Description
Die Erfindung betrifft einen Nockenwellenversteller mit Riemenantrieb mit den Merkmalen des Oberbegriffs von Anspruch 1.The The invention relates to a camshaft adjuster with belt drive with the features of the preamble of claim 1.
Nockenwellenversteller werden in der Fachwelt nach einer üblichen Kategorisierung in zwei Klassen eingeteilt, Nockenwellenversteller mit Kettenantrieb und Nockenwellenversteller mit Riemenantrieb. Der Nockenwellenversteller wird von einer Kurbelwelle über den Riemen oder die Kette angetrieben und hat die Aufgabe, die Öffnungs- und Schließzeiten der Gaswechselventile einer Brennkraftmaschine zu verstellen. Durch die Verstellung der Öffnungs- und Schließzeiten kann die Brennkraftmaschine hinsichtlich Verbrauch und Leistung optimiert betrieben werden, was insbesondere aufgrund der hohen Energiepreise und Umweltanforderungen bei modernen Brennkraftmaschinen zwingend erforderlich ist. Der Nockenwellenversteller selbst weist einen Stator auf, der über den Riemen oder die Kette von der Kurbelwelle angetrieben wird, und einen Rotor, der drehfest mit der Nockenwelle verbunden ist. Zwischen dem Rotor und dem Stator sind Arbeitskammern vorgesehen, die wiederum durch an dem Rotor angeordnete Flügel in zwei gegensinnig wirkende Druckräume unterteilt werden.Phaser are in the professional world after a usual categorization in divided into two classes, camshaft adjuster with chain drive and belt-driven phaser. The camshaft adjuster gets over from a crankshaft driven by the belt or the chain and has the task of opening and closing times to adjust the gas exchange valves of an internal combustion engine. By the adjustment of the opening and closing times can the engine in terms of consumption and performance be operated optimally, which is particularly due to the high Energy prices and environmental requirements of modern internal combustion engines is mandatory. The camshaft adjuster itself has a Stator on, over the belt or chain is driven by the crankshaft, and a rotor rotatably connected to the camshaft. Between the rotor and the stator are provided working chambers, which in turn by arranged on the rotor wing in two opposing directions pressure chambers be divided.
Um den Drehwinkel des Rotors gegenüber dem Stator und damit der Nockenwelle gegenüber der Kurbelwelle zu verstellen, ist bei Nockenwellenverstellern mit Kettenantrieb z. B. ein Zentralventil vorgesehen, dass über einen in einer ortsfesten Struktur des Motors koaxial zu dem Zentralventil angeordneten Magneten angesteuert wird. Das Zentralventil umfasst einen feststehenden Hydraulikteil und einen in dem Hydraulikteil längs verschieblich geführten Kolben. In dem Hydraulikteil und dem Kolben sind jeweils Ölführungskanäle vorgesehen, die je nach Stellung des Kolbens miteinander verbunden sind. Die Ölführungskanäle in dem Hydraulikteil sind zusätzlich mit den Arbeitskammern verbunden und können je nach Stellung des Kolbens wahlweise mit Öldruck beaufschlagt werden, so dass der Öldruck in den Arbeitskammern in Abhängigkeit von der Stellung des Kolbens gesteuert werden kann. Durch die Veränderung der Drücke in den Arbeitskammern kann dann der Drehwinkel des Rotors gegenüber dem Stator und damit die Öffnungs- und Schließzeitpunkte der Gaswechselventile verändert werden. Während der Verstellung des Rotors wird jeweils ein Druckraum mit einem Ölstrom beaufschlagt, während das Öl aus dem Druckraum auf der anderen Seite des Flügels in einen Tank, der hier durch den Kettenkasten gebildet ist, abströmt.Around the angle of rotation of the rotor relative to the Stator and thus to adjust the camshaft against the crankshaft, is in z. B. with cam drive with chain drive z. B. provided a central valve, that over one in a stationary structure of the motor coaxial with the central valve arranged magnet is driven. The central valve includes a fixed hydraulic part and one in the hydraulic part longitudinally displaceable out Piston. In the hydraulic part and the piston each oil guide channels are provided, which are interconnected depending on the position of the piston. The oil guide channels in the Hydraulic part are additional connected to the working chambers and can depending on the position of the piston optionally with oil pressure be applied, so that the oil pressure in the working chambers dependent on can be controlled by the position of the piston. By the change the pressures in the working chambers then the angle of rotation of the rotor relative to the Stator and thus the opening and closing times changed the gas exchange valves become. While the adjustment of the rotor is in each case a pressure chamber subjected to an oil flow, while the oil from the pressure chamber on the other side of the wing into a tank, here formed by the chain case flows out.
