Description

Die Erfindung betrifft ein Baukastensystem für Fluidpumpenvorrichtungen mit mindestens einem Kopplungsstück und mit mindestens einer Fluidpumpe gemäß der Merkmalsausgestaltung des Oberbegriffes des Patentanspruches 1.The invention relates to a modular system for fluid pump devices with at least one coupling piece and with at least one fluid pump according to the feature configuration of the preamble of patent claim 1.

Durch die EP 1 210 519 B1 ist eine Vorrichtung zum Pumpen von Fluid mit einer Hydraulikpumpe und einer Antriebseinrichtung bekannt, wobei die Hydraulikpumpe als Fluidpumpe eine Zahnradpumpe ist und als eigenständiges Bauteil mit verschiedenen Arten von Antriebseinrichtungen als weitere Bauteile in der Art eines Baukastensystems koppelbar und hierfür als einteiliges Kopplungsstück ausgebildet ist. Als dritte Art von austauschbaren Bauteilen dienen verschiedene Hydrauliktanks, insbesondere mit verschiedenen Tankvolumina, wobei der jeweilige Hydrauliktank als Tankeinheit von der einen Seite an das Kopplungsstück und die jeweilige Antriebseinrichtung von der anderen gegenüberliegenden Seite des Kopplungsstückes an dieses anschließbar sind. Hierzu weist das Kopplungsstück auf mindestens einer Seite ein Flanschteil auf und ferner sind Dichtmittel zwischen Kopplungsstück und Antriebseinrichtung sowie dem jeweiligen Hydrauliktank vorgesehen, um Leckagen wirksam begegnen zu können.Through the EP 1 210 519 B1 A device for pumping fluid with a hydraulic pump and a drive device is known, wherein the hydraulic pump is a gear pump as a fluid pump and can be coupled as an independent component with different types of drive devices as further components in the manner of a modular system and is designed as a one-piece coupling piece for this purpose. Various hydraulic tanks, in particular with different tank volumes, serve as the third type of interchangeable components, the respective hydraulic tank as a tank unit being connectable to the coupling piece from one side and the respective drive device being connectable to the coupling piece from the other opposite side thereof. For this purpose, the coupling piece has a flange part on at least one side and, furthermore, sealing means are provided between the coupling piece and the drive device and the respective hydraulic tank in order to be able to effectively counter leakages.

Mit der bekannten Lösung als Baukastensystem lassen sich verschiedene Arten von Kopplungsstücken mit integrierter Fluidpumpe, Antriebs- und Tankeinheiten nach Kundenwünschen zusammenstellen. Durch Einsatz von Gleichteilen als Einheiten oder Komponenten des Baukastensystems läßt sich eine hohe Variation von unterschiedlichen Ausführungsformen auf niedrigem Kostenniveau realisieren.With the known solution as a modular system, different types of coupling pieces with an integrated fluid pump, drive and tank units can be put together according to customer requirements. By using identical parts as units or components of the modular system, a high variation of different embodiments can be realized at a low cost level.

Durch die DE 198 59 286 A1 ist ein hydraulisches Kompakt-Aggregat bekannt, das von der Baulänge her besonders kurz aufbaut und preisgünstig realisierbar ist, da es mit wenig Einzelbauteilen auskommt, und ferner ist der Einsatz von konventionellen, d. h. ohne Umlenkung des Druckmittels, durchströmten Pumpen möglich. Um dies zu erreichen, ist eine sogenannte multifunktionale Flanschplatte vorgesehen, die als Bestandteil des Gehäuses des Antriebsmotors ausgeführt ist. In die Flanschplatte sind kundenspezifisch auf vorgebbaren Platzhaltern Steuerglieder, nämlich Druckregel-, Stromregel- oder Prioritätsventile in Cartridge-Bauweise einbaubar.Through the DE 198 59 286 A1 A hydraulic compact unit is known, which is particularly short in terms of overall length and can be implemented inexpensively, since it requires only a few individual components, and the use of conventional pumps, that is to say through which the pressure medium is not deflected, is possible. To achieve this, a so-called multifunctional flange plate is provided, which is designed as part of the housing of the drive motor. Control elements, namely pressure regulating, flow regulating or priority valves in a cartridge design, can be built into the flange plate according to the customer's requirements.

