"An der Stirnwand einer selbsttragenden Kraftwagen-Karosserie unter Abkröpfung sich abstützender vorderer Längsträger""On the front wall of a self-supporting motor vehicle body with an offset that supports itself front longitudinal member "
Die Erfindung betrifft einen an der Stirnwand einer selbsttragenden Kraftwagen-Karosserie unter Abkröpfung sich abstützenden vorderen Längsträger, wobei im Anschlußbereich jedes vorderen Längsträgers die Stirnwand örtlich in Richtung des Fahrzeugbugs derart ausgebaucht ist, daß ein formsteifer Korper entsteht, und wobei jeder vordere Längsträger bei seinem Anlauf am formsteifen Körper eine Gabelung erfährt und die dabei entstehenden Arme den formstei fen Körper zumindest teilweise umfassen,nach Patent ... (Patentanmeldung P ...).The invention relates to a self-supporting one on the end wall Motor vehicle body with bend supporting front longitudinal member, with in the connection area of each front side member, the end wall is locally bulged in the direction of the vehicle front in such a way that a dimensionally stable Body arises, and each front longitudinal member experiences a fork when it approaches the rigid body and the resulting arms are the formstei fen At least partially embrace the body, according to the patent ... (patent application P ...).
Ein derartig ausgesteifter Stirnwandbereich weist den Vorteil auf, daß über die Arme hohe Kräfte großflächig eingeleitet werden können, ohne daß es vorzeitig zu Deformationserscheinungen im Dereich der Stirnwand und des Pedalbodens kommt.Such a stiffened end wall area has the advantage on that high forces can be introduced over a large area via the arms without premature deformation phenomena in the area of the end wall and the pedal base comes.
Es ist Aufgabe der Erfindung, in konsequenter Weiterführung dieses Gedankens eine Lösungsmöglichkeit aufzuzeigen, dieIt is the object of the invention to continue in a consistent manner this idea to show a possible solution that

bei 'geringen Kosten und unwesentlicher Gewichtserhöhung die auftretenden Kräfte sicher aufnehmen kann.at 'low costs and insignificant weight increase Can safely absorb occurring forces.
Deshalb wird eine Längsträgerabstutzung der eingangs genannten Art nach Patent ... (Patentanmeldung P ...) vorgeschlagen, wobei erfindungsgemäß durch die Gabelung zwei Arme geschaffen werden, die zueinander parallel oder winklig verlaufend zum Unterboden führen.Therefore, a side member support is the one mentioned at the beginning Art proposed by patent ... (patent application P ...), whereby, according to the invention, two arms are created by the fork that run parallel or at an angle to each other and lead to the sub-floor.
Zur weiteren Aussteifung können die Enden der Arme durch mindestens einen auf dem Unterboden aufgesetzten oder aus diesem herausgeformten und in Fahrzeugquerrichtung verlaufenden Träger verbunden sein.For further stiffening, the ends of the arms can be fitted with or removed from at least one be connected to this formed and extending in the vehicle transverse direction carrier.
Dei einem bevorzugten Ausführungsbeispiel der Erfindung werden die Arme durch Eindrückungen im formsteifen Körper gebildet und durch ein Deckblech geschlossen.In a preferred embodiment of the invention the arms are formed by indentations in the rigid body and closed by a cover plate.
Es ist aber auch möglich, daß die Arme zusammen mit dem ihre freien Enden verbindenden Träger einen vorgefertigten, aufsetzbaren Trägerverband bilden, an dem der zugeordnete Längsträger angeschlossen wird.But it is also possible that the arms, together with the carrier connecting their free ends, have a prefabricated, attachable Form girder association to which the associated longitudinal girder is connected.
Der Gegenstand der Erfindung soll nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert werden. Es zeigenThe subject matter of the invention is to be explained in more detail below with reference to an exemplary embodiment shown in the drawing will. Show it

Ein beiderseits der Mittellängsachse 1 (Fig. 2) einer nicht näher dargestellten selbsttragenden Kraftwagen-Karosserie durch örtliche Ausbauchung der Stirnwand 2 geschaffener formsteifer Körper 3 nimmt unter Abkröpfung einen vorderen Längsträger 4 auf, der vor seinem Anlauf sich in zwei Arme 5 und aufteilt. Diese verlaufen zueinander winklig und schließen am Unterboden 7 an und können z.B. aus den Wandungen des formsteifen Körpers 3 herausgeformt und durch ein Deckblech geschlossen sein.One on both sides of the central longitudinal axis 1 (Fig. 2) of a self-supporting motor vehicle body, not shown in detail dimensionally stable created by local bulging of the end wall 2 Body 3 takes on a front longitudinal member 4 with a bend, which before its approach into two arms 5 and divides. These run at an angle to each other and connect to the sub-floor 7 and can, for example, consist of the walls of the rigid body 3 formed out and closed by a cover plate.
Mindestens ein die freien Enden der Arme 5 und 6 verbindender, in Fahrzeugquerrichtung verlaufender Träger 8 erbringt eine zusätzlich versteifende Wirkung, so daß-wie Versuche gezeigt haben - die Dlechdicke des so entstehenden Trägerverbandes geringer sein kann als die Dicke des Längsträgers k. At least one beam 8 connecting the free ends of the arms 5 and 6 and running in the transverse direction of the vehicle produces an additional stiffening effect, so that - as tests have shown - the sheet thickness of the resulting beam structure can be less than the thickness of the side member k.
