Abstract

The bogie includes an axle (14) rotating on a fixed chassis. A measuring gauge (34) rotating with the axle comprises a metal disc (36), integral with the axle, with an open indicator (40). An indicator detector (50) has an inductive proximity detector (52). The disc is fixed on a commutator ring (26) of a return current unit (24) returning the current coming from a bogie motor to the axle.

Le disque ) (voir figure 2) est réalisé en deux parties ( et e réassemblées au moyen de 2 vis et de 2 pieds de centrage ( placés symétriquement, permettant ainsi un montage sur l'essieu sans aucune démontage préalable. Les encoches ou les trous sont réalisés en forme de trapèze () de façon à éviter l'accumulation de poussières ou de particules  The disc) (see figure 2) is made in two parts (and e reassembled by means of 2 screws and 2 centering feet (placed symmetrically, thus allowing mounting on the axle without any prior disassembly. The notches or holes are made in the shape of a trapezoid () so as to avoid the accumulation of dust or particles

Le montage du disque nécessitant une bonne précision de concentricité par rapport à l'axe de l'essieu, son centrage est réalisé à partir 2 pieds de centrage (1 par demi-disque) qui viennent se loger dans 2 trous préalablement usinés dans l'épaisseur de la bague collectrice du retour de courant. Cet usinage est effectué au moyen d'un outil spécial (voir figure 3) qui vient se fixer sur les 4 trous filetés qui existent la plupart du temps sur la surface latérale de la bague collectrice. Après une opération de centrage au comparateur, cet outil permet ainsi de percer les trous de centrage (3 dans lesquels viennent se loger les pions fixés sur les demi-disques, sans démontage préalable d'aucune pièce. Au cas o la ú bague collectrice ne posséderait pas déjà les trous filetés mentionnés ci-dessus, ce même outillage est fixé alors sur les 4 points de fixation du boîtier de retour de courant au moyen des 4 colonnettes () décrites ci-avant, permettant ainsi d'usiner les 4 trous de fixation manquants. Le lecteur (voir figure 4) est constitué d'un boîtier métallique () comprenant un certain nombre de sondes élémentaires de détection de type inductif (3 sont représentées sur la figure). Ces sondes fonctionnent à partir des courants de Foucault générés dans les parties métalliques placées devant l'extrémité active de chacune de ces mêmes sondes. Le boîtier du lecteur permet d'intégrer les divers raccordements électriques de chacune des sondes sur un bomrnier) et de leur dispositif de test associé ainsi que leur raccordement sur le  The mounting of the disc requires good concentricity accuracy with respect to the axis of the axle, its centering is carried out from 2 centering feet (1 per half-disc) which are housed in 2 holes previously machined in the thickness of the current return slip ring. This machining is carried out by means of a special tool (see Figure 3) which is fixed on the 4 threaded holes which exist most of the time on the lateral surface of the slip ring. After a centering operation with the comparator, this tool thus makes it possible to drill the centering holes (3 in which the pins fixed on the half-discs are housed, without prior disassembly of any part. In case the ú slip ring does not would not already have the threaded holes mentioned above, this same tool is then fixed on the 4 fixing points of the current return housing by means of the 4 columns () described above, thus making it possible to machine the 4 holes of The reader (see Figure 4) is made up of a metal case () comprising a certain number of elementary inductive type detection probes (3 are shown in the figure). These probes operate on the basis of the eddy currents generated. in the metal parts placed in front of the active end of each of these same probes. The reader housing allows integration of the various electrical connections of each of the probes s on a bomrnier) and their associated test device as well as their connection to the

Cette spire, une fois court-circuitée, influe directement sur le champ altemrnatif émis par la sonde, simulant ainsi la détection d'une partie métallique. La comparaison entre l'envoi d'une séquence logique particulière sur la commande de court-circuit de la spire et sa restitution sur le signal de sortie de la sonde permet d'effectuer un test de fonctionnement sûr. Par ailleurs, ce test n'étant réalisable que si la sonde est et reste en face d'une encoche ou d'un trou (absence  circuitable) of low resistance placed near its active end. This coil, once short-circuited, directly influences the alternating field emitted by the probe, thus simulating the detection of a metallic part. The comparison between the sending of a particular logical sequence on the short-circuit control of the coil and its restitution on the output signal of the probe makes it possible to carry out a safe functional test. Furthermore, this test is only possible if the probe is and remains in front of a notch or a hole (absence
