Inductive transformer for transmission of data and/or energy e.g. for automobile steering wheel, uses measurement of magnetic field for determining relative spacing of transformer cores

The inductive transformer, with integrated systems for simultaneous transmission of data and/or energy, has 2 transformer coils (1,2), each provided with a core (3,4), with the coils displaced relative to one another and the magnetic field between the transformer coils measured for determining their relative position, e.g. using a sensor (6) in the air-gap between the cores. The invention relates to an inductive translator composed of two spools (1, 2) with respective cores (3, 4), said cores (3, 4) being capable of moving in relation to each other. The translator comprises two integrated systems for a simultaneous transmission of data and/or energy as well as the position of the two cores (3, 4) relatively to each other. The transmission of data and/or energy finally takes place through induction and the determination of the relative position of the two cores (3, 4) is carried out by means of a measurement of the magnetic field prevailing between the two spools (1, 2). Die Erfindung betrifft einen induktiven Übertrager, bestehend aus zwei Spulen (1, 2) mit je einem Kern (3, 4). Die beiden Kerne (3, 4) sind hierbei relativ zueinander bewegbar. In den Übertrager sind zwei Systeme integriert, die eine gleichzeitige Übertragung von Daten und/oder Energie sowie von der Position der beiden Kerne (3, 4) zueiander ermöglichen. Schließlich erfolgt die Übertragung von Daten und/oder Energie mittels Iduktion und die Bestimmung der Position der beiden Kerne (3, 4) zueinander über eine Messung des zwischen den beiden Spulen (1, 2) herrschenden Magnetfeldes.
