Die Erfindung betrifft ein auf einem Fahrgestell aufgebautes Hydraulikaggregat zum Betrieb einer auf einer festen Bodenoberfläche selbstfahrenden Arbeitsmaschine durch geförderte Hydraulikflüssigkeit als Kraftübertragungsmittel, bestehend aus einem zur Aufnahme der Hydraulikflüssigkeit vorgesehenen Flüssigkeitstank und wenigstens einer zur Entnahme aus Letzterem und Rückführung der Hydraulikflüssigkeit über eine Flüssigkeitsrückflussleitung der Hydraulikflüssigkeit in den Flüssigkeitstank verbundenen, vorzugsweise elektrisch angetriebenen Förderpumpe, sowie einer zwischen Förderpumpe und wenigstens einem drehend und/oder linear angetriebenen Verbraucher der Arbeitsmaschine steuerbaren Schaltventilanordnung, die auf dem Flüssigkeitstank angeordnet sind.The invention relates to a hydraulic unit built on a chassis for the operation of a self-propelled machine on a solid floor surface using pumped hydraulic fluid as a power transmission means, consisting of a fluid tank provided for receiving the hydraulic fluid and at least one for withdrawing the hydraulic fluid and returning the hydraulic fluid to the hydraulic fluid via a fluid return line The preferably electrically driven feed pump connected to the liquid tank, as well as a switching valve arrangement which can be controlled between the feed pump and at least one rotating and / or linearly driven consumer of the working machine and which are arranged on the liquid tank.
Bei einem Hydraulikaggregat für ein Flurförderzeug nach der bekanntgewordenen
Es sind aus Metall, vornehmlich aus Baustahl durch Schweissen gebildete Flüssigkeitstanks mit aufgebauten Förderpumpen, Ventilblöcken und Filtern sowie einem Einfüllstutzen als Hydraulikaggregate bekannt.There are known liquid tanks formed from metal, primarily from structural steel by welding, with built-up feed pumps, valve blocks and filters as well as a filler neck as hydraulic units.
Bei einer mobilen/fahrbaren Anwendung ist ein aufgebautes Hydraulikaggregat mit einem Blechtank aus Baustahl relativ schwer und bei aufwändigen Fahrgestell- und Karosserieformen, wie sie bei einer Fahrzeugaussenkontur gebildet sind, beispielsweise im Radkastenbereich, sehr teuer in der Herstellung.In a mobile / drivable application, a built-up hydraulic unit with a sheet metal tank made of structural steel is relatively heavy and, in the case of complex chassis and body shapes, such as those formed in a vehicle outer contour, for example in the wheel arch area, is very expensive to manufacture.
Überdies ist ein geschweisster Flüssigkeitstank anfällig auf Korrosion, insbesondere nach einer Beschädigung an der Oberfläche, und Spannungen im Bereich der Schweissnähte führen zu Leckagen.In addition, a welded liquid tank is prone to corrosion, especially after damage to the surface, and tensions in the area of the weld seams lead to leaks.
Ein Kunststofftank weist einen erheblichen Nachteil bei der Integration von angebauten Aggregationskomponenten, wie Motoren, Pumpen und Ventilkombinationen auf, zumal die erforderlichen Befestigungskonstruktionen, beispielsweise Einlegerahmen, aufgrund der unterschiedlichen Ausdehnungskoeffizienten von Metall und Kunststoff nur in engen Abmessungen realisierbar sind, weil Temperaturschwankungen zu Stabilitätsminderung, Steifigkeitsverlust, zu Leckagen zwischen den Einlegerahmen und dem Kunststofftank führen und die vorhandene Festigkeit schwächen.A plastic tank has a significant disadvantage when integrating built-on aggregation components such as motors, pumps and valve combinations, especially since the required fastening structures, for example insert frames, can only be implemented in narrow dimensions due to the different expansion coefficients of metal and plastic, because temperature fluctuations lead to a reduction in stability and a loss of rigidity , lead to leaks between the insert frame and the plastic tank and weaken the existing strength.
