Description
Die Erfindung betrifft eine Anordnung eines querliegenden Antriebsaggregats im Vorbau eines Kraftfahrzeugs, der von einer Fahrgastzelle durch eine Stirnwand getrennt ist.The invention relates to an arrangement a transverse drive unit in the stem of a motor vehicle, which is separated from a passenger compartment by an end wall.
Bei derartigen Kraftfahrzeugen besteht die Gefahr, daß das im wesentlichen unverformbare Antriebsaggregat im Falle eines Frontalaufpralls die Stirnwand durchstößt und in die Fahrgastzelle eindringt. Es sind deswegen verschiedene Ansätze entwickelt worden, die darauf abzielen, eine solche Horizontalbewegung des Kraftfahrzeugs im Falle eines Frontalaufpralls zu vermeiden. Den bekannten Ansätzen ist gemein, daß das Antriebsaggregat bei einem Frontalaufprall zu einer schräg nach unten gerichteten Bewegung gezwungen wird.In such motor vehicles the danger that that essentially non-deformable drive unit in the event of a frontal impact the front wall pierces and in the passenger compartment penetrates. There are therefore different approaches developed been aimed at such a horizontal movement of the Motor vehicle in the event of a frontal collision to avoid. The known approaches is common that the Drive unit in a frontal impact to an obliquely downward directed movement is forced.

Es stellt sich deswegen die Aufgabe, eine gattungsgemäße Anordnung anzugeben, bei der das Antriebsaggregat die Stirnwand selbst dann nicht durchdringt, wenn das Antriebsaggregat vor der Vorderachse des Kraftfahrzeugs angeordnet ist. Die Gewährleistung der Sicherheit soll außerdem nicht von der Wahl spezieller Abmessungen des Antriebsaggregats abhängen.It is therefore the task a generic arrangement specify where the drive unit the end wall even then does not penetrate when the drive unit in front of the front axle of the motor vehicle is arranged. Ensuring safety should in addition not on the choice of special dimensions of the drive unit depend.
Die Erfindung löst diese Aufgabe durch eine Anordnung nach Anspruch 1. Bei dieser Anordnung ist im Vorbau zwischen dem Antriebsaggregat und der Stirnwand ein Querträger angeordnet. Ferner ist das Antriebsaggregat so im Vorbau befestigt, daß bei einem Frontalaufprall des Kraftfahrzeugs das Antriebsaggregat sich zumindest teilweise von den Befestigungen löst und eine zur Unterseite der Fahrgastzelle hin gerichtete Schwenkbewegung um den Querträger herum ausführt. Der Querträger hat somit eine Doppelfunktion. Zum einen schützt er unmittelbar die Fahrgastzelle vor dem Eindringen des Antriebsaggregats. Durch seine Lage zwischen dem Antriebsaggregat und der Stirnwand bewirkt der Querträger ferner, daß im Falle eines Frontalaufpralls das Antriebsaggregat durch Anschlag oder Anliegen am Querträger ein Drehmoment er fährt, das zu einer nach unten hin gerichteten Schwenkbewegung des Antriebsaggregats führt. Durch das Wegschwenken des Antriebsaggregats wird zusätzlicher Deformationsweg im Vorbau freigegeben.The invention solves this problem by an arrangement according to claim 1. In this arrangement is in the stem between the drive unit and the end wall a cross member arranged. Furthermore, the drive unit is mounted in the stem, that at one Frontal impact of the motor vehicle, the drive unit at least partially detached from the fixtures and one to the bottom the passenger cell directed towards the pivoting movement around the cross member performs. The crossbeam thus has a double function. First, it directly protects the passenger compartment before the penetration of the drive unit. Due to its location between the drive unit and the end wall causes the cross member further, that in the In case of a frontal collision, the drive unit by stop or concerns on the cross member a torque he drives, this leads to a downwardly directed pivoting movement of the drive unit leads. By pivoting away the drive unit is additional Deformation path in the stem released.
Damit das Antriebsaggregat in der
gewünschten
Weise bei einem Frontalaufprall nach unten zur Unterseite der Fahrgastzelle
hin schwenkt, muß sich
der Schwerpunkt des Antriebsaggregats spätestens zum Zeitpunkt des Anschlags
am Querträger
unterhalb des Querträgers
befinden. Andernfalls würde
das Antriebsaggregat eine Schwenkbewegung nach oben über den
Querträger
hinweg ausführen.
Bei einer vorteilhaften Ausgestaltung nach Anspruch 2 wird diese
Bedingung dadurch gewährleistet,
daß der
Querträger
oberhalb des Schwerpunktes des Antriebsaggregats im Vorbau angeordnet
ist und/oder nach Anspruch 3 oberhalb einer vorgesehenen Krafteinleitung
(in Richtung Pfeil
Bei einer vorteilhaften Ausgestaltung nach Anspruch 3 ist der Querträger Teil der Stirnwand. Im Vergleich zu einem separaten Querträger läßt sich auf diese Weise eine deutliche Gewichtsredution erzielen.In an advantageous embodiment according to claim 3, the cross member Part of the front wall. Compared to a separate cross member can be on achieve a clear weight reduction this way.
Bei einer weiteren Ausgestaltung nach Anspruch 4 wird das Antriebsaggregat in an sich bekannter Weise von einem sich zwischen Längsträgern des Kraftfahrzeugs erstreckenden Integralträger getragen. Der Integralträger ist erfindungsgemäß so ausgeführt, daß er bei einem Frontalaufprall des Kraftfahrzeugs durch Deformation oder (Soll-)Bruch den Weg für die gewünschte Schwenkbewegung des Antriebsaggregats freigibt. Die Verwendung eines Integralträgers ist vor allem zweckmäßig im Hinblick auf eine leichte Montierbarkeit des Kraftfahrzeugs.In a further embodiment according to claim 4, the drive unit in a conventional manner from one itself between longitudinal beams of the Car vehicle extending integral support worn. The integral carrier is According to the invention designed so that it a frontal impact of the motor vehicle by deformation or (Soll-) break the way for the desired Swivel movement of the drive unit releases. The use of a integral carrier is especially useful in terms of an easy mountability of the motor vehicle.
Ein vorteilhaftes Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnungen erläutert, von denen zeigen:An advantageous embodiment The invention is explained below with reference to the drawings, of show:
