Abstract

The component with sandwich structure, in particular, for motor vehicle bodywork comprises a distancing layer (11) provided with cutouts (12) which are distributed over its area. These cutouts serve for spot attachment of the cover layer (13) by means of an adhesive, in particular, a melt adhesive (15) directly to the base sheet (10) in such a way that the cover layer and the base sheet are vibrationally decoup-led from one another. Also claimed is a method for producing such a component with sandwich structure.

Description

Die Erfindung bezieht sich auf ein Bauteil nach dem Oberbegriff des Patentanspruchs 1 und auf ein Verfahren nach dem Oberbegriff des Patentanspruchs 11.The invention relates to a component according to the preamble of patent claim 1 and to a method according to the preamble of claim 11.

Bei bekannten Bauteilen der vorbezeichneten Art, in Kraftfahrzeugen als sogenannte Entdröhnung verwendet, besteht das Problem, daß sich Schwingungen des Basisblechs auf die - z. B. aus Aluminiumblech gefertigte - Deckschicht übertragen, somit diese zu entsprechenden Schwingungen anregen.In known components of the aforementioned type, in motor vehicles as so-called When using the deadening, there is the problem that there are vibrations of the base plate on the - z. B. made of aluminum sheet - transfer top layer, so this too stimulate corresponding vibrations.

Aufgabe der Erfindung ist es, eine direkte Anregung der Deckschicht durch das Basisblech zu vermeiden.The object of the invention is a direct excitation of the cover layer by the Avoid base plate.

Gemäß der Erfindung wird die Aufgabe bei einem Bauteil und einem Verfahren der eingangs bezeichneten Gattung durch die kennzeichnenden Merkmale des Patentanspruchs 1 bzw. der Patentansprüche 11 oder 12 gelöst.According to the invention, the object in a component and a method of initially designated genus by the characterizing features of the Claim 1 or claims 11 or 12 solved.

Vorteilhafte Ausgestaltungen des gegenständlichen Teils der Erfindung können den Patentansprüchen 2-10 entnommen werden.Advantageous refinements of the subject part of the invention can Claims 2-10 are taken.

Bei der erfindungsgemäßen punktuellen Verklebung der Deckschicht mit dem Basisblech handelt es sich um eine entkoppelnde Verklebung. Hierbei geht es nicht darum, eine akustische Entkopplung des gesamten Bauteils, also der gesamten "Entdröhnung" zu bewirken. Entkoppelt wird vielmehr nur die Deckschicht, wodurch ein - andernfalls gegebener - schwingungstechnischer Kurzschluß vermieden wird.In the punctual gluing of the cover layer according to the invention with the The base plate is a decoupling glue. This is not possible therefore, an acoustic decoupling of the entire component, i.e. the entire To effect "deadening". Rather, only the cover layer is decoupled, which results in a - otherwise given - vibration short circuit is avoided.

In der Zeichnung sind zwei Ausführungsbeispiele der Erfindung dargestellt, die im folgenden beschrieben werden. Es zeigt - jeweils in vergrößerter Darstellung -:In the drawing, two embodiments of the invention are shown, which in following are described. It shows - each in an enlarged view -:

Fig. 1 eine - ausschnittsweise dargestellte - Ausführungsform eines Bauteils (Entdröhnung für Kraftfahrzeuge), im Vertikalschnitt und Fig. 1 is a - shown in sections - embodiment of a component (noise reduction for motor vehicles), in vertical section and

Fig. 2 eine abgewandelte Variante eines derartigen Bauteils, in Schnittdarstellung entsprechend Fig. 1. FIG. 2 shows a modified variant of such a component, in a sectional view corresponding to FIG. 1.

