Definitions
- the present invention relates to a component of an exhaust system for an internal combustion engine, in particular a motor vehicle, having the features of the preamble of claim 1.
- the invention also relates to an exhaust system equipped with at least one such component.
- a generic exhaust system component in the form of a muffler known.
- Such a component comprises a housing which has a jacket, two end floors and at least one intermediate floor.
- the shell encloses an interior of the housing in a circumferential direction, while the two end floors define the interior at opposite ends in an axial direction and are fixedly connected to the shell.
- the intermediate floor is arranged axially between the end floors in the interior and is supported radially on the jacket.
- holders For holding an exhaust system on a periphery of the exhaust system, for example on an underbody of a motor vehicle, holders are used, which are fixedly connected at one end with a structure of the periphery of the exhaust system and the other end with a structure of the exhaust system.
- Preference is given to welded joints are used.
- said holding body may be welded to the jacket or to one of the end shelves.
- an exhaust manifold with integrated muffler in which a plurality of exhaust gas flow through exhaust manifolds are fixed via a flange on the cylinder head of an internal combustion engine and hineinerarranged into a housing of the muffler.
- the silencer housing is attached to the manifold pipes and thus also fixed to the cylinder head.
- the present invention is concerned with the problem of providing an improved embodiment for a component of the type mentioned above or for an exhaust system equipped therewith, which is characterized in particular by the fact that the possibility of a connection to a periphery of the exhaust system is improved. In particular, the risk of damage to the component during operation of the exhaust system should be reduced.
- the invention is based on the general idea, with the help of at least one holding tube on the housing to create a stop that allows a high power transmission between an attacking on the holding tube holder and the component.
- the respective holding tube is held in the interior of the housing to said intermediate floor and passed through one of the end floors and attached thereto.
- the holding tube is also sealed gas-tight, such that no exhaust gas can escape through the holding tube in the environment of the component.
- a stop is provided according to the invention with the help of the holding tube at a side facing away from the interior of the outside of said end floor, to which a holder for holding the component or the exhaust system can attack on a periphery.
- the risk of damaging the end base or the jacket is reduced, so that it is also readily possible to use reduced wall thicknesses for the realization of the jacket or of the respective end floor.
- gas-tight in the present context is to be understood as a sufficient seal against the gases typically occurring in an exhaust system, ie exhaust gas of the internal combustion engine and air.
- the respective holding tube is at least radially held or supported on the respective intermediate bottom.
- bending moments which are transmitted to the housing via a holding tube engaging on the holder, are particularly favorable supported by the holding tube on the respective end floor and on the other intermediate floor, the forces occurring due to the axial distance between the end floor and intermediate bottom are relatively small.
- a welded joint between the holder and the holding tube is largely relieved of these moments.
- an axial distance between the end base, through which the holding tube is passed, and the intermediate bottom, on which the holding tube is supported comparatively large.
- this axial distance can amount to at least 50% of a diameter of the housing.
- the distance is at least 100% of the diameter of the housing.
- the respective holding tube thus serves for fastening a holder to the housing, with which the component can be connected to the periphery of the exhaust system.
- the holding tube is gas-tight, so that it does not allow gas exchange between the interior of the housing and the environment of the component.
- the retaining tube is in any case neither an inlet tube through which exhaust gas can enter the housing, nor an outlet tube through which exhaust gas can escape from the housing.
- the end floor may have a bottom opening through which the holding tube is passed and which is enclosed by an annular collar which is gas-tight and firmly connected to the holding tube.
- an annular collar which is gas-tight and firmly connected to the holding tube.
- a welded joint can be used, for example in the form of a peripheral weld, in order to simultaneously realize the fixation and the seal.
- a solder joint or an adhesive bond can also be used here.
- the use of an annular collar, which is issued by the respective end floor, so-called “draft” or so-called “Austulpung” improves the power transmission between the holding tube and the end floor, so that larger forces can be transmitted.
- a holder for connecting the component to a periphery of the exhaust system may be attached to the holding tube on a side facing away from the interior of the outside of the respective end base.
- a holder for connecting the component to a periphery of the exhaust system may be attached to the holding tube on a side facing away from the interior of the outside of the respective end base. In this case, the holder counts to the scope of the component, which facilitates a proper fixation of the holder to the component.
- the holder may have a tubular body which is axially inserted with the holding tube and is firmly connected to the holding tube.
- the tubular body can be inserted into the holding tube. It is also conceivable arguestecken the tubular body on the holding tube.
- the holding tube may end in the area of the bottom opening.
- the tube body is slipped onto the holding tube, the holding tube projects axially beyond the end base.
- a firm connection between holding tube and tubular body can be realized particularly easily, for example via a corresponding press fit.
- a welded connection is preferred for a simplified assembly.
- a solder joint or an adhesive bond is conceivable.
- tubular body, the holding tube and the annular collar can be fastened to each other by means of a common weld seam. This makes it possible to realize the component with attached holder particularly simple and inexpensive.
- the holding tube may have a stepped cross-section, wherein the holding tube in the region of the end base has a larger cross-section than in the region of the intermediate bottom.
- the stepped one Holding tube is very easy to assemble.
- the holding tube can be inserted through the bottom opening in the housing.
