Description
Metallische Flachdichtung . .Metallic flat gasket . .
Beschreibung:Description:
Die Neuerung betrifft eine metallische Flachdichtung, insbesondere Zylinderkopfdichtung, mit einem Dichtungsblech und einer Brennraumöfihung sowie einer die Brennraumöfihung umschließenden Sicke, wobei in der Brennraumöfihung ein an der Stirnseite des Dichtungsbleches anliegender Ring mit größerer Dicke als das Dichtungsblech eingesetzt ist.The innovation concerns a metallic flat gasket, in particular a cylinder head gasket, with a sealing plate and a combustion chamber opening as well as a bead enclosing the combustion chamber opening, whereby a ring with a greater thickness than the sealing plate is inserted into the combustion chamber opening and rests against the front side of the sealing plate.
Um Schadraumvolumen im Bereich der Zylinderkopfdichtung zu verringern, wird bei metallischen Zylinderkopfdichtungen verstärkt der Einsatz von kleinen Einbauhöhen gefordert. Dieser Forderung wird man mit einlagigen Stahldichtungen am besten gerecht. Die einlagigen Stahldichtungen weisen jedoch das Problem auf, daß die zur Abdichtung des Brennraumes notwendige Sicke gegen Verformung geschützt werden muß. Die US-PS 3 053 544 zeigt eine einlagige Flachdichtung, bei der die Sicke durch Umbördeln des Dichtungsrandes geschützt wird. Das Umbördeln einer Stahldichtung birgt aber das Risiko, daß das Material leicht brechen kann.In order to reduce the volume of the dead space in the area of the cylinder head gasket, the use of small installation heights is increasingly required for metal cylinder head gaskets. This requirement is best met with single-layer steel gaskets. However, single-layer steel gaskets have the problem that the bead required to seal the combustion chamber must be protected against deformation. US-PS 3 053 544 shows a single-layer flat gasket in which the bead is protected by flanging the sealing edge. Flanging a steel gasket, however, carries the risk that the material can easily break.
Der Neuerung liegt die Aufgabe zugrunde, eine gattungsgemäße metallische Flachdichtung im Hinblick auf die Abdichtung im Brennraumbereich zu verbessern, wobei gleichzeitig die Herstellungskosten gesenkt werden.The innovation is based on the task of improving a generic metallic flat gasket with regard to sealing in the combustion chamber area, while at the same time reducing the manufacturing costs.
Diese Aufgabe wird neuerungsgemäß durch die Merkmale der Ansprüche 1 und 2 gelöst. Vorteilhafte Ausgestaltungen ergeben sich a.us den Unteransprüchen.This object is solved according to the invention by the features of claims 1 and 2. Advantageous embodiments emerge from the subclaims.
Die Neuerung ist anhand eines Ausfuhrungsbeispieles in der Zeichnung dargestellt und wird im folgenden erläutert:The innovation is shown using an example in the drawing and is explained below:
Figur 1 eine Teilansicht einer Zylinderkopfdichtung für Reihenmotoren Figur 2 einen Teilschnitt gemäß Angabe in Figur 1Figure 1 is a partial view of a cylinder head gasket for in-line engines Figure 2 is a partial section as shown in Figure 1
Figur 3 eine alternative Ausbildung gemäß Figur 2Figure 3 an alternative design according to Figure 2
Die Zylinderkopfdichtung nach Figur 1 besteht im wesentlichen aus dem metallischen Dichtungsblech (1) in dem Durchbrüche für Kühl- und Schmiermittelkanäle (2, 3), Schraubenbolzen (4) sowie Brennraumöfrhungen (5) eingestanzt sind.The cylinder head gasket according to Figure 1 consists essentially of the metallic sealing sheet (1) in which openings for coolant and lubricant channels (2, 3), screw bolts (4) and combustion chamber openings (5) are punched.
Wie aus der Figur 2 ersichtlich, werden die Brennraumöflhungen (5) von einer umlaufenden, eingeprägten Sicke (6) umschlossen. Die Abdichtung des Brennraumes erfolgt über einen Ring (7), welcher in die Brennraumöfmung eingesetzt ist. Der Ring (7) ist durch Schweißnähte, die im Laserschweißverfahren erzeugt wurden, mit dem Dichtungsblech (1) verbunden.As can be seen from Figure 2, the combustion chamber openings (5) are surrounded by a circumferential, embossed bead (6). The combustion chamber is sealed by a ring (7) which is inserted into the combustion chamber opening. The ring (7) is connected to the sealing plate (1) by weld seams which were created using a laser welding process.
Die Figur 3 zeigt eine alternative Befestigung des Ringes (7), indem der Ring durch Schrumpfen (9) verbunden ist. Denkbar wäre es auch, den Ring (7) durch Verstemmen mit dem Dichtungsblech (1) zu verbinden.Figure 3 shows an alternative fastening of the ring (7), in which the ring is connected by shrinking (9). It would also be conceivable to connect the ring (7) to the sealing plate (1) by caulking.
