Abstract
Tragstruktur eines Kraftfahrzeugs mit einer Frontlängsträger aufweisenden Fronttragstruktur (1), wobei an den Frontlängsträgern mindestens ein Querträger befestigt ist, dadurch gekennzeichnet, dass an dem mindestens einen Querträger mindestens ein Deformationselement (8) befestigt ist.supporting structure a motor vehicle with a front longitudinal member having front support structure (1), whereby at the front end members at least a cross member attached is, characterized in that on the at least one cross member at least a deformation element (8) is attached.
Description
Die Erfindung betrifft eine Tragstruktur eines Kraftfahrzeugs mit einer Frontlängsträger aufweisenden Fronttragstruktur gemäß dem Oberbegriff des Patentanspruchs 1.The The invention relates to a support structure of a motor vehicle with a Frontlängsträger having Front support structure according to the preamble of claim 1
Die Tragstruktur der Karosserie eines Kraftfahrzeuges kann in die Fronttragstruktur, die Bodentragstruktur und die Hecktragstruktur unterteilt werden. Dabei ermöglicht der Fahrzeugbau die Fertigung der gesamten Tragstruktur aus Aluminium, wobei Bleche, Stangenpressprofile und Gussteile verwendet werden.The Carrying structure of the body of a motor vehicle can be in the front support structure, the floor support structure and the rear support structure are divided. It allows the vehicle manufacturing the production of the entire support structure made of aluminum, where sheets, bar extrusions and castings are used.
Die
Fronttragstruktur eines Kraftfahrzeugs weist in der Regel mindestens
zwei Längsträger auf, die
durch mindestens einen Querträger
miteinander verbunden sind, wie es beispielsweise in der Druckschrift
Einem Kraftfahrzeug mit Mittelmotor oder Heckmotor steht bei einem Frontalzusammenstoß die Brennkraftmaschine als Blockbildungselement zur Energieabsorption nicht zur Verfügung.a Motor vehicle with mid-engine or rear engine is the internal combustion engine in a head-on collision not available as a blocking element for energy absorption.
Daraus entsteht die Notwendigkeit, die Fronttragstruktur des Kraftfahrzeuges so auszugestalten, dass besonders viel Aufprallenergie absorbiert werden kann. Dabei wird bei einem Kraftfahrzeug mit Heckmotor der Raum zwischen den mindestens zwei Frontlängsträgern zum Ausbilden eines Kofferraumes verwendet. Insbesondere bei einem Pfahlaufprall sind dadurch Deformationen bis in die Fahrgastzelle hinein zu befürchten. from that arises the need, the front support structure of the motor vehicle to design so that absorbs a lot of impact energy can be. This is in a motor vehicle with rear engine of Space between the at least two front longitudinal members to form a trunk used. In particular, in a pile impact are deformations to fear into the passenger compartment into it.
Der Erfindung liegt die Aufgabe zugrunde, eine Tragstruktur eines Kraftfahrzeugs mit einer Frontlängsträger aufweisenden Fronttragstruktur gemäß dem Oberbegriff es Patentanspruchs 1 anzugeben, bei der die Fronttragstruktur so ausgebildet ist, dass sie insbesondere bei einem Pfahlaufprall eine hohe Energieabsorption aufweist. Dabei soll die Fronttragstruktur kostengünstig herzustellen sein.Of the Invention is based on the object, a support structure of a motor vehicle having a front side member Front support structure according to the preamble specify it patent claim 1, in which the front support structure so is formed so that it is particularly high in a pile impact Having energy absorption. In this case, the front support structure is inexpensive to manufacture be.
Diese Aufgabe wird erfindungsgemäß durch das Merkmal im Kennzeichen des Patentanspruchs 1 gelöst, wonach an dem mindestens einen mit den Frontlängsträgern verbundenen Querträger mindestens ein Deformationselement befestigt ist.These The object is achieved by the Feature solved in the characterizing part of claim 1, which according to the at least one connected to the front side members crossbeam at least one deformation element is attached.
In einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass an dem mindestens einen Deformationselement und auf dem mindestens einen Querträger Formteile befestigt sind, die eine Batterieaufnahme zur Montage einer Kraftfahrzeugbatterie bilden.In an advantageous embodiment of the invention is provided that on the at least one deformation element and on the at least a crossbeam Molded parts are attached, which is a battery holder for mounting to form a motor vehicle battery.
