Abstract

Titre. Pédalier à plateau mobile La présente invention concerne un pédalier (10) pour cycle configuré pour être mécaniquement couplé par au moins une chaîne à au moins un pignon d’une pluralité de pignons et pour être supporté par au moins un cadre du cycle caractérisé en ce que le pédalier comprend : au moins un arbre de pédalier (15) configuré pour être guidé en rotation par moins des premier (13) et deuxième (14) paliers à roulements autour d’un axe de rotation principal (15a) ; au moins un chariot (16) solidaire en rotation de l'arbre de pédalier (15) autour de l’axe de rotation principale (15a) et monté libre en translation sur l'arbre de pédalier (15) le long de l’axe de rotation principale (15a) ; au moins un plateau (17) étant solidaire en rotation et en translation dudit chariot (16) et mécaniquement couplé avec un pignon au travers d’une chaîne. Figure pour l’abrégé : Fig. 6Title. The present invention relates to a crankset (10) for a cycle configured to be mechanically coupled by at least one chain to at least one sprocket of a plurality of sprockets and to be supported by at least one frame of the cycle characterized in that that the crankset comprises: at least one crankshaft (15) configured to be guided in rotation by less of the first (13) and second (14) rolling bearings about a main axis of rotation (15a); at least one carriage (16) integral in rotation with the crankshaft (15) around the main axis of rotation (15a) and mounted free in translation on the crankshaft (15) along the axis main rotation (15a); at least one plate (17) being integral in rotation and in translation with said carriage (16) and mechanically coupled with a pinion through a chain.
