Abstract

The seal is esp. for use in an IC engine. It has a band type insert surrounded by an elastomeric material. The insert has holes for mounting bolts, and lugs in the region of the bolts extending sideways and folding along a line on the insert. This creates a local thickness around the hole and acts as a compression limiter. The fold line (5) runs perpendicular to the insert (4), so that when folded at least three times the material thickness results. USE/ADVANTAGE - Simplified mfr. of sealing device used in IC engine with reduced mfr. costs.

Description

Die Erfindung betrifft eine Dichtung, insbesondere für Brennkraftmaschinen, mit einer bandförmigen Einlage, die von elastomerem Material umschlossen ist, wobei die Einlage Löcher zur Aufnahme von Schrauben und im Bereich der Löcher seitwärts sich erstreckende Lappen aufweist, die entlang einer Faltlinie auf die Einlage umklappbar sind, so daß im Bereich der Löcher eine als Verpressungsbegrenzer fungierende Verdickung gebildet ist.The invention relates to a seal, in particular for Internal combustion engines, with a band-shaped insert, which is enclosed by elastomeric material, wherein the insert holes for receiving screws and in Area of the holes flaps extending sideways having along a fold line on the insert are foldable, so that in the area of the holes as Compression limiter acting thickening formed is.

Gattungsgemäße Dichtungen finden Anwendung bei der Abdichtung zwischen Motorblock und Ölwanne oder als Ventildeckeldichtung bei Brennkraftmaschinen.Generic seals are used in the Sealing between engine block and oil pan or as Valve cover gasket for internal combustion engines.

Zur Abdichtung der Trennfuge dieser Bauteile wird die Dichtung über zahlreiche, über den Umfang verteilt angeordnete Schrauben verpreßt. Um eine gleichmäßige Dichtwirkung über den gesamten Umfang zu erzeugen, werden sogenannte Verpressungsbegrenzer eingesetzt. Diese sorgen dafür, daß beim Festziehen der Schrauben das elastomere Material eine gleichmäßige Verspannung erhält.To seal the parting line of these components, the Seal over numerous, distributed over the circumference arranged screws pressed. To be even To create a sealing effect over the entire circumference, so-called compression limiters are used. These ensure that when tightening the screws the elastomeric material has an even tension receives.

Die EP 0 455 579 offenbart eine gattungsgemäße Dichtung, bestehend aus einer Verstärkungseinlage, die mit elastomerem Material umschlossen ist. Die Verstärkungseinlage besteht aus einem Metallband, dessen Enden miteinander verschweißt sind. Im Bereich der Schrauben sind seitwärts gerichtete Lappen angeordnet, die entlang einer Faltlinie auf das Metallband geklappt werden, so daß im Bereich der Löcher eine doppelte Metallbandeinlage gebildet ist.EP 0 455 579 discloses a generic one Seal consisting of a reinforcing insert, the is enclosed with elastomeric material. The  Reinforcement insert consists of a metal band, the ends of which are welded together. In the area the screws are rags directed sideways arranged along a fold line on the Metal band can be folded so that in the area of Holes a double metal tape insert is formed.

Die Herstellung des genannten Metallbandes erfolgt durch Stanzen, so daß aufgrund der seitlich angeordneten Lappen ein hoher Prozentsatz Abfall des Ausgangsmaterials anfällt.The production of the metal strip mentioned takes place by punching, so that due to the sideways arranged rags a high percentage of the waste Starting material arises.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Dichtung im Hinblick auf die Herstellung zu vereinfachen und gleichzeitig die Herstellungskosten zu senken.The invention has for its object a generic seal with regard to the Simplify manufacturing while maintaining the Reduce manufacturing costs.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Faltlinie quer zur Einlage verläuft, so daß beim Falten der Einlage mindestens eine dreifache Materialverdickung gebildet ist. Auf diese Weise können die seitlich hervorstehenden Lappen entfallen, wodurch beim Stanzen der Einlage weniger Abfall anfällt.This object is achieved in that the fold line runs transversely to the insert, so that when Fold the insert at least three times Material thickening is formed. In this way the tabs protruding from the side can be omitted, which means less waste when punching the insert arises.

