Flügelzellenpumpen mit veränderlichem Verdrängungsvolumen zur Erzeugung eines Druckmittelstromes sind bekannt. Derartige Flügelzellenpumpen weisen einen vorzugsweise kreisförmigen Kurvenring auf, der um eine Lagereinrichtung abrollbar oder verschiebbar in einem Pumpengehäuse bzw. einem Außenring um den Kurvenring angeordnet ist. Ein Rotor mit radial verlaufenden Schlitzen, in denen Flügel verschieblich gehalten sind, greift in den Kurvenring ein und bildet eine Pumpenkammer mit einer Saug- und einer Drucköffnung.Vane pumps with changeable displacement for generating a pressure medium flow are known. Such vane pumps have a preferably circular Curved ring, which can be rolled or displaced around a bearing device in a pump housing or an outer ring is arranged around the cam ring. A rotor with radially extending Slits where wings slidably held, engages in the cam ring and forms a pump chamber with a suction and a pressure port.
Die
Die Stelleinrichtung wird im Wesentlichen durch eine erste Druckkammer und eine zweite Druckkammer zwischen der Außenseite des Kurvenrings und der Innenfläche des Pumpengehäuses oder der Innenfläche des Außenringes gebildet. Die erste und die zweite Druckkammer sind durch eine als Schwenklager ausgebildete Lagereinrichtung in Form eines axial verlaufenden Stiftes und durch ein in tangentialer Richtung der Außenseite des Kurvenringes beabstandet zu dem Schwenklager angeordnetes, axial verlaufendes Dichtmittel zwischen der Außenseite des Kurvenrings und der Innenfläche des Pumpengehäuses fluidisch voneinander getrennt. Der Druck in der ersten und zweiten Druckkammer wird von einer Regeleinrichtung, wie einer Steuerdrossel oder einem Kolbensteuerventil, die über Steuerkanäle mit den Druckkammern fluidisch verbunden ist und die Differenzdrücke in der ersten und zweiten Druckkammer in Abhängigkeit von dem aktuellen Verdrängungsvolumen oder Druck des Druckmittelstromes erzeugen, geregelt.The Actuator is essentially by a first pressure chamber and a second pressure chamber between the outside of the cam ring and the inner surface of the pump housing or the inner surface of the outer ring educated. The first and second pressure chambers are indicated by a Swivel bearing trained storage facility in the form of an axially extending Pin and through a tangential direction of the outside the cam ring spaced from the pivot bearing arranged, axially extending sealant between the outside of the cam ring and the inner surface of the pump housing fluidly separated from each other. The pressure in the first and second Pressure chamber is controlled by a control device, such as a control throttle or a piston control valve, which via control channels with the Pressure chambers is fluidically connected and the differential pressures in the first and second pressure chambers depending on the current displacement or generate pressure of the pressure medium flow, regulated.
Die Steuerkanäle in den bekannten Flügelzellenpumpen sind in der Regel durch mehrere Arbeitsschritte benötigende, spanabhebende Verfahren hergestellt und bedürfen eines gewissen Herstellungsaufwandes.The control channels in the known vane pumps are usually required by several steps, Machining produced and require a certain manufacturing effort.
Der Erfindung liegt die Aufgabe zugrunde, eine Flügelzellenpumpe kostengünstig mit reduziertem Bearbeitungsaufwand herzustellen.Of the Invention is the object of a vane pump cost with produce reduced processing costs.
Die Aufgabe wird mit einer Flügelzellenpumpe mit den Merkmalen des Anspruchs 1 gelöst.The Task is with a vane pump solved with the features of claim 1.
Dadurch dass die Steuerkanäle in der Art von Oberflächennuten unmittelbar beim Herstellungsvorgang der sie aufnehmenden Pumpengehäuseteile gebildet werden – durch formgebende Werkzeuge im Gieß- oder Sinterverfahren, oder durch spanabhebende Werkzeuge oder durch Umformung in die Oberfläche von Pumpengehäuseteilen – können aufwändige, zusätzlichen Bearbeitungsschritte bei der Herstellung der Steuerkanäle entfallen oder es vereinfachen sich die Bearbeitungsschritte beim Herstellen der Steuerkanäle. Als Pumpengehäuseteile gelten alle nicht im Betrieb der Flügelzellenpumpe bewegte Teile der Flügelzellenpumpe. Die Flügelzellenpumpe lässt sich mit reduziertem Kostenaufwand darstellen.Thereby that the control channels in the nature of surface grooves immediately during the manufacturing process of receiving pump housing parts be formed - by forming tools in the casting or sintering process, or by cutting tools or by Forming into the surface of pump housing parts - can be elaborate, additional Processing steps in the production of the control channels omitted or simplify the processing steps in manufacturing the control channels. As pump housing parts All parts not moving during operation of the vane pump are valid the vane pump. The vane pump let yourself at a reduced cost.

