pammschlld für einen Kraftfabrzeugunte£bodenpammschlld for a motor vehicle underbody BeschreibungDescription
Das Gebrauchsmuster betrifft ein Dämmschild für einen Kraftfahrzeugunterboden, bei dem auf einem plattenförmigen Trägerteil eine Dämmschicht angeordnet 1st, die auf der dem Trägerteil gegenüberliegenden Seite durch eine Schutzfolie abgedeckt 1st. Durch det Einbau von Katalysatoren und aych bei Magermutoren treten erhöhte Temperaturen Im Abgasbereich auf. Dies erfordert den Einbau von Hitzeschilder zwischen dem Abgassystem und dem Fahrzeuguntetboden. Hitzeschilde sind auch deshalb erforderlich, weil im Hinblick auf einen niedrigen cw-Wert eine flachere Bauweise der Kraftfahrzeuge gefordert wird. Solche Hitzeschilde oder Dämmschilde werden als Abstrahlbleche aus hochglänzenden Stoffen oder als mehrlagige Schilde gemäß dem Gattungsbegriff ausgebildet, wobei da» Trägerteil normalerweise aus einem Aluminiumblech besteht, das schalenförmig gebogen ist.The utility model relates to an insulation shield for a motor vehicle underbody, in which an insulation layer is arranged on a plate-shaped support part, which is covered by a protective film on the side opposite the support part. The installation of catalytic converters and also lean-burn engines results in increased temperatures in the exhaust area. This requires the installation of heat shields between the exhaust system and the vehicle underbody. Heat shields are also necessary because a flatter design of motor vehicles is required in order to achieve a low drag coefficient. Such heat shields or insulation shields are designed as radiating plates made of high-gloss materials or as multi-layer shields in accordance with the generic term, with the support part normally consisting of an aluminum sheet that is bent into a shell shape.
Aufgrund der immer strenger werdenden Bestimmungen hinsichtlich der Geräuschdämmung bei Kraftfahrzeugen bietet es sich an, diese Dämmteile auch zur Schallisolierung auszunutzen. Allerdings wird der Schall durch das Trägerteil abgeschirmt, das den Schall reflektiert. Aufgabe des Gebrauchsmusters ist die Bereitstellung eines Dämm-Schildes, das neben wärmedämmenden auch echalldämmende Eigenschaften hat.Due to the increasingly strict regulations regarding noise insulation in motor vehicles, it is advisable to use these insulation parts for sound insulation. However, the sound is shielded by the support part, which reflects the sound. The purpose of the utility model is to provide an insulation shield that has sound-insulating properties as well as heat-insulating properties.
Diese Aufgabe wird nach dem Gebrauchsmuster dadurch gelöst, daß das Trägerteil Durchbrüche aufweist, die einen Schalleintritt in die Dämmschicht zulassen.This task is solved according to the utility model in that the support part has openings that allow sound to enter the insulation layer.
Das Gebrauchsmuster unterscheidet sich Insofern vom Stand der Technik, als der Schall in die Dämmschicht eintreten kann und somit in bestimmten Frequenzbereichen weltgehend absorbiert wird. Die Refle-The utility model differs from the state of the art in that the sound can penetrate the insulation layer and is thus largely absorbed in certain frequency ranges. The reflection
t &igr; &igr; > · < t &igr;&igr;> · <
xlon des Schalls aue dem Abgassystem wird reduziert. Die Wärmedämmfunktion des Dämmschildes bleibt unverändert bestehen.xlon of the sound from the exhaust system is reduced. The thermal insulation function of the insulation shield remains unchanged.
Eine Ausführungsform des Gebrauchsmusters sieht vor, daß das Tv:ägerteil als gelochtes Metallblech ausgebildet ist.One embodiment of the utility model provides that the TV support part is designed as a perforated metal sheet.
Eine weitere Ausführungsform des Gebrauchsmusters sieht vor, daß das Trägerteil als gitterartiges Metallteil ausgebildet ist. Diese gitterartige Struktur kann durch ein Drahtgitter, ein Drahtgewebe, ein Streckmetall aus Aluminium, verzinktem Stahl oder rostfreiem Stahl erzielt werden. Man kann auch einen anderen Stoff einsetzen, der eine ausreichende Wärmebeständigkeit aufweist.A further embodiment of the utility model provides that the carrier part is designed as a grid-like metal part. This grid-like structure can be achieved by a wire mesh, a wire mesh, an expanded metal made of aluminum, galvanized steel or stainless steel. Another material that has sufficient heat resistance can also be used.
Zur Abschirmung der Dämmschicht gegen Feuchtigkeitszutriit ist
vorgesehen, daS zwischen dem Trägerteil und der Dämmschicht eine schalldurchläsßige und feuchtigkeitsuudurchlässige Aluminiumfolie
angeordnet ist.
Eine sichere Feuchtigkeitsabschirmung ohne Behinderung des Schalldurchtritts erzielt man dadurch, daß die Dicke der Aluminiumfolie
weniger als 3 um beträgt.To shield the insulation layer against moisture ingress, a sound-permeable and moisture-permeable aluminum foil is arranged between the carrier part and the insulation layer.
Reliable moisture shielding without impeding the passage of sound is achieved by the fact that the thickness of the aluminum foil is less than 3 μm.
