durch Wickeln eines Blechteils gebildeten Wickelmantel umfasst, wenigstens einem Schalldämpfereinsatz und wenigstens einem Endrohr. Das Endrohr erstreckt sich durch den Wickelmantel ins Schalldämpferinnere, wobei das Endrohr am Wickelmantel befestigt ist und durch eine Steckverbindung mit einem Stützblech des Schalldämpfereinsatzes verbunden ist. Das Endrohr ist auf einen Stutzen des Stützblechs oder in eine Öffnung des Stützblechs gesteckt, wobei das freie Ende des Endrohres wenigstens in Richtung aus dem Gehäuse heraus zum Stützblech axial beweglich ist. Wie bereits beschrieben ist ein derartiger Fahrzeugschalldämpfer einfach und kostengünstig herzustellen.The invention further relates to a vehicle silencer, which is produced by a method described above, with a housing which comprises opposite outer end walls and a winding jacket formed by winding a sheet metal part, at least one silencer insert and at least one tail pipe. The tailpipe extends through the winding jacket into the silencer interior, wherein the tailpipe is attached to the winding jacket and is connected by a plug connection with a support plate of the silencer insert.

As already described, such a vehicle silencer is simple and inexpensive to manufacture.
Vorzugsweise ist das freie Ende des Endrohres wenigstens in Richtung aus dem Gehäuse heraus zum Stützblech axial beweglich. Auf diese Weise werden mechanische Spannungen, beispielsweise aufgrund von thermischen Ausdehnungen, im Fahrzeugschalldämpfer reduziert.Preferably, the free end of the tail pipe is axially movable at least in the direction out of the housing to the support plate. In this way, mechanical stresses, for example due to thermal expansion, reduced in the vehicle muffler.