- the tubular body can be inserted into the holding tube, wherein an annular step of the holding tube, which separates two regions of different cross sections, serves as an axial stop for limiting the insertion depth of the tubular body.
- the stepped construction of the holding tube thus receives an additional function, which simplifies the production of the component with holder.
- the holder may have a holding arm having a holder opening into which the holding tube is inserted, wherein the holding arm is fixed in the region of the holding opening on the holding tube.
- a welded connection a soldered connection or an adhesive connection may be considered, with a welded connection being preferred here as well.
- the holding tube protrudes axially beyond the respective end floor, so that on the outside of the holding arm can be attached to the holding tube. Nevertheless, such an arrangement is relatively compact and allows a large power transmission between the holder and housing, namely on the holding tube.
- the holding arm may be a hollow body and having two parallel walls, which are preferably fixedly connected to each other and each having a wall opening, which together form the holder opening, wherein the holding tube is fixedly connected to both walls.
- the holding arm to a sheet metal part, which is made of a single piece of sheet metal by forming.
- the support arm may also be a shell body, so be made of two or more shells.
- the support arm is made bivalve, so that two shells are provided, each having one of the walls and which may be secured to each other in a suitable manner, for example by means of welded joints.
- the walls may have passages, each forming a wall opening enclosing the associated wall opening, which improves the transmission of power between the holding tube and the wall. Also, circumferential welds can then be easier to produce.
- the holding tube may be fastened to the intermediate bottom on a side facing the respective end bottom.
- the holding tube is supported not only radially but also axially on the intermediate bottom, which improves the structural integration of the holding tube in the housing.
- the holding tube can pass through the intermediate bottom in a corresponding bottom opening and be radially supported at an opening edge.
- the holding tube penetrates the intermediate bottom. This can simplify the production, in particular when the holding tube is loosely supported on the intermediate bottom to form a sliding seat, so that relative axial movements between holding tube and intermediate bottom are possible, for example for reducing thermally induced stresses.
- the holding tube may have a closure which seals the holding tube in a gastight manner.
- the closure preferably represents a separate component with respect to the holding tube, which subsequently attached to the holding tube or installed in the holding tube. The gas-tight closing of the holding tube ensures that no gas exchange between the interior and an environment of the housing can take place through the holding tube.
- the closure can in principle be designed as a partition wall, which is inserted in the region of an axial end of the holding tube in the holding tube and is connected in a gastight manner with the holding tube.
- the partition may in principle be arranged at any position between the inner end of the holding tube and the outer end of the holding tube, wherein in addition a positioning at the inner end and a positioning at the outer end are possible. If the partition wall is arranged at one of the axial ends of the holding tube, the holding tube surrounds a cavity which is either open only to the interior or is open only to the surroundings of the housing.
- the dividing wall simultaneously divides the cavity of the holding tube into an inner section communicating with the inner space and an outer section communicating with the surroundings of the housing.
- the cavity open to the interior or the interior section open to the interior can in a preferred embodiment additionally be equipped with a gas guidance function and / or with a sound guidance function.
- the holding tube may have a perforation, whereby said cavity of the holding tube or said inner portion of the holding tube is in communication with a holding chamber surrounding the first tube.
- This first chamber may be separated, for example, by the intermediate bottom of a second chamber.
- the open inner end of the holding tube may be connected to the second space through the intermediate bottom.
- a connection between the two chambers can be made through the holding tube, for example, to allow a corresponding gas flow and / or to effect a certain sound conduction.
- the first chamber may be a resonance chamber or an absorption chamber.
- the closure is designed as a cap which is attached to an axial end of the holding tube.
- the holding tube has no gas-conducting and / or sound-conducting effect.
- the holding tube can be particularly easily integrated into existing concepts of such a component.
- the cap can be arranged on the holding tube in the region of the end tube through which the holding tube passes, so that the cavity enclosed by the holding tube is open in the interior of the housing.
- Conceivable here is a targeted tuning of the holding tube as a resonance muffler, for example in the form of a ⁇ / 2 tube or in the form of a ⁇ / 4 tube.
- the cap can be arranged in the region of the intermediate bottom on the holding tube and be firmly connected to the intermediate bottom and to the holding tube.
- the fixation of the holding tube on the false bottom is not directly, but indirectly, namely on the cap.
- this can greatly simplify the fixation of the holding tube on the intermediate bottom. It is conceivable in particular a separate production of the holding tube with cap and a later installation of this assembly consisting of holding tube and cap in the housing. Appropriately, this assembly can be tested for their gas tightness prior to their installation in the housing, resulting in a high reliability for each component.
- the fixation between the assembly and the intermediate floor can be produce particularly simple, for example by means of a welding point, which connects the intermediate bottom firmly with the cap.
- the intermediate bottom may have a complementary to the axial end face of the holding tube or complementary to the cap shaped recess, so that a recess enclosing peripheral edge allows a positive radial support of the holding tube on the intermediate bottom. At least can be effected during assembly with the help of such depression centering or positioning.
- an opening in the intermediate bottom may be formed, whereby a cavity enclosed by the holding tube is connected to a chamber of the housing, which is arranged on the intermediate bottom on a side remote from the holding tube, when the holding tube ends open in the depression.

