Description

Baukastensystem modular system
Die Erfindung betrifft ein Baukastensystem mit mindestens einem Hauptventilblock, mit mindestens zwei Gruppen an Verbindungsleitungen, die an einer Stelle über eine Verbindungsleitung der einen Gruppe allesamt fluid- führend miteinander verbunden sind.The invention relates to a modular system with at least one main valve block, with at least two groups of connecting lines, all of which are connected to one another in a fluid-conducting manner via a connecting line of the one group.
Durch die DE-OS 27 50 035 ist ein hydraulischer Baukasten bekannt bestehend aus kleinen höhen- und flächenverkettbaren hydraulischen Elementen mit druck- und/oder mengenverändernden bzw. verteilenden oder steuernden Funktionen und einem Grundblock, wobei das Anschlußbild der Ele- mente und des Grundblocks punktsymmetrisch gestaltet und durch zwei Anschlußbohrungen und zwei Befestigungsbohrungen gebildet ist und wobei ferner die Elemente und der Grundblock in vorbestimmter Zuordnung und/oder Folge sowie um die Längsachse um 180° verdreht aufeinander angeordnet sind. Dergestalt ergibt sich ein platzsparender Aufbau für die genannten miteinander verkettbaren hydraulischen Elemente.From DE-OS 27 50 035 a hydraulic modular system is known consisting of small hydraulic elements that can be linked in terms of height and area, with pressure and / or quantity changing or distributing or controlling functions and a basic block, the connection diagram of the elements and the basic block being point symmetrical designed and formed by two connecting bores and two mounting bores and wherein the elements and the base block are arranged in a predetermined assignment and / or sequence and rotated about the longitudinal axis by 180 °. This results in a space-saving structure for the hydraulic elements which can be linked together.
Durch die EP 0 854 982 B1 ist ein modular aufgebauter Hauptventilblock bekannt eines vorgesteuerten Sitz- und/oder Kolbenventile aufweisenden Ventil Systems, der sowohl eine genormte Anschlußschnittstelle als auch eine Pilotventilschnittstelle zur Aufnahme eines Pilotventils aufweist und der eine Pump-, eine Tank-, eine erste Arbeitsleitung, eine zweite Arbeitslei- tung, eine erste Steuerleitung und eine zweite Steuerleitung aufweist und in dem vier Ventilaufnahmen zur Aufnahme von je einer Ventileinheit angeordnet sind. Die dahingehende Lösung hat sich insbesondere für die Car- tridge-Technik als geeignet erwiesen, bei der für den jeweiligen Anwen- dungsfall geeignete Ventileinheiten (Cartridges) an den Hauptventilblock angebaut werden.EP 0 854 982 B1 discloses a modularly constructed main valve block of a pilot-operated valve and seat valve and / or piston valve system, which has both a standardized connection interface and a pilot valve interface for receiving a pilot valve and which has a pump, a tank and a first work leader, a second work leader device, a first control line and a second control line and in which four valve receptacles are arranged for receiving one valve unit each. The solution in question has proven to be particularly suitable for cartridge technology, in which valve units (cartridges) suitable for the respective application are attached to the main valve block.
Durch die DE 199 21 436 A1 ist eine Hydraulikanlage zur Versorgung eines Hydraulikverbrauchers bei Kraftfahrzeugen bekannt, mit der der Auf- wand zur Ausbildung unterschiedlicher Varianten reduziert ist. Bei der bekannten Hydraulikanlage ist ein Druck- oder Hydrauliktank vorgesehen, in dem ein Hydraulikmittel bevorratet und mit Druck beaufschlagbar ist, wobei als Trägergehäuse ausgebildet sämtliche Bestandteile der Hydraulikanlage derart anbringbar sind, dass diese eine komplett montierbare Montage- einheit bilden. Des weiteren weist die bekannte Lösung eine Hydraulikmittel-Pumpe auf, die das Hydraulikmittel aus dem Drucktank oder in den Drucktank fördert, wobei ferner ein Elektromotor vorgesehen ist zum Antrieb der Hydraulikmittel-Pumpe sowie ein Steuergerät, das eine Steuerung zur Betätigung des Elektromotors enthält. Dabei ist ein Druckspeicher, der Druck in Form potentieller Energie speichert und das Hydraulikmittel des Drucktanks mit diesem Druck beaufschlagt sowie das Pumpenmodul im Inneren des Drucktanks und die sonstigen Module außen am Drucktank angebracht. Mit der dahingehend bekannten Lösung einer Hydraulikanlage ist ein modular aufgebautes Baukastensystem realisiert, mit dem sich eine Vielzahl an Aufgaben lösen läßt.From DE 199 21 436 A1, a hydraulic system for supplying a hydraulic consumer in motor vehicles is known, with which the effort for designing different variants is reduced. In the known hydraulic system, a pressure or hydraulic tank is provided, in which a hydraulic medium can be stored and pressurized, wherein all components of the hydraulic system can be attached in the form of a carrier housing in such a way that they form a completely mountable assembly unit. Furthermore, the known solution has a hydraulic medium pump which conveys the hydraulic medium from the pressure tank or into the pressure tank, an electric motor also being provided for driving the hydraulic medium pump and a control device which contains a control for actuating the electric motor. There is a pressure accumulator that stores pressure in the form of potential energy and applies this pressure to the hydraulic medium of the pressure tank, as well as the pump module inside the pressure tank and the other modules outside on the pressure tank. With the known solution of a hydraulic system, a modular system is realized, with which a variety of tasks can be solved.
