Description

Hydraulikόltank für Arbeitsmaschinen Hydraulic oil tank for working machines
Die Erfindung betrifft einen Hydrauliköltank für Arbeitsmaschinen, wie Betonmischer, Kräne u.dgl.The invention relates to a hydraulic oil tank for working machines, such as concrete mixers, cranes and the like.
Verschiedene mobile Arbeitsmaschinen, wie Kräne, Betonmischer, aber auch derartige stationäre Maschinen benötigen einen Hydrauliköltank zur Speicherung des von den Hydraulikkreisen benötigten Hydrauliköls. Da das zirkulierende Hydrauliköl im Betrieb verschmutzt und erhitzt wird, muß es gereinigt und gekühlt werden. Zu diesem Zweck ist der Hydrauliköltank an einen Hydraulikölkühler angeschlossen und ein Hydraulikölfilter wird in den Hydraulikkreis eingeschaltet. Diese Vorrichtungen sind relativ sperrig und schwer, benötigen Raum, der bei Maschinen der in Frage stehenden Art knapp ist, und erfordern aufwendige Zusammenbauvorgänge .Various mobile machines, such as cranes, concrete mixers, but also such stationary machines require a hydraulic oil tank for storing the hydraulic oil required by the hydraulic circuits. Since the circulating hydraulic oil becomes dirty and heated during operation, it must be cleaned and cooled. For this purpose, the hydraulic oil tank is connected to a hydraulic oil cooler and a hydraulic oil filter is turned on in the hydraulic circuit. These devices are relatively bulky and heavy, require space that is scarce in machines of the type in question, and require expensive assembly operations.
Die vorliegende Erfindung zielt darauf ab, einen Hydrauliktank zu schaffen, bei welchem der bisher erforderliche Raum-, Gewichts- und Arbeitsaufwand vermieden wird. Die Erfindung zeichnet sich dadurch aus, daß der Hydrauliköltank ein im wesentlichen parallelepipedisches Tankgehäuse aufweist, das mit einem Hydrauliköleinlaß zu einem Hydraulikölkühler versehen ist, welcher in einer Durchtrittsöffnung des Tankgehäuses zusammen mit einem Lüftergebläse angeordnet ist, wobei der Hydraulikölkühler einen Auslaß für gekühltes Hydrauliköl aufweist, über welchen das Hydrauliköl in den Hydrauliköltank und aus diesem über einen Hydraulikölfilter und einen Sauganschluß des Tankgehäuses in den Hydraulikkreis abziehbar ist.The present invention aims to provide a hydraulic tank in which the previously required space, weight and effort is avoided. The invention is characterized in that the hydraulic oil tank has a substantially parallelepipedic tank housing, which is provided with a Hydrauliköleinlaß to a hydraulic oil cooler, which is arranged in a passage opening of the tank housing together with a fan blower, the hydraulic oil cooler having an outlet for cooled hydraulic oil, via which the hydraulic oil in the hydraulic oil tank and from this via a hydraulic oil filter and a suction port of the tank housing in the hydraulic circuit is removable.
Auf diese Weise wird ein kompakter Hydrauliköltank geschaffen, der alle erforderlichen Elemente für die Behandlung des Hydrauliköls enthält, wie Kühler und Filter, und dadurch vorteilhaft separate und sperrige Einrichtungen sowie Leitungen zu diesen vermeidet.In this way, a compact hydraulic oil tank is created, which contains all the necessary elements for the treatment of hydraulic oil, such as radiator and filter, and thereby advantageously avoids separate and bulky devices and lines to these.
Vorzugsweise ist das Tankgehäuse an seiner Oberseite mit einem Filterdeckel versehen, über welchen eine zylindrische Filterpatrone in den Hydrauliköltank einsetzbar ist.Preferably, the tank housing is provided on its upper side with a filter cover, via which a cylindrical filter cartridge can be inserted into the hydraulic oil tank.

Die Erfindung wird nachfolgend an einem Ausführungs- beispiel unter Bezugnahme auf die Zeichnungen näher erläutert.Tank housing equipped with a level indicator and a thermostat, and may also be equipped with a clogging indicator. The invention will be explained in more detail below using an exemplary embodiment with reference to the drawings.

Der in den Zeichnungen dargestellte Hydrauliköltank hat ein Tankgehäuse 1 aus Kunststoff oder Metall mit einem verschließbaren Hydrauliköleinlaß 2 und einem an einen nicht gezeigten Saugschlauch anschließbaren Sauganschluß 3 sowie einer Füllstandsanzeige 4. An der Tankoberseite ist ein Filterdeckel 5 vorgesehen und im Bereich des Tankbodens eine Entleerungsschraube 6. Im Gehäuseinneren sind ein Hydrauliköltank 7, ein Hydraulikölkühler 8 und ein patronenförmiger Hydraulikölfilter 9 vorgesehen. Im Betrieb strömt heißes, verschmutztes Hydrauliköl über den Hydrauliköleinlaß 2 in den Hydraulikölkühler 8. Das Hydrauliköl durchströmt den Kühler und wird dadurch abgekühlt, worauf es aus dem Hydraulikölkühler 8 über einen Stutzen 11 direkt in den Hydrauliköltank 7 strömt. Aus dem Hydrauliköltank 7 strömt das Hydrauliköl durch den austauschbaren patronen- förmigen Hydraulikölfilter 9, der auf einen abgewinkelten Sauganschlußstutzen aufgesteckt ist, zum Sauganschluß 3, aus welchem das gefilterte und gekühlte Hydrauliköl aus dem Tankgehäuse 1 austritt und in den Hydraulikkreis zurückkehrt. Wie die Zeichnungen zeigen, ist im Tankgehäuse 1 eine Durchtrittsöffnung 1 ' vorgesehen, in der ein Axiallüftergebläse 10 eingebaut ist, welches das den ebenfalls in der Durchtrittsöffnung 1' angeordneten Hydraulikölkühler 8 durchströmende Hydrauliköl kühlt. Im Tankgehäuse 1 ist schließlich ein Thermostat 12 eingebaut und eine nicht dargestellte einschraubbare Hydrauliköl-Verschmutzungsanzeige vorgesehen. The hydraulic oil tank shown in the drawings has a tank housing 1 made of plastic or metal with a closable Hydrauliköleinlaß 2 and connectable to a suction hose, not shown suction port 3 and a level indicator 4. At the tank top is a Filter cover 5 is provided and in the area of the tank bottom a drain plug 6. In the housing interior, a hydraulic oil tank 7, a hydraulic oil cooler 8 and a cartridge-shaped hydraulic oil filter 9 are provided. In operation, hot, dirty hydraulic oil flows via the hydraulic oil inlet 2 into the hydraulic oil cooler 8. The hydraulic oil flows through the cooler and is thereby cooled, whereupon it flows from the hydraulic oil cooler 8 directly into the hydraulic oil tank 7 via a pipe 11. From the hydraulic oil tank 7, the hydraulic oil flows through the interchangeable cartridge-shaped hydraulic oil filter 9, which is attached to an angled Sauganschlußstutzen to the suction port 3, from which the filtered and cooled hydraulic oil exiting the tank housing 1 and returns to the hydraulic circuit. As the drawings show, a passage opening 1 'is provided in the tank housing 1, in which an axial fan 10 is installed, which cools the hydraulic oil flowing through also in the passage opening 1' arranged hydraulic oil cooler 8. In the tank housing 1, a thermostat 12 is finally installed and not shown screwed hydraulic oil clogging indicator provided.
