Abstract

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.

The invention relates to an inductive transmitter for the transmission of measurement data and / or electrical energy between two mutually movable components with a primary and a secondary transmitter part (13, 15), in particular between the steering spindle (11) and the steering column (10) of a vehicle. A flexible or sliding ferromagnetic material (17; 20) is attached in the area between the primary and the secondary transmitter part (13, 15). The flexible ferromagnetic material can be an apron (17) which almost completely encloses the gap between the primary and the secondary transmitter part (13, 15) or a bearing shell (20) on which the primary and / or the secondary transmitter part (13, 15) is slidable.
