Abstract
Description
Gebiet der ErfindungField of the invention
Die Erfindung betrifft einen Nockenwellenversteller nach den Merkmalen der Oberbegriffs des Anspruchs 1.The invention relates to a camshaft adjuster according to the features of the preamble of claim 1.
Hintergrund der ErfindungBackground of the invention
Nockenwellenversteller werden in Verbrennungsmotoren zur Variation der Steuerzeiten der Brennraumventile eingesetzt. Die Anpassung der Steuerzeiten an die aktuelle Last senkt den Verbrauch und die Emissionen. Eine verbreitete Bauart ist der Flügelzellenversteller. Flügelzellenversteller weisen einen Stator, einen Rotor und ein Antriebsrad auf. Der Rotor ist meist mit der Nockenwelle drehfest verbunden. Der Stator und das Antriebsrad werden ebenfalls untereinander verbunden, wobei sich der Rotor koaxial zum Stator und innerhalb des Stators befindet. Rotor und Stator prägen Ölkammern aus, welche durch Öldruck beaufschlagbar sind und eine Relativbewegung zwischen Stator und Rotor ermöglichen. Weiterhin weisen die Flügelzellenversteller diverse Abdichtdeckel auf. Der Verbund von Stator, Antriebsrad und Abdichtdeckel wird über mehrere Schraubenverbindungen ausgebildet.Camshaft adjusters are used in internal combustion engines for varying the timing of the combustion chamber valves. Adjusting the timing to the current load lowers fuel consumption and emissions. A common type is the Flügelzellenversteller. Vane adjusters include a stator, a rotor and a drive wheel. The rotor is usually non-rotatably connected to the camshaft. The stator and the drive wheel are also interconnected with the rotor coaxial with the stator and within the stator. Rotor and stator characterize oil chambers, which can be acted upon by oil pressure and allow a relative movement between the stator and rotor. Furthermore, the vane cell adjusters have various sealing lids. The composite of stator, drive wheel and sealing cover is formed by a plurality of screw connections.

Zusammenfassung der ErfindungSummary of the invention
Aufgabe der Erfindung ist es, einen Nockenwellenversteller mit einer verbesserten Entlüftung zu schaffen.The object of the invention is to provide a camshaft adjuster with improved ventilation.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale im Anspruch 1 gelöst.According to the invention, this object is solved by the features in claim 1.
In einer Ausbildung der Erfindung ist die Durchgangsöffnung als Entlüftung für den Ölraum ausgebildet. Durch Montage und Betrieb des Nockenwellenverstellers sammeln sich Schmutz, Luft und ölfremde Stoffe in dem genannten Ölraum an. Diese Stoffe werden durch die Durchgangsöffnung dem Ölkreislauf im Motor rückgeführt und recycelt. Die Durchgangsöffnung führt dabei diese Stoffe vom Ölraum durch eine Durchgangsöffnung im Rotor zu der Nabe des Antriebsrades, wobei ein Spalt zwischen Nabe und einer Aufnahme des Antriebsrades ausgebildet ist, der in den Zylinderkopf mündet. Dabei ist diese Ausführung bevorzugt, um eine hoch integrative Entlüftung zu schaffen.In one embodiment of the invention, the passage opening is designed as a vent for the oil space. Through assembly and operation of the camshaft adjuster, dirt, air and oil-foreign substances accumulate in said oil space. These substances are recycled through the port to the oil circuit in the engine and recycled. The passage opening leads these substances from the oil chamber through a passage opening in the rotor to the hub of the drive wheel, wherein a gap between the hub and a receptacle of the drive wheel is formed, which opens into the cylinder head. In this case, this embodiment is preferred in order to create a highly integrative vent.
Eine Ausgestaltung der Erfindung bildet die Durchgangsöffnung als Bohrung aus. Im Einzelnen kommen Durchgangsbohrungen in Betracht, die den Ölraum mit der Nabe des Antriebsrades verbinden. Bohrungen können leicht spanend gefertigt werden, wobei ebenso Verfahren wie Sintern, Stanzpaketieren etc. zum Einsatz kommen können. Durchgangsöffnungen können jeden beliebigen Querschnitt aufweisen, welche entlang der Durchgangsöffnung konstant oder variabel gestaltet werden kann.An embodiment of the invention forms the passage opening as a bore. In particular, through holes are possible that connect the oil chamber with the hub of the drive wheel. Holes can be easily machined, and methods such as sintering, stamping, etc. can be used. Through openings can have any desired cross-section, which can be made constant or variable along the passage opening.
Eine detaillierte Ausgestaltung der Erfindung sind die als Bohrung ausgebildete Durchgangsöffnung und die Drehachse des Nockenwellenverstellers windschief angeordnet. Windschief beinhaltet jede Lage der beiden Achsen zueinander, außer, dass diese sich miteinander schneiden.A detailed embodiment of the invention, the bore formed as a through hole and the axis of rotation of the camshaft adjuster are skewed. Windfall includes any position of the two axes to each other, except that they intersect.
Eine weitere Detaillierung der Erfindung weist eine Durchgangsöffnung als Bohrung auf, dessen Achse sich mit der Drehachse des Nockenwellenverstellers schneidet. Dabei kann die Bohrung schräg oder orthogonal zur Drehachse angeordnet sein, bzw. jeden beliebigen Winkel einnehmen. Vorteilhafterweise unterstützt durch eine schräge Anordnung der Bohrung die Fliehkraft das Fördern der Stoffe.A further detail of the invention has a passage opening as a bore whose axis intersects with the axis of rotation of the camshaft adjuster. In this case, the bore may be arranged obliquely or orthogonally to the axis of rotation, or occupy any angle. Advantageously, supported by an oblique arrangement of the bore, the centrifugal force conveying the substances.
Eine weitere Ausgestaltung der Erfindung sieht vor, dass ein im Rotor angeordneter Verriegelungsmechanismus über diese Durchgangsöffnung entlüftet wird. Dabei bildet die Entlüftung des Verriegelungsmechanismus ein zusätzliches Feature zur erfindungsgemäßen Entlüftung und wird in diese integriert. Hierbei ist vorteilhaft, dass keine zusätzlichen Durchgangsöffnungen bei drehachsennah angeordneten Verriegelungsmechanismen gefertigt werden müssen.A further embodiment of the invention provides that a locking mechanism arranged in the rotor is vented via this passage opening. In this case, the venting of the locking mechanism forms an additional feature for venting according to the invention and is integrated in this. It is advantageous that no additional through holes must be made at drehachsennah arranged locking mechanisms.
