Fig. 2 zeigt in einer perspektivischen, schematischen Ansicht eine teilweise fertiggestellte FahrzeugkarosSerie, die als Plattform für ein darauf aufzubauendes Cabriolet-Fahrzeug dienen kann. Wie man erkennt, fehlen in der Plattform 1 nach Fig. 2 noch tragende Elemente wie A-Säule, B-Säule und unterer Schweller, die der Karosserie Stabilität und Schutz gegen Seitenaufprall geben.Fig. 2 shows a perspective, schematic view of a partially completed vehicle body series, which can serve as a platform for a convertible vehicle to be built thereon. As can be seen, the platform 1 according to FIG. 2 still lacks supporting elements such as the A-pillar, B-pillar and lower sill, which give the body stability and protection against side impact.
Herkömmlicherweise werden Seitenwandrahmen von Fahrzeugen aus einem großen gepreßten Blechteil durch z.B. Tiefziehen hergestellt. Hierzu werden aus großen Blechtafeln mittels die Form fest vorgebenden Preßwerkzeugen Teile erstellt. Eine Anpassung ist nur durch aufwendige Werkzeugänderung bzw. Neuerstellung möglich.Conventionally, side wall frames of vehicles are made from a large pressed sheet metal part by e.g. Thermoforming. For this purpose, parts are created from large metal sheets by means of pressing tools which give the shape. An adjustment is only possible through complex tool changes or new creation.
Die Erfindung bietet die Möglichkeit, speziell für Cabriolet- bzw. Coupe-Fahrzeuge eine integrierte Space- frame-Struktur zu schaffen, die an vorhandene oder zu entwickelnde Plattformen mit oder ohne integriertem Seitenaufprallschutz anpaßbar ist.The invention offers the possibility, especially for convertible or coupe vehicles, of an integrated space To create a frame structure that can be adapted to existing or to be developed platforms with or without integrated side impact protection.
Unter Bezugnahme auf Fig. 1 wird erfindungsgemäß ein Seitenwandmodul bereitgestellt, das eine A-Säule 2, eine B-Säule 4, einen Schweller 6 sowie einen hinteren Längsträger 8 aufweist. Die genannten Komponenten sind vorgefertigte Hohlprofile mit geschlossener Querschnittsform, die durch Innenhochdruckumformung, insbe- sondere Hydroforming, oder im Roll- bzw. Knetverfahren hergestellt sind. Der Schweller 6 ist in diesem Ausführungsbeispiel ein Rollprofil, das durch einen seitlich aufgeschweißten, im Querschnitt in etwa C-förmigen Au- ßenschweller 10 verstärkt ist. Im Gegensatz zu dem Schweller 6 sind A-Säule 2, B-Säule 4 und Längsträger 8 als IHU-Teile (durch Innenhochdruckumformen) hergestellt. Hierbei besteht der Vorteil, daß auch bei Verwendung von kostengünstigem Ausgangsmaterial (durchschnittliche Stahlsorten) aufgrund der Kaltverfestigung des Materials hohe Materialfestigkeiten in den fertigen Teilen erzielt werden können.With reference to FIG. 1, a side wall module is provided according to the invention, which has an A-pillar 2, a B-pillar 4, a sill 6 and a rear side member 8. The components mentioned are prefabricated hollow profiles with a closed cross-sectional shape, which are produced by internal high-pressure forming, in particular hydroforming, or using the rolling or kneading process. In this exemplary embodiment, the sill 6 is a rolling profile which is reinforced by an outer sill 10 which is welded on to the side and is approximately C-shaped in cross section. In contrast to the sill 6, A-pillar 2, B-pillar 4 and side members 8 are manufactured as hydroforming parts (by hydroforming). The advantage here is that even when using inexpensive starting material (average steel grades) high material strengths can be achieved in the finished parts due to the work hardening of the material.
