Abstract
Description
Die Erfindung betrifft eine Fahrzeugkarosserie mit wenigstens einem Längsträger, der in dem Frontbereich der Fahrzeugkarosserie wenigstens annähernd parallel zu einer Längsachse der Fahrzeugkarosserie angeordnet ist.The invention relates to a vehicle body having at least one longitudinal member, which is arranged in the front region of the vehicle body at least approximately parallel to a longitudinal axis of the vehicle body.
Derartige Längsträger dienen insbesondere dazu, bei einer Frontalkollision eines Fahrzeugs mit einem anderen Objekt die Aufprallenergie teilweise zu absorbieren, indem ein Teil der Aufprallenergie zur Deformierung der Längsträger verbraucht wird. Dadurch werden die auf Fahrzeuginsassen wirkende Aufprallwucht sowie ein Verletzungsrisiko für die Fahrzeuginsassen verringert.Such longitudinal members are used in particular to partially absorb the impact energy in a head-on collision of a vehicle with another object by a part of the impact energy is consumed to deform the side members. As a result, the impact force acting on vehicle occupants and a risk of injury to the vehicle occupants are reduced.
Diese Schutzfunktion der Längsträger bleibt jedoch weitgehend wirkungslos, wenn bei einer Frontalkollision nur ein Teilbereich der Fahrzeugfront, in dem sich kein Längsträger befindet, mit einem Objekt kollidiert. insbesondere ist dies bei Frontalkollisionen mit Objekten in Seitenbereichen der Fahrzeugfront der Fall, da Längsträger in der Regel nicht in diesen Seitenbereichen angeordnet sind.However, this protective function of the longitudinal members remains largely ineffective if, in a frontal collision, only a portion of the vehicle front, in which no longitudinal member is located, collides with an object. In particular, this is the case in frontal collisions with objects in side areas of the vehicle front, since side members are generally not arranged in these side areas.
Der Erfindung liegt die Aufgabe zu Grunde, eine Fahrzeugkarosserie mit wenigstens einem Längsträger anzugeben, die einen verbesserten Fahrzeuginsassenschutz bei Frontalkollisionen ermöglicht.The invention is based on the object to provide a vehicle body with at least one side member, which allows improved vehicle occupant protection in frontal collisions.
Die Aufgabe wird erfindungsgemäß durch eine Fahrzeugkarosserie mit den Merkmalen des Anspruchs 1 gelöst.The object is achieved by a vehicle body with the features of
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Eine erfindungsgemäße Fahrzeugkarosserie weist wenigstens einen Längsträger auf, der in dem Frontbereich der Fahrzeugkarosserie wenigstens annähernd parallel zu einer Längsachse der Fahrzeugkarosserie angeordnet ist und durch eine Seilkonstruktion an wenigstens einen Seitenbereich des Frontbereichs der Fahrzeugkarosserie gekoppelt ist. Dabei ist die Seilkonstruktion derart ausgebildet, dass eine Aufprallkraft, die parallel zu der Längsachse der Fahrzeugkarosserie in Richtung des Heckbereichs der Fahrzeugkarosserie auf den Seitenbereich einwirkt, eine Zugkraft auf den Längsträger bewirkt, die eine zu der Längsachse der Fahrzeugkarosserie orthogonale Zugkraftkomponente aufweist.A vehicle body according to the invention has at least one longitudinal carrier which is arranged in the front region of the vehicle body at least approximately parallel to a longitudinal axis of the vehicle body and is coupled by a cable construction to at least one side region of the front region of the vehicle body. In this case, the cable construction is designed such that an impact force, which acts parallel to the longitudinal axis of the vehicle body in the direction of the rear region of the vehicle body on the side region, causes a tensile force on the side member having an orthogonal to the longitudinal axis of the vehicle body traction component.
Bei einer Frontalkollision eines Fahrzeugs, das eine erfindungsgemäße Fahrzeugkarosserie aufweist, wird eine Aufprallkraft, die auf einen Seitenbereich des Frontbereichs der Fahrzeugkarosserie einwirkt, durch die Seilkonstruktion teilweise auf einen Längsträger der Fahrzeugkarosserie umgelenkt, so dass auf diesen Längsträger eine Zugkraft mit einer zu der Längsachse der Fahrzeugkarosserie orthogonalen Zugkraftkomponente wirkt. Diese Zugkraftkomponente kann einerseits eine Verbiegung des Längsträgers bewirken und andererseits ein Drehmoment erzeugen, welches das Fahrzeug in eine Rotation um seine Hochachse versetzt. Dadurch kann ein Teil der Aufprallenergie in eine Verbiegung des Längsträgers absorbiert und/oder in Rotationsenergie umgewandelt werden.In a head-on collision of a vehicle having a vehicle body according to the invention, an impact force acting on a side region of the front region of the vehicle body, partially deflected by the cable construction on a side member of the vehicle body, so that on this side member a tensile force with a to the longitudinal axis of Vehicle body orthogonal traction component acts. This tensile force component can on the one hand cause bending of the longitudinal member and on the other hand generate a torque which puts the vehicle in a rotation about its vertical axis. As a result, part of the impact energy can be absorbed in a bending of the longitudinal member and / or converted into rotational energy.
Dabei wird ein Längsträger durch die Seilkonstruktion auch dann in die Absorption der Aufprallenergie einbezogen, wenn die eigentliche Kollision nur in einem Seitenbereich der Fahrzeugfront erfolgt, in dem gar kein Längsträger angeordnet ist. Die Längsträger tragen also auch bei einer solchen Frontalkollision vorteilhaft zum Schutz der Fahrzeuginsassen bei.In this case, a longitudinal member is included by the rope construction in the absorption of the impact energy even if the actual collision takes place only in a side region of the vehicle front, in which no longitudinal member is arranged. The side members thus also contribute to such a frontal collision advantageous for the protection of the vehicle occupants.
Ein weiterer Vorteil der Erfindung liegt darin, dass die Seilkonstruktion nur sehr wenig zusätzlichen Bauraum erfordert und das Gewicht der Fahrzeugkarosserie nur unwesentlich erhöht. Dies ist vorteilhaft gegenüber Fahrzeugkarosserien, die zu einem entsprechenden Schutz der Fahrzeuginsassen zusätzliche Struktur- oder Versteifungselemente aufweisen, die mehr Bauraum einnehmen und das Gewicht der Fahrzeugkarosserie deutlicher erhöhen. Die Erfindung erhöht somit bei nur geringem Bauraumbedarf und einer unwesentlichen Gewichtserhöhung die Schutzwirkung der Fahrzeugkarosserie erheblich gegenüber einer Fahrzeugkarosserie, die nur den wenigstens einen Längsträger, aber keine erfindungsgemäße Seilkonstruktion aufweist.Another advantage of the invention is that the cable construction requires very little additional space and increases the weight of the vehicle body only insignificantly. This is advantageous over vehicle bodies, which have additional structural or stiffening elements for a corresponding protection of the vehicle occupants, take up more space and increase the weight of the vehicle body more clearly. The invention thus significantly increases the protective effect of the vehicle body compared to a vehicle body, which has only the at least one longitudinal beam, but no inventive cable construction with only a small space requirement and a negligible increase in weight.
