Nachteilig bei den aus den oben genannten Druckschriften bekannten Zylinderkopfdichtungen ist insbesondere, dass zur Erzielung einer zuverlässigen Abdichtung hohe Montage- und Flächenpressungskräfte benötigt werden. Dies belastet die Bauteile und lässt die Gefahr von Fehlfunktionen aufgrund von Materialermüdung steigen.adversely in the cylinder head gaskets known from the above-mentioned publications In particular, that is to achieve a reliable seal high assembly and surface pressure forces are required. This loads the components and leaves the risk of malfunction due to material fatigue increases.
Aufgabe der Erfindung ist es demgegenüber, eine Dichtung bereitzustellen, welche selbstverstärkend zwischen dem Zylinderkopf und dem Zylinderblock bzw. den Laufbuchsen der Brennkraftmaschine ohne die Notwendigkeit hoher Flächenpressungskräfte angeordnet ist.task the invention it is in contrast, a To provide seal which self-reinforcing between the cylinder head and the cylinder block or liners of the internal combustion engine without the need for high surface pressure forces arranged is.
Diese Aufgabe wird durch eine Dichtung mit den Merkmalen des Anspruchs 1 gelöst.These The object is achieved by a gasket having the features of the claim 1 solved.
Die erfindungsgemäße Dichtung zeichnet sich durch eine Form und Anordnung aus, welche erlaubt, den Brennraumdruck als unterstützende Kraft zur Abdichtung des Zylinderkopfes gegen den Zylinderblock einer Brennkraftmaschine zu integrieren. Die Dichtung wird dabei durch den Brennraumdruck elastisch verformt und gegen die angrenzenden Strukturen und Bauteile gepresst. Ein planer Zylinderkopf kann ohne die aufwendige Einbringung von Nuten verwendet werden, ohne dass die Dichtwirkung beeinträchtigt wird.The inventive seal characterized by a shape and arrangement which allows the combustion chamber pressure as supporting Force to seal the cylinder head against the cylinder block to integrate an internal combustion engine. The seal will be there deformed elastically by the combustion chamber pressure and against the adjacent structures and components pressed. A flat cylinder head can do without the elaborate Insertion of grooves can be used without affecting the sealing effect impaired becomes.
In einer Ausgestaltung der Erfindung ist die Dichtung aus einem Grundkörper und einem Träger ausgebildet, welche in einem Zwischenraum zwischen dem Zylinderkopf und dem Zylinderblock angeordnet sind.In one embodiment of the invention, the seal of a base body and a carrier is formed, which in an intermediate space between the cylinder head and the cylinder block are ordered.
In weiterer Ausgestaltung der Erfindung ist die Dichtung in einer Ausnehmung des Zylinderblocks angeordnet.In Another embodiment of the invention, the seal in a recess arranged the cylinder block.
In weiterer Ausgestaltung der Erfindung ist die Ausnehmung wahlweise vom Zylinderblock und einer Laufbuchse, einem Ölabstreifring und dem Zylinderkopf begrenzt.In Further embodiment of the invention, the recess is optional from the cylinder block and a liner, an oil scraper ring and the cylinder head limited.
In weiterer Ausgestaltung der Erfindung ist ein Distanzstück vorgesehen, welches den Zylinderblock und den Zylinderkopf beabstandet, an welchem die Dichtung anliegt.In Further embodiment of the invention, a spacer is provided, which spaced the cylinder block and the cylinder head, on which the Gasket is applied.
In weiterer Ausgestaltung der Erfindung kann auch eine herkömmliche Zylinderkopfdichtung vorgesehen sein, welche mit der erfindungsgemäß ausgestalteten Dichtung und einem Distanzstück kombinierbar ist.In Another embodiment of the invention may also be a conventional Cylinder head gasket may be provided, which with the inventively designed Seal and a spacer combined is.
Weitere Merkmale und Merkmalskombinationen ergeben sich aus der Beschreibung sowie den Zeichnungen. Konkrete Ausführungsbeispiele der Erfindung sind in den Zeichnungen vereinfacht dargestellt und in der nachfolgenden Beschreibung näher erläutert. Es zeigenFurther Features and combinations of features result from the description as well as the drawings. Specific embodiments of the invention are shown in simplified form in the drawings and in the following Description explained in more detail. It demonstrate
Die Anforderungen an die Dichtwirkung von Dichtungen für Brennkraftmaschinen werden mit zunehmender Leistung der modernen Brennkraftmaschinen immer höher, sodass sowohl an das Material der Dichtungen als auch an die übrigen Bauteile immer höhere Anforderungen gestellt werden. Dies gilt sowohl für gemischverdichtende, fremdgezündete als auch in verstärktem Maße für selbstzündende Brennkraftmaschinen.The Requirements for the sealing effect of seals for internal combustion engines be with increasing performance of modern internal combustion engines higher and higher, so that both the material of the seals and the other components ever higher Requirements are made. This applies both to mixture compacting, strangely ignited as also in reinforced Dimensions for self-igniting internal combustion engines.
Um die Dichtwirkung der Dichtung zu verbessern, ist es zunächst sinnvoll, das Profil der Dichtung aus einem flächigen in ein räumliches Profil zu überführen. Solche vorzugsweise runden Profile sind bereits aus dem Stand der Technik bekannt. Der hauptsächliche Nachteil der bekannten flächigen und räumlich profilierten Dichtungen liegt dabei in den hohen Montage- und Flächenpressungskräften, die aufgewendet werden müssen, um eine zuverlässige Dichtwirkung zu erzielen. Dabei muss einerseits die Herstellung der die Dichtung begrenzenden Flächen sehr präzise erfolgen, damit die gewünschte Dichtwirkung erzielt werden kann, was zu einem teuren und aufwendigen Herstellungsprozess führt, andererseits treten hohe Kräfte sowohl bei der Montage als auch beim Betrieb der Brennkraftmaschine auf, die auf die einzelnen Bauteile wirken. In der Folge treten Materialermüdung und damit eine Verschlechterung der Dauerlaufeigenschaften und der Lebensdauer der Brennkraftmaschine auf.Around to improve the sealing effect of the seal, it makes sense at first, the profile of the seal from a flat to a spatial To convict profile. Such preferably round profiles are already known in the art known. The main one Disadvantage of the known planar and spatially profiled seals lies in the high assembly and surface pressure forces that have to be spent a reliable sealing effect to achieve. It must on the one hand the production of the seal very limited areas precise done so that the desired Sealing effect can be achieved, resulting in an expensive and expensive Manufacturing process leads, On the other hand, high forces occur both during assembly and during operation of the internal combustion engine on, which act on the individual components. In the episode occur fatigue and thus a deterioration of the endurance characteristics and the Life of the internal combustion engine on.
Im Gegensatz dazu ist eine erfindungsgemäß ausgestaltete Dichtung dadurch ausgezeichnet, dass sich ihre Wirkung auch ohne hohe Montage- und Flächenpressungskräfte durch eine Selbstverstärkung durch den Brennraumdruck entfaltet. In den folgenden Figuren ist die Richtung des Brennraumdrucks jeweils durch Pfeile gekennzeichnet.in the In contrast, a seal designed according to the invention is characterized excellent, that their effect even without high assembly and Surface pressure forces through a self-reinforcement deployed through the combustion chamber pressure. In the following figures is the direction of the combustion chamber pressure is indicated by arrows.
