Abstract
Description
Die Erfindung bezieht sich auf eine Tragstruktur gemäß dem Oberbegriff des Anspruches 1 für eine Kraftwagenkarosserie.The invention relates to a support structure according to the generic term of claim 1 for a car body.

Keine der beiden vorgenannten, bekannten Bauweisen von Karosserietragstrukturen besitzt Mittel bzw. konstruktive Vorkehrungen um unfallbedingte, insbesondere aufprallbedingte Stoßkräfte in Karosserielängsrichtung vom Vorderwagen zum Hinterwagen hin bzw. umgekehrt weiterzuleiten. Dies resultiert nicht zuletzt aus der Art der gegenseitigen Verbindung der beiden Module bzw. Aufbaumodule der Karosserie- bzw. Karosserietragstruktur. Zum Weiteren scheint in beiden Fällen, wenn überhaupt so doch lediglich eine sehr kurze gegenseitige Überdeckung benachbarter Abschnitte bzw. Module der jeweiligen Kraftwagenkarosserietragstruktur vorgesehen zu sein, woraus naturgemäß eine vergleichsweise wenig stabile Verbindung resultiert.Neither of the above two known designs of body support structures has means or constructive arrangements about accident-related, in particular impact-related, impact forces in the longitudinal direction of the body forward from the front end to the rear end or vice versa. This results not least from the type of mutual connection of the two modules or body modules of the body or body support structure. Furthermore, in both cases if any so only a very short mutual overlap of adjacent sections or modules of the respective motor vehicle body support structure are provided to be, by nature a comparatively little stable connection results.
Die
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde eine Tragstruktur für eine Kraftwagenkarosserie zu schaffen, welche einerseits mit lediglich zwei Modulen auskommt und dabei anderseits auch den Einsatz unterschiedlicher Bauweisen und Materialien für die einzelnen Module zulässt, ohne eine unzureichende Stabilität der Verbindung benachbarter Module oder eine unzureichende Weiterleitung aufprallbedingter Stoßkräfte vom Vorderwagen zum Hinterwagen und umgekehrt in Kauf nehmen zu müssen.Based on this state of the art the invention has for its object a support structure for a motor vehicle body to create, which on the one hand needs only two modules and on the other hand also the use of different designs and materials for allows the individual modules, without insufficient stability the connection of neighboring modules or insufficient forwarding impact forces from impact To have to accept front car to rear car and vice versa.
Diese Aufgabe wird erfindungsgemäß durch die im Anspruch 1 angegebenen Merkmale gelöst. Vorteilhafte Weiterbildungen und zweckmäßige Ausgestaltungsformen sind in den Unteransprüchen angegeben.This object is achieved by the Features specified in claim 1 solved. Advantageous further training and practical designs are in the subclaims specified.
Einer der wesentlichsten Vorteile der erfindungsgemäßen Gestaltung der beiden einander zu einer Tragstruktur für einen Kraftwagenkarosserie ergänzenden Module ist darin zu sehen, dass beide Module über die gesamte Länge der Fahrgastzelle hin ineinandergreifen und somit bei montierter Tragstruktur über die gesamte Länge der Fahrgastzelle hin miteinander verbunden sind. Aus dieser Verbindungslänge resultiert eine vorzügliche Festigkeit der Tragstruktur, sowohl was die Durchleitung aufprallbedingter Stoßkräfte als auch die Steifigkeit in Querrichtung anlangt.One of the main advantages the design according to the invention the two form a support structure for a motor vehicle body supplementary Modules can be seen in the fact that both modules cover the entire length of the module Interlock passenger compartment and thus with assembled support structure over the whole length the passenger compartment are interconnected. The result of this connection length an excellent one Strength of the support structure, both what the conduction due to impact Shock forces as also the rigidity in the transverse direction.
