Description
Im serienmäßigen Zustand lassen Stahlblechkarosserien von Kraft fahrzeugen gerade unter folgenden Aspekten den Wunsch nach höherer Stabilität aufkommen:In standard condition, sheet steel bodies leave their strength vehicles, especially in the following aspects, the desire for higher Stability arises:
- a) Verbesserung des Fahrverhaltens durch eine genauere und stabilere Radführunga) Improve driving behavior through a more accurate and more stable wheel guidance
- Folgerung:Conclusion:
- Anzustreben ist eine Erhöhung der Steifigkeit der Karosseriestruktur, die die Radaufhängungsbauteile miteinander verbinde.The aim is to increase the rigidity of the Body structure that the suspension components connect with each other.
-
b) Erhöhung der Crashsicherheit mit den Schwerpunkten:
- - geringeres Verletzungsrisiko des Fahrers durch ein stabilere Fahrgastzelle
- - geringere Instandsetzungskosten infolge der erhöhten Widerstandsfähigkeit der Karosserie- Rahmenstruktur gegen Verziehen.
- - Less risk of injury to the driver through a more stable passenger cell
- - Lower repair costs due to the increased resistance of the body frame structure to warping.
- Folgerung:Conclusion:
- Die Auslegung von Fahrgastzellen erfolgt zur Zeit hauptsächlich unter dem Gesichtspunkt einer hohen Steifigkeit bezüglich Kraftwirkungen in Fahrzeug längsrichtung.Passenger cells are currently being designed mainly from a high point of view Stiffness with regard to the effects of forces in the vehicle longitudinal direction.
- Anzustreben ist daher eine Erhöhung der Steifigkeit der Fahrgastzellenflanken im Hinblick auf Kraftein wirkungen in Fahrzeugquerrichtung.The aim should therefore be to increase the rigidity of the passenger compartment flanks in terms of force cross-vehicle effects.
Es ist bekannt, daß Kraftfahrzeugkarosserien für bestimmte Anfor derungen durch den lösbaren oder unlösbaren Einbau von eigenstän digen Bauteilen (z. B. einzelnen Rohren, Rohrkonstruktionen, Platten, Blechen etc.) entsprechend besonderen Anforderungen verstärkt wer den. Ferner ist es bekannt, eigenständige Bauteile, bestehend aus fa serverstärkten Verbundmaterialdeckschichten, einer abstandhaltenden Zwischenschicht mit wabenähnlicher Struktur und Klebefilm (für die Deckschichten sind auch Metallbleche üblich) herzustellen, die als Sandwichbauteile bezeichnet werden.It is known that motor vehicle bodies for certain requirements changes due to the detachable or non-detachable installation of your own components (e.g. individual pipes, pipe structures, plates, Sheet metal etc.) according to special requirements the. Furthermore, it is known to have independent components consisting of fa server-strengthened composite cover layers, a spacer Interlayer with honeycomb structure and adhesive film (for the Cover layers are also common to produce sheet metal, which as Sandwich components are called.
Für die nachträgliche Verstärkung von Fahrzeugkarosserien durch die Verwendung eigenständiger Bauteile ergibt sich aufgrund der fehlenden Fähigkeit dieser Bauteile, sich dem Karosserieblechver lauf genau anzupassen der Nachteil eines erhöhten Platzbedarfs. Zudem ist für sie, mit Ausnahme von eigenständigen Sandwichbautei len, ein bezüglich der Steifigkeit deutlich höheres spezifisches Gewicht kennzeichnend.For the subsequent reinforcement of vehicle bodies by the use of independent components results from the lack of ability of these components to join the body panel adapt exactly the disadvantage of an increased space requirement. In addition, for them, with the exception of independent sandwich construction len, a significantly higher specific in terms of rigidity Characteristic weight.
Hinsichtlich eigenständiger Sandwichbauteile mit Deckschichten aus dem gleichen Material, wie in dem hier beschriebenen Verstärkungs verfahren verwendeten, ist der Nachteil des höheren auf die Stei figkeit bezogenen Gewichtes zwar etwas geringer, dafür ergeben sich für diese eigenständigen Bauteile erhebliche Probleme bezüglich einer stabilen und kraftübertragenden Verbindung mit dem Karos serieblech, sowie die o.a. Nachteile in Bezug auf den Platzbedarf durch die ihnen ebenfalls fehlende Fähigkeit, sich dem Karosserie blechverlauf genau anzupassen.With regard to independent sandwich components with outer layers the same material as in the reinforcement described here The method used is the disadvantage of the higher on the Stei weight-related weight a little lower, but result for these standalone components significant problems a stable and force-transmitting connection with the diamond series sheet, as well as the above Disadvantages in terms of space requirements due to their lack of ability to adapt to the body to adjust the sheet profile exactly.
