Description

Die Erfindung betrifft einen Modulträger für diverse Wärmeübertrager eines Kraftfahrzeugmotors nach dem Oberbegriff des Patentanspruches 1.The invention relates to a module carrier for various heat exchangers a motor vehicle engine according to the preamble of Claim 1.

Ein Modulträger dieser Art ist aus der DE 198 31 256 A1 bekannt. Dort hat man in einem Querträger, der Teil des Bugbereichs eines Kraftfahrzeuges ist, einen U-förmigen Bereich vorgesehen, in den ein rechteckiger Rahmen, der insbesondere aus Kunststoff besteht, formschlüssig eingeschoben wird. Dieser Rahmen weist einen nach oben offenen U-förmigen Teil aufweist, in den ein Kühler und ein Kondensator schubladenförmig eingeschoben werden können. Diese beiden eingeschobenen Teile werden dann durch eine Deckplatte im Rahmen gehalten, die auch den Rahmen in dem U-förmigen Bereich des Querträgers hält. Der Rahmen überragt die eingeschobenen Wärmeübertrager in Fahrtrichtung nach vorne und bildet einen Luftleitrahmen. Diese Ausgestaltung macht die Anordnung eines geschlossenen Einschiebrahmens erforderlich und ist daher relativ aufwendig. A module carrier of this type is known from DE 198 31 256 A1. There you have in a cross member that part of the bow area of a motor vehicle is a U-shaped area provided in which a rectangular frame, in particular consists of plastic, is inserted form-fitting. This Frame has a U-shaped part open at the top, in which a cooler and a condenser are drawer-shaped can be inserted. These two inserted parts are then held in the frame by a cover plate also the frame in the U-shaped area of the cross member holds. The frame towers over the inserted heat exchangers forward in the direction of travel and forms an air guide frame. This configuration makes the arrangement of a closed Slide frame required and is therefore relative consuming.

Aus der DE-U 91 14 734 ist ein Modulträger bekannt, bei dem man einen einstückig aus Kunststoff gespritzten Tragrahmen für zwei von einem Elektromotor angetriebene Lüfter mit einer an einer Seite L-förmig abragenden Konsole vorgesehen hat, auf der im Abstand zu dem Tragrahmen der Kühlmittel/Luftkühler aufgesetzt und durch Tragarme mit dem Kunststoffrahmen verbunden werden kann, welche den Abstand zwischen dem Tragrahmen und dem aufgesetzten Kühlmittel/Luftkühler überbrücken. In den Zwischenraum zwischen Kühlmittel/Luftkühler und Tragrahmen kann ein Kondensator eingesetzt werden, der mit von den Tragarmen von der Konsole gehalten wird. Zusätzlich sind dort noch Befestigungsmöglichkeiten für einen Ölkühler und für eine Lüfterzarge vorgesehen. Dieser bekannte Modulträger vereinfacht zwar den Ein- und Ausbau der verschiedenen Elemente auch im Fall einer Reparatur, ist aber wegen seines doch relativ komplizierten Aufbaus sehr aufwendig.From DE-U 91 14 734 a module carrier is known in which one integrally molded plastic support frame for two fans driven by an electric motor with one provided L-shaped protruding console on one side, on the at a distance from the support frame of the coolant / air cooler attached and by support arms with the plastic frame can be connected, which is the distance between the support frame and bypass the attached coolant / air cooler. In the space between the coolant / air cooler and Support frame can be used with a capacitor is held by the bracket from the bracket. additionally there are still mounting options for an oil cooler and provided for a fan frame. This well-known module carrier simplifies the installation and removal of the various Elements even in the case of a repair, but is because of its but relatively complicated structure very complex.

Aus der DE 39 22 814 A1 ist eine andere Art einer Halterung für den Kühler eines Kraftfahrzeugmotors bekannt, bei der ein mit nur einem Wasserkasten versehener und mit U-förmigen Rohren ausgerüsteter Kühlmittel/Luftkühler vorgesehen wird, der in der Art einer Kassette in eine innerhalb der Halterung gebildete schachtartige Öffnung einschiebbar ist. Mit herkömmlichen Mitteln ist außerdem unterhalb dieser Halterung ein Ölkühler anbringbar, ebenso wie an einer Seitenwand ein Kondensator anschraubbar ist. Zum Abbau dieser zusätzlichen Teile ist eine Demontage der Halterung aus dem Fahrzeug notwendig. Dies gilt auch beim Ausbau des in die Halterung eingeschobenen Wasser/Luftkühlers.Another type of holder is known from DE 39 22 814 A1 known for the radiator of a motor vehicle engine, in which a with only one water box and with U-shaped tubes equipped coolant / air cooler is provided, the in the manner of a cassette in a formed within the holder shaft-like opening can be inserted. With conventional Means is also below this bracket Oil cooler attachable, as well as a condenser on a side wall is screwable. To dismantle these additional parts it is necessary to remove the bracket from the vehicle. This also applies when removing the inserted into the holder Water / air cooler.