Ist die Flügelzellenpumpe mit einem, den Kurvenring radial umgebenden und bevorzugt aus einem Stahl- oder Sinterwerkstoff gebildeten Außenring versehen, so ist die Darstellung der Steuerkanäle, radial durch den Außenring oder in eine axiale Stirnfläche des Außenrings geführt, bei der Herstellung des Außenrings in einem Sinterverfahren oder Gießverfahren, wie etwa Kokillenguss, mit einem entsprechend geformten formgebenden Werkzeug möglich. Die Steuerkanäle lassen sich auch durch andere Verfahren, wie spanabhebende Verfahren oder durch Umformung als Oberflächennut einfacher darstellen, als beispielsweise als Bohrung oder dergleichen.is the vane pump with a radially surrounding the cam ring and preferably from a Provided steel or sintered material formed outer ring, so is the Representation of the control channels, radially through the outer ring or in an axial end face of the outer ring guided, in the manufacture of the outer ring in a sintering process or casting process, such as chill casting, possible with a correspondingly shaped shaping tool. The control channels can also by other methods, such as machining or by forming as a surface groove represent easier than, for example, as a bore or the like.
Es kann zweckmäßig sein, die Steuerkanäle in einer Stirnplatte des Pumpengehäuses anzuordnen. Die Steuerkanäle können beim Gießen der Stirnplatte, beispielsweise durch Kerne in dem formgebenden Werkzeug dargestellt werden. Die Steuerkanäle können in ihrem Querschnitt groß ausgebildet werden und beispielsweise durch Einsetzen von Einsetzteilen, wie Reduzierstücke, in ihrem Querschnitt verengt werden. Die Einsetzteile können dabei zusätzlich auch Dichtfunktion zwischen Pumpenteilen übernehmen.It may be appropriate the control channels in a face plate of the pump housing to arrange. The control channels can when casting the face plate, for example by cores in the shaping Tool are displayed. The control channels can be made large in their cross section and for example by inserting insertion parts, such as reducers, in narrowed their cross-section. The inserts can do this additionally also assume sealing function between pump parts.
Die Steuerkanäle lassen sich in axialer Richtung der Flügelzellenpumpe sowohl in der Nähe der Stirnplatte in die Druckkammer führen als auch in der Nähe oder an einem Pumpendeckel in die Druckkammer führen.The control channels can be in the axial direction of the vane pump both in the Near the front plate lead into the pressure chamber as well as nearby or lead to a pump cover in the pressure chamber.
Die Einsetzteile in den Steuerkanälen lassen sich als Kunststoffteile herstellen. Die Lage ihrer Mündungen an die jeweilige Druckkammer können in weitem Bereich in tangentialer Richtung des Kurvenrings gewählt werden.The Insert parts in the control channels can be produced as plastic parts. The location of their mouths to the respective pressure chamber be selected in a wide range in the tangential direction of the cam ring.
Die erfindungsgemäße Flügelzellenpumpe eignet sich bevorzugt für die Bereitstellung eines Druckmittelstromes für einen Verbraucher einer Hilfskraft- oder Fremdkraftlenkung eines Kraftfahrzeugs, wie etwa für einen Servozylinder, der von einem Lenkventil angesteuert ist oder für eine Niveauregulierung oder ein aktives Fahrwerk, etwa mit Wank-Regelung oder auch für ein Getriebe eines Kraftfahrzeugs.The vane pump according to the invention is preferably suitable for the provision of a pressure medium flow for a consumer of an auxiliary force or power steering of a motor vehicle, such as for a servo cylinder, which is controlled by a steering valve or for a level control or an active chassis, such as with roll control or for a transmission of a motor vehicle.
