Abstract

A cylinder-head gasket (1) for an internal combustion engine has a central hole (1) for the cylinder, holes (3) for the cylinder-head bolts, and holes (4) for the passageways for the circulation of the cooling water and the lubricating oil. The gasket is made of metal and has two embossed ridges (5) around the holes (2) for the cylinder. These ridges project from opposite sides of the gasket. Each of the holes (4) for oil and water circulation has an elastic sealing ring bonded to its inner edge. The sealing ring surfaces project beyond the gasket surface on both sides of the gasket. USE/ADVANTAGE - Cylinder-head gasket with increased thickness to ensure effective sealing in critical areas.

Description

Die Erfindung betrifft eine Zylinderkopfdichtung für Brenn­ kraftmaschinen nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a cylinder head gasket for combustion Engines according to the preamble of patent claim 1.

Derartige Dichtungen sind aus DE-A- 37 11 664 und DE-A- 19 23 482 bekannt.Such seals are from DE-A-37 11 664 and DE-A-19 23 482 known.

Die dort eine Zylinderöffnung jeweils umschließende Verdickung der Metallplatten-Dichtung hat den Zweck, die Vorspannkraft der Schrauben zur Erzielung einer guten Dichtung auf die ver­ dickten Bereiche zu lenken.The thickening enclosing a cylinder opening there The metal plate seal has the purpose of preloading the screws to achieve a good seal on the ver to guide thick areas.

Bei jenen bekannten Ausführungen sind die verdickten Bereiche jedoch nicht so ausgebildet, daß die auf die Dichtplatte ein­ wirkenden Anpreßkräfte tatsächlich auf einen radial engen Be­ reich um die Zylinderöffnung begrenzt sind.In those known designs, the thickened areas however not designed so that the on the sealing plate acting contact forces actually on a radially narrow loading are richly limited around the cylinder opening.

Bei der Dichtung nach DE-A- 19 23 482 ergibt sich dies daraus, daß die Verdickungen einzelne dünne eingeprägte Ringe sind, die unter der Kraft der Spannschrauben soweit nachgeben, daß die Dichtplatte über ihre gesamte Fläche verspannt ist.With the seal according to DE-A-19 23 482 this results from that the thickenings are individual thin embossed rings, the yield under the force of the clamping screws that the sealing plate is clamped over its entire surface.

Bei der Ausführung nach DE-A- 37 11 664 tritt bei einem Nach­ geben der als Sicke geformten Verdickung ebenfalls die Wirkung ein, daß die Dichtplatte auch außerhalb des Verdickungsberei­ ches Einspannkräfte aufnimmt. Auch wenn die eingeprägte Sicke in ihrem aus der Metallplatte erhabenen Bereich nicht voll­ ständig in die Metallplattenoberfläche unter der Einspannkraft zurückgeformt wird, liegt die Metallplatte in jedem Fall immer auf der der erhabenen Seite der Sicke gegenüberliegenden Ober­ fläche der Metallplatte über einen zur Zylinderöffnung radial nach außen über die Verdickung herausragenden Bereich an der Gegenfläche unter Spannkraft an.In the execution according to DE-A-37 11 664 occurs at a night also give the thickening shaped as a bead the effect a that the sealing plate also outside the thickening area ches absorbs clamping forces. Even if the embossed bead not full in its area raised from the metal plate  constantly in the metal plate surface under the clamping force is reshaped, the metal plate always lies on the upper side opposite the raised side of the bead area of the metal plate over a radial to the cylinder opening outwardly beyond the thickening area at the Counter surface under tension.

Hier eine Verbesserung zu schaffen, ist die Aufgabe der vor­ liegenden Erfindung.To create an improvement here is the task of before lying invention.

Gelöst wird diese Aufgabe durch die Ausführung der gattungsge­ mäßen Zylinderkopfdichtung nach den kennzeichnenden Merkmalen des Patentanspruchs 1.This task is solved by the execution of the genus moderate cylinder head gasket according to the characteristic features of claim 1.

Zweckmäßige Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Appropriate embodiments of the invention are the subject of Subclaims.

Die Ausbildung der Verdickung als Sicke hat den Vorteil, daß diese sich in dem zu dichtenden Bereich durch Verformung den Dichtflächen anpassen kann.The formation of the thickening as a bead has the advantage that these are deformed in the area to be sealed Can adjust sealing surfaces.

Der dickenmäßig gestufte Übergang aus dem Sickenbereich in den sich daran anschließenden übrigen Bereich der Metallplatte stellt sicher, daß auch bei einem dickenmäßigen Nachgeben des maximal verdickten Bereiches die Metallplatte noch immer nicht über ihren gesamten Bereich zur Anlage an die Dichtflächen ge­ langen kann, sondern lediglich in dem Zwischenstufenbereich.The thickness-graded transition from the bead area to the adjoining remaining area of the metal plate ensures that even when the thickness of the maximum thickened area, the metal plate still not ge over their entire area to abut the sealing surfaces long, but only in the intermediate stage area.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.An embodiment of the invention is in the drawing shown.

Fig. 2 einen Schnitt durch die Dichtung nach Linie II-II, Fig. 2 shows a section through the gasket along line II-II,

Fig. 3 einen Schnitt durch die Dichtung nach Linie III-III. Fig. 3 shows a section through the seal along line III-III.

Die aus einer Metallplatte 1 bestehende Zylinderkopfdichtung umschließt in dem gezeigten Ausführungsbeispiel lediglich eine zentrale Zylinderöffnung 2 und besitzt Durchgangsöffnungen 3 für Spannschrauben und Durchgangsöffnungen 4 für Kühl- und Schmiermittel.In the exemplary embodiment shown, the cylinder head gasket consisting of a metal plate 1 only surrounds a central cylinder opening 2 and has through openings 3 for tensioning screws and through openings 4 for coolant and lubricant.

In dem Bereich um die Zylinderöffnung 2 ist die Metallplatte 1 ringförmig durch Einprägen einer Sicke 5 verdickt. Von der sickenförmigen Verdickung nimmt die Plattendicke über eine Zwischenstufe 6 auf einen beidseitig zurückgenommenen Bereich einer durchgehend geringsten Dicke ab. Die Metallplatten­ verdünnung von der Zwischenstufe 6 gegenüber dem dünnsten Bereich beträgt auf jeder Seite der Metallplatte etwa s=0,1 mm.In the area around the cylinder opening 2 , the metal plate 1 is thickened in a ring shape by embossing a bead 5 . The plate thickness decreases from the bead-shaped thickening via an intermediate stage 6 to an area of a continuously reduced thickness that is recessed on both sides. The metal plate dilution from the intermediate stage 6 compared to the thinnest area is approximately s = 0.1 mm on each side of the metal plate.

Die einstückige Ausführung der Metallplatte 1 gewährleistet eine größtmögliche Dauerfestigkeit gegenüber Kräften, die in der Ebene der Dichtfläche wirken.The one-piece design of the metal plate 1 ensures the greatest possible fatigue strength against forces that act in the plane of the sealing surface.

Zur Dichtung der Schmier- und/oder Kühlmittel führenden Durch­ gangsöffnungen sind in deren Randbereichen elastische Dich­ tungen 7 an der Metallplatte 1 angebracht.To seal the lubricant and / or coolant leading through openings elastic lines 7 are attached to the metal plate 1 in their edge regions.
