Der Vorteil des Einsetzens von Strangpressprofil-Halbschalen gegenüber Pressschalen liegt darin, dass diese keine scharten Kanten aufweisen und dass eine Punktschweißung ermöglicht ist, wohingegen Pressschalen scharfe Kanten haben, die vorteilhaft nur durch ununterbrochene (durchgehende) Stirnflächen-Schweißnähte entschärft werden können. Als Nachteil muss angesehen werden, dass ein aus zwei miteinander verschweißten Halbschalen gebildetes Profil eine Abwinklung durch eine Umformung nicht zulässt und nur gerade Profillängen für die Herstellung eines Modulträgers zur Verfügung stehen.Of the Advantage of the use of extruded half-shells over pressing shells is that they have no sharp edges and that a spot weld allows whereas press cups have sharp edges which are beneficial can be defused only by uninterrupted (continuous) face welds. When Disadvantage must be considered that a formed of two half-shells welded together Profile does not allow angling through a deformation and only straight profile lengths for the Production of a module carrier be available.
Es ist Aufgabe der Erfindung, einen Modulträger aus Leichtmetall-Strangpresskomponenten nach dem Oberbegriff des Anspruchs 1 zu fertigen, der Abwinklungen und Querschnittsunterschiede aufweist.It It is an object of the invention to a module carrier made of light metal extruded components to produce the preamble of claim 1, the bends and Has cross-sectional differences.
Diese Aufgabe wird bei einem Modulträger nach dem Oberbegriff des Anspruchs 1 durch dessen kennzeichnende Merkmale gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen aufgeführt.These Task is with a module rack after the preamble of claim 1 by its characterizing features solved. Advantageous embodiments are listed in the subclaims.
Die Erfindung besteht darin, dass bei einem Modulträger für ein Fahrzeug, der aus Leichtmetall-Strangpresskomponenten und dabei in seiner Längsausdehnung aus mehreren Hohlprofilabschnitten besteht, die Strangpresskomponenten Halbschalen sind, die zu einem Hohlprofil verschweißt sind. Dabei weisen die einzelnen Hohlprofilabschnitte jeweils einen vorbestimmten Querschnitt auf. Hohlprofilabschnitte gleichen Querschnitts sind durch einen Gehrungsschnitt und Verschweißung gefügt, und Hohlprofilabschnitte unterschiedlichen Querschnitts sind jeweils über ein Kopplungselement miteinander verbunden. Die Gehrungsschnitte ermöglichen beliebige Abwinklungen. Dabei sind die Gehrungsschnitte zur Herstellung einer Abwinklung mit einem vorbestimmten Winkel jeweils mit dem halben vorbestimmten Winkel am jeweiligen Hohlprofilabschnitt angebracht. Die Fertigung von Leichtmetall-Strangpresshalbschalen ist wegen der um ein Vielfaches niedrigeren Werkzeugkosten – niedrige Kosten der Strangpressdüsen gegenüber hohen Kosten der Halbschalenprofile für Presswerkzeuge zur Fertigung von Presshalbschalen – um ein Vielfaches kostengünstiger. Unabhängig von den niedrigeren Kosten sind die Strangpressdüsen schneller verfügbar, so dass erforderliche Profiländerungen schneller umsetzbar sind. Durchgehende Schweißnähte beim Fügen der Leichtmetall-Strangpresshalbschalen sind nicht erforderlich, da diese nicht scharfkantig sind.The Invention is that in a module carrier for a vehicle made of light metal extruding components and in its longitudinal extent consists of several hollow profile sections, the extruded components Half shells are welded to a hollow profile. there each of the individual hollow profile sections have a predetermined Cross-section on. Hollow profile sections of the same cross-section are joined by a miter cut and welding, and hollow profile sections different cross-section are each connected to each other via a coupling element. The miter cuts enable any bends. Here are the miter cuts for production a bend with a predetermined angle respectively with the half predetermined angle attached to the respective hollow profile section. The production of light metal extrusion half shells is due to many times lower tooling costs - low Cost of extrusion dies across from high cost of half-shell profiles for press tools for manufacturing from pressed half shells - um many times cheaper. Independently of the lower cost, the extrusion dies are available more quickly, so that required profile changes are faster to implement. Continuous welds when joining the light metal extrusion half shells are not required because they are not sharp.
