Description

Die Erfindung betrifft eine Anordnung zur Abdichtung eines Lüfters nach dem Oberbegriff des Patentanspruches 1 - bekannt durch die DE-A 198 03 502 der Anmelderin.The invention relates to an arrangement for sealing a fan according to the preamble of claim 1 - known by the DE-A 198 03 502 the applicant.

Bei der durch die DE-A 198 03 502 bekannten Lüfteranordnung wird der Lüfter durch die Brennkraftmaschine eines Kraftfahrzeuges angetrieben und ist daher "motorfest" gelagert. Der Lüfter läuft in einer Zarge einer Lüfterhaube um, welche an einem Kühler befestigt ist, der seinerseits gegenüber der Karosserie des Fahrzeuges abgestützt ist, die Lüfterzarge ist daher "fahrzeugfest". Infolge der Relativbewegungen des Motors gegenüber der Fahrzeugkarosserie muss ein größerer Spalt zwischen den Lüfterblattspitzen und der Zarge eingehalten werden, welcher bei der bekannten Anordnung durch eine so genannte Bürstendichtung abgedichtet wird. Letztere besteht aus einer ringförmigen Halterung, welche etwa radial nach innen stehende flexible Dichtelemente bzw. Borsten aufweist und an der Lüfterzarge befestigt ist. Ähnliche Bürstendichtungen wurden auch durch die DE 86 14 073 U1 , die DE 33 39 059 A1 und die US-A 4,398,508 bekannt. Nachteitig ist die Art der Befestigung der Halterung an der Zarge, z. B. durch Kleben.At the by the DE-A 198 03 502 known fan assembly, the fan is driven by the internal combustion engine of a motor vehicle and is therefore "motor-fixed" stored. The fan runs in a frame of a fan cover, which is attached to a radiator, which in turn is supported against the body of the vehicle, the fan frame is therefore "vehicle-fixed". As a result of the relative movements of the engine relative to the vehicle body, a larger gap between the fan blade tips and the frame must be maintained, which is sealed in the known arrangement by a so-called brush seal. The latter consists of an annular holder, which has approximately radially inwardly standing flexible sealing elements or bristles and is attached to the fan cowl. Similar brush seals were also used by the DE 86 14 073 U1 , the DE 33 39 059 A1 and the US-A 4,398,508 known. Nachteitig is the type of attachment of the bracket to the frame, z. B. by gluing.

Die Druckschrift DE 4444037 A1 , die als nächstliegender Stand der Technik augesehen wird, offenbart die Merkmale des Oberbegriffs des Anspruchs 1.The publication DE 4444037 A1 , which will be the closest prior art, discloses the features of the preamble of claim 1.

Es ist Aufgabe der vorliegenden Erfindung, eine Anordnung zur Abdichtung eines Lüfters der eingangs genannten Art dahingehend zu verbessern, dass sie zu geringeren Kosten herstellbar und einfach montierbar ist.It is an object of the present invention to improve an arrangement for sealing a fan of the type mentioned in that it can be produced at low cost and easy to install.

Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Erfindungsgemäß ist vorgesehen, dass die ringförmige Halterung, welche die flexiblen Dichtelemente bzw. Borsten einer Bürstendichtung trägt, in die Zarge einclipsbar ist. Durch diese Art der Befestigung wird der Vorteil niedriger Herstellkosten und einer einfachen, schnellen und positionsgenauen Montage erreicht. Die Elemente für eine Clipsverbindung sind in der Regel einfach ausgebildet, sie können sowohl an der Zarge als auch an der Halterung angebracht sein und sind somit leicht herstellbar, insbesondere, wenn es sich um Kunststoffspritzteile handelt.This object is solved by the features of claim 1. According to the invention, it is provided that the annular holder, which carries the flexible sealing elements or bristles of a brush seal, can be clipped into the frame. By this type of attachment, the advantage of low manufacturing costs and a simple, fast and positionally accurate assembly is achieved. The elements for a clip connection are usually simple, they can be mounted both on the frame and on the holder and are thus easy to manufacture, especially if it is plastic injection molded parts.

Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen. Danach sind an der Zarge, welche einen hohlzylindrischen Bereich aufweist, Halte- und Rastelemente angeordnet, wobei diese vorzugsweise abwechselnd über den Umfang verteilt sind. Die Rastelemente sind als Rastnasen ausgebildet, welche mit Rastösen verrastbar sind, welche an der ringförmigen Halterung angespritzt sind. Die Halteelemente können als Haken oder Ringnutsegmente ausgebildet sein, welche sich nur über Teile des gesamten Umfanges erstrecken. Damit ergibt sich die Möglichkeit, die Halterung mit den Bürsten von hinten, d. h. in Richtung des Kühlers in die Zarge einzusetzen und einzuclipsen. Die Rastnasen weisen dabei vorzugsweise nach innen (zur Mitielachse) gerichtete Keilflächen auf, auf welchen die Ösen der Halterung beim Einclipsen aufgleiten, nach innen verformt werden, nach Passieren der Rastnasen wieder nach außen schnappen und verriegeln. Damit ist eine axiale Sicherung der ringförmigen Halterung gegeben.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung ist die ringförmige Halterung in Umfangsrichtung mindestens einmal geteilt, d. h. in einer oder mehreren radialen Ebenen. Vorzugsweise ist der gesamte Haltering in drei Segmente, insbesondere zu 120 Grad Zentriwinkel, oder in vier Segmente, insbesondere zu 90 Grad, aufgeteilt. Damit ergibt sich der Vorteil einer einfacheren Herstellung; man benötigt keine großen Spritzwerkzeuge in der Größenordnung des Lüfterdurchmessers, sondern kleinere Werkzeuge, was die Herstellung verbilligt und die Handhabbarkeit der Teile vereinfacht. Für diese geteilten Ringsegmente sind die Halteelemente an der Zarge so ausgebildet, dass sie zusätzlich eine radiale Sicherung bilden, was durch die hakenförmige oder ringnutförmige Ausbildung (Ringnutsegmente) erreicht wird. Durch die Rastelemente in Form von Rastnasen und Rastösen an den Segmenten wird auch eine Sicherung in Umfangsrichtung, d. h. gegen Verdrehen erreicht.Advantageous embodiments of the invention will become apparent from the dependent claims. Thereafter, holding and locking elements are arranged on the frame, which has a hollow cylindrical region, wherein these are preferably alternately distributed over the circumference. The locking elements are designed as latching lugs, which can be latched with latching eyelets, which are molded onto the annular support. The holding elements may be formed as hooks or annular groove segments, which extend only over parts of the entire circumference. This results in the possibility of inserting and clipping the holder with the brushes from behind, ie in the direction of the radiator in the frame. The detents preferably have inwardly (to Mitielachse) directed wedge surfaces on which the eyelets of the holder slip during clipping, are deformed inwards, after passing the locking lugs again snap outwards and lock. For an axial securing of the annular holder is given.
According to a further advantageous embodiment of the invention, the annular holder is divided at least once in the circumferential direction, that is, in one or more radial planes. Preferably, the entire retaining ring is divided into three segments, in particular to 120 degrees Zentriwinkel, or into four segments, in particular to 90 degrees. This results in the advantage of easier production; you do not need large injection tools in the order of the fan diameter, but smaller tools, which makes the production cheaper and simplifies the handling of the parts. For these split ring segments, the retaining elements on the frame are formed so that they additionally form a radial securing, which is caused by the hook-shaped or ringnutförmige training (Ringnutsegmente) is achieved. By the locking elements in the form of locking lugs and detents on the segments and a backup in the circumferential direction, ie, achieved against rotation.

