Abstract
L'invention concerne une boîte de transmission à vitesse variable. Elle comprend un arbre d'entraînement d'entrée, un dispositif à manivelle à excentricité variable, un dispositif pour accoupler la manivelle avec l'arbre, un dispositif pour modifier l'excentricité de la manivelle, un élément de liaison monté à rotation sur le dispositif à manivelle, plusieurs accouplements comportant des bras de manivelle, plusieurs bielles qui relient les bras de manivelles des accouplements à l'élément de liaison afin de faire osciller les bras de manivelle lorsque l'élément de liaison est déplacé par le dispositif à manivelle à excentricité variable, et des moyens reliés aux accouplements et entraînés en rotation par ceux-ci. Cette boîte de transmission est destinée en particulier aux automobiles.
