Description
Die Erfindung betrifft einen Verbrennungsmotor mit einem ein Kurbelwellengehäuse umfassenden Motorblock, mit einem am Motorblock vorgesehenen Zylinderkopf, wobei der Motorblock aus einem metallischen Material hergestellt ist. Ferner umfasst der Verbrennungsmotor entweder eine den Zylinderkopf abdeckende Abdeckhaube und/oder eine am Motorblock vorgesehene Ölwanne, und einen eine Steuerkette oder einen Keilreimen abdeckenden Steuerdeckel.The invention relates to an internal combustion engine with an engine block comprising a crankcase, with a cylinder head provided on the engine block, wherein the engine block is made of a metallic material. Furthermore, the internal combustion engine comprises either a cover covering the cylinder head and / or an oil sump provided on the engine block, and a control cover covering a timing chain or a wedge rime.
Abdeckhaube, Ölwanne und/oder Steuerdeckel werden in der Regel an dem Motorblock mittels Befestigungsschrauben angeschraubt. Zwischen dem Motorblock und der Abdeckhaube, der Ölwanne und/oder dem Steuerdeckel wird dazu eine den jeweiligen Anforderungen gerecht werdende Dichtung vorgesehen.Cover, oil pan and / or control cover are usually screwed to the engine block by means of fastening screws. Between the engine block and the cover, the sump and / or the control cover to a respective requirements expectant seal is provided.
Verbrennungsmotoren mit Merkmalen der Oberbegriffe der unabhängigen Ansprüche sind aus der
Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, einen Verbrennungsmotor zur Verfügung zu stellen, bei dem eine funktionssichere und insbesondere dichte Anordnung der Ölwanne und/oder der Abdeckhaube, sowie des Steuerdeckels am Motorblock bereit gestellt wird.The present invention is based on the object to provide an internal combustion engine available, in which a functionally reliable and particularly dense arrangement of the oil pan and / or the cover, and the control cover is provided on the engine block.
Diese Aufgabe wird mit einem Verbrennungsmotor gelöst, bei dem die Ölwanne und/oder die Abdeckhaube, sowie der Steuerdeckel aus Kunststoffmaterial hergestellt ist und bei dem der Motorblock einen Fügeabschnitt aufweist, der eine mittels eines Laser hergestellte strukturierte Oberfläche aufweist, wobei die Ölwanne und/oder die Abdeckhaube, sowie der Steuerdeckel einen Gegenabschnitt aufweist, der mit der strukturierten Oberfläche verzahnt ist, wobei die Verzahnung mittels thermischem Aufschmelzen des Gegenabschnitts hergestellt ist.This object is achieved with an internal combustion engine in which the oil sump and / or the cover, as well as the control cover made of plastic material and wherein the engine block has a joint portion having a structured surface produced by means of a laser, wherein the oil pan and / or the cover, as well as the control cover having a counter portion which is interlocked with the structured surface, wherein the toothing is made by means of thermal melting of the counter portion.
Es hat sich herausgestellt, dass derartige Verbindungen auf einfache Art und Weise hergestellt werden können, und dennoch fluiddicht sind und zudem vergleichsweise hohe Kräfte zwischen dem Metall-Bauteil und dem Kunststoff-Bauteil übertragen werden können. Eine Dichtung zwischen dem Motorblock und der Ölwanne und/oder der Abdeckhaube, sowie dem Steuerdeckel kann dazu entfallen. Die strukturierte Oberfläche weist dabei vorzugsweise eine räumliche Struktur auf, die insbesondere auch Hinterschneidungen aufweisen kann, die beim thermischen Aufschmelzen des Kunststoffs hintergriffen werden.It has been found that such connections can be made in a simple manner, and yet fluid-tight and also comparatively high forces between the metal component and the plastic component can be transmitted. A seal between the engine block and the oil pan and / or the cover, and the control cover can be omitted. The structured surface preferably has a spatial structure, which may in particular also have undercuts which are engaged behind during the thermal melting of the plastic.
Das Vorsehen eines Fügens mittels strukturierter Oberfläche und zugehöriger Verzahnung hat den Vorteil, dass eine unlösbare und dauerhaft dichte Verbindung bereit gestellt werden kann.The provision of joining by means of a structured surface and associated toothing has the advantage that an insoluble and permanently sealed connection can be provided.