Schließlich ist aus der DE 39 16 777 A1 auch noch eine Halterung für einen Lüftermantel bekannt, die in das Fahrzeug einbaubar ist und die, wenn der Wasser/Luftkühler, der dort mit zwei Wasserkästen versehen ist, zum Zweck einer Reparatur demontiert werden soll, aus dem Fahrzeug ausgebaut werden muss. In die dort vorgesehene rahmenartige Halterung ist der Wasser/Luftkühler nämlich mit seinen Seitenteilen eingesetzt und muss sowohl am unteren als auch am oberen Wasserkasten befestigt werden.Finally, a bracket is also from DE 39 16 777 A1 known for a fan jacket that can be installed in the vehicle and if the water / air cooler is there with two water boxes is provided, dismantled for repair should be removed from the vehicle. The water / air cooler is in the frame-like holder provided there namely used with its side parts and must be attached to both the lower and the upper water tank become.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Modulträger der eingangs genannten Art in einfacherer Art aufzubauen.The present invention has for its object a Module carrier of the type mentioned in a simpler way build.

Zur Lösung dieser Aufgabe wird bei einem Modulträger der eingangs genannten Art vorgesehen, dass das Abschlussteil als ein stabiler Träger ausgebildet ist, der die Seitenteile zum Tragrahmen verbindet und mit Aufnahmeeinrichtungen für einen Ölkühler versehen ist.To solve this problem, the beginning of a module carrier mentioned type provided that the end part as a stable support is formed, the side parts for Carrier frame connects and with receptacles for one Oil cooler is provided.

Diese Ausgestaltung bringt den großen Vorteil mit sich, dass ein unmittelbar in das Fahrzeug einsetzbarer Tragrahmen entsteht, der nicht an einen entsprechenden Vorbau gebunden ist. Alle im Modulträger vorhandenen Einzelelemente können nach Lösen des oberen Querträgers, der eine Art Deckel bildet, in einfacher Weise nach oben herausgezogen werden, so dass beim Aus- oder Einbau eines der Teile des Kühlermoduls erstens der Tragrahmen im Fahrzeug verbleibt und zweitens die anderen Teile völlig unberührt bleiben können. Kühlmittel-, Kältemittelkreislauf und Ölkreisläufe, wenn Ölkühler vorhanden sind, sind unabhängig voneinander, so dass auch dann, wenn ein Fluidsystem im Servicefall unterbrochen werden muss, z.B. der Kühlmittelkreis für den Kühlmittel/Luftkühler, die anderen Fluidsysteme unberührt bleiben, z.B. Kältemittel- und Ölkreisläufe.This configuration has the great advantage that a supporting frame can be inserted directly into the vehicle, that is not tied to a corresponding stem. All of the individual elements in the module carrier can be modified Loosen the upper cross member, which forms a kind of cover, in can be easily pulled out upwards so that when Removing or installing one of the parts of the cooler module The supporting frame remains in the vehicle and secondly the others Parts can remain completely untouched. Coolant, refrigerant circuit and oil circuits, if there are oil coolers, are independent of each other, so even if a Fluid system must be interrupted in the event of service, e.g. the Coolant circuit for the coolant / air cooler, the others Fluid systems remain unaffected, e.g. Refrigerant and oil circuits.

Diese Ausgestaltung bringt den weiteren Vorteil mit sich, dass die Geometrie der senkrecht abstehenden Seitenteile im Bereich des Kühlmittel/Luftkühlers und des Klimakondensators so gestaltet werden kann, dass ein Labyrinthsystem gebildet wird, das eine luftseitige Umströmung der beiden Wärmetauscher sowohl in, als auch entgegen der Fahrtrichtung verhindert. This configuration has the further advantage that the geometry of the vertically protruding side parts in Coolant / air cooler and air conditioning condenser area can be designed so that a labyrinth system is formed that is an air flow around the two heat exchangers prevented both in and against the direction of travel.

