Description
Die vorliegende Erfindung betrifft eine Pendelschieberpumpe, insbesondere zur Versorgung eines Verbrennungsmotors mit Schmierstoff, beispielsweise mit Öl, gemäß dem Oberbegriff des Anspruchs 1. The present invention relates to a pendulum slide pump, in particular for supplying an internal combustion engine with lubricant, for example with oil, according to the preamble of
Der Einsatz von mengengeregelten Pendelschieberpumpen bei Verbrennungsmotoren ist seit langem Stand der Technik, um beispielsweise eine Fördermenge und einen Druck an den Bedarf des Verbrennungsmotors leicht anpassen zu können. Eine derartige Anpassung erfolgt meist über das Beaufschlagen eines Schiebers innerhalb der Pendelschieberpumpe mit einem aus einer Hauptölgalerie des Verbrennungsmotors stammenden Öldruck.The use of volume-controlled pendulum slide pumps in internal combustion engines has long been state of the art, for example, to easily adjust a flow rate and pressure to the needs of the internal combustion engine can. Such adaptation usually takes place via the application of a slide within the pendulum slide pump with a oil pressure originating from a main oil gallery of the internal combustion engine.

Die vorliegende Erfindung beschäftigt sich mit dem Problem, für eine Pendelschieberpumpe der gattungsgemäßen Art eine verbesserte oder zumindest eine alternative Ausführungsform anzugeben, die sich insbesondere durch eine gesteigerte Funktionalität auszeichnet.The present invention addresses the problem of providing an improved or at least one alternative embodiment for a pendulum slider pump of the generic type, which is characterized in particular by an increased functionality.
Dieses Problem wird erfindungsgemäß durch den Gegenstand des unabhängigen Anspruchs 1 gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This problem is solved according to the invention by the subject matter of
Die vorliegende Erfindung beruht auf dem allgemeinen Gedanken, das an sich bekannte Arbeitsprinzip einer Pendelschieberpumpe beizubehalten, gleichzeitig aber die Lagerung der einzelnen Pendel umzukehren, indem bei einer erfindungsgemäßen Pendelschieberpumpe die Pendel nicht mehr gelenkig am Außenrotor sondern vielmehr gelenkig am Innenrotor gelagert und radial im Außenrotor in zugehörigen Pendelführungen geführt sind. Zusätzlich ist die Pendelschieberpumpe in der Lage, zwei unterschiedliche Förderdrücke bereitzustellen. Die beiden Förderdrücke können jeweils anderen, also unterschiedlichen Kreisläufen zu geordnet werden. Die zugehörigen Medien können jedoch nicht von unterschiedlicher Art sein, da eine geringe Austauschrate nicht vermeidbar ist. Dabei bilden die Pendelschieber, der Innenrotor und der Außenrotor Kammern einer ersten Druckstufe und die Pendel und der Außenrotor Kammern einer zweiten Druckstufe der Pendelschieberpumpe bilden. Die erste Druckstufe kann dabei als Niederdruckstufe ausgebildet sein, wogegen die zweite Druckstufe als Hochdruckstufe dienen kann. Mit der Bereitstellung bzw. Erzeugung von zumindest zwei unterschiedlichen Druckniveaus können unterschiedliche Anwendungen mit ein und derselben Pendelschieberpumpe bedient werden, so kann beispielsweise das komprimierte Pumpmedium in der Hochdruckstufe zur Schaltung eines Getriebes verwendet werden, wogegen die Niederdruckstufe lediglich zur Kühlung/Schmierung verwendet wird. Generell kann hierdurch die Funktionalität der Pendelschieberpumpe gesteigert werden, da diese gleichzeitig unterschiedliche Förderdrücke bereitstellen kann. The present invention is based on the general idea to maintain the per se known working principle of a pendulum slide pump, but at the same time reverse the storage of individual pendulum by the pendulum no longer articulated on the outer rotor but rather hinged to the inner rotor and radially in the outer rotor in a pendulum slide pump according to the invention associated pendulum guides are guided. In addition, the shuttle pump is able to provide two different delivery pressures. The two delivery pressures can each be assigned to different, ie different circuits. However, the associated media can not be of different types, since a low exchange rate is unavoidable. The pendulum slides, the inner rotor and the outer rotor form chambers of a first pressure stage and the pendulum and the outer rotor form chambers of a second pressure stage of the pendulum slide pump. The first pressure stage can be designed as a low-pressure stage, whereas the second pressure stage can serve as a high-pressure stage. With the provision or generation of at least two different pressure levels different applications can be operated with one and the same shuttle pump, so for example the compressed pumping medium can be used in the high-pressure stage for switching a transmission, whereas the low-pressure stage is used only for cooling / lubrication. In general, this can increase the functionality of the pendulum vane pump since it can simultaneously provide different delivery pressures.
Die Pendelschieberpumpe kann durch einen externen Motor, einen Elektromotor oder einen Verbrennungsmotor angetrieben werden. Die Übertragung der Kraft und der Drehzahl erfolgt entweder über eine Welle, die den Innenrotor antreibt oder über den Außenrotor, der von außen angetrieben wird.The pendulum vane pump can be powered by an external motor, an electric motor or an internal combustion engine. The transmission of power and speed is either via a shaft that drives the inner rotor or the outer rotor, which is driven from the outside.
