Abstract

La présente invention concerne des ensembles engrenages menants et menés comprenant des engrenages non circulaires ou un mécanisme de transmission à croix de Malte qui fonctionnent ensemble comme une transmission à variation continue qui ne dépend pas du frottement. Étant donné qu'un système à chaîne et à pignons fonctionne comme un système à cône et à courroie et que le système d'engrenages menants et menés, bien que distinct, change de rapport sans interruption, ils peuvent être considérés comme une transmission à variation pseudo continue. L'utilisation d'un système d'engrenages planétaires permet une sortie continue, de la marche avant à la marche arrière, comprenant le point mort. Avec la segmentation des engrenages circulaires et non circulaires, un passage en rapport supérieur et une rétrogradation s'obtiennent par un bref passage de l'ensemble motopropulseur, par l'intermédiaire d'un engrenage non circulaire, au rapport de transmission suivant pendant la transition. La présente invention offre également plusieurs façons d'obtenir une capacité ininterrompue de changement de rapport pour une transmission à plusieurs vitesses éliminant le besoin de synchroniseurs et permettant un raccordement direct à leur arbre respectif par l'intermédiaire d'un embrayage à crabot ou d'un dispositif analogue.
