Stand der TechnikState of the art

Die Erfindung betrifft eine Konditioniereinheit für Schmieröl, insbesondere in einem Kraftfahrzeug, nach dem Oberbegriff des Hauptanspruches.The invention relates to a conditioning unit for lubricating oil, in particular in one Motor vehicle, according to the preamble of the main claim.

Es sind Konditioniereinheiten für Schmieröl in einem Kraftfahrzeug bekannt, bei denen eine Ölfilteranordnung mit einem Ölfilterumgehungsventil und ein Ölkühler separat im Motorraum des Kraftfahrzeugs untergebracht sind. Diese Anordnung führt zu einem großen Herstellungsaufwand und erlaubt keine optimale Abstimmung der Einzelkomponenten aufeinander.Conditioning units for lubricating oil in a motor vehicle are known, in which an oil filter assembly with an oil filter bypass valve and an oil cooler separately are housed in the engine compartment of the motor vehicle. This arrangement leads to a large manufacturing effort and does not allow optimal coordination of the individual components each other.

Aus der US 4,174,699 ist eine Filtereinrichtung bekannt, bei der ein austauschbares Filterelement an einem Träger vorgesehen ist. Der Träger beinhaltet neben den entsprechenden Zuführ- und Abführleitungen ein Ventil für das Filterelement und ein weiteres Ventil. Ein Nachteil der bekannten Einrichtung ist darin zu sehen, dass zusätzlich zu der Einrichtung noch weitere Elemente wie beispielsweise Kühler, Kühlerbypassventil und anderes vorgesehen sein müssen, die einen erheblichen Aufwand an Flüssigkeitsleitungen bedeuten.From US 4,174,699 a filter device is known in which an exchangeable Filter element is provided on a carrier. The carrier includes in addition to the corresponding Supply and discharge lines a valve for the filter element and a another valve. A disadvantage of the known device can be seen in that in addition other elements such as radiator, radiator bypass valve and other must be provided, which requires considerable effort on liquid lines mean.

    • Beschreibung des AusführungsbeispielsDescription of the embodiment

    In Figur 1 ist ein Grundkörper 1 einer Konditioniereinheit für das Schmieröl eines Kraftfahrzeuges gezeigt, wobei in der Konditioniereinheit das zu filternde Öl durch einen Ölkühler 2 in eine Filteranordnung 3 geleitet wird (Pfeil 4). Am Grundkörper 1 der Konditioniereinheit befindet sich noch ein Einlass für ein Kühlmittel (Pfeil 5). Das Kühlmittel, in der Regel das Kühlwasser für den Verbrennungsmotor, wird durch einen Öl-Külmittel-Wärmetauscher 6 zu einem Auslass 7 geleitet. Hier ist noch ein, in der Figur 1 nicht sichtbares, Umgehungsventil für den Öl-Külmittel-Wärmetauscher 6 vorhanden. In der Filteranordnung 3 ist eine metallfreie Filterpatrone 8 als Filterelement an einem Mittelrohr 9 angeordnet. Durch die Filterpapierlagen der Filterpatrone 8 und durch Öffnungen im Mittelrohr 9 wird das Öl in das Innere des Mittelrohrs 9 und dann anschließend zum Ausgang (Pfeil 10) der Konditioniereinheit 1 geleitet.In Figure 1 is a base body 1 of a conditioning unit shown for the lubricating oil of a motor vehicle, wherein the oil to be filtered through in the conditioning unit an oil cooler 2 is passed into a filter arrangement 3 (Arrow 4). Located on the base body 1 of the conditioning unit there is still an inlet for a coolant (arrow 5). The coolant, usually the cooling water for the Internal combustion engine, is through an oil-coolant heat exchanger 6 directed to an outlet 7. Here is another bypass valve, not visible in FIG. 1 available for the oil-coolant heat exchanger 6. In the filter arrangement 3 is a metal-free filter cartridge 8 arranged as a filter element on a central tube 9. Through the filter paper layers of the filter cartridge 8 and through Openings in the center tube 9, the oil in the interior of the Middle tube 9 and then to the exit (arrow 10) of the conditioning unit 1.

