Abstract

DISPOSITIVO DE OPERAçãO DE MUDANçA DE MARCHA DE BICICLETA. A presente invenção refere-se a um mecanismo de acionamento 39 de uma porção de operação de mudança de marcha traseira 16 que inclui uma pluralidade de porções de operação 71a a 71c que são colocadas em linha de modo a serem montadas de forma móvel em uma porção de montagem 30 em posições espaçadas de um eixo de suporte 31, se encaixam em uma lingüeta de posicionamento 56 por um movimento de uma alavanca de liberação 35 em uma primeira direção para se mover a lingüeta de posicionamento de uma primeira posição de encaixe para uma primeira posição de liberação, e libera o encaixe com a lingüeta de posicionamento 56 por um movimento de lingüeta de impedir rotação 57 em uma faixa predeterminada, de modo que a lingüeta de posicionamento seja móvel para a primeira posição de encaixe.