Die vorliegende Erfindung betrifft eine Komponente einer Abgasanlage für eine Brennkraftmaschine, insbesondere eines Kraftfahrzeugs, mit den Merkmalen des Oberbegriffs des Anspruchs 1. Die Erfindung betrifft außerdem eine mit wenigstens einer derartigen Komponente ausgestattete Abgasanlage.The present invention relates to a component of an exhaust system for an internal combustion engine, in particular a motor vehicle, having the features of the preamble of

Zum Halten einer Abgasanlage an einer Peripherie der Abgasanlage, zum Beispiel an einem Unterboden eines Kraftfahrzeugs, kommen Halter zum Einsatz, die einenends mit einer Struktur der Peripherie der Abgasanlage und anderenends mit einer Struktur der Abgasanlage fest verbunden sind. Je nach Einbausituation kann es dabei auch erforderlich sein, zumindest einen solchen Halter an einer Komponente der vorstehend genannten Art zu befestigen. Hierbei ist es grundsätzlich möglich, einen entsprechenden Haltekörper des Halters am Gehäuse der Komponente zu befestigen. Bevorzugt kommen dabei Schweißverbindungen zum Einsatz. Beispielsweise kann besagter Haltekörper am Mantel oder an einem der Endböden angeschweißt sein.For holding an exhaust system on a periphery of the exhaust system, for example on an underbody of a motor vehicle, holders are used, which are fixedly connected at one end with a structure of the periphery of the exhaust system and the other end with a structure of the exhaust system. Depending on the installation situation, it may also be necessary to attach at least one such holder to a component of the aforementioned type. It is basically possible to attach a corresponding holding body of the holder on the housing of the component. Preference is given to welded joints are used. For example, said holding body may be welded to the jacket or to one of the end shelves.
Im Zuge von Gewichtseinsparungen werden bei derartigen Komponenten die Wandstärken von Blechen, mit denen der Mantel und die Endböden hergestellt werden, reduziert, wodurch die jeweilige Komponente leichter wird. Mit der reduzierten Wandstärke geht jedoch gleichzeitig eine reduzierte Stabilität einher. Im Betrieb der Abgasanlage, insbesondere in einem Fahrzeug, sind die Haltestellen, über welche die Abgasanlage an ihrer Peripherie gehalten ist, hohen Belastungen ausgesetzt. Dabei hat sich gezeigt, dass die Verbindung zwischen Haltekörper und Gehäuse einer erhöhten Beschädigungsgefahr ausgesetzt ist. Insbesondere besteht die Gefahr einer Rissbildung im Bereich der Schweißverbindung am Mantel bzw. am jeweiligen Endboden.In the course of weight savings in such components, the wall thicknesses of sheets, with which the shell and the end floors are made, reduced, whereby the respective component is easier. With the reduced wall thickness, however, accompanied at the same time a reduced stability. in the Operation of the exhaust system, especially in a vehicle, the stops, via which the exhaust system is held on its periphery, are exposed to high loads. It has been shown that the connection between the holding body and housing is exposed to increased risk of damage. In particular, there is a risk of crack formation in the region of the welded connection on the jacket or on the respective end floor.

Die vorliegende Erfindung beschäftigt sich mit dem Problem, für eine Komponente der eingangs genannten Art bzw. für eine damit ausgestattete Abgasanlage eine verbesserte Ausführungsform anzugeben, die sich insbesondere dadurch auszeichnet, dass die Möglichkeit einer Anbindung an eine Peripherie der Abgasanlage verbessert ist. Insbesondere soll die Gefahr einer Beschädigung der Komponente während des Betriebs der Abgasanlage reduziert sein.The present invention is concerned with the problem of providing an improved embodiment for a component of the type mentioned above or for an exhaust system equipped therewith, which is characterized in particular by the fact that the possibility of a connection to a periphery of the exhaust system is improved. In particular, the risk of damage to the component during operation of the exhaust system should be reduced.
Dieses Problem wird erfindungsgemäß durch den Gegenstand des unabhängigen Anspruchs gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This problem is solved according to the invention by the subject matter of the independent claim. Advantageous embodiments are the subject of the dependent claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, mit Hilfe wenigstens eines Halterohrs am Gehäuse eine Haltestelle zu schaffen, die eine hohe Kraftübertragung zwischen einem am Halterohr angreifenden Halter und der Komponente ermöglicht. Hierzu ist das jeweilige Halterohr im Innenraum des Gehäuses an besagtem Zwischenboden gehalten und durch einen der Endböden hindurchgeführt und daran befestigt. Das Halterohr ist außerdem gasdicht verschlossen, derart, dass kein Abgas durch das Halterohr in die Umgebung der Komponente austreten kann. Durch die Abstützung des Halterohrs an zwei axial voneinander beabstandeten Böden, nämlich an besagtem Endboden sowie an besagtem Zwischenboden, lassen sich über das Halterohr vergleichsweise große Kräfte auf das Gehäuse übertragen, ohne dass dabei der Zwischenboden bzw. der Endboden überlastet werden. Dementsprechend wird erfindungsgemäß mit Hilfe des Halterohrs an einer vom Innenraum abgewandten Außenseite des besagten Endbodens eine Haltestelle bereitgestellt, an welcher ein Halter zum Halten der Komponente bzw. der Abgasanlage an einer Peripherie angreifen kann. Die Gefahr einer Beschädigung des Endbodens bzw. des Mantels ist reduziert, so dass sich ohne Weiteres auch reduzierte Wandstärken zur Realisierung des Mantels bzw. des jeweiligen Endbodens verwenden lassen.The invention is based on the general idea, with the help of at least one holding tube on the housing to create a stop that allows a high power transmission between an attacking on the holding tube holder and the component. For this purpose, the respective holding tube is held in the interior of the housing to said intermediate floor and passed through one of the end floors and attached thereto. The holding tube is also sealed gas-tight, such that no exhaust gas can escape through the holding tube in the environment of the component. By supporting the holding tube on two axially spaced-apart floors, namely on said end floor and on said intermediate floor, comparatively large forces can be transmitted to the housing via the holding tube, without the intermediate floor or the end floor being overloaded. Accordingly, a stop is provided according to the invention with the help of the holding tube at a side facing away from the interior of the outside of said end floor, to which a holder for holding the component or the exhaust system can attack on a periphery. The risk of damaging the end base or the jacket is reduced, so that it is also readily possible to use reduced wall thicknesses for the realization of the jacket or of the respective end floor.
