Abstract
La présente invention concerne un système d'assistance électrique pour cycle (1) à assistance électrique, comprenant un dispositif de réduction (100) configuré pour transmettre un effort de rotation entre un organe moteur (201) entraîné en rotation par un moteur (200) électrique du cycle (1) et un arbre (11) du pédalier du cycle, l'axe de rotation dudit organe moteur étant perpendiculaire à l'axe de rotation de l'arbre (11) du pédalier, le dispositif de réduction (100) étant configuré pour fournir à l'arbre (11) du pédalier un couple supérieur à celui reçu dudit organe moteur (201), caractérisé en ce que le dispositif de réduction (100) comprend au moins un train épicycloïdal coaxial avec l'axe de rotation de l'arbre (11) du pédalier.The present invention relates to an electrical assistance system for an electrically assisted cycle (1), comprising a reduction device (100) configured to transmit a rotational force between a drive member (201) driven in rotation by a motor (200) electric of the cycle (1) and a shaft (11) of the pedal of the cycle, the axis of rotation of the said motor member being perpendicular to the axis of rotation of the shaft (11) of the pedal, the reduction device (100) being configured to provide the crankshaft (11) with a torque greater than that received from said drive member (201), characterized in that the reduction device (100) comprises at least one planetary gear train coaxial with the axis of rotation of the shaft (11) of the crankset.
