Abstract
Description
Die Erfindung betrifft einen Nockenwellenversteller für eine Brennkraftmaschine nach dem Oberbegriff des Anspruchs 1.The The invention relates to a camshaft adjuster for an internal combustion engine according to the preamble of claim 1.
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 Reduction of fuel consumption and raw emissions as well as increase Performance and torque are gasoline engines usually with camshaft phasers fitted. These change the phase angle of the camshaft relative to the crankshaft. Currently usually come hydraulic vane positioner with working chambers used. The adjustment is controlled by the Entry of oil out of the engine cycle over a control valve made in the chambers of the vane. The control valve is moved by an electromagnetic device.

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.Of the Invention is based on the object, a camshaft adjuster for one To create an internal combustion engine that is lighter and less expensive Manufacturability and time and cost-saving installation of the camshaft adjuster high actuating speeds for changing the phase position of Camshaft allows.
Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Patentanspruchs 1 gegebenen Merkmale gelöst.These The object is achieved by the dissolved in the characterizing part of claim 1 given characteristics.
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.One The essential advantage of the invention lies in the type of 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, especially with regard to the adjustment speeds. Due to the fact that the oil guide module is pressed into the camshaft, can screwed on be waived, whereby the reliability increases. The camshaft adjuster It can not only be smaller, but also lighter and cheaper. Another advantage arises from the fact that the oil guide module additionally for receiving other components, such as a check valve and / or a filter can serve. This reduces the Space expenditure regarding Recording of other 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.at some engines it is possible that a camshaft bearing between camshaft adjuster and electromagnetic device is located. advantageously, Can this camshaft bearing with little effort by extending it the hydraulic fluid supply of the control valve with hydraulic fluid be taken care of. But it is also possible to supply the camp via a provide separate hydraulic medium 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 there is a return spring with appropriate design, to compensate for the friction of the camshaft and / or the camshaft adjuster in the unpressurized state in a to bring certain position.
Vorteilhafterweise können die Gehäuse von Steuerventil und Ölführungsmodul in einem Bauteil zusammengefasst werden, wodurch sich der Aufwand an Einzelbauteilen reduziert.advantageously, can the housings from control valve and oil guide module be summarized in one component, thereby reducing the effort reduced to 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 other dependent claims and the description.
