Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Abstützung der über einen Stoßfänger eingeleiteten Kräfte, mit einem aus einem ein stückigen Profilabschnitt bestehenden, insbesondere vorderen Querträger, der - endseitig mit Überstand - zwei Fahrzeuglängs träger miteinander verbindet.The invention relates to a device for supporting the a bumper initiated forces, with one out of one lumpy profile section existing, especially front Cross member, which - at the end with a projection - two vehicle lengthways connects carrier with each other.
Ein derartiger Querträger, der aus einem kleinvolumigen Profil abschnitt besteht und der gegenüber herkömmlichen, aus zwei relativ voluminösen Blechhalbschalen zusammengesetzten Quer trägern wenig Bauraum benötigt, ist durch die DE-OS 19 02 391 bekannt. Vor seinem Anlauf an den Querträger spaltet sich jeder vordere Längsträger in zwei gegenläufige Trägeräste auf, wo durch wohl eine günstige Krafteinleitung in die Längsträger erreicht wird, jedoch viel Platz verlorengeht, der gerade in diesem Vorbaubereich wegen der dort massiert untergebrachten Aggregate dringend benötigt wird.Such a cross member made of a small volume profile section consists of and compared to conventional, of two relatively voluminous half-shell composite cross carriers require little installation space, is by DE-OS 19 02 391 known. Before he starts on the cross member, everyone splits front side members in two opposite carrier branches on where by probably a cheap introduction of force into the side members is achieved, but a lot of space is lost that is currently in this stem area because of the massaged there Aggregates is urgently needed.
Es ist Aufgabe der Erfindung, eine leicht an unterschiedliche Bedürfnisse anpaßbare Querträgerausbildung zu schaffen, die einfach in einen Trägerverband eingliederbar ist, wobei trotz geringer Bauraumbeanspruchung große Kräfte aufgenommen und ab geleitet werden können.It is an object of the invention, a slightly different To create customizable cross member training needs is easy to incorporate into a supporting association, despite small space requirements take up and take off large forces can be directed.
Diese Aufgabe wird bei einer Vorrichtung zur Abstützung der über einen Stoßfänger eingeleiteten Kräfte gemäß dem Oberbe griff des Patenanspruches 1 durch dessen kennzeichnende Merk male gelöst.This object is achieved in a device for supporting the forces introduced via a bumper in accordance with the Oberbe attacked the patent claim 1 by its characteristic note times solved.
Bei einem Ausführungsbeispiel der Erfindung erfolgt die Quer trägerfestlegung, indem die Platte durch Punkt- oder Buckel schweißen mit den Flanschen verbunden wird. Es ist aber auch möglich, die Platte durch Schraubverbindungen mit den Flanschen zu verbinden. Diese Schraubverbindungen können gleichzeitig dazu verwendet werden, einen vorgeschalteten, über elastische Halter abstützbaren Stoßfänger, aufzunehmen.In one embodiment of the invention, the cross takes place Beam fixing by the plate by point or hump welding is connected to the flanges. It is also possible to screw the plate with the flanges connect to. These screw connections can be made simultaneously to be used upstream, over elastic Supportable bumper to accommodate.
Insbesondere bei mehreren, übereinander angeordneten Querträ gern ist es zum Erhalt einer großflächigen Abstützbasis für dem Stoßfänger zugeordnete Schaumstoffabsorber zweckmäßig, beide Platten über ein Zwischenstück miteinander zu verbinden.Especially with several cross beams arranged one above the other It is a pleasure to maintain a large support base for the Foam absorbers assigned to bumpers are useful, both To connect panels with each other via an intermediate piece.
Die Festlegung des Zwischenstückes kann durch die Querträger zumindest teilweise umfassende Halter nach Art einer Rohr schelle erfolgen.The crosspiece can be used to define the intermediate piece at least partially comprehensive holder in the manner of a tube done quickly.
