Abstract

La présente invention concerne un arbre central d'un seul tenant pour une bicyclette avec arbres jumeaux couplés comprenant un arbre central d'entraînement (1) et un logement d'arbre central (3), caractérisé en ce que : un axe de manchon (2) est monté entre l'arbre central d'entraînement (1) et le logement d'arbre central (3); l'arbre central d'entraînement (1) est inséré dans un orifice de l'axe de manchon (2) via un palier d'arbre central d'entraînement (7); l'axe de manchon (2) est inséré dans un orifice du logement d'arbre central (3) via un palier d'axe de manchon (9). Alors que la détente de l'arbre central d'entraînement (1) est appliquée à la force sur l'axe de manchon (2), l'axe de manchon modifie la direction linéaire de la détente et pivote légèrement dans la direction radiale à l'intérieur du cercle interne du logement d'arbre central (3). L'arbre central comprend trois fonctions en une : il possède une précision élevée, est simple d'utilisation et offre de la constance lors du calibrage des signaux de sortie lors de la production.
