CAPTEUR DE POSITION MAGNETIQUE DE FAIBLE COURSE, EN PARTICULIER DESTINE A LA MESURE DE TORSION D'UNE COLONNE DE DIRECTION

摘要

A position sensor, which can detect a steering column twist of a first magnetic rotoric structure including a plurality of radially oriented magnets and a second statoric structure including two concentric gear rings extended by radially oriented teeth. The rotoric structure is substantially disc-shaped and includes a ferromagnetic head supporting the plurality of magnets, the statoric structures are provided with interleaving teeth and the position sensor includes a third collector structure including two flow closing parts, one of which is fixed, and which define at least one air gap in which at least one magnetosensitive element is arranged.
