Description
Gebiet der ErfindungField of the invention
Die Erfindung betrifft einen druckmittelbetriebenen Nockenwellenversteller gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a fluid-operated camshaft adjuster according to the preamble of claim 1.
Aus
der
Aufgabe der Erfindung ist es, einen gattungsgemäßen Nockenwellenversteiler mit einem vereinfachten Aufbau zu schaffen.task The invention is a generic camshaft distributor to create with a simplified structure.
Zur Lösung der Aufgabe wird gemäß Anspruch 1 vorgeschlagen, dass die Klemmkörper eines Freilaufes einheitlich in eine Richtung verriegelbar ausgebildet sind, und an dem Rotor zwischen einer ersten Verriegelungsstellung, in der der Rotor und der Stator miteinander gekoppelt sind, und einer zweiten Freigabestellung, in der der Rotor und der Stator entkoppelt sind, schwenkbar gelagert sind, und mittels jeweils eines Federelementes in Richtung Verriegelungsstellung federbelastet sind. Die Klemmkörper eines Freilaufes sind damit entgegen der im Stand der Technik vorgesehenen beidseitigen Klemmbarkeit bewusst nur in eine Richtung klemmbar ausgebildet, wodurch sich der Aufbau des Nockenwellenverstellers erheblich vereinfacht. Zur Rückstellung des Rotors gegenüber dem Stator werden dabei die bisher als nachteilig gesehenen Wechselmomente der Nockenwelle genutzt. Diese werden erzeugt durch das periodische Öffnen und Schließen der Gaswechselventile durch die Nockenwelle und durch die aus dem Kurbelwellentrieb resultierenden hochfrequenten Drehschwingungen, verursacht durch die schwankende Größe und den stark unterschiedlichen zeitlichen Verlauf der Gaskräfte in den Zylindern des Verbrennungsmotors. Aufgrund der vorgeschlagenen Lösung muss nunmehr nur noch eine der Verstellkammern mit Druck beaufschlagbar ausgebildet sein, wodurch sich der konstruktive Aufbau des Nockenwellenverstellers insgesamt weiter wesentlich vereinfacht. Eine kontrollierte Rückstellbewegung kann z. B. dadurch erreicht werden, indem der Arbeitsdruck in der während der Zustellbewegung druckmittelbeaufschlagten Verstellkammer gesteuert wird.to Solution of the problem is in accordance with claim 1 suggested that the clamp body of a freewheel are formed uniformly lockable in one direction, and on the rotor between a first locking position, in the the rotor and the stator are coupled together and a second one Release position in which the rotor and the stator are decoupled, are pivotally mounted, and by means of a respective spring element are spring loaded in the direction of locking position. The clamp body a freewheel are thus contrary to those provided in the prior art two-sided clamping intentionally clamped in one direction only formed, whereby the structure of the camshaft adjuster considerably simplified. To reset the rotor opposite The stator is the previously seen as disadvantageous alternating moments the camshaft used. These are generated by the periodic opening and closing the gas exchange valves by the camshaft and by the resulting from the crankshaft drive high-frequency Torsional vibrations caused by the fluctuating size and the very different temporal course of the gas forces in the cylinders of the internal combustion engine. Due to the proposed Solution must now only one of the adjustment chambers with Be formed acted upon pressure, whereby the constructive Overall construction of the camshaft adjuster considerably simplified. A controlled return movement can, for. B. thereby be achieved by the working pressure in the during the Zustellbewegung controlled by pressure medium adjustment chamber becomes.
Ein besonders einfacher Aufbau ergibt sich dadurch, dass die Federelemente zwischen den Klemmkörpern und den Flügeln angeordnet sind, und die Klemmkörper in der die Hydraulikräume radial innenseitig begrenzenden Rotorfläche gelagert sind. Damit ergibt sich insgesamt ein einfacher konstruktiver Aufbau und eine stabile Abstützfläche sowohl für die Federelemente als auch für die Klemmkörper.One a particularly simple structure results from the fact that the spring elements arranged between the clamping bodies and the wings are, and the clamping body in the hydraulic chambers are mounted radially inwardly limiting rotor surface. In order to overall results in a simple structural design and a stable support surface for both Spring elements as well as for the clamping body.
