Description
Die Erfindung betrifft eine Flügelzellenpumpe nach dem Oberbegriff des Patentanspruches 1. The invention relates to a vane pump according to the preamble of claim 1.
Flügelzellenpumpen sind bekannt, und zwar in einhubiger und doppelhubiger Bauweise. Ein Problem bei Flügelzellenpumpen besteht darin, dass die Flügel nach dem Abstellen der Pumpe „einfallen“ und die Pumpe beim Wiederanlauf nicht sofort den vollen Volumenstrom fördert. Bei Flügelzellenpumpen in einhubiger und doppelhubiger (zweiflutiger) Bauweise wurde dieses Problem bereits auf verschiedene Weise gelöst:

Der Erfindung liegt das Problem zu Grunde, das Hochfahren einer Flügelzellenpumpe der eingangs genannten Art zu beschleunigen, insbesondere ein Einfallen der Flügel zu verhindern, um somit beim Anfahren der Flügelzellenpumpe möglichst schnell die volle Leistung der Pumpe zu erreichen. Derartige Anfahrschwierigkeiten treten insbesondere bei niedrigen Außentemperaturen respektive bei zähflüssigem Öl, welches von der Flügelzellenpumpe gefördert wird, auf. The invention is based on the problem to accelerate the startup of a vane pump of the type mentioned above, in particular to prevent a collapse of the wings, so as quickly as possible to achieve the full power of the pump when starting the vane pump. Such Anfahrschwierigkeiten occur in particular at low outdoor temperatures respectively in viscous oil, which is funded by the vane pump on.
Das der Erfindung zu Grunde liegende Problem wird durch die Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen. The problem underlying the invention is solved by the features of claim 1. Advantageous embodiments emerge from the subclaims.
Erfindungsgemäß sind bei einer Flügelzellenpumpe einerseits am Flügel und andererseits am Gehäuse, bevorzugt an einem oder beiden Deckeln miteinander korrespondierende, formschlüssige Mittel vorgesehen, die einen Zwanglauf der Flügel bewirken. Zwanglauf bedeutet hier, dass die Flügel bei umlaufendem Rotor auf eine Bahn gezwungen werden, bei der sich die Flügelspitzen bzw. die Flügelaußenkanten in ständiger Anlage zur Hubkontur befinden. Formschlüssige Mittel sind beispielsweise ein Zapfen und eine umlaufende Nut, wobei der Zapfen in die Nut eingreift und in der Nut auf einer Bahn geführt wird, welche der Hubkontur geometrisch ähnlich ist. Somit kann beim Anfahren der Flügelzellenpumpe sofort der volle Volumenstrom gefördert werden. According to the invention, with a vane pump on the one hand on the wing and on the other hand on the housing, preferably on one or both covers mutually corresponding, positive locking means are provided which cause a forced running of the wings. Forced running here means that the blades are forced with rotating rotor on a path in which the wing tips or the wing outer edges are in constant contact with the stroke contour. Positive locking means are, for example, a pin and a circumferential groove, wherein the pin engages in the groove and is guided in the groove on a path which is geometrically similar to the Hubkontur. Thus, the full volume flow can be promoted immediately when starting the vane pump.
Nach einer bevorzugten Ausführungsform sind die formschlüssigen Mittel einerseits als Flügelinnenkante und andererseits als gehäuseseitiger Absatz ausgebildet. Dabei ist an mindestens einem der Deckel ein nach innen ragender Absatz mit einer Außenkontur angeordnet, auf welcher sich die Innenkanten der Flügel abstützen. Die Außenkontur des Absatzes entspricht der Innen- oder Hubkontur des Hubringes, d. h. die Außenkontur des Absatzes ist geometrisch ähnlich der Hubkontur des Hubringes. Zwischen der Außenkontur und der Innenkontur sind die Flügel radial beweglich angeordnet, wobei die Flügel zwangsgeführt sind, d. h. einem Zwanglauf unterliegen. Ein Einfallen der Flügel wird somit wirksam verhindert, und die Flügelspitzen (Außenkanten) befinden sich in ständigem Kontakt mit der Hubkontur. According to a preferred embodiment, the form-fitting means are formed on the one hand as a wing inner edge and on the other hand as a housing-side paragraph. In this case, an inwardly projecting shoulder with an outer contour is arranged on at least one of the lid, on which the inner edges of the wings are supported. The outer contour of the shoulder corresponds to the inner or stroke contour of the lifting ring, d. H. the outer contour of the shoulder is geometrically similar to the stroke contour of the lifting ring. Between the outer contour and the inner contour, the wings are arranged radially movable, wherein the wings are positively guided, d. H. subject to a forced run. A collapse of the wings is thus effectively prevented, and the wing tips (outer edges) are in constant contact with the stroke contour.