Die DE 15 25 417 A1 beschreibt ein gattungsgemäßes Baukastensystem für ein Pumpenaggregat, das insbesondere für eine Zentralschmieranlage vorgesehen ist. Die bekannte Lösung weist mindestens ein Kopplungsstück und mindestens eine Fluidpumpe auf, wobei innerhalb des Kopplungsstückes Verbindungsleitungen verlaufen, in die Platzhalter integriert sind für das wahlweise Einsetzen von Fluidbaukomponenten; ausschließlich in Form von Ventilen. Die Verbindungsleitungen sind bei der bekannten Lösung innerhalb des Kopplungsstückes derart miteinander verschaltet, dass zwischen zwei Anschlussstellen einer Verbindungsleitung, in die jeweils eine benachbarte Verbindungsleitung mündet, entsprechende Platzhalterstellen entstehen, in die Rückschlag- und Entlastungsventile integriert sind.The DE 15 25 417 A1 describes a generic modular system for a pump unit, which is intended in particular for a central lubrication system. The known solution has at least one coupling piece and at least one fluid pump, connection lines running inside the coupling piece, into which placeholders are integrated for the optional insertion of fluid components; exclusively in the form of valves. In the known solution, the connecting lines are interconnected within the coupling piece in such a way that corresponding placeholder positions are formed between two connection points of a connecting line, into each of which an adjacent connecting line opens, into which non-return and relief valves are integrated.

Sofern bei den vorstehend beschriebenen bekannten Baukastensystemen auf Platzhaltern in austauschbarer Weise Fluidbaukomponenten zum Einsatz kommen, handelt es sich hierbei ausschließlich um Hydraulikventile in verschiedenster Ausgestaltung. Was die Variationsmöglichkeiten anbelangt, lassen die bekannten Baukastensysteme somit noch Wünsche offen.If fluid components are used interchangeably in the known modular systems described above on placeholders, these are exclusively hydraulic valves in various designs. As far as the possible variations are concerned, the known modular systems leave nothing to be desired.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, die bekannten Baukastensysteme unter Beibehalten ihrer Vorteile, nämlich funktionssicher sowie platzsparend unterbringbar zu sein, dahingehend weiter zu verbessern, dass die Variationsmöglichkeiten von unterschiedlichen Ausführungsformen auf niedrigem Herstell-Kostenniveau noch weiter erhöht sind, um dergestalt eine flexible Fluidsteuerung für Fluidpumpenvorrichtungen zu ermöglichen.Proceeding from this prior art, the invention is based on the object of further improving the known modular systems while retaining their advantages, namely being functionally reliable and space-saving, in such a way that the possible variations of different embodiments are further increased at a low manufacturing cost level, to enable flexible fluid control for fluid pump devices.

Eine dahingehende Aufgabe löst ein Baukastensystem mit den Merkmalen des Patentanspruches 1 in seiner Gesamtheit.A related problem is solved by a modular system with the features of claim 1 in its entirety.

