Description
Die Erfindung betrifft eine Vorrichtung zur relativen Winkelverstellung zwischen zwei rotierenden, antriebsverbundenen Elementen gemäss dem Oberbegriff des Anspruches 1. The invention relates to a device for relative Angular adjustment between two rotating, drive-connected Elements according to the preamble of claim 1.
Vorrichtungen der eingangs genannten Art sind beispielsweise bei Brennkraftmaschinen bekannt und werden dort zur relativen Winkelverstellung der Nockenwelle gegenüber der diese antreibenden Kurbelwelle vorgesehen. Durch diesen Eingriff in die Ventiltriebskinematik werden die Phasenlage der Ventilöffnung, die Öffnungsdauer und der Ventilhub in Grenzen variabel beeinflusst. Devices of the type mentioned are, for example known in internal combustion engines and are there for relative Angular adjustment of the camshaft with respect to this driving crankshaft provided. Through this intervention in the Ventiltriebskinematik be the phase position of Valve opening, the opening duration and the valve lift within limits variable affected.
Aus der DE 100 36 275 A1 ist eine gattungsgemässe Vorrichtung zur relativen Winkelverstellung zwischen einer Nockenwelle und einer Kurbelwelle einer Brennkraftmaschine bekannt. Der Nockenwelle ist im Antrieb von der Kurbelwelle ein Kettenrad zugeordnet, das die Nockenwelle unter Vermittlung eines Übertragungsgliedes antreibt. Das Übertragungsglied erlaubt es eine Veränderung der relativen Winkelstellung der beiden rotierenden Elemente einzustellen. Diese Veränderung wird durch einen elektrischen Stellantrieb bewirkt, dessen Rotor eine Stellwelle des Übertragungsgliedes beaufschlagt und der in jedem Betriebszustand der Vorrichtung mitdreht. From DE 100 36 275 A1 is a generic device for relative angular adjustment between a camshaft and a crankshaft of an internal combustion engine known. Of the Camshaft is a sprocket in the drive of the crankshaft assigned to the camshaft through the intermediary of a Transmission element drives. The transmission link allows it a change in the relative angular position of the two to adjust rotating elements. This change is going through causes an electric actuator whose rotor a Actuating shaft of the transmission element acted upon and in rotates with each operating state of the device.
Bei durch Schwingungen ausgelösten Trägheitskräften auf den Rotor des Stellantriebes oder die Stellwelle des Übertragungsgliedes können unerwünschte Verstellungen der relativen Winkelstellung erfolgen. Dies muss vom Stellantrieb ausgeregelt werden und erfordert einen permanenten Energieeinsatz. Bei Ausfall des Stellantriebs ist diese Funktion nicht mehr möglich, es erfolgen unkontrollierte Verstellungen, die den Betrieb der Brennkraftmaschine erschweren und möglicherweise die Brennkraftmaschine beschädigen können. Da der Stellantrieb permanent mitlaufen muss, kann sich dieser auch im Normalbetrieb unzulässig erwärmen. In einem solchen Fall müsste die Brennkraftmaschine um eine Beschädigung des Stellantriebes zu vermeiden, stillgesetzt werden. When induced by vibrations inertial forces on the Rotor of the actuator or the control shaft of the Transfer member can be undesirable adjustments of the relative Angle position done. This must be done by the actuator be regulated and requires a permanent use of energy. If the actuator fails, this function is no longer available possible, there are uncontrolled adjustments that the Operation of the internal combustion engine complicate and possibly can damage the internal combustion engine. Since the Actuator must run permanently, this can also be in the Normal operation inadmissible heating. In such a case would have the internal combustion engine to damage the To avoid actuator to be shut down.
Zum allgemeinen technischen Hintergrund wird noch auf die DE 100 38 354 A1 und die DE 41 10 195 A1 verwiesen. For the general technical background is still on DE 100 38 354 A1 and DE 41 10 195 A1 referenced.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zu schaffen, bei welcher der Stellantrieb einen geringen elektrischen Energieverbrauch und die Vorrichtung einen sicheren Notlauf aufweist. The invention has for its object to provide a device create, in which the actuator has a low electrical energy consumption and the device a safe Has emergency running.
Diese Aufgabe wird erfindungsgemäss durch die im Kennzeichen des Patentanspruchs 1 gegebenen Merkmale gelöst. This object is achieved by the in the license plate of the claim 1 given characteristics solved.
