Abstract
In a measuring device for the non-contact detection of the absolute angle of rotation of a shaft, such as a steering column, at multiple revolutions, magnetic, optical or magneto-optical structures are arranged on the shaft or a part connected therewith. The shaft carries a thread which is in engagement with a rider or index finger. At least one sensor is provided to detect the magnetic, optical or magneto-optical structures as well as the displaced position of the rider or index finger.
Claims15
A measuring device provided in a shaft arrangement including a shaft means, such as a steering column, for the non-contact detection of the absolute angle of rotation of said shaft means at multiple revolutions, which measuring device comprises
- a plurality of magnetic, optical or magneto-optical structural means arranged on said shaft means,
- a rider or index finger capable of being displaced in the axial direction of said shaft means into a displaced position,
- a shaft means thread provided on said shaft means for engagement with said rider or index finger, and
- at least one sensor means arranged to detect said plurality of magnetic, optical or magneto-optical structural means as well as said displaced position of said rider or index finger.