Es wird weiter vorgeschlagen, dass die Klemmkörper im Querschnitt kreissegmentartig ausgebildet sind, und mit ihrer radial nach innen gerichteten Spitze am Rotor gelagert sind, und die Abstände der beiden radial außen liegenden Spitzen zum Drehpunkt der Klemmkörper unterschiedlich sind. Die vorgeschlagene geometrische Form der Klemmkörper stellt eine besonders einfache Möglichkeit dar, eine einheitlich nur in eine Richtung wirkende Verriegelung zu schaffen, wobei für die Ver- und Entriegelung jeweils nur eine Schwenkbewegung erforderlich ist.It it is further proposed that the clamping body in cross section are formed circular segment-like, and with their radially inward directed tip are mounted on the rotor, and the distances the two radially outer tips to the fulcrum the clamp body are different. The proposed geometric shape of the clamp body makes a special simple way, a uniform only in one Directional locking to create, where for the Locking and unlocking only one pivoting movement is required.
Weiter wird vorgeschlagen, dass der Abstand von den den Flügeln zugewandten Spitzen der Klemmkörper zu dem Drehpunkt größer ist als der Abstand von den den Flügeln abgewandten Spitzen der Klemmkörper zu deren Drehpunkt. Die Klemmkörper verriegeln dadurch, indem sie eine Schwenkbewegung weg von den Flügeln ausführen. Wegen dieser Verriegelungsrichtung ist es sichergestellt, dass diese die Verriegelungsstellung erreichen können, ohne durch einen Anschlag in der Auslenkung begrenzt zu sein.Further It is suggested that the distance from the wings facing tips of the clamp body to the pivot greater is as the distance from the tips facing away from the wings of the Clamping body to the fulcrum. The clamp body lock by doing a pivoting movement away from the wings To run. Because of this locking direction, it is ensured that these can reach the locked position without to be limited by a stop in the deflection.
Es wird weiter vorgeschlagen, dass die Klemmkörper in Umfangsrichtung an den Flügeln angeordnet sind, und die Auslenkung der Klemmkörper bei der Schwenkbewegung in die Freigabestellung durch die Anlage an den Flügeln begrenzt ist. Damit ist sichergestellt, dass der für das Entriegeln des Freilaufs aufgebaute Druck in der Verstellkammer möglichst direkt in eine Verstellbewegung der Nockenwelle umgewandelt wird, wobei durch die Anlage der Klemmkörper an den Flügeln eine direkte Kraftübertragung unter Überbrückung der Federelemente sichergestellt ist.It It is further proposed that the clamping body in the circumferential direction are arranged on the wings, and the deflection of the Clamping body during the pivoting movement in the release position by the system is limited to the wings. This ensures that built up for unlocking the freewheel pressure in the adjustment as directly as possible in an adjustment the camshaft is converted, whereby by the system of the clamping body on the wings a direct power transmission with bridging the spring elements is ensured.
Es wird weiter vorgeschlagen, dass die Klemmkörper jeweils benachbarter Freiläufe in unterschiedlicher Richtung verriegeln. Dadurch ergibt sich der Vorteil, dass der Rotor bei fehlendem Druckmittel in jedem Fall in einer beliebigen Stellung gegenüber dem Stator verriegelt und ein fester Verbund geschaffen ist. Ferner können die aneinander angrenzenden Arbeitskammern unterschiedlicher Hydraulikräume in diesem Fall eine gemeinsame Druckmittelzufuhr aufweisen, so dass für die Verstellung des Rotors gegenüber dem Stator nur zwei Gruppen von Arbeitskammer mit Druckmittel beaufschlagt werden müssen. Dies bietet außerdem den Vorteil, dass die bisher nachteiligen Verluste an Druckmittel an den Dichtungen der Lagersegmente gegenüber dem Rotor nunmehr entfallen. Ferner ist es möglich nur die den Rotor in Verstellrichtung treibenden Arbeitskammer mit Druckmittel zu beaufschlagen, wobei dann die an den Lagersegmenten bewusst in Kauf genommene Leckage lediglich zur Entriegelung des benachbarten Freilaufes genutzt wird.It is further proposed that the clamping body of each adjacent freewheels lock in different directions. This results in the advantage that the rotor is locked in any case in any position relative to the stator in the absence of pressure medium and a solid bond is created. Further, the adjoining working chambers of different hydraulic chambers may in this case have a common pressure medium supply, so that only two groups of working chamber with pressure medium must be applied for the adjustment of the rotor relative to the stator. This also has the advantage that the previously disadvantageous losses of pressure medium to the seals of the bearing segments relative to the rotor now accounts. Furthermore, it is possible only the rotor driving in the direction of adjustment working chamber to pressurize with pressure medium, in which case the deliberately accepted in the bearing segments leakage is used only for unlocking the adjacent freewheel.
Nachfolgend wird die Erfindung anhand eines bevorzugten Ausführungsbeispieles näher erläutert. In den Figuren ist im Einzelnen zu erkennen:following The invention is based on a preferred embodiment explained in more detail. In the figures is in detail to recognize:
