Abstract
Description
Die Erfindung betrifft eine Zylinderkopfdichtung für eine Brennkraftmaschine gemäß den weiteren im Oberbegriff des Patentanspruches 1 angegebenen Merkmalen.The The invention relates to a cylinder head gasket for an internal combustion engine according to the others in the preamble of claim 1 specified characteristics.
Aus
der
Der Erfindung liegt daher die Aufgabe zugrunde, die gattungsgemäße Zylinderkopfdichtung derart zu verbessern, dass insbesondere auch eine Verbindung von verdeckt angeordneten Metallblechplatten an nicht sichtbaren Bereichen durch Schweißen möglich ist.Of the Invention is therefore based on the object, the generic cylinder head gasket such To improve that in particular also a connection of obscured arranged sheet metal plates in non-visible areas by welding possible is.
Die Aufgabe ist erfindungsgemäß durch die im kennzeichnenden Teil des Patentanspruches 1 angegebenen Merkmale gelöst.The Task is inventively by the features specified in the characterizing part of claim 1 solved.
Die erfindungsgemäße Zylinderkopfdichtung hat den Vorteil, dass auf einfache Weise mittels Punkt- oder Laserschweißung eine Verbindung der Metallblechplatten untereinander auch an nicht von außen sichtbaren bzw. nicht direkt erreichbaren Bereichen möglich ist. Außerdem wird durch diese Art der Schweißverbindung der Metallblechlagen ein Bauraumvorteil erreicht, da auf eine sonst übliche Nietverbindung verzichtet werden kann und somit der übliche Nietkopfüberstand entfällt.The inventive cylinder head gasket has the advantage that in a simple way by means of spot or laser welding a Connection of the sheet metal plates with each other also not visible from the outside or not directly accessible areas is possible. In addition, will through this type of welded joint the sheet metal layers achieved a space advantage, since an otherwise common riveted joint can be omitted and thus the usual Nietkopfüberstand eliminated.
Weitere Merkmale, Vorteile und Einzelheiten der Erfindung ergeben sich aus der folgenden Zeichnungsbeschreibung von zwei bevorzugten Ausführungsformen der erfindungsgemäßen ZylinderkopfdichtungFurther Features, advantages and details of the invention will become apparent the following description of two preferred embodiments the cylinder head gasket according to the invention
