Abstract
Description
Die Erfindung betrifft einen aus Einzelprofilen gefügten Längsträger eines Kraftfahrzeuges nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to a longitudinal beam of a motor vehicle, which is joined from individual profiles Preamble of claim 1.

Die Erfindung beschäftigt sich mit dem Problem, im vorderen Bereich eines Personenkraftfahrzeuges bei einer in dem Fahrzeug vorgegebenen Lage der Längsträger zumindest in lokal begrenzten Bereichen den zur Verfügung stehenden Einbau- beziehungsweise Funktionsraum in Fahrzeugquerrichtung zur Aufnahme von Einbau- beziehungsweise Funktionselementen bei unverändertem Querabstand der Längsträger zu erweitern.The Invention busy dealing with the problem, in the front area of a passenger vehicle at least in a predetermined position in the vehicle of the longitudinal members in locally limited areas the available installation or Functional space in the vehicle transverse direction for receiving installation or functional elements with unchanged Transverse distance of the side members to expand.
Gelöst wird dieses Problem durch die Ausbildung eines gattungsgemäßen Längsträgers nach den kennzeichnenden Merkmalen des Patentanspruchs 1.Is solved This problem by the formation of a generic longitudinal member according to the characterizing features of claim 1.
Zweckmäßige und vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.Appropriate and advantageous embodiments are the subject of the dependent claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, einen Fahrzeug-Längsträger aus insbesondere stranggepreßten Einzelprofilen zusammenzusetzen, wobei seitliche Freiräume lediglich in einem der Profile vorgesehen werden und die Stabilitätsminderung im Bereich dieser den Freiraum enthaltenden beziehungsweise bildenden Profile durch Nachbarprofile verstärkt werden. Zu diesem Zweck können die Nachbarprofile eine beschränkt auf diesen Verstärkungsbereich erhöhte Stabilität aufweisen.The Invention is based on the general idea of a vehicle side member especially extruded Assemble individual profiles, with lateral free space only be provided in one of the profiles and the stability reduction in the area of this free space containing or forming Profiles are reinforced by neighboring profiles. For this purpose, the Neighboring profiles one limited on this gain area increased stability exhibit.
Der Längsträger kann vorteilhafterweise durch in Längsrichtung und Querrichtung aneinandergereihte Einzelprofile aufgebaut sein.Of the Side member can advantageously by in the longitudinal direction and transverse direction juxtaposed individual profiles be constructed.
Die Einzelprofile können untereinander insbesondere verschweißt sein.The Single profiles can in particular be welded together.
Die Einzelprofile sind vorteilhafterweise als innen verrippte Hohlprofile ausgebildet und weisen untereinander unterschiedliche Steifigkeiten durch unterschiedliche Innenstrukturen auf.The Individual profiles are advantageously as internally ribbed hollow profiles trained and have different stiffnesses through different internal structures.
Bei den durch Ausnehmungen in den Profilen geschaffenen Freiräumen des Längsträgers können die angeschnittenen und damit offenen Hohlräume der Einzelprofile durch Verschlußelemente verschlossen werden. Solche Verschlußelemente können insbesondere Einschnapp- beziehungsweise einpressbare Kunststoffstopfen sein.at created by recesses in the profiles open spaces of the Longitudinal member can the truncated and thus open cavities of the individual profiles closure elements be closed. Such closure elements can in particular snap-in or be pressed plastic stopper.
