Description
Die Erfindung betrifft einen Lüfterzusammenbau mit einem durch eine Antriebswelle mechanisch mit einem Verbrennungsmotor verbindbaren und in Drehung versetzbaren Lüfter und einem den Lüfter in Umfangsrichtung umschließenden, mit dem Verbrennungsmotor mechanisch verbundenen Lüfterring sowie ein Verfahren zu seiner Montage an einem Fahrzeug.The invention relates to a fan assembly comprising a fan which can be mechanically connected to an internal combustion engine by a drive shaft and set in rotation, and a fan ring which surrounds the fan in the circumferential direction and which is mechanically connected to the internal combustion engine, and a method for mounting it on a vehicle.
Die WO 98/037319 A zeigt einen Lüfterzusammenbau für einen Fahrzeugmotor. Der Umfang eines durch den Fahrzeugmotor angetriebenen Lüfters wird von einem Lüfterring umschlossen, der durch mehrere Halterungen am Fahrzeugmotor befestigt ist. Zwischen einem Kühler und dem Lüfterring ist ein Lüftergehäuse angeordnet, das fest mit dem Kühler verbunden ist. Zwischen dem Lüftergehäuse und dem Kühler befindet sich ein Spalt, der durch eine Dichtung aus einem elastischen Material wie Gummi geschlossen wird, um die abdichtende Funktion aufrecht zu erhalten, wenn sich der Motor und der Kühler beim Fahrzeugbetrieb gegenseitig verschieben. Hier wird der Lüfterring durch die Halterungen am Motor fixiert, so dass ein gewisser Aufwand für die Herstellung und Anbringung der Halterungen erforderlich ist.WO 98/037319 A shows a fan assembly for a vehicle engine. The circumference of a fan driven by the vehicle engine is enclosed by a fan ring secured to the vehicle engine by a plurality of brackets. Between a radiator and the fan ring a fan housing is arranged, which is firmly connected to the radiator. Between the fan housing and the radiator is a gap which is closed by a seal of a resilient material such as rubber to maintain the sealing function when the engine and the radiator mutually shift during vehicle operation. Here, the fan ring is fixed by the brackets on the engine, so that a certain effort for the manufacture and attachment of the brackets is required.
In der US 3 794 001 A wird ein anderer Lüfterzusammenbau mit einem vom Verbrennungsmotor angetriebenen Lüfter beschrieben. Der Kühler trägt ein Lüftergehäuse mit einem ringförmigen Fortsatz, in den ein dem Umfang des Lüfters benachbarter Lüfterring eingeschoben ist. Hier sind Relativbewegungen zwischen dem Lüfterring und dem Lüfter möglich, die einen relativ großen Spalt zwischen diesen Elementen erfordern, was den Wirkungsgrad des Lüfters nachteilig beeinflusst.Another fan assembly with a fan driven by the internal combustion engine is described in US Pat. No. 3,794,001 A. The radiator carries a fan housing with an annular extension into which a fan ring adjacent to the circumference of the fan is inserted. Here relative movements between the fan ring and the fan are possible, which require a relatively large gap between these elements, which adversely affects the efficiency of the fan.
Weiterhin sind Lüfterzusammenbauten bekannt, bei denen der Lüfterring fest am Kühler befestigt ist und den elektrisch betriebenen Lüftermotor und den Lüfter trägt (DE 42 44 039 A). Diese Anordnungen eignen sich insbesondere für kleinere Kühlleistungen, da der elektrische Antrieb des Lüfters hohen Aufwand erfordert und mit Verlust behaftet ist.Furthermore, fan assemblies are known in which the fan ring is fixedly secured to the radiator and the electric operated fan motor and the fan carries (DE 42 44 039 A). These arrangements are particularly suitable for smaller cooling capacities, since the electric drive of the fan requires great effort and is associated with loss.
Die der Erfindung zu Grunde liegende Aufgabe wird darin gesehen, einen einfach und preisgünstig herstellbaren Lüfterzusammenbau bereitzustellen.The object underlying the invention is seen to provide a simple and inexpensive to produce fan assembly.
Diese Aufgabe wird erfindungsgemäß durch die Lehren der Patentansprüche 1 und 8 gelöst, wobei in den weiteren Patentansprüchen Merkmale aufgeführt sind, die die Lösung in vorteilhafter Weise weiterentwickeln.This object is achieved by the teachings of claims 1 and 8, which are listed in the other claims features that further develop the solution in an advantageous manner.
Es wird vorgeschlagen, den Lüfterring mit einer drehbaren Lagerung an der Antriebswelle des vom Verbrennungsmotor mechanisch antreibbaren Lüfters zu befestigen. Dadurch erübrigen sich separate Halterungen zur Befestigung des Lüfterrings am Verbrennungsmotor. Weiterhin kann durch die Befestigung des Lüfterrings am Verbrennungsmotor ein sehr enges Spaltmaß zwischen dem Lüfter und dem Lüfterring eingehalten werden, da auch bei einer Vibration des Verbrennungsmotors keine Relativbewegung zwischen dem Lüfter und dem Lüfterring stattfindet.It is proposed to fasten the fan ring with a rotatable mounting on the drive shaft of the mechanically drivable fan of the internal combustion engine. This eliminates the need separate brackets for mounting the fan ring on the engine. Furthermore, a very narrow gap between the fan and the fan ring can be maintained by attaching the fan ring on the engine, since even with a vibration of the engine, no relative movement between the fan and the fan ring takes place.
