Abstract: front page image
(EN) Provided is a hydraulic oil control device (80) having a shifting control unit (83) configured to, in a case where, when upshifting which involves switching of a clutch (21 or 22) and changing of a gear is performed, a number of revolutions of an input shaft (31 or 32) connected to a to-be-engaged clutch is higher than a number of revolutions of the engine 10, or a case where, when downshifting which involves the switching of the clutch and the changing of the gear is performed, the number of revolutions of the input shaft is lower than the number of revolutions of the engine 10, supply the to-be-engaged clutch with a hydraulic oil having a pressure equal to or higher than a predetermined standby pressure during at least a part of a period of time from when gear disconnecting is completed until the number of revolutions of the input shaft becomes equal to the number of revolutions of the engine 10, and then to supply the to-be-engaged clutch with the hydraulic oil having the standby pressure until gear connecting is completed, and configured to cause the to-be-engaged clutch to be engaged by supplying the to-be-engaged clutch with the hydraulic oil having a pressure higher than the standby pressure after the gear connecting is completed.
(FR) L'invention concerne un appareil de commande d'huile hydraulique (80), lequel appareil a une unité de commande de boîte de vitesses (83) qui fournit, quand la vitesse de rotation d'un arbre d'entrée (31 ou 32) relié à un embrayage côté fixation est supérieure à la vitesse de rotation d'un moteur (10) pendant un passage à la vitesse supérieure accompagné par la commutation d'un embrayage (21 ou 22) et un changement de vitesses, ou quand la vitesse de rotation de l'arbre d'entrée est inférieure à la vitesse de rotation du moteur (10) pendant un passage à la vitesse inférieure accompagnée par une commutation d'embrayage et un changement de vitesse, de l'huile hydraulique à une pression supérieure ou égale à une pression d'attente prescrite à l'embrayage côté fixation pendant au moins une partie d'une période de temps entre le moment où un débrayage est achevé et le moment où la vitesse de rotation du moteur (10) est égale à la vitesse de l'arbre d'entrée, puis qui fournit de l'huile hydraulique à la pression d'attente jusqu'à l'achèvement de l'embrayage, et qui règle l'embrayage côté fixation dans un état fixé par le fait de fournir une pression supérieure à la pression d'attente après l'achèvement de l'embrayage.
