Abstract

bicicletas de pedais eletricamente assistidos. trata-se de um sistema de acionamento para uma bicicleta na forma de um pedelec (10) que tem uma entrada (2) que recebe o acionamento de um pedal (40) da bicicleta e gira em torno do eixo geométrico (1). uma saída (100) gira em torno do eixo geométrico (1) para acionar uma roda (30) da bicicleta. uma máquina elétrica (5,6) fornece acionamento por motor para a saída (100). um trem de acionamento recebe o acionamento da máquina elétrica (5,6) e do pedal (40) e transmite o acionamento para a saída (100). o trem de acionamento compreende primeiro e segundo conjuntos de engrenagens epicicloidais (ep-1, ep-2), cada um dos quais compreende uma engrenagem solar (11,21), um suporte planetário (13,23), uma pluralidade de engrenagens planetárias (12,22) e uma engrenagem anular (14, 24). ambas as engrenagens anulares (14,24) são conectadas à saída (100) para girar com ela. ambas as engrenagens solares (11,21) são acionadas pela máquina elétrica (5,6). o primeiro conjunto de engrenagens epicicloidais (ep-1) transmite acionamento de seu sol (11) para seu anular (14) com seu suporte planetário (13) em uma posição fixa. o segundo conjunto de engrenagens epicicloidais (ep-2) transmite o acionamento de um pedal (40) para seu anular (24) por meio de seu suporte planetário (23). opcionalmente, a assistência elétrica pode ser fornecida quando o ciclista está pedalando e quando o ciclista não está pedalando.