Des weiteren sind die Wärmetauscherkomponenten rundum gegen Leckluft abgedichtet.Furthermore, the heat exchanger components are completely against Leakage air sealed.

Des weiteren ermöglicht die Gestaltung des Modulträgers im vorderen Bereich dem Fahrzeughersteller einen zum Fahrzeug-Frontgitter verlaufenden Kanal zu verwenden, der das komplette Modul gegen luftseitige Umströmung abdichtet.Furthermore, the design of the module carrier in front area to the vehicle manufacturer to the vehicle front grille trending channel to use that the complete Seals module against airflow.

In Weiterbildung der Erfindung kann der obere, als Deckel dienende Träger auf der den Fächern zugewandten Seite mit elastischen Ausgleichselementen zur Anlage an den in die Fächer eingeschobenen Wärmeübertragern versehen sein. Diese Ausgestaltung ergibt eine sichere Verankerung der einzelnen Wärmeübertrager.In a further development of the invention, the upper one, as a cover serving carrier on the side facing the subjects elastic compensation elements for contact with the compartments inserted heat exchangers. This Design results in a safe anchoring of the individual Heat exchanger.

In vorteilhafter Weiterbildung kann der Ölkühler, wenn ein solcher vorgesehen ist, unmittelbar in der Innenseite des oberen Trägers angeordnet sein und zwar so, dass er den Abschluß der Einschiebefächer durch die elastischen Elemente nicht behindert. Diese Ausgestaltung bringt dann den Vorteil mit sich, dass zum Ausbau des Ölkühlers nur der obere, als Deckel wirkende Querträger abgenommen werden muss, ohne dass eine Demontage anderer Halterungsteile oder anderer Wärmeübertrager notwendig wird.In an advantageous development, the oil cooler, if one such is provided directly in the inside of the upper one Carrier be arranged so that he the End of the slide-in compartments with the elastic elements not disabled. This configuration then has the advantage with that to remove the oil cooler only the upper one, as The crossbeam acting on the cover must be removed without disassembly of other bracket parts or other heat exchangers becomes necessary.

Der als Deckel wirkende Querträger und die Seitenteile können in Ausgestaltung der Erfindung mit Befestigungselementen zur Anordnung im Fahrzeug versehen sein, wobei das Befestigungselement am Querträger als etwa lotrecht auf diesen einwirkende Befestigungsschrauben ausgebildet sein kann, die mit einem Anlageende aus elastomeren Gewindegängen versehen sind. Diese Befestigungsschrauben können daher von oben her durch einen im Fahrzeug befindlichen Träger in Richtung zum Querträger durchgeschraubt werden, bis ihr unteres Ende elastisch in einer entsprechenden Pfanne am Querträger anliegt und so die Sicherung des Modulträgers im Fahrzeug und gegen auftretende Beschleunigungskräfte übernimmt. The cross member acting as a cover and the side parts can in an embodiment of the invention with fasteners for Arrangement may be provided in the vehicle, the fastener acting on the cross member as approximately perpendicular to it Fixing screws can be formed with a End of the system are made of elastomeric threads. This Fastening screws can therefore be viewed from above with a Carrier located in the vehicle towards the cross member be screwed until its lower end resiliently in one appropriate pan on the cross member and so the Securing the module carrier in the vehicle and against occurring Accelerating forces take over.

Die Befestigungselemente an den Seitenteilen sind in an sich bekannter Weise als seitlich abstehende Lagerböcke mit gummielastischen Blöcken ausgebildet.The fasteners on the side parts are in themselves known way as laterally protruding bearing blocks with rubber-elastic Blocks formed.

In Weiterbildung der Erfindung kann in dem Tragrahmen auch ein Einschubfach für eine Gebläsezarge für einen von einem Elektromotor getriebenen Lüfter vorgesehen sein. Es können außerdem Ansetzmöglichkeiten für eine Lüfterzarge, vorzugsweise auf der von der Gebläsezarge für den vom Elektromotor getriebenen Lüfter abgewandten Seite, vorgesehen werden, und es kann schließlich auch noch ein Lenkhilfekühler im Bereich der als Boden ausgebildeten Quertraverse vorgesehen sein.In a development of the invention can also in the support frame a slot for a blower frame for one of one Electric motor driven fan may be provided. It can also possible attachments for a fan frame, preferably on that of the blower frame for that of the electric motor driven fan facing away, are provided, and Finally, there can also be a power steering cooler in the area the cross-beam designed as a floor may be provided.

