Title (EN) STEERING SHAFT
(FR) ARBRE DE DIRECTION
(DE) LENKSPINDEL
Abstract:
(EN) A steering shaft (1) has a thin-walled container (5) which is filled with an incompressible, flowable material (7). In the event of a collision, said container (5) is opened with an e.g. pyrotechnical device (13). The flowable material (7) then emerges and the container (5) deforms. This separates the intrusion at the front end of the vehicle from the behavior of the steering column.
(FR) La présente invention concerne un arbre de direction (1) présentant un tube collecteur (5) à parois fines rempli d'un fluide non compressible (7). En cas de collision, le tube collecteur (5) est ouvert au moyen, par exemple, d'un dispositif pyrotechnique (13). Cela provoque la fuite du fluide (7) et la déformation du tube collecteur (5), grâce auxquelles l'intrusion à l'avant du véhicule et le comportement de la colonne de direction ne sont plus liés.
(DE) Eine Lenkspindel (1) weist einen dünnwandigen Behälter (5) auf, der mit einem inkompressiblen, fliessfähigen Material (7) gefüllt ist. Der Behälter (5) wird im Crashfall mit einer beispielsweise pyrotechnischen Einrichtung (13) geöffnet. Damit tritt das fliessfähige Material (7) aus und der Behälter (5) verformt sich, wodurch die Vorderwagenintrusion vom Lenksäulenverhalten entkoppelt wird.