Der Begriff "gasdicht" ist im vorliegenden Zusammenhang als hinreichende Dichtung gegen die bei einer Abgasanlage typischerweise auftretenden Gase, also Abgas der Brennkraftmaschine und Luft zu verstehen.The term "gas-tight" in the present context is to be understood as a sufficient seal against the gases typically occurring in an exhaust system, ie exhaust gas of the internal combustion engine and air.
Vorzugsweise ist das jeweilige Halterohr am jeweiligen Zwischenboden zumindest radial gehalten bzw. abgestützt. Hierdurch können Biegemomente, die über einen am Halterohr angreifenden Halter auf das Gehäuse übertragen werden, vom Halterohr einerseits am jeweiligen Endboden und andererseits am jeweiligen Zwischenboden besonders günstig abgestützt werden, wobei die auftretenden Kräfte aufgrund des Axialabstands zwischen Endboden und Zwischenboden relativ klein sind. Gleichzeitig wird beispielsweise eine Schweißverbindung zwischen dem Halter und dem Halterohr von diesen Momenten weitgehend entlastet.Preferably, the respective holding tube is at least radially held or supported on the respective intermediate bottom. As a result, bending moments, which are transmitted to the housing via a holding tube engaging on the holder, are particularly favorable supported by the holding tube on the respective end floor and on the other intermediate floor, the forces occurring due to the axial distance between the end floor and intermediate bottom are relatively small. At the same time, for example, a welded joint between the holder and the holding tube is largely relieved of these moments.
Um große Momente zwischen Halterohr und Gehäuse übertragen zu können, ist ein axialer Abstand zwischen dem Endboden, durch den das Halterohr hindurchgeführt ist, und dem Zwischenboden, an dem das Halterohr abgestützt ist, vergleichsweise groß. Beispielsweise kann dieser Axialabstand mindestens 50 % eines Durchmessers des Gehäuses betragen. Bevorzugt beträgt der Abstand mindestens 100 % des Durchmessers des Gehäuses.In order to be able to transmit large moments between holding tube and housing, an axial distance between the end base, through which the holding tube is passed, and the intermediate bottom, on which the holding tube is supported, comparatively large. For example, this axial distance can amount to at least 50% of a diameter of the housing. Preferably, the distance is at least 100% of the diameter of the housing.
Das jeweilige Halterohr dient somit zum Befestigen eines Halters am Gehäuse, mit dem die Komponente mit der Peripherie der Abgasanlage verbunden werden kann. Das Halterohr ist gasdicht, sodass es keinen Gasaustausch zwischen dem Innenraum des Gehäuses und der Umgebung der Komponente ermöglicht. Somit handelt es sich beim Halterohr jedenfalls weder um ein Einlassrohr, durch das Abgas in das Gehäuse eintreten kann, noch um ein Auslassrohr, durch das Abgas aus dem Gehäuse austreten kann.The respective holding tube thus serves for fastening a holder to the housing, with which the component can be connected to the periphery of the exhaust system. The holding tube is gas-tight, so that it does not allow gas exchange between the interior of the housing and the environment of the component. Thus, the retaining tube is in any case neither an inlet tube through which exhaust gas can enter the housing, nor an outlet tube through which exhaust gas can escape from the housing.
Gemäß einer vorteilhaften Ausführungsform kann der Endboden eine Bodenöffnung aufweisen, durch die das Halterohr hindurchgeführt ist und die von einem Ringkragen eingefasst ist, der mit dem Halterohr gasdicht und fest verbunden ist. Bevorzugt kann hierbei eine Schweißverbindung zum Einsatz kommen, zum Beispiel in Form einer umlaufenden Schweißnaht, um gleichzeitig die Fixierung und die Abdichtung zu realisieren. Alternativ können hier ebenfalls eine Lötverbindung oder eine Klebverbindung zum Einsatz kommen. Die Verwendung eines Ringkragens, der vom jeweiligen Endboden ausgestellt ist, sogenannter "Durchzug" bzw. sogenannte "Austulpung", verbessert die Kraftübertragung zwischen Halterohr und Endboden, so dass größere Kräfte übertragen werden können.According to an advantageous embodiment, the end floor may have a bottom opening through which the holding tube is passed and which is enclosed by an annular collar which is gas-tight and firmly connected to the holding tube. Preferably, in this case, a welded joint can be used, for example in the form of a peripheral weld, in order to simultaneously realize the fixation and the seal. Alternatively, a solder joint or an adhesive bond can also be used here. The use of an annular collar, which is issued by the respective end floor, so-called "draft" or so-called "Austulpung" improves the power transmission between the holding tube and the end floor, so that larger forces can be transmitted.