Nach einer weiteren bevorzugten Ausführungsform ist die Flügelzellenpumpe in doppelhubiger bzw. zweiflutiger Bauweise ausgeführt, d. h. die Hubkontur bzw. die Innenkontur des Hubringes ist annährend oval ausgebildet. Bei einer vollen Umdrehung des Rotors wird das Druckmedium somit zweimal angesaugt und zweimal ausgestoßen. Die doppelhubige Bauweise wird vorteilhaft bei Getriebeölpumpen für Automatikgetriebe in Kraftfahrzeugen eingesetzt, wobei der Rotor der Flügelzellenpumpe durch den Verbrennungsmotor des Kraftfahrzeuges angetrieben wird. Ein spezielles Problem beim Antrieb der Flügelzellenpumpe durch einen Verbrennungsmotor besteht darin, dass dieser beim Starten zunächst rückwärts drehen kann und damit die Pumpe in entgegengesetzter Richtung läuft, wodurch die Flügel nach innen gedrückt und dadurch erhöhte Anlaufschwierigkeiten auftreten würden. Dieses spezielle Problem wird durch den erfindungsgemäßen Zwanglauf der Flügel behoben. Bei einem etwaigen Rückwärtsdrehen der Antriebsmaschine können die Flügel nicht nach innen gedrückt werden oder einfallen. According to a further preferred embodiment, the vane pump is designed in double-stroke or double-flow design, ie, the stroke contour or the inner contour of the cam ring is formed approximately oval. In one full revolution of the rotor, the pressure medium is thus sucked twice and ejected twice. The double-stroke design is advantageously used in gear oil pumps for automatic transmission in motor vehicles, wherein the rotor of the vane pump is driven by the internal combustion engine of the motor vehicle. A special problem with driving the vane pump by an internal combustion engine is that it can initially turn backwards when starting and thus the pump runs in the opposite direction, whereby the wings would be pressed inwards and thus increased start-up difficulties would occur. This particular problem is solved by the inventive forced running of the wings. In a possible reverse rotation of the prime mover, the Wings do not press inward or invade.
Nach einer weiteren bevorzugten Ausführungsform ragen die Flügel zumindest nach einer Seite über die Stirnfläche des Rotors hinaus, d. h. sie bilden einen Überstand und können sich an dem nach innen ragenden Absatz abstützen. Damit ergibt sich eine einfache konstruktive Lösung, um einen Zwanglauf der Flügel zu erreichen, wobei sich die Flügelspitzen in ständigem Kontakt mit der Hubkontur befinden. Besonders vorteilhaft ist es, wenn an beiden Deckeln nach innen ragende Absätze angeordnet sind, so dass die über die Stirnflächen hinaus stehenden Flügel symmetrisch auf beiden Seiten abgestützt werden. Dadurch kann ein etwaiges Verkippen der Flügel vermieden werden. Der Überstand der Flügel entspricht etwa der Tiefe des Absatzes am Deckel. According to a further preferred embodiment, the wings protrude beyond the end face of the rotor at least to one side, d. H. they form a supernatant and can be supported on the inwardly projecting heel. This results in a simple constructive solution to achieve a forced operation of the wings, wherein the wing tips are in constant contact with the stroke contour. It is particularly advantageous if inwardly projecting shoulders are arranged on both lids, so that the wings projecting beyond the end faces are supported symmetrically on both sides. As a result, any tilting of the wings can be avoided. The projection of the wings corresponds approximately to the depth of the paragraph on the lid.
Nach einer weiteren bevorzugten Ausführungsform ist zwischen den Flügelspitzen und der Hubkontur ein Radialspalt als Restspalt belassen, wodurch die Flügel ein radiales Spiel haben und ein einwandfreies Gleiten – ohne Klemmen – der Flügelaußenkanten an der Hubkontur und der Flügelinnenkanten an der Außenkontur sichergestellt ist. According to another preferred embodiment, a radial gap is left as a residual gap between the wing tips and the stroke contour, whereby the wings have a radial clearance and proper sliding - without terminals - the wing outer edges on the stroke contour and the wing inner edges is ensured on the outer contour.
Nach einer weiteren bevorzugten Ausführungsform bilden die radial im Rotor angeordneten Schlitze in ihrem radial innen liegenden Bereich so genannte Hinterflügelbereiche, welche mit dem Druck- oder Fördermedium beaufschlagbar sind. Dadurch wird die Auswärtsbewegung der Flügel in radialer Richtung unterstützt und gleichzeitig erreicht, dass die Flügelinnenkanten im Bereich ihres Überstandes keinen Kontakt mehr zur Außenkontur des Deckelabsatzes haben. Die Außenkanten der Flügel liegen dann voll, d. h. ohne Radialspalt an der Hubkontur an. According to a further preferred embodiment, the slots arranged radially in the rotor form in their radially inner region so-called rear wing regions, which can be acted upon by the pressure or conveying medium. As a result, the outward movement of the wings is supported in the radial direction and at the same time ensures that the wing inner edges no longer have any contact with the outer contour of the cover paragraph in the region of their projection. The outer edges of the wings are then full, d. H. without radial gap on the stroke contour.

Darüber hinaus ist die Erfindung mit Flügelüberstand ü und Absatz
Die erfindungsgemäße Flügelzellenpumpe wird bevorzugt als Getriebeölpumpe für Automatgetriebe in Kraftfahrzeugen verwendet, wobei der Rotor der Flügelzellenpumpe vom Verbrennungsmotor des Kraftfahrzeuges angetrieben wird. Beim Starten des Verbrennungsmotors kann dieser zunächst in der falschen Richtung drehen, was bei herkömmlichen Flügelzellenpumpen Probleme bereitet. Bei der erfindungsgemäßen Flügelzellenpumpe dagegen ist das kurzzeitige Rückdrehen des Rotors unkritisch, da die Flügel nicht einfallen oder zurückgedrückt werden können. Vielmehr steht nach dem Starten des Verbrennungsmotors sofort die volle Förderleistung der Getriebeölpumpe zur Verfügung, so dass Schaltelemente des Automatgetriebes hinreichend mit Drucköl versorgt sind und die einzelnen Gänge geschaltet werden können. The vane pump according to the invention is preferably used as a transmission oil pump for automatic transmissions in motor vehicles, wherein the rotor of the vane pump is driven by the internal combustion engine of the motor vehicle. When the internal combustion engine starts, it can first turn in the wrong direction, which causes problems in conventional vane pumps. In the vane pump according to the invention, however, the short-term reverse rotation of the rotor is not critical, since the wings can not fall or be pushed back. Rather, after starting the engine immediately the full capacity of the transmission oil pump is available, so that switching elements of the automatic transmission are sufficiently supplied with pressure oil and the individual gears can be switched.
