Abstract

The method involves using a transmission path containing two coils for energy and data transmission that are mounted so as to be rotatable wrt. each other. One coil consists of halves and at least one of the halves has an L-shaped cross-section. The halves are preferably. made of a weakly magnetic material (e.g. ferrite or a material with comparable properties).

Description

Bekannte Verfahren sind [a] Schleifringe sowie [b] induktive Übertragung mit zwei Schallenkernhälften.Known methods are [a] slip rings and [b] inductive transmission with two halves of the sound core.

Nachteiledisadvantage

Zu [a]: Mechanischer Verschleiß bei hohen Beschleunigungen können die Kontaktstellen unterbrochen werden.To [a]: Mechanical wear the contact points can be interrupted at high accelerations.

Zu [b]: mechanisch Versatz der Schallenkernhälften in axialer als auch radialer Richtung verändern die Kopplung der Übertragungsstelle und somit den Wirkungsgrad.To [b]: mechanical misalignment of the sound core halves in the axial and radial direction change the Coupling the transfer point and thus the efficiency.

In der Offenlegungsschrift DE 195 32 296 A1 wird ein Verfahren beschrieben welches diese Nachteile nicht aufweist. Nachteilig bei dieser Lösung, gegenüber dem Erfindungsanspruch, ist die aufwendige Form und der Platzbedarf des Schallenkerns.The published patent application DE 195 32 296 A1 describes a method which has these disadvantages does not have. A disadvantage of this solution compared to the claim of the invention is the complex Shape and space requirements of the sound core.

Diese Nachteile werden durch die Erfindung behoben.These disadvantages are eliminated by the invention.
