Abstract
Description
Die Erfindung betrifft eine Partikelfilteranordnung zur Anordnung in einem Abgasströmungsweg eines brennkraftmaschinengetriebenes Kraftfahrzeugs, wobei die Partikelfilteranordnung ein Gehäuse mit einer Abgaseintrittsöffnung und einer Abgasaustrittsöffnung sowie einen Filterkörper aufweist, der aus einer Mehrzahl quaderförmiger Segmente zusammengesetzt ist.The invention relates to a particulate filter arrangement for arrangement in an exhaust gas flow path of an internal combustion engine-driven motor vehicle, wherein the particulate filter assembly comprises a housing having an exhaust gas inlet opening and an exhaust gas outlet opening and a filter body which is composed of a plurality of cuboidal segments.
Derartige Partikelfilter dienen zur Entfernung von Ruß- und sonstigen Partikeln aus dem Abgas von insbesondere dieselbetriebenen Brennkraftmaschinen und umfassen üblicherweise ein Gehäuse mit einem darin abgasdurchströmbar angeordneten Filterkörper, der einen runden oder elliptischen Querschnitt aufweist. Ein Partikelfilter mit einem runden Filterkörper geht beispielsweise aus der
Zur Herstellung der bekannten Filterkörper wird eine Mehrzahl quaderförmiger Filtersegmente miteinander verbunden und dann die erforderliche Außenkontur durch in der Regel spanende Bearbeitung hergestellt. Bedingt durch die Quaderform der miteinander zum Filterkörper verbundenen Filtersegmente ergibt sich ein wiederum quaderförmiger Filterkörper, sodass viel Abfall entsteht. Außerdem steht aufgrund der runden oder elliptischen Querschnittsform des Filterkörpers ein reduzierter Filterquerschnitt zur Abgasreinigung zur Verfügung.To produce the known filter body a plurality of cuboid filter segments is connected to each other and then the required outer contour produced by machining usually machining. Due to the cuboid shape of the filter segments connected to each other filter body results in turn a cuboid filter body, so much waste produced. In addition, due to the round or elliptical cross-sectional shape of the filter body, a reduced filter cross-section for exhaust gas purification is available.
Aufgabe der Erfindung ist es daher, eine eingangs genannte Partikelfilteranordnung bereit zu stellen, die eine bessere Ausnutzung des Filterköpermaterials ermöglicht und die einen vergrößerten Filterquerschnitt zur Abgasreinigung aufweist.The object of the invention is therefore to provide a particulate filter arrangement mentioned above, which allows better utilization of the filter body material and which has an enlarged filter cross-section for exhaust gas purification.
Die Lösung der Aufgabe erfolgt mit einer Partikelfilteranordnung mit den Merkmalen des Anspruchs 1, indem der im Gehäuse angeordnete Filterkörper seinerseits eine zumindest quaderähnliche Form aufweist. Damit muss bei der Fertigstellung des Filterkörpers aus einem quaderförmigen, aus einer Mehrzahl ihrerseits quaderförmiger Filtersegmente bestehenden Filterkörper weniger Filtermaterial abgetragen werden, sodass das Filtermaterial besser ausgenutzt werden kann und weniger Abfall entsteht. Die zur Verfügung stehenden Filtersegmente werden so bestmöglich ausgenutzt. Außerdem ermöglicht ein erfindungsgemäß ausgeformtes Filterelement aufgrund seiner bauraumgünstigen Form eine Verwendung als Gleichteil für viele unterschiedliche Fahrzeugtypen.The object is achieved with a particle filter assembly having the features of claim 1, in that the filter body arranged in the housing in turn has an at least parallelepiped-like shape. Thus, in the completion of the filter body from a cuboid, consisting of a plurality of their parallelepiped filter segments filter body less filter material must be removed, so that the filter material can be better utilized and less waste. The available filter segments are used as best as possible. In addition, due to its space-saving shape allows a inventively shaped filter element use as a common part for many different vehicle types.
Besonders zu bevorzugende Ausführungen und Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Particularly preferred embodiments and developments of the invention are the subject of the dependent claims.