Bei einer anderen Ausführungsform kann am Halterohr an einer vom Innenraum abgewandten Außenseite des jeweiligen Endbodens ein Halter zum Verbinden der Komponente mit einer Peripherie der Abgasanlage befestigt sein. In diesem Bei einer anderen Ausführungsform kann am Halterohr an einer vom Innenraum abgewandten Außenseite des jeweiligen Endbodens ein Halter zum Verbinden der Komponente mit einer Peripherie der Abgasanlage befestigt sein. In diesem Fall zählt der Halter zum Bauumfang der Komponente, was eine ordnungsgemäße Fixierung des Halters an der Komponente vereinfacht.In another embodiment, a holder for connecting the component to a periphery of the exhaust system may be attached to the holding tube on a side facing away from the interior of the outside of the respective end base. In this In another embodiment, a holder for connecting the component to a periphery of the exhaust system may be attached to the holding tube on a side facing away from the interior of the outside of the respective end base. In this case, the holder counts to the scope of the component, which facilitates a proper fixation of the holder to the component.
Bei einer vorteilhaften Weiterbildung kann der Halter einen Rohrkörper aufweisen, der mit dem Halterohr axial gesteckt ist und fest mit dem Halterohr verbunden ist. Hierdurch ergibt sich eine besonders einfache Montage, die über den axialen Steckbereich außerdem eine große Kraft- und Momentübertragung zwischen Rohrkörper und Halterohr ermöglicht. Der Rohrkörper kann dabei in das Halterohr eingesteckt sein. Ebenso ist denkbar, den Rohrkörper auf das Halterohr aufzustecken. Bei in das Halterohr eingestecktem Rohrkörper kann das Halterohr im Bereich der Bodenöffnung enden. Bei auf das Halterohr aufgestecktem Rohrkörper steht dagegen das Halterohr axial über den Endboden vor. Eine feste Verbindung zwischen Halterohr und Rohrkörper lässt sich besonders einfach realisieren, beispielsweise über einen entsprechenden Presssitz. Bevorzugt ist jedoch für eine vereinfachte Montage eine Schweißverbindung. Alternativ ist auch eine Lötverbindung oder eine Klebverbindung denkbar.In an advantageous development of the holder may have a tubular body which is axially inserted with the holding tube and is firmly connected to the holding tube. This results in a particularly simple assembly, which also allows a large force and torque transmission between the tubular body and holding tube on the axial plug-in area. The tubular body can be inserted into the holding tube. It is also conceivable aufzustecken the tubular body on the holding tube. When the tube body is inserted into the holding tube, the holding tube may end in the area of the bottom opening. By contrast, when the tube body is slipped onto the holding tube, the holding tube projects axially beyond the end base. A firm connection between holding tube and tubular body can be realized particularly easily, for example via a corresponding press fit. However, a welded connection is preferred for a simplified assembly. Alternatively, a solder joint or an adhesive bond is conceivable.
Bei einer anderen vorteilhaften Weiterbildung können der Rohrkörper, das Halterohr und der Ringkragen mittels einer gemeinsamen Schweißnaht aneinander befestigt sein. Hierdurch lässt sich die Komponente mit angebautem Halter besonders einfach und preiswert realisieren.In another advantageous development, the tubular body, the holding tube and the annular collar can be fastened to each other by means of a common weld seam. This makes it possible to realize the component with attached holder particularly simple and inexpensive.
Gemäß einer anderen vorteilhaften Ausführungsform kann das Halterohr einen gestuften Querschnitt aufweisen, wobei das Halterohr im Bereich des Endbodens einen größeren Querschnitt besitzt als im Bereich des Zwischenbodens. Das gestufte Halterohr lässt sich besonders einfach Montieren. Beispielsweise kann das Halterohr durch die Bodenöffnung in das Gehäuse eingesetzt werden.According to another advantageous embodiment, the holding tube may have a stepped cross-section, wherein the holding tube in the region of the end base has a larger cross-section than in the region of the intermediate bottom. The stepped one Holding tube is very easy to assemble. For example, the holding tube can be inserted through the bottom opening in the housing.
Bei einer anderen vorteilhaften Weiterbildung kann der Rohrkörper in das Halterohr eingesteckt sein, wobei eine Ringstufe des Halterohrs, die zwei Bereiche unterschiedlicher Querschnitte voneinander trennt, als Axialanschlag zur Begrenzung der Einstecktiefe des Rohrkörpers dient. Die gestufte Bauweise des Halterohrs erhält dadurch eine Zusatzfunktion, welche die Herstellung der Komponente mit Halter vereinfacht.In another advantageous development, the tubular body can be inserted into the holding tube, wherein an annular step of the holding tube, which separates two regions of different cross sections, serves as an axial stop for limiting the insertion depth of the tubular body. The stepped construction of the holding tube thus receives an additional function, which simplifies the production of the component with holder.
