Abstract
Description
Die Erfindung betrifft eine Tragstruktur eines Kraftfahrzeugs mit einer Frontlängsträger aufweisenden Fronttragstruktur gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a support structure of a motor vehicle with a front support structure having front longitudinal members according to the generic term 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 supporting structure of the body of one Motor vehicle can in the front support structure, the floor support structure and the rear support structure can be divided. The Vehicle manufacturing the production of the entire supporting structure from aluminum, using sheet metal, extruded sections and castings.
Die Fronttragstruktur eines Kraftfahrzeugs weist in der Regel mindestens zwei Längsträger auf, die durch mindestens einen Querträger miteinander verbunden sind.The front support structure of a motor vehicle has usually at least two side members on the by at least one cross member are interconnected.
Einem Kraftfahrzeuge mit Mittelmotor oder Heckmotor steht bei einem Frontalzusammenstoß die Brennkraftmaschine als Blockbildungselement zur Energieabsorption nicht zur Verfügung.A mid-engine motor vehicle or the rear engine stops the engine in the event of a head-on collision not available as a block forming element for energy absorption.
Daraus entsteht die Notwendigkeit die Fronttragstruktur des Kraftfahrzeuges so auszugestalten, dass besonders viel Aufprallenergie absorbieren 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 beführten.This creates the need to design the front support structure of the motor vehicle in such a way that can absorb a lot of impact energy. Doing so in a motor vehicle with a rear engine, the space between the at least two front side members for Forming a trunk used. Especially in the event of a pole impact this means that deformations have to be carried into the passenger compartment.
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.The invention has for its object a Support structure of a motor vehicle with a front side member Front support structure according to the generic term it to specify claim 1, in which the front support structure is designed so that it is particularly high in the event of a pole impact Has energy absorption. The front support structure should be inexpensive to manufacture his.
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.This object is achieved by the Feature solved in the characterizing part of claim 1, according to which 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 further training the invention provides that on the at least one deformation element and on which at least one cross member molded parts are attached, which form a battery holder for mounting 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 one Coolant circuit for cooling the internal combustion engine. It is provided that as a further Deformation element a coolant line made of light metal 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 development of the The invention provides that the at least one cross member of the Wishbone suspension mount is used to attach a wishbone 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.It is provided that the internal combustion engine the motor vehicle is arranged in the rear that the chassis of the Motor vehicle is designed as a four-wheel drive, and that the motor vehicle as Sports car is trained.
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 The invention provides that the support structure of the motor vehicle is made of light metal, in particular aluminum.
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.Such a front support structure has even in the event of a pole impact, a high level of energy absorption occurs by the at least one arranged between the front side members, with the at least one a cross member connected deformation element a deformation up to 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.The following is the supporting structure according to the invention of a motor vehicle based on an embodiment in connection shown and explained with two figures.
Es zeigen:Show it:
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 energy, on frontal impacts the front support structure acting on the front support structure six front side members formed, of which for reasons the clarity 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.A head-on collision deforms the front side members and form wrinkles, which reduce the impact energy. The front side members are arranged so 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 support structure designed in this way of the sports car has a high energy absorption in the event of a pole impact on, whereby deformation of the passenger compartment can be avoided. Here is the deformation element, which is also the inclusion of the Vehicle battery forms, inexpensive manufacture.
