Title (EN) METHOD OF INDICATING A CHANGED ANGULAR POSITION BETWEEN WEAR RINGS IN WHEEL PAIRS OF RAIL VEHICLES
(FR) PROCEDE D"INDICATION DU CHANGEMENT DE LA POSITION ANGULAIRE ENTRE LES ANNEAUX DE FRICTION DANS LES PAIRES DE ROUES DES VEHICULES SUR RAIL
Abstract: front page image
(EN)A changed angular position between the two steel wear rings of a rotationally fixedly connected pair of wheels of a rail vehicle are indicated by applying a magnetic pattern to the wear ring (3) and sensing the magnetic pattern by means of sensors (6, 7) connected to a comparator (9) interpreting the magnetic picture by comparing the magnetic patterns of both wear rings (3), enabling in this way to determine the mutual angular position of the wear rings (3). The magnetic pattern is constituted by one or more permanent magnetic fields of the wear rings, preferably arranged so that every second field is of a direction opposite to the preceding field.
(FR)Un changement de la position angulaire entre les deux anneaux de friction d"une paire de roues liees de maniere fixe et rotative d"un vehicule sur rail est indique en appliquant une configuration magnetique a l"anneau de friction (3) et en detectant la configuration magnetique au moyen de detecteurs (6, 7) connectes a un comparateur (9) qui interprete l"image magnetique en comparant les configurations magnetiques des deux anneaux de friction (3), ce qui permet de determiner la position angulaire respective des anneaux de friction (3). La configuration magnetique est constituee par un ou plusieurs champs magnetiques permanents sur l"anneau de friction, disposes de preference de maniere telle que chaque champ ait une direction opposee a celle du champ precedent.