In Weiterbildung der Erfindung kann schließlich bei einer Variierung des Tragrahmens ein Ladeluft/Luftkühler in einem zusätzlich angespritzten Fach im unteren Bereich angeordnet sein. Die Geometrie des Faches verhindert eine luftseitige Umströmung des Ladeluft/Luftkühlers sowohl in, als auch entgegen der Fahrtrichtung.In a further development of the invention, finally, with a variation an additional charge air / air cooler in the support frame molded compartment arranged in the lower area his. The geometry of the compartment prevents an air-side Flow around the charge air / air cooler both in and against the direction of travel.

The Blower frame 12 is parallel to the condenser 9 and Coolant / air cooler 8 held.

Die Fig. 2 zeigt dabei zur besseren Erkennbarkeit den Klima-Kondensator 9 und den Kühlmittel/Luftkühler 8 im noch nicht vollständig in die Führungen 6 und 7 eingeschobenen Zustand. Es ist aber deutlich zu erkennen, dass beide Wärmeübertrager aus dem Tragrahmen 1 nach der von der Bodentraverse 2 abgewandten Richtung aus den seitlichen Führungen 6, 7 in den Seitenteilen 3 und 4 herausgezogen werden können. Gleiches gilt für die Gebläsezarge 12.2 shows the air conditioning condenser for better visibility 9 and the coolant / air cooler 8 not yet fully inserted into guides 6 and 7. But it can be clearly seen that both heat exchangers from the support frame 1 after facing away from the floor cross member 2 Direction from the side guides 6, 7 in the Side parts 3 and 4 can be pulled out. The same applies to the blower frame 12.

Die Bodentraverse 2 ist beim Ausführungsbeispiel mit zwei Einstecklaschen 16 versehen, die dazu dienen, Einsteckzapfen 17 einer Zarge 19 aufzunehmen, die mit seitlichen Haltelaschen 18 in nicht näher gezeigte Aufnahmen an den Seitenteilen 3 und 4 einrastet. Die aus der oberen Quertraverse 5 und dem U-förmigen Tragrahmen bestehende Halterung kann daher, wie schematisch aus Fig. 1 hervorgeht, den Kühlmittel/Luftkühler 8, den Klima-Kondensator 9, die Gebläsezarge 12 für einen von einem Elektromotor getriebenen Lüfter und die den vom Motor getriebenen Lüfter umgebende Zarge 19 aufnehmen. Alle diese Teile werden dann durch die aufgesetzte obere Quertraverse 5 gehalten, die das U-förmige Unterteil 1 außerdem zu einem stabilen Rahmen ergänzt.The floor cross member 2 is in the embodiment with two Insert tabs 16 which serve to insert pins 17 to include a frame 19, the side holding tabs 18 in not shown shots on the side parts 3 and 4 clicks into place. From the upper crossbar 5 and the U-shaped support frame existing bracket can therefore 1, the coolant / air cooler 8, the air conditioning condenser 9, the blower frame 12 for a fan driven by an electric motor and the frame 19 surrounding the fan driven by the motor. All of these parts are then put on by the upper crossbar 5 held the U-shaped lower part 1 also added to a stable framework.

Fig. 1 deutet auch an, dass dieser obere deckelartige Querträger 5 - siehe hierzu auch die Fig. 4 - mit einem Ölkühler 20 versehen sein kann, der an seiner Unterseite so angebracht wird, dass er oberhalb vom Klima-Kondensator 9 noch Platz findet, ohne dass die Verschlussfunktion des oberen Querträgers 5 beeinträchtigt wird. Der obere Querträger 5 kann nämlich auf der den Fächern 6, 7, 6', 7' zugewandten Seite mit elastischen Ausgleichselementen versehen sein, die zur Anlage an den in die Fächer eingeschobenen Wärmeübertragern 8 und 9 kommen. Nach Fig. 1 kann auch die Möglichkeit vorgesehen werden, beispielsweise einen Lenkhilfekühler 21 noch zusätzlich unten im Bereich der Bodenquertraverse 2 anzusetzen, wenn dies gewünscht sein sollte. Fig. 1 also indicates that this upper lid-like cross member 5 - see also Fig. 4 - with an oil cooler 20 can be provided, which is attached to its underside that there is still space above the air conditioning condenser 9 takes place without the locking function of the upper cross member 5 is impaired. The upper cross member 5 can namely on the side facing the compartments 6, 7, 6 ', 7' elastic compensation elements are provided to the system on the heat exchangers 8 and 9 inserted into the compartments come. 1, the possibility can also be provided for example, a power steering cooler 21 additionally start at the bottom in the area of the floor crossmember 2 if this should be desired.

Die Fig. 4 und 5 lassen erkennen, dass der obere Querträger 5 an seinen beiden Enden mit nach unten ragenden Ansätzen 21 bzw. 22 versehen ist, die mit Befestigungslaschen mit Öffnungen 23 versehen sind, durch die die aus Fig. 6 und 7 ersichtlichen Schrauben 24 durchgeschoben und dann in entsprechenden Gewindelaschen 25 des Seitenteiles 3 befestigt werden. Analog wird der Ansatz 22 am Seitenteil 4 angebracht. Der gesamte Modulträger wird dann über an sich bekannte gummielastische Pufferelemente 26, die an seitlichen Abstützlaschen 27 angebracht sind, seitlich im Fahrzeug abgestützt und von oben her durch Schrauben 27 gehalten, die in dem später der Quertraverse 5 zugewandten Bereich aus Elastomer hergestellte Gewindegänge aufweisen. Diese Schrauben 27 sind in Haltepfannen 28 an der Oberseite der Quertraverse 5 eingeschraubt und durchsetzen in nicht näher dargestellter Weise einen Querträger im Fahrzeug, durch den sie nach unten durchgeschraubt werden, bis ihr elastischer Ansatz in den Haltepfannen 28 zur Anlage kommt. Der Modulträger wird daher seitlich auf den Puffern 26 elastisch getragen und von oben her ebenfalls elastisch abgesichert.4 and 5 show that the upper cross member 5th at both ends with projections 21 projecting downwards or 22 is provided with mounting tabs with openings 23 are provided, through which those shown in FIGS. 6 and 7 Screws 24 pushed through and then in appropriate Threaded tabs 25 of the side part 3 are attached. Analogous the approach 22 is attached to the side part 4. The whole Module carrier is then over known rubber-elastic Buffer elements 26, which are attached to lateral support tabs 27 are supported laterally in the vehicle and from above held by screws 27 in which later the crossbar 5 facing area made of elastomer threads exhibit. These screws 27 are in holding pans 28 screwed into the top of the crossbar 5 and push through a cross member in a manner not shown Vehicle through which they are screwed down until their elastic approach in the holding pans 28 to the plant comes. The module carrier is therefore laterally on the buffers 26 worn elastically and also elastically secured from above.

Der große Vorteil dieser in sehr einfacher Weise im Fahrzeug anzuordnenden Halterung ist, dass im Servicefall oder bei einer Reparatur die betreffenden Wärmeübertrager, also beispielsweise der Kühlmittel/Luftkühler 8 nach Lösen des oberen Querträgers 5 in einfacher Weise nach oben herausgezogen werden können, ohne dass die anderen Wärmeübertrager dadurch beeinflusst werden. So wird beispielsweise der vorhandene Ölkühler 20 durch Abnahme des Querträgers 5 mit entfernt. Seine Zu- und Ableitungen brauchen, da sie in der Regel genügend Flexibilität aufweisen, nicht abgeklemmt zu werden. Gleiches gilt für den in der Halterung verbleibenden Klima-Kondensator 5 oder auch für die anderen am Modulträger angebrachten Teile.The big advantage of this in a very simple way in the vehicle bracket to be arranged is that in case of service or at a Repair the relevant heat exchanger, for example the coolant / air cooler 8 after loosening the upper one Cross member 5 can be pulled out in a simple manner can without affecting the other heat exchangers become. For example, the existing oil cooler 20 removed by removing the cross member 5. His Supply and discharge lines need, since they are usually sufficient Have flexibility not to be pinched. The same applies to the air conditioning condenser remaining in the holder 5 or also for the other parts attached to the module carrier.
