Abstract

The device has a recess (3) and an insert (4) fitting into the recess. The insert exhibits a circulating flange-shaped impressed part (5) at edges. A geometrical contour of the edges of the insert is complementarily adapted to the form of the recess. The impressed part stays approximately perpendicularly to a surface of the recess. A circulating flange-shaped impressed part (6) complementary to the impressed part (5) of the insert is arranged at the edges of the recess of a front wall (1).

Description

Die Erfindung betrifft eine Fahrzeugstirnwand, die mit als Durchbrüchen ausgestalteten Durchtrittsbereichen versehen ist, um Aggregate im Motorraum mit den zugeordneten Steuer- und Funktionselementen im Fahrgastraum zu verbinden und zusätzliche Funktionen in die Fahrzeugstirnwand zu integrieren.The The invention relates to a vehicle front wall, which with as breakthroughs equipped passage areas is provided to aggregates in the engine compartment with the associated control and functional elements in the passenger compartment to connect and additional functions in the vehicle's front wall to integrate.

Die DE 198 49 398 A1 zeigt eine Fahrzeugstirnwand mit mehreren Durchtrittsbereichen, wobei die Durchbrüche mittels mehrerer mit Öffnungen versehener Einsätze abgedeckt werden und die Einsätze aus mindestens zwei Teilstücken bestehen, welche sowohl gegen die Stirnwand wie auch untereinander gehalten werden. In den Stoßbereichen zwischen den Einsätzen greifen Randstege und komplementäre Randöffnungen ineinander.The DE 198 49 398 A1 shows a vehicle end wall having a plurality of passage areas, wherein the openings are covered by means of a plurality of apertured inserts and the inserts consist of at least two sections, which are held both against the end wall as well as with each other. In the abutting areas between the inserts, edge webs and complementary edge openings engage each other.

Die DE 195 24 175 A1 zeigt eine Stirnwand für ein Kraftfahrzeug, die mit einer Karosserietragstruktur des Kraftfahrzeugs verbindbar ist, und die Durchbrüche für die Hindurchführung oder Aufnahme von Funktionseinrichtungen des Kraftfahrzeugs in der Stirnwand aufweist. Die Durchbrüche sind korrespondierend paarweise und symmetrisch zu einer vertikalen Mittellängsebene des Kraftfahrzeugs ausgebildet. Die Außenkontur der in die Stirnwand eingesetzten Bauteile oder Module ist an die geometrische Struktur der Stirnwandöffnungen angepasst.The DE 195 24 175 A1 shows an end wall for a motor vehicle, which is connectable to a body support structure of the motor vehicle, and has the openings for the passage or reception of functional devices of the motor vehicle in the end wall. The apertures are correspondingly formed in pairs and symmetrically to a vertical central longitudinal plane of the motor vehicle. The outer contour of the components or modules inserted in the end wall is adapted to the geometric structure of the end wall openings.

Die vorliegende Erfindung beschäftigt sich mit dem Problem, einen weiteren Durchbruch für die Stirnwand eines Kraftfahrzeugs in einem schon mit vielen verschiedenen Bauteilen und Durchbrüchen belegten Stirnwandbereich so anzuordnen, dass die Stirnwand ihre Biege- und Torsionssteifigkeit möglichst wenig einbüßt. Dabei ist besonders in dem bei der Endmontage schwierig zugänglichen Bereich des Lenkungsdurchtritts auf eine montagefreundliche Zugänglichkeit zu achten. Zur besseren Montierbarkeit der Einsätze sollten diese außerhalb der Endmontage als vormontierte Module komplettiert werden.The The present invention addresses the problem of another breakthrough for the front wall of a motor vehicle in an already with many different components and breakthroughs occupied Arrange the end wall area so that the end wall of their bending and Torsional stiffness as little as possible loses. It is particularly difficult to access in the final assembly Area of the steering passage on a mounting-friendly accessibility to pay attention. For better mountability of the inserts should these outside the final assembly as pre-assembled modules be completed.

Die Erfindung beruht auf dem allgemeinen Gedanken, dass eine Bauteilgruppe wie eine Stirnwand eines Fahrzeugkarosseriekörpers nur dann ihre Biege- und Torsionssteifigkeit erzielen und behalten kann, wenn auch die in ihr integrierten Einsätze einerseits eine Eigensteifigkeit aufweisen und andererseits steif in den Durchbrüchen der Stirnwand verankert sind.The The invention is based on the general idea that a group of components as an end wall of a vehicle body body only then achieve and maintain their bending and torsional rigidity although the inserts integrated into it, on the one hand, Have inherent rigidity and on the other hand stiff in the openings the end wall are anchored.

Dabei werden die in den eingangs erwähnten Schriften angeführten Einsätze für die Durchbrüche geometrisch so gestaltet, dass ihre Biege- und Torsionssteifigkeit möglichst hoch ist.there are mentioned in the aforementioned writings Inserts for breakthroughs geometric designed so that their bending and torsional stiffness possible is high.

In einer vorteilhaften Ausführungsform sind an den Rändern des Einsatzes umlaufende kragenförmige Verprägungen angeordnet, welche die Biege- und Torsionssteifigkeit erhöhen.In an advantageous embodiment are at the edges the use of circumferential collar-shaped stampings arranged, which increase the bending and torsional rigidity.

In einer weiteren vorteilhaften Ausführungsform ist die Kontur der Ränder des Einsatzes an die geometrische Form der Durchbrüche der Stirnwand möglichst genau angepasst, damit eine hohe Abdichtung der Paarung Einsatz und Durchbruch gegen Staub, Flüssigkeiten und Lärm gewährleistet werden kann.In A further advantageous embodiment is the contour the edges of the insert to the geometric shape of the openings the front wall adjusted as accurately as possible, thus a high Sealing the mating insert and breakthrough against dust, liquids and noise can be guaranteed.

Um die Biege- und Torsionssteifigkeit des Bauteils zu maximieren, stehen diese Verprägungen senkrecht zur Oberfläche des Einsatzes; somit können auf den Einsatz wirkende Biegekräfte aufgenommen und auch die Verprägungen gleichmäßig verteilt werden, ohne dass sich der Einsatz weit verformt.Around to maximize the flexural and torsional rigidity of the component these stampings perpendicular to the surface of insert; thus acting on the insert bending forces recorded and also the stampings evenly be distributed without the use deformed far.

In einer weiteren vorteilhaften Ausführungsform sind auch an den Rändern der Durchbrüche der Stirnwand kragenförmige Verprägungen angeordnet. Somit weisen einerseits die Durchbrüche der Stirnwand alleine schon eine hohe Biege- und Torsionssteifigkeit auf. Im komplementären Zusammenspiel der Paarung Einsatz und Durchbruch ergeben die dann aneinander liegenden und paarwiese fest verbundenen Verprägungen eine besonders hohe Biege- und Torsionssteifigkeit.In a further advantageous embodiment are also collar-shaped at the edges of the apertures of the front wall Deformations arranged. Thus, on the one hand, the breakthroughs The front wall alone already a high bending and torsional rigidity on. In the complementary interaction of mating use and breakthrough then result in each other and paarwiese firmly connected embossings a particularly high bending and torsional stiffness.