    Im Mittelrohr 9 ist ein Umgehungsventil 11 angeordnet, durch das ein Ölstrom über Umgehungskanäle (Pfeile 12) an der Filterpatrone 8 vorbei zum Ausgang geleitet werden kann, beispielsweise bei einem Überdruck des Schmieröls von 2,5 bar. Eine Auslassschraube 13 für das Schmieröl ist über einen Imbus 14 aus dem Gehäuse der Filteranordnung 3 herausschraubbar, womit das in der Konditioniereinheit 1 vorhandene, eventuell auszutauschende Schmieröl abgelassen werden kann (Pfeil 15). Der Imbus 14 ist hierbei so dimensioniert, dass er beim Eindrehen der Auslassschraube 13 überdreht werden kann und somit eine Rissbildung durch ein zu großes Drehmoment in der Auslassschraube 13 aus Kunststoff verhindert wird. Die Kraft die hierbei auf das Gewinde wirkt wird außerdem durch eine Schulterabstützung im Gewindebereich aufgefangen. Die Auslassschraube 13 ist ohne Verwendung von Metalleinsätzen mit einem Kunststoffsägegewinde ausgestaltet.A bypass valve 11 is arranged in the central tube 9, through which an oil flow through bypass channels (arrows 12) the filter cartridge 8 are passed over to the exit can, for example, if the lubricating oil is under pressure of 2.5 bar. An outlet screw 13 for the lubricating oil is via an Allen key 14 from the housing of the filter arrangement 3 can be unscrewed, which means that in the conditioning unit 1 existing, possibly to be replaced Lubricating oil can be drained (arrow 15). The Imbus 14 is dimensioned so that when screwing in the Outlet screw 13 can be turned and thus a Cracking due to excessive torque in the outlet screw 13 is prevented from plastic. The power which acts on the thread is also a Shoulder support caught in the thread area. The Outlet screw 13 is without the use of metal inserts designed with a plastic saw thread.

    Aus Figur 2 ist eine Draufsicht auf den Grundkörper 1 mit der Filteranordnung 3 und dem Ölkühler 2 erkennbar. Das Kühlmittel tritt in den Grundkörper 1 gemäß Pfeil 5 ein und durchfließt den hier nicht im Detail erkennbaren Öl-Kühlmittel-Wärmetauscher 6. Das Schmieröl fließt gemäß dem Pfeil 4 in den Grundkörper 1 und durchströmt diesen durch in den Grundkörper 1 integrierte Kanäle sowie den Ölkühler 2 und die Filteranordnung, wie anhand der Figur 1 beschrieben. Auch hier ist ein Umgehungsventil 16 für die Umgehung des Öl-Kühlmittel-Wärmetauschers 6 für bestimmte Betriebsbedingungen, beispielsweise zur Öffnung bei einem Überdruck von 1 bar, vorgesehen. From Figure 2 is a plan view of the base body 1 with the filter arrangement 3 and the oil cooler 2 can be seen. The Coolant enters the base body 1 according to arrow 5 and flows through the oil-coolant heat exchanger, which cannot be seen in detail here 6. The lubricating oil flows according to the arrow 4 in the base body 1 and flows through it through channels integrated in the base body 1 and the Oil cooler 2 and the filter arrangement, as shown in the figure 1 described. Here, too, is a bypass valve 16 for bypassing the oil-coolant heat exchanger 6 for certain Operating conditions, for example for opening at an overpressure of 1 bar.

    In Figur 3 ist der prinzipielle Fluss des Schmieröls und des Kühlmittels im Zusammenhang dargestellt. Über eine Ölpumpe 17 wird das Schmieröl aus einer Ölwanne 18 (Pfeil 4) und durch den Grundkörper 1 mit dem Öl-Kühlmittel-Wärmetauscher 6 gefördert. Parallel dazu wird das Kühlmittel (Pfeil 5) ebenfalls durch den Grundkörper 1 und den Öl-Kühlmittel-Wärmetauscher 6 geleitet, wobei hier auch ein Ablasselement 19 für das Kühlmittel vorhanden ist. Über den Ölfluss im Öl-Kühlmittel-Wärmetauscher 6 ist das Umgehungsventil 16 geschaltet. Das Schmieröl wird sodann durch das Filterelement 8, bzw. über das Umgehungsventil 11 zu einem Verbrennungsmotor 20 und anschließend wieder in die Ölwanne 18 gefördert. Für das Schmieröl in der Filteranordnung 3 ist die Auslassschraube 13 vorgesehen. In Figure 3 is the basic flow of the lubricating oil and of the coolant shown in context. Over a Oil pump 17, the lubricating oil from an oil pan 18 (arrow 4) and through the base body 1 with the oil-coolant heat exchanger 6 funded. In parallel, the coolant (Arrow 5) also through the base body 1 and passed the oil-coolant heat exchanger 6, here there is also a drain element 19 for the coolant is. About the oil flow in the oil-coolant heat exchanger 6 the bypass valve 16 is switched. The lubricating oil will then through the filter element 8, or via the bypass valve 11 to an internal combustion engine 20 and then promoted again in the oil pan 18. For the Lube oil in the filter assembly 3 is the outlet screw 13 provided.