Ein wesentlicher Vorteil der Erfindung besteht darin, dass im Normalbetrieb das Übertragungsglied bei unveränderter relativer Winkelstellung der beiden rotierenden Elemente blockiert werden kann und der Stellantrieb keine Energie benötigt. Dies führt zu einem insgesamt geringeren Energieverbrauch und damit zu einer geringeren Wärmebelastung des Stellantriebes. Sollte es dennoch zu einer unzulässigen Erwärmung des Stellantriebs kommen, kann dieser bei laufender Brennkraftmaschine zur Abkühlung stillgesetzt werden, ohne dass es zu einer unkontrollierten Verstellung der relativen Winkelstellung der beiden rotierenden Elemente führt. In einer besonderen Ausgestaltung der Erfindung, bei der im unbestromten Zustand des Stellantriebes, dessen Rotor mit mindestens einem der rotierenden Elemente wirkverbunden ist, erfolgt bei Ausfall des Stellantriebes eine automatische Blockierung des Übertragungsgliedes, somit ist ein problemloser Notlauf gewährleistet. An essential advantage of the invention is that in Normal operation the transmission element at unchanged relative angular position of the two rotating elements blocked can be and the actuator requires no energy. This leads to an overall lower energy consumption and thus to a lower heat load of the actuator. Should it nevertheless lead to an inadmissible warming of the Actuators come, this can while the internal combustion engine to be stopped for cooling without it becoming one uncontrolled adjustment of the relative angular position of two rotating elements leads. In a special Embodiment of the invention, wherein in the de-energized state of Actuator whose rotor with at least one of rotating elements is operatively connected, takes place in case of failure of Actuator automatic blocking of the Transfer link, so is a trouble-free emergency guaranteed.
Weitere Ausgestaltungen und Vorteile der Erfindung gehen aus den übrigen Unteransprüchen und der Beschreibung hervor. Further embodiments and advantages of the invention will be apparent the rest of the dependent claims and the description.
Nachstehend wird die Erfindung anhand einer schematisierten, teilweisen Schnittdarstellung erläutert, die einen Ausschnitt aus einem Nockenwellenantrieb einer Brennkraftmaschine mit einer erfindungsgemässen Vorrichtung zeigt. The invention will be described below with reference to a schematic, Partial sectional illustration explains a section from a camshaft drive an internal combustion engine with a device according to the invention.
In der teilweise im Schnitt gezeigten Schemadarstellung des Nockenwellenantriebes einer Brennkraftmaschine ist mit 1 ein rotierendes Element, das als Nockenwelle ausgebildet ist, bezeichnet. Dem rotierenden Element 1 ist im Antrieb von einer nicht dargestellten Kurbelwelle der Brennkraftmaschine ein weiteres rotierendes Element 2, welches als Kettenrad ausgeführt ist, zugeordnet. Das rotierende Element 2 treibt das rotierende Element 1 unter Vermittlung eines Übertragungsgliedes 3 an, so dass das rotierende Element 1 und das rotierende Element 2 die gleiche Drehzahl aufweisen. Das an seinem Umfang eine Kette tragende, rotierende Element 2 ist konzentrisch zum rotierenden Element 1 angeordnet und umschliesst dieses, wobei das Übertragungsglied 3 zwischen dem rotierenden Element 1 und dem rotierenden Element 2 liegt. Dieses nicht näher dargestellte Übertragungsglied 3 kann beispielsweise als Planetengetriebe, Taumelscheibengetriebe o. ä. ausgebildet sein und weist eine Stellwelle 4 auf, die von einem Rotor 5a eines elektrischen Stellantriebes 5 beaufschlagt wird. Das zum Verstellen erforderliche Antriebsmoment wird zwischen dem Rotor 5a und einem Stator 5b des Stellantriebes 5 erzeugt. In the schematic representation, partially shown in section, of the camshaft drive of an internal combustion engine, 1 denotes a rotating element, which is designed as a camshaft. The rotating element 1 is in the drive of a crankshaft, not shown, of the internal combustion engine, a further rotating element 2 , which is designed as a sprocket assigned. The rotating element 2 drives the rotating element 1 through the intermediary of a transmission member 3 , so that the rotating element 1 and the rotating element 2 have the same rotational speed. The bearing at its periphery a chain, rotating element 2 is arranged concentrically to the rotating element 1 and encloses this, wherein the transmission member 3 is located between the rotating element 1 and the rotating element 2 . This transfer member 3 , not shown in detail, for example, as a planetary gear, swash plate mechanism o. Ä. Be formed and has an actuating shaft 4 , which is acted upon by a rotor 5 a of an electric actuator 5 . The drive torque required for adjusting is generated between the rotor 5 a and a stator 5 b of the actuator 5 .
Durch eine Relativdrehung der Stellwelle 4 können die beiden rotierenden Elemente 1, 2 in ihrer relativen Winkelstellung zueinander verändert werden. Die Relativdrehung der Stellwelle 4 wird über den Rotor 5a des Stellantriebes 5 bewirkt. By a relative rotation of the control shaft 4 , the two rotating elements 1 , 2 are changed in their relative angular position to each other. The relative rotation of the control shaft 4 is effected via the rotor 5 a of the actuator 5 .
