Abstract

L'invention concerne un système comprenant un rotor (1) monté en rotation par rapport à un organe fixe (2), ledit système comprenant une cloche (4) solidaire en rotation dudit rotor, ladite cloche présentant un logement (5) délimité par une paroi annulaire axiale (4a) qui est formée autour dudit rotor, ledit système comprenant un dispositif de détermination d'au moins une information relative à la rotation du rotor (1), ledit dispositif comprenant un codeur (6) apte à générer un signal représentatif de sa rotation et un capteur (7) solidaire de l'organe fixe (2) qui est apte à déterminer ladite information par lecture du signal généré par ledit codeur, la cloche (4) présentant une collerette cylindrique (4c) qui s'étend radialement depuis un bord externe de la paroi annulaire (4a) en formant avec l'organe fixe (2) un espace annulaire (8), le codeur (6) étant fixé à la collerette (4c) de sorte à être disposé dans l'espace annulaire (8) à distance de lecture par ledit capteur du signal généré.The invention relates to a system comprising a rotor (1) mounted in rotation with respect to a fixed member (2), said system comprising a bell (4) fixed in rotation to said rotor, said bell having a housing (5) delimited by a axial annular wall (4a) which is formed around said rotor, said system comprising a device for determining at least one item of information relating to the rotation of the rotor (1), said device comprising an encoder (6) capable of generating a representative signal of its rotation and a sensor (7) integral with the fixed member (2) which is able to determine said information by reading the signal generated by said encoder, the bell (4) having a cylindrical collar (4c) which extends radially from an outer edge of the annular wall (4a) forming with the fixed member (2) an annular space (8), the encoder (6) being fixed to the flange (4c) so as to be disposed in the annular space (8) at a distance reading by said sensor of the signal g excited.
