Abstract

The cylinder-head gasket in used in an internal combustion engine and gives a watertight and gas-tight seal around the cylinders. The portion (7) of the gasket adjacent to each cylinder is thicker than the portion (4) more remote from the cylinders. There is a groove (5,6) on the top and bottom surface of the gasket, between the thick and thin portions. The grooves completely surround the cylinders, and may join to form a single groove in the narrow region between two cylinders. The gasket has a thin skin (2,3) of constant thickness on its top and bottom surface and has a core of greater thickness. The groove surrounding the cylinder heads is formed by a rectangular-section cutout (13) in the core into which the covering layer may bilge (12).

Description

Die Erfindung betrifft eine metallische Flachdichtung, insbesondere Zylinderkopfdichtung, bestehend aus zwei Deckblechen mit mindestens je einer eine Brennraumöffnung umgebenden Sicke und einer zwischen den Deckblechen angeordneten Distanzlage, deren freier Endbereich zur Erzielung einer definierten Flächenpressung axial dicker als der übrige Bereich ausgebildet ist, und die Sicken symmetrisch zueinander mit ihrer konvexen Aufwölbung in Richtung der Distanzlage sich erstrecken.The invention relates to a metallic flat gasket, in particular Cylinder head gasket, consisting of two cover plates with at least one each Bead surrounding the combustion chamber opening and one between the cover plates arranged distance, the free end area to achieve a defined Surface pressure is formed axially thicker than the rest of the area, and the beads symmetrical to each other with their convex bulge in the direction of the distance extend.

Die EP 0 306 766 offenbart eine gattungsgemäße Zylinderkopfdichtung. Zwischen zwei Deckblechen erstreckt sich eine Distanzlage, die an den Brennraumöffnungen umgefalzt oder gebördelt ist. Über diese Dickenerhöhung wird eine hohe Pressung am Brennraum ermöglicht, ohne daß die Sicken plattgedrückt werden können.EP 0 306 766 discloses a generic cylinder head gasket. Between two Cover plates extend a distance layer, which is folded over at the combustion chamber openings or is crimped. This increase in thickness results in a high pressure on the combustion chamber made possible without the beads being pressed flat.

Je nach Aufbau der Zylinderkopfdichtung kann die geforderte Einbaudicke, welche über die Distanzplatte einstellbar ist, relativ groß sein. In diesem Fall ergibt sich das Problem, daß der umgefalzte Endbereich der Distanzplatte eine sehr große axiale Höhe der Zylinderkopfdichtung mit sich bringt. Je nach Anwendungsfall sind unterschiedlich dicke Distanzlagen notwendig. Die Folge dieser Dickenvariation ist, daß der optimale Funktionsbereich der Sicke bei gleichen Deckblechen nicht immer eingestellt werden kann.Depending on the structure of the cylinder head gasket, the required installation thickness, which is about the spacer plate is adjustable, be relatively large. In this case, the problem arises that the folded end portion of the spacer plate has a very large axial height Cylinder head gasket. Depending on the application, there are different thicknesses Distance positions necessary. The consequence of this thickness variation is that the optimum Functional area of the bead cannot always be set with the same cover plates can.

Der Erfindung liegt die Aufgabe zugrunde, den Einsatz vorhandener Deckbleche auf unterschiedlich axial dicke Distanzlagen zu optimieren. Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen. Durch das Einprägen der Ausnehmungen in die Distanzlage können gleiche Sickengeometrien für unterschiedlich dicke Distanzlagen, beziehungsweise für unterschiedliche Dickenerhöhungen am Endbereich der Distanzlage verwendet werden.The invention has for its object the use of existing cover plates to optimize different axially thick spacers. This task will solved according to the invention by the characterizing features of patent claim 1. Advantageous refinements of the invention result from the subclaims. By impressing the recesses in the spacing, the same can Bead geometries for spacers of different thicknesses, or for different increases in thickness are used at the end of the spacer.

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

Fig. 1 erfindungsgemäße Flachdichtung von der Draufsicht Fig. 1 flat gasket according to the invention from the top view

Fig. 2 Ansicht gemäß Schnittlinie II-II der Fig. 1 Fig. 2 view according to section line II-II of Fig. 1

Fig. 3 alternative Ausgestaltung gemäß Fig. 2 Fig. 3 alternative embodiment according to Fig. 2

Fig. 4 weitere Alternative gemäß Fig. 2 Fig. 4 a further alternative, as shown in FIG. 2

Die in der Fig. 1 dargestellte metallische Zylinderkopfdichtung (1) besteht im wesentlichen aus zwei als Deckbleche (2, 3) ausgebildete Federstahlbleche und einer Distanzlage (4, 4′, 4′′) (Fig. 2). Die Deckbleche (2, 3) weisen je eine Sicke (5, 6) auf, die in einer gemeinsamen Vertikalebene liegen. Die Sicken (5, 6) stützen sich auf der Distanzlage (4) ab. Damit die Sicken (5, 6) nicht plattgedrückt werden können, ist eine axiale Verdickung (7) an der Stirnseite (8) der Distanzlage (4) vorgesehen. The metallic cylinder head gasket ( 1 ) shown in Fig. 1 consists essentially of two spring steel plates designed as cover plates ( 2 , 3 ) and a spacer layer ( 4 , 4 ', 4 '') ( Fig. 2). The cover plates ( 2 , 3 ) each have a bead ( 5 , 6 ) which lie in a common vertical plane. The beads ( 5 , 6 ) are supported on the distance layer ( 4 ). So that the beads ( 5 , 6 ) cannot be pressed flat, an axial thickening ( 7 ) is provided on the end face ( 8 ) of the spacer layer ( 4 ).

Die axiale Verdickung (7) kann durch Schmieden der Distanzlage (4) oder durch ringförmige Auflagen (9) (Fig. 3) oder durch eine Metallage (10), die am Endbereich (11) gefalzt ist, gebildet sein (Fig. 4). Die Distanzlage (4, 4′, 4′′) weist im Bereich der konvexen Aufwölbung (12) eine Ausnehmung (13) zur Aufnahme der Sicken (5, 6) auf. Die Tiefe der Ausnehmung (13) ist abhängig von der notwendigen Verdickung (7) und liegt vorzugsweise im Bereich von 20-100 µm. Je nach Anwendungsfall kann die Ausnehmung (13) auch nur auf einer Oberfläche der Distanzlage (Fig. 4) angeordnet sein.The axial thickening ( 7 ) can be formed by forging the spacer layer ( 4 ) or by annular supports ( 9 ) ( Fig. 3) or by a metal layer ( 10 ) which is folded at the end region ( 11 ) ( Fig. 4) . The spacer ( 4 , 4 ', 4 '') has a recess ( 13 ) for receiving the beads ( 5 , 6 ) in the region of the convex bulge ( 12 ). The depth of the recess ( 13 ) depends on the necessary thickening ( 7 ) and is preferably in the range of 20-100 microns. Depending on the application, the recess ( 13 ) can also be arranged only on one surface of the spacer layer ( FIG. 4).
