Description

Die Erfindung betrifft ein Abschirmelement für Kraftfahrzeuge.The The invention relates to a shielding element for motor vehicles.

In der EP-A 0 806 555 wird ein Hitzeschild, insbesondere zur Abschirmung Abgas führender Teile in Kraftfahrzeugen beschrieben, mit mindestens einer zwischen zwei Decklagen angeordneten metallischen Dämmlage, wobei selbige von einem mittels einer Vielzahl von Durchstoßungen strukturierten Blechteil oder einer Folie gebildet ist. Die Decklagen sind als unstrukturierte Blechteile ausgebildet. Die Durchstoßungen der Dämmlage bilden Durchstoßungsgrate auf gegenüberliegenden Seiten der Dämmlage, wobei die Dämmlage mit den Decklagen verpresst ist. Die Durchstoßungsgrate können geschlitzt, zacken- oder zungenförmig ausgebildet und nach außen abgebogen sein. Die Grate bilden hierbei punktförmige Wärmebrücken mit den Decklagen, über die nur ein sehr geringer Wärmeaustausch zwischen der heißeren inneren Decklage und der äußeren Decklage erfolgt.In EP-A 0 806 555 is a heat shield, in particular for shielding Exhaust leading Parts described in motor vehicles, with at least one between two cover layers arranged metallic Dämmlage, where selbige of a by means of a plurality of perforations structured sheet metal part or a film is formed. The cover layers are considered unstructured Sheet metal parts formed. The punctures form the Dämmlage Durchstoßungsgrate on opposite Sides of the insulation layer, the insulation layer is pressed with the cover layers. The piercing burrs can be slotted, serrated or tongue-shaped trained and outward be bent. The burrs form punctiform thermal bridges with the cover layers over which only a very small heat exchange between the hotter ones inner cover layer and the outer cover layer he follows.

Durch das DE-Gbm 91 07 484 ist ein Hitzeschild zur Abschirmung von Abgas führenden Teilen an einem Kraftfahrzeug gegenüber der Bodengruppe des Kraftfahrzeugs bekannt geworden, mit einem die Schildvorderseite bildenden Trägerblech aus Aluminium, das an seiner Rückseite eine Isolierschicht trägt. Die Isolierschicht weist eine Einlage aus einem regelmäßigen Maschenwerk und mindestens eine Aluminiumdeckfolie auf, wobei die Einlage mit einer Wellung plissiert ist.By DE-Gbm 91 07 484 is a heat shield for shielding exhaust gas leading Sharing on a motor vehicle relative to the bottom group of the motor vehicle become known, with a shield front side forming carrier sheet made of aluminum, on the back carries an insulating layer. The insulating layer has an insert from a regular mesh and at least one aluminum cover sheet, wherein the insert with a corrugation is pleated.

Der Erfindung liegt die Aufgabe zugrunde, ein Abschirmelement für Kraftfahrzeuge bereitzustellen, das einfach im Aufbau ist, kostengünstig und ohne manuelle Handarbeitsgänge hergestellt sowie einfach montiert werden kann und darüber hinaus eine gute Wärme- und/oder Schallisolation ermöglicht.Of the Invention is based on the object, a shielding for motor vehicles to provide that is simple in construction, inexpensive and without manual handicrafts can be manufactured as well as easily assembled and beyond that good heat and / or soundproofing.

Diese Aufgabe wird gelöst durch ein Abschirmelement für Kraftfahrzeuge, bestehend aus mindestens zwei beabstandeten, miteinander in Wirkverbindung stehenden metallischen Lagen etwa gleicher Materialdicke, zwischen denen mindestens eine Lage eines Streckmetalls unter definierter Vorspannung eingebracht ist.These Task is solved by a shielding element for Motor vehicles consisting of at least two spaced apart, with each other in actively connected metallic layers of approximately the same material thickness, between which at least one layer of an expanded metal under defined Preload is introduced.

Vorteilhafte Weiterbildungen des erfindungsgemäßen Abschirmelementes sind den Unteransprüchen zu entnehmen.advantageous Further developments of the shielding element according to the invention are the dependent claims refer to.

