Description
Die vorliegende Erfindung betrifft eine Flügelzellenpumpe gemäß der im Oberbegriff des Patentanspruches 1 näher definierten Art. The present invention relates to a vane pump according to the closer defined in the preamble of
Beispielsweise sind mechanische Flügelzellenpumpen mit verstellbarem Hubring hinreichend bekannt. Bei derartigen Flügelzellenpumpen ist eine Hinterflügelraum-Druckbeaufschlagung vorgesehen, um im laufenden Betrieb die jeweiligen Flüge derart mit Hinterflügelraumdruck zu beaufschlagen, so dass diese radial nach außen bewegt werden. Jedoch beim Start der Flügelzellenpumpe muss zunächst der Pumpendruck aufgebaut werden, so dass zunächst kein Hinterflügelraumdruck vorliegt. Zudem ergibt sich bei Tiefenumgebungstemperaturen das Problem, dass die Flügel aufgrund der Reibungsverhältnisse im Fügespalt nicht selbständig ausfahren und somit kein Pumpendruck erzeugt werden kann. For example, mechanical vane pumps with adjustable cam ring are well known. In such vane pumps, a Hinterflügelraum-pressurization is provided to apply during operation of the respective flights so with Hinterflügelraumdruck so that they are moved radially outward. However, at the start of the vane pump, the pump pressure must first be established so that there is initially no rear wing space pressure. In addition, the problem arises at depth ambient temperatures that the vanes do not autonomously extend due to the friction conditions in the joint gap and thus no pump pressure can be generated.
Deshalb sind bei Flügelzellenpumpen so genannte Zwangsführungen vorgesehen. Beispielsweise kann hierzu ein Zwangsführungsring radial innen an dem Rotor vorgesehen sein, sodass dieses zusätzliche Bauteil die Flügel mechanisch zwangsführt. Jedoch ergibt sich aufgrund der radialen Abmessungen des Zwangsführungsringes ein zusätzlicher radialer Bauraumbedarf, da der Zwangsführungsring radial innen eingelegt ist. Um die gleichen Dichtverhältnisse, wie bei einer Flügelzellenpumpe ohne Zwangsführungsring, zu erhalten, ist somit ein radial gesehen größerer Bauraum erforderlich. Ansonsten ergibt sich ein schlechterer hydraulischer Wirkungsgrad. Therefore, so-called forced guides are provided with vane pumps. For example, for this purpose, a positive guide ring can be provided radially inward on the rotor, so that this additional component mechanically forces the blades. However, due to the radial dimensions of the positive guide ring results in an additional radial space requirement, since the positive guide ring is inserted radially inward. In order to obtain the same sealing conditions as in a vane pump without positive guide ring, thus a radially larger space is required. Otherwise results in a poorer hydraulic efficiency.
Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, eine Flügelzellenpumpe der eingangs beschriebenen Gattung vorzuschlagen, bei der ohne Wirkungsgradverluste und ohne zusätzlichen Bauraumbedarf eine Zwangsführung gewährleistet wird. The present invention is based on the object to propose a vane pump of the type described above, in which a forced operation is ensured without loss of efficiency and no additional space requirement.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruches 1 gelöst. Zusätzliche Vorteile und vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen und der Beschreibung sowie den Zeichnungen. This object is achieved by the features of
Somit wird eine Flügelzellenpumpe mit einem in einem verstellbaren Hubring drehbar gelagerten und von einer Antriebswelle angetriebenen Rotor mit mehreren Flügeln vorgeschlagen, die in radial verlaufenden Schlitzen des Rotors radial verschiebbar gelagert sind. Die Flügel sind mit Hinterflügelraumdruck beaufschlagbar, wobei zumindest einem Flügel ein Zwangsführungselement zum radialen Bewegen des Flügels derart zugeordnet ist, dass das Zwangsführungselement in den Rotor und/oder in die Antriebswelle bauraumneutral integriert wird. Thus, a vane pump with a rotatably mounted in an adjustable cam ring and driven by a drive shaft rotor is proposed with a plurality of wings, which are mounted radially displaceable in radially extending slots of the rotor. The wings are acted upon Hinterflügelraumdruck, wherein at least one wing a positive guide element for radially moving the wing is assigned such that the positive guide element is integrated space-neutral in the rotor and / or in the drive shaft.
Auf diese Weise wird der vorhandene Bauraum des Rotors und der Antriebswelle genutzt, um das Zwangsführungselement bauraumneutral unterzubringen. Die Integration bedeutet, dass das Zwangsführungselement zumindest abschnittsweise die Antriebswelle und/oder den Rotor radial durchläuft. In this way, the existing space of the rotor and the drive shaft is used to accommodate the positive guide element space neutral. The integration means that the positive guide element at least partially passes through the drive shaft and / or the rotor radially.
