Abstract

The plate of sheet metal (6) is fitted with centering and locating components (5) and can thus be joined to a flange (8) without fear of loss or escape. The specified components are preferably integrated into the plate and are composed of spring clips arranged near a screw hole (10) in this plate (6). Clip (5) engages a flange opening (7) and can be repeated round the plate to hold the seal to the flange. In a variant, a spring clip engages the screw hole so that rim and hole clips can be combined. In this variant, an angled end piece engaging the screw hole performs the centering function, using the rim clips to secure the seal to the flange concerned.

Description

Die Erfindung betrifft eine Flachdichtung, bestehend aus einer oder mehreren, zu einem Laminat verbundenen Metallblechplatten und mindestens einer Durchgangsöffnung, insbesondere zur Abdichtung von Abgasrohren in Verbrennungskraftmaschinen.The invention relates to a flat gasket consisting of one or more to one Laminated sheet metal plates and at least one through opening, in particular for sealing exhaust pipes in internal combustion engines.

Die in der Praxis verwendeten Flachdichtungen für Abgasrohre bestehen üblicherweise aus einem oder mehreren übereinanderliegenden Metallblechen mit gegebenenfalls rund um die Abgasöffnung laufenden Sicken. Die Dichtung besitzt bei Reihenmotoren entsprechend den Zylindern mehrere nebeneinanderliegende Durchgangs- oder Abgasöffnungen.The flat seals used in practice for exhaust pipes usually exist from one or more metal sheets lying on top of one another, optionally round beads running around the exhaust opening. The seal has in-line engines corresponding to the cylinders, several through or adjacent Exhaust ports.

Die EP 0 473 306 A1 offenbart eine gattungsgemäße Flachdichtung. Die moderne Produktionstechnik zur Herstellung von Verbrennungskraftmaschinen erfordert eine Reduzierung der Einzelteile beim Zusammenbau der Verbrennungskraftmaschine. So werden immer mehr Einzelteile vor dem Einbau zu Komponenten zusammengestellt und am Ende der Produktionskette als Systemkomponenten angeliefert, um dann als Einbaueinheit eingebaut zu werden.EP 0 473 306 A1 discloses a generic flat gasket. The modern Production technology for the production of internal combustion engines requires one Reduction of the individual parts when assembling the internal combustion engine. So more and more individual parts are assembled into components before installation and Delivered as system components at the end of the production chain and then as Installation unit to be installed.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Flachdichtung dahingehend zu verbessern, daß die Dichtung auf einem Flanschkörper vormontierbar ist.The invention has for its object a generic flat gasket to improve in that the seal can be preassembled on a flange body.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an einer Metallblechplatte Zentrier- und Befestigungsmittel angeordnet sind, so daß die Flachdichtung unverlierbar mit einem Flanschkörper verbindbar ist. Auf diese Weise kann die Flachdichtung auf den Flansch, beispielsweise eines Auspuffkrümmers, lagegerecht aufgelegt werden. Die Zentriermittel sorgen dafür, daß die Dichtung die Lage einnimmt, die sie im eingebauten Zustand zur funktionsgerechten Abdichtung benötigt.This object is achieved in that on a sheet metal plate Centering and fastening means are arranged so that the flat seal cannot be lost can be connected to a flange body. In this way, the flat gasket on the Flange, for example an exhaust manifold, are placed in the correct position. The Centering means ensure that the seal assumes the position that it is installed in Condition required for functional sealing.

Vorzugsweise sind die Zentrier- und Befestigungsmittel einstückig mit der Metallblechplatte verbunden. Die Zentrier- und Befestigungsmittel sind als Federbügel ausgebildet und erstrecken sich vorzugsweise am Außenumfang der Flachdichtung. Alternativ besteht die Möglichkeit die Federbügel im Bereich von Schraubendurchgangsöffnungen anzuordnen.The centering and fastening means are preferably in one piece with the Sheet metal plate connected. The centering and fastening means are as spring clips  formed and preferably extend on the outer circumference of the flat gasket. Alternatively, there is the possibility of spring clips in the range of Arrange screw through holes.

Die Erfindung ist anhand eines Ausführungsbeispieles in der Zeichnung dargestellt und wird im folgenden näher erläutert. Es zeigen:The invention is shown using an exemplary embodiment in the drawing and is explained in more detail below. Show it:

Fig. 1 Ansicht einer Verbrennungskraftmaschine Fig. 1 view of an internal combustion engine

Fig. 2 Erfindungsgemäße Flachdichtung gemäß Ansicht II-II aus Fig. 1 Fig. 2 according to the invention flat gasket according to view II-II from Fig. 1

Fig. 3 Schnitt gemäß III-III der Fig. 2 Fig. 3 section according to III-III of Fig. 2

Fig. 4 Schnitt gemäß IV-IV der Fig. 2. Fig. 4 is a section according to IV-IV of FIG. 2.

In der Fig. 1 ist schematisch eine Verbrennungskraftmaschine (1) dargestellt. Zur Herstellung einer solchen Maschine müssen in der Produktionskette eine Vielzahl von einzelnen Bauteilen bereitgestellt und zusammengefügt werden. Zur Abdichtung des Abgasrohres (2) gegenüber dem Motorblock (3) ist eine Flachdichtung (4) (Fig. 2) vorgesehen. Die Flachdichtung (4) ist erfindungsgemäß mit Zentrier- und Befestigungsmitteln (5, 5′) versehen, die beispielsweise als Federbügel ausgebildet sind. Mit Hilfe der Federbügel (5, 5′) ist es nunmehr möglich, die Flachdichtung (4) zum Beispiel beim Hersteller des Abgasrohres auf den Flansch des Abgasrohres (2) zu befestigen. Das Abgasrohr (2) kann dann zusammen mit der Flachdichtung (4) zum Hersteller der Verbrennungskraftmaschine geliefert werden.An internal combustion engine ( 1 ) is shown schematically in FIG. 1. To manufacture such a machine, a large number of individual components must be made available and assembled in the production chain. A flat gasket ( 4 ) ( FIG. 2) is provided to seal the exhaust pipe ( 2 ) from the engine block ( 3 ). The flat seal ( 4 ) is provided according to the invention with centering and fastening means ( 5 , 5 '), which are designed, for example, as a spring clip. With the help of the spring clip ( 5 , 5 '), it is now possible to attach the flat gasket ( 4 ), for example at the manufacturer of the exhaust pipe, to the flange of the exhaust pipe ( 2 ). The exhaust pipe ( 2 ) can then be supplied together with the flat gasket ( 4 ) to the manufacturer of the internal combustion engine.

Die Federbügel (5, 5′) erstrecken sich am Außenumfang einer Metallblechplatte (6) und können einstückig aus der Metallblechplatte (6) herausgeformt sein. The spring clip ( 5 , 5 ') extend on the outer circumference of a sheet metal plate ( 6 ) and can be formed in one piece from the sheet metal plate ( 6 ).

Wie aus der Fig. 3 ersichtlich, greift der Federbügel (5) in eine Ausnehmung (7) des Flansches (8) des Abgasrohres (2). Durch mehrere gleichmäßig am Umfang verteilt angeordnete Federbügel (5) ist die Flachdichtung (4) sowohl auf dem Flansch (8) befestigt als auch zentriert, das heißt die Durchgangsöffnung (9) ist zur Öffnung (9′) des Abgasrohres zentriert.As seen from Fig. 3, the spring clip (5) engages in a recess (7) of the flange (8) of the exhaust pipe (2). By a plurality of uniformly distributed on the periphery arranged spring clips (5), the gasket (4) fitted both to the flange (8) and centered, that is, the through hole (9) is centered relative to the opening (9 ') of the exhaust pipe.

Darüber hinaus besteht die Möglichkeit die Schraubendurchgangsöffnung (10) als korrespondierenden Partner für die Federbügel (5′) auszubilden.In addition, there is the possibility of forming the screw passage opening ( 10 ) as a corresponding partner for the spring clip ( 5 ').

Die Fig. 4 zeigt eine solche Variante bei der ein Federbügel (5′) in die Schraubendurchgangsbohrung des Flansches (8) eingreift. Denkbar wäre auch eine Kombination von am Außenumfang und in den Schraubendurchgangsbohrungen (10) angeordneten Federbügeln (5, 5′). In diesem Fall würde es auch ausreichen, wenn wie in der Fig. 4 dargestellt, in der Schraubendurchgangsöffnung lediglich ein radial angewinkelter Endbereich (11) eingreift, der die Zentrierfunktion übernimmt, während die am Außenumfang angeordneten Federbügel (5) die Befestigungsfunktion übernehmen. Fig. 4 shows such a variant in which a spring clip ( 5 ') engages in the screw through bore of the flange ( 8 ). A combination of spring clips ( 5 , 5 ') arranged on the outer circumference and in the screw through bores ( 10 ) would also be conceivable. In this case, it would also be sufficient if, as shown in FIG. 4, only a radially angled end region ( 11 ) engages in the screw passage opening, which takes over the centering function, while the spring clips ( 5 ) arranged on the outer circumference take over the fastening function.