Bei einer anderen Ausführungsform kann der Halter einen Haltearm aufweisen, der eine Halteröffnung besitzt, in die das Halterohr eingesteckt ist, wobei der Haltearm im Bereich der Halteöffnung am Halterohr befestigt ist. Als geeignete Befestigungsmethoden kommen auch hier wieder eine Schweißverbindung, eine Lötverbindung oder eine Klebverbindung in Betracht, wobei auch hier eine Schweißverbindung bevorzugt wird. Bei dieser Bauform ragt das Halterohr axial über den jeweiligen Endboden vor, so dass an dessen Außenseite der Haltearm auf das Halterohr aufgesteckt werden kann. Dennoch baut eine derartige Anordnung vergleichsweise kompakt und ermöglicht eine große Kraftübertragung zwischen Halter und Gehäuse, nämlich über das Halterohr.In another embodiment, the holder may have a holding arm having a holder opening into which the holding tube is inserted, wherein the holding arm is fixed in the region of the holding opening on the holding tube. Again, as a suitable fastening methods, a welded connection, a soldered connection or an adhesive connection may be considered, with a welded connection being preferred here as well. In this design, the holding tube protrudes axially beyond the respective end floor, so that on the outside of the holding arm can be attached to the holding tube. Nevertheless, such an arrangement is relatively compact and allows a large power transmission between the holder and housing, namely on the holding tube.
Bei einer vorteilhaften Weiterbildung kann der Haltearm ein Hohlkörper sein und zwei parallel verlaufende Wände aufweisen, die vorzugsweise fest miteinander verbunden sind und die jeweils eine Wandöffnung aufweisen, die gemeinsam die Halteröffnung bilden, wobei das Halterohr mit beiden Wänden fest verbunden ist. Hierdurch ergibt sich für den Halter eine besonders leichte und preiswert realisierbare Bauform, wobei dennoch hohe Kräfte übertragen werden können.In an advantageous development of the holding arm may be a hollow body and having two parallel walls, which are preferably fixedly connected to each other and each having a wall opening, which together form the holder opening, wherein the holding tube is fixedly connected to both walls. This results in a particularly easy and inexpensive realizable design for the holder, yet high forces can be transmitted.
Beispielsweise handelt es sich beim Haltearm um ein Blechformteil, das aus einem einzigen Blechstück durch Umformung hergestellt ist. Alternativ dazu kann der Haltearm auch ein Schalenkörper sein, also aus zwei oder mehr Schalen hergestellt sein. Bevorzugt ist der Haltearm zweischalig hergestellt, so dass zwei Schalen vorgesehen sind, die jeweils eine der Wände aufweisen und die auf geeignete Weise aneinander befestigt sein können, beispielsweise mittels Schweißverbindungen.For example, it is the holding arm to a sheet metal part, which is made of a single piece of sheet metal by forming. Alternatively, the support arm may also be a shell body, so be made of two or more shells. Preferably, the support arm is made bivalve, so that two shells are provided, each having one of the walls and which may be secured to each other in a suitable manner, for example by means of welded joints.
Die Wände können Durchzüge aufweisen, die jeweils eine die zugehörige Wandöffnung einfassenden Ringkragen bilden, was die Kraftübertragung zwischen Halterohr und Wand verbessert. Auch lassen sich umlaufende Schweißnähte dann einfacher herstellen.The walls may have passages, each forming a wall opening enclosing the associated wall opening, which improves the transmission of power between the holding tube and the wall. Also, circumferential welds can then be easier to produce.
Bei einer anderen Ausführungsform kann das Halterohr an einer dem jeweiligen Endboden zugewandten Seite am Zwischenboden befestigt sein. Hierdurch ist das Halterohr nicht nur radial, sondern auch axial am Zwischenboden abgestützt, was die strukturelle Integration des Halterohrs in das Gehäuse verbessert.In another embodiment, the holding tube may be fastened to the intermediate bottom on a side facing the respective end bottom. As a result, the holding tube is supported not only radially but also axially on the intermediate bottom, which improves the structural integration of the holding tube in the housing.
Bei einer alternativen Bauform kann das Halterohr den Zwischenboden in einer entsprechenden Bodenöffnung durchsetzen und an einem Öffnungsrand radial abgestützt sein. Bei dieser Bauform durchdringt das Halterohr den Zwischenboden. Dies kann die Herstellung vereinfachen, insbesondere dann, wenn das Halterohr am Zwischenboden zur Ausbildung eines Schiebesitzes lose abgestützt ist, so dass axial Relativbewegungen zwischen Halterohr und Zwischenboden möglich sind, beispielsweise zur Reduzierung thermisch bedingter Spannungen.In an alternative design, the holding tube can pass through the intermediate bottom in a corresponding bottom opening and be radially supported at an opening edge. In this design, the holding tube penetrates the intermediate bottom. This can simplify the production, in particular when the holding tube is loosely supported on the intermediate bottom to form a sliding seat, so that relative axial movements between holding tube and intermediate bottom are possible, for example for reducing thermally induced stresses.
