Description
Mehrschichtiges schalldämmendes Bauteil für eine aus Blechpreßteilen zUsammengesetzte Karosserie Die Erfindung bezieht sich auf ein mehrschichtiges schalldämmendes Bauteil für eine aus Blechpreßteilen zusammengesetzte Karosserie.Multi-layer sound-absorbing component for one made of pressed sheet metal parts Composite body The invention relates to a multilayer sound-absorbing one Component for a body composed of pressed sheet metal parts.
Aufgabe der Erfindung ist es, mit einfachen Mitteln eine gute Schaildämmung zu erreichen.The object of the invention is to provide good shield insulation with simple means to reach.
Die erfindüngsgemäße lösung besteht darin, daß ein Teppich oder Belag, der an der Fläche, die einem Blechpreßteil zugewendet ist, mit einer Schwerschicht verbunden ist und eine Schale bildet, die auf einer Schicht aus dynamisch weichem Werkstoff, z.B..Schaumstoff an der Karosserie des Fahrzeugs schwimmend gelagert ist. Die auf die Blechpreßteile übertragene, durch die Bewegungen des Antriebsaggregates oder beim Uberrollen der Unebenheiten der Straße erzeugten Schwingungen sind damit nur noch wesentlich gedämpft im Wagenkasteninnern wahrnehmbar Zur Erleichterung der Herstellung kann die Schwerschicht durch Beschichtung des Teppichs mit einem formbaren Werkstoff, z.B.The solution according to the invention is that a carpet or covering, the one on the surface facing a pressed sheet metal part with a heavy layer is connected and forms a shell that rests on a layer of dynamically soft Material, e.g. foam, floating on the body of the vehicle is. The transferred to the pressed sheet metal parts by the movements of the drive unit or vibrations generated when rolling over the bumps in the road are thus only perceptible in the interior of the car body in a substantially subdued form To make things easier The production can be done by coating the carpet with a heavy layer malleable material, e.g.
einem Thermoplast oder einer bitumenhaltigen Masse hergestellt werden, deren Flächengewicht größer als 4 kg/X2 ist.made of a thermoplastic or a bituminous mass will, whose weight per unit area is greater than 4 kg / X2.
Statt vieler kleiner einzelner Teppiche mit eingefaßten Rändern und der sonst üblichen Auskleidung liegen nur zwei in einem einzigen Arbeitsgang verformte Schichten satt aneinander. Durch das satte Anliegen wird auch eine vorzeitige Abnutzung des Teppichs vermieden, die Schalldämpfung verbessert und schließlich eine kostensparende Herstellung der Schale oder Wanne, die von Teppich und der Schwerschicht gebildet wird, in einem Arbeitsgang erreicht.Instead of many small individual carpets with rimmed edges and the otherwise usual lining are only two deformed in a single operation Layers fed up with each other. The full concern also causes premature wear and tear of the carpet is avoided, the soundproofing is improved and finally a cost-saving one Manufacture of the bowl or tub formed by carpet and the heavy layer is achieved in one operation.
Flir die Schicht aus nachgiebigem Werkstoff kann eine Glaswollmatte oder eine Matte aus synthetischen oder natürlichen Fasern verwendet werden. Diese Schicht aus einen dynamisch weichen, mit innerer Dämpfung versehenen Werkstoff verbessert in Verbindung mit der schweren Abdeckschale wesentlich die Schalldämmung und vermindert auch die Vbertragung des Karosseriekörperschalls in den Innenraum.A glass wool mat can be used for the layer of flexible material or a mat made of synthetic or natural fibers can be used. These Layer made of a dynamically soft material provided with internal damping improved in connection with the heavy cover shell, the sound insulation is significantly reduced also the transmission of the body structure-borne noise into the interior.
Aus diesem Grunde soll die Schicht aus nachgiebigem Werkstoff auch einen Abstand von mindestens 10 mm zwischen der Schale und den Blechpreßteilen der Karosserie aufrechterhalten. Die Teppichfläche kann auch nur örtlich beschichtet sein, vorzugsweise im Bereich der Spritzwand, der Radkästen und im Abstellbereich der Füße vor den Vordersitzen. Damit ist eine Vereinfachung geschaffen, weil nicht immer die ganze Teppichfläche zur Schalldämmung herangezogen werden muß.For this reason, the layer of flexible material should also a distance of at least 10 mm between the shell and the pressed sheet metal parts of the Maintain bodywork. The carpet surface can also only be coated locally be, preferably in the area of the bulkhead, the wheel arches and in the parking area the feet in front of the front seats. This creates a simplification because it is not the entire carpet surface must always be used for sound insulation.
