Abstract

"RODA DENTADA PARA BICICLETA COM UM DENTE DE MUDANçA DE ENGRENAGENS QUE SE PROJETAM LATERALMENTE". A presente invenção refere-se a roda dentada que compreende um corpo de roda dentada e uma pluralidade de dentes de roda dentada que se estendem radialmente para fora de uma porção de base do corpo de roda dentada. O corpo de roda dentada tem uma primeira superfície lateral e uma segunda superfície lateral, em que uma superfície lateral de porção de base da porção de base define um plano de porção de base na primeira superfície lateral do corpo de roda dentada. Uma reentrância de auxílio de deslocamento é formada na porção de base abaixo de um primeiro dente de roda dentada na primeira superfície lateral do corpo de roda dentada e um segundo dente de roda dentada tem uma porção projetante que se estende lateralmente para fora do plano de porção de base na primeira superfície lateral do corpo de roda dentada.
