Abstract

UM SISTEMA PARA PREVENçãO DE DESENGATE DE ENGRENAGEM EM UMA EMBREAGEM DE DENTE EM UMA TRANSMISSãO DE VEìCULO. A presente invenção se refere a um sistema para prevenção de desengate de engrenagem (de marcha) em uma embreagem de dente (de engrenagem) em uma transmissão de veículo, referida embreagem de dente compreendendo uma conexão de engate (117, 217, 351, 551) possuindo dentes de embreagem de conexão (118, 218, 718, 818, 918). Em concordância com a presente invenção, a função de tangente, para pelo menos um de ângulo afilado em reverso de tração (691d) e de ângulo afilado em reverso de frenagem (691b) é maior do que o valor médio de coeficiente de fricção de embreagem e de coeficiente de fricção de chave de junção (spline) multiplicado pela soma de unidade e a proporção de diâmetro de passo de engrenagem de dentes de embreagem e diâmetro de passo de engrenagem de dentes de chave de junção.
