Abstract

Cette boîte comporte un arbre d'entrée 1, un arbre récepteur 5 et un arbre intermédiaire 3 portant un pignon 4 qui intervient pour l'établissement de la marche arrière, non synchronisée. Selon l'invention, il est prévu un levier 16 oscillant, qui est amené en contact avec l'arbre d'entrée 1, préalablement à l'engagement du rapport de marche arrière, pour réaliser le freinage de cet arbre et éviter les craquements de dentures. L'actionnement du levier est réalisé à partir du mécanisme 9, 10 de sélection et d'engagement, par l'intermédiaire d'une tringle coulissante 14.