Erfindungsgemäß ist eine den Zylinderkopf abdeckende Abdeckhaube vorgesehen. Die Abdeckhaube weist dabei eine umlaufende Anlagefläche, die als Gegenabschnitt ausgebildet ist, auf. Der Motorblock weist an seiner Oberseite eine entsprechend ausgebildete Anlagefläche für die Abdeckhaube auf, die als Fügeabschnitt ausgebildet ist. Insgesamt kann eine optimale Verbindung der Abdeckhaube am Motorblock gewährleistet werden, wobei diese Verbindung auch hohen, innerhalb des Zylinderkopfs herrschenden Temperaturen und Drücken Stand halten kann.According to the invention, a cover covering the cylinder head is provided. The cover has a circumferential contact surface, which is designed as a counter section, on. The engine block has on its upper side a correspondingly formed bearing surface for the cover, which is designed as a joint section. Overall, an optimal connection of the cover on the engine block can be ensured, and this connection can also hold high, prevailing within the cylinder head temperatures and pressures.
Alternativ oder zusätzlich ist eine Ölwanne vorgesehen, die eine den Zylinderkopf abgewandte Seite des Motorblocks wenigstens abschnittsweise abdeckt. Die Ölwanne kann sich auch über die gesamte Unterseite des Motorblocks erstrecken. Die Ölwanne weist einen umlaufenden, am Motorblock anliegenden Gegenabschnitt auf, der mit einem am Motorblock vorgesehenen, mit dem Gegenabschnitt zusammenwirkenden Fügeabschnitt verzahnt ist. Auch hierdurch kann eine sichere Verbindung hergestellt werden, die hohe Temperaturen und auch hohe Drücke aushält.Alternatively or additionally, an oil pan is provided which covers a side of the engine block facing away from the cylinder head at least in sections. The oil pan can also extend over the entire bottom of the engine block. The oil sump has a circumferential, on the engine block abutting portion which is toothed with a provided on the engine block, cooperating with the mating section joining portion. This also makes it possible to produce a secure connection that can withstand high temperatures and high pressures.
Ferner ist ein eine Steuerkette oder einen Keilriemen abdeckender Steuerdeckel vorgesehen. Der Steuerdeckel dient dabei insbesondere den Motor von seiner Vorderseite her abzudecken. Der Steuerdeckel kann sich dabei nicht nur über den Motorblock, sondern auch abschnittsweise über die Ölwanne und/oder die Abdeckhaube erstrecken. Insbesondere dann, wenn verschiedene Bauteile aneinander angrenzen, die ein sogenanntes, dichtungstechnisch problematische ”Dreiländereck” ausbilden, kann durch die Verzahnung der Bauteile mittels thermischem Aufschmelzen des Gegenabschnitts des Kunststoff-Bauteils eine dichte Verbindung bereitgestellt werden.Further, a control chain or a V-belt covering the control cover is provided. The control cover is used in particular to cover the engine from its front side. The control cover can not only extend over the engine block, but also in sections over the oil pan and / or the cover. In particular, when different components adjacent to each other, which form a so-called, sealing problematic "tri-border triangle" can be provided by the teeth of the components by means of thermal melting of the counterpart portion of the plastic component, a tight connection.
Die Abdeckhaube als solches kann eine in der Abdeckhaube vorgesehene, insbesondere dicht verschließbare Revisionsöffnung aufweisen. Die Revisionsöffnung kann dazu dienen, um auf den von der Abdeckhaube umschlossenen Bereich zugreifen zu können.As such, the cover can have an inspection opening provided in the cover, in particular, a sealable closure. The inspection opening can serve to access the area enclosed by the cover hood.
Vorteilhafterweise kann der Motorblock aus einer Aluminiumlegierung hergestellt sein; insbesondere auch bei einer solchen Legierung kann eine Verzahnung mittels thermischem Aufschmelzen funktionssicher bereitgestellt werden.Advantageously, the engine block may be made of an aluminum alloy; In particular, even with such an alloy, a toothing can be provided functionally reliable means of thermal melting.
Weitere Einzelheiten und vorteilhafte Ausgestaltungen der Erfindung sind der nachfolgenden Beschreibung zu entnehmen, anhand derer ein Ausführungsbeispiel der Erfindung näher beschrieben und erläutert ist.Further details and advantageous embodiments of the invention will become apparent from the following description, with reference to which an embodiment of the invention is described and explained in detail.
