Abstract

DISPOSITIF DE SECURITE POUR UN MECANISME DE TRANSMISSION A PLUSIEURS RAPPORTS. CE MECANISME COMPREND DEUX GOUPILLES DE BLOCAGE DISPOSEES ENTRE UNE PREMIERE ET UNE SECONDE TIGES D'UN MECANISME DE CHANGEMENT DE VITESSE ET DE DIRECTION, CES GOUPILLES AYANT UNE LONGUEUR SUPERIEURE A LA DISTANCE SEPARANT LESDITES TIGES. CHAQUE TIGE EST ENTOUREE DE PLUSIEURS GORGES DESTINEES A RECEVOIR LES GOUPILLES DE BLOCAGE. L'UNE DES TIGES PEUT SE DEPLACER DANS UNE PREMIERE OU DANS UN SECONDE DIRECTION EN REPOUSSANT, AU MOINS UNE DES GOUPILLES DE BLOCAGE DANS L'UNE DES GORGES DE LA SECONDE TIGE, AFIN D'EMPECHER UN MOUVEMENT ALTERNATIF INDESIRABLE DE CETTE DERNIERE. LA SECONDE TIGE NE PEUT SE DEPLACER QUE QUAND LA PREMIERE EST DANS SA POSITION NEUTRE. L'INVENTION S'APPLIQUE AUX SYSTEMES DE COMMANDE DE CHANGEMENT DE VITESSE A RAPPORTS MULTIPLES QUI SONT COMMANDES PAR UN LEVIER DE CHANGEMENT DE VITESSE ET PAR UN LEVIER DE DIRECTION, NOTAMMENT, POUR VEHICULES DE TRAVAUX PUBLICS ET EST DESTINEE A EMPECHER UN ACTIONNEMENT INOPINE DU CHANGEMENT DE DIRECTION QUAND UN RAPPORT DE TRANSMISSION ELEVE A ETE ETABLI.
