Abstract

"DENTE DE CATRACA DE BICICLETA COM UM RAIO AUXILIAR DE CáMBIO MAIOR QUE UM RAIO DE DENTE DE REFERêNCIA". A presente invenção refere-se a uma catraca de bicicleta compreende um corpo de catraca que possui uma primeira superfície lateral e uma segunda superfície lateral, uma pluralidade de dentes de catraca que se estendem radialmente para fora a partir de uma parte de raiz do corpo de catraca, e um recesso auxiliar de câmbio formado na parte de raiz abaixo de um primeiro dente de catraca na primeira superfície lateral do corpo de catraca. Uma superfície radialmente mais para fora de um segundo dente de catraca define um raio de dente de referência, e uma superfície radialmente mais para fora de um terceiro dente de catraca define um raio de dente auxiliar de câmbio. A superfície radialmente mais para fora do terceiro dente de catraca possui uma forma convexa, e o raio de dente auxiliar de câmbio é maior que o raio de dente de referência.
