Filtervorrichtung, insbesondere Dieselpartikelfilter, für eine Abgasanlage einer BrennkraftmaschineFilter device, in particular diesel particulate filter, for an exhaust system of an internal combustion engine
Stand der TechnikState of the art
Die Erfindung betrifft eine Filtervorrichtung, insbesondere einen Dieselpartikelfilter, für eine Abgasanlage einer Brennkraftmaschine, entsprechend dem Oberbegriff des Anspruchs 1.The invention relates to a filter device, in particular a diesel particulate filter, for an exhaust system of an internal combustion engine, according to the preamble of claim 1.
Aus der DE 101 28 936 Al ist ein Partikelfilter bekannt, dessen Filterelemente ringförmig um eine zentrische Abstützung angeordnet sind. Die Abstützung besteht aus einem zylindrischen Stützrohr und einem Stützzapfen. Die Filterelemente weisen abströmseitig einen äußeren Haltering auf. Anströmseitig sind die Filterelemente jedoch nur durch die beschriebene zentrische Abstützung stabilisiert. Diese Anordnung reagiert daher empfindlich auf in den Partikelfilter eingeleitete Schwingungen.From DE 101 28 936 Al a particle filter is known, the filter elements are arranged in a ring around a central support. The support consists of a cylindrical support tube and a support pin. The filter elements have an outer retaining ring downstream. On the inflow side, however, the filter elements are stabilized only by the described centric support. Therefore, this arrangement is sensitive to vibrations introduced into the particulate filter.
In der DE 203 13 032 Ul wird vorgeschlagen, die Anordnung gemäß der DE 101 28 936 zu verbessern, indem die Filterelemente eines Partikelfilters anströmseitig durch einen Stützring gehalten sind, wobei der Stützring über Speichen mit dem Filtergehäuse verbunden ist. Um eine gute Stützwirkung zu erzielen, ist eine Vielzahl von Speichen erforderlich, die jeweils einenends an dem Stützring und anderenends an dem Filtergehäuse befestigt werden müssen. Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine möglichst robuste Filtervorrichtung bereitzustellen, die leicht herstellbar ist und während des Betriebs spannungsarm ist.In DE 203 13 032 Ul it is proposed to improve the arrangement according to DE 101 28 936 by the filter elements of a particulate filter are held upstream by a support ring, wherein the support ring is connected via spokes to the filter housing. In order to achieve a good support effect, a plurality of spokes is required, which must be attached at one end to the support ring and the other end to the filter housing. On this basis, the present invention has the object to provide a robust as possible filter device that is easy to produce and low-voltage during operation.
Diese Aufgabe wird durch eine Filtervorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen angegeben.This object is achieved by a filter device having the features of claim 1. Advantageous embodiments are specified in the subclaims.
Vorteile der ErfindungAdvantages of the invention
Durch Anordnung eines ringförmigen Dämpfungselements zwischen der Stützstruktur und dem Gehäuseelement können sowohl die Stützstruktur als auch das Gehäuseelement mit vergleichsweise hohen Toleranzen behaftet sein.By arranging an annular damping element between the support structure and the housing element, both the support structure and the housing element can be subject to comparatively high tolerances.
Gleichzeitig ist gewährleistet, dass die Filtervorrichtung auch bei hoher thermischer Belastung spannungsarm bleibt, da die Stützstruktur und das Gehäuseelement durch das räumlich zwischengeschaltete Dämpfungselement voneinander entkoppelt sind. Durch die ringförmige Ausbildung desAt the same time it is ensured that the filter device remains stress-free even at high thermal stress, since the support structure and the housing element are decoupled from each other by the spatially interposed damping element. Due to the annular formation of the
Dämpfungselements kann die Filtervorrichtung in besonders einfacher Weise montiert werden. Dabei ist der aus Stützstruktur, Dämpfungselement und Gehäuseelement gebildete Aufbau der Filtervorrichtung robust und schwingungsunempfindlich.Damping element, the filter device can be mounted in a particularly simple manner. In this case, the structure of the filter device formed from support structure, damping element and housing element is robust and insensitive to vibrations.
Ein Verschweißen der Filterelemente mit einem Stützring, der seinerseits mit einer Stützscheibe verschweißt ist, die wiederum mit dem Gehäuseelement verschweißt ist, und die hierdurch entstehende sehr steife Struktur ist bei der erfindungsgemäßen Vorrichtung nicht mehr angedacht. Damit wird die bei einer solchen Konstruktion entstehende Schwierigkeit vermieden, dass die großen Toleranzen der Stützstruktur und des Gehäuseelements und die sich hieraus ergebenden vergleichsweise große Abstände zwischen den einzelnen Komponenten über eine Schweißverbindung überbrückt werden müssen.A welding of the filter elements with a support ring, which in turn is welded to a support disk, which in turn is welded to the housing member, and the resulting very rigid structure is no longer considered in the inventive device. Thus, the difficulty that arises in such a construction is avoided, that the large tolerances of the support structure and the housing member and the resulting comparatively large distances between the individual components must be bridged via a welded joint.
Die Stützstruktur kann sowohl in einer zur Durchströmrichtung der Filtervorrichtung parallelen Richtung als auch in einer zur Durchströmrichtung der Filtervorrichtung senkrechten Richtung bewegbar sein. Bei Bewegbarkeit in paralleler Richtung kann die axiale Ausdehnung der Filterelemente ausgeglichen werden, indem sich die Stützstruktur in einer zur Durchströmrichtung parallelen Richtung innerhalb des Gehäuseelements verschiebt. Ist die Stützstruktur optional oder zusätzlich in einer zur Durchströmrichtung senkrechten Richtung bewegbar, können Schwingungen in einer zur Durchströmrichtung senkrechten Richtung kompensiert werden, ohne dass das Gehäuseelement mitschwingt.The support structure can be movable both in a direction parallel to the flow direction of the filter device and in a direction perpendicular to the flow direction of the filter device. When movable in a parallel direction, the axial extent of the filter elements can be compensated by the support structure shifts in a direction parallel to the flow direction within the housing member. If the support structure is optionally or additionally movable in a direction perpendicular to the flow direction, vibrations in a direction perpendicular to the flow direction can be compensated for without the housing element resonating.
Das Dämpfungselement dämpft die Bewegung zwischen der Stützstruktur und dem Gehäuseelement. Dies erhöht die Lebensdauer der Bauteile und verringert dieThe damping element dampens the movement between the support structure and the housing element. This increases the life of the components and reduces the