Die Herstellungsverfahren für die jeweiligen Bestandteile der Pendelschieberpumpe wie Innenrotor, Außenrotor, Pendel und weitere können sowohl Sintern, Gießen, Stanzen oder andere sein. Die zu wählenden Herstellungsverfahren hängen von den geplanten Ausgestaltungen der Pendelschieberpumpe ab. Auch die Materialien können je nach Anforderung an die Pendelschieberpumpe verschiedene Metalle oder Legierungen wie auch Kunststoffe sein.The manufacturing processes for the respective components of the pendulum slide pump such as inner rotor, outer rotor, pendulum and others can be both sintering, casting, stamping or others. The manufacturing processes to be chosen depend on the planned designs of the pendulum vane pump. Depending on the requirements of the pendulum vane pump, the materials can also be different metals or alloys as well as plastics.
Bei einer vorteilhaften Weiterbildung der Erfindung, soll die Pendelschieberpumpe nicht mehr von außen mechanisch, beispielsweise mittels eines Riemen- oder Kettentriebs angetrieben werden, sondern Teil eines Elektromotors selbst sein. Der Antrieb erfolgt elektromotorisch über den Außenrotor. Hierzu sind im Außenrotor in entsprechenden Ausnehmungen Magnete, insbesondere Permanentmagnete, angeordnet sind, wogegen außerhalb des Außenrotors ein Stator mit Elektromagneten angeordnet ist. Die Magnete und die Elektromagnete bilden dabei die Bestandteile des elektromotorischen Antriebs zum Antrieb der Pendelschieberpumpe. Der Außenrotor kann beispielsweise als kostengünstiges Blechformteil ausgebildet werden, in welchem zugleich die Ausnehmungen zur Aufnahme der Magnete mit eingeformt werden. Hierdurch ist ein kompakt bauender, kostengünstiger und von einer externen Kraftquelle unabhängiger Antrieb der Pendelschieberpumpe möglich. In an advantageous embodiment of the invention, the pendulum slide pump is no longer mechanically driven from the outside, for example by means of a belt or chain drive, but be part of an electric motor itself. The drive is carried out by an electric motor via the outer rotor. For this purpose, magnets, in particular permanent magnets, are arranged in the outer rotor in corresponding recesses, whereas outside the outer rotor a stator with electromagnets is arranged. The magnets and the electromagnets form the components of the electromotive drive for driving the pendulum slide pump. The outer rotor can be formed for example as a cost-effective sheet metal part, in which at the same time the recesses for receiving the magnets are formed with. As a result, a compact, cost-effective and independent of an external power source drive the pendulum slide pump is possible.
Die erfindungsgemäße Pendelschieberpumpe dient beispielsweise zur Versorgung eines Verbrennungsmotors mit Schmierstoff, insbesondere zur Versorgung mit Öl. Sie kann alternativ auch zum Fördern anderer flüssiger Medien eingesetzt werden, wie zum Beispiel Wasser, Kühlmittel oder ähnliches. Ihre Verwendung ist nicht auf Kraftfahrzeuge oder Verbrennungsmotoren beschränkt. Sie kann in mobilen wie stationären Bereichen eingesetzt werden. The pendulum slide pump according to the invention serves, for example, to supply an internal combustion engine with lubricant, in particular for supplying oil. Alternatively, it can also be used to convey other liquid media, such as water, coolant or the like. Their use is not limited to motor vehicles or internal combustion engines. It can be used in mobile as well as stationary areas.
Die erfindungsgemäße Pendelschieberpumpe weist einen drehbar, bzw. rotierend gelagerten Innenrotor auf, der über besagte Pendel mit dem Außenrotor in Verbindung steht. Im Unterschied zu bisher aus dem Stand der Technik bekannten Pendelschieberpumpen, bei welchen die Pendel gelenkig am Außenrotor gelagert und radial im Innenrotor geführt waren, kann bei der erfindungsgemäßen Pendelschieberpumpe der Innenrotor deutlich kleiner ausgebildet werden und dadurch deutlich kompakter bauen, wodurch ein nicht zu unterschätzender Packagevorteil entsteht. Das Wirkprinzip der erfindungsgemäßen Pendelschieberpumpe unterscheidet sich dabei nicht von dem bisher bekannter Pendelschieberpumpen. Die großen Vorteile der erfindungsgemäßen Pendelschieberpumpe liegen insbesondere im Entfall des hohen Material- und Bauraumbedarfs am Innenrotor sowie einer Verringerung der Komplexität des Außenrotors, da eine Pendelkopf-Umschlingung von mehr als 180° nunmehr am Innenrotor angeordnet wird. Durch die gänzlich andere Ausgestaltung des Außenrotors ist es zusätzlich möglich, diesen aus gänzlich anderen Materialien und auch durch andere Fertigungsverfahren herzustellen, beispielsweise kann hierfür ein einfaches Blechformteil mit entsprechenden Aussparungen für Magnete verwendet werden. Der Innenrotor hingegen kann beispielsweise als Sinterteil erhalten bleiben. The pendulum slide pump according to the invention has a rotatably mounted or rotatably mounted inner rotor, which is connected via said pendulum to the outer rotor. In contrast to previously known from the prior art pendulum slide pumps, in which the pendulum articulated mounted on the outer rotor and guided radially in the inner rotor, the inner rotor can be made significantly smaller in the pendulum slide pump according to the invention and thereby build significantly compact, creating a not inconsiderable package advantage arises. The operating principle of the pendulum slide pump according to the invention does not differ from the previously known pendulum slide pumps. The great advantages of the pendulum slide pump according to the invention are in particular the elimination of the high material and space requirements on the inner rotor and a reduction in the complexity of the outer rotor, since a pendulum head wrap of more than 180 ° is now arranged on the inner rotor. Due to the completely different embodiment of the outer rotor, it is also possible to produce these completely different materials and also by other manufacturing processes, for example, this can be a simple sheet metal part are used with corresponding recesses for magnets. The inner rotor, however, can be preserved, for example, as a sintered part.