Aus diesen Nachteilen resp. Erwartungen im Arbeitseinsatz hat sich an die vorliegende Erfindung die Aufgabe gestellt, ein Hydraulikaggregat zu entwickeln, das über eine hohe Zuverlässigkeit beim Gebrauch verfügt, eine einfache Montage beim Aufbau der betroffenen Aggregatskomponenten gestattet und sich als robust über eine lange Gebrauchsdauer erweist, und es sollen damit die Verschleissanfälligkeit und die Leckagegefahr weitgehend beseitigt werden können.From these disadvantages, respectively. Expectations in work use has set itself the task of the present invention to develop a hydraulic unit that has a high level of reliability in use, allows easy assembly when assembling the unit components concerned and proves to be robust over a long period of use, and it should therefore the susceptibility to wear and the risk of leakage can be largely eliminated.
Erfindungsgemäss wurde die Aufgabe dadurch gelöst, dass der Flüssigkeitstank aus einem oben offenen Behälter gebildet ist und die Förderpumpe und die mit ihr leitungsverbundene Schaltventilanordnung, die Verbindungsleitungen der Aggregatskomponenten sowie eine Flüssigkeitseinfüllöffnung als Einheit an einer die Behälteröffnung verschliessenden Verschlussplatte angeordnet sind.
Dadurch soll dem Hydraulikaggregat eine hohe Qualität der Funktionen und grössere Präzision unter den Aggregationskomponenten sowie eine einfache Montage der auf der Verschlussplatte aufgebauten Aggregatskomponenten beigemessen werden. Die Aggregatskomponenten können schon nach einer Vormontage auf der Verschlussplatte entfernt vom Behälter aufgebaut und funktionsgeprüft und anschliessend gemeinsam auf der Verschlussplatte des Flüssigkeitstanks in den Behälter eingebaut oder von diesem einzeln oder gemeinsam zur Wartung und/oder Reparatur abgenommen werden können. Die nach dem Gebrauch in den Flüssigkeitstank zurückfliessende Hydraulikflüssigkeit wird über am Ende vorzugsweise mit einem Rückflussfilter versehene eine Flüssigkeitsrückflussleitung zurückgeführt.
Aufgrund der notwendigen günstigen Zugänglichkeit kann eine Aussenwand des Behälters einen ergänzenden Teil des Fahrzeugaufbaus (Karosserieteil) der Arbeitsmaschine bilden.According to the invention, the object was achieved in that the liquid tank is formed from a container open at the top and the feed pump and the switching valve arrangement connected to it, the connecting lines of the unit components and a liquid filling opening are arranged as a unit on a closure plate closing the container opening.

The assembly components can already be assembled and function-tested after pre-assembly on the closure plate and then installed together on the closure plate of the liquid tank in the container or removed from it individually or together for maintenance and / or repair. The hydraulic fluid that flows back into the fluid tank after use is returned via a fluid return line preferably provided with a return filter at the end.
Due to the necessary favorable accessibility, an outer wall of the container can form a supplementary part of the vehicle structure (body part) of the work machine.

Es ist alternativ möglich, dass das obere Ende resp. Verbindungsende des Behälters zur Verschlussplatte durch eine zur Abdichtung zwischen Behälter und Verschlussplatte vorgesehene Befestigungsvorrichtung ausgebildet istIt is alternatively possible that the upper end, respectively. Connecting end of the container to the closure plate is formed by a fastening device provided for sealing between the container and the closure plate
Es kann zur Begünstigung der Festigkeit und Stabilität des Flüssigkeitstanks und des Behälters, dessen offener Rand zur dichten Verbindung mit der aufgesetzten Verschlussplatte verstärkt sein.To promote the strength and stability of the liquid tank and the container, its open edge can be reinforced for a tight connection with the attached closure plate.
Die zu den Aggregatskomponenten zählenden, eine Einheit bildenden Förderpumpe(n), die Schaltventilanordnung, der in den Flüssigkeitstank hineinragende Flüssigkeitsfilter, die Verbindungsleitungen und Verschraubungen und andere Armaturen sowie ein Flüssigkeitseinfüllstutzen sind vorteilhaft an der Verschlussplatte befestigt und erleichtern damit die Montage und Demontage als Einheit sowie die Unterhaltsarbeiten und Kontrollen.The unit-forming feed pump (s), the switching valve arrangement, the liquid filter protruding into the liquid tank, the connecting lines and screw connections and other fittings as well as a liquid filler neck, which are part of the aggregate components, are advantageously attached to the closure plate and thus facilitate assembly and disassembly as a unit the maintenance work and controls.