Vorzugsweise bestehen die Einlagen aus Blech. Die Umfangskontur des Bleches ist einem weiteren Gedanken der Erfindung gemäß durch Streckbiegen hergestellt. Bei diesem Verfahren wird Blechabfall fast vollständig vermieden, da die Kontur des Bleches durch Strecken und Stauchen eines bandförmigen Halbzeuges erzeugt wird. Die Endbereiche der auf diese Weise erzeugten Einlage werden kraftschlüssig miteinander verbunden.The inserts preferably consist of sheet metal. The Circumferential contour of the sheet is another thought made according to the invention by stretch bending. With this process, sheet metal waste becomes almost complete avoided because the contour of the sheet by stretching  and upsetting a band-shaped semi-finished product becomes. The end areas of the generated in this way Inlays are non-positively connected to each other.

Die Erfindung ist in der Zeichnung anhand eines Ausführungsbeispiels dargestellt und wird im folgenden näher erläutert. Es zeigenThe invention is in the drawing based on a Embodiment shown and is in the following explained in more detail. Show it

Fig. 1 Draufsicht einer erfindungsgemäßen Dichtung, Fig. 1 a plan view of a gasket according to the invention,

Fig. 2 Ausschnitt gemäß Linie II-II. Fig. 2 section along line II-II.

Die Fig. 1 zeigt eine erfindungsgemäße Dichtung (1), die als Ölwannendichtung bei Kraftfahrzeugen eingesetzt wird. Die Dichtung (1) weist mehrere über den Umfang verteilt angeordnete Löcher (2) zur Aufnahme von Befestigungsschrauben auf, um die Dichtung (1) zwischen den abzudichtenden Bauteilen axial verpressen zu können. Um die aus elastomerem Material bestehende Dichtung (1) zu versteifen, ist im Innern der Dichtung (1) eine Verstärkungseinlage (4) aus bandförmigen Blechstreifen (Fig. 2) vorgesehen. Im Bereich der Löcher (2) ist die Einlage (4) entlang einer quer zur Einlage (4) verlaufenden Faltlinie (5, 5′) gefaltet, derart, daß eine dreifache Materialverdickung erzeugt wird. Diese Materialverdickung dient als Verpressungsbegrenzung (9) des elastomeren Materials (6) beim Anziehen der Befestigungsschrauben (nicht gezeichnet). Die als Verpressungsbegrenzung (9) wirkende Faltung ist so ausgelegt, daß die mittlere Lage (7) etwa in der Horizontalebene der Verstärkungseinlage (4) liegt. Fig. 1 shows a seal ( 1 ) according to the invention, which is used as an oil pan seal in motor vehicles. The seal ( 1 ) has a plurality of holes ( 2 ) arranged around the circumference for receiving fastening screws in order to be able to axially press the seal ( 1 ) between the components to be sealed. To the existing elastomeric material to stiffen seal (1), in the interior of the seal (1) is a reinforcing insert provided (4) of the band-shaped sheet metal strips (Fig. 2). In the area of the holes ( 2 ), the insert ( 4 ) is folded along a fold line ( 5 , 5 ') running transversely to the insert ( 4 ) in such a way that a threefold thickening of the material is produced. This thickening of the material serves as a compression limitation ( 9 ) of the elastomeric material ( 6 ) when the fastening screws are tightened (not shown). The fold acting as a compression limitation ( 9 ) is designed so that the middle layer ( 7 ) lies approximately in the horizontal plane of the reinforcement insert ( 4 ).

Um das abfallträchtige Stanzverfahren zu vermeiden, ist die Einlage (4) durch Streckbiegen eines bandförmigen Bleches in die rechteckförmige Kontur gemäß Fig. 1 geformt worden. Die Blechenden werden anschließend kraftschlüssig miteinander verbunden, beispielsweise durch Schweißen (8).In order to avoid the waste-prone stamping process, the insert ( 4 ) has been formed by stretch bending a band-shaped sheet into the rectangular contour according to FIG. 1. The sheet ends are then non-positively connected to one another, for example by welding ( 8 ).
