Abstract

"ALAVANCA DE MUDANçA DIANTEIRA DE BICICLETA". A presente invenção refere-se a uma alavanca de mudança dianteira de bicicleta possui um guia de corrente dotado de um elemento empurrador que pode se mover em relação ao guia de corrente para auxiliar o deslocamento de uma corrente de bicicleta de uma coroa dentada dianteira menor para uma coroa dentada maior adjacente. O guia de corrente faz porção de uma peça móvel acoplada com mobilidade a uma peça de base através de um conjunto articulado. O elemento empurrador possui uma superfície de contato a qual, de preferência, se move tanto lateralmente para fora como longitudinalmente enquanto o elemento empurrador se move de uma primeira posição para uma segunda posição. De preferência, o elemento empurrador é ativado por corrente e está disposto para se mover pelo menos lateralmente para fora mediante o contato com uma corrente que está se movendo entre peças de guia de corrente interna e externa da peça móvel. De preferência, o elemento empurrador é ou uma peça deslizante ou uma peça rotativa.