Im Einzelnen führt die ineinandergreifende Ausbildung beider Module der Tragstruktur zu einer optimalen Weiterleitung und zumindest teilweisen Abstützung aus einem Aufprall resultierender Stoßkräfte an einem der die Fahrgastzelle begrenzenden und der jeweiligen Aufprallstelle gegenüberliegenden Strukturquerträger. Daraus folgt eine optimale Aufteilung der aus einem Aufprall resultieren Längskräfte innerhalb der Tragstruktur und damit die Möglichkeit zur einer Gewichtsverringerung der Tragstruktur gegenüber den bekannten, aus Modulen gebildeten Tragstrukturen. Darüber hinaus gestattet die erfindungsgemäße Ausgestaltung der gegenseitigen Verbindung der beiden Module zu einer Tragstruktur den Einsatz unterschiedlicher Bauweisen und unterschiedlicher Materialien für die Ausbildung der beiden Module, wobei eine vorteilhafte Gestaltungsweise darin gesehen wird, dass das den Vorderwagen und das Bodenblech der Fahrgastzelle umfassende Modul als eine in herkömmlicher Weise aus Stahlblech hergestellte Rahmenstruktur und das den Hinterwagen bildende und auch wenigstens die Schweller bildende Längsträger umfassende Modul als eine in Aluminium-Spaceframe-Bauweise ausgebildete Rahmenstruktur ausgeführt ist.In particular, the interlocking design of both modules of the support structure leads to an optimal forwarding and at least partial support resulting from an impact of impact forces on one of the structural crossbeams delimiting the passenger cell and opposite the respective point of impact. This results in an optimal distribution of the longitudinal forces resulting from an impact within the supporting structure and thus the possibility to reduce the weight of the support structure compared to the known support structures formed from modules. In addition, the inventive design of the mutual connection of the two modules to a support structure allows the use of different designs and different materials for the formation of the two modules, an advantageous design is seen in that the module comprising the front end and the floor panel of the passenger compartment as one Frame structure made in conventional manner from sheet steel and the module forming the rear carriage and also comprising at least the sill side members are designed as a frame structure constructed in an aluminum spaceframe construction.
Mit der in einer Aluminium-Spaceframe-Bauweise ausgebildeten, im Wesentlichen den Hinterwagen bildenden Rahmenstruktur kann, je nach Ausstattung des Fahrzeuges mit Front- oder Heckmotor, außer den seitliche Längsträger bildenden Schwellern auch ein einen Mitteltunnel aussteifender Längsträger verbunden sein, der sich ausgehend von einem Stirnwandquerträger der Rahmenstruktur des Vorderwagens zu einem Fersenträger der Rahmenstruktur des Hinterwagens hin erstreckt.With the in an aluminum spaceframe construction trained frame structure, which essentially forms the rear carriage can, depending on the equipment of the vehicle with front or rear engine, except the lateral side members forming Sills are also connected to a side member stiffening a central tunnel be the starting from a bulkhead cross member Frame structure of the front end to a heel support Frame structure of the rear end extends.
Eine weitere vorteilhafte zusätzliche Aussteifung der Tragstruktur für eine Kraftwagenkarosserie wird ferner dadurch erreicht, dass mit dem freien Ende jedes der beiden jeweils einen Längsträger bildenden Schweller ein aufragend ausgerichteter Hohlprofilabschnitt verbunden ist, welcher bei montierter Tragstruktur als Verstärkung in die A-Säulen bildende Hohlräume der den Vorderwagen bildenden Rahmenstruktur eingreift.Another advantageous additional Bracing of the supporting structure for a motor vehicle body is also achieved in that with the free end of each of the two sills forming a longitudinal beam outstandingly aligned hollow profile section is connected, which when the support structure is installed as reinforcement in the A-pillars cavities engages the frame structure forming the front end.
Das Bodenblech kann über seine beiderseits des Mitteltunnels liegenden Bereiche hin in vorteilhafter Weise mittels abgewinkelter Randbereiche und, beispielsweise durch Nieten oder Schrauben gebildeter, Fügemittel sowohl mit dem die Fahrgastzelle nach hinten begrenzenden Fersenträger des Hinterwagens als auch über seine an den Mitteltunnel angrenzenden Längsränder hin in vergleichbarer Weise mit dem den Mitteltunnel aussteifenden Längsträger verbunden werden, wobei das Bodenblech vorzugsweise jeweils mit nach oben gerichteten Randabstellungen versehen ist. Hinsichtlich der Verbindung mit dem den Mitteltunnel aussteifenden Längsträger ist dabei der der Befestigung des Bodenbleches am Längsträger dienende Randbereich des zweckmäßigerweise auf dem zugehörigen Randbereich des Trägers aufliegend ausgerichtet.The floor pan can over its areas lying on either side of the central tunnel are advantageous Way by means of angled edge areas and, for example by Rivets or screws formed, both with the Passenger cell rear-heel of the rear end as well as over his comparable to the longitudinal edges adjacent to the central tunnel are connected to the longitudinal beam stiffening the central tunnel, whereby the bottom plate is preferably each with upward edge stops is provided. Regarding the connection with the the middle tunnel stiffening side member the edge area serving to fasten the floor panel to the side member is expedient on the associated Edge area of the carrier aligned on top.
Die Erfindung ist in der nachfolgenden Beschreibung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert.The invention is in the following Description based on an embodiment shown in the drawing explained in more detail.
