Abstract

"TRANSMISSãO HIDROSTáTICA CONTINUAMENTE VARIáVEL". A presente invenção refere-se a uma transmissão hidrostática continuamente variável CVT, uma bomba hidráulica P e um motor hidráulico M, a fim de eliminar a elevação na temperatura do óleo de trabalho em um circuito fechado hidráulico, são conectados através de um circuito fechado hidráulico, a capacidade do motor hidráulico sendo variada para variar a velocidade continuamente. A transmissão apresenta um carretel de válvula (70) em um orifício de carretel (6d) formado em um eixo de saída de transmissão (6) que giratoriamente prende a bomba hidráulica e o motor hidráulico, o eixo de saída de transmissão (6) incorporando os percursos de óleo de ramificação externa (6b, 6c), que são conectados com uma passagem externa (57) e abertos para o orifício de carretel, e um percurso de óleo de ramificação interna (6a), que é conectado com uma passagem interna (56) e aberto para o orifício de carretel. Uma ranhura direita (72) na periferia do carretel de válvula (70) permite que o carretel de válvula se mova entre uma posição de soltura de embreagem, na qual os percursos de óleo de ramificação externa (6b, 6c) e o percurso de óleo de ramificação interna (6a) são conectados, e uma posição de engate de embreagem, na qual uma estria central (73) do carretel de válvula cobre pelo menos um orifício de embreagem de alta pressão, a ranhura direita (72) sendo conectada ao lado de fora através de um percurso de óleo de descarga com um orifício (70d).
