- einer Spulenanordnung und- a coil arrangement and
- einem Gleitkernelement,- a sliding core element,
die jeweils an einem der Teilelemente angeordnet sind.which are each arranged on one of the sub-elements.
Um eine Drehbewegung eines sich bewegenden Teilelementes erfassen zu können, ist aus DE 88 15 685 Ul bekannt, ein Gleitkernelement auf einer Scheibe anzuordnen, der sich gegenüber einer Spulenanordnung befindet. Auch wenn sich diese Anordnung bewährt hat, ist eine Stellung des Kernelements hierdurch nicht genau erkennbar.In order to be able to detect a rotary movement of a moving sub-element, it is known from DE 88 15 685 Ul to arrange a sliding core element on a disk that is located opposite a coil arrangement. Even if this arrangement has proven itself, the position of the core element cannot be precisely determined.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß die Spulenanordnung aus einem zentral liegenden Speisespulen-According to the invention, the object is achieved in that the coil arrangement consists of a centrally located supply coil
element und wenigstens zwei um dieses gruppierte Empfangsspulenelemente besteht, und daß das Gleitkernelement über dem Speisespulenelement und den Empfangsspulenelementen bewegbar ist, so daß durch eine Bewegung des Gleitkernelements in einer Gleitkernperipherie eine Stellung und eine Bewegungsrichtung feststellbar ist.element and at least two receiving coil elements grouped around it, and that the sliding core element is movable over the feed coil element and the receiving coil elements, so that a position and a direction of movement can be determined by a movement of the sliding core element in a sliding core periphery.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere in einer komplexen Erfassung von Stellung und Bewegungsrichtung innerhalb eines zweidimensionalen Feldes derart, daß in jeder Endstellung eines Meßbereiches sowohl die jeweils außenliegende Empfängerspule und die Speisespule vollständig überdeckt werden. Meßwertstreuungen, die auf ein mechanisches Spiel senkrecht zur 15The advantages achieved with the invention consist in particular in a complex detection of position and direction of movement within a two-dimensional field in such a way that in each end position of a measuring range both the respective external receiver coil and the feed coil are completely covered. Measurement value scatter which is due to mechanical play perpendicular to the 15

Eine zweidimensionale Bewegung wird genau erfaßt und steht zu einer Auswertung zur Verfügung.The sliding core prevents errors that go back to the plane of movement of the parts moving relative to each other. A two-dimensional movement is recorded precisely and is available for evaluation.
Vorteilhaft ist es, wenn vier Empfangsspulenelemente kreuzförmig in einem im wesentlichen gleichen Abstand gegenüber dem Speisespulenelement angeordnet sind. Hierdurch ist es möglich, daß der sich über der Empfängerspulengruppe bewegende Gleitkern in jeder EndstellungIt is advantageous if four receiving coil elements are arranged in a cross shape at a substantially equal distance from the feed coil element. This makes it possible for the sliding core moving over the receiving coil group to be in each end position

Auf diese Weise läßt sich aus den Empfängerspulenpaaren ein von der anderen Bewegungsrichtung nahezu unbeeinflußtes Stellungssignal auslösen. the external receiver coil and the feeder coil can be completely covered. In this way, a position signal can be triggered from the receiver coil pairs that is almost unaffected by the other direction of movement.
Vorteilhaft ist es, wenn das Speisespulenelement und die Empfängerspulenelemente in einer ebenen, einer gebogenen oder einer kugelförmigen Flächenkonfiguration angeordnetIt is advantageous if the feed coil element and the receiver coil elements are arranged in a flat, curved or spherical surface configuration.

Vorteilhaft ist es, wenn das Speisespulenelement und die Empfangsspulenkernelemente mit einer Versorgungs- und Auswerteeinheit verbunden sind. Hierdurch ist es möglich, die empfangenen Meßwerte zu erzeugen, zu erfassen und mit ausreichender Genauigkeit auswerten zu können.It is advantageous if the feed coil element and the receiving coil core elements are connected to a supply and evaluation unit. This makes it possible to generate, record and evaluate the received measurement values with sufficient accuracy.

Hierdurch ist es möglich, anhand der Getriebestellung erkennen zu können, wann ein Einlegen eines Ganges mit einer vollen Kraftübertragung von einer Antriebseinheit, z. B. einem Motor, möglich ist* Vorteilhafterweise ermöglicht das weichmagnatische Gleitkernelement die stellungsabhängige Einkopplung des Magnetflusses durch eine variable Überlappung der Empfangsspulenelemente.This makes it possible to use the gear position to determine when a gear can be engaged with a full power transmission from a drive unit, e.g. a motor* Advantageously, the soft magnetic sliding core element enables the position-dependent coupling of the magnetic flux through a variable overlap of the receiving coil elements.