In einfacher Weise kann der beschichtete Teppich durch Tiefziehen, Pressen oder dergleichen zu einer-Schale verformt werden. Der Teppich und die Schwerschicht können aber auch unabhängig voneinander zu zwei zueinander passenden Schalen verformt und dann miteinander verklebt werden. Schließlich kann die mit dem Teppich verbundene Schale nicht nur den Wagenkastenboden, sondern auch die Spritzwand und andere Schwingungen übertragende Teile überdecken.In a simple way, the coated carpet can be deep-drawn, Pressing or the like can be deformed into a shell. The carpet and the heavy shift but can also be deformed independently of one another into two matching shells and then glued together. Finally, the carpet can be associated with Shell not only the car body floor, but also the bulkhead and other vibrations Cover transferring parts.
Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung, Fig. 1 eine perspektivische Darstellung des schalenförmigen Bauteils, das sich durch die. Verbindung von Teppich und Schwerschicht ergibt Fig. 2 einen Schnitt II-II durch Fig. 1 mit der Schicht aus dynamisch weichem Werkstoff und dem Blechpreßteil Fig. 3 einen Schnitt längs durch ein Fahrzeug mit dem Bauteil aus Fig. 1 und Fig. 4 eine weitere Ausführungsform des Bauteiiea-. aus Figo ta-.The drawing shows an embodiment of the invention, FIG. 1 a perspective view of the shell-shaped component that extends through the. Connection of carpet and heavy layer gives Fig. 2 a section II-II through Fig. 1 with the layer of dynamically soft material and the pressed sheet metal part Fig. 3 shows a longitudinal section through a vehicle with the component from FIG. 1 and FIG Another embodiment of the component. from Figo ta-.
Der Wägenkastenbde 1 besteht aus den Bodenblechen 2. Auf den Bodenblechen 2 ist eine dynamisch weiche Schicht. 3 angeordnet. Für die Schicht 3 kann eine Glaswollmatte oder eine Matte aus synthetischen oder natürlichen Fasern verwendet werden. Auf der Schicht 3 schwimmt die Schale 4, die aus einem Teppich oder Belag 5 und einer Schwerschicht 6 besteht, für deren Herstellung ein Thermoplast oder eine bitumenhaltige Masse geeignet ist, deren Flächengewicht größer als 4 kg/m2 ist.The weighing box floor 1 consists of the floor panels 2. On the floor panels 2 is a dynamically soft layer. 3 arranged. A glass wool mat can be used for layer 3 or a mat made of synthetic or natural fibers is used will. The shell 4, which consists of a carpet or covering, floats on the layer 3 5 and a heavy layer 6, for the production of which a thermoplastic or a bituminous compound is suitable, the weight per unit area of which is greater than 4 kg / m2 is.
Die mit dem Teppich 5 verbundene Schwerschicht 6 überdeckt auch andere Blechpreßteile, z.B. die Spritzwand 7. Der Abstand zwischen der Schale 4 und den Blechteilen z.B. 2, 7 soll mindestens 10 mm betragen und kann örtlich unterschritten werden, jedoch nicht mehr als 20,' der zur Schalldämpfung herangezogenen Fläche.The heavy layer 6 connected to the carpet 5 also covers others Pressed sheet metal parts, e.g. the bulkhead 7. The distance between the shell 4 and the Sheet metal parts e.g. 2, 7 should be at least 10 mm and can be below this locally but not more than 20 'of the area used for soundproofing.
Die Fläche des Teppichs 5 kann auch, wie in Fig. 4 dargestellt, nur örtlich beschichtet sein. Die Schwerschicht 6 und dementsprechend die dynamisch weiche Schicht 3 ist dann beispielsweise nur im Bereich 7 der Spritzwand und im Bereich 9 der Radkästen und im Abstellbereich 10 der Füße vor den Vordersitzen li angebracht. An den übrigen,für die Schalldämmung weniger wichtigen Stellen, liegt der Teppich unmittelbar auf den Blechpreßteilen 2 auf.The surface of the carpet 5 can also, as shown in FIG. 4, only be coated locally. The heavy layer 6 and accordingly the dynamic soft layer 3 is then, for example, only in area 7 of the bulkhead and in the Area 9 of the wheel arches and left in the parking area 10 of the feet in front of the front seats appropriate. At the other points, which are less important for sound insulation, the carpet directly on the pressed sheet metal parts 2.