Fig. 1 zeigt in perspektivischer Darstellung eine Lüfterhaube 1, welche einen etwa rechteckförmigen Grundriss aufweist, der an einen nicht dargestellten Kühler oder Modulträger oder dergleichen eines Kraftfahrzeuges angepasst ist, an welchem die Lüfterhaube 1 befestigt werden kann. Ausgehend von dem etwa rechteckförmigen Grundriss, verjüngt sich die Lüfterhaube 1 zu einer kreisförmigen Zarge 2, in welcher ein nicht dargestellter Lüfter, vorzugsweise ein Axiallüfter oder auch ein ummantelter Axiallüfter, so genannter Mantellüfter umläuft, weicher vom Motor eines Kraftfahrzeuges antreibbar ist. Der nicht dargestellte Lüfter fördert bzw. saugt Luft durch den nicht dargestellten Kühler. Um den Wirkungsgrad des Lüfters zu erhöhen und insbesondere eine Rezirkulation von Luft zu vermeiden, muss der Lüfter gegenüber der Zarge abgedichtet werden, worauf nachfolgend eingegangen wird. Fig. 1 shows a perspective view of a fan cover 1, which has an approximately rectangular plan, which is adapted to a not shown radiator or module carrier or the like of a motor vehicle, on which the fan cover 1 can be attached. Starting from the approximately rectangular plan, the fan cover 1 tapers to a circular frame 2, in which a non-illustrated fan, preferably an axial fan or a sheathed axial fan, so-called shell fan rotates, softer by the engine of a motor vehicle is driven. The fan, not shown promotes or sucks air through the radiator, not shown. In order to increase the efficiency of the fan and in particular to avoid a recirculation of air, the fan must be sealed against the frame, which will be discussed below.

Fig. 2 zeigt die Lüfterhaube 1 gerpäß Fig. 1, wobei in die Zarge 2 ein so genannter Bürstenring 3 zur Abdichtung des Lüfters eingesetzt ist. Erfindungsgemäß erfolgt das Einsetzen des Bürstenringes 3 in die Zarge 2 durch Einclipsen, d. h. es sind keine zusätzlichen Befestigungsmittel notwendig. Fig. 2 shows the fan cover 1 gerpäß Fig. 1 , wherein in the frame 2, a so-called brush ring 3 is used to seal the fan. According to the invention, the insertion of the brush ring 3 in the frame 2 by clipping, ie there are no additional fastening means necessary.

Fig. 3 zeigt einen Teil des Bürstenringes 3, nämlich ein Segment 4, welches sich etwa über einen Umfangsbereich von 90 Grad erstreckt und an der Innenwand der Lüfterzarge 2 befestigt, d. h. eingeclipst ist. Der gesamte Bürstenring 3 ist somit in drei Segmente geteilt, welche im Wesentlich gleich ausgebildet und über den Umfang verteilt an der Zarge 2 befestigt sind. Die Borsten der Bürstendichtung sind weggelassen - die Segmente bilden die Halterung für die Borsten. Die Art der Befestigung wird aus den folgenden Figuren deutlich, wobei einerseits Rastelemente in Form von Rastnasen 5 und andererseits Halteelemente in Form von Ringnutsegmenten 6 an der Lüfterzarge 2 vorgesehen sind. Zarge und Segmente sind als Kunststoffspritzteile ausgebildet. Fig. 3 shows a portion of the brush ring 3, namely a segment 4, which extends approximately over a peripheral region of 90 degrees and attached to the inner wall of the fan frame 2, that is clipped. The entire brush ring 3 is thus divided into three segments, which are substantially the same design and distributed over the circumference are attached to the frame 2. The bristles of the brush seal are omitted - the segments form the support for the bristles. The type of attachment will become apparent from the following figures, on the one hand locking elements in the form of locking lugs 5 and on the other hand holding elements in the form of Ringnutsegmenten 6 are provided on the fan frame 2. Frame and segments are designed as plastic injection molded parts.

Fig. 4 zeigt einen Teil der Clipsverbindung gemäß Fig. 3, nämlich die Lüfterzarge 2 vor der Verclipsung. Die Rastnasen 5 sind an der Innenwand der Lüfterzarge 2 angespritzt und stehen radial nach innen (in Richtung der Mittelachse) vor. Ebenso sind abwechselnd Ringnutsegmente 6 an die Lüfterzarge 2 angespritzt. Fig. 4 shows a part of the clip connection according to Fig. 3 namely the fan frame 2 before the clipping. The locking lugs 5 are molded onto the inner wall of the fan frame 2 and protrude radially inwards (in the direction of the central axis). Likewise, annular groove segments 6 are molded onto the fan frame 2 alternately.

Fig. 5 zeigt das Segment 4 des Bürstenringes 3, wobei zwei Rastösen 7 vorgesehen sind, welche einen sich in Umfangsrichtung ersteckenden Schlitz 7a aufweisen. Fig. 5 shows the segment 4 of the brush ring 3, wherein two locking eyes 7 are provided, which have a circumferentially ersteckenden slot 7a.

