Description
Die Erfindung betrifft eine Ansaugleitung mit Geräuschdämpfung zum Reduzieren von Geräuschen, die von der Ansaugleitung erzeugt werden, die in einem Ansaugsystem eines Fahrzeugmotors angewendet wird.The The invention relates to a noise attenuation intake duct for reducing noise, which are generated by the intake manifold, in an intake system a vehicle engine is applied.
Im Allgemeinen wird ein Ansaugsystem eines Fahrzeuges zum Ansaugen von Reinluft in einen Motor und zum Dämpfen von Ansauggeräuschen verwendet, die von dem Motor erzeugt werden.in the Generally, a suction system of a vehicle for sucking used by clean air in an engine and to dampen intake noise, which are generated by the engine.
Das Ansaugsystem wird üblicherweise von einer Ansaugleitung, einem Luftfilter und einem Luftleitkanal gebildet. Jedoch besteht bei einer für den Luftstrom ausgelegten Ansaugleitung ein Nachteil darin, dass diese keine Geräuschreduzierungswirkung hat.The Intake system becomes common from a suction duct, an air filter and an air duct educated. However, there is one designed for the air flow Suction line a disadvantage in that this no noise reduction effect Has.
Die
Mit der Erfindung wird eine Ansaugleitung geschaffen, die einstückig mit einer Geräuschdämpfungseinrichtung ausgebildet ist, um die Geräuschreduzierungswirkung zu verbessern, wodurch die Produktivität erhöht wird und der Raum in dem Ansaugsystem minimiert wird.With The invention provides a suction conduit which is integral with a noise damping device is designed to the noise reduction effect improve productivity and increase space in the area Intake system is minimized.
Dies wird gemäß der Erfindung durch eine Ansaugleitung nach den Merkmalen aus dem Anspruch 1 erreicht. Vorteilhafte Weiterbildungen sind in den Unteransprüchen beschrieben.This is according to the invention achieved by an intake pipe according to the features of claim 1. Advantageous developments are described in the subclaims.
Die
Erfindung wird mit Bezug auf die Zeichnung näher erläutert. In der Zeichnung zeigt
Mit Bezug auf die Zeichnung wird eine bevorzugte Ausführungsform der Erfindung beschrieben.With Referring to the drawing, a preferred embodiment of the invention.

Wie aus dem zuvor genannten ersichtlich, besteht ein Vorteil der Erfindung darin, dass sich die Ansaugleitung des Ansaugsystems eines Fahrzeugmotors in einem bestimmten Abschnitt davon erweitert, und die Trennwand ist zwischen der Innenseite des ausgedehnten Abschnitts und einem Rohrstutzen montiert, um eine Resonanzkammer dazwischen zu erreichen. Auch ist ein Abzweigrohr zum Verbinden der Resonanzkammer mit der Innenseite des Ansaugschlauches vorgesehen, wodurch die Geräuschreduzierungswirkung der Ansaugleitung mit einer einfachen Struktur verbessert wird.As can be seen from the aforementioned, There is an advantage of the invention in that the intake pipe of the intake system of a vehicle engine expands in a certain portion thereof, and the partition wall is mounted between the inside of the extended portion and a pipe stub to reach a resonance chamber therebetween. Also, a branch pipe for connecting the resonance chamber to the inside of the suction hose is provided, whereby the noise reduction effect of the suction pipe is improved with a simple structure.
