Description
"An der Stirnwand einer selbsttragenden Kraftwagen-Karosserie unter Abkröpfung sich abstützender vorderer Längsträger""On the front wall of a self-supporting vehicle body with an offset supporting front longitudinal member "
Zusatz zu Patent ... (Patentanmeldung PAddendum to patent ... (patent application P.
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 Körper entsteht, und wobei jeder vordere Längsträger bei seinem Anlauf am formsteifen Körper eine Gabelung erfährt und die dabei entstehenden Arme den formsteifen Körper zumindest teilweise umfassen;nach Patent ... (Patentanmeldung P . . . ).The invention relates to a self-supporting one on the end wall Motor vehicle body under bend supporting itself front longitudinal member, wherein in the connection area of each front longitudinal member the end wall locally in the direction of the vehicle front is bulged in such a way that a rigid body is created, and each front longitudinal member When it comes up against the rigid body, it bifurcates and the resulting arms form the rigid body at least partially; according to patent ... (patent application P...).
In einen derart ausgesteiften Stirnwandbereich lassen sich über die einzelnen Arme hohe Kräfte großflächig einleiten, ohne daß es vorzeitig bei kleineren Gesamtdeformationen bereits zu Rückverschiebungen im Dereich der Stirnwand und des Pedalbodens kommt. Auch wird gleichzeitig eine Versteifung des vorderen Längsträgers im Dereich der Lenkungsbefestigung erreicht.In a front wall area reinforced in this way, high forces can be introduced over a large area via the individual arms, without prematurely shifting back in the area of the end wall and with smaller overall deformations of the pedal base comes. At the same time, there is also a stiffening of the front longitudinal member in the area of the steering attachment achieved.
Aufgabe der Erfindung ist es, in vorteilhafter Weiterbildung des beschriebenen Anschlußbereiches des vorderen Längs-The object of the invention is, in an advantageous further development the described connection area of the front longitudinal

trägers an der Stirnwand eine Lösung aufzuzeigen, die bei relativ einfachem Aufbau allen Anforderungen gerecht wird.to show a solution on the carrier on the front wall that meets all requirements with a relatively simple structure.
Deshalb wird eine Längsträgerabstützung der eingangs angeführten Art nach Patent ... (Patentanmeldung P ...) vorgeschlagen, wobei erfindungsgemäß durch die Gabelung vier Arme geschaffen werden, von denen die beiden unteren Arme - einen spitzen Winkel einschließend - zum Unterboden führen, und wobei die beiden oberen Arme im Dereich des formsteifen Körpers auslaufen.Therefore, a side member support of the type cited at the beginning is proposed according to patent ... (patent application P ...), with four arms according to the invention through the fork are created, of which the two lower arms - including an acute angle - lead to the sub-floor, and whereby the two upper arms terminate in the area of the rigid body.
Das gleiche Ziel wird auch dadurch erreicht, daß die Arme Teilflächen einer vorzugsweise nach der Sandwich-Bauart auf den formsteifen Körper aufgesetzten Kappe bilden, an die der vordere Längsträger anläuft.The same goal is also achieved in that the arms have partial surfaces, preferably according to the sandwich design Form the rigid body attached cap to which the front longitudinal member runs.
Eine weitere Erhöhung der Steifigkeit kann dadurch erreicht werden, daß jeder formsteife, seitlich bis zur Vorderwandsäule geführte Körper über eine angeformte Stützfläche mit dem Getriebetunnel und die Stützflächen untereinander verbunden werden.A further increase in rigidity can be achieved in that each dimensionally stable body, which is laterally guided up to the front wall column, has an integrally formed support surface the transmission tunnel and the support surfaces are connected to one another.
Von Vorteil ist es, wenn die obere Mantelfläche des formsteifen Körpers etwa parallel zur Lenkspindel verläuft und die Befestigung des Lenkungsrohres an der Innenseite der oberen Mantelfläche erfolgt. Bei einfacher Lenkspindelführung wird dabei die Größe des Fußraumes nur geringfügig reduziert.It is advantageous if the upper lateral surface of the rigid body runs approximately parallel to the steering spindle and the steering tube is attached to the inside of the upper lateral surface. With a simple steering spindle guide, the size of the footwell is only marginal reduced.
Bei einem bevorzugten AusfUhrungsbeispiel der Erfindung erhalten die Arme im Bereich des formsteifen Körpers durch dessen Wandung ein geschlossenes Trägerprofil.In a preferred embodiment of the invention, the arms get through in the area of the rigid body the wall of which is a closed support profile.

