Description

Anbaueinrichtung für einen Hydrauliköl-Luftkühler  Attachment for a hydraulic oil-air cooler
Die Erfindung betrifft eine Anbaueinrichtung für einen Hydrauliköl-Luftkühler . The invention relates to a mounting device for a hydraulic oil-air cooler.
Aus der AT 77366 ist eine Einrichtung zum Anschließen von The AT 77366 is a device for connecting
Rohrleitungen, an den kastenförmigen Verteilerabschnitt eines Hydrauliköl-Luftkühlers bekannt, der üblicherweise in den Rücklauf eines Hydrauliköl-Arbeitskreises eingeschaltet ist. Die vom heißen Hydrauliköl durchströmten, zu einem parallel- epipedischen Paket zusammengefaßten Kühlelemente des Kühlers bestehen üblicherweise aus Aluminiumplatten und -Stäben, die von Luftlamellen umgeben sind und mit dem sich über die Oberseite des Paketes erstreckenden kastenförmigen Hydrauliköl- Verteilerabschnitt in Strömungsverbindung stehen. Die Kühlele- mente werden außerdem von einem angebauten Ventilator mit Kühlluft beaufschlagt. Piping, known to the box-shaped manifold portion of a hydraulic oil-air cooler, which is usually turned on in the return of a hydraulic oil working circuit. The cooling elements of the radiator, through which the hot hydraulic oil flows and which form a parallel epipedal package, are usually made of aluminum plates and rods which are surrounded by air fins and in which the box-shaped hydraulic oil distributor section extending over the top of the package is in fluid communication. The cooling elements are also supplied with cooling air by an attached fan.
Bei den bisher bekannten Hydrauliköl-Luftkühlern sind die Anschlußstutzen für die zu- und abführenden Rohrleitungen mit vorbestimmtem Anschlußquerschnitt in dem kastenförmigen Ver- teilerabschnitt an dessen Enden herausgeführt. Dies erfordert, daß bei Hinzufügen weiterer Kühlerkomponenten, wie z.B. einem Ausgleichsbehälter oder einen Filter, verschiedene Hydrauliköl-Luftkühlermodelle mit unterschiedlichen Anschlüssen auf Lager gehalten werden müssen, und erschwert außerdem in vielen Fällen den Einbau des Hydrauliköl-Luftkühlers , weil derartige Anschlüsse relativ viel Platz benötigen.  In the hitherto known hydraulic oil-air coolers, the connecting pieces for the incoming and outgoing pipes with a predetermined connection cross-section are led out in the box-shaped distributor section at its ends. This requires that, when adding further cooler components, e.g. a reservoir or a filter, various hydraulic oil-air cooler models with different ports must be kept in stock, and also complicates in many cases the installation of the hydraulic oil-air cooler, because such connections require a relatively large amount of space.
Die Erfindung zielt darauf ab, die geschilderten Mängel zu vermeiden und eine Anbaueinrichtung der einleitend angegebenen Art zu schaffen, die sich nicht nur für den Anschluß der Hy- drauliköl-Auslaßleitung, sondern auch für den Anschluß von unterschiedlichen Sekundärkomponenten eignet, wobei für alle An- Schlüsse nur ein einziges Modell des Hydrauliköl-Luftkühlers und seines Verteilerabschnittes vorrätig gehalten werden muß. The invention aims to avoid the described deficiencies and to provide a mounting device of the type described in the introduction, which is suitable not only for the connection of the hydraulic oil outlet line, but also for the connection of different secondary components. Conclusions only a single model of the hydraulic oil-air cooler and its distributor section must be kept in stock.
Gegenstand der Erfindung ist eine Anbaueinrichtung für einen Hydrauliköl-Luftkühler , mit zu einem parallelepipedisehen Paket zusammengefaßten, vom Hydrauliköl durchströmte Kühlelementen, vorzugsweise aus Aluminiumplatten und -stäben, und einem sich über die eine Stirnseite des Paketes erstreckenden kastenförmigen Hydrauliköl-Verteilerabschnitt sowie einem sich über die andere Stirnseite des Paketes erstreckenden kasten- förmigen Sammelabschnitt für gekühltes Hydrauliköl; diese Einrichtung zeichnet sich erfindungsgemäß dadurch aus, daß die Anbaueinrichtung in Form eines Aluminiumgußblockes ausgebildet ist, der einerseits an einer Montageschiene des kastenförmigen Sammelabschnittes lösbar befestigt und anderseits an einen das gekühlte Hydrauliköl aufnehmenden Hydraulikölbehälter angeschlossen ist, wobei die Anbaueinrichtung einen Anschluß für eine Hydrauliköl-Saugleitung aufweist und ferner mit gesonderten Anschlüssen ausgestattet ist, die zur Verbindung der Anbaueinrichtung mit zumindest einem Leckölkreis, einem Aus- gleichsbehälter und einem Entlüftungsventil ausgebildet sind.  The invention relates to an attachment for a hydraulic oil-air cooler, combined to a parallelepipedisehen package, flowed through by the hydraulic oil cooling elements, preferably of aluminum plates and rods, and extending over the one end face of the package box-shaped hydraulic oil distributor section and a on the another box-shaped chilled hydraulic oil collecting section at the other end of the package; this device is inventively characterized in that the attachment is designed in the form of a cast aluminum block, which is releasably secured on the one hand to a mounting rail of the box-shaped collecting portion and on the other hand connected to a hydraulic oil receiving the cooled hydraulic oil, wherein the attachment means a connection for a hydraulic oil suction line and further equipped with separate connections, which are designed to connect the attachment with at least one leakage oil circuit, a compensation tank and a vent valve.
Vorzugsweise sind die Querabmessungen der Anbaueinrichtung an jene des Hydraulikölbehälters angepaßt.  Preferably, the transverse dimensions of the attachment are adapted to those of the hydraulic oil container.
Die Erfindung eignet sich speziell für LKWs mit zuschaltbarem Allradantrieb, der zur Anfahrphase benötigt wird, in welcher das Hydrauliköl sehr heiß wird und dementsprechend gekühlt werden muß. Die Anbaueinrichtung ermöglicht einen platzsparenden und übersichtlichen Anschluß aller erforderlichen Leitungen an den Hydrauliköl-Luftkühler . Die erfindungsgemäße Anbaueinrichtung kann vorteilhaft in Hydrauliköl-Luft kühlem unterschiedlicher Größen und Modelle eingebaut werden.  The invention is particularly suitable for trucks with switchable four-wheel drive, which is needed for the start-up phase, in which the hydraulic oil is very hot and must be cooled accordingly. The attachment allows a space-saving and clear connection of all necessary lines to the hydraulic oil-air cooler. The attachment according to the invention can be advantageously installed in hydraulic oil-air cool different sizes and models.