Als Stranpresshalbschalen werden dabei auch solche angesehen, die in ihrem Inneren mit Versteifungen versehen sind und auch als Hohlprofil ausgebildet sein können. Vorteilhaft sind die Halbschalen an einer der beiden Längskanten mit einer Längsnut zur Aufnahme der längsnutfreien Längskante der jeweils anderen mit dieser zu fügenden Strangpresshalbschale nach Art einer Nut-Feder-Anordnung versehen. Eine derartige Querschnittsausbildung wird durch die Gestaltung des Strangpresswerkzeuges in einfacher Weise ermöglicht. Die zwei miteinander zu fügenden Strangpresshalbschalen können somit aneinander arretiert und erleichtert gefügt werden, wobei das Fügeverfahren wegen der fehlenden Scharfkantigkeit der Kanten eine Punktschweißung sein kann.As Stranpresshalbschalen while those are considered, which are provided in their interior with stiffeners and can also be designed as a hollow profile. Advantageously, the half-shells are provided on one of the two longitudinal edges with a longitudinal groove for receiving the längsnutfreien longitudinal edge of the other with this to be joined extruded half shell in the manner of a tongue and groove arrangement. Such a cross-sectional formation is made possible by the design of the extrusion tool in a simple manner. The two extruded half shells to be joined together can thus be locked together and relieved, the joining process can be a spot weld due to the lack of sharp edges.
Der Modulträger ist an seinen freien Enden mit Befestigungselementen, insbesondere Schraubböcken, zum Verbinden mit der Fahrzeugkarosserie versehen. Überdies kann in den Strangpresshalbschalen eine im Querschnitt kreuzförmige Nut mit der Öffnung zur Außenseite der Anordnungswandung beim Strangpressen mit einem entsprechend gestalteten Werkzeug mit eingebracht sein, die einer erleichterten Anordnung von Befestigungselementen dient. In diese Nut kann ein vorgefertigtes Band mit an diesem angeordneten Befestigungselementen, beispielsweise Stanzmuttern, eingeschoben werden, das dann nach dem Fügeprozess mit dem benachbarten Hohlprofilabschnitt oder Kopplungsteil fest eingeschlossen ist. Die Befestigungselemente dienen dann der erleichterten Anordnung von Komponenten. Alternativ dazu oder zusätzlich und in Abhängigkeit von der Position der anzuordnenden Komponenten kann auch wenigstens eine der beiden Strangpresshalbschalen in ihrer Längsausdehnung mit einem Flansch zur Anordnung von Befestigungselementen und auch von Zentrierlöchern versehen sein. Gleichermaßen ist es möglich, in eine Strangpresshalbschale beim Strangpressen eine einfache Nut für den Eingriff von Arretierungselementen, beispielsweise von anzuordnenden Komponenten, einzubringen, die den Montageprozess erleichtern.Of the module carrier is at its free ends with fasteners, in particular Schraubböcken, provided for connection to the vehicle body. moreover can in the extrusion half shells a cross-sectional cross-shaped groove with the opening to the outside the Anordnungswandung during extrusion with a corresponding designed tool to be introduced, which facilitated one Arrangement of fasteners is used. In this groove can one prefabricated tape with arranged on this fasteners, for example Punch nuts are inserted, then after the joining process firmly enclosed with the adjacent hollow profile section or coupling part is. The fasteners then serve the facilitated arrangement of components. Alternatively or additionally and in dependence from the position of the components to be arranged can also at least one of the two extruded half shells in their longitudinal extent with a flange for the arrangement of fasteners and also of centering holes be provided. equally Is it possible, in an extrusion half shell during extrusion a simple groove for the Engagement of locking elements, for example, to be arranged Components that facilitate the assembly process.