Dadurch, dass gemäß dem kennzeichnenden Teil des Patentanspruches 1 zumindest bei einem Teil der weiteren Platzhalter diese mit einer als Fluiddurchgang konzipierten Fluidbaukomponente besetzt sind, läßt sich direkt am Kopplungsstück und mithin an einer Fluidpumpenvorrichtung selbst eine Fluid-, insbesondere Hydrauliksteuerung realisieren, die ausgesprochen flexibel ist, indem verschiedenste Fluidbaukomponenten mit der sonstigen Fluidpumpenvorrichtung über das Kopplungsstück zusammenwirken können. Hierbei kommt um möglichst viele Variationsmöglichkeiten zu schaffen, einer als reinem Fluiddurchgang konzipierten Fluidbaukomponente im Hinblick auf die Vielzahl an geschaffenem Fluid-Anschlussmöglichkeiten besondere Bedeutung zu. Durch den zusätzlichen Einsatz von Ventilen, vorzugsweise in Cartridge-Bauform lassen sich unterschiedlichste Steuerungsaufgaben mit der Fluidpumpenvorrichtung vor Ort realisieren. Durch die Integration der Fluidbaukomponenten, sowohl in das Innere des Kopplungsstückes als auch entlang seines Außenumfanges, ist ein äußerst platzsparender Aufbau erreicht, der sich im Übrigen herstelltechnisch kostengünstig realisieren läßt. Durch die genannte Integration ergeben sich minimale Einbauabmessungen für das Gesamtsystem, so dass auch bei beengten Einbauverhältnissen an Maschinen od. dgl. die erfindungsgemäße Lösung einsetzbar ist.Characterized in that according to the characterizing part of claim 1, at least in part of the other placeholders are occupied with a fluid component designed as a fluid passage, a fluid, in particular hydraulic control can be realized directly on the coupling piece and thus on a fluid pump device itself, which is extremely flexible , in that a wide variety of fluid components can interact with the other fluid pump device via the coupling piece. In order to create as many possible variations, a fluid component designed as a pure fluid passage is particularly important in view of the large number of fluid connection options created. The additional use of valves, preferably in the form of a cartridge, allows a wide variety of different types Realize control tasks with the fluid pump device on site. By integrating the fluid components, both in the interior of the coupling piece and along its outer circumference, an extremely space-saving structure is achieved which, moreover, can be implemented economically in terms of manufacturing technology. The integration mentioned results in minimal installation dimensions for the overall system, so that the solution according to the invention can also be used in tight installation conditions on machines or the like.

Neben der Möglichkeit, über die genannten Platzhalter in der Art von Leerstellen in diese sinnfällig Fluidbaukomponenten zum Aufbau einer Fluidsteuerung zu integrieren, ist bei der erfindungsgemäßen Lösung jeweils stirnseitig an das Kopplungsstück modulartig eine Fluidpumpe angeordnet, die innerhalb der Tankeinheit liegt und gegenüberliegend ist die Antriebseinheit für die Fluidpumpe angeordnet. Auch die dahingehenden Komponenten können vom Leistungsvolumen und der Größe her unterschiedlich ausgebildet sein und sinnfällig über das Kopplungsstück miteinander zur Komplementierung der Fluidpumpenvorrichtung verbunden werden.In addition to the possibility of integrating fluid components for the construction of a fluid control system into these sensible spaces in the manner of empty spaces, in the solution according to the invention, a fluid pump is arranged on the front side of the coupling piece in a module-like manner, which is located within the tank unit and opposite is the drive unit for the fluid pump arranged. The relevant components can also be designed differently in terms of the power volume and the size and can, of course, be connected to one another via the coupling piece to complement the fluid pump device.

Dadurch, dass die Verbindungsleitungen innerhalb des Kopplungsstückes angeordnet sind, ist ein spezieller Aufbau erreicht, der im Betrieb der Vorrichtung sehr geräuscharm ist, wozu auch mit beiträgt, dass bei einer bevorzugten Ausführungsform des erfindungsgemäßen Baukastensystems das Kopplungsstück zentrisch von einer Durchgangsstelle durchgriffen ist, die dem Durchgriff eines Antriebsstranges dient, der von der Antriebseinrichtung zur Fluidpumpe führt.The fact that the connecting lines are arranged within the coupling piece, a special structure is achieved, which is very quiet in the operation of the device, which also contributes to the fact that in a preferred embodiment of the modular system according to the invention, the coupling piece is centrally penetrated by a passage point that the Passage of a drive train is used, which leads from the drive device to the fluid pump.

