Abstract

The e.g. vehicle assembly consists of two or more especially composite material components. These are bonded together at a flat interface. The distance between the opposite faces of the composite components at the interface is maintained by a series of small projections (5) at intervals along the recess. The thin space surrounding these projections is filled up with adhesive material

Description

Die Erfindung betrifft Klebverbindungen zwischen zwei Bautei­ len mit den Merkmalen des Oberbegriffes des Anspruches 1 oder mit den Merkmalen des Oberbegriffes des Anspruches 9.The invention relates to adhesive bonds between two components len with the features of the preamble of claim 1 or with the features of the preamble of claim 9.

Die zwischen zwei Bauteilen, insbesondere zwischen zwei Fa­ serverbundkunststoffteilen, mit Hilfe einer Klebeverbindung erreichbare Festigkeit hängt von der Breite und von der Aus­ gestaltung des zwischen den Bauteilen bestehenden Klebespal­ tes ab. Je enger der Klebespalt und je gleichmäßiger dieser ausgebildet ist, desto höhere Festigkeitswerte kann die Kle­ beverbindung aufweisen. Um eine hohe Gleichmäßigkeit der Spaltbreite zwischen den sich gegenüberliegenden Klebeflächen der zu verklebenden Bauteile bei einer kleinen Spaltbreite, d. h. bei einem engen Klebespalt, auch bei großen Klebeflächen mit relativ kompliziertem Verlauf sicherzustellen, ist bis­ lang ein hoher Vorrichtungsaufwand erforderlich.The between two components, in particular between two Fa plastic composite parts, with the help of an adhesive connection achievable strength depends on the width and the Aus design of the adhesive gap between the components tes off. The narrower the adhesive gap and the more uniform it is is formed, the higher strength values the adhesive can Have connection. To ensure a high level of uniformity Gap width between the opposite adhesive surfaces the components to be bonded with a small gap width, d. H. with a narrow adhesive gap, even with large adhesive surfaces to ensure with a relatively complicated course is up to long required a high expenditure on devices.

Aus der DE-OS 29 32 027 ist eine Klebeverbindung zwischen Blechteilen bekannt, bei der an einer der Klebeflächen, die sich im Klebespalt gegenüberliegen, eine hervorstehende Rippe vorgesehen ist, die im Bereich der Klebefläche zwei Teilflä­ chen voneinander abtrennt und eine bestimmte Spaltbreite zwi­ schen den Klebeflächen der Bauteile definiert. Bei dieser be­ kannten Klebverbindung sollen mit Hilfe der Rippe zwei ebene geradlinige Klebebereiche auf einen bestimmten Abstand gehal­ ten werden. Wenn die miteinander zu verbindenden Bauteile im Bereich ihrer Klebverbindung kompliziert ausgestaltet sind, ist die Anbringung einer derartigen Rippe nur sehr aufwendig oder gar nicht realisierbar.From DE-OS 29 32 027 an adhesive connection between Sheet metal parts known in which on one of the adhesive surfaces facing each other in the adhesive gap, a protruding rib  It is provided that two sub-areas in the area of the adhesive surface chen separated from each other and a certain gap width between between the adhesive surfaces of the components. With this be Known adhesive connection should be two levels with the help of the rib straight adhesive areas at a certain distance be. If the components to be connected in the Area of their adhesive connection are complicated, the attachment of such a rib is only very complex or not feasible at all.

Die vorliegende Erfindung beschäftigt sich mit dem Problem, bei einer Klebverbindung der eingangs genannten Art mit kon­ struktiv einfachen Maßnahmen, einen gleichmäßig verlaufenden und engen Klebespalt zu gewährleisten.The present invention addresses the problem in an adhesive connection of the type mentioned with con structurally simple measures, a smoothly running and to ensure a narrow adhesive gap.

Dieses Problem wird mit einer Klebverbindung mit den Merkma­ len des Anspruches 1 gelöst.This problem is solved with an adhesive connection with the Merkma len of claim 1 solved.