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 described in more detail below with the aid of an exemplary embodiment shown in the drawing explained. Show it
Fig. 1 eine Draufsicht auf einen - rfindungsgemäß ausgebildeten Anschlußbereich eines vorderen Längsträgers,Fig. 1 is a plan view of a - according to the invention designed connection area of a front longitudinal member,
Fig. 2 diesen Dereich in der Seitenansicht, und Fig. 3 eine Vorderansicht dieses Dereiches*Fig. 2 shows this area in a side view, and Fig. 3 shows a front view of this area *
Ein durch strichpunktierte Linien teilweise angedeuteter Personenkraftwagen weist zu beiden Seiten seiner Mittellängsachse 1 einen vorderen Längsträger 2 auf, der sich unter Abkröpfung an der Stirnwand 3 abstützt. Diese ist in diesem Bereich pyramidenstumpfförmig ausgebaucht und bildet dadurch einen formsteifen Körper h, der von vier, die Verlängerung des Längsträgers 2 bildenden/ aus einem oder mehreren Teilen bestehenden Armen 5»6,7 und 8 umgriffen wird. Hierdurch wird die Tragfähigkeit dieser sich seitlich an der Vorderwandsäule 16 abstützenden Stirnwandzone entscheidend verbessert.A passenger car partially indicated by dash-dotted lines has a front longitudinal member 2 on both sides of its central longitudinal axis 1, which is supported on the end wall 3 with an offset. This is bulged in the shape of a truncated pyramid in this area and thereby forms a dimensionally stable body h which is encompassed by four arms 5, 6, 7 and 8 which form the extension of the longitudinal beam 2 / consist of one or more parts. As a result, the load-bearing capacity of this end wall zone, which is supported laterally on the front wall pillar 16, is decisively improved.
Während die obenliegenden Arme 5 und 6 im Dereich des formsteifen Körpers 4 auslaufen, führen die beiden unteren Arme 7 und 8 über den formsteifen Körper k hinaus und schließen an Unterboden 9 an. Zur Mittellängsachse 1 hin weist jeder forasteife Körper k eine angeformte Stützfläche 10 auf, die an Getriebetunnel 11 anschließt. Die Stützflächen 10 sind zudem zur Erhöhung der Quersteifigkeit durch eine Strebe 12While the overhead arms 5 and 6 terminate in the area of the rigid body 4, the two lower arms 7 and 8 extend beyond the rigid body k and connect to the underbody 9. Towards the central longitudinal axis 1, each solid body k has an integrally formed support surface 10 which connects to the transmission tunnel 11. The support surfaces 10 are also provided with a strut 12 to increase the transverse rigidity

Wie insbesondere aus Fig. 2 ersichtlich, verläuft die obere Mantelfläche \h des formsteifen Körpers k etwa parallel zur angedeuteten Lenkspindel 15, deren nicht dargestelltes Mantelrohr dann auf einfache Weise festgelegt werden kann. Die beiden oberen Mantelflächen lh können auch einstückig miteinander verbunden sein, wobei das Verbindungsteil die Funktion der Strebe 12 übernimmt.As can be seen in particular from FIG. 2, the upper lateral surface \ h of the dimensionally stable body k runs approximately parallel to the indicated steering spindle 15, whose casing tube (not shown) can then be fixed in a simple manner. The two upper lateral surfaces 1h can also be connected to one another in one piece, the connecting part taking on the function of the strut 12.
