Abstract
Description
Die Erfindung betrifft einen Nockenwellenversteller mit den Merkmalen des Oberbegriffs von Anspruch 1.The The invention relates to a camshaft adjuster with the features the preamble of claim 1.
Ein
derartig ausgebildeter Nockenwellenversteller ist zum Beispiel aus
der
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, einen möglichst kostengünstigen und zuverlässigen Nockenwellenversteller mit einer seitlichen Begrenzung der Lauffläche des Zugmitteltriebes auf dem Stator zu schaffen.outgoing From this prior art, the invention is based on the object the most cost-effective and reliable Camshaft adjuster with a lateral boundary of the tread to create the traction mechanism drive on the stator.
Die Lösung der Aufgabe erfolgt erfindungsgemäß dadurch, dass wenigstens eine der Dichtscheiben den Stator wenigstens abschnittsweise radial nach außen überragt. Der Vorteil der Erfindung ist darin zu sehen, dass die ohnehin vorhandene Dichtscheibe nur geringfügig anders bemessen werden muss, z. B. durch Wahl eines größeren Außendurchmessers und dadurch neben ihrer Dichtfunktion gleichzeitig die Funktion der bisher notwendigen Bordscheiben übernimmt. Dadurch entfällt jegliche zusätzliche bisher erforderliche spanende Bearbeitung des Stators und anschließende Befestigung der Bordscheibe, so dass die Kosten erheblich gesenkt werden. Ferner entfällt die bisher notwendige kritische Schweißverbindung, so dass zusätzlich die Funktionssicherheit des Nockenwellenverstellers im Dauerbetrieb wesentlich verbessert ist. Außerdem bietet die Erfindung den Vorteil, dass die Lauffläche des Stators für den Zugmitteltrieb nicht durch die an dem Stator zu befestigende Bordscheibe verkleinert wird.The The object is achieved according to the invention by that at least one of the sealing disks at least partially the stator projecting radially outwards. The advantage of the invention is to see that the already existing gasket only slightly must be measured differently, z. B. by choosing a larger Outer diameter and thus in addition to their sealing function at the same time the function of the previously required flanged wheels takes over. This eliminates any additional previously required machining of the stator and subsequent attachment the flange, so that the costs are lowered significantly. Further eliminates the previously required critical welded joint, so that in addition the functional safety of the camshaft adjuster is significantly improved in continuous operation. Also offers the invention has the advantage that the tread of the stator for the traction drive not through the on the stator too attaching flange is reduced.
Es wird weiter vorgeschlagen, dass die Dichtscheibe in dem den Stator überragenden Bereich Ausnehmungen aufweist. Die Ausnehmungen bieten den Vorteil einer Gewichtsersparnis, welche in modernen Fahrzeugen von den Fahrzeugherstellern aus ökologischen Gesichtspunkten inzwischen besonders gefordert wird. Die Ausnehmungen können als Löcher oder auch als Freischnitte aus dem Vollkreis der Dichtscheibe gebildet sein.It It is further proposed that the sealing disc in the projecting the stator Has area recesses. The recesses offer the advantage a weight saving, which in modern vehicles from the vehicle manufacturers from ecological Aspects is now particularly required. The recesses can look like holes or as free cuts be formed the full circle of the sealing disc.
Die den Stator überragende Dichtscheibe kann vorzugsweise aus einem Stanzteil gebildet sein, so dass der den Stator überragende Bereich und auch die vorgeschlagenen Ausnehmungen der Dichtscheibe beim Stanzen der Dicht scheibe gleich mit geformt werden können. Die zusätzliche Funktion der Dichtscheibe wird dadurch ohne nennenswerte Mehrkosten in der Dichtscheibe verwirklicht. Das Stanzteil sollte bevorzugt als Stahlstanzteil ausgebildet sein, so dass die Dichtscheibe sehr robust gegenüber den Dauerschwingbelastungen ist. Ferner besitzt ein Stahlstanzteil den Vorteil, dass bereits mit geringen Wandstärken eine robuste seitlich Begrenzung der Lauffläche erzielt werden kann.The the stator protruding sealing washer may preferably made be formed of a stamped part, so that the towering the stator Range and also the proposed recesses of the gasket when punching the sealing disc can be molded with the same. The additional function of the sealing disc is thereby realized without significant additional costs in the sealing washer. The stamped part should preferably be formed as a steel stamped part, so that the Sealing disc very robust against the fatigue loads is. Furthermore, a steel stamping has the advantage that already with low wall thicknesses a sturdy side boundary the tread can be achieved.
