Abstract
Description
Die Erfindung betrifft ein mittels einer Rahmenanordnung an einem vorderen Ende eines Fahrzeugrahmens eines Lastkraftwagens zu befestigendes Rahmenvorderteil der im Oberbegriff des Patentanspruchs 1 angegebenen Art.The The invention relates to a means of a frame assembly at a front End of a vehicle frame of a truck to be fastened Frame front part specified in the preamble of claim 1 Art.
Ein
derartiges Rahmenvorderteil ist beispielsweise aus der
Als nachteilig bei diesen bekannten Rahmenvorderteilen ist der Umstand anzusehen, dass sehr viele Bauteile und Baugruppen im Bereich des Rahmenvorderteils angeordnet sind, und sehr viele Funktionen – wie beispielsweise die Energieabsorption im Falle eines Frontalaufpralls – durch das Rahmenvorderteil erfüllt werden müssen. Aus diesem Grund ist das Rahmenvorderteil zumeist sehr stabil und komplex ausgebildet, was sich in einem dementsprechend hohen Gewicht niederschlägt.When disadvantageous in these known frame front parts is the fact to look at that very many components and assemblies in the frame of the front frame and many functions - such as energy absorption in the event of a frontal impact - through the front frame Fulfills Need to become. For this reason, the front frame is usually very stable and Complex, resulting in a correspondingly high weight reflected.
Aufgabe der vorliegenden Erfindung ist es daher, ein Rahmenvorderteil der eingangs genannten Art so zu verbessern, dass sich eine gewichtsgünstigere Konstruktion realisieren lässt.task The present invention is therefore a front frame of the to improve the type mentioned above so that a lighter weight Construction can be realized.
Diese Aufgabe wird erfindungsgemäß durch ein Rahmenvorderteil mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen und nicht-trivialen Weiterbildungen der Erfindung sind in den übrigen Patentansprüchen beschreiben.These The object is achieved by a Frame front part solved with the features of claim 1. advantageous Embodiments with appropriate and non-trivial developments of the invention are described in the remaining claims.
Bei dem Rahmenvorderteil nach der Erfindung ist zumindest eine Anzahl von tragenden bzw. mittragenden Bauteilen vorgesehen, welche aus einem faserverstärkten Kunststoff hergestellt sind. Ein derartiger faserverstärkter Kunststoff zeichnet sich insbesondere dadurch aus, ähnliche Materialeigenschaften wie beispielsweise die im Stand der Technik für derartige Rahmenvorderteile bislang verwendeten Metalllegierungen aufweisen. Insbesondere hinsichtlich der statischen und dynamischen Steifigkeit, des Energieabsorptionsvermögens und der Verschleißbeständigkeit haben sich Bauteile aus faserverstärktem Kunststoff als besonders vorteilhaft gezeigt, da sie darüber hinaus ein relativ zu Metalllegierungen gesehen äußerst geringes Gewicht aufweisen. Darüber hinaus sind faserverstärkte Kunststoffe sehr prozesssicher und kostengünstig herzustellen und zu verarbeiten, so dass insgesamt ein sehr preisgünstiges Rahmenvorderteil geschaffen werden kann.at the frame front part according to the invention is at least a number provided by supporting or contributing components, which from a fiber reinforced Plastic are made. Such a fiber reinforced plastic is characterized in particular by similar material properties such as those in the prior art for such front frame parts have previously used metal alloys. In particular with regard to static and dynamic stiffness, energy absorption capacity and the wear resistance have fiber reinforced plastic components as special shown advantageous because they are above In addition, a relative to metal alloys have extremely low weight. About that In addition, fiber reinforced To manufacture and process plastics very reliably and inexpensively, so that created a very reasonably priced frame front can be.