Während die Lagerung den Lüfterring bezüglich der Längsachse der Antriebswelle in axialer und radialer Richtung abstützt, kann eine Fixierung des Lüfterrings in Umfangsrichtung durch ein indirekt mit dem Verbrennungsmotor verbundenes Lüftergehäuse erfolgen, an dem der Lüfterring mit einer Vorspannung anliegt. Die sich ergebende kraftschlüssige Verbindung hält den Lüfterring in der Drehrichtung des Lüfters fest. Auf diese Weise erübrigen sich weitere Halterungen zum Fixieren des Lüfterrings in seiner Umfangsrichtung. In einer bevorzugten Ausführungsform ist das Lüftergehäuse an einem Kühler angebracht, der im Betrieb mit von Lüfter transportierter Luft durchströmt wird. Es wäre andererseits aber auch denkbar, den Lüfterring durch einfache Verbindungsmittel mit dem Verbrennungsmotor oder einem damit verbundenen Element zu verbinden, um den Lüfterring in seiner Umfangsrichtung festzusetzen. So könnte er eine überstehende Nase aufweisen, die in eine Öffnung am Rahmen des Fahrzeugs eingreift.While the bearing supports the fan ring with respect to the longitudinal axis of the drive shaft in the axial and radial directions, a fixing of the fan ring in the circumferential direction can be effected by a fan housing connected indirectly to the internal combustion engine, against which the fan ring bears with a bias voltage. The resulting frictional connection holds the fan ring in the direction of rotation of the fan. In this way, unnecessary additional brackets for fixing the fan ring in its circumferential direction. In a preferred embodiment, the fan housing is attached to a radiator that is in operation flows through with air transported by fan. On the other hand, it would also be conceivable to connect the fan ring by simple connection means to the internal combustion engine or an element connected to it in order to fix the fan ring in its circumferential direction. So he could have a protruding nose, which engages in an opening on the frame of the vehicle.
Sich zwischen dem (durch die Lagerung und die Antriebswelle mit dem Verbrennungsmotor verbundenen) Lüfterring und dem (mit dem Kühler verbundenen) Lüftergehäuse möglicherweise ergebende Relativbewegungen werden vorzugsweise durch geeignete, flexible Entkopplungselemente aufgenommen, die zwischen dem Lüfterring und dem Lüftergehäuse angeordnet sind.Relative movements possibly arising between the fan ring (connected by the bearing and the drive shaft to the engine) and the fan housing (connected to the radiator) are preferably accommodated by suitable, flexible decoupling elements arranged between the fan ring and the fan housing.
Durch die beschriebene Befestigung kann die Lüfterhaube als rotationssymmetrisches sowie einteiliges und somit preiswertes, da keine zusätzlichen Arbeitsschritte zur Montage erforderndes Element hergestellt werden.As a result of the fastening described, the fan cowl can be produced as rotationally symmetrical as well as one-piece and thus inexpensive, since no additional work steps are required for mounting the element.
Die erfindungsgemäße Gestaltung des Lüfterzusammenbaus ermöglicht es, zunächst eine Baugruppe zu fertigen, die sich aus der Antriebswelle, dem Lüfter und dem durch die Lagerung mit der Antriebswelle verbundenen Lüfterring zusammensetzt. Diese Baugruppe wird dann in einen Zwischenraum zwischen einem Kühler mit einem Lüftergehäuse und einem Verbrennungsmotor eingefügt, so dass der Lüfterring durch den Kontakt mit dem Lüftergehäuse in seiner Umfangsrichtung fixiert wird. Die Antriebswelle wird mit dem Verbrennungsmotor verbunden.The inventive design of the fan assembly makes it possible to first manufacture an assembly that is composed of the drive shaft, the fan and the connected by the bearing with the drive shaft fan ring. This assembly is then inserted into a gap between a radiator with a fan housing and an internal combustion engine, so that the fan ring is fixed in its circumferential direction by the contact with the fan housing. The drive shaft is connected to the engine.