Der in Anspruch 1 angegebenen Erfindung liegt das Problem zugrun de, den auf die Steifigkeit bezogenen spezifischen Platzbedarf von nachträglichen Karosserieverstärkungen zu verringern, sowie die auf die Steifigkeit bezogene Gewichtszunahme zu optimieren.The invention specified in claim 1 is based on the problem de, the specific space requirement of to reduce subsequent body reinforcements, as well as on to optimize the stiffness-related weight gain.
Die mit der Erfindung erzielten Vorteile liegen insbesondere darin begründet, daß zum einen Materialien mit sehr geringem spezifischen Gewicht (Gewicht/Volumen) verwendet werden und zum zweiten die aufgebrachte Verstärkungsstruktur zusammen mit dem Karosserie blech, auf dem sie aufgebracht wird, zu einem Gesamtbauteil in Sandwichbauweise wird und auch als solches wirkt. Die durch die Erfindung genutzte Eigenschaft solcher Sandwichbauteile ist die, daß ihr Widerstandsmoment gegen Biegung überproportional von dem Abstand ihrer Deckschichten abhängt, nicht aber von der eigenen Biegesteifigkeit der Zwischenschicht. Dadurch ist es möglich für sich biegeflexible Zwischenschichten sehr geringen spezifischen Gewichtes zu verwenden, die allein die Fähigkeit besitzen müssen im späteren Gesamtverbund den vorgegebenen Abstand der Deckschichten (bei der vorliegenden Erfindung sind dies die Verbundmaterialdeck schicht aus harzgetränkten Gewebematten und das Karosserieblech) unter Belastung sicherzustellen. The advantages achieved with the invention are in particular justifies that on the one hand materials with very low specific Weight (weight / volume) and secondly the applied reinforcement structure together with the body sheet on which it is applied to an overall component in Sandwich construction is and also acts as such. The through the The property of such sandwich components used according to the invention is that that their moment of resistance to bending is disproportionate to that Distance of their cover layers depends, but not on their own Bending stiffness of the intermediate layer. This makes it possible for flexible intermediate layers of very low specific To use weight, which alone must have the ability in the later overall composite the specified distance of the cover layers (In the present invention, these are the composite material decks layer of resin-impregnated fabric mats and the body panel) ensure under load.
Im Sinne der Problemstellung der Erfindung bezüglich geringstem Gewichtes bei hoher Steifigkeit eignen sich als abstandhaltende Zwischenschicht insbesondere Hohlkörpermaterialien mit einer auf das Gewicht bezogenen hohen Druckfestigkeit in mindestens einer Richtung (z. B. wabenähnliche Strukturen, Hartschäume etc.).In terms of the problem of the invention with regard to the least Weight with high rigidity are suitable as spacers Intermediate layer, in particular hollow body materials with a the weight related high compressive strength in at least one Direction (e.g. honeycomb-like structures, rigid foams etc.).
Die daraus folgenden Vorteile der Erfindung stellen sich wie folgt dar:The resulting advantages of the invention are as follows represents:
- - ein erheblicher auf die Steifigkeit bezogener Gewichtsvorteil gegenüber bekannten Karosserieverstärkungen zum einen aufgrund der speziellen Eigenschaften der erstellten Gesamtstruktur (Sandwichbauteil), zum zweiten aufgrund der Tatsache, daß das vorhandene Karosserieblech in die Verstärkungsstruktur mitein bezogen wird,- A considerable weight advantage related to the rigidity compared to known body reinforcements on the one hand the special properties of the forest created (Sandwich component), secondly due to the fact that the existing body panel in the reinforcement structure is related,
- - ein auf die Steifigkeit bezogener deutlich geringerer Platzbe darf gegenüber bekannten Karosserieverstärkungen aufgrund der speziellen Eigenschaften der erstellten Gesamtstruktur (Sand wichbauteil).- A significantly smaller space related to the rigidity compared to known body reinforcements due to the special properties of the created overall structure (sand important component).