Wie in Fig. 1 angedeutet ist, sind A- und B-Säulen 2, 4 mit ihren unteren Endabschnitten 2a, 4a vollständig durch das Profil des Schwellers 6 hindurchgesteckt, wobei der Schweller zu diesem Zwecke die Endabschnitte 2a, 4a formschlüssig umschließende Aufnahmeoffnungen 12, 14 und 16, 18 aufweist. Fig. 3 zeigt beispielhaft das Querschnittsprofil eines oberen Bereichs der B-Säule 4, während Fig. 4 die Befestigung des hinteren Längsträgers 8 an der B-Säule 4 zeigt. Ebenso wie die A- und B-Säulen ist der hintere Längsträger 8 mit seinem vorderen Endabschnitt 8a vollständig durch die B-Säule 4 hindurchgesteckt und auf diese Weise mit dieser zusammengefügt, wobei die B- Säule zwei Aufnahmeoffnungen 20, 22 aufweist, in die der Längsträger 8 eingesteckt und eingeschweißt ist.As indicated in FIG. 1, the A and B pillars 2, 4 with their lower end sections 2a, 4a are completely inserted through the profile of the rocker 6, the rocker for this purpose receiving openings 12, positively enclosing the end sections 2a, 4a 14 and 16, 18. FIG. 3 shows an example of the cross-sectional profile of an upper region of the B-pillar 4, while FIG. 4 shows the fastening of the rear side member 8 to the B-pillar 4. Just like the A and B pillars, the rear longitudinal member 8 is completely inserted with its front end section 8a through the B pillar 4 and joined together in this way, the B pillar having two receiving openings 20, 22 into which the Side member 8 is inserted and welded.
Sämtliche Aufnahmeoffnungen 12, 14, 16, 18, 20, 22 sind vorzugsweise gelasert, wodurch sich eine hohe Präzision und formschlüssige Passung der einzelnen Teile ergibt, so daß sich eine große Steifigkeit des Seitenwandmoduls und hohe Belastbarkeit in sämtlichen Richtungen ergibt.All receiving openings 12, 14, 16, 18, 20, 22 are preferably lasered, which results in a high precision and form-fitting fit of the individual parts, so that there is great rigidity of the side wall module and high resilience in all directions.
Obwohl die Erfindung bevorzugt vorsieht, daß sämtliche Verbindungen zwischen A- und B-Säulen, Schweller und Längsträger in der erläuterten Weise durch vollständiges Einstecken eines jeweiligen Endabschnitts eines der miteinander zu verbindenden Teile in das andere gebil- det ist, kann auch vorgesehen sein, daß lediglich eine oder einige ausgewählte Verbindungen in der beschriebenen Art und Weise hergestellt sind, während zumindest eine der Verbindungen in an sich bekannter Weise dadurch gebildet ist, daß zwei aneinanderstoßende Teile stumpf aneinandergefügt sind. Bei einer solchen Verbindung kann, insbesondere wenn eines der Teile durch Innenhochdruckumformen hergestellt ist, vorgesehen sein, daß eine verbindungsknotenartige Ausformung an dem IHU- Teil ausgebildet ist, wie dies z.B. aus der US 6241310 bekannt ist. Fig. 6 zeigt schematisch und beispielhaft eine solche Verbindung im Bereich der B-Säule, wobei anstelle eines durchgehenden, mit zwei Aufnahmeoffnungen versehenen Schwellerprofils 6 ein mittleres Schwellerteil 24 und ein hinteres Schwellerteil 26 vorgesehen sind, die beiderseits (von vorn und hinten) an eine mit Ausformungen 28 versehene B-Säule 4' angesetzt und angeschweißt sind. Although the invention preferably provides that all connections between the A and B pillars, sills and side members are formed in the manner described by completely inserting a respective end section of one of the parts to be connected to one another, it can also be provided that only one or a few selected connections are made in the manner described, while at least one of the connections is formed in a manner known per se by the fact that two abutting parts are butted together. In the case of such a connection, in particular if one of the parts is produced by internal high pressure forming, it can be provided that a connection knot-like formation is formed on the hydroforming part, as is the case, for example, in US Pat. No. 6241310 is known. Fig. 6 shows schematically and by way of example such a connection in the area of the B-pillar, wherein instead of a continuous sill profile 6 provided with two receiving openings, a middle sill part 24 and a rear sill part 26 are provided, which are on both sides (from the front and rear) to one B-pillar 4 'provided with formations 28 are welded on.
