Abstract

CAIXA DE MARCHAS COM DUPLA EMBREAGEM DE ENTRADA, E, PROCESSO DE FUNCIONAMENTO DA MESMA. Caixa de marchas com dupla embreagem de entrada, comportando duas árvores primárias concêntricas (1, 10), ligadas respectivamente à primeira embreagem (E1) e à segunda embreagem (E2), pinhões fixos (2, 3, 4, 11, 12) distribuídos entre as duas árvores primárias, duas árvores secundárias (20, 30) portando pinhões loucos (21, 22, 23, 24, 31, 32) engrenando com os pinhões fixos das árvores primárias e meios de acoplamento (M1, M2, M3, M4) dos pinhões loucos, caracterizada pelo fato de que a primeira relação de marcha para frente e a relação de marcha à ré são estabelecidas combinando a utilização do pinhão louco (24) de segunda relação de marcha para frente, e a união das duas árvores primárias (1, 10) através de dois pinhões loucos de relações intermediárias de carreiras adjacentes (22, 23) girando em torno da mesma árvore secundária (20) que o pinhão louco de segunda (24).