In addition, it can be manufactured with comparatively large manufacturing tolerances.
In vorteilhafter Weise ist das Dämpfungselement mit der Stützstruktur und/oder dem Gehäuseelement verbunden, insbesondere durch eine Rastverbindung. Somit kann dieAdvantageously, the damping element is connected to the support structure and / or the housing element, in particular by a latching connection. Thus, the
Einbaulage des Dämpfungselements besonders gut definiert werden.Installation position of the damping element are particularly well defined.
Eine Weiterbildung der Erfindung sieht vor, dass die Stützstruktur ringförmig ausgebildet ist. Dies ermöglicht eine gleichmäßige Befestigung der Filterelemente an der Stützstruktur, die die Filterelemente auch in einem radial äußeren Bereich stabilisieren kann. Außerdem können die Filterelemente über die ringförmige Stützstruktur und das ringförmige Dämpfungselement in einfacher Weise zentriert in dem Gehäuseelement angeordnet werden.A development of the invention provides that the support structure is annular. this makes possible a uniform attachment of the filter elements to the support structure, which can stabilize the filter elements in a radially outer region. In addition, the filter elements can be easily centered in the housing element via the annular support structure and the annular damping element.
Eine weitere Ausführungsform der Erfindung sieht vor, dass die Filterelemente einen zentrischen Hohlraum bilden, in dem eine zusätzliche Stützhülse aufgenommen ist. Diese verleiht den Filterelementen zusätzliche Stabilität. Wenn zwischen den Filterelementen und der Stützhülse Dämpfungsmaterial, insbesondere aus Drahtgestrick, angeordnet ist, können auch in diesem Bereich Schwingungen wirkungsvoll aufgenommen werden.A further embodiment of the invention provides that the filter elements form a centric cavity, in which an additional support sleeve is received. This gives the filter elements additional stability. If damping material, in particular made of wire mesh, is arranged between the filter elements and the support sleeve, vibrations can also be effectively absorbed in this region.

Von dem ersten Abschnitt 28 der Stützstruktur 24 geht ein zweiter Abschnitt 32 ab, der zylindrisch ausgebildet ist und konzentrisch zur Wand des Gehäuseelements 12 verläuft. Von dem Abschnitt 32 erstreckt sich schließlich ein dritter Abschnitt der Stützstruktur 24 in radialer Richtung nach außen. Der Abschnitt 34 erstreckt sich im Wesentlichen parallel zum Abschnitt 28. Die Abschnitte 32 und 34 der Stützstruktur 24 bilden einen Einbauraum, in den dasThe support structure 24 has a first annular disk-shaped section 28 to which the filter elements 16 are fastened by means of a weld 30. From the first portion 28 of the support structure 24 is a second portion 32 which is cylindrical and concentric with the wall of the housing member 12 extends. From Finally, in section 32, a third section of support structure 24 extends outward in the radial direction. The section 34 extends substantially parallel to the section 28. The sections 32 and 34 of the support structure 24 form an installation space into which the
Dämpfungselement 26 über nicht dargestellte Rastelemente einrastbar ist. Somit ist das Dämpfungselement 26 fest mit der Stützstruktur 24 verbunden. Das Dämpfungselement 26 ist im Gehäuseelement 12 mit einer leichten Presspassung aufgenommen.Damping element 26 can be latched via latching elements, not shown. Thus, the damping element 26 is fixedly connected to the support structure 24. The damping element 26 is received in the housing member 12 with a slight interference fit.
Benachbart zum Innenraum 18 der Filterelemente 16 ist eine zusätzliche Stützhülse 36 vorgesehen. Diese weist eine Stirnscheibe 38 auf, an der die Filterelemente 16 über eine nicht dargestellte Verschweißung befestigt sind. Von derAdjacent to the interior 18 of the filter elements 16, an additional support sleeve 36 is provided. This has an end plate 38 to which the filter elements 16 are fastened via a weld, not shown.

Somit kann die mit einer starken Temperaturerhöhung einhergehende Ausdehnung der Filterelemente durch ein Verschieben der Stützstruktur 24 in mit 48 bezeichneten Richtungen ausgeglichen werden. Die Filterelemente 16 sind auch radial, das heißt in einer zur Durchströmrichtung senkrechten Richtung bewegbar.
