Abstract

Die vorliegende Erfindung betrifft eine abgasführende Komponente (2) einer Abgasanlage (1) für eine Brennkraftmaschine, insbesondere in einem Kraftfahrzeug. Die Komponente (2) umfasst ein Rohr (4), das von einem Längsende (6) zum anderen Längsende (7) von Abgas durchströmbar ist und das zwischen seinen Längsenden (6, 7) einen Längsabschnitt (8) aufweist, dessen Wandung (9) mit einer Perforation (10) versehen ist. Die Komponente (2) weist außerdem ein Gehäuse (5) auf, welches das Rohr (4) in Umfangsrichtung umhüllt und mit dem das Rohr (4) sowohl in einem das eine Längsende (6) aufweisenden Endbereich (11) als auch in einem das andere Längsende (7) aufweisenden anderen Endbereich (12) fest verbunden ist. Damit die Komponente (2) dennoch den im Betrieb auftretenden thermischen Belastungen widerstehen kann, ist die Perforation (10) so ausgestaltet, dass der Längsabschnitt (8) thermische Längsdehnungskräfte zwischen Rohr (4) und Gehäuse (5) durch elastische Verformung aufnehmen kann.
