Abstract

"EMBREAGEM UNIDIRECIONAL". A invenção refere-se a uma embreagem unidirecional compreende um cubo giratório interno (2), cubo giratório externo (3) acionado em uma direção específica e provido com uma pluralidade de cavidades (4) em sua circunferência interna que faceia a circunferência externa do cubo giratório interno (2) e furos de fixação roscados (3a) a serem usados para a fixação de um membro acionado ao cubo giratório externo (3), cilindros (5) respectivamente colocados na pluralidade de cavidades (4), e membros elásticos (6) que pressionam os cilindros (5) em uma direção específica. Um intervalo angular central entre a cavidade intermediária (4) em quaisquer três cavidades sucessivas (4) dentre a pluralidade de cavidades (4) e a cavidade adjacente (4) sobre o lado dianteiro da cavidade intermediário (4), e um intervalo angular central entre a cavidade intermediária (4) e a cavidade adjacente (4) sobre o lado traseiro da cavidade intermediário são diferentes um do outro. Sendo assim, a distância (d) entre a superfície de extremidade frontal (4b) da cavidade (4) e o furo de fixação roscado (3a) sobre o lado dianteiro da cavidade (4) é suficiente, e a redução da rigidez do cubo giratório externo (3) pode ser evitada sem aumentar o diâmetro do cubo giratório externo (3). As molas (6) podem ser molas espirais chatas de uma seção transversal tendo lados mais longos paralelos t ao comprimento do cilindro (5), e seguradores de grupo de molas em forma de U (7) tendo, cada qual, um par de paredes laterais que podem ser colocadas na extremidade sobre o lado dos cilindros (5) das molas (6), respectivamente.
