Abstract
Description
Die Erfindung betrifft einen Ventiltrieb für eine Brennkraftmaschine mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1.The invention relates to a valve train for an internal combustion engine with the features of the preamble of
Sie geht von der
Nachteilig an der bekannten Ausführungsform ist die relativ hohe Masse der Ventiltriebsbauteile, die die maximale Drehzahl der Brennkraftmaschine reduziert.A disadvantage of the known embodiment is the relatively high mass of the valve train components, which reduces the maximum speed of the internal combustion engine.
Aufgabe der vorliegenden Erfindung ist es eine Maßnahme aufzuzeigen, zur Verringerung der Masse der bewegten Ventiltriebsbauteile.Object of the present invention is to show a measure to reduce the mass of the moving valve train components.
Diese Aufgabe wird durch das Merkmal im kennzeichnenden Teil des Patentanspruchs 1 gelöst.This object is achieved by the feature in the characterizing part of
Durch die Darstellung des Spielausgleichselementes als separates Bauteil wird die dynamische Masse der Stößelstange deutlich reduziert, wodurch höhere Drehzahlen für die Brennkraftmaschine möglich sind. In vorteilhafter Weise wird mit dem „stehenden” Spielausgleichselement ein absolut spielfreier Ventiltrieb dargestellt.By presenting the lash adjuster as a separate component, the dynamic mass of the push rod is significantly reduced, whereby higher speeds for the internal combustion engine are possible. Advantageously, an absolutely backlash-free valve train is represented with the "standing" clearance compensation element.
Die Ausbildung gemäß Patentanspruch 2 ist eine besonders bevorzugte Ausführungsvariante, mit der nochmals die Massen reduziert werden können.The embodiment according to
Die Ausbildung gemäß Patentanspruch 3 ist ebenfalls eine besonders bevorzugte, Platz sparende Ausführungsvariante.The embodiment according to
Weiter ist besonders bevorzugt das Spielausgleichselement gemäß Patentanspruch 4 ein hydraulisches Spielausgleichselement.Further, the clearance compensation element according to
Durch die Ausbildung gemäß Patentanspruch 5 kann in vorteilhafter Weise auf eine separate hydraulische Versorgungsleitung verzichtet werden.Due to the design according to
Die Ausführung gemäß Patentanspruch 6 wirkt sich besonders gut auf das Package aus.The embodiment according to claim 6 has a particularly good effect on the package.
Im Folgenden ist die Erfindung anhand eines bevorzugten Ausführungsbeispieles in einer einzigen Figur näher erläutert.In the following the invention with reference to a preferred embodiment in a single figure is explained in more detail.
Erfindungsgemäß ist auf der, der Stößelstange
Das Spielausgleichselement
Weiter weist das Maschinengehäuse
Durch die erfindungsgemäße Ausgestaltung des Ventiltriebs
Vorteile der Erfindung: Advantages of the invention:
- – Mit der vorgeschlagenen Anordnung der Bauelemente kann der Zylinderkopf ab Oberkante Zylinderkopf sehr niedrig gehalten werden, woraus Packagevorteile resultieren;- With the proposed arrangement of the components, the cylinder head from the top of the cylinder head can be kept very low, resulting in package advantages;
- – es muss kein Bauraum für ein Kettenrad wie bei einer obenliegenden Nockenwelle berücksichtigt werden;- There is no space for a sprocket to be considered as an overhead camshaft;
-
– durch das oben, bevorzugt in der Zylinderkopfhaube eingesetzte Spielausgleichselement
6 , das nicht bewegt werden muss, können die restlichen Ventiltriebsbauteile sehr leicht ausgeführt werden, wodurch nur geringe Massen bewegt werden müssen und hohe Drehzahlen darstellbar sind;- By the above, preferably used in the cylinder head cover clearance compensation element6 , which does not need to be moved, the remaining valve train components can be made very easily, which only small masses must be moved and high speeds are displayed; -
– mit dem hydraulischen Spielausgleichselement
6 ist ein absolut spielfreier Ventiltrieb dargestellt.- with the hydraulic clearance compensation element6 is an absolutely backlash-free valve train shown.
