Method for acquiring the rotary and translational movement of main switching shaft e.g. of motor vehicle transmission using permanent magnets and linear inductive contactless position sensor

摘要

The method involves providing the main switching shaft of the transmission with at least one permanent magnet and a linear inductive contactless position sensor which is arranged nor far from the shaft which is controlled by the magnet. The shaft (1) is divided in its axial direction into several linear sections and the permanent magnet (2,4) is sub-divided and assigned to every linear section and fastened to the outside of the shaft. The permanent magnets are staggered radially to each other and also have the same measurements. An Independent claim is included for the rotary and translational movement acquiring device implementing the above method.