Das Abschirmelement kann hierbei als Hitzeschild oder als Schallschutzelement im Bereich eines Kraftfahrzeuges eingesetzt werden. Das Abschirmelement besteht aus mehreren Lagen, die einen Sandwichaufbau mit Luftpolstern ergeben. Die beiden äußeren Lagen bestehen aus Aluminium, Edelstahl oder Al-beschichteten Stählen. Die zwischen einzelnen Lagen vorgesehene innere Lage besteht aus einem Streckmetall. Die mindestens drei beschriebenen Lagen können gleichzeitig von übereinander angeordneten Coils aufeinander abgewickelt und direkt ohne Zusatzarbeitsgang in ein Werkzeug zur Weiterverarbeitung bewegt werden. Hierbei ist es möglich, den Abstand und somit die Luftpolstermenge zwischen den zumindest beiden äußeren Lagen durch den Einsatz von unterschiedlich dickem Streckmetall zu variieren. Durch den in Folge ablaufenden Montage- und Verbindungsprozess der Lagen werden selbige unter Vorspannung miteinander verbunden, so dass ein Klappern des Streckmetalls zwischen den Lagen verhindert wird.The Shielding element can in this case as a heat shield or as a soundproofing element be used in the field of a motor vehicle. The shielding element consists of several layers that have a sandwich construction with air cushions result. The two outer layers consist of aluminum, stainless steel or Al-coated steels. The Between inner layers provided inner layer consists of a Expanded metal. The at least three layers described can simultaneously from one another arranged coils processed to each other and directly without additional work be moved into a tool for further processing. Here is it possible the Distance and thus the amount of air cushion between the at least two outer layers to vary through the use of different thickness expanded metal. Due to the sequential assembly and connection process of Layers are themselves connected under bias, so that a rattling of the expanded metal between the layers is prevented.

Bei einer nachfolgenden, bedarfsweise dreidimensionalen Formgebung des beschriebenen Mehrlagen-Sandwiches, dient das Streckmetall zwischen den äußeren Lagen als Abstandshalter und verhindert ein Zusammenpressen der äußeren Lagen und somit die Reduzierung der vorgegebenen Luftpolster.at a subsequent, if necessary, three-dimensional shape of the described multilayer sandwiches, the expanded metal serves between the outer layers as a spacer and prevents compression of the outer layers and thus the reduction of the given air cushion.

Durch unterschiedliche Dicken der zwischen den äußeren Lagen vorgesehenen mittleren Streckmetalllage kann der Abstand zwischen den äußeren Lagen eingestellt werden. Somit ergibt sich die Möglichkeit, die Isolationswirkung des Abschirmelementes durch Vergrößerung des Außenlagenabstandes zu erhöhen, indem auch die Größe der Luftpolster erhöht wird.By different thicknesses of the provided between the outer layers middle Expanded metal layer, the distance between the outer layers can be adjusted. This results in the possibility the insulating effect of the shielding by enlargement of the Outward distance to increase, by including the size of the air cushion elevated becomes.

Durch Einsatz von Aluminium oder beschichtetem Stahl für den Sandwichaufbau stellt sich als weiterer Vorteil eine optimale Gesamtrecyclingfähigkeit ein.By Use of aluminum or coated steel for sandwich construction provides as an additional advantage an optimal total recyclability one.

1 Querschnitt durch ein als Hitzeschild ausgebildetes Abschirmelement; 1 Cross section through a trained as a heat shield shielding;