Der Behälter ist vorzugsweise einteilig ausgebildet, erfüllt seine diesbezügliche Funktion und Aufgabe jedoch auch in zweiteiliger Ausführung.The container is preferably designed in one piece, but also fulfills its function and task in this regard in a two-piece design.
Der Behälter kann bei mehrteiliger Ausführung auch in einem anderen Verfahren aus Kunststoff hergestellt sein, der sich als beständiger Werkstoff und resistent gegen Korrosion und in Anstosssituationen erweist.In the case of a multi-part design, the container can also be made of plastic in another process, which proves to be a durable material and resistant to corrosion and in impact situations.
Vorzugsweise ist die Flüssigkeitseinfüllöffnung durch einen in den flüssigkeitsfreien Raum des Flüssigkeitstanks ragenden, an der Unterseite der Verschlussplatte befestigten Einfüll- und Entlüftungsfilter ausgebildet.The liquid filling opening is preferably formed by a filling and venting filter which protrudes into the liquid-free space of the liquid tank and is attached to the underside of the closure plate.
Der Behälter ist zweckmässig kastenartig und mit einem nach einem Teilabschnitt eines Radkastens der fahrbaren Arbeitsmaschine geformten Behälterende ausgestattet, sodass er raum- und gewichtssparend und von aussen leicht zugänglich am Fahrgestell befestigt werden kann.The container is expediently box-like and equipped with a container end shaped like a section of a wheel housing of the mobile work machine, so that it can be attached to the chassis in a space-saving and weight-saving manner and is easily accessible from the outside.
Es erweist sich als günstig, wenn die erwähnten Aggregatskomponenten an der Verschlussplatte jeweils lösbar befestigt sind, sodass sie im Einzelfall an der Verschlussplatte austauschbar sind.It has proven to be advantageous if the aforementioned assembly components are each detachably attached to the closure plate, so that they can be exchanged on the closure plate in individual cases.
Vorzugsweise ist im Flüssigkeitstank oberhalb eines bestimmten Flüssigkeitsniveaus ein Einfüll- und Entlüftungsfilter angeordnet, sodass er seine Wirkung optimal entfalten kann.A filling and venting filter is preferably arranged in the liquid tank above a certain liquid level so that it can optimally develop its effect.
Es erweist sich als einfach, wenn der Behälter unterhalb der in die Flüssigkeit eingetauchten Förderpumpe(n) eine den Behälter in zwei Behälterräume verbindende Behälterverengung aufweist, die vom Behälterboden aus nach oben in den Behälter ragt und etwa unterhalb der Aggregatskomponenten endet, wodurch in den Behälterräumen eine Durchmischung der lagernden abgekühlten mit der zurückgeführten wärmeren Flüssigkeitsmenge erreicht werden kann.It turns out to be simple if the container below the feed pump (s) immersed in the liquid has a container constriction connecting the container into two container spaces, which protrudes from the bottom of the container up into the container and ends approximately below the assembly components, thereby creating the container spaces a mixing of the stored cooled with the returned warmer amount of liquid can be achieved.
Hierzu ist vorgesehen, dass die Behälterverengung durch wenigstens eine den Flüssigkeitstank in einen dem Flüssigkeitsrückfluss und eine dem Flüssigkeitsansaug zugeordnete Behälterräume unterscheidende/unterteilende Strömungsschwelle ausgebildet ist, durch welche eine laminare Mischung der zurückgeführten und der ruhenden Hydraulikflüssigkeit erzielt wird.For this purpose, it is provided that the container constriction is formed by at least one flow threshold which distinguishes / subdivides the liquid tank into a container spaces assigned to the liquid backflow and the liquid suction through which a laminar mixture of the returned and the static hydraulic fluid is achieved.
Die Strömungsschwelle(n) kann an einer Rückwand eines in den Behälter versetzten Hohlraumes vorgesehen sein und so eine Wärmeausgleichswirkung begünstigen.The flow threshold (s) can be provided on a rear wall of a cavity offset in the container and thus promote a heat equalization effect.
Vorteilhaft ist eine Saugöffnung der mit der(n) Förderpumpe(n) verbundenen Saugleitung im Behälterraum einer geringeren Flüssigkeitstemperatur als im anderen Behälterraum des Flüssigkeitstanks angeordnet.A suction opening of the suction line connected to the feed pump (s) is advantageously arranged in the container space with a lower liquid temperature than in the other container space of the liquid tank.