Gemäß einer anderen Ausführungsform kann das Halterohr einen Verschluss aufweisen, der das Halterohr gasdicht verschließt. Der Verschluss repräsentiert dabei bevorzugt ein bezüglich des Halterohrs separates Bauteil, der nachträglich an das Halterohr angebaut bzw. in das Halterohr eingebaut ist. Durch das gasdichte Verschließen des Halterohrs wird erreicht, dass durch das Halterohr hindurch kein Gasaustausch zwischen dem Innenraum und einer Umgebung des Gehäuses erfolgen kann.According to another embodiment, the holding tube may have a closure which seals the holding tube in a gastight manner. In this case, the closure preferably represents a separate component with respect to the holding tube, which subsequently attached to the holding tube or installed in the holding tube. The gas-tight closing of the holding tube ensures that no gas exchange between the interior and an environment of the housing can take place through the holding tube.
Der Verschluss kann dabei grundsätzlich als Trennwand ausgestaltet sein, die im Bereich eines axialen Endes des Halterohrs in das Halterohr eingesetzt ist und gasdicht mit dem Halterohr verbunden ist. Die Trennwand kann dabei grundsätzlich an jeder beliebigen Position zwischen dem innenliegenden Ende des Halterohrs und dem außenliegenden Ende des Halterohrs angeordnet sein, wobei außerdem eine Positionierung am innenliegenden Ende sowie eine Positionierung am außenliegenden Ende möglich sind. Sofern die Trennwand an einem der axialen Enden des Halterohrs angeordnet ist, umschließt das Halterohr einen Hohlraum, der entweder nur zum Innenraum offen ist oder nur zur Umgebung des Gehäuses offen ist. Ist die Trennwand dagegen axial zwischen den axialen Enden des Halterohrs angeordnet, bewirkt die Trennwand gleichzeitig eine Unterteilung des Hohlraums des Halterohrs in einen mit dem Innenraum kommunizierenden Innenabschnitt und einen mit der Umgebung des Gehäuses kommunizierenden Außenabschnitt. Der zum Innenraum offene Hohlraum bzw. der zum Innenraum offene Innenabschnitt kann bei einer bevorzugten Ausführungsform zusätzlich mit einer Gasführungsfunktion und/oder mit einer Schallführungsfunktion ausgestattet sein. Beispielsweise kann das Halterohr eine Perforation aufweisen, wodurch besagter Hohlraum des Halterohrs bzw. besagter Innenabschnitt des Halterohrs mit einer das Halterohr umhüllenden ersten Kammer in Verbindung steht. Diese erste Kammer kann beispielsweise durch den Zwischenboden von einer zweiten Kammer getrennt sein. Das offene innere Ende des Halterohrs kann durch den Zwischenboden hindurch mit dem zweiten Raum verbunden sein. Somit kann durch das Halterohr hindurch eine Verbindung zwischen den beiden Kammern hergestellt werden, beispielsweise um eine entsprechende Gasströmung zu ermöglichen und/oder um eine bestimmte Schallführung zu bewirken. Beispielsweise kann die erste Kammer eine Resonanzkammer oder eine Absorptionskammer sein.The closure can in principle be designed as a partition wall, which is inserted in the region of an axial end of the holding tube in the holding tube and is connected in a gastight manner with the holding tube. The partition may in principle be arranged at any position between the inner end of the holding tube and the outer end of the holding tube, wherein in addition a positioning at the inner end and a positioning at the outer end are possible. If the partition wall is arranged at one of the axial ends of the holding tube, the holding tube surrounds a cavity which is either open only to the interior or is open only to the surroundings of the housing. On the other hand, if the dividing wall is arranged axially between the axial ends of the holding tube, the dividing wall simultaneously divides the cavity of the holding tube into an inner section communicating with the inner space and an outer section communicating with the surroundings of the housing. The cavity open to the interior or the interior section open to the interior can in a preferred embodiment additionally be equipped with a gas guidance function and / or with a sound guidance function. For example, the holding tube may have a perforation, whereby said cavity of the holding tube or said inner portion of the holding tube is in communication with a holding chamber surrounding the first tube. This first chamber may be separated, for example, by the intermediate bottom of a second chamber. The open inner end of the holding tube may be connected to the second space through the intermediate bottom. Thus, a connection between the two chambers can be made through the holding tube, for example, to allow a corresponding gas flow and / or to effect a certain sound conduction. For example, the first chamber may be a resonance chamber or an absorption chamber.
Bevorzugt ist jedoch eine Ausführungsform, bei welcher der Verschluss als Kappe ausgestaltet ist, die auf ein axiales Ende des Halterohrs aufgesteckt ist. Hierdurch ergibt sich eine besonders einfache Herstellbarkeit für das gasdicht verschlossene Halterohr. Ferner ist eine Ausführungsform bevorzugt, bei welcher das Halterohr keinerlei gasführende und/oder schallführende Wirkung aufweist. In diesem Fall lässt sich das Halterohr besonders einfach in bestehende Konzepte einer derartigen Komponente integrieren.However, preferred is an embodiment in which the closure is designed as a cap which is attached to an axial end of the holding tube. This results in a particularly simple manufacturability for the gas-tight closed holding tube. Furthermore, an embodiment is preferred in which the holding tube has no gas-conducting and / or sound-conducting effect. In this case, the holding tube can be particularly easily integrated into existing concepts of such a component.
