Abstract

Ce dispositif de mise en synchronisme d'un pignon Il de boîte de vitesse avec l'arbre 8 comporte, comme il est habituel, un manchon baladeur 16 qui vient craboter avec une couronne de synchronisation 25 puis avec les dents de crabotage 21 du pignon 11. La denture interne 29 du manchon baladeur 16 de l'invention comporte alternativement des zones à denture courte, qui engrènent avec les dents de crabotage de la couronne de synchronisation et des dents longues qui engrènent directement avec les dents de crabotage 21 du pignon 11. Il en résulte un raccourcissement du déplacement nécessaire du manchon baladeur.
