Abstract

"CIRCUITO DE CONTROLE HIDRáULICO PARA TRANSMISSãO CONTINUAMENTE VARIáVEL" A presente invenção apresenta um circuito de controle hidráulico para uma transmissão de razão continuamente variável. Um circuito de controle hidráulico para uma transmissão CVT inclui uma primeira válvula de controle de pressão hidráulica V~ 1~ para controlar a pressão do fluido hidráulico a ser fornecido aos pistões de controle de cilindro do variador e uma segunda válvula de controle de pressão hidráulica V~ 2~ para controlar a pressão do fluido hidráulico a ser fornecido a uma disposição de embreagem da transmissão. As válvulas V~ 1~, V~ 2~ são ligadas em série de fluxo e por um primeiro dispositivo de válvula direcionador de fluido V~ 3~ (S~ 1~, S~ 2~) para direcionar o fluxo de cada bomba P~ L~, P~ R~ até um primeiro ponto P a montante da válvula V~ 1~ou até um segundo ponto P a jusante da válvula V~ 1~, mas a montante da válvula V~ 2~. Pela adoção de tal disposição, é possível controlar as embreagens sem que seja afetada a posição dos cilindros e vice versa.