Die bekannten Lösungen sind jedoch nicht geeignet, den zusehends komplexer werdenden Systemanforderungen an Hydraulikanlagen gerecht zu werden. Der Steuerungsaufwand für dahingehende hydraulische Steuerun- gen nebst den zuordenbaren Anlagenteilen ist derart gewachsen, dass man heute in Abkehr von modular aufbauenden Konzepten verstärkt Einzellösungen sucht, weil die bekannten Module oder Komponenten zur Kople- mentierung eines hydraulischen Baukastens regelmäßig nicht ausreichen, um dem dahingehend gestiegenen System- und Steueraufwand gerecht zu werden.However, the known solutions are not suitable for meeting the increasingly complex system requirements for hydraulic systems. The control effort for this hydraulic control In addition to the system parts that can be assigned, the company has grown so much that today, in departure from modular concepts, one is increasingly looking for individual solutions because the known modules or components for coupling a hydraulic modular system are usually not sufficient to cope with the increase in system and control costs ,
Ausgehend von diesem Stand der Technik liegt daher der Erfindung die Aufgabe zugrunde, die bekannten Lösungen dahingehend weiter zu verbes- sern, dass ein Baukastensystem geschaffen ist, das sich kostengünstig und in platzsparender Weise realisieren läßt, das funktionssicher im Gebrauch ist und das den gestiegenen Anforderungen an die Komplexität an möglichen Aufgabenstellungen für ein dahingehendes hydraulisches Gesamtsystem gerecht wird. Eine dahingehende Aufgabe löst ein Baukastensystem mit den Merkmalen des Patentanspruches 1 in seiner Gesamtheit.Proceeding from this prior art, the object of the invention is therefore to further improve the known solutions to the effect that a modular system is created which can be implemented inexpensively and in a space-saving manner, which is functionally reliable in use and which meets the increased requirements in terms of the complexity of possible tasks for an overall hydraulic system. 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 mindestens zwei weitere Verbindungsleitungen dieser einen Gruppe jeweils mit einer zuordenbaren Verbindungsleitung der anderen Gruppe des Hauptventilblocks verbunden sind, dass für den Einsatz vorgebbarer Ventilkomponenten mindestens drei Platzhalter in die Verbindungsleitungen der anderen Gruppe geschaltet sind, und dass mindestens zwei weitere Platzhalter zwischen eine gemeinsame Verbindungsleitung der anderen Gruppe und jeweils einer anderen zuordenbaren Verbindungsleitung dieser ande- ren Gruppe geschaltet sind, ist ausgehend von dem Hauptventilblock als Hauptkomponente des angesprochenen Baukastensystems eine Platzhalterlösung geschaffen, die es erlaubt, in Abhängigkeit der jeweiligen Systemaufgabe und in Abhängigkeit der ansonsten anzubauenden Komponenten des Baukastensystems einzelne Ventilkomponenten für jeden Platzhalter zu benutzen, die dann insgesamt auch mit den anderen Komponenten die jeweils gesetzte Systemaufgabe lösen. Die angesprochenen Platzhalter bilden in Verbindung mit den angesprochenen Verbindungsleitungen für den Hauptventilblock eine Art Matrixaufbau aus mit Quer- und Längsreihen, wobei die erfindungsgemäße Platzhalterlösung nebst dem matrixartigen Verbindungsaufbau über die Verbindungsleitungen es ermöglicht, einer ausgesprochene Vielzahl an Systemaufgaben gerecht zu werden. Die dahingehende Lösung ist auch platzsparend in ihrem Aufbau; somit kostengünstig zu realisieren und im übrigen funktionssicher in der Anwendung. Einmal im Einsatz befindliche Hauptventilblöcke als Grundsystem für den jeweiligen hydraulischen Baukasten lassen sich darüber hinaus vor Ort leicht umbauen, sofern geänderte Systemaufgaben dies notwendig erscheinen lassen.Characterized in that according to the characterizing part of claim 1 at least two further connecting lines of this one group are each connected to an assignable connecting line of the other group of the main valve block, that at least three placeholders are connected in the connecting lines of the other group for the use of predeterminable valve components, and that At least two further placeholders are connected between a common connecting line of the other group and a different assignable connecting line of this other group, starting from the main valve block as the main component of the modular system mentioned, a placeholder solution is created that allows, depending on the respective system task and in Depending on the components of the modular system that are otherwise to be fitted, individual valve components for each placeholder use, which then solve the set system task with the other components. The addressed placeholders form in connection with the mentioned connecting lines for the main valve block a kind of matrix structure with transverse and longitudinal rows, whereby the placeholder solution according to the invention, in addition to the matrix-like connection structure via the connecting lines, enables a pronounced variety of system tasks to be performed. The solution in question is also space-saving in its structure; thus inexpensive to implement and, moreover, functionally reliable in use. Main valve blocks that are in use as the basic system for the respective hydraulic modular system can also be easily converted on site, if changed system tasks make this appear necessary.