Fig. 6 zeigt einen Schnitt entlang der Linie VI-VI in Fig. 3, d. h. die Clips- bzw. Rastverbindung zwischen Rastnase 5 und Rastöse 7. Die in der Rastöse 7 eingerastete Rastnase 5 bewirkt somit eine formschlüssige Sicherung des Segments 4 in axialer Richtung und in Umfangsrichtung. Fig. 6 shows a section along the line VI-VI in Fig. 3 , ie the clips or latching connection between latching lug 5 and 7 locking lug. The latched in the detent 7 locking lug 5 thus causes a positive locking of the segment 4 in the axial direction and in the circumferential direction.

Fig. 7 zeigt einen Teil der Zarge 2 ohne Segment 4, wobei die Zarge 2 eine hohlzylindrische Innenfläche 2a aufweist, von welcher die Rastnasen 5 und die Ringnutsegmente 6 radial nach innen abstehen. Die Rastnasen 5 weisen jeweils schräge Keilflächen 5ä auf, auf weicher die Ösen 7 beim Einsetzen in die Zarge 2 aufgleiten und vorübergehend radial nach innen verformt werden. Fig. 7 shows a portion of the frame 2 without segment 4, wherein the frame 2 has a hollow cylindrical inner surface 2a, from which the locking lugs 5 and the Ringnutsegmente 6 protrude radially inwardly. The locking lugs 5 point each oblique wedge surfaces 5ä, on the softer the eyelets 7 slide on insertion into the frame 2 and are temporarily deformed radially inward.

Fig. 8 zeigt einen Teil des Segmentes 4 gemäß der Verbindung in Fig. 6. Die Rastöse 7 zeigt den sich in Umfangsrichtung erstreckenden rechteckförmigen Schlitz 7a, der jeweils an die Abmessungen der entsprechenden Rastnase 5 angepasst ist. Fig. 8 shows a part of the segment 4 according to the connection in FIG Fig. 6 , The latching eye 7 shows the circumferentially extending rectangular slot 7 a, which is adapted in each case to the dimensions of the corresponding locking lug 5.

Fig. 9 zeigt einen Schnitt entlang der Linie IX-IX in Fig. 3, d: h. durch ein Ringnutsegment 6, welches den unteren Teil des Querschnittes des Segmentes 4 aufnimmt und in beiden radialen Richtungen (nach innen und nach außen) sowie in einer axialen Richtung fixiert. Wie in den vorangegangenen Figuren, insbesondere Fig. 3 dargestellt, sind mehrere Ringnutsegmente 6, vorzugsweise drei für ein Segment 4 vorgesehen. Damit ist das Segment 4 - und ebenso die anderen Segmente - gegenüber der Zarge 2 fixiert und gegen Herausfallen gesichert. Fig. 9 shows a section along the line IX-IX in Fig. 3 , d: h. by a Ringnutsegment 6, which receives the lower part of the cross section of the segment 4 and fixed in both radial directions (inwards and outwards) and in an axial direction. As in the previous figures, in particular Fig. 3 shown, a plurality of Ringnutsegmente 6, preferably three for a segment 4 are provided. Thus, the segment 4 - and also the other segments - fixed relative to the frame 2 and secured against falling out.

Fig. 10 zeigt die Zarge 2 mit dem Querschnitt der Ringnutsegmente 6, zwischen denen eine Rastnase 5 angeordnet ist. Fig. 10 shows the frame 2 with the cross section of the Ringnutsegmente 6, between which a latching lug 5 is arranged.

Fig.11 zeigt einen Teil des Segmentes 4 mit Rastöse 7. Figure 11 shows a part of the segment 4 with locking eye. 7

In den vorstehend erläuterten Figuren sind die flexiblen Dichtelemente bzw. Borsten der Bürstendichtung der Einfachheit halber weggelassen. Tatsächlich sind Borsten an den Segmenten befestigt, die somit als Halterung für die Borsten dienen, welche die Abdichtung des Lüfters gegenüber der Zarge bewirken.In the figures explained above, the flexible sealing elements or bristles of the brush seal have been omitted for the sake of simplicity. In fact, bristles are attached to the segments, which thus serve as a support for the bristles, which cause the sealing of the fan relative to the frame.
