Abstract
Description
Die Erfindung betrifft eine Bodenlängsträgeranordnung an Kraftfahrzeugen nach dem Oberbegriff des Anspruchs 1.The invention relates to a floor side member arrangement on motor vehicles according to the preamble of claim 1.
Aus der
Mit der
Aufgabe der vorliegenden Erfindung ist es nunmehr, eine verbesserte Bodenlängsträgeranordnung an Kraftfahrzeugen, bestehend aus wenigstens zwei getrennt voneinander gefertigten und in Fahrzeuglängsrichtung nacheinander angeordneten und an einem Bodenblech festgelegten Hohlprofilen zu schaffen, die ihrerseits mit einfachen Mitteln eine zusätzliche Versteifung der Bodenstruktur und einen einfachen Toleranzausgleich gestattet sowie geeignet ist, für Fahrzeugplattformen mit unterschiedlichsten Radabständen Anwendung zu finden.Object of the present invention it is now an improved floor rail arrangement on motor vehicles, consisting of at least two separately manufactured and in the longitudinal direction of the vehicle successively arranged and fixed to a floor panel hollow profiles to create, which in turn, an additional simple means Stiffening of the floor structure and easy tolerance compensation is permitted and suitable for Vehicle platforms with different wheelbases application to find.
Erfindungsgemäß wird die Aufgabe in Verbindung mit den Merkmalen im Oberbegriff des Anspruchs 1 dadurch gelöst, dass die miteinander korrespondierenden Profilenden der Hohlprofile der Bodenlängsträgeranordnung in Fahrzeuglängsrichtung zueinander überlappend angeordnet sind. In einer vorteilhaften Ausgestaltung sind die miteinander korrespondierenden Profilenden der Hohlprofile ferner zueinander achsparallel angeordnet.According to the invention, the task is related solved with the features in the preamble of claim 1 in that the mutually corresponding profile ends of the hollow profiles of the Bottom longitudinal beam arrangement overlapping in the longitudinal direction of the vehicle are arranged. In an advantageous embodiment, they are together corresponding profile ends of the hollow profiles to each other arranged axially parallel.
Des weiteren können die besagten Profilenden in Fahrzeugquerrichtung zueinander beabstandet oder untereinander fest verbunden sein und zwar so, dass im Verbindungsbereich derselben ein örtlich begrenztes festigkeitserhöhendes Gesamtprofil gebildet ist. Eine Weiterbildung der Erfindung sieht vor, dass die miteinander korrespondierenden Profilenden der Hohlprofile derart untereinander verbunden sind, dass Querschnittsbereiche der Hohlprofile ineinanderdringen, indem definierte Profilausschnitte und/oder -einschnitte an einem oder beiden korrespondierenden Profilenden der Hohlprofile vorgesehen sind. Die korrespondierenden Profilenden sind vorzugsweise durch Schweißung, Klebung und/oder mittels mechanischer Verbindungsmittel, wie Schrauben oder Niete, untereinander und/oder mit dem Bodenblech fest verbunden.Furthermore, the said profile ends spaced from each other in the vehicle transverse direction or with each other be firmly connected in such a way that in the connection area of the same a localized festigkeitserhöhendes Overall profile is formed. A further development of the invention provides before that the mutually corresponding profile ends of the hollow profiles are interconnected such that cross-sectional areas of the Penetrate hollow profiles by defined profile sections and / or incisions on one or both corresponding profile ends the hollow profiles are provided. The corresponding profile ends are preferably by welding, Gluing and / or by means of mechanical connecting means, such as screws or rivets, firmly connected to each other and / or to the floor panel.
Fernerhin können die Hohlprofile langgestreckt und/oder gekrümmt ausgebildet sein, wobei ein gekrümmtes Hohlprofil so zu dem vor- und/oder nachgeordnetem Hohlprofil angeordnet respektive mit demselben verbunden ist, dass im Crashfall durch die gebildete "Kurbel" eine möglichst geringe Momentenkraft auf die Bodenlängsträgeranordnung aufgebracht wird.Furthermore, the hollow profiles can be elongated and / or curved be formed, with a curved Hollow profile arranged to the upstream and / or downstream hollow profile or connected to it in the event of a crash the "crank" formed one if possible low moment force is applied to the floor side member arrangement.
Weiter wird im Sinne der Erfindung vorgeschlagen, dass wenigstens ein Hohlprofil ein gesondertes gekrümmtes Verbindungsstück zwischen einem vorderen und einem hinteren Bodenlängsträger der Bodenträgeranordnung ist. Ebenso gehört zum Inhalt der Erfindung, dass wenigstens ein Hohlprofil ein Bodenlängsträger mit endseitig integrierter Krümmung ist.Further in the sense of the invention proposed that at least one hollow profile be a separate curved connector between a front and a rear floor longitudinal member of the floor support assembly is. Heard as well to the content of the invention that at least one hollow profile with a floor rail integrated curvature at the end is.
Die Erfindung wird nachstehend anhand der in den Zeichnungen schematisch dargestellten Ausführungsbeispiele näher erläutert. Es zeigen:The invention is illustrated below of the embodiments shown schematically in the drawings explained in more detail. It demonstrate:
Wie bereits oben dargetan, hat sich
jedoch in der Praxis gezeigt, dass aus der gekrümmten, beispielsweise "S"-förmigen
Gestaltung von Bodenlängsträgern, eine
Beeinträchtigung
der Steifigkeit der Trägerstruktur
resultiert, die im Crashfall im Verbindungsbereich
Erfindungsgemäß wird gem.
Gem. den
Den
Vorstehende erfindungsgemäße Ausgestaltung
einer Bodenlängsträgeranordnung
gestattet im übrigen
während
der Montage des Kraftfahrzeugs mit einfachen Mitteln auch einen
gegebenenfalls erforderlichen Toleranzausgleich der zusammenzufügenden Bauteile.
Ebenso ist diese Ausgestaltung besonders prädestiniert für Serienfertigungen,
die ihrerseits mit an sich gleichartigen Fahrzeugplattformen einhergehen,
jedoch unterschiedliche Radabstände
aufweisen. Infolge der überlappenden
Gestaltung der Hohlprofile