Somit wird jederzeit das Ansaugverhalten bei der erfindungsgemäßen Flügelzellenpumpe sichergestellt und somit Wirkungsgradverluste und auch Bauraumerweiterungen in vorteilhafter Weise verhindert. Thus, at any time the intake behavior is ensured in the vane pump according to the invention and thus efficiency losses and also space expansions prevented in an advantageous manner.
Gemäß einer möglichen Ausführungsvariante der vorliegenden Erfindung kann vorgesehen sein, dass zwei Flügel über das die Antriebswelle radial durchlaufende und in dem Rotor abschnittsweise verlaufende Zwangsführungselement miteinander gekoppelt sind. Als Zwangsführungselement kann eine starre oder auch eine nicht starre Koppelstange vorgesehen sein. According to a possible embodiment of the present invention can be provided that two wings are coupled to each other via the drive shaft radially passing and in the rotor sections running positive guide element. As a positive guide element may be provided a rigid or a non-rigid coupling rod.
Bei der Verwendung einer konstruktiv einfach aufgebauten starren Koppelstange sind die zwangsgeführten Flügel gegenüberliegend angeordnet. Dadurch wird sichergestellt, dass, wenn der eine Flügel eingefahren ist, der andere radial nach außen geführt wird, um einen entsprechenden Pumpendruck sofort beim Starten der Pumpe aufbauen zu können. Damit wird generell das Startverhalten bei der erfindungsgemäßen Flügelzellenpumpe optimiert, ohne dass eine erhöhte Leckage aufgrund der reduzierten Länge des Axialspaltes auftritt. When using a structurally simple design rigid coupling rod, the positively driven wing are arranged opposite one another. This ensures that, when one wing is retracted, the other is guided radially outward to build up a corresponding pump pressure immediately upon starting the pump. This generally optimizes the starting behavior in the vane-cell pump according to the invention without an increased leakage occurring due to the reduced length of the axial gap.
Nicht starre Koppelstangen, wie zum Beispiel gelenkige Koppelstange oder dergleichen können bei nicht gegenüberliegenden Flügeln zur Zwangsführung eingesetzt werden. Die gelenkige Koppelstange umfasst beispielsweise ein erstes Stangenelement und ein zweites Stangenelement, welche gelenkig miteinander in Wirkverbindung stehen. Als gelenkige Verbindung kann zum Beispiel ein Gleitstein, aber auch andere konstruktive Lösungen vorgesehen sein. Auf diese Weise sind auch Zwangsführungen bei Flügelzellenpumpe mit asymmetrischen Flügelanordnungen ohne weiteres möglich. Non-rigid coupling rods, such as articulated coupling rod or the like can be used in non-opposing wings for positive guidance. The articulated coupling rod comprises, for example, a first rod element and a second rod element, which are articulated to each other in operative connection. As an articulated connection, for example, a sliding block, but also other constructive solutions can be provided. In this way, forced guides in vane pump with asymmetrical wing arrangements are readily possible.
Gemäß einer weiteren Ausführungsvariante ist es auch denkbar, dass lediglich ein Flügel zwangsgeführt ist. Diese Ausführung bietet sich besonders bei doppelhubigen Flügelzellpumpen an. According to a further embodiment, it is also conceivable that only one wing is forcibly guided. This version is particularly suitable for double-stroke vane-cell pumps.
Beispielsweise kann dazu als Zwangsführungselement ein in einer radial durch die Antriebswelle durchlaufende Führungsausnehmung angeordnetes federbelastetes Kolbenelement vorgesehen sein, welches mit einer rotorseitig angeordneten Koppelstange zum Zwangsbetätigen des zugeordneten Flügels in Wirkverbindung steht. Bei dieser möglichen Ausführung ist das Zwangsführungselement quasi in die Antriebswelle und zum Teil in den Rotor integriert. For example, can be provided as a positive guide element in a radially passing through the drive shaft guide recess arranged spring-loaded piston element, which is in operative connection with a rotor side coupling rod arranged for Zwangssbetätigen the associated blade. At this Possible embodiment, the positive guide element is quasi integrated into the drive shaft and partly in the rotor.
Eine andere Art der Ausführung kann vorsehen, dass als Zwangsführungselement ein federbelastetes in dem radial verlaufenden Schlitz des zugeordneten Flügels des Rotors geführtes Kolbenelement vorgesehen ist, welches auf der dem Federelement abgewandten Seite mit dem Flügel in Wirkverbindung steht. Bei dieser Ausführung ist das Zwangsführungselement nur in den Rotor integriert. Another type of embodiment may provide that a spring-loaded guided in the radially extending slot of the associated blade of the rotor piston member is provided as a forced guide element, which is on the side facing away from the spring element with the wing in operative connection. In this embodiment, the positive guide element is integrated only in the rotor.
