Description
Die Erfindung betrifft einen Nockenwellenversteller für eine Brennkraftmaschine nach dem Oberbegriff des Anspruchs 1.The invention relates to a camshaft adjuster for an internal combustion engine according to the preamble of
Zur Senkung des Kraftstoffverbrauchs und der Rohemissionen sowie zur Erhöhung von Leistung und Drehmoment sind Ottomotoren in der Regel mit Nockenwellenverstellern ausgestattet. Diese verändern die Phasenlage der Nockenwelle relativ zur Kurbelwelle. Derzeit kommen meist hydraulische Flügelzellenversteller mit Arbeitskammern zum Einsatz. Die Verstellung wird durch den gesteuerten Eintritt von Öl aus dem Motorkreislauf über ein Steuerventil in die Kammern der Flügelzellen vorgenommen. Das Steuerventil wird durch eine elektromagnetische Einrichtung bewegt.To reduce fuel consumption and raw emissions and to increase power and torque, gasoline engines are usually equipped with camshaft adjusters. These change the phasing of the camshaft relative to the crankshaft. At present, mostly hydraulic vane-type adjusters with working chambers are used. The adjustment is made by the controlled entry of oil from the engine circuit via a control valve in the chambers of the vane. The control valve is moved by an electromagnetic device.

Zum allgemeinen technischen Hintergrund wird noch auf die
Der Erfindung liegt die Aufgabe zugrunde, einen Nockenwellenversteller für eine Brennkraftmaschine zu schaffen, der bei leichter und kostengünstiger Herstellbarkeit sowie zeit- und kostensparender Montage des Nockenwellenverstellers hohe Stellgeschwindigkeiten zur Veränderung der Phasenlage der Nockenwelle ermöglicht.The invention has for its object to provide a camshaft adjuster for an internal combustion engine, which allows for easy and cost manufacturability and time-saving and cost-effective installation of the camshaft adjuster high positioning speeds for changing the phase angle of the camshaft.
Diese Aufgabe wird erfindungsgemäß durch die im Patentanspruch 1 angegebenen Merkmale gelöst.This object is achieved by the features specified in
Ein wesentlicher Vorteil der Erfindung liegt in der Art der Verbindung des Ölführungsmoduls mit der Nockenwelle. Der Einsatz eines Ölführungsmoduls ergibt einen Nockenwellenversteller mit deutlich verbesserten Funktionseigenschaften insbesondere hinsichtlich der Verstellgeschwindigkeiten. Dadurch, dass das Ölführungsmodul in die Nockenwelle eingepresst wird, kann auf Schraubverbindungen verzichtet werden, wodurch die Betriebssicherheit zunimmt. Der Nockenwellenversteller kann dadurch nicht nur kleiner ausfallen, sondern auch leichter und preiswerter. Ein weiterer Vorteil ergibt sich daraus, dass das Ölführungsmodul zusätzlich zur Aufnahme weiterer Bauteile, wie beispielsweise einem Rückschlagventil und/oder einem Filter dienen kann. Hierdurch reduziert sich der Bauraumaufwand bezüglich Aufnahme von weiteren Bauteilen.A significant advantage of the invention lies in the nature of the connection of the oil guide module with the camshaft. The use of an oil guide module results in a camshaft adjuster with significantly improved functional properties, in particular with regard to the adjustment speeds. The fact that the oil guide module is pressed into the camshaft, can be dispensed with screw, whereby the reliability increases. The camshaft adjuster can not only be smaller, but also lighter and cheaper. Another advantage results from the fact that the oil guide module can additionally serve to accommodate other components, such as a check valve and / or a filter. This reduces the space required for receiving additional components.
Bei einigen Motoren ist es möglich, dass sich ein Nockenwellenlager zwischen Nockenwellenversteller und elektromagnetischer Einrichtung befindet. Vorteilhafterweise kann dieses Nockenwellenlager mit wenig Aufwand durch eine Verlängerung der Hydraulikmittelversorgung des Steuerventils mit Hydraulikmittel mitversorgt werden. Es ist aber auch möglich, die Versorgung des Lagers über eine separate Hydraulikmittelleitung vorzusehen.In some engines, it is possible for a camshaft bearing to be located between the phaser and the electromagnetic device. Advantageously, this camshaft bearing can be co-supplied with hydraulic fluid with little effort by an extension of the hydraulic fluid supply to the control valve. But it is also possible to provide the supply of the bearing via a separate hydraulic supply line.
Vorteilhafterweise ermöglicht es eine Rückstellfeder bei entsprechender Auslegung, die Reibung der Nockenwelle zu kompensieren und/oder den Nockenwellenversteller im drucklosen Zustand in eine bestimmte Position zu bringen.Advantageously, allows a return spring with a corresponding design to compensate for the friction of the camshaft and / or bring the camshaft adjuster in the unpressurized state in a particular position.
Vorteilhafterweise können die Gehäuse von Steuerventil und Ölführungsmodul in einem Bauteil zusammengefasst werden, wodurch sich der Aufwand an Einzelbauteilen reduziert.Advantageously, the housing of the control valve and oil guide module can be combined in one component, which reduces the cost of individual components.
Weitere Ausgestaltungen und Vorteile der Erfindung gehen aus den übrigen Unteransprüchen und der Beschreibung hervor.Further embodiments and advantages of the invention will become apparent from the remaining dependent claims and the description.