Mit der zusätzlichen Eigenschaft der beschriebenen Verstärkungs struktur, sich dem Karosserieblechverlauf genau anzupassen, ergeben sich die weiteren Vorteile:With the additional property of the reinforcement described structure to adapt exactly to the bodywork, there are further advantages:
- - die Möglichkeit, eine wirksame Verstärkung der Karosserie auch an solchen Stellen zu erreichen, an denen es mit den bekannten Mit teln aufgrund des geringen zur Verfügung stehenden Platzes nicht möglich ist,- The possibility of effective reinforcement of the body also to reach places where it is known with the Mit due to the limited space available is possible,
- - die bestehende Einbauposition vorhandener Bauteile kann fast immer beibehalten werden,da deren Raumbedarf durch den der Ver stärkung - im Gegensatz zu den bekannten Verfahren - nur in den seltensten Fällen beeinträchtigt wird,- The existing installation position of existing components can almost always be maintained, because their space requirement by the Ver strengthening - in contrast to the known methods - only in the rarely is affected,
- - die Möglichkeit, Bereiche der Karosserie mit einer deutlich höheren Wirkung, als mit bekannten Verfahren punktuell zu verstärken.- the ability to clearly identify areas of the body higher effect than selectively with known methods reinforce.
Betreffen alle beschriebenen Vorteile der Erfindung die Ziel setzung nach Punkt a) der "grundlegenden Betrachtung" gleicher maßen, so sind speziell die zuletzt aufgezählten drei weiteren Vorteile die Grundlage für eine Anwendung gemäß der unter Punkt b) der "grundlegenden Betrachtung" genannte Zielsetzung der Flanken steifigkeitserhöhung (z. B. Verstärkungen im knapp bemessenen Türinnenraum). All of the described advantages of the invention relate to the goal according to point a) of the "basic consideration" of the same dimensions, so are the last three listed specifically Advantages the basis for an application according to the under point b) the objective of the flanks called "basic consideration" increase in stiffness (e.g. reinforcements in the tight Door interior).
Außer Kraftfahrzeugkarosserien lassen sich mit der Erfindung in gleicher Weise auch beliebige andere Bauteile verstärken. Voraus setzung ist allein, daß das Material des zu verstärkenden Bauteils sich als einseitige Deckschicht für die entstehende Sandwich- Struktur eignet.In addition to motor vehicle bodies, the invention can be used in reinforce any other components in the same way. Advance The only setting is that the material of the component to be reinforced itself as a one-sided cover layer for the resulting sandwich Structure.
Anhand der folgenden Systemzeichnungen werden zwei prinzipielle Möglichkeiten des Aufbaus der Karosserieverstärkung erläutert:Based on the following system drawings, two basic ones are shown Possibilities of building the body reinforcement explained:
Fig. 1 perspektivische Darstellung eines Ausschnitts aus einer Verstärkungsstruktur mit einer Klebe filmlage; Fig. 1 perspective view of a section of a reinforcing structure with an adhesive film layer;
Fig. 2 Schnitt durch einen Ausschnitt einer Verstär kungsstruktur mit einer Klebefilmlage; Fig. 2 section through a section of a reinforcement structure with an adhesive film layer;
Fig. 3 Schnitt durch einen Ausschnitt einer Verstär kungsstruktur mit zwei Klebefilmlagen. Fig. 3 section through a section of a reinforcing structure with two layers of adhesive film.
Mit diesem Begriff werden Gewebematten aus künstlichen Fasern (z. B.: Kohlenstoff-, Glas- o. Aramidfasern) bezeichnet, die mit dem die Matrix des späteren Verbundwerkstoffs bildenden Harzsystem in der Weise getränkt sind, daß die im Verarbeitungszustand flexible, leicht klebrige Matte nach dem Aushärten einen vollständigen Verbundwerkstoff darstellt.With this term, tissue mats are made of artificial fibers (e.g .: carbon, glass or aramid fibers), which with the the matrix of the later composite material forming resin system in are soaked that the flexible, slightly sticky mat after curing a full one Composite represents.
Als Harzsysteme werden Kunstharze (z. B.: Epoxidharz) verwendet. Die Aushärtung erfolgt unter Wärme. (Fachausdruck: "Prepreg"-Verbundwerkstoffsystem).Synthetic resins (e.g. epoxy resin) are used as resin systems. The curing takes place under heat. (Technical term: "prepreg" composite system).
