Abstract

"TRANSMISSãO DO TIPO DE TRAçãO DE ROLAMENTO DE CALHA TOROIDAL". Um variador do tipo de tração de rolamento de calha toroidal, tem um disco de entrada rotativamente montado (18, 20), um disco de saída (22) rotativamente montado de modo coaxial com o disco de entrada (18, 20), uma pluralidade de rolos (30, 32) transmitindo rotação entre o disco de entrada e o disco de saída e uma pluralidade de pistões de ação dupla (346, 38) cada um atuando em um respectivo dos rolos. O variador também possui uma pluralidade de alavancas (44, 60), cada uma conectada a um respectivo dos rolos (30, 32) e seu atuador associado (36, 38). Conectando os atuadores aos rolos por meio de alavancas, pode ser obtida uma disposição muito mais compacta.
