Abstract

L'invention concerne une appareil de sortie automatique permettant de convertir un entraînement bidirectionnel en un entraînement unidirectionnel et un vélo comprenant un tel appareil, dans lequel un groupe d'engrenage planétaire et un roulement unidirectionnel sont en prise l'un avec l'autre de manière que la puissance d'entraînement produite par l'entraînement dans une direction avant ou arrière sans dispositif ou action extérieur distinct quelconque, indépendamment de la direction d'entraînement de l'utilisateur, puisse être convertie en une sortie unidirectionnelle, un état de rotation planétaire et un état de freinage arrière. L'invention concerne également un vélo fabriqué au moyen d'un tel appareil et des moyens de retrait permettant d'éliminer de manière forcée l'état de freinage arrière verrouillé quand l'avancée arrière est nécessaire.
