Abstract
Description
Die Erfindung bezieht sich auf einen Seitenaufprallschutz, insbesondere für eine Aluminium- Spaceframe Struktur einer Personenkraftwagenkarosserie gemäß dem Oberbegriff des Anspruches 1.The invention relates to a Side impact protection, especially for an aluminum space frame Structure of a passenger car body according to the preamble of the claim 1.
Insbesondere bei Aluminium- Spaceframe Strukturen
von Personenkraftwagenkarosserien ist es bekannt,
Um bei einem derartigen Aufbau einer
Personenkraftwagenkarosserie eine Verbesserung des Seitenaufprallschutzes
zu erreichen, ist es aus der
Weiterhin ist aus der
Allen bekannten Gestaltungsformen von mit Dämpfungsmitteln oder Versteifungselementen ausgestatteten Trägern, insbesondere Schwellenn von Kraftwagenkarosserien ist gemeinsam, dass sich die Dämpfungsmittel bzw. die Versteifungselemente zumindest im Wesentlichen über die gesamte Länge des jeweiligen Trägers bzw. Schwellers hin erstrecken, was naturgemäß eine entsprechende Erhöhung des Gewichtes der Karosserie zur Folge hat. All known design forms of with damping agents or supports equipped with stiffening elements, in particular sleepers The common feature of motor vehicle bodies is that the damping means or the stiffening elements at least essentially via the entire length of the respective carrier or sills extend, which naturally a corresponding increase in Weight of the body.
Der Erfindung liegt daher die Aufgabe zugrunde einen Seitenaufprallschutz, insbesondere für eine Aluminium-Spaceframe Struktur einer Personenkraftwagenkarosserie aufzuzeigen, welcher ohne Verminderung der Schutzwirkung mit einer erheblich geringeren Gewichtserhöhung der gesamten Karosserie auskommt.The invention is therefore the object based on side impact protection, especially for an aluminum spaceframe To show structure of a passenger car body, which one without reducing the protective effect with a significantly lower one weight increase the entire body needs.
Diese Aufgabe wird erfindungsgemäß durch die im Anspruch 1 angegebenen Merkmale gelöst. Vorteilhafte Weiterbildungen und zweckmäßige Ausgestaltungen sind in den Unteransprüchen angegeben.This object is achieved by the Features specified in claim 1 solved. Advantageous further training and practical configurations are in the subclaims specified.
Die mit der erfindungsgemäßen Gestaltung eines Seitenaufprallschutzes für Personenkraftwagenkarosserien hauptsächlich erzielten Vorteile sind in erster Linie darin zu sehen, daß sich die Aussteifung des Schwellers mittels eines Mehrkammerhohlprofiles jeweils lediglich über einen Teil seiner Länge hin erstreckt, woraus eine Schutzwirkung eine nennenswerte Reduktion des Gesamtgewichtes der Karosserie des Personenkraftwagens resultiert.The with the design of a Side impact protection for Passenger car bodies are mainly achieved in advantages to see primarily in the fact that the sill is braced using a multi-chamber hollow profile only about each part of its length extends, from which a protective effect a significant reduction of the total weight of the body of the passenger car results.
Die Aussteifung des Schwellers besteht zweckmäßigerweise aus einem wenigstens zwei Kammern aufweisenden Hohlprofil, insbesondere einem Strangpressprofil, dessen Breite ein Mehrfaches seiner Höhe beträgt, und es ist vorteilhafterweise, zumindest im wesentlichen quer zu dessen Profilhöhe ausgerichtet sowie an zumindest an dessen Innenumfang im dem seinerseits durch ein Strangpressprofil gebildeten Schwellerprofil ausgebildeten Vorsprüngen, Leisten oder dergl. festgelegt. Der Einsatz eines Mehrkammer-Strangpressprofiles als Aussteifung für den Schweller gewährleistet dabei einerseits eine einfache Herstellung und andererseits eine einfache Montage.The sill is advantageously braced from a hollow profile having at least two chambers, in particular an extruded profile, the width of which is a multiple of its height, and it is advantageous, at least substantially transverse to it Profile height aligned as well as at least on its inner circumference an extruded profile formed sill profile formed projections, strips or the like. The use of a multi-chamber extruded profile as a bracing for guaranteed the sill on the one hand simple manufacture and on the other hand one easy installation.
Bei gleichbleibender Erhaltung der Vorteile hinsichtlich deren Herstellung und deren Montage kann eine weitere Verbesserung der Aussteifung des Schwellers dadurch erreicht werden, dass bei dem die Aussteifung bildenden Mehrkammer-Strangpressprofil wenigstens eine seiner mindestens zwei Kammern mit einem geschäumten Material ausgefüllt ist, wobei es im Interesse eines möglichst geringen Gewichtes der Aussteifung vorteilhaft ist, dass eine oder alle Kammern des die Aussteifung bildenden Strangpressprofiles mit geschäumtem Aluminium, vorzugsweise einem Längenabschnitt eines Profilmaterials aus geschäumtem Aluminium ausgefüllt sind.While maintaining the One can have advantages with regard to their manufacture and their assembly achieved further improvement in the stiffening of the sill that with the multi-chamber extrusion profile that forms the bracing at least one of its at least two chambers with a foamed material filled out is, in the interest of the lowest possible weight the stiffening is advantageous that one or all chambers of the the stiffening extruded profile with foamed aluminum, preferably a length section a profile material made of foamed Aluminum filled are.
