Abstract
Description
"Abgaskatalysatorbefestigung" Zusatz zu Patent ....... (Patentanmeldung P 23 18 126.2) Die Erfindung betrifft eine Abgaskatalysatorbefestigung, insbesondere für Kraftfahrzeuge, die einen Katalysatorkörper in einer Auspuffleitung so einspannt, daß er weitgehend vor Abgas- und/oder Fahrzeugschwingungen geschützt ist, und wobei die Befestigung den Katalysatorkörper in radialer und axialer Richtung elastisch abstützt, nach Patent ...,.. (Patentanmeldung P 23 18 126.2)."Exhaust catalytic converter attachment" addendum to patent ....... (patent application P 23 18 126.2) The invention relates to a catalytic converter mounting, in particular for motor vehicles that clamps a catalytic converter body in an exhaust pipe in such a way that that it is largely protected from exhaust gas and / or vehicle vibrations, and where the attachment of the catalyst body is elastic in the radial and axial directions supports, according to patent ..., .. (patent application P 23 18 126.2).
Im Hauptpatent ......... (Patentanmeldung P 23 18 126.2) ist eine Befestigung behandelt, bei der die radial elastische Abstützung des Katalysatorkörpers durch ein hitzebeständiges Isoliermaterial, z.B. Keramikwolle, und die axial elastische Abstützung durch zwei vorgespannte ringförmige Membranen erfolgt, die auch aus sich schuppenförmig überlappenden Einzelteilen bestehen können.In the main patent ......... (patent application P 23 18 126.2) is one Fastening treated in which the radially elastic support of the catalyst body by a heat-resistant insulating material, e.g. ceramic wool, and the axially elastic Support is provided by two prestressed annular membranes, which are also made up of themselves may exist flaky overlapping items.
Es ist Aufgabe der vorliegenden Erfindung, eine weitere vorteilhafte Katalysatorbefestigung durch eine radial elastische Abstützung zu schaffen.It is the object of the present invention to provide a further advantageous To create catalyst attachment by a radially elastic support.
Die Aufgabe ist erfindungsgemäß dadurch gelöst, daß die radial elastische Abstützung durch metallische Federlaschen erfolgt, die den hohlraum zwischen Katalysatorkörper und Innenwandung eines Rohrteilstücks in der Auspuffleitung überbrücken.The object is achieved according to the invention in that the radially elastic Supported by metallic spring straps is made that the cavity between the catalyst body and the inner wall of a pipe section in the exhaust line bridge.
In Ausgestaltung der Erfindung sind die Federlaschen an einem der Innenform der Auspuffleitung oder der Außenform des Katalysatorkörpers angepaßten Mantel befestigt. In an embodiment of the invention, the spring tabs are on one of the Inner shape of the exhaust pipe or the outer shape of the catalyst body adapted Coat attached.
Um Wärmedehnungen aufnehmen zu können, weist der Mantel vorzugsweise einen Schlitz auf, der sich über seine gesamte Länge erstreckt. In order to be able to absorb thermal expansion, the jacket preferably has a slot that extends its entire length.
Um die Wärmedehnungen des >Iantels auszugleichen, können die Federlatchen U-förmig abgebogen sein und mit ihren freien Enden an der Innenwandung der Auspuffleitung anliegen. In order to compensate for the thermal expansion of the> jacket, the spring tabs Be bent in a U-shape and with their free ends on the inner wall of the exhaust line issue.
Bei einer anderen Ausführungsform der Erfindung liegen die freien Enden der Federlaschen außen am Katalysatorkörper an. In another embodiment of the invention, the free ones are Ends of the spring tabs on the outside of the catalyst body.
Dies ist nach der Erfindung auch dadurch erreichbar, daß die Federlaschen V-förmig abgewinkelt sind. According to the invention, this can also be achieved in that the spring tabs Are angled in a V-shape.
In der Zeichnung ist die Erfindung in zwei Ausführungsformen beispielsweise dargestellt. Es zeigen Fig. 1 einen Längsschnitt durch die Katalysatoranordnung in der Auspuffleitung mit Befestigung und Abstützung, Fig. 2 einen Querschnitt nach der Linie II-II in Fig. 1, und Fig. 3 einen Schnitt entsprechend Fig.2 durch eine andere Ausführungsform der Erfindung. In the drawing, the invention is in two embodiments, for example shown. 1 shows a longitudinal section through the catalytic converter arrangement in the exhaust line with attachment and support, Fig. 2 shows a cross section the line II-II in Fig. 1, and 3 shows a section accordingly Fig.2 by another embodiment of the invention.
Fig.1 zeigt ein in eine Auspuffleitung eingebautes Rohrteilstück 1 mit Befestigungsflanschen 2 und 3. Zwei ringförmige Membranen 4 und 5 dienen für den Katalysatorkörper 6 als axial elastische Abstützung in der Auspuffleitung. Der Katalysatorkörper 6 wird von einem Mantel 7 aus hitzebeständigem Material umschlossen, auf dem metallische Federlaschen 8 befestigt sind, die sich mit ihren freien Enden 9 in radialer Richtung beweglich und elastisch gegen die Innenwandung des Rohrteilstücks 1 abstützen. Es ist aber auch denkbar, daß der Mantel der Innenform der Auspuffleitung angepaßt ist und die Federlaschen sich mit ihren freien Enden gegen den Katalysatorkörper abstützen. Beide Ausführungsformen sind geeignet, den Katalysatorkörper 6 radial elastisch zu zentrieren und zu fixieren.1 shows a pipe section 1 installed in an exhaust line with mounting flanges 2 and 3. Two annular membranes 4 and 5 are used for the catalyst body 6 as an axially elastic support in the exhaust line. Of the Catalyst body 6 is enclosed by a jacket 7 made of heat-resistant material, are attached to the metallic spring tabs 8, which are with their free ends 9 movable in the radial direction and elastic against the inner wall of the pipe section 1 support. But it is also conceivable that the jacket of the inner shape of the exhaust line is adapted and the spring tabs with their free ends against the catalyst body prop up. Both embodiments are suitable, the catalyst body 6 radially to center and fix elastically.
Fig.2 und 3 zeigen im Querschnitt den Katalysatorkörper 6 zentrisch gelagert und umschlossen von dem Mantel 7, auf dem in Abständen Federlaschen 8, ii befestigt sind, die mit ihren freien Enden 9, 12 sich beweglich gegen die Innenwandung des Rohrteilstücks 1 abstützen. Um Wärmedehnungen aufnehmen zu können, ist der Mantel 7 mit einem durchgehenden Schlitz 10 versehen.2 and 3 show the catalyst body 6 centrally in cross section stored and enclosed by the jacket 7, on which spring tabs 8, ii are attached, which with their free ends 9, 12 are movable against the inner wall of the pipe section 1. In order to be able to absorb thermal expansion, the jacket 7 is provided with a continuous slot 10.