Vorzugsweise ist des weiteren vorgesehen, dass mindestens ein Platzhalter von einer Ventilkomponente unbesetzt bleibt oder den jeweiligen fluidfüh- renden Weg einer oder mehrerer Verbindungsleitungen der einen oder der anderen Gruppe sperrt oder einen fluidführenden Weg zwischen Verbindungsleitungen der anderen Gruppe bildet. Während die anderen Platzhal- ter demgemäß mit Ventilkomponenten beaufschlagt sind, erlaubt der dahingehend frei gebliebene Platzhalter eine sinnfällige Fluidsteuerung innerhalb des Hauptventilblockes in Abhängigkeit von der Systemaufgabe.It is also preferably provided that at least one placeholder remains unoccupied by a valve component or blocks the respective fluid-carrying path of one or more connecting lines of one or the other group or forms a fluid-carrying path between connecting lines of the other group. While the other placeholders are accordingly acted upon by valve components, the placeholder that has been left free in this regard permits a sensible fluid control within the main valve block depending on the system task.

The circuitry solution according to FIG. 2 has a pressure relief valve 22 for each of the two right placeholders 18, as seen in the direction of view of the figure, and one on the left
Bildhälfte ist der Platzhalter 18 mit einem Rückschlagventil 24 besetzt. Der rechte Platzhalter 20 ist mit einer einstellbaren Drossel 26 versehen und der ganz linke weitere Platzhalter 20 erlaubt einen fluidführenden Weg 28 zwischen Verbindungsleitungen 14,14b der dahingehenden anderen Gruppe.Half of the picture is the placeholder 18 with a check valve 24. The right placeholder 20 is provided with an adjustable throttle 26 and the leftmost placeholder 20 allows a fluid-carrying path 28 between connecting lines 14, 14b of the other group in question.
Bei einer entsprechend geänderten Ausführungsform nach der Fig.3 können die dahingehenden Platzhalter 20 auch mit einer den Fluidweg 28 sperrenden Einrichtung 30 versehen sein oder bei einer nicht näher dargestellten Ausführungsform kann ein dahingehender Platzhalter 18, vorzugsweise je- doch 20, auch vollständig unbesetzt bleiben, je nachdem, welches hydraulische Gesamtsystem man realisieren möchte.In a correspondingly modified embodiment according to FIG. 3, the relevant placeholders 20 can also be provided with a device 30 blocking the fluid path 28, or in the case of an embodiment not shown in detail, a relevant placeholder 18, preferably however 20, can also remain completely empty. depending on which overall hydraulic system you want to implement.

Fig.1) zum wahlweisen oder teilweise gemeinsamen An- schließen von weiteren Komponenten, wie Manometern 34, Hydropumpen 36 mit Elektroantrieb 60, Kühlereinheiten 38 (vgl. Fig.5), Filtereinheiten 40, Hydrospeichern 42, weiteren Ventilkomponenten 44, Hydrauliktanks 46, elektrischen und elektronischen Steuerkomponenten 48 (s. Fig.2) sowie von mindestens einem Zwischen- oder Nebenanschlußblock 50 (s. Fig.4). Wie die einzelnen Schaltpläne zeigen, kann der jeweilige Platzhalter 18,20 Ventilkomponenten aufweisen, wie Druckbegrenzungsventile 22, Rückschlagventile 24, Drosseln 26 oder Blenden sowie Schaltventile 52, beispielsweise in Form des 4/3-Wege-Ventils nach der Fig.3, oder in der Art von Druckwaagen 54 (vgl. Fig.4).Furthermore, the main valve block has connection points 32 on the outer circumference side (see FIG. 1) for optionally or partially jointly connecting further components, such as pressure gauges 34, hydraulic pumps 36 with an electric drive 60, cooler units 38 (see FIG. 5), filter units 40, hydraulic accumulators 42, further valve components 44, hydraulic tanks 46, electrical and electronic control components 48 (see FIG. 2) and at least one intermediate or auxiliary connection block 50 (see FIG. 4).
