Abstract
Description
Die vorliegende Erfindung betrifft eine Tragstruktur für ein Kraftfahrzeug, insbesondere für einen Personenkraftwagen, mit den Merkmalen des Oberbegriffs des Anspruchs 1.The present invention relates a support structure for a motor vehicle, in particular for a passenger car, with the features of the preamble of claim 1.
Aus der
Bei der bekannten Tragstruktur durchdringt somit der Längsträger den kompletten Endquerträger, wodurch ein Anbau einer zusätzlichen Baugruppe in Fahrzeuglängsrichtung an den Tragrahmen erschwert ist.In the known support structure penetrates thus the side member the complete end cross member, making an extension of an additional Assembly in the vehicle longitudinal direction is difficult on the support frame.
Aus der
Die vorliegende Erfindung beschäftigt sich mit dem Problem, für eine Tragstruktur der eingangs genannten Art eine andere oder eine verbesserte Ausführungsform anzugeben, die insbesondere das Anbauen einer zusätzlichen Baugruppe vereinfacht.The present invention deals with the problem, for a support structure of the type mentioned another or a improved embodiment specify, in particular, the addition of an additional Assembly simplified.
Dieses Problem wird erfindungsgemäß durch den Gegenstand des unabhängigen Anspruchs gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This problem is inventively the subject of the independent Claim solved. Advantageous embodiments are the subject of the dependent Claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, den Längsträger nur durch die Innenschale hindurchzustecken und stirnseitig, noch im Inneren des Querträgers an der Außenschale zu befestigen. Durch diese Bauweise kann zum einen eine gewünschte Torsionssteifigkeit in diesem Abschnitt der Tragstruktur gewährleistet werden, wobei zum anderen die Außenschale an ihrer von der Innenschale abgewandten Außenseite relativ frei gestaltet werden kann, wodurch insbesondere das Anbauen einer weiteren Baugruppe relativ einfach realisierbar ist.The invention is based on the general idea the side member only durchzustecken through the inner shell and the front, still in Inside of the cross member on the outer shell to fix. By this construction, on the one hand, a desired torsional rigidity in this section of the support structure are ensured, and secondly the outer shell be designed relatively freely on their remote from the inner shell outside can, which in particular the cultivation of another assembly is relatively easy to implement.
Von besonderem Vorteil ist eine Ausführungsform, bei welcher eine Endbaugruppe ein Verbindungselement aufweist, das durch die Außenschale hindurch mit dem Längsträger verschraubt ist. Bei dieser Bauweise befindet sich die Außenschale zwischen dem Verbindungselement der Endbaugruppe und dem Längsträger. Durch die Verschraubung ist die Außenschale somit zwischen Längsträger und Verbindungselement eingespannt, so dass sich Verbindungselement und Längsträger über die Außenschale aneinander in Fahrzeuglängsrichtung abstützen. Durch diese Bauweise ergibt sich für die Befestigung der Außenschale am Längsträger und am Verbindungselement ein Formschluß über die Schrauben sowie ein Reib- oder Kraftschluß über die Einspannung. Andere, aufwendigere Verbindungstechniken, wie z.B. Schweißverbindungen, sind zur festen Anbindung des. Verbindungselements und des Längsträgers an der Außenschale nicht erforderlich. Die Herstellung der Tragstruktur kann somit zumindest in diesem Abschnitt vereinfacht werden. Die Verwendung einer Verschraubung zur Anbindung der Endbaugruppe an der Tragstruktur vereinfacht einen Austausch der Endbaugruppe. Beispielsweise umfasst die Endbaugruppe einen Frontstoßfänger oder einen Heckstoßfänger, der dadurch nach einer Beschädigung kostengünstig ausgetauscht werden kann.Of particular advantage is an embodiment in which an end assembly has a connecting element, the through the outer shell screwed through to the longitudinal member is. In this construction, the outer shell is located between the connecting element the end assembly and the side member. By The screw is the outer shell thus between the longitudinal member and connecting element clamped, so that connecting element and longitudinal members on the outer shell together in the vehicle longitudinal direction support. By this construction results for the attachment of the outer shell on the side member and on the connecting element a positive connection on the screws and a Friction or adhesion on the Clamping. Other, more expensive joining techniques, such as Welds, are for fixed connection of the connecting element and the longitudinal member the outer shell not mandatory. The production of the support structure can thus be simplified at least in this section. The usage a screw for connecting the end module to the support structure simplifies replacement of the end module. For example, includes the end assembly has a front bumper or a front bumper Rear bumper, the thereby after a damage economical can be exchanged.
