Abstract

L'invention décrite est un perfectionnement des systèmes de transmission actuellement utilisés pour les véhicules à pédales, tel que les bicyclettes, les tricycles etc. Il optimise la performance mécanique de pédalage en stabilisant la variation du couple exercée sur l'axe du pédalier. Cette nouvelle version des systèmes de pédalage utilise des plateaux de forme elliptique. Ces plateaux dont les dents sont réparties sur une ellipse aux dimensions bien précises sont dénommés plateaux elliptiques.Le système de transmission selon l'invention comporte un ou plusieurs plateaux de forme elliptique, installés sur l'axe du pédalier et/ ou sur l'axe de la roue libre. Il est prévu un dispositif tendeur pour assurer le contact entre la chaîne de transmission et le plateau elliptique.