Beispielsweise kann die Kappe im Bereich des vom Halterohr durchsetzten Endbodens am Halterohr angeordnet sein, sodass der vom Halterohr umschlossene Hohlraum im Innenraum des Gehäuses offen ist. Denkbar ist dabei eine gezielte Abstimmung des Halterohrs als Resonanzschalldämpfer, beispielsweise in Form eines λ/2-Rohrs oder in Form eines λ/4-Rohrs.For example, the cap can be arranged on the holding tube in the region of the end tube through which the holding tube passes, so that the cavity enclosed by the holding tube is open in the interior of the housing. Conceivable here is a targeted tuning of the holding tube as a resonance muffler, for example in the form of a λ / 2 tube or in the form of a λ / 4 tube.
Gemäß einer anderen vorteilhaften Weiterbildung kann die Kappe im Bereich des Zwischenbodens am Halterohr angeordnet sein und mit dem Zwischenboden sowie mit dem Halterohr fest verbunden sein. Bei dieser Bauform erfolgt die Fixierung des Halterohrs am Zwischenboden nicht direkt, sondern indirekt, nämlich über die Kappe. Insbesondere lässt sich dadurch die Fixierung des Halterohrs am Zwischenboden erheblich vereinfachen. Denkbar ist insbesondere eine separate Herstellung des Halterohrs mit Kappe und ein späterer Einbau dieser Baugruppe bestehend aus Halterohr und Kappe in das Gehäuse. Zweckmäßig kann diese Baugruppe vor ihrem Einbau in das Gehäuse auf ihre Gasdichtigkeit geprüft werden, wodurch sich eine hohe Funktionssicherheit für die jeweilige Komponente ergibt. Die Fixierung zwischen der Baugruppe und dem Zwischenboden lässt sich besonders einfach beispielsweise mittels eines Schweißpunkts erzeugen, der den Zwischenboden fest mit der Kappe verbindet.According to another advantageous development, the cap can be arranged in the region of the intermediate bottom on the holding tube and be firmly connected to the intermediate bottom and to the holding tube. In this design, the fixation of the holding tube on the false bottom is not directly, but indirectly, namely on the cap. In particular, this can greatly simplify the fixation of the holding tube on the intermediate bottom. It is conceivable in particular a separate production of the holding tube with cap and a later installation of this assembly consisting of holding tube and cap in the housing. Appropriately, this assembly can be tested for their gas tightness prior to their installation in the housing, resulting in a high reliability for each component. The fixation between the assembly and the intermediate floor can be produce particularly simple, for example by means of a welding point, which connects the intermediate bottom firmly with the cap.
Des Weiteren ist ein Formschluss in radialer Richtung zwischen Zwischenboden und Halterohr oder zwischen Zwischenboden und Kappe denkbar. Beispielsweise kann der Zwischenboden hierzu eine komplementär zur axialen Stirnseite des Halterohrs oder komplementär zur Kappe geformte Vertiefung aufweisen, so dass ein die Vertiefung einfassender umlaufender Rand eine formschlüssige radiale Abstützung des Halterohrs am Zwischenboden ermöglicht. Zumindest kann mit Hilfe einer derartigen Vertiefung eine Zentrierung bzw. Positionierung während der Montage bewirkt werden. Im Bereich dieser Vertiefung kann eine Öffnung im Zwischenboden ausgebildet sein, wodurch ein vom Halterohr umschlossener Hohlraum mit einer Kammer des Gehäuses, die am Zwischenboden an einer vom Halterohr abgewandten Seite angeordnet ist, verbunden ist, wenn das Halterohr in der Vertiefung offen endet.Furthermore, a positive connection in the radial direction between the intermediate floor and holding tube or between the intermediate bottom and cap is conceivable. For example, the intermediate bottom may have a complementary to the axial end face of the holding tube or complementary to the cap shaped recess, so that a recess enclosing peripheral edge allows a positive radial support of the holding tube on the intermediate bottom. At least can be effected during assembly with the help of such depression centering or positioning. In the region of this depression, an opening in the intermediate bottom may be formed, whereby a cavity enclosed by the holding tube is connected to a chamber of the housing, which is arranged on the intermediate bottom on a side remote from the holding tube, when the holding tube ends open in the depression.
Bei dieser Komponente handelt es sich bevorzugt um einen Schalldämpfer. Alternativ kann es sich bei der Komponente auch um einen Katalysator oder um ein Partikelfilter handeln. Grundsätzlich sind auch kombinierte Komponenten denkbar, wenn in einem gemeinsamen Gehäuse zumindest zwei Mitglieder aus der Gruppe Schalldämpfer, Katalysator und Partikelfilter angeordnet sind.This component is preferably a silencer. Alternatively, the component may also be a catalyst or a particulate filter. In principle, combined components are also conceivable if at least two members from the group consisting of muffler, catalytic converter and particle filter are arranged in a common housing.
Eine erfindungsgemäße Abgasanlage umfasst zumindest einen Abgasstrang, der eintrittsseitig wenigstens einen Abgaskrümmer und austrittsseitig wenigstens ein Endrohr aufweist.