Als weiter vorteilhaft hat es sich gezeigt, insbesondere Teile einer energieabsorbierenden Einrichtung des Frontunterfahrschutzes – wie beispielsweise zwei seitliche Deformationselemente und ein diese miteinander verbindender Querträger – aus faserverstärktem Kunststoff herzustellen, da dieser ein relativ hohes Energieabsorptionsvermögen zur Aufnahme von Aufprallenergie im Falle einer Frontalkollision aufweist und darüber hinaus bei einer demgemäßen Zerstörung der Deformationselemente sehr gleichmäßig und ohne Kraftspitzen die anfallende Energie verzehren kann.When It has also been found to be advantageous, in particular parts of a Energy-absorbing device of the front underrun protection - such as two lateral deformation elements and one connecting them together Crossmember - made of fiber-reinforced plastic as this has a relatively high energy absorption capacity for Recording of impact energy in the event of a frontal collision and above with a demolished demolition of Deformation elements very evenly and without force peaks the can consume accumulated energy.
Als weiter vorteilhaft hat es sich gezeigt, Bauteile der den Frontunterfahrschutz tragenden Stützanordnung aus faserverstärktem Kunststoff zu gestalten. Da der Frontunterfahrschutz äußerst stabil am Rahmenvorderteil bzw. am Fahrzeugrahmen des Lastkraftwagens abgestützt sein muss, ist dieser entsprechend komplex bzw. massiv gestaltet. Durch die Verwendung zumindest einer Anzahl von Bauteilen aus faserverstärktem Kunststoff kann bei der Stützanordnung erheblich an Baugewicht eingespart werden.When further advantageous, it has been shown, components of the front underrun protection carrying support arrangement made of fiber-reinforced To make plastic. Since the front underrun protection extremely stable on Front frame or be supported on the vehicle frame of the truck must, this is designed accordingly complex or massive. By the use of at least a number of components made of fiber-reinforced plastic can in the support arrangement be saved considerably in construction weight.
In weiterer Ausgestaltung der Erfindung kann das Rahmenvorderteil eine Kühleranordnung umfassen, welche sich vorzugsweise nach unten hin bis in den Bereich des Frontuntefahrschutzes erstreckt und eine Tragstruktur mit einer Mehrzahl von sich in Fahrzeughochrichtung erstreckenden Kühlerträgern aufweist, welche aus faserverstärktem Kunststoff hergestellt sind. Durch eine derartige Kühleranordnung bzw. Tragstruktur kann eine in Fahrzeugquerrichtung am vorderen Ende des Lastkraftwagens verlaufende Rahmenanordnung geschaffen werden, welche beispielsweise bei einem Frontalcrash sowohl oberhalb wie auch unterhalb des Fahrzeugrahmens lastverteilend wirkt.In Another embodiment of the invention, the frame front part a Include cooler assembly, which preferably down to the area of the front protection extends and a support structure with a plurality of in the vehicle vertical direction having extending radiator supports, which made of fiber-reinforced Plastic are made. By such a cooler arrangement or support structure may be in the vehicle transverse direction at the front End of the truck running frame assembly created which, for example, in a frontal crash both above as well as below the vehicle frame load distributing acts.
Weiterhin vorteilhaft hat es sich gezeigt, Lagerkonsolen oder andere Bauteile einer vorderen Fahrerhauslagerung am Rahmenvorderteil anzuordnen und aus faserverstärktem Kunststoff zu gestalten, da derartige Bauteile zur Halterung des Fahrerhauses zumeist äußerst stabil – und bislang im Stand der Technik äußerst schwer – hergestellt werden müssen.Further advantageous, it has been shown to arrange bearing brackets or other components of a front cab storage on the front frame and made of fiber-reinforced plastic to decorate th, since such components for holding the cab usually extremely stable - and so far extremely difficult in the art - must be made.
Schließlich kann eine zusätzliche Versteifung von faserverstärkten Kunststoffteilen im Bereich des Rahmenvorderteils dadurch erreicht werden, dass bereichsweise Verstärkungseinlagen z. B. aus Metall vorgesehen werden, welche relativ einfach mit dem faserverstärkten Kunststoff verbunden bzw. in diesen eingebettet werden können.Finally, can an additional Stiffening of fiber reinforced Plastic parts in the area of the front frame achieved by be that partially reinforcing deposits z. B. be provided from metal, which relatively easy with the fiber reinforced Plastic can be connected or embedded in these.