2 Draufsicht auf ein Streckmetall. 2 Top view of an expanded metal.

1 zeigt als Prinzipskizze im Querschnitt ein in diesem Beispiel als Hitzeschild ausgebildetes Abschirmelement 1, wie es beispielsweise im Abgasstrang eines Kraftfahrzeuges eingesetzt werden kann. Das Abschirmelement 1 beinhaltet zwei äußere Lagen 2, 3, die in diesem Beispiel aus Edelstahl bestehen und gleiche Materialdicke d haben sollen. Zwischen den äußeren Lagen 2, 3 erstreckt sich eine Lage
eines Streckmetalls 4, das unter definierter Vorspannung zwischen den äußeren Lagen 2, 3 des Abschirmelementes 1 positioniert ist. Die einzelnen Kammern 5 des Streckmetalls 4 bilden zwischen den einander zugewandeten glatten Stirnflächen 6, 7 der äußeren Lagen 2, 3 Luftpolster, wobei die Luftpolstermenge durch Variation des Abstandes h der beiden Stirnflächen 6, 7 in Abhängigkeit vom Einsatzfall vorgebbar ist. 1 shows a schematic diagram in cross section a trained in this example as a heat shield shielding 1 , as it can be used for example in the exhaust system of a motor vehicle. The shielding element 1 includes two outer layers 2 . 3 , which in this example is made of stainless steel exist and should have the same material thickness d. Between the outer layers 2 . 3 extends a location
an expanded metal 4 under defined pretension between the outer layers 2 . 3 the shielding element 1 is positioned. The individual chambers 5 of the expanded metal 4 form between the mutually facing smooth faces 6 . 7 the outer layers 2 . 3 Air cushion, wherein the amount of air cushion by varying the distance h of the two end faces 6 . 7 can be specified depending on the application.

Alternativ besteht die Möglichkeit, die äußeren Lagen 2, 3 aus Aluminiumblechen oder aus mit Aluminium beschichteten Stahlblechen zu erzeugen. Die in diesem Beispiel vorgesehenen drei Lagen 2, 3, 4 können gleichzeitig von übereinander angeordneten Coils aufeinander abgewickelt werden und direkt, ohne Zusatzarbeitsgang in ein nachgeschaltetes Werkzeug zur Weiterverarbeitung vorgeschoben werden. Durch den in Folge ablaufenden Montage- und Verbindungsprozess der Lagen 2, 3, 4 werden selbige unter definierter Vorspannung miteinander verbunden, so dass ein Klappern des Streckmetalls 4 zwischen den Lagen 2, 3 verhindert wird. Bei einer sich anschließenden nachfolgenden dreidimensionalen Formgebung des beschriebenen Mehrlagen-Sandwiches dient das Streckmetall 4 zwischen den beiden äußeren Lagen 2, 3 als Abstandshalter und verhindert ein Zusammenpressen der äußeren Lagen 2, 3 und somit die Reduzierung der in den Kammern 5 vorgesehenen Luftpolster. In diesem Beispiel sollen die Endbereiche 8, 9 der äußeren Lagen 2, 3 durch Umbördeln miteinander verbunden sein, wobei auch hier alternative Verbindungsmethoden, wie beispielsweise Clinchen, denkbar sind.Alternatively, there is the possibility of the outer layers 2 . 3 aluminum sheets or aluminum-coated steel sheets. The three layers provided in this example 2 . 3 . 4 can be unwound simultaneously by superimposed coils and be advanced directly, without additional work in a downstream tool for further processing. Due to the sequential assembly and connection process of the layers 2 . 3 . 4 the same are connected to each other under defined bias, so that a rattling of the expanded metal 4 between the layers 2 . 3 is prevented. In a subsequent subsequent three-dimensional shaping of the multilayer sandwich described, the expanded metal is used 4 between the two outer layers 2 . 3 as a spacer and prevents compression of the outer layers 2 . 3 and thus the reduction in the chambers 5 provided air cushion. In this example, the end regions 8th . 9 the outer layers 2 . 3 be connected by crimping, where also alternative connection methods, such as clinching, are conceivable.

Die Maschen 10 werden gebildet durch Stege 11, wobei im Kreuzungspunkt zwischen vier aneinander stoßenden Stegen 11 Knotenpunkte 12 gebildet werden. Das Streckmetall 4 hat eine vorgebbare Höhe h, wie sie in 1 angesprochen ist. Durch Variation der Maschenweite, der Maschenlänge, der Stegdicke sowie der Stegbreite können unterschiedlichste technische Anforderungen im Bereich eines Kraftfahrzeuges bedient werden. 2 shows in plan view the in 1 used expanded metal 4 , Visible are the latticed structure of the expanded metal 4 , being a variety of stitches 10 be formed. The stitches 10 are formed by webs 11 , wherein at the intersection between four abutting webs 11 hubs 12 be formed. The expanded metal 4 has a predefinable height h, as in 1 is addressed.
