Abstract
Die Erfindung betrifft einen mediumgekühlten Zylinderkopf einer Brennkraftmaschine. DOLLAR A Erfindungsgemäß wird ein gießtechnisch optimierter Zylinderkopf angegeben. Dies wird dadurch erreicht, dass der Zylinderkopf 1 in Richtung von einer Brennraumplatte 2 zu einer oberen Zylinderkopfdeckleiste 5 so ausgebildet ist, dass in dem dazwischen liegenden überwiegenden Erstreckungsbereich die die Form des Zylinderkopfs bestimmenden Gießformen Bestandteile der Unterform und der Oberform sind.The invention relates to a medium-cooled cylinder head of an internal combustion engine. DOLLAR A According to the invention a casting technology optimized cylinder head is specified. This is achieved in that the cylinder head 1 in the direction of a combustion chamber plate 2 to an upper cylinder head cover strip 5 is formed so that in the intermediate predominant extension region, the shape of the cylinder head determining molds are components of the lower mold and the upper mold.
Description
Die Erfindung betrifft einen Zylinderkopf einer Brennkraftmaschine, wobei der Zylinderkopf mediumgekühlt ist und zumindest je Zylinder einen ringförmigen, den Zylinder umfassenden Kühlmittelraum sowie Kühlmittelleitungen aufweist, wobei in den Zylinderkopf weiterhin von Gaswechselventilen beherrschte Gaswechselkanäle eingelassen sind, die eine den Zylinderkopf brennraumseitig zum Zylinder abschließende Brennraumplatte durchdringen.The Invention relates to a cylinder head of an internal combustion engine, wherein the cylinder head is medium-cooled is and at least each cylinder an annular, the cylinder comprehensive Coolant room as well Coolant lines having, wherein in the cylinder head continue from gas exchange valves controlled gas exchange channels are admitted, the one cylinder head combustion chamber side to Cylinder final Penetrate combustion chamber plate.

derartige Brennkraftmaschine ist aus der
Der Erfindung liegt die Aufgabe zugrunde, einen gattungsgemäßen Zylinderkopf anzugeben, der gießtechnisch optimiert ist.Of the Invention is based on the object, a generic cylinder head specify the casting technique is optimized.
Diese Aufgabe wird dadurch gelöst, dass der Zylinderkopf in Richtung von der Brennraumplatte zu einer oberen Zylinderkopfdeckelseite so ausgebildet ist, dass in dem dazwischen liegenden überwiegenden Erstreckungsbereich die die Form des Zylinderkopfes bestimmenden Gießformen Bestandteile der Unterform und der Oberform sind. Dies hat Vorteile hinsichtlich der Gestaltung der Gießform als auch hinsichtlich der späteren Entformung des Zylinderkopfes aus der Gießform. Dadurch, dass die die Form des Zylinderkopfes bestimmenden Gießformen im Wesentlichen Bestandteile der Unterform und der Oberform sind, ist die Gestaltung und auch die Montage dieser Formen wesentlich verbessert und beispielsweise die Gefahr von Fehlgüssen durch Fehler der Gießform, beispielsweise durch schlechte oder unzureichende Verbindung von verschiedenen Gießkernen, verringert. Dadurch ergibt sich umgekehrt der Vorteil, dass das Gussstück weniger komplizierte Formen aufweist, die schwierig zu entformen sind und bei denen die Gefahr von verbleibendem Gießsand in dem fertigen Gussteil groß ist.These Task is solved by that the cylinder head in the direction of the combustion chamber plate to a upper cylinder head cover side is formed so that in between lying predominant Extension area which determines the shape of the cylinder head molds Components of the lower mold and the upper mold are. This has advantages in terms of the design of the mold as well as regarding the later ones Removal of the cylinder head from the mold. By doing that the shape The cylinder head determining molds are essentially components the lower mold and the upper mold are, the design is as well the assembly of these forms significantly improved and, for example the risk of misspunes due to casting mold errors, for example, due to poor or insufficient connection of different casting cores, reduced. This in turn results in the advantage that the casting has less complicated shapes that are difficult to demold are and where the risk of remaining foundry sand in the finished casting is big.