Die Erfindung beruht hierbei auf dem allgemeinen Gedanken, daß zur Erzielung einer definierten Spaltbreite entlang der ganzen Länge des Klebespaltes nur einzelne Distanzelemente vorhanden sein müssen, die über die ganze Klebefläche des Klebespalts verteilt angeordnet sind. Außerdem kann die Höhe der etwa punktförmigen, als Noppen ausgebildeten Distanzele­ mente relativ genau eingehalten werden, wodurch sich ein be­ sonders gleichmäßiger Klebespalt ergibt. Als Folge davon kann eine extrem zuverlässige und hochbelastbare Klebverbindung erzielt werden. The invention is based on the general idea that to achieve a defined gap width along the the entire length of the adhesive gap only individual spacer elements must be present, which over the entire adhesive surface of the Adhesive gap are arranged distributed. In addition, the height the approximately punctiform spacer elements designed as knobs elements are observed relatively precisely, which results in a be results in a particularly even adhesive gap. As a result, it can an extremely reliable and heavy-duty adhesive connection be achieved.  

Üblicherweise wird für die Herstellung einer Klebverbindung ein relativ langsam aushärtender Klebstoff verwendet, wobei zur Unterstützung oder Beschleunigung des Aushärtvorganges oftmals auch eine Wärmebehandlung erforderlich ist. Damit die mit Klebstoff versehenen zusammengefügten Bauteile transport­ fähig sind und damit der Klebstoff auch in der zwischen den Bauteilen vorgesehenen Relativlage aushärtet, kann die erfin­ dungsgemäße Klebverbindung mit den Merkmalen des Anspruches 2 weitergebildet sein. Dabei erfolgt die Positionierung bzw. die Fixierung der Bauteile zueinander im Bereich der Distan­ zelemente und somit genau an den Stellen, die für die Erzie­ lung des gleichmäßigen Klebespaltes verantwortlich sind. Gleichzeitig können mit den geeigneten Befestigungsmitteln die Bauteile gegeneinander vorgespannt werden, was ebenfalls zur Erzielung einer hochwertigen Klebeverbindung hilfreich ist. Dabei erfolgt durch die Noppen genau an den Stellen eine Abstützung zwischen den Bauteilen, an denen die Vorspannkräf­ te eingeleitet werden, so daß keine Biegespannungen auftreten können, die sich negativ auf die Gleichmäßigkeit des Kle­ bespaltes und folglich auf die Festigkeit der Klebverbindung auswirken könnten.Usually used for the production of an adhesive connection used a relatively slow curing adhesive, whereby to support or accelerate the curing process often a heat treatment is required. So that transport assembled components provided with adhesive are capable and therefore the adhesive also in the between the Cures the relative position provided, the inventions inventive adhesive connection with the features of claim 2 be educated. The positioning or the fixation of the components to each other in the area of the Distan elements and thus exactly in the places that are necessary for the education the uniform adhesive gap are responsible. At the same time, with the appropriate fasteners the components are biased against each other, which is also helpful to achieve a high quality adhesive bond is. The knobs create one at exactly the points Support between the components on which the preload te be initiated so that no bending stresses occur can adversely affect the uniformity of the Kle and therefore on the strength of the adhesive bond could impact.

Das Problem wird auch mit einer Klebverbindung mit den Merk­ malen des Anspruches 9 gelöst. Hierbei werden separate Di­ stanzelemente im Spaltbereich zwischen den miteinander zu verbindenden Bauteilen angeordnet, um einen definierten Spal­ tabstand zu gewährleisten. Die dazu verwendeten Distanzele­ mente sind vorzugsweise flächig ausgebildet und haben eine Scheiben- oder Plattenform.The problem is also solved with an adhesive connection with the Merk paint the claim 9 solved. Here separate Di punching elements in the gap area between them connecting components arranged to a defined gap to ensure tabstand. The distance elements used for this  elements are preferably flat and have a Disc or plate shape.