Um einen niedrigen Energieverbrauch und eine zuverlässige Notlauffunktion zu erreichen, ist die Stellwelle 4 erfindungsgemäss mit einem der rotierenden Elemente 1 oder 2 wirkverbindbar, wobei im Ausführungsbeispiel die Wirkverbindung zwischen Stellwelle 4 und rotierendem Element 2 dargestellt ist. Die Wirkverbindung der Stellwelle 4 mit dem rotierenden Element 2 erfolgt durch den Rotor 5a des Stellantriebes 5, der axial verschieblich mit der Stellwelle 4 verbunden ist. Durch die Wirkverbindung der Stellwelle 4 mit dem rotierenden Element 2 wird das Übertragungsglied 3 blockiert, wodurch die relative Winkelstellung der beiden rotierenden Elemente 1 und 2 konstant bleibt. In order to achieve low energy consumption and reliable emergency operation, the control shaft 4 is according to the invention with one of the rotating elements 1 or 2 operatively connected, wherein in the embodiment, the operative connection between the adjusting shaft 4 and rotating element 2 is shown. The operative connection of the control shaft 4 with the rotating element 2 is effected by the rotor 5 a of the actuator 5 , which is axially displaceably connected to the control shaft 4 . By the operative connection of the control shaft 4 with the rotating element 2 , the transmission member 3 is blocked, whereby the relative angular position of the two rotating elements 1 and 2 remains constant.
Bei unbestromtem Stellantrieb ist der Rotor 5a mit dem rotierenden Element 2 wirkverbunden. Die Wirkverbindung zwischen Rotor 5a und rotierendem Element 2 erfolgt durch eine Axialkraftbeaufschlagung FA1 des Rotors 5a, wobei die Beaufschlagung mittels einer Tellerfeder 6 erzeugt wird. Zur Erzeugung dieser Axialkraft FA1 können auch andere Wirkprinzipien herangezogen werden. When energized actuator, the rotor 5 a with the rotating element 2 is operatively connected. The operative connection between the rotor 5 a and a rotating element 2 takes place by an axial force F A1 of the rotor 5 a, wherein the application is generated by means of a plate spring 6 . To generate this axial force F A1 , other principles of action can also be used.
Bei bestromtem Stellantrieb ist die Wirkverbindung zwischen Rotor 5a und rotierendem Element 2 gelöst um die elektrische Antriebsleistung des Stellantriebs 5 gering zu halten. Vorteilhafterweise ist bei bestromtem Stellantrieb 5 eine Axialkraftkomponente FA2 zwischen Stator 5b und Rotor 5a des Stellantriebes 5 wirksam. Dies kann beispielsweise durch einen Axialversatz 7 zwischen Stator 5b und Rotor 5a erfolgen, da durch diesen Versatz 7 die Magnetkraftwirkung zwischen Rotor 5a und Stator 5b diese Axialkraftkomponente FA2 hervorruft. When energized actuator the operative connection between the rotor 5 a and rotating element 2 is released to keep the electric drive power of the actuator 5 low. Advantageously, when the actuator 5 is energized, an axial force component F A2 between the stator 5 b and the rotor 5 a of the actuator 5 is effective. This can be done, for example, by an axial displacement 7 between the stator 5 b and rotor 5 a, as caused by this offset 7, the magnetic force action between the rotor 5 a and 5 b stator this axial force component F A2 .
Um den Rotor 5a nicht gehäusefest zu lagern und dadurch Reibungsverluste zu erzeugen, ist der Rotor 5a auf dem rotierenden Element 1 gelagert, wobei auch eine Lagerung auf einem anderen rotierenden Element, wie beispielsweise der Stellwelle 4, denkbar ist. In order not to store the rotor 5 a fixed to the housing and thereby generate friction losses, the rotor 5 a is mounted on the rotating element 1 , wherein a bearing on another rotating element, such as the control shaft 4 , is conceivable.
Die Wirkverbindung zwischen der Stellwelle 4 und einem der rotierenden Elemente 1, 2 kann auch durch ein hier nicht dargestelltes, separat anzusteuerndes Bauteil erfolgen. Das Bauteil kann als reibschlüssiges Verbindungselement, wie beispielsweise eine Bremse, und/oder als formschlüssiges Verbindungselement, wie beispielsweise eine Kupplung, und/oder ein kraftschlüssiges Verbindungselement, wie beispielsweise eine Magnetkupplung, ausgebildet sein. The operative connection between the control shaft 4 and one of the rotating elements 1 , 2 can also be done by a not shown here, to be controlled separately component. The component may be formed as a frictional connection element, such as a brake, and / or as a positive connection element, such as a clutch, and / or a frictional connection element, such as a magnetic coupling.
Jede der oben beschrieben Wirkverbindungsmöglichkeiten kann vorteilhafterweise reibschlüssig erfolgen. Each of the above-described Wirkverbindungsmöglichkeiten can advantageously done by friction.