Insgesamt ergibt sich ein besonders einfacher und kostengünstiger Aufbau dann, wenn der Rotor und der Stator an der Seite an der die den Stator überragende Dichtscheibe anliegt in zusammengebauten Zustand eine ebene Oberfläche bilden. In diesem Fall kann auch die Dichtscheibe als ebene Scheibe ausgebildet werden, was besonders günstig hinsichtlich der Dichtfunktion und der Befestigung der Dichtscheibe ist. Da die Dichtscheibe an dem Stator befestigt ist und gegenüber diesem eine statische Dichtfunktion wahrnimmt, gleichzeitig aber an dem Rotor dynamisch dichtend anliegen muss, ohne die Verstellbewegung zu behindern, unterliegt die Dichtscheibe besonders hohen Anforderungen an die Formgenauigkeit, welche mit einer ebenen Dichtscheibe am leichtesten zu erfüllen sind.All in all This results in a particularly simple and cost-effective Build up when the rotor and the stator on the side of the the stator protruding sealing washer rests in assembled Condition to form a level surface. In this case can Also, the sealing disc can be formed as a flat disc, which Particularly favorable in terms of the sealing function and the Attachment of the sealing washer is. Since the gasket is attached to the stator is and perceives a static sealing function against this, at the same time, however, must be in a dynamically sealing manner on the rotor, without hindering the adjustment, subject to the sealing disc particularly high demands on the dimensional accuracy, which with a flat sealing washer are the easiest to fulfill.
Es wird weiter vorgeschlagen, dass der Stator eine Außenverzahnung aufweist, und die Dichtscheibe die Außenverzahnung wenigstens abschnittsweise seitlich überdeckt. Die Erfindung nutzt dabei die Erkenntnis, dass es zur seitlichen Sicherung des Zugmittels, wie z. B. einer Gliederkette oder eines Zahnriemens in einer Außenverzahnung, ausreicht, wenn die Dichtscheibe eben nur den Verzahnungsgrund überragt und dadurch das in die Verzahnung eingreifende Zugmittel seitlich sichert.It it is further suggested that the stator has an outer toothing has, and the sealing disc, the external teeth at least partially covered laterally. The invention uses the realization that it is necessary for the lateral securing of the traction device, such as B. a link chain or a toothed belt in an outer toothing, is sufficient if the sealing disk just surmounted only the Verzahnungsgrund and thereby the traction means engaging in the toothing laterally guaranteed.
Weiterhin wird vorgeschlagen, dass die Dichtscheibe ringförmige axial gerichtete Stufen aufweist. Dadurch wird die Dichtscheibe selbst versteift und kann auch für Nockenwellenversteller verwendet werden, in dem der Rotor und der Stator axial versetzt angeordnete Dichtflächen aufweisen und/oder der Bereich der Führung des Zugmittels seitlich versetzt zu einer Dichtfläche angeordnet ist.Farther It is suggested that the sealing disc be annular axial directed stages has. This will make the gasket itself stiffened and can also be used for camshaft adjuster, in which the rotor and the stator axially offset sealing surfaces and / or the area of guidance of the traction device is arranged laterally offset from a sealing surface.
Die Erfindung wird nachfolgend anhand eines bevorzugten Ausführungsbeispieles näher erläutert. Die Figur zeigt im Einzelnen:The invention will be explained in more detail below with reference to a preferred embodiment tert. The figure shows in detail:
