Flachdichtung, insbesondere ZylinderkopfdichtungFlat gasket, especially cylinder head gasket
Die Neuerung betrifft eine Flachdichtung, insbesondere Zylinderkopfdichtung fur Verbrennungskraftmaschinen.The innovation concerns a flat gasket, in particular cylinder head gaskets for internal combustion engines.
Der US-A 5,601,291 ist eine metallische Flachdichtung zu entnehmen, die mehrere mit Sicken versehene Funktionslagen beinhaltet, die mit mehreren nebeneinander liegenden Durchgangsöffhungen, sowie Schrauben-durchgangslöchern und Kanälen für den Flüssigkeitsdurchtritt versehen ist. Im Bereich der Durchgangsöffhungen sind sogenannte Stopperelemente vorgesehen, die an unterschiedlichen Stellen der Funktionslagen plaziert sein können. Die Funktionslagen sollen aus einem nicht rostenden Stahl (SUS 301) mit einer Dicke zwischen 0,2 und 0,25 mm bestehen, während das Stopperelement aus einem nicht rostenden Stahl (SUS 304) bestehen soll, das eine Dicke von 0,01 bis 0,1 mm aufweist. Bei Dichtungen im allgemeinen und Zylinderkopfdichtungen im speziellen, beinhaltend Stopperelemente, kommt es je nach Wahl der Materialien, die miteinander verbunden werden zu Problemen im motorischen Betrieb dergestalt, dass in folge Relativbewegungen, resultierend aus unterschiedlichen Ausdehnungskoeffizienten der miteinander kombinierten Materialien, die Stopperelemente einer hohen Scherbeanspruchung unterliegen, so dass es hier zu Zerstörungen im Bereich der Stopperzone kommen kann.US-A 5,601,291 describes a metallic flat gasket that contains several functional layers with beads, which are provided with several adjacent through holes, as well as screw through holes and channels for the passage of liquid. In the area of the through holes, so-called stopper elements are provided, which can be placed at different points on the functional layers. The functional layers should be made of a stainless steel (SUS 301) with a thickness between 0.2 and 0.25 mm, while the stopper element should be made of a stainless steel (SUS 304) with a thickness of 0.01 to 0.1 mm. In the case of seals in general and cylinder head gaskets in particular, including stopper elements, depending on the choice of materials that are connected to one another, problems arise during engine operation in such a way that, as a result of relative movements resulting from different expansion coefficients of the combined materials, the stopper elements are subject to high shear stress, so that destruction can occur in the stopper zone.
Der Neuerung liegt die Aufgabe zugrunde, eine Flachdichtung, insbesondere eine Zylinderkopfdichtung für Verbrennungskraftmaschinen, dahingehend weiterzubilden, dass Beschädigungen bzw. Zerstörungen im Bereich der Stopperzonen minimiert werden, so dass die Standzeit der Flachdichtung, insbesondere der Zylinderkopfdichtung, erhöht wird.The innovation is based on the task of further developing a flat gasket, in particular a cylinder head gasket for internal combustion engines, in such a way that damage or destruction in the area of the stopper zones is minimized, so that the service life of the flat gasket, in particular the cylinder head gasket, is increased.
Diese Aufgabe wird neuerungsgemäß gelöst durch eine Flachdichtung, insbesondere Zylinderkopfdichtung für Verbrennungskraftmaschinen, mit mindestens einer,This task is solved by a flat gasket, in particular a cylinder head gasket for internal combustion engines, with at least one,
• · ♦ <• · ♦ <
mindestens eine Durchgangsöffnung beinhaltenden metallischen Funktionslage und mindestens einem im Bereich der Durchgangsöffhung vorgesehenen, etwa ringförmig ausgebildeten metallischen Stopperelement, das schweißtechnisch mit der Funktionslage verbunden ist, wobei die Funktionslage und das Stopperelement aus metallischen Werkstoffen mit im wesentlichen gleichen thermischen Ausdehnungskoeffizienten bestehen.at least one metallic functional layer containing a through-opening and at least one approximately ring-shaped metallic stopper element provided in the region of the through-opening, which is connected to the functional layer by welding, wherein the functional layer and the stopper element consist of metallic materials with essentially the same thermal expansion coefficients.
Vorteilhafte Weiterbildungen des Neuerungsgegenstandes sind den Unteransprüchen zu entnehmen.Advantageous further developments of the subject matter of the innovation can be found in the subclaims.
Zur Erziehlung im wesentlichen identischer bzw. identischer Ausdehnungskoeffizienten können nun diverse Werkstoffe miteinander kombiniert werden. Dies können Chrom-Nickel-Legierungen oder aber Eisen-Nickel-Legierungen mit geringen thermischen Ausdehnungskoeffizienten sein. Bevorzugt werden jedoch Werkstoffe aus exakt demselben identischen Material ausgewählt, die nicht nur die gleiche Stoffklasse beinhalten, sondern, einem weiteren Gedanken der Neuerung gemäß, identische Materialien derselben Werkstoffnummer sind, um auf diese Weise auch tatsächlich identische Ausdehnungskoeffizienten zu erhalten. Dies erleichtert die Materialauswahl. Das Stopperelement wird schweißtechnisch mit der Funktionslage verbunden, so dass bei identischem Ausdehnungskoeffizienten die Scherbeanspruchung des Stopperelementes nicht mehr gegeben ist.To achieve essentially identical or identical expansion coefficients, various materials can be combined with one another. These can be chromium-nickel alloys or iron-nickel alloys with low thermal expansion coefficients. However, materials made from exactly the same identical material are preferred, which not only contain the same material class, but, in accordance with another idea of the innovation, are identical materials with the same material number, in order to actually obtain identical expansion coefficients. This makes material selection easier. The stopper element is welded to the functional layer so that the shear stress on the stopper element is no longer present when the expansion coefficients are identical.
Die Materialauswahl wird der Fachmann an die Betriebsverhältnisse, insbesondere der Verbrennungskraftmaschine, anpassen.The specialist will adapt the choice of material to the operating conditions, especially of the internal combustion engine.
Der Neuerungsgegenstand ist anhand von Prinzipskizzen verdeutlicht.The innovation is illustrated by means of schematic diagrams.
In der Prinzipskizze 1 ist eine Zylinderkopfdichtung 1 für eine Verbrennungskraftmaschine dargestellt, die in diesem Beispiel aus einer einzelnen metallischen Funktionslage 2 aus einer Chrom-Nickel-Legierung bestehen soll. Angedeutet ist eine Durchgangsöffnung 3, die einen Brennraumbereich darstellt. UmThe schematic diagram 1 shows a cylinder head gasket 1 for an internal combustion engine, which in this example is intended to consist of a single metallic functional layer 2 made of a chromium-nickel alloy. A through opening 3 is indicated, which represents a combustion chamber area.
die Durchgangsöffnung 3 herum erstreckt sich eine Sicke 4. Vor der Sicke 4, das heißt, der Durchgangsöffnung 3 zugewandt, ist ein ringförmig ausgebildetes Stopperelement 5 vorgesehen, das zum Beispiel durch Punktschweißen 6 mit der Funktionslage 2 verbunden ist. Das Stopperelement 5 besteht in diesem Beispiel ebenfalls aus einer Chrom-Nickel-Legierung, wobei zur Erziehlung identischer Ausdehnungskoeffizienten, identische Materialien derselben Werkstoffhummer ausgewählt wurden.A bead 4 extends around the through-opening 3. In front of the bead 4, i.e. facing the through-opening 3, a ring-shaped stopper element 5 is provided, which is connected to the functional layer 2, for example by spot welding 6. The stopper element 5 in this example also consists of a chromium-nickel alloy, whereby identical materials of the same material lobes were selected to achieve identical expansion coefficients.
Bei Bedarf können mehrere Funktionslagen 2', 2" und bedarfsweise auch Distanzlagen 7 eingesetzt werden, um die Zylinderkopfdichtung dem jeweiligen Betriebszustand anzupassen (Fig 2).If required, several functional layers 2', 2" and, if necessary, spacer layers 7 can be used to adapt the cylinder head gasket to the respective operating condition (Fig. 2).