Ein solches Abströmen des Ölstromes in den bei Riemenantrieben dem Kettenkasten entsprechen Riemenkasten ist nicht akzeptabel, da der Riemenantrieb grundsätzlich nicht im Öl laufen darf. Aus diesem Grund ist bei Nockenwellenverstellern mit Riemenantrieb die Verwendung eines Zentralventils bisher nicht möglich.One such outflow of the oil flow in the case of belt drives the chain case correspond to belt box is not acceptable because the belt drive is not to run in the oil may. For this reason, with belt driven camshaft adjusters the use of a central valve so far not possible.
Aufgabe ist es, einen Nockenwellenversteller mit einem Riemenantrieb zu schaffen, dessen Ölstrom über ein Zentralventil gesteuert wird.task is to use a camshaft adjuster with a belt drive too create its oil flow over one Central valve is controlled.
Die Aufgabe wird erfindungsgemäß durch einen Nockenwellenversteller mit den Merkmalen des Anspruchs 1 gelöst, während vorteilhafte Weiterbildungen den Unteransprüchen zu entnehmen sind.The Task is achieved by a camshaft adjuster having the features of claim 1, while advantageous Further developments of the dependent claims can be seen.
Erfindungsgemäß wird zur Lösung der Aufgabe vorgeschlagen, dass zur Steuerung des Öldruckes in den Druckräumen der Arbeitskammern ein Zentralventil mit einem längs verschieblich in dem Zentralventil geführten Kolben vorgesehen ist, der von einer Ansteuerseite des Nockenwellenverstellers von einem Aktuator mit einer Kraft beaufschlagbar ist, und der Nockenwellenversteller an seiner Ansteuerseite eine Dichtung aufweist, die den Austritt des Ölstromes in den den Riemenantrieb aufnehmenden Bauraum verhindert.According to the invention is for solution the task proposed that to control the oil pressure in the pressure chambers the working chambers a central valve with a longitudinally displaceable in the central valve out Piston is provided, which of a drive side of the camshaft adjuster of an actuator can be acted upon by a force, and the camshaft adjuster on its drive side has a seal which the outlet of the oil flow prevented in the belt drive receiving space.
Aufgrund der erfindungsgemäßen Lösung ist es ermöglicht, den Nockenwellenversteller mit Riemenantrieb über ein Zentralventil zu steuern, ohne dass das ablaufende Öl in den den Riemenantrieb aufnehmende Bauraum, auch Riemenkasten genannt, gelangen kann.by virtue of it is the solution according to the invention allows to control the camshaft adjuster with belt drive via a central valve, without the oil running off in the belt drive receiving space, also belt box called, can get.
Ferner wird vorgeschlagen, dass die Dichtung durch eine Balgdichtung gebildet ist, die mit ihrem radial äußeren Rand fest mit dem Nockenwellenversteller verbunden ist, und mittig mit einem dem Kolben zugeordneten Teil verbunden ist, an dem der Aktuator anliegt. Die Balgdichtung besitzt den Vorteil, dass sie den Nockenwellenversteller selbst insgesamt abdichtet, so dass an dieser Seite kein Öl mehr austreten kann, welche in den Bauraum des Riementriebes gelangen könnte. Außerdem besitzt die Balgdichtung den Vorteil, dass sie als statische Dichtung ausgeführt werden kann. Statische Dichtungen sind grundsätzlich unempfindlicher gegenüber Verschleiß und einfacher im Aufbau, so dass die Dichtwirkung über die Lebensdauer des abzudichtenden Bauteils besser ist und die Dichtung kostengünstiger ist. Ein weiterer Vorteil der Balgdichtung besteht darin, dass sie auch Axialbewegungen der Teile insbesondere des Kolbens ausführen kann, ohne dabei ihre Dichtwirkung zu verlieren.Further It is suggested that the seal is formed by a bellows seal is that with its radially outer edge firmly connected to the camshaft adjuster, and centered with a part associated with the piston is connected, at which the actuator is applied. The bellows seal has the advantage that it the camshaft adjuster self-sealing in total so that no more oil escapes from this side can, which could get into the space of the belt drive. Also owns the bellows seal the advantage that they are designed as a static seal can. Static seals are generally less sensitive to wear and easier In construction, so that the sealing effect over the life of the sealed Component is better and the seal is cheaper. Another advantage the bellows seal is that it also axial movements of the Parts in particular of the piston can run without losing their To lose sealing effect.