Die in der Fig.1 dargestellte Vorrichtung dient dem Pumpen und mithin der Förderung von Fluid, insbesondere in Form von Hydraulikmedium, mittels einer Fluidpumpe 12, die von einer Antriebseinrichtung 14 in Form eines Elektromotors antreibbar ist. Die Fluid- oder Hydraulikpumpe 12 ist dabei als eigenständiges modulares Bauteil mit verschiedenen Arten von Antriebseinrichtungen 14 als weitere Bauteile in der Art eines Baukastensystems koppelbar und hierfür greift die Fluidpumpe 12 mit Antriebseinrichtung 14 in Blickrichtung auf die Fig.1 gesehen von der vorderen Stirnseite an ein Kopplungsstück 16 an. Als weitere Art von Bauteilen können verschiedene Hydrauliktanks 18 vorgesehen sein, insbesondere mit verschiedenen Tankvolumen, wobei der jeweilige Hydrauliktank 18 in Blickrichtung auf die Fig.1 gesehen von der vorderen Stirnseite her an das Kopplungsstück 16 angreift. Ferner ragt die Fluidpumpe 12, beginnend mit ihrer Anschlußstelle, am Kopplungsstück 16 in das Innere des jeweils angeschlossenen Hydrauliktanks 18 hinein. Der grundsätzliche Aufbau von Fluidpumpenvorrichtungen gemäß der Darstellung nach der Fig.1 ist im Stand der Technik bekannt, so dass an dieser Stelle hierauf nicht mehr detailliert eingegangen wird.The in the Fig. 1 The device shown is used for pumping and therefore for conveying fluid, in particular in the form of hydraulic medium a fluid pump 12 which can be driven by a drive device 14 in the form of an electric motor. The fluid or hydraulic pump 12 can be coupled as an independent modular component with different types of drive devices 14 as further components in the manner of a modular system, and for this the fluid pump 12 with the drive device 14 engages in the direction of view Fig. 1 seen from the front end to a coupling piece 16. Various hydraulic tanks 18 can be provided as a further type of components, in particular with different tank volumes, the respective hydraulic tank 18 in the direction of view of the Fig. 1 seen from the front end engages the coupling piece 16. Furthermore, the fluid pump 12, beginning with its connection point, projects on the coupling piece 16 into the interior of the respectively connected hydraulic tank 18. The basic structure of fluid pump devices as shown in the Fig. 1 is known in the prior art, so that it will not be discussed in detail here.

Gemäß der Darstellung nach der Fig.4, die eine der Stirnansichten auf das Kopplungsstück 16 betrifft, verlaufen innerhalb des Kopplungsstückes Verbindungsleitungen 20,22,24,26 und 28. Ferner sind in die genannten Verbindungsleitungen Platzhalter 1 bis 10 als sog. Leerstellen integriert für das wahlweise Einsetzen von Fluidbaukomponenten 1 bis 10' gemäß der Darstellung nach der Fig.3.As shown in the Fig. 4 Connection lines 20, 22, 24, 26 and 28 run within the coupling piece, which relates to one of the end views of the coupling piece 16. Furthermore, placeholders 1 to 10 are integrated in the connection lines mentioned as so-called empty spaces for the optional insertion of fluid components 1 to 10 'as shown in the Fig. 3 .

Die Verschaltung von Verbindungsleitungen 20,22,24,26,28 mit den Platzhaltern 1 bis 10 ergibt sich insbesondere aus der Schaltplan- und Komponentenübersicht gemäß den Darstellungen nach den Fig.2 bzw. 3. An den jeweils mit 1 bis 10 bezeichneten Stellen der Schaltplanübersicht nach der Fig.2 können die Fluidbaukomponenten 1' bis 10' nach der Fig.3 treten, um sinnfällige Hydrauliksteuerungen zu erhalten, wie sie komplementiert in der Fig.5 als eine Ausführungsform wiedergegeben ist. Wie des weiteren die Fig.2 zeigt, ist der Schaltplan des Baukastensystems dadurch charakterisiert, dass die Verbindungsleitungen 20,22,24,26 und 28 innerhalb des Kopplungsstückes 16 derart miteinander verschaltet sind, dass zwischen zwei Anschlußstellen 30 einer Verbindungsleitung, in die jeweils eine benachbarte Verbindungsleitung mündet, mindestens ein Platzhalter 1 bis 10 integriert ist. Anstelle der Fluidbaukomponenten 1' bis 10' gemäß der Darstellung nach der Fig.3 können auch andere Fluidbaukomponenten treten, beispielsweise in Form von Filtern, Hydrospeichern, Kühleinheiten, Wärmetauschern, Kupplungs- und Abschlußstücke einschließlich Fluidverzweigungen und Meßgeräten, wie Druck- und Temperaturmeßgeräte (nicht dargestellt). Ferner besteht die Möglichkeit, anstelle der Fluidbaukomponenten 1 bis 10' andere Ventilbaukomponenten treten zu lassen oder an die bestehenden Komponenten weitere Komponenten (nicht dargestellt) anzuschließen. Die vorstehenden Bemerkungen machen jedoch deutlich, dass mit dem beanspruchten Baukastensystem in hohem Maße eine Variation an Steuerungsmöglichkeiten erreichbar ist, um den ständig wachsenden Kundenwünschen gerecht zu werden.The interconnection of connecting lines 20, 22, 24, 26, 28 with the placeholders 1 to 10 results in particular from the circuit diagram and component overview according to the representations according to Fig. 2 or 3.