In weiterer Ausgestaltung der Erfindung kann das Zwischenstück einen Durchbruch aufweisen und die Querträger können unter Aus bauchung um den Durchbruch herumgeführt sein.In a further embodiment of the invention, the intermediate piece have a breakthrough and the cross beams can under off belly around the breakthrough.
Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung näher erläutert.An embodiment of the invention is described below the drawing explained in more detail.
Ein rechtsseitiger vorderer Fahrzeuglängsträger 1, dem im Ab stand ein linksseitiger, nicht dargestellter weiterer Fahr zeuglängsträger zugeordnet ist, weist Ausnehmungen 2 zur Auf nahme zweier aus hochfestem Profilmaterial bestehender Quer träger 3 auf, die in nicht dargestellter Weise über die gesamte Fahrzeugfront reichen. Stirnseitig des Fahrzeuglängsträgers 1 sind Flansche 4 abgestellt, an denen eine durch Buckelschweißverbindungen 5 mit den Querträgern 3 verbundene Platte 6 sich abstützt, die aus einem Blechteil oder Gußteil, insbesondre Leichtmetallgußteil bestehen kann. Durch Punkt- oder Buckelschweißverbindungen 7 ist die Platte 6, den Fahr zeuglängsträger 1 nach vorn hin abschließend, an den Flanschen 4 befestigt. Bohrungen 8, die sowohl die Platte 6 ober- und un terseitig als auch den oberen und unteren Flansch 4 durchset zen, dienen der Aufnahme von nicht dargestellten Schraubver bindungen, mittels denen eine zusätzliche bzw. ausschließliche Verbindung zwischen diesen Flanschen 4 und der Platte 6 er folgt.A right-hand front vehicle side member 1 , which stood in the From left-hand side, not shown, other vehicle side member has recesses 2 for receiving two cross members 3 made of high-strength profile material, which extend in a manner not shown over the entire vehicle front. On the front side of the vehicle side member 1 are flanges 4 , on which a plate 6 , which is connected by hump welding connections 5 to the cross members 3 , is supported, which can consist of a sheet metal part or casting, in particular light metal casting. By spot or hump weld connections 7 , the plate 6 , the vehicle longitudinal member 1 in conclusion towards the front, attached to the flanges 4 . Holes 8 , both the plate 6 on the upper and lower side and the upper and lower flange 4 , serve to accommodate screw connections, not shown, by means of which an additional or exclusive connection between these flanges 4 and the plate 6 is used follows.
Mittels dieser Schraubverbindungen können in gleichfalls nicht gezeigter Weise elastisch deformierbare Halter eines vorge schalteten Stoßfängers festgelegt werden. Um eine gute Ab stützbasis für den Stoßfänger zugeordnete Schaumstoff-Ener gieabsorber zu schaffen, ist der besonders aufprallgefährdete Bereich zwischen den beiden Platten 6 durch ein Zwischenstück 9 abgedeckt, das über die Querträger 3 teilweise umfassende Hal ter 10 in Form von Rohrschellen, von denen nur einer ersicht lich ist, festgelegt ist.By means of these screw connections, elastically deformable holders of an upstream bumper can also be fixed in a manner not shown. In order to create a good support base for the bumper-associated foam energy absorber, the particularly impact-prone area between the two plates 6 is covered by an intermediate piece 9, which, in part in the form of pipe clamps, only partially includes the cross member 3 and the hal ter 10 one is obvious, is fixed.
Wie angedeutet, ist das Zwischenstück 9 mit einem Durchbruch 11 versehen und die Querträger 3 sind ausgebaucht um diesen Durch bruch 11 herumgeführt, so daß beim Vorsehen einer zugeordneten Öffnung im vorgeschalteten, nicht dargestellten Stoßfänger Kühlluft gezielt zugeführt werden kann.As indicated, the intermediate piece 9 is provided with an opening 11 and the cross members 3 are bulged around this opening 11 , so that cooling air can be supplied in a targeted manner if an associated opening is provided in the upstream bumper, not shown.