Es wird ferner vorgeschlagen, dass das mittig mit der Balgdichtung verbundene Teil und der Kolben einstückig ausgebildet sind. Dadurch wird die Stellbewegung des an dem Teil anliegenden Aktuators unmittelbar in eine Bewegung des Kolbens umgewandelt, was vorteilhaft für die Genauigkeit des Bewegungsablaufes der zusammenwirkenden Teile ist. Ferner ist dadurch die Teileanzahl reduziert, was wiederum günstig hinsichtlich der Fertigung, der Teilebevorratung und der Zuverlässigkeit im Dauerlaufbetrieb ist.It is further proposed that the part connected centrally with the bellows seal and the piston are formed integrally. Thereby, the adjusting movement of the voltage applied to the part actuator is directly converted into a movement of the piston, which is advantageous for the accuracy of Movement sequence of the cooperating parts. Further, this reduces the number of parts, which in turn is favorable in terms of manufacturing, parts storage and reliability in continuous operation.
Alternativ wird vorgeschlagen, dass das mittig mit der Balgdichtung verbundene Teil an der Stirnseite des Kolbens derart anliegt, dass ausschließlich Druckkräfte übertragbar sind. Dies kann z. B. sehr einfach dadurch erfolgen, indem das mittig mit der Balgdichtung verbundene Teil und der Kolben aus zwei getrennten Teilen gebildet sind. Hierdurch wird vermieden, dass unbeabsichtigte Druckschwankungen insbesondere Unterdrücke dazu führen können, dass die Balgdichtung den Kolben aus seiner Solllage zieht.alternative It is suggested that the center connected to the bellows seal Part on the front side of the piston is applied so that only compressive forces transferable are. This can be z. B. very easily done by the middle part connected to the bellows seal and the piston of two separate Parts are formed. This avoids unintentional Pressure fluctuations, in particular negative pressures can lead to the bellows seal pull the piston out of its nominal position.
Alternativ wird vorgeschlagen, dass eine Hülse vorgesehen ist, welche in einer koaxial zu dem Zentralventil angeordneten Bohrung einer Bauteilwand des den Riemenantrieb aufnehmenden Bauraumes und den aus dem Zentralventil austretenden Kolben umfasst und die Dichtung zwischen der Hülse und dem Nockenwellenversteller angeordnet ist. Da die Bauteilwand feststehend ausgebildet ist, und der Nockenwellenversteller sich dreht, muss entweder die Dichtung zwischen der Hülse und dem Nockenwellenversteller oder eine zweite Dichtung zwischen der Hülse und der Bauteilwand als dynamische Dichtung z. B. als Radialwellendichtring ausgeführt werden. Die Hülse besitzt den Vorteil, dass durch die Ausführung der Dichtung keine auf den Kolben wirkenden Axialkräfte entstehen können, die zu einem fehlerhaften Verstellen des Kolbens führen können.alternative It is suggested that a sleeve is provided, which arranged in a coaxial with the central valve Bore a component wall of the belt drive receiving space and the piston emerging from the central valve and the Seal between the sleeve and the camshaft adjuster is arranged. Because the component wall is fixed is formed, and the camshaft adjuster rotates must either the seal between the sleeve and the phaser or a second seal between the sleeve and the component wall as dynamic seal z. B. be performed as a radial shaft seal. The sleeve has the advantage that by the execution of the seal no on the axial forces acting on the piston can arise which can lead to a faulty adjustment of the piston.
Die Ölabfuhr kann in diesem Fall sehr einfach dadurch realisiert werden, indem die Hülse die Bauteilwand durchdringt und an ihrer von dem Nockenwellenversteller abgewandten Seite der Bauteilwand Bohrungen aufweist, durch die das aus den Druckräumen abgeführte Öl austritt.The oil removal can be realized in this case very simply by the sleeve the component wall penetrates and at its from the camshaft adjuster side facing away from the component wall has bores through which that from the pressure chambers discharged oil escapes.
Eine weitere bevorzugte Ausführungsform der Erfindung besteht darin, dass der Kolben hohl ausgebildet ist, und das aus den Druckräumen abgeführte Öl durch den Kolben zu einer außerhalb des den Riemenantrieb aufnehmenden Bauraumes angeordneten Ölablaufbohrung geführt ist.A Another preferred embodiment of Invention is that the piston is hollow, and that from the pressure chambers discharged oil the piston to an outside of the belt drive receiving space arranged oil drain hole guided is.