Auf einem Rahmen 10 eines insbesondere landwirtschaftlichen Fahrzeugs, beispielsweise eines Traktors, Teleskopladers oder einer selbstfahrenden Erntemaschine, ist ein Verbrennungsmotor 12 befestigt, vorzugsweise über Gummilager (nicht eingezeichnet). Der Rahmen trägt auch einen Kühler 14, der zur Kühlung des Verbrennungsmotors 12 und/oder anderer Aggregate des Fahrzeugs dient. Der Kühler 14 kann Öl oder Wasser als Kühlflüssigkeit verwenden. Anstelle des Kühlers 14 oder stromab oder stromauf davon oder in seitlicher oder vertikaler Richtung neben dem bzw. oberhalb des Kühler(s) 14 könnte auch ein Ladeluftkühler für einen Turbolader des Verbrennungsmotors 12 oder eine Kühleinrichtung für eine Klimaanlage oder ein Kühler für einen Hydraulikkreis des Fahrzeugs o. ä. vorgesehen sein.On a
Der Verbrennungsmotor 12 weist eine Abtriebswelle 38 auf, die sich in Richtung auf den Kühler 14 zu erstreckt. Zur Verbindung einer Antriebswelle 16 mit der Abtriebswelle 38 des Verbrennungsmotors 12 ist eine Klemmmutter 36 vorgesehen. Die Abtriebswelle 38 (oder eine weitere, nicht eingezeichnete Abtriebswelle des Verbrennungsmotors 12) dient zum Antrieb der angetriebenen Elemente des Fahrzeugs, z. B. für den Fahrantrieb, eine Zapfwelle oder Erntegutbearbeitungseinrichtungen. Auf der Antriebswelle 16 ist eine schaltbare Kupplung 18 angeordnet, um deren Umfang ein Lüfter 20 mit Schaufeln zur Luftförderung angeordnet ist. Die Kupplung 18 wird elektrisch oder hydraulisch oder thermisch betätigt und dient zum Ein- und Ausschalten oder zur stufigen oder stufenlosen Vorgabe der Drehzahl des Lüfters 20. Der Lüfter 20 stellt bei laufendem Verbrennungsmotor 12 und eingeschalteter Kupplung 18 einen Luftstrom in Richtung des Pfeils 24 durch den Kühler 14 und zum Verbrennungsmotor 12 hin bereit.The
Den äußeren Umfang des Lüfters 20 umrundet ein Lüfterring 22.The outer circumference of the
Der Lüfterring 22 bildet einen geschlossenen Ring um den Lüfter 20 und ist an seinem dem Verbrennungsmotor 12 benachbarten Ende mit Streben 26 ausgestattet, die sich radial zur Antriebswelle 16 hin erstrecken. Zwischen den Streben 26 können Freiräume gebildet oder ein Gitter angeordnet sein.The
Die Streben 26 des Lüfterrings 22 sind durch eine Lagerung 28 in Form eines Wälzlagers (z. B. Nadel- oder Kugellager) an der Antriebswelle 16 abgestützt. Die Lagerung 28 sichert den Lüfterring 22 gegen eine radiale und gegen eine axiale Bewegung gegenüber der Antriebswelle 16. Da der Lüfterring 22 an der Antriebswelle 16 gelagert ist, die auch den Lüfter 22 trägt, so dass sich keine Relativbewegungen zwischen dem Lüfter 20 und dem Lüfterring 22 ergeben, und da der Lüfterring einteilig, insbesondere aus Kunststoff, und rotationssymmetrisch und demnach mit geringen Toleranzen herstellbar ist, kann der radiale Spalt zwischen dem Lüfter 20 und dem Lüfterring 22 relativ eng gewählt werden, was einen guten Wirkungsgrad des Lüfters 20 und eine geringe Geräuschentwicklung ermöglicht.The
An der dem Lüfter 20 zugewandten Seite des Kühlers 14 ist ein Lüftergehäuse 30 befestigt, das die außerhalb des Hüllkreises des Lüfters 20 liegenden Flächen des Kühlers 14 trichterförmig abdeckt und an seiner dem Lüfterring 22 benachbarten Stirnseite ringförmig mit einem Durchmesser endet, der dem Durchmesser des Lüfterrings 22 zumindest näherungsweise entspricht. An dieser Stirnseite des Lüftergehäuses 30 ist ein Entkopplungselement 32 aus in sich elastischem Material (insb. Gummi) angebracht, das auf das Lüftergehäuse 30 aufgeschoben ist und es U-förmig umschließt (s. Figur 2). An der benachbarten Stirnseite des Lüfterrings 22 ist ein gleichartiges Entkopplungselement 34 befestigt.At the
Die Entkopplungselemente 32, 34 liegen aneinander vorgespannt an. Da der Lüfterring 22 eine Kraft auf das Lüftergehäuse 30 überträgt, sind die Entkopplungselemente 32, 34 in einem bestimmten Maße zusammengepresst. Dadurch wird der Lüfterring 22 in der Drehrichtung des Lüfters 20 fixiert. Die Dichtwirkung der Entkopplungselemente 32, 34 bleibt auf Grund ihrer Elastizität auch dann erhalten, wenn sich der Kühler 14 und mit ihm das Lüftergehäuse 30 gegenüber dem Verbrennungsmotor 12 und dem damit verbundenen Lüfterring 22 bewegt.The
Anhand der Figuren ist erkennbar, dass sich eine aus der Kupplung 18, dem Lüfter 20 und dem Lüfterring 22 bestehende Baugruppe vormontieren und dann als komplette Einheit in das Fahrzeug einbauen lässt. Es sind keine zusätzlichen Halter oder dgl. zur Befestigung des Lüfterrings am Verbrennungsmotor 12 oder am Lüftergehäuse 30 notwendig.It can be seen from the figures that a subassembly consisting of the
