Abstract (de)

Die Erfindung betrifft einen induktiven Übertrager zur Übertragung von Messdaten und/oder elektrischer Energie zwischen zwei gegeneinander beweglichen Bauteilen mit einem primären und einem sekundären Übertragerteil (13,15), insbesondere zwischen an der Lenkspindel (11)und der Lenksäule (10) eines Fahrzeuges. Im Bereich zwischen dem primären und dem sekundären Übertragerteil (13,15) ist ein flexibles oder gleitendes ferromagnetisches Material (17;20) angebracht. Das flexible ferromagnetische Material kann eine Schürze (17) sein, die den Spalt zwischen dem primären und dem sekundären Übertragerteil (13,15) nahezu vollständig umschließt oder eine Lagerschale (20), an der das primäre und/oder das sekundäre Übertragerteil (13,15) gleitend führbar ist. <IMAGE>
