Abstract
Description
Die Erfindung betrifft gemäß dem Oberbegriff von Patentanspruch 1 einen Schwenkmotorversteller. The invention relates according to the preamble of claim 1 a Schwenkmotorversteller.
Die
Aus der
Aufgabe der Erfindung ist es, einen dichten zahnriemengetriebenen Schwenkmotorversteller für eine Nockenwelle zu schaffen. The object of the invention is to provide a dense toothed belt driven Schwenkmotorversteller for a camshaft.
Diese Aufgabe wird erfindungsgemäß mit den Merkmalen von Patentanspruch 1 gelöst. This object is achieved with the features of
Gemäß einem Vorteil der Erfindung ist das Hydraulikventil des Schwenkmotorverstellers als Zentralventil innerhalb einer Zentralschraube ausgeführt. Eine solche Zentralventil hat Bauraumvorteile. Außer Zentralventilen gibt es noch die externen Hydraulikventile zur Betätigung des Schwenkmotorverstellers. Beim externen Hydraulikventil verlaufen die Hydraulikkanäle zur Nockenwellenverstellung vom Schwenkmotorversteller zu einem gesonderten Steuertriebdeckel mit dem dort eingeschraubten Hydraulikventil oder aber zum Zylinderkopf mit dem dort eingeschraubten Hydraulikventil. Mit den hydraulischen Leitungen vom Schwenkmotorversteller zum externen Hydraulikventil gehen Leitungsverluste einher. Zudem werden die Steuerungen von externen Hydraulikventil nicht so dynamisch umgesetzt, wie beim Zentralventil. Das ebenfalls hydraulische Zentralventil ist radial innerhalb der Rotornabe des Schwenkmotorverstellers angeordnet. According to an advantage of the invention, the hydraulic valve of the Schwenkmotorverstellers is designed as a central valve within a central screw. Such a central valve has space advantages. In addition to central valves, there are the external hydraulic valves for actuating the Schwenkmotorverstellers. In the external hydraulic valve, the hydraulic passages for adjusting the camshaft from Schwenkmotorversteller to a separate Steuertriebdeckel with the screwed there hydraulic valve or to the cylinder head with the screwed there hydraulic valve. The hydraulic lines from the swivel motor adjuster to the external hydraulic valve are associated with line losses. In addition, the controls of external hydraulic valve are not implemented as dynamic as the central valve. The likewise hydraulic central valve is arranged radially inside the rotor hub of the Schwenkmotorverstellers.
Zahnriemengetriebe Statoren bzw. Nockenwellen bieten gegenüber dem Kettengetrieb den Vorteil eines ruhigen Laufes. Überdies sind Zahnriemen leichter und kostengünsitger. Eine Schmierung ist nicht notwendig – bei Standard-Zahnriemen aber auch nicht erwünscht. Toothed belt transmissions Stators or camshafts offer the advantage over the chain drive of a quiet running. Moreover, timing belts are lighter and more cost effective. Lubrication is not necessary - with standard timing belts but also not desirable.
In besonders vorteilhafter Weise ist der Zapfen axial verschiebbar gegenüber der Stangendichtung geführt. In a particularly advantageous manner, the pin is guided axially displaceable relative to the rod seal.
Die Stangendichtung kann ein Profil mit Schrägen oder ein Profil mit einer ausgerundeten Wölbung aufweisen. Damit wird zum einen erreicht, dass die Stangendichtung eine radiale Weichheit hat, die Koaxialitätsfehler des Zapfens ausgleichen kann. Zum anderen kann die Stangendichtung unter einer Vorspannung radial am Zapfen anliegen. The rod seal can have a profile with bevels or a profile with a rounded curvature. This is achieved on the one hand, that the rod seal has a radial softness that can compensate for Koaxialitätsfehler the pin. On the other hand, the rod seal can bear radially on a pin under a bias.
Der Kolben ist in einer besonders vorteilhaften Ausgestaltung komplett druckausgeglichen. The piston is completely pressure balanced in a particularly advantageous embodiment.
In einer besonders vorteilhaften Ausgestaltung stützt das selbe Spannelement die Buchse in den beiden axialen Richtungen ab. In a particularly advantageous embodiment, the same clamping element supports the bushing in the two axial directions.
Weitere Vorteile der Erfindung gehen aus den weiteren Patentansprüchen, der Beschreibung und der Zeichnung vor. Further advantages of the invention will become apparent from the other claims, the description and the drawings.
Die Erfindung ist nachfolgend anhand von zwei Ausführungsbeispielen näher erläutert. The invention is explained in more detail below with reference to two exemplary embodiments.