In weiterer Ausgestaltung der Erfindung sind die Gaswechselkanalkerne von einem Gaswechselkanalrechen gehalten und der Gaswechselkanalrechen weist Kernfinger auf, die eine Entkopplung der Auslasskanalwandung von der Brennraumplatte bewirken. Hierdurch ist in konsequenter Weiterführung erreicht, dass ein vorhandener bzw. notwendiger Rechen so weit wie möglich die geforderten und benötigten Kerne zur Ausgestaltung des Zylinderkopfes beinhaltet.In Another embodiment of the invention are the Gaswechselkanalkerne held by a Gaswechselkanalrechen and the Gaswechselkanalrechen has core fingers, which decouple the Auslasskanalwandung effect from the combustion chamber plate. This is consistent in Continuation reached, that an existing or necessary rake as far as possible the required and needed Cores for the design of the cylinder head includes.
In Weiterbildung der Erfindung ist die Brennraumplatte halbkugelförmig ausgebildet, wobei die kugelförmige Seite von dem Brennraum wegweist und die Gaswechselkanalwandungen aus der Brennraumplatte herauswachsend flanschförmig in Zylinderkopfwände münden. Durch die halbkugelförmige Ausbildung der Brennraumplatte ist eine leichte Entformbarkeit des Zylinderkopfes aus der Gießform gegeben. Zu dieser leichten Entformbarkeit trägt auch das Merkmal des Herauswachsens der Gaswechselkanalwandungen aus der Brennraumplatte bei.In Development of the invention, the combustion chamber plate is hemispherical in shape, being the spherical one Side points away from the combustion chamber and the Gaswechselkanalwandungen emerging from the combustion chamber plate in the form of a flange into cylinder head walls. By the hemispherical training the combustion chamber plate is a slight releasability of the cylinder head from the mold given. To this easy demolding also carries the feature of growing out the Gaswechselkanalwandungen from the combustion chamber plate at.
In Weiterbildung der Erfindung erstreckt sich ein aus der Brennraumplatte herauswachsender Balken angenähert mittig über der Brennraumplatte in Längsrichtung des Zylinderkopfes. Dabei sind in den Balken zwei Kühlmittelleitungen eingelassen. In weiterer Ausgestaltung weist der Balken zu der Zylinderkopfdeckelseite hin eine konti nuierlich oder absatzförmig abnehmende Breite auf. Der Balken trägt zu einer steifen Ausgestaltung des Zylinderkopfes bei und erfüllt mit der Aufnahme von Kühlmittelleitungen gleichzeitig Hilfsfunktionen. Dabei ist durch die gewählte Ausbildung und Anbindung des Balkens an die Brennraumplatte auch wieder die leichte Entformbarkeit gegeben.In Development of the invention extends from the combustion chamber plate approaching outgrowing beams in the middle over the combustion chamber plate in the longitudinal direction of the cylinder head. There are two coolant lines in the bar admitted. In a further embodiment, the beam to the cylinder head cover side towards a continu- ously or paragraph decreasing width. The beam carries to a rigid design of the cylinder head and satisfied with the intake of coolant lines at the same time Auxiliary functions. It is by the chosen training and connection the beam to the combustion chamber plate again the easy demolding given.
In weiterer Ausgestaltung sind Zylinderkopfschraubenpfeifen an den Eckpunkten der Brennraumplatte angeordnet, welche auf Höhe der Gaswechselkanalflanschoberkante mit der Zylinderkopfschraubenauflagefläche eine Ebene bilden. Dabei sind in weiterer Ausgestaltung die Zylinderkopfschraubenpfeifen über die Zylinderkopfbegrenzungswände (Stirn- und Seitenwände) trogförmig verbunden. Auch diese Ausbildung trägt zur leichten Entformbarkeit bei.In Further refinement are cylinder head screws on the Corner points of the combustion chamber plate arranged, which at the level of Gaswechselkanalflanschoberkante Make a plane with the cylinder head bolt support surface. There are in a further embodiment, the cylinder head screws on the Cylinder head boundary walls (Front and side walls) trough-shaped connected. This training also contributes to easy demolding at.
