Abstract

Les vélos sont des véhicules qui fonctionnent traditionnellement avec la force musculaire. Le développement des accumulateurs de puissance a permis de réaliser des moteurs auxiliaires en tant que moteurs électriques tout en respectant l'environnement. Ces vélos électriques font maintenant partie intégrante de la rue, par exemple Pedelec. Le but de la présente invention est de proposer un ensemble de générateurs véhicule équipé d'un moteur électrique et de pédales ainsi qu'un véhicule correspondant qui peut être utilisé de manière particulièrement efficace. Pour cela, il est proposé un ensemble de générateurs 2, destiné à un véhicule 1, qui est équipé d'au moins une unité de pédalage 3a pour introduire une force de pédalage, l'ensemble de pédalage 3a comprenant une pédale 4a destinée à être actionnée par les muscles, d'une unité génératrice 5 destinée à convertir la force de pédalage en énergie électrique, et d'une transmission 6. L'au moins une unité de pédalage 3a est et/ou peut être reliée à l'unité génératrice 5 par la transmission 6 cinématiquement et/ou par une technique d'engrenages, la pédale 4a étant guidée linéairement.