Instead of the fluid components 1 'to 10' as shown in the Fig. 3 can also occur other fluid components, for example in the form of filters, hydraulic accumulators, cooling units, heat exchangers, coupling and end pieces including fluid branches and measuring devices such as pressure and temperature measuring devices (not shown). It is also possible to have other valve components replace the fluid components 1 to 10 'or to connect further components (not shown) to the existing components. The above remarks make it clear, however, that a wide range of control options can be achieved with the claimed modular system in order to meet the constantly growing customer requirements.

Wie sich des weiteren aus der Fig.4 ergibt, ist das Kopplungsstück 16 in der Art eines Anschlußflansches ausgebildet, an dessen einander gegenüberliegenden Stirnseiten zum einen die Fluidpumpe 12 und zum anderen ihre Antriebseinrichtung 14 angeordnet sind. Ferner schließt sich auf der gegenüberliegenden Seite die Tankeinheit 18 in Form des Hydrauliktanks an das Kopplungsstück 16 an. Des weiteren weist das Kopplungsstück 16 entlang seines, insbesondere vieleckförmigen (Vierkant) Außenumfanges Einmündungsstellen auf, die teilweise in die freien Enden der Verbindungsleitungen 20,22,24,26 und 28 oder in die Platzhalter 1 bis 10 einmünden und in die die jeweiligen Fluidbaukomponenten 1' bis 10' einsetzbar sind. Dabei besteht die Möglichkeit, gemäß der Darstellung nach der Fig.1 die jeweilige Fluidbaukomponente in der Art von Cartridge-Ventilen von außen in das Kopplungsstück 16 über die zuordenbaren Einmündungsstellen einzuschrauben oder bestimmte Fluidbaukomponenten, beispielsweise die Komponenten 5' und 7', beispielsweise in Form einer Blende oder einer Drossel, können bereits fest innerhalb der zuordenbaren Verbindungsleitung 22 bzw. 26 bereits integriert sein. Das Kopplungsstück 16 selbst kann gleichfalls einen modularen Aufbau haben, d.h. in der Art der Baugröße und bezogen auf die interne Fluidführung eine Baukomponente des Baukastensystems sein, um dergestalt noch weitere Variationsmöglichkeiten zu schaffen.How further from the Fig. 4 results, the coupling piece 16 is designed in the manner of a connecting flange, on the opposite end sides of which the fluid pump 12 and on the other hand its drive device 14 are arranged. Furthermore, on the opposite side, the tank unit 18 connects to the coupling piece 16 in the form of the hydraulic tank. Furthermore, the coupling piece 16 has junction points along its, in particular polygonal (square) outer circumference, which partially open into the free ends of the connecting lines 20, 22, 24, 26 and 28 or into the placeholders 1 to 10 and in which the respective fluid components 1 'to 10' can be used. There is the possibility, according to the representation according to the Fig. 1 screwing the respective fluid component in the manner of cartridge valves from the outside into the coupling piece 16 via the assignable junction points, or certain fluid components, for example components 5 'and 7', for example in the form of an orifice or a throttle, can already be fixed within the assignable connecting line 22 or 26 can already be integrated. The coupling piece 16 itself can likewise have a modular structure, ie, in terms of the size and in relation to the internal fluid guide, it can be a structural component of the modular system in order to create further possible variations in this way.

