Abstract

Die Erfindung betrifft ein schallreduzierendes Bauteil für ein Luftführungsrohr (1) für die Verbrennungsmaschine, insbesondere für den Turbolader, eines Kraftfahrzeugs, das als Zuführkanal für Frischluft und/oder als Abführkanal für Abgase an die Verbrennungsmaschine angeschlossen wird. Hierbei weist das schallreduzierende Bauteil wenigstens eine Absorptionskammer (9, 10), die fluidleitend mit dem Luftstrom (P) verbunden ist, auf. Um die Herstellung eines solchen Bauteils zu vereinfachen bei gleichzeitig schneller Montage des Luftführungsrohres an den Turbolader, wird vorgeschlagen, dass eine solche Vorrichtung eine einstückig hergestellte metallische Anschluss-/Dämpfungseinheit (4) umfasst, die als Anschlussstück für das Rohrende eine Schnellkupplung (5) und ein in das anschlussseitige Rohrende (3) eingeschobenes Inlet (6) aufweist, dass die Absorptionskammer (9, 10) zwischen dem Inlet (6) und der Rohrinnenwandung (7) ausgebildet ist und die Einheit (4) am Rohr (1) befestigbar ist.

The invention relates to a sound-reducing component for an air duct (1) for the internal combustion engine, in particular for the turbocharger, a motor vehicle, which is connected as a supply channel for fresh air and / or as a discharge channel for exhaust gases to the internal combustion engine. In this case, the sound-reducing component has at least one absorption chamber (9, 10) which is fluid-conductively connected to the air flow (P). In order to simplify the production of such a component with simultaneous rapid assembly of the air duct to the turbocharger, it is proposed that such a device comprises a one-piece metal connection / damping unit (4), which as a connector for the pipe end a quick coupling (5) and an inlet (6) inserted into the connection-side tube end (3) has the absorption chamber (9, 10) formed between the inlet (6) and the tube inner wall (7) and the unit (4) can be fastened to the tube (1) ,