Das Kraftfahrzeug verfügt über einen Kühlmittelkreislauf zur Kühlung der Brennkraftmaschine. Dabei ist vorgesehen, dass als weiteres Deformationselement eine aus Leichtmetall gefertigte Kühlmittelleitung zwischen dem mindestens einen Querträger und dem mindestens einen Deformationselement angeordnet ist.The Motor vehicle has a Coolant circuit for cooling the internal combustion engine. It is envisaged that as another Deformation element made of a light metal coolant line between the at least one cross member and the at least one Deformation element is arranged.
In einer weiteren vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass der mindestens eine Querträger der Querlenker Fahrwerksaufnahme ist, der zur Befestigung eines Querlenkers der Vorderradaufhängung ausgebildet ist.In a further advantageous embodiment of the invention is provided that the at least one cross member The wishbone chassis mount is for attaching a Wishbone of the front suspension is trained.
Dabei ist vorgesehen, dass die Brennkraftmaschine des Kraftfahrzeugs im Heck angeordnet ist, dass das Fahrwerk des Kraftfahrzeugs als Allradantrieb ausgebildet ist, und dass das Kraftfahrzeug als Sportwagen ausgebildet ist.there is provided that the internal combustion engine of the motor vehicle in Rear is arranged that the chassis of the motor vehicle as four-wheel drive is formed, and that the motor vehicle is designed as a sports car is.
In einer letzten vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass die Tragstruktur des Kraftfahrzeugs aus Leichtmetall, insbesondere aus Aluminium, hergestellt ist.In a last advantageous development of the invention is provided that the supporting structure of the motor vehicle made of light metal, in particular of Aluminum, is made.
Eine derartig ausgebildete Fronttragstruktur weist auch bei einem Pfahlaufprall eine hohe Energieabsorption auf, wobei durch das mindestens eine zwischen den Frontlängsträgern angeordnete, mit dem mindestens einen Querträger verbundene Deformationselement eine Deformation bis in die Fahrgastzelle hinein vermieden wird.A such trained front support structure also has a pile impact a high energy absorption, wherein by at least one between the front longitudinal members arranged, with the at least one cross member connected deformation element deformation into the passenger compartment is avoided.
Im folgenden ist die erfindungsgemäße Tragstruktur eines Kraftfahrzeugs anhand von einem Ausführungsbeispiel im Zusammenhang mit zwei Figuren dargestellt und erläutert.in the The following is the support structure according to the invention of a motor vehicle based on an embodiment in connection illustrated and explained with two figures.
Es zeigen:It demonstrate:
Zur Absorption von Aufprallenergien, die bei Frontalstößen auf die Fronttragstruktur einwirkenden, sind an der Fronttragstruktur sechs Frontlängsträger ausgebildet, wovon aus Gründen der Übersichtlichkeit lediglich vier Frontlängsträger dargestellt sind.To absorb impact energies acting on the front support structure in the event of frontal impact, six front side members are formed on the front support structure, of which, for reasons of overflow visibility only four front side members are shown.
Bei einem Frontalzusammenstoß verformen sich die Frontlängsträger und bilden Faltenbeulen aus, wodurch Aufprallenergie abgebaut wird. Dabei sind die Frontlängsträger so angeordnet, dass zwischen ihnen ein Gepäckraum ausgebildet werden kann.at a head-on collision deform the front side members and Form wrinkles, which dissipates impact energy. The front side members are arranged in such a way that between them a luggage room can be trained.

Die so ausgebildete Tragstruktur des Sportwagens weist im Fall eines Pfahlaufpralls eine hohe Energieabsorption auf, wobei eine Deformation der Fahrgastzelle vermieden werden kann. Dabei ist das Deformationselement, das zugleich die Aufnahme der Fahrzeugbatterie bildet, kostengünstig herzustellen.The so formed support structure of the sports car has in the case of a Pile impact on a high energy absorption, with a deformation the passenger compartment can be avoided. Here is the deformation element, at the same time forms the inclusion of the vehicle battery, inexpensive to manufacture.
