Abstract

Le coulisseau 20 commandant le synchroniseur 8 de quatrième vitesse porte une came 21 sur laquelle appuie un levier 22 sous l'action d'un ressort 24. Lors de l'engagement du pignon de marche arrière 13 le levier 22 provoque le déplacement du coulisseau 20 dans le sens de la flèche F. Lors de la commande d'une autre vitesse synchonisée un doigt 25 solidaire du levier 16a porté par le sélecteur 17 des rapports de transmission vient s'engager dans une encoche 26 du levier 22 et le soulève de la came 21 lors du pivotement du levier 16a. Les claquements entre les dents des pignons au point mort ainsi que tout craquement au passage de la marche arrière non synchronisée sont ainsi évités.