Bei einer besonders bevorzugten Ausführungsform der erfin­ dungsgemäßen Klebverbindung mit den Merkmalen des Anspruches 11 weisen benachbarte Distanzelemente einen Abstand zwischen 50 bis 200 mm auf. Dabei richtet sich der Abstand nach der im jeweiligen Bereich des Klebespaltes vorliegenden Kontur und Eigensteifigkeit des Bauteils.In a particularly preferred embodiment of the invention inventive adhesive connection with the features of the claim 11 have adjacent spacing elements a distance between 50 to 200 mm. The distance depends on the im contour of the respective area of the adhesive gap and Intrinsic rigidity of the component.

Weitere wichtige Merkmale und Vorteile ergeben sich aus den Unteransprüchen und aus der nachfolgenden Beschreibung eines Ausführungsbeispieles. Es zeigen, jeweils schematischOther important features and advantages result from the Subclaims and from the following description of a Embodiment. It shows, each schematically

Fig. 8 eine Schnittansicht wie in Fig. 7, jedoch mit einer Noppe, die ein Durchgangsloch aufweist. Fig. 8 is a sectional view as in Fig. 7, but with a knob that has a through hole.

Entsprechend Fig. 1 soll ein erstes Bauteil 1 entsprechend den Pfeilen a auf ein zweites Bauteil 2 aufgesetzt werden, um mit einer erfindungsgemäßen Klebverbindung zwischen einem An­ schlußflansch 3 am ersten Bauteil 1 und einem Anschlußflansch 4 am zweiten Bauteil 2 miteinander verbunden zu werden.According to Fig. 1 is to be fitted according to the arrows A on a second member 2, a first component 1 to 3 can be connected with an inventive adhesive bond between an end flange on the first component 1 and a connecting flange 4 on the second component 2 to each other.

Auf der Oberseite des Anschlußflansches 4 des zweiten Bautei­ les 2 sind mehrere, im Vergleich zur Klebefläche punktförmige Erhebungen oder Noppen 5 angeformt, die beim Aufsetzen des ersten Bauteiles 1 an diesem bzw. an dessen Anschlußflansch 3 zur Anlage kommen. Die Noppen 5 weisen jeweils eine vorbe­ stimmte Höhe auf und definieren dadurch die Breite des sich zwischen den Anschlußflanschen 3 und 4 ausbildenden Kle­ bespaltes. Durch eine geeignete Beabstandung der Noppen 5 entlang des Anschlußflansches 4 wird ein Klebespalt erzielt, dessen Spaltbreite über die gesamte Spaltlänge gleichmäßig verläuft, d. h. im wesentlichen konstant bleibt. Obwohl im Ausführungsbeispiel eine relativ einfache Form bzw. Kontur für die Anschlußflansche 3 und 4 gezeigt ist, ermöglicht die erfindungsgemäße Klebverbindung, einen gleichmäßigen und en­ gen Spalt auch bei komplizierten Konturen und großflächigen Klebverbindungen zu erzielen.On the top of the connecting flange 4 of the second component 2 , several, in comparison to the adhesive surface punctiform elevations or knobs 5 are formed, which come to rest when the first component 1 is placed on this or on its connecting flange 3 . The knobs 5 each have a predetermined height and thereby define the width of the gap formed between the connecting flanges 3 and 4 adhesive gap. By means of a suitable spacing of the knobs 5 along the connecting flange 4 , an adhesive gap is achieved, the gap width of which runs uniformly over the entire gap length, ie remains essentially constant. Although a relatively simple shape or contour for the connecting flanges 3 and 4 is shown in the exemplary embodiment, the adhesive connection according to the invention enables a uniform and narrow gap to be achieved even with complicated contours and large-area adhesive connections.