Vorzugsweise weist bei einer Partikelfilteranordnung, bei der der Filterkörper eine obere, eine untere und zwei seitliche Begrenzungsflächen, die dem Gehäuse zugeordnet sind sowie zwei stirnseitige Begrenzungsflächen, die der Abgaseintrittsöffnung respektive der Abgasaustrittsöffnung zugeordnet sind, aufweist, eine der dem Gehäuse zugeordneten Begrenzungsflächen eine konvexe Form auf. Damit wird gewährleistet, dass der Filterkörper auch beim Betrieb der Brennkraftmaschine sicher im Gehäuse gehalten ist. Derselbe Vorteil wird mit dem wenigstens einen verrundeten Übergang zwischen der oberen respektive der unteren zu den seitlichen Begrenzungsflächen erzielt.Preferably, in a particulate filter arrangement in which the filter body has an upper, a lower and two lateral boundary surfaces, which are assigned to the housing and two end boundary surfaces, which are associated with the exhaust gas inlet opening and the exhaust gas outlet, one of the housing associated with the boundary surfaces has a convex shape on. This ensures that the filter body is securely held in the housing during operation of the internal combustion engine. The same advantage is achieved with the at least one rounded transition between the upper and the lower to the lateral boundary surfaces.
Sehr vorteilhaft ist es, wenn sich die Radien einer konvexen Form einer Begrenzungsfläche sowie der Verrundung der Übergänge an einer zum Halten des Filterkörpers im Gehäuse erforderlichen Haltekraft orientiert. Dabei wird davon ausgegangen, dass zwischen Filterkörper und Gehäuse formbedingt ein gewisser Kraft- oder Reibschluss, gegebenenfalls auch Formschluss, gegeben ist, der ein Halten des Filterkörpers im Gehäuse gewährleistet. Radien und Verrundungen werden jeweils minimal, jedoch so groß, dass der Filterkörper im Gehäuse betriebssicher gehalten ist, gewählt. Damit wird einerseits ein Sicherer Halt des Filterkörpers im Gehäuse erreicht und andererseits werden die oben beschriebenen Vorteile beibehalten.It is very advantageous if the radii of a convex shape of a boundary surface and the rounding of the transitions are oriented on a holding force required to hold the filter body in the housing. It is assumed that between the filter body and housing due to the shape of a certain force or frictional engagement, optionally also positive engagement, is given, which ensures holding the filter body in the housing. Radii and fillets are each minimized, but so large that the filter body is kept safe in the housing selected. Thus, on the one hand, a secure hold of the filter body is achieved in the housing and on the other hand, the advantages described above are maintained.

Als zweckmäßig hat es sich erwiesen, wenn der Querschnitt des Filterkörpers im Zwischenstand eine Kantenlänge von ca. 135 mm bis ca. 160 mm, insbesondere von ca. 140 mm bis ca. 145 mm, aufweist, sodass sich eine Querschnittsfläche von ca. 182 mm2 bis ca. 256 mm2, insbesondere von ca. 196 mm2 bis ca. 210 mm2, ergibt. In der endgültigen Form reduziert sich die Querschnittsfläche des Filterkörpers um die bei der Herstellung seiner endgültigen Form entfernten Bereiche. Vorzugsweise beträgt die Querschnittsfläche des fertigen Filterkörpers ca. 175 mm2 bis ca. 190 mm2, insbesondere ca. 180 mm2 bis ca. 185 mm2.It has proven to be expedient if the cross section of the filter body in the intermediate state has an edge length of about 135 mm to about 160 mm, in particular from about 140 mm to about 145 mm, so that a cross-sectional area of about 182 mm 2 to about 256 mm 2 , in particular from about 196 mm 2 to about 210 mm 2 results. In the final form, the cross-sectional area of the filter body is reduced by the areas removed in the production of its final shape. Preferably, the cross-sectional area of the finished filter body is about 175 mm 2 to about 190 mm 2 , in particular about 180 mm 2 to about 185 mm 2 .
