Description

Die Erfindung betrifft eine Anbaueinrichtung nach dem Oberbegriff Anspruchs 1. Solch eine Vorrichtung ist bekannt aus DE 203 19 987 U .The invention relates to a mounting device according to the preamble of claim 1. Such a device is known from DE 203 19 987 U ,

Aus der AT 77366 ist eine Einrichtung zum Anschließen von 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 parallelepipedischen 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 Kühlelemente werden außerdem von einem angebauten Ventilator mit Kühlluft beaufschlagt.From the AT 77366 a device for connecting piping to the box-shaped manifold portion of a hydraulic oil-air cooler is known, 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 are combined into a parallelepipedic packet, usually consist 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 acted upon by a mounted fan with cooling air.

Bei den bisher bekannten Hydrauliköl-Luftkühlern sind die Anschlußstutzen für die zu- und abführenden Rohrleitungen mit vorbestimmtem Anschlußquerschnitt in dem kastenförmigen Verteilerabschnitt 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 the ends thereof. 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 Hydrauliköl-Auslaßleitung, sondern auch für den Anschluß von unterschiedlichen Sekundärkomponenten eignet, wobei für alle Anschlüsse 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 an attachment 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, wherein for all connections 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 nach Anspruch 1.The invention relates to an attachment according to claim 1.

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-Luftkühlern 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 coolers of different sizes and models.
