Description

Beschreibung Bauteil zur Geräuschdämmung. Description Component for sound insulation.

Die Erfindung betrifft ein Bauteil zur Geräuschdämmung, insbesondere zur Anwendung im Fahrzeugbau.The invention relates to a component for sound insulation, in particular for use in vehicle construction.

Es ist bekannt, daß im Kraftfahrzeugbau Antriebsaggregate teilweise mit Gehäusen versehen sind, die die durch das Aggregat erzeugten Geräusche reduzieren. Derartige Bauteile sind bekannt aus dem Getriebe- und Motorenbau, wobei z. B. Getriebegehäuse geräuschdämmend aufgebaut sind. Die Geräuschdämmung wird nach dem Stand der Technik dadurch realisiert, daß das Gehäuse aus zwei metallischen Schichten, also beispielsweise Blechen, besteht, die durch eine Kunststoffschicht miteinander verbunden sind. D. h., daß ein derartiges Gehäuse im wesentlichen dreischichtig ausgebildet ist. Nachteilig an einem derartigen Gehäuse ist, daß aufgrundIt is known that in motor vehicle construction, drive units are sometimes provided with housings that reduce the noise generated by the unit. Such components are known from gearbox and engine construction, where gearbox housings, for example, are designed to be noise-insulating. According to the state of the art, noise insulation is achieved by the housing being made of two metallic layers, for example sheet metal, which are connected to one another by a plastic layer. This means that such a housing is essentially made of three layers. The disadvantage of such a housing is that, due to

der Kunststoffzwischenschicht derartige Bauteile nur dort eingesetzt werden können, wo Temperaturen oberhalb von 130° bis 140° nicht auftreten, da ansonsten die Kunststoffzwischenschicht abschmilzt, wobei dann in der Folge die Geräuschdämmung stark herabgesetzt ist.Due to the plastic intermediate layer, such components can only be used where temperatures above 130° to 140° do not occur, otherwise the plastic intermediate layer will melt, which will then significantly reduce the sound insulation.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Bauteil zur Geräuschdämmung zu schaffen, das auch bei Aggregaten einsetzbar ist, die im hohen Temperaturbereich arbeiten.The invention is therefore based on the object of creating a component for noise insulation that can also be used in units that operate in the high temperature range.

Die Aufgabe wird erfinderungsgemäß durch mindestens zwei übereinander angeordnete metallische Schichten, beispielsweise Bleche, gelöst, die insbesondere eine unterschiedliche Stärke aufweisen. Insbesondere bei Schichten von unterschiedlicher Stärke hat sich gezeigt, daß hiermit eine Geräuschdämmung erreicht werden kann, die auch mit dem aus dem Stand der Technik bekannten dreischichtig aufgebauten Bauteil erreichbar ist. Erklärbar ist dies dadurch, daß die beiden Schichten aufgrund der unterschiedlichen Dicke jeweils eine andere Eigenfrequenz aufweisen, die zu einer Vernichtung der entstehenden Frequenzen führt. Es hat sich weiterhin als vorteilhaft herausgestellt, wenn mindestens eine der beiden Schichten eine Beschichtung, beispielsweise aus Aluminium, aufweist, die auf der der anderen Schicht zugewandten Seite aufgebracht ist. Die beiden Schichten sind hierbei unmittelbar, beispielsweise durch Druckfügen, miteinander verbunden. Unter Druckfügen versteht man ein Verstemmen der Bauteile, wobei das Druckfügen den Vorteil hat, daß hierbei eine Beschädigung der Oberflächen weitgehend vermieden wird. Kann eine Beschädigung der Oberflächen vermieden werden, so besteht auch keine Gefahr der Korrosion zwischen den beiden das Bauteil bildenden Schichten.According to the invention, the problem is solved by at least two metal layers, for example sheets, arranged one above the other, which in particular have a different thickness. In particular with layers of different thicknesses, it has been shown that this can achieve a level of noise insulation that can also be achieved with the three-layer component known from the prior art. This can be explained by the fact that the two layers each have a different natural frequency due to the different thickness, which leads to the elimination of the resulting frequencies. It has also proven to be advantageous if at least one of the two layers has a coating, for example made of aluminum, which is applied to the side facing the other layer. The two layers are connected to one another directly, for example by pressure joining. Pressure joining is understood to mean caulking the components, whereby pressure joining has the advantage that damage to the surfaces is largely avoided. If damage to the surfaces can be avoided, there is also no risk of corrosion between the two layers forming the component.