Die in Fig. 1 und 2 dargestellte Entdröhnung weist ein Basisblech 10 auf, das mit einer Abstandsschicht 11 fest verbunden ist. Die Abstandsschicht 11 besteht aus einem für die genannten Zwecke geeigneten Material, z. B. aus Bitumen-Kunststofffolie. Sie weist - über ihre Fläche verteilt - mehrere Ausnehmungen auf, von denen jeweils eine aus der Zeichnung ersichtlich und mit 12 beziffert ist. Auf der Abstandsschicht 11 liegt eine Deckschicht 13 aus dehnungsfestem Material, z. B. Aluminiumblech. Zwischen der Deckschicht 13 und der Abstandsschicht 11 kann noch eine sogenannte Dissipationsschicht, d. h. eine Verlustschicht (nicht dargestellt) angeordnet sein.The noise reduction shown in FIGS . 1 and 2 has a base plate 10 which is firmly connected to a spacer layer 11 . The spacer layer 11 consists of a material suitable for the purposes mentioned, for. B. from bitumen plastic film. Spread over its surface, it has several recesses, one of which can be seen in the drawing and numbered 12. On the spacer layer 11 is a cover layer 13 made of stretch-resistant material, for. B. aluminum sheet. A so-called dissipation layer, ie a loss layer (not shown) can also be arranged between the cover layer 13 and the spacer layer 11 .

Die wesentliche Besonderheit der dargestellten Entdröhnung besteht darin, daß die Deckschicht 13 im Bereich der Ausnehmungen 12 - gewissermaßen punktuell - in die jeweilige Ausnehmung 12 hineinverprägt und dort mit dem Basisblech 10 verklebt ist. Hierbei bezeichnet 14 die betreffende Verprägung und 15 die eine direkte Verbindung der Teile 10 und 13 bildende Klebeschicht. Erfindungswesentliche Funktion der Klebeschicht 15 ist eine Entkopplung der Deckschicht 13 gegenüber dem Basisblech 10 in schwingungstechnischer Hinsicht. Dadurch läßt sich ein schwingungstechnischer Kurzschluß zwischen Basisblech 10 und Deckschicht 13, d. h. eine direkte Anregung der Deckschicht 13 durch das Basisblech 10, verhindern.The essential peculiarity of the deadening shown is that the cover layer 13 in the area of the recesses 12 - to a certain extent - is stamped into the respective recess 12 and is glued there to the base plate 10 . Here, 14 denotes the embossing in question and 15 the adhesive layer forming a direct connection of the parts 10 and 13 . The function of the adhesive layer 15 that is essential to the invention is a decoupling of the cover layer 13 from the base plate 10 in terms of vibration technology. A vibration short circuit between the base plate 10 and the cover layer 13 , ie a direct excitation of the cover layer 13 by the base plate 10 , can thereby be prevented.

Da die Anbringung der Entdröhnung in einem thermischen Prozess (Gegenkraft) erfolgt, handelt es sich um eine schmelzklebende Entdröhnung. Demgemäß kommt für die Klebeschicht 15 ein Schmelzkleber, z. B. eine Sillikonkleber zum Einsatz. Das verwendete Klebematerial sollte - zur Vermeidung unerwünschter Geräusch- bzw. Wärmebrücken - auch im ausgehärteten Zustand noch eine vergleichsweise weiche Konsistenz besitzen.Since the application of the deadening takes place in a thermal process (counterforce), it is a hot melt adhesive deadening. Accordingly, comes for the adhesive layer 15 is a hot melt adhesive, for example. B. a silicone adhesive for use. In order to avoid unwanted noise or thermal bridges, the adhesive material used should still have a comparatively soft consistency even when cured.

Eine Besonderheit der Ausführungsform nach Fig. 2 besteht darin, daß die Deckschicht 13 im Bereich der Verprägungen 14 jeweils eine Ausnehmung 16 aufweist, die zum Einbringen der Klebeschicht 15 dienen kann. Nach Durchführung der Verklebung kann die Ausnehmung 16 nach außen durch eine Schutzkappe 17, ebenfalls aus entsprechendem Klebematerial, abgedeckt sein.A special feature of the embodiment according to FIG. 2 is that the cover layer 13 in the region of the embossments 14 each has a recess 16 which can be used to introduce the adhesive layer 15 . After the gluing has been carried out, the recess 16 can be covered to the outside by a protective cap 17 , likewise made of appropriate adhesive material.
