A hydraulic control system of the present invention is provided for improving a responsiveness to a speed change by compleating the speed chang with a torque pressure control hydraulic pressure after initiating the speed change with the drive hydraulic pressure. The hydraulic control system includes an oil pump for generating hydraulic pressure, a pressure regulating valve for regulating the hydraulic pressure to be proper pressure for reverse and drive, five friction elements which receive the hydraulic pressure for drive in accordance with operation of a manual valve, two friction elements which receive the hydraulic pressure for reverse in accordance with operation of the manual valve, first and second shift control parts having at least two shift valves, respectively, to supply the hydraulic pressure to the friction elements, and a torque control hydraulic pressure regulating part for supplying a torque control hydraulic pressure to the first and second shift control parts.
Cette invention concerne un système de commande hydraulique conçu pour mieux réaliser un changement de vitesse en achevant le changement de vitesse via une pression hydraulique asservie au couple après avoir amorcé le changement de vitesse via la pression hydraulique d'entraînement. Il comprend une pompe hydraulique développant une pression hydraulique, un régulateur de pression hydraulique adaptant la pression à la marche arrière et à la marche avant, cinq éléments de friction conçus pour recevoir la pression hydraulique d'entraînement réglée par un robinet manuel, deux éléments de friction conçus pour recevoir la pression hydraulique de marche arrière commandée par le robinet manuel, un premier et un second sélecteurs de vitesse ayant chacun au moins deux soupapes de passage des vitesses servant à alimenter les éléments de friction en pression hydraulique et un régulateur de pression hydraulique asservi au couple destiné à alimenter lesdits premier et second sélecteurs de vitesse en pression asservi au couple.