Der Längsträger kann bei einer anderen Ausführungsform zumindest in einem in den Querträger eingesteckten Endabschnitt ein einseitig offenes Profil aufweisen. Ein derart profilierter Längsträger kann preiswert hergestellt werden. Zweckmäßig kann nun die offene Seite des Längsträgers innerhalb des Querträgers mit einem Schließteil verschlossen werden, das am Längsträger befestigt ist. Vorteilhafterweise erstreckt sich dieses Schließteil von der Innenschale bis zur Außenschale. Durch das Schließen des Profils mit Hilfe des Schließteils kann die Steifigkeit des Längsträgers und somit der kompletten Verbindung zwischen Querträger und Längsträger erheblich gesteigert werden. Insbesondere kommt es dabei zu Materialverdoppelungen, die in erhöhtem Maße zur Aussteifung beitragen.The side member may be at another embodiment at least in one inserted in the cross member End section have a unilaterally open profile. Such a thing profiled side member can be inexpensive getting produced. Appropriately now the open side of the side member inside of the crossbeam with a closing part be closed, attached to the side rail is. Advantageously, this closing part extends from the inner shell to the outer shell. By closing the Profiles with the help of the closing part can the stiffness of the side member and Thus, the entire connection between the cross member and side members are significantly increased. In particular, this leads to material doubling, which to an increased extent to the stiffening contribute.
Eine weitere Aussteifung der Verbindung zwischen Querträger und Längsträger kann dadurch erreicht werden, dass einerseits der Längsträger stirnseitig an einer Innenkonsole befestigt ist, wobei die Verschraubung zwischen Verbindungselement und Längsträger über die Konsole und durch die Außenschale erfolgt, so dass die Außenschale über die Konsole zwischen Verbindungselement und Längsträger eingespannt ist. Zweckmäßig sind die miteinander verschraubten Bauteile dazu mit geeigneten Flanschen ausgestattet, die bei ihrer Verspannung mit der Außenschale wieder zu Materialverdoppelungen führen. Weitere Materialverdoppelungen ergeben sich an den Anbindungsstellen zwischen der jeweiligen Konsole und dem Verbindungselement bzw. dem Längsträger. Darüber hinaus kann auch eine Außenkonsole vorgesehen sein, die am Verbindungselement befestigt ist und über die das Verbindungselement an der Außenseite der Außenschale befestigt ist.A further stiffening of the connection between the cross member and the longitudinal member can be achieved, that on the one hand the longitudinal member is frontally attached to an inner console, wherein the screw connection between the connecting element and longitudinal member via the console and through the outer shell, so that the outer shell on the console between the connecting element and longitudinal beams is clamped. Appropriately, the components screwed together are equipped with suitable flanges, which in their tension again lead to material doubling with the outer shell. Further doublings of material arise at the connection points between the respective console and the connecting element or the side member. In addition, an outer console may be provided, which is fastened to the connecting element and via which the connecting element is attached to the outside of the outer shell.
Weitere wichtige Merkmale und Vorteile der Erfindung ergeben sich aus den Unteransprüchen, aus den Zeichnungen und aus der zugehörigen Figurenbeschreibung anhand der Zeichnungen.Other important features and benefits The invention will become apparent from the dependent claims, from the drawings and from the associated Description of the figures with reference to the drawings.