Vor dem Aufsetzen des ersten Bauteiles 1 auf das zweite Bau­ teil 2 wird Klebstoff auf den Anschlußflansch 3 und/oder auf den Anschlußflansch 4 aufgetragen, das heißt auf die vorgese­ hene Klebefläche der Klebverbindung.Before the first component 1 is placed on the second construction part 2 , adhesive is applied to the connecting flange 3 and / or to the connecting flange 4 , that is to say to the gluing surface of the adhesive connection that is provided.

Aus Fig. 2 ist zu entnehmen, daß die Bauteile 1 und 2 soweit aufeinander gedrückt werden, bis die Noppen 5 im Spaltbereich am ersten Bauteil 1 bzw. an dessen Anschlußflansch 3 zur An­ lage kommen. Dabei wird die durch die Noppenhöhe vorbestimmte Spaltbreite erreicht. Gleichzeitig verteilt sich ein aufge­ tragener Klebstoff 12 relativ gleichmäßig im Bereich der Klebverbindung, insbesondere umschließt er die Noppen 5 und integriert diese vollständig in der Klebverbindung. Dieser Einschluß der Noppen 5 im Klebstoff 12 bewirkt zusätzlich ei­ nen Formschluß, der zur Erhöhung der Festigkeit der Klebver­ bindung beitragen kann.From Fig. 2 it can be seen that the components 1 and 2 are pressed together until the knobs 5 in the gap area on the first component 1 or on its connecting flange 3 come to position. The gap width predetermined by the nub height is reached. At the same time, an applied adhesive 12 is distributed relatively evenly in the area of the adhesive connection, in particular it encloses the knobs 5 and integrates them completely in the adhesive connection. This inclusion of the knobs 5 in the adhesive 12 additionally causes a positive connection, which can contribute to increasing the strength of the adhesive bond.

Entsprechend Fig. 3 kann zur Erzielung einer Anpreßkraft zwi­ schen den beiden Bauteilen 1 und 2 bzw. zwischen ihren An­ schlußflanschen 3 und 4 eine Schraube 6 als Befestigungsmit­ tel verwendet werden. Dabei durchdringt die Schraube 6 den Flansch 3 und dringt in die Noppe 5 im Anschlußflansch 4 ein. Dabei kann eine Durchgangsbohrung für die Schraube 6 im An­ schlußflansch 3 vorgesehen sein oder die Schraube 6 wird ein­ gebracht, wenn die Anschlußflansche 3 und 4 in geeignetem Ma­ ße gegeneinander vorgespannt sind.According to FIG. 3 can be used to achieve a contact pressure Zvi rule the two components 1 and 2 and between their on schlußflanschen 3 and 4, a screw 6 to be used as Befestigungsmit tel. The screw 6 penetrates the flange 3 and penetrates into the knob 5 in the connecting flange 4 . Here, a through hole for the screw 6 in the connection flange 3 can be provided or the screw 6 is brought in when the connecting flanges 3 and 4 are biased against each other in a suitable dimension.

Entsprechend Fig. 4 kann zur Fixierung der miteinander durch die Klebverbindung zu verbindenden Bauteile 1 und 2 auch ein Niethefter 7 verwendet werden, der beide Bauteile 1 und 2 bzw. deren Flansche 3 und 4 im Bereich einer Noppe 5 durch­ dringt. Auf diese Weise können Zugkräfte aufgebracht werden, die sich vorteilhafterweise an den Außenseiten der Anschluß­ flansche 3 und 4 abstützen.According to FIG. 4, a rivet stitcher 7 can also be used to fix the components 1 and 2 to be connected to one another by the adhesive connection, which rivets through both components 1 and 2 or their flanges 3 and 4 in the region of a knob 5 . In this way, tensile forces can be applied, which are advantageously supported on the outer sides of the connection flanges 3 and 4 .

In gleicher Weise arbeitet entsprechend Fig. 5 eine Niet 8, die zur Befestigung der Bauteile 1 und 2 verwendet wird, wo­ bei auch die Niet 8 die Noppe 5 durchdringt.In the same way, according to FIG. 5, a rivet 8 is used , which is used for fastening the components 1 and 2 , where the rivet 8 also penetrates the knob 5 .

