Abstract

Le but de l'invention est de trouver une solution économique permettant d'améliorer la liaison entre un moyeu et un disque de frein, de manière à obtenir une meilleure ventilation lors d'un montage simple, une possibilité de codage mécanique devant être offerte. A cet effet, l'invention concerne un moyeu (10) pour véhicules ferroviaires comportant une collerette de fixation (12), pouvant être montée sur un essieu, et une bague de fixation (13) pourvue d'un certain nombre de trous de fixation (14) répartis sur la bague de fixation (13) et servant à fixer un disque de frein (11) pourvu de bras de fixation (17) qui correspondent aux trous de fixation (14) et sont chacun pourvus d'une ouverture axiale (19) permettant la liaison avec le moyeu (10). Selon l'invention, au moins un élément de prise (18) orienté axialement est placé entre les trous de fixation (14) sur la bague de fixation (13), lequel élément de prise peut s'engager dans un espace intermédiaire (20) formé entre deux bras de fixation (17a, 17b) du disque de frein (11), ledit espace intermédiaire (20) étant formé du fait de l'absence d'au moins un bras de fixation (17) par rapport à une structure de base (G) de bras de fixation (17) placés à distances angulaires égales les uns des autres, et/ou peut s'engager dans une rainure (26) située sur au moins un bras de fixation (17). L'invention concerne également un disque de frein réalisé de manière correspondante.
