Abstract
Description
Die Erfindung bezieht sich auf ein Abdeckgehäuse für eine Brennkraftmaschine nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to a cover housing for an internal combustion engine the preamble of claim 1.

Es ist Aufgabe der Erfindung ein Abdeckgehäuse für eine Brennkraftmaschine in Form eines Ventildeckels zu schaffen, an dem hochwirksame und leicht umsetzbare Maßnahmen zur Geräuschreduktion vorgesehen sind.It The object of the invention is a cover housing for an internal combustion engine Shape of a valve cover to create on the highly effective and easy actionable measures for noise reduction are provided.
Nach der Erfindung wird diese Aufgabe durch die Merkmale des Patentanspruchs gelöst. Weitere die Erfindung ausgestaltende Merkmale sind in den Unteransprüchen enthalten.To The invention achieves this object by the features of the patent claim solved. Further the invention ausgestaltende features are included in the subclaims.
Die mit der Erfindung hauptsächlich erzielten Vorteile sind darin zu sehen, dass durch gezielte Ausbildung der geräuschmindernden als eine Wandverdickung mit Sicken ausgebildeten Einrichtung lediglich im Bereich von einer Geräuschquelle bspw. von einem Steuertrieb einer Nockenwelle störende Klangemissionen zumindest reduziert werden. Zusätzlich zu der Wandverdickung wird der Ventildeckel aufgrund der Wölbungen und der konkaven Fläche verstärkt, wodurch sein Geräuschverhalten verbessert wird. Die Rippen an der Außenseite der Wandverdickung sind auf einfache Weise realisierbar und können zur Erzielung besonderer ästhetischer Wirkungen entsprechend gestaltet werden. Schließlich bietet sich an, die Wandverdickung aus einem Stück mit dem Ventildeckel herzustellen, wobei allerdings für entsprechende Anwendungsfälle auch denkbar ist, die Wandverdickung als ein vom Ventildeckel getrennt hergestelltes Bauteil auszubilden, das dann durch Kleben, Schrauben oder dgl. mit besagtem Ventildeckel verbindbar ist.The with the invention mainly The benefits achieved can be seen in the fact that through targeted training the noise-reducing as a wall thickening formed with beads device only in the range of a noise source For example, from a Steuervieb a camshaft disturbing sound emissions at least be reduced. In addition to the wall thickening is the valve cover due to the bulges and the concave surface strengthened causing his noise behavior is improved. The ribs on the outside of the wall thickening are easily realizable and can achieve a special aesthetic Effects are designed accordingly. Finally, offers itself, the wall thickening out of one piece to produce with the valve cover, although for appropriate use cases It is also conceivable, the wall thickening as a separate from the valve cover formed component, which then by gluing, screws or the like. With said valve cover is connectable.
In der Zeichnung wird ein Ausführungsbeispiel der Erfindung gezeigt, das nachstehend näher erläutert wird.In The drawing is an embodiment of the invention, which is explained in more detail below.
