Abstract

Die Erfindung betrifft eine Abgasbehandlungseinrichtung (1) für eine Abgasanlage (4) einer Brennkraftmaschine, insbesondere eines Straßenfahrzeugs, mit einem Gehäuse (2), das zumindest einen Innenraum (3) umhüllt, und mit mindestens einem Durchgangsrohr (5), das den Innenraum (3) unterbrechungsfrei durchsetzt und das an zwei voneinander entfernten Befestigungsstellen (6, 7) fest mit dem Gehäuse (2) verbunden ist.The invention relates to an exhaust gas treatment device (1) for an exhaust system (4) of an internal combustion engine, in particular of a road vehicle, with a housing (2) which encloses at least one interior space (3) and with at least one passage pipe (5) which surrounds the interior space (5). 3) interspersed without interruption and at two remote fastening points (6, 7) fixed to the housing (2) is connected.

Zur Kompensation thermisch bedingter Dehnungseffekte kann das Durchgangsrohr (5) zwischen den Befestigungsstellen (6, 7) zumindest einen Dehnungsausgleichsabschnitt (8) aufweisen, in dem eine Wand (10) des Durchgangsrohrs (5) sich in Umfangsrichtung abwechselnde, die Wand (10) durchsetzende Schlitze (12) und gegenüber benachbarten Wandabschnitten (13, 14) des Durchgangsrohrs (5) vorstehende Streifen (11) aufweist.

Figure imgaf001
To compensate for thermally induced expansion effects, the passage tube (5) between the attachment points (6, 7) at least one expansion compensation section (8), in which a wall (10) of the passage tube (5) alternately in the circumferential direction, the wall (10) passing through Slots (12) and opposite adjacent wall portions (13, 14) of the passage tube (5) projecting strip (11).