Die Anbringung der gezeigten Befestigungselemente Schraube 6, Niethefter 7, Niet 8 jeweils im Bereich einer Noppe 5 ist be­ sonders zweckmäßig, da auf diese Weise keine Biegebelastungen auf die Anschlußflansche 3 und 4 ausgeübt werden. Dies hat zur Folge, daß die Einleitung der Vorspannkräfte keinen Ein­ fluß auf die Breite des Klebespaltes hat. Die Befestigungs­ mittel 6, 7, 8 dienen hauptsächlich der Fixierung während des Aushärtvorganges der Klebverbindung. Außerdem bewirken sie eine zusätzliche Erhöhung der Festigkeit der Klebverbindung. Falls die beispielhaft aufgeführten Befestigungsmittel jedoch die Außenkontur der Bauteile 1 und 2 in ästhetischer oder auch in funktioneller Hinsicht stören, können sie nach dem Aushärten des Klebestoffes 12, insbesondere durch Abschlei­ fen, wieder entfernt werden.The attachment of the fasteners shown screw 6 , rivet stapler 7 , rivet 8 each in the area of a knob 5 is particularly useful, since in this way no bending loads are exerted on the connecting flanges 3 and 4 . This has the consequence that the introduction of the biasing forces has no influence on the width of the adhesive gap. The fastening means 6 , 7 , 8 are mainly used for fixing during the curing process of the adhesive connection. They also cause an additional increase in the strength of the adhesive bond. However, if the fasteners listed by way of example interfere with the outer contour of components 1 and 2 from an aesthetic or functional point of view, they can be removed again after the adhesive 12 has hardened, in particular by grinding.

Anstelle der in den Fig. 3 bis 5 gezeigten Befestigungsmittel 6, 7, 8 können zum Aufbringen der Anpreßkraft auch von außen auf die Anschlußflansche 3 und 4 andrückende Druckleisten 9 verwendet werden. Nach dem Aushärten des Klebstoffes können diese dann ohne Spuren auf den Bauteilen 1 und 2 zu hinter­ lassen, entfernt werden.Instead of the fastening means 6 , 7 , 8 shown in FIGS . 3 to 5, pressure strips 9 which press on the connecting flanges 3 and 4 from outside can also be used to apply the contact pressure. After the adhesive has hardened, it can then be removed without leaving any traces on components 1 and 2 .

Entsprechend Fig. 7 kann zur besseren Anbringung der Befesti­ gungsmittel 6, 7, 8 eine zentrische Vertiefung 10 in der Nop­ pe 5 vorgesehen sein, mit deren Hilfe das jeweilige Befesti­ gungsmittel, z. B. eine Niet 8, zentriert werden kann.According to Fig. 7 can be used for better attachment of its mountings supply means 6, 7, 8 has a central recess 10 in the pe Nop 5 can be provided by means of which the respective Fixed To supply medium such. B. a rivet 8 can be centered.

Ein anderes Mittel zur Zentrierung des jeweiligen Befesti­ gungsmittels 6, 7, 8 ist entsprechend Fig. 8 ein Durchgangs­ loch 11, das zentrisch in der Noppe 5 vorgesehen ist. Das Durchgangsloch 11 dient beispielsweise zum Einstecken einer Niet 8, wobei auf einfache Weise gewährleistet ist, daß die von der Niet 8 bewirkte Anpreßkraft zentrisch und somit be­ sonders gleichmäßig auf die Noppe 5 übertragen wird.Another means for centering the respective fastening means 6 , 7 , 8 is, according to FIG. 8, a through hole 11 which is provided centrally in the knob 5 . The through hole 11 is used, for example, for inserting a rivet 8 , which ensures in a simple manner that the contact pressure caused by the rivet 8 is transmitted centrally and thus be particularly uniformly onto the knob 5 .
