Abstract
Description
Die Erfindung bezieht sich auf eine Welle eines Kraftfahrzeugs, die zwischen einem Antriebsaggregat und, einer Antriebsachse angeordnet und über mindestens ein Karosserielager mit einer Karosserie verbunden ist.The invention relates to a Shaft of a motor vehicle between a drive unit and, arranged a drive axle and at least one body bearing connected to a body.
Es ist bereits eine Antriebsvorrichtung
für Kraftfahrzeuge

Aus der
Der Erfindung liegt die Aufgabe zugrunde, eine Kardanwelle derart auszubilden und anzuordnen, dass ein insassensicheres Ausknicken gewährleistet ist.The invention is based on the object Design and arrange propshaft in such a way that an occupant-safe Buckling guaranteed is.
Gelost wird die Aufgabe erfindungsgemäß dadurch, dass zwischen dem Karosserielager und der Karosserie, zwischen dem.The object is solved according to the invention by that between the body bearing and the bodywork, between the.
Karosserielager und der Welle und/oder zwischen der Welle und der Karosserie ein Sprengsatz angeordnet ist, durch den die Gelenkwelle nach dem Zünden eine mit Bezug zur Karosserie nach außen gerichtete plastische und/oder elastische Verformung aufweist. Hierdurch wird erreicht, dass die Welle nach dem Zünden des Sprengsatzes unter der gegebenen Axialkraft eine definierte Ausknickbewegung beschreibt, die zum einen eine Beschädigung der Karosserie bzw. eines Karosserietunnels verhindert und, zum anderen ein Verformungspotential für die durch den Aufprall entstehenden Verformungskräfte gewährleistet. Die Knautschzone des Kraftfahrzeugs wird somit durch die sich verformende Welle weitestgehend unterstützt. Durch das Lösen der mechanischen Verbindung zwischen der Welle und der Karosserie wird ein nachteiliger Einfluß der ausknickenden Gelenkwelle auf die Karosserie verhindert. Das Lager kann auch nur als Befestigungseinrichtung ausgebildet sein. Wenn die Gelenkwelle nach dem Zünden des Sprengsatzes eine mit Bezug zur Karosserie nach außen gerichtete plastische und/oder elastische Verformung bzw. eine Ausknickbewegung aufweißt, wird eine Beschädigung der Karosserie bzw. des Karosserietunnels verhindert. Die Gelenkwelle knickt nach außen aus und nimmt dabei noch Verformungsenergie auf bzw. gibt noch verformungsenergie an die Antriebsachse weiter.Body bearing and the shaft and / or between the shaft and the body an explosive device arranged is by which the PTO shaft after ignition one with respect to the bodywork directed to the outside having plastic and / or elastic deformation. This will Achieved that the shaft after igniting the explosive device the given axial force describes a defined buckling movement, the one for a damage prevents the body or a car body tunnel and, for other a deformation potential for the resulting from the impact Deformation forces guaranteed. The crumple zone of the motor vehicle is thus characterized by the deforming Wave largely supported. By loosening the mechanical connection between the shaft and the body becomes an adverse influence of kinking PTO shaft prevents the body. The warehouse can also be designed only as a fastening device. If the PTO shaft after ignition of the explosive device with respect to the body outward plastic and / or elastic deformation or a Ausknickbewegung welißt is a damage prevents the body or the body tunnel. The PTO shaft kinks to the outside and absorbs even deformation energy or gives even deformation energy to the drive axle on.
Zudem ist es vorteilhaft, dass der Sprengsatz an dem Karosserielager, an der Karosserie und/oder an der als Gelenkwelle ausgebildeten Welle angeordnet ist oder das Karosserielager einen Sprengsatz aufweist. Damit kann das Lösen des Karosserielagers bzw. der Ausknickimpuls der Gelenkwelle gewährleistet werden.Moreover, it is advantageous that the Explosive device on the body stock, on the body and / or on arranged as a propeller shaft shaft is arranged or Body bearing has an explosive device. Thus, the release of the Body bearing or the Ausknickimpuls the PTO shaft guaranteed become.
Eine zusätzliche Möglichkeit ist gemäß einer Weiterbildung, dass der Sprengsatz mit einer Airbag-Sensorik in Wirkverbindung steht. Die Zündung des Sprengsatzes ist somit nur bei gleichzeitigem Auslösen des Airbags gewährleistet. Eine separate Beschleuniqungssensorik ist nicht erforderlich.An additional possibility is according to a development, that the explosive device with an airbag sensor in operative connection stands. The ignition of the Explosive device is thus only at the same time triggering the Airbags guaranteed. A separate acceleration sensor is not required.
In Zusammenhang der erfindungsgemäßen Merkmale ist es vorteilhaft, dass die Gelenkwelle und das Karosserielager durch den Sprengsatz trennbar sind. Somit wird eine definierte Ausknickbewegung der Gelenkwelle gewährleistet.In connection of the features according to the invention It is advantageous that the PTO shaft and the body bearing be separated by the explosive device. Thus, a defined Ausknickbewegung the Drive shaft ensured.
Weitere Vorteile und Einzelheiten der Erfindung sind in den Patentansprüchen und in der Beschreibung erläutert und in den Figuren dargestellt.Further advantages and details The invention are in the claims and in the description explained and shown in the figures.
