Abstract
L'INVENTION SE RAPPORTE A UNE BOITE DE VITESSES POUR VEHICULE AUTOMOBILE, NOTAMMENT A UNE BOITE A ARBRE INTERMEDIAIRE ET SYNCHRONISEE, COMPRENANT PLUSIEURS RAPPORTS DE MARCHE AVANT ET UNE MARCHE ARRIERE, DANS LAQUELLE LES PIGNONS 11, 12 DE LA MARCHE ARRIERE SONT EUX AUSSI EN PRISE CONSTANTE ET DANS LAQUELLE, PENDANT LA TRANSMISSION DE LA FORCE, L'UN DES JEUX DE PIGNONS EST ENCLENCHE DANS LA CHAINE CINEMATIQUE DE LA BOITE PAR UN ACCOUPLEMENT A BALADEUR 13. POUR PERMETTRE L'ENCLENCHEMENT SILENCIEUX DE LA MARCHE ARRIERE, LE JEU DE PIGNONS 11, 12 DE LA MARCHE ARRIERE EST LUI-AUSSI MUNI D'UN SYNCHRONISEUR 17, 23. TOUTEFOIS, AFIN QUE LA MARCHE ARRIERE NE RISQUE PAS D'ETRE EGALEMENT ENCLENCHEE LORSQUE LE VEHICULE ROULE EN MARCHE AVANT , ON PREVOIT SUR LE TRAJET DE TRANSMISSION DE MOUVEMENT ENTRE LE LEVIER DE VITESSES MANOEUVRE PAR LE CONDUCTEUR ET L'ACCOUPLEMENT 13 DE LA MARCHE ARRIERE, UNE BUTEE 29, 32 QUI S'ENGAGE LORSQUE LA VITESSE DU VEHICULE EST SUPERIEURE A UNE VALEUR DONNEE ET, DANS CETTE POSITION D'ENGAGEMENT, BLOQUE LA MANOEUVRE D'ACCOUPLEMENT 13 DE LA MARCHE ARRIERE.