Das Kopplungsstück 16 ist zentrisch von einer Durchgangsstelle 34 durchgriffen, und zwar in der Art einer Mittenbohrung, die dazu dient, dass ein Antriebsstrang (nicht näher dargestellt) der Antriebseinrichtung 14 die Fluidpumpe 12 antreiben kann. Eine Entnahmestelle 7 (vgl. Fig.4) stellt die Fluidverbindung her von der Tankeinheit 18 über die Fluidpumpe 12, um dergestalt bevorratetes Fluid entnehmen zu können. Die genannte Entnahmestelle 7 ist von den Verbindungsleitungen 20,22,24 und 28 umgeben, die zu der Entnahmestelle 7 teilweise einander gegenüberliegend senkrecht aufeinanderstehen (vgl. Fig.4).The coupling piece 16 is penetrated centrally by a passage point 34, in the manner of a central bore, which serves to enable a drive train (not shown in more detail) of the drive device 14 to drive the fluid pump 12. A tapping point 7 (cf. Fig. 4 ) establishes the fluid connection from the tank unit 18 via the fluid pump 12 in order to be able to remove fluid stored in this way. The named removal point 7 is surrounded by the connecting lines 20, 22, 24 and 28, which are partially opposite one another perpendicular to the removal point 7 (cf. Fig. 4 ).

Wie die Darstellung nach der Fig.5 zeigt, sind dort die Platzhalter 1 bis 10 mit Fluidbaukomponenten 1' bis 10' belegt, wobei die Komponente 1' als Fluiddurchgang konzipiert ist, 2' als einstellbares Druckbegrenzungsventil, 3' als federbelastetes Rückschlagventil, 4' als Abzweigung mit Anschluß einer weiteren Ventilbaukomponente 4.1', 5' stellt wieder einen Fluiddurchlaß dar, 6' ein 2/2-Wege-Ventil, 7' eine Blende, 8' einen sog. Minimeßanschluß und die Anschlüsse 9' und 10' sind mit fluiddichten Abschlußstopfen versehen.As the representation after the Fig. 5 shows, the placeholders 1 to 10 are occupied by fluid components 1 'to 10', component 1 'being designed as a fluid passage, 2' as an adjustable pressure relief valve, 3 'as a spring-loaded check valve, 4' as a branch with connection of a further valve component 4.1 ', 5' again represents a fluid passage, 6 'a 2/2-way valve, 7' an orifice, 8 'a so-called mini measuring connection and the ports 9 'and 10' are provided with fluid-tight plugs.

Dadurch, dass das Kopplungsstück 16 weitgehend eine interne Fluidführung gewährleistet, sind etwaig auftretende Geräuschpegel durch das Gehäuse des Kopplungsstückes 16 gekammert, so dass ein sehr geräuscharmer Betrieb sichergestellt ist. Hierzu trägt auch mit bei, dass das Kopplungsstück 16 als Gußteil ausgebildet ist, was im Übrigen eine kostengünstige Herstellung des Kopplungsstückes 16 ermöglicht. Wie des weiteren die Fig.4 zeigt, ist das Kopplungsstück 16 bezogen auf seinen Außenumfang im wesentlichen viereckig ausgebildet und in Blickrichtung auf die Fig.4 gesehen nach unten hin sind vorkragende Flanschteile 36 vorhanden zum Festlegen des Baukastensystems an feststehenden Gebäudeteilen oder vorzugsweise an weiteren Vorrichtungsteilen einschließlich Maschinenkomponenten.Due to the fact that the coupling piece 16 largely ensures internal fluid guidance, any noise levels that may occur are chambered through the housing of the coupling piece 16, so that very low-noise operation is ensured. This also contributes to the fact that the coupling piece 16 is designed as a cast part, which, moreover, enables the coupling piece 16 to be produced inexpensively. Like the further Fig. 4 shows, the coupling piece 16 is substantially square with respect to its outer circumference and looking in the direction of Fig. 4 seen downwards, projecting flange parts 36 are present for fixing the modular system on fixed parts of the building or preferably on further device parts including machine components.