Die gleiche Wirkung erzielt man dadurch, daß auf die Dämmschicht eine wasserabweisende Schicht z.B. eine Metallschicht autgebracht ist. Diese wasserabweisende Schicht kann insbesondere durch Aufdampfen, Aufprägen oder Aufsprühen aufgebracht werden.The same effect can be achieved by applying a water-repellent layer, e.g. a metal layer, to the insulation layer. This water-repellent layer can be applied in particular by vapor deposition, embossing or spraying.
Man kann auch eine Dämmschicht mit feuchtigkeitswabweisenden Eigenschaften derart vorsehen, daß als Dämmschicht eine geknitterte Aluminiumfolie in einer oder mehreren Lagen vorgesehen ist. "5 Eine Ausführungeform des Gebrauchsmusters wird im Folgenden unter Bezugnahme auf die anliegende Zeichnung erläutert, in der darstellen: It is also possible to provide an insulating layer with moisture-repellent properties in such a way that a crumpled aluminum foil in one or more layers is provided as the insulating layer. "5 An embodiment of the utility model is explained below with reference to the attached drawing, in which:
des nach der Erfindung und
Fig. 2 einen Teilschnitt durch das Dämmschild zur Erläuterungof the invention and
Fig. 2 a partial section through the insulation shield for explanation
des Aufbaues.of the structure.
DaJ Dämmschild 1 ist durch Prägen oder Ziehen an die Form des Kraftfahrzeugunterbodens angepaßt. £emäß Flg. 2 weiut das Dämmschild ein Trägerteil 2 auf, das als Lochblech dargestellt let. Es kann sich auch um ein Streckmetall oder dergleichen handeln. Das Trägerteil 2 ist normalerweise ein Aluminiumblech, das entsprechend geprägt oder gezogen ist. Das Trägerteil 2 in Form dieser Blechechale kann <&Lgr;&eegr;-stUcklg oder mehrstUckig ausgebildet sein. Das Trägerteil ?: hat eine glänzende Oberfläche, um eine hohe Wärmeabstrahlung sicherzustellen.The insulation shield 1 is adapted to the shape of the vehicle underbody by embossing or drawing. According to Fig. 2, the insulation shield has a carrier part 2, which is shown as a perforated sheet. It can also be an expanded metal or the like. The carrier part 2 is normally an aluminum sheet, which is embossed or drawn accordingly. The carrier part 2 in the form of this sheet metal tray can be made in one piece or in several pieces. The carrier part ?: has a shiny surface to ensure high heat radiation.
An das Trägerteil 2 schließt eine Dämmschicht 3 an, die im wesentlichen aus einer Wärmedämmatte besteht· Diese Dämmette besteht im wesentlichen aus organischen oder mineralischen Schäumen, aus einem Glasfaseraufbau oder dergleichen. Die Dämmschicht ist auf der Oberseite mit einer Aluminiumfolie 4 überzogen, die feuchtigkeitsundurchlässig und schallundurchläesig ist, um die Dämmschicht 3 sicher abzuschließen. The carrier part 2 is followed by an insulation layer 3, which essentially consists of a thermal insulation mat. This insulation mat essentially consists of organic or mineral foams, a glass fiber structure or the like. The insulation layer is covered on the top with an aluminum foil 4, which is impermeable to moisture and sound, in order to securely seal the insulation layer 3.
Die Löcher im Trägerteil lassen in entsprechendem Verhältnis /.ur Gesamtfläche des Trägerteils den Schall in die Dämmschicht, eintreten und bewirken dadurch eine entsprechende Schallminderung.The holes in the support part allow the sound to enter the insulation layer in proportion to the total surface area of the support part, thereby causing a corresponding reduction in sound.
Um einen Feuchtigkeitseintritt in die Dämmschicht 3 auszuschließen, kann man zwischen dem Trägerteil 2 und der Dämmschicht T eine dünne Folie 5 anordnen, die zwar schalldurchlässig, jedoch feuchtigkeitsundurchlässig ist. Es kann sich hierbei um eine Aluminiumfolie von weniger als 3 &mgr;&eegr;&igr; Dicke handeln.In order to prevent moisture from entering the insulation layer 3, a thin foil 5 can be arranged between the carrier part 2 and the insulation layer T, which is sound-permeable but moisture-impermeable. This can be an aluminum foil less than 3 μm thick.
Anstelle einer Folie kann man auch eine wasserabweisende Schicht vorsehen z.B. eine Metallschicht. Diese wird durch Prägen, Aufdampfen oder Sprühen aufgebracht. Man kann für die Dämmschicht auch einen wasser- bzw. feuchtigkeitsabweisenden Stoff voreehen, z.B. eine geknitterte Aluminiumfolie in einer oder mehreren Lagen.Instead of a foil, you can also use a water-repellent layer, e.g. a metal layer. This is applied by embossing, vapor deposition or spraying. You can also use a water- or moisture-repellent material for the insulation layer, e.g. a crumpled aluminum foil in one or more layers.
Die Wärme des Abgassystems wird von dem Dämmschild nach dem Gebrauchsmuster in gleichem Maße wie von einem herkömmlichen Dämmschild absorbiert. Jedoch auch das im Abgassystem erzeugte Geräusch wird teilweise in der Dämmschicht absorbiert.The heat of the exhaust system is absorbed by the insulation shield according to the utility model to the same extent as by a conventional insulation shield. However, the noise generated in the exhaust system is also partially absorbed in the insulation layer.
