Abstract: front page image
(EN)Provided is a belt type continuously variable transmission (1-1; 1-2; 1-3; 1-4) that includes a primary pulley (50); a secondary pulley (60); a belt (100) where the primary pulley (50) and the secondary pulley (60) are bound; a positioning hydraulic chamber (55) which presses a primary movable sheave (53) to a primary fixed sheave (52); a supply-side valve (71) and a discharge-side control valve (72) which controls the permission or the prohibition of the discharge of the working oil from the positioning hydraulic chamber (55) to the outside. The discharge-side control valve (72) prohibits the discharge of the working oil from the positioning hydraulic chamber (55) to the outside when a position of the primary movable sheave (53) is kept constant in the axial direction with respect to the primary fixed sheave (52).
(FR)L’invention concerne une transmission continuellement variable à courroie (1-1; 1-2; 1-3; 1-4) englobant une poulie primaire (50) ; une poulie secondaire (60) ; une courroie (100) avec laquelle la poulie primaire (50) et la poulie secondaire (60) sont liées ; une chambre hydraulique de positionnement (55) comprimant une poulie mobile primaire (53) contre une poulie fixe primaire (52) ; une valve côté alimentation (71) et une valve de commande côté refoulement (72) contrôlant la permission ou l’interdiction de refoulement d’huile de travail depuis la chambre hydraulique de positionnement (55) vers l’extérieur. La valve de commande côté refoulement (72) empêche le refoulement de l’huile de travail depuis la chambre hydraulique de positionnement (55) vers l’extérieur lorsqu’une position de la poulie mobile primaire (53) est maintenue constante dans la direction axiale par rapport à la poulie fixe primaire (52).
