Abstract

Die Erfindung betrifft eine Vorrichtung zur Geräuschübertragung in einem Kraftfahrzeug, die ein Gehäuse (1) mit einer inneren Trennwand (2) umfaßt. Durch das Gehäuse (1) und die innere Trennwand (2) sind zwei getrennte Teilräume (3, 4) begrenzt. Es ist eine durch eine Schwenklageröffnung (9) der Trennwand (2) hindurchgeführte und im Bereich der Schwenklageröffnung (9) um eine Schwenkachse (5) schwenkbar gelagerte Übertragungsklappe (6) vorgesehen, mittels derer die beiden Teilräume (3, 4) aufgeteilt sind. Der erste Teilraum (3) ist mit einem Ansaugrohr (17) einer Brennkraftmaschine und der zweite Teilraum (4) mit einem Innenraum des Kraftfahrzeuges schallübertragend verbunden. Zwischen einem Rand (10) der Schwenklageröffnung (9) und der Übertragungsklappe (6) ist ein Spalt (11) vorgesehen, der mittels einer Membran (12) druckdicht verschlossen ist.

The invention relates to a device for transmitting noise in a motor vehicle, comprising a housing (1) with an inner partition (2). Through the housing (1) and the inner partition (2) two separate subspaces (3, 4) are limited. There is a through a pivot bearing opening (9) of the partition (2) guided and pivotally mounted in the region of the pivot bearing opening (9) about a pivot axis (5) transmission flap (6) by means of which the two subspaces (3, 4) are divided. The first subspace (3) is connected to an intake pipe (17) of an internal combustion engine and the second subspace (4) connected to an interior of the motor vehicle sound transmitting. Between a rim (10) of the pivot bearing opening (9) and the transfer flap (6), a gap (11) is provided which is pressure-tightly sealed by means of a membrane (12).
