Abstract
(EN)
Provided are a transmission device of a dual clutch transmission, a dual clutch transmission, and a vehicle mounted therewith which are capable of suppressing wear by reducing the load on the clutch in the starting gear, prolonging the clutch replacement period. This dual clutch transmission comprises a first input shaft (11) which couples to a first clutch (C1), and a second input shaft (12) which couples to a second clutch (C2). Odd-numbered gears (G1, G3, G5) and even-numbered gears (G2, G4, G6) are alternately arranged between the first and second input shafts (11, 12) and the output shaft (3). When the vehicle is started, the starting gear (DG2) engages with the second input shaft (12) and the auxiliary gear (SG1), having a gear ratio at least one gear lower than the starting gear (DG2), simultaneously engages with the first input shaft (11), and the first clutch (C1) partially couples (at half clutch) with the first input shaft (11) and the second clutch (C2) simultaneously partially couples (at half clutch) with the second input shaft (12).

L'invention porte sur un dispositif de transmission d'une transmission à double embrayage, sur une transmission à double embrayage et sur un véhicule équipé de ce dispositif et de cette transmission, qui sont aptes à supprimer l'usure en réduisant la charge appliquée à l'embrayage dans le pignon de démarrage, en prolongeant la période de remplacement de l'embrayage. Cette transmission à double embrayage comprend un premier arbre d'entrée (11) qui s'accouple à un premier embrayage (C1), et un second arbre d'entrée (12) qui s'accouple à un second embrayage (C2). Des pignons impairs (G1, G3, G5) et des pignons pairs (G2, G4, G6) sont arrangés en alternance entre les premier et second arbres d'entrée (11, 12) et l'arbre de sortie (3). Lors du démarrage du véhicule, le pignon de démarrage (DG2) engrène avec le second arbre d'entrée (12) et le pignon auxiliaire (SG1), qui a un rapport d'engrenage inférieur d'au moins un au pignon de démarrage (DG2), et engrène simultanément avec le premier arbre d'entrée (11), et le premier embrayage (C1) s'accouple partiellement (à demi-embrayage) avec le premier arbre d'entrée (11), et le second embrayage (C2) s'accouple simultanément partiellement (à demi-embrayage) avec le second arbre d'entrée (12).