Es handelt sich hierbei um ein in Form flexibler oder hochflexi bler Platten beliebiger Stärke angeliefertes Material mit einer Struktur aus nebeneinander angeordneten Waben sehr dünner Wand stärke, deren Orientierung senkrecht zur Plattenausdehnung ist. Für die Wabengestaltung werden verschiedene Raumkörperformen gewählt (z. B.: Sechseck, Viereck, Zylinder, Freiformkörper).It is a flexible or highly flexible material of any thickness supplied with a Structure made of very thin wall honeycombs arranged side by side thickness whose orientation is perpendicular to the plate expansion. Different spatial shapes are used for the honeycomb design selected (e.g. hexagon, square, cylinder, free-form body).
Als Werkstoffe werden Leichtmetalle (z. B.: Aluminium) oder Nichtmetalle (z. B.: Nomex) verwendet (Fachausdruck: "Honeycomb"). Als Zwischenschicht können auch Platten aus Hartschaum verwendet werden.Light metals (e.g. aluminum) or Non-metals (e.g. Nomex) are used (technical term: "Honeycomb"). Sheets of hard foam can also be used as an intermediate layer will.
Bezeichnet wird hiermit ein in Folienform vorliegender Klebstoff. Der Klebstoff basiert auf Kunstharzen (z. B.: Epoxydharz). Die Aushärtung erfolgt unter Wärme. This is used to refer to an adhesive in foil form. The adhesive is based on synthetic resins (e.g. epoxy resin). The curing takes place under heat.
Mit dem blanken und durch entsprechende Verfahren aufgerauhten Karosserieblech (4), welches zu verstärken ist, wird die die Deck schichten (Karosserieblech (4) und Prepreg-Verbundmaterialdeck schicht (1)) auf Abstand haltende Zwischenschicht (2) - in den Zeichnungen handelt es sich um Honeycomb - mittels des Klebefilms (3) verbunden.With naked and roughened by appropriate methods body panel (4) which is to be amplified, which is the cover layer (body panel (4) and prepreg composite material top layer (1)) holding at a distance from the intermediate layer (2) - in the drawings is around Honeycomb - connected by means of the adhesive film ( 3 ).
Die Deckschicht aus Prepreg-Verbundmaterial geht infolge der Klebeeigenschaften des enthaltenden Harzes wiederum eine feste Verbindung mit der Zwischenschicht ein.The top layer of prepreg composite material is due to the Adhesive properties of the resin contained in turn a firm Connection with the intermediate layer.
Der Aufbau dieser Ausführung unterscheidet sich nur dadurch von der in Position 1 beschriebenen Variante, daß zur Unterstützung der Klebekräfte der Verbundmaterialdeckschicht (1) zwischen dieser und der Zwischenschicht (2) eine zusätzliche Klebefilmlage (3) einge baut wird.The structure of this embodiment differs only from the variant described in position 1 in that an additional layer of adhesive film ( 3 ) is built in to support the adhesive forces of the composite material cover layer ( 1 ) between this and the intermediate layer ( 2 ).
Dies wird an solchen Stellen vorgenommen, an denen zu erwarten ist, daß infolge der Belastungen im Einsatz das Bestreben der Gewebela gendeckschicht, sich von der Zwischenschicht abzulösen, die der Ge webeschicht eigenen Klebekräfte überfordern könnte.This is done in places where it is expected that as a result of the stresses in use the effort of the tissue la cover layer to separate from the intermediate layer that the Ge webeschicht could overwhelm its own adhesive forces.
Nachdem die einzelnen Materialschichten formschlüssig auf das zu verstärkende Karosserieblech entsprechend der vorangegangenen Beschreibung aufgebracht wurden, erfolgt die Aushärtung des(der) Klebefilmlage(n) und der Verbundmaterialdeckschicht in der Weise, daß zum einen die Gesamtstruktur auf die zur Aushärtung notwendige Temperatur erwärmt wird, zum zweiten durch Druck auf die Deckschichten ein lückenloser Kontakt der Bestandteile der Ver stärkungsstruktur während des Aushärtens sichergestellt wird.After the individual layers of material form-fitting towards the reinforcing body panel according to the previous one Description has been applied, the curing of the Adhesive film layer (s) and the composite material top layer in the Way that on the one hand the overall structure to cure necessary temperature is heated, secondly by pressing on the Cover layers a gapless contact of the components of the ver strengthening structure is ensured during curing.
