Abstract
Vorderwagen eines Kraftfahrzeugs, beinhaltend eine vordere Stirnwand die ihrerseits den Motorraum von der Fahrgastzelle abtrennt sowie motorseitig mit einem akustisch wirksamen Material belegt ist und an der ein oder mehrere Aggregate und/oder Einrichtungen befestigt sind respektive sich an dieser abstützen, dadurch gekennzeichnet, dass zur vorderen Stirnwand (1) weisende freie Gehäuseflächen der an der Stirnwand (1) angeordneten Aggregate (6) und/oder Einrichtungen mit zumindest einer Schicht aus ausschließlich einem schalldämmenden Material (4) und die übrigen in den Motorraum weisenden freien Gehäuseflächen derselben mit zumindest einer Schicht aus ausschließlich einem schallabsorbierenden Material (5) belegt sind.Front of a motor vehicle, including a front end wall which in turn separates the engine compartment from the passenger compartment and the engine side is covered with an acoustically effective material and to which one or more units and / or devices are attached respectively supported on this, characterized in that the front Front wall (1) facing free housing surfaces of the front wall (1) arranged units (6) and / or facilities with at least one layer of only a sound insulating material (4) and the other pointing into the engine compartment free housing surfaces thereof with at least one layer exclusively a sound-absorbing material (5) are occupied.
Description
Die Erfindung betrifft einen Vorderwagen eines Kraftfahrzeugs nach dem Oberbegriff des Anspruchs 1.The invention relates to a front end of a motor vehicle according to the preamble of claim 1.
Aus der
Um eine höhere Schallabschirmung der Fahrgastzelle zu erzielen, wird des Weiteren vorgeschlagen, einen Bremskraftverstärker, der seinerseits selbst zur Geräuschentwicklung im Motorraum beiträgt und überwiegend direkt an der Stirnwand befestigt ist, mit akustisch wirksamen Material zu belegen, um eine Schallübertragung der in demselben erzeugten Geräusche in die Fahrgastzelle zu mindern.In order to achieve a higher soundproofing of the passenger compartment, it is further proposed, a brake booster, which in turn contributes to the noise in the engine compartment and is mainly attached directly to the front wall, to prove with acoustically effective material to a sound transmission of the noise generated in the same to reduce the passenger compartment.
Derartige Vorschläge sind beispielsweise den Druckschriften
Aufgabe vorliegender Erfindung ist es, die akustisch wirksamen Maßnahmen an einem Vorderwagen eines Kraftfahrzeugs derart zu verbessern, dass eine größtmögliche Schalldämmung und Schallabsorption erzielbar ist.Object of the present invention is to improve the acoustically effective measures on a front end of a motor vehicle such that the greatest possible sound insulation and sound absorption can be achieved.
Im Rahmen von umfangreichen Versuchen wurde nämlich gefunden, dass nicht nur Aggregate und Einrichtungen, die selbst aktiv Geräusche erzeugen, wie beispielsweise Bremskraftverstärker, sondern auch jegliche anderen Aggregate und Einrichtungen, die im Vorderwagen installiert sind, u. a. auch durch Eigenresonanz erheblich zur Schallübertragung und -weiterleitung von Schall aus dem Motorraum in die Fahrgastzelle beitragen. Ferner wurde gefunden, dass gerade durch eine besondere An- bzw. Zuordnung der beiden wesentlichen an sich bekannten akustisch wirksamen Maßnahmen in Form einer Schalldämmung und einer Schallabsorption zu einem wirksamen und effektiven Ergebnis gemäß obiger Aufgabenstellung führt.In the context of extensive tests, it has been found that not only are units and devices which themselves actively generate noise, such as brake booster, but also any other units and devices which are installed in the front end, u. a. Also contribute significantly by self-resonance to the sound transmission and transmission of sound from the engine compartment in the passenger compartment. Furthermore, it has been found that leads to an effective and effective result according to the above task just by a special application or assignment of the two essential known acoustically effective measures in the form of sound insulation and sound absorption.
Ausgehend von dieser Erkenntnis wird die Aufgabe in Verbindung mit den Merkmalen im Oberbegriff des Anspruchs 1 dadurch gelöst, dass die zur vorderen Stirnwand weisenden freien Gehäuseflächen der an der Stirnwand angeordneten Aggregate und/oder Einrichtungen mit zumindest einer Schicht aus ausschließlich einem schalldämmenden Material und die übrigen in den Motorraum weisenden freien Gehäuseflächen derselben mit zumindest einer Schicht aus ausschließlich einem schallabsorbierenden Material belegt sind.Based on this finding, the object is achieved in conjunction with the features in the preamble of claim 1, characterized in that the front end wall facing free housing surfaces arranged on the end wall units and / or devices with at least one layer of only one sound-absorbing material and the rest in the engine compartment facing free housing surfaces thereof are covered with at least one layer of exclusively a sound-absorbing material.
Das schalldämmende Material ist vorzugsweise eine Schwerschicht aus Bitumen und/oder Kunststoff und/oder aus einem geschlossenporigen Schaum und/oder einer Metallfolie oder Metallplatte. Das schallabsorbierende Material kann hierbei ein offenporiger Schaum, ein Faservlies, ein Feinvlies und/oder ein mikroperforierter Absorber sein.The sound-insulating material is preferably a heavy layer of bitumen and / or plastic and / or a closed-cell foam and / or a metal foil or metal plate. The sound-absorbing material may in this case be an open-pored foam, a non-woven fabric, a fine nonwoven and / or a microperforated absorber.
Die Erfindung wird nachstehend anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert.The invention will be explained in more detail with reference to an embodiment shown in the drawing.
