Abstract
Bodenlängsträgeranordnung an Kraftfahrzeugen, bestehend aus wenigstens zwei getrennt voneinander gefertigten und in Fahrzeuglängsrichtung nacheinander angeordneten und an einem Bodenblech festgelegten Hohlprofilen, wobei die miteinander korrespondierenden Profilenden der Hohlprofile (2, 3, 4) in Fahrzeuglängsrichtung zueinander überlappend angeordnet sind, dadurch gekennzeichnet, dass die miteinander korrespondierenden Profilenden der Hohlprofile (2, 3, 4) zueinander achsparallel angeordnet sind.Bodenlängsträgeranordnung on motor vehicles, consisting of at least two separately manufactured and arranged in the vehicle longitudinal direction successively and fixed to a floor panel hollow profiles, wherein the mutually corresponding profile ends of the hollow sections (2, 3, 4) are arranged overlapping each other in the vehicle longitudinal direction, characterized in that the one another corresponding profile ends of the hollow profiles (2, 3, 4) are arranged axially parallel to each other.
Description
Die Erfindung betrifft eine Bodenlängsträgeranordnung an Kraftfahrzeugen nach dem Oberbegriff des Anspruchs 1.The invention relates to a Bodenlängsträgeranordnung on motor vehicles according to the preamble of

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.The object of the present invention is now to provide an improved Bodenlängsträgeranordnung of motor vehicles consisting of at least two separately manufactured and arranged in the vehicle longitudinal direction successively and fixed to a floor panel hollow sections, which in turn allows simple means an additional stiffening of the soil structure and a simple tolerance compensation and is suitable to find application for vehicle platforms with different wheelbases.
Erfindungsgemäß wird die Aufgabe in Verbindung mit den Merkmalen im Oberbegriff des Anspruchs 1 dadurch gelöst, dass die miteinander korrespondierenden Profilenden der Hohlprofile zueinander achsparallel angeordnet sind.According to the invention the object is achieved in conjunction with the features in the preamble of
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 in the vehicle transverse direction can be spaced apart from each other or firmly connected to each other in such a way that in the connection region thereof a localized strength-increasing overall profile is formed. A development of the invention provides that the mutually corresponding profile ends of the hollow profiles are interconnected such that cross-sectional areas of the hollow profiles intermesh by defined profile sections and / or incisions are provided on one or both corresponding profile ends of the hollow sections. The corresponding profile ends are preferably firmly connected to each other by welding, gluing and / or by means of mechanical connection means, such as screws or rivets, and / or with 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. 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.Furthermore, the hollow profiles can be elongate and / or curved, with a curved hollow profile is arranged to the front and / or downstream hollow profile respectively connected to the same that applied in the event of a crash by the "crank" formed as low as possible torque force on the Bodenlängsträgeranordnung becomes. Next is proposed in the sense of the invention that at least one Hollow profile is a separate curved connecting piece between a front and a rear floor side member of the bottom support assembly. Likewise, the content of the invention that at least one hollow profile is a bottom rail with end integrated curvature.
Die Erfindung wird nachstehend anhand der in den Zeichnungen schematisch dargestellten Ausführungsbeispiele näher erläutert. Es zeigen:The invention will be explained in more detail with reference to the embodiments schematically illustrated in the drawings. Show it:
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
