  • the first double-gearshift clutch 56 To transmit the torque to the first output shaft 50, the first double-gearshift clutch 56 must be in a second shift position (a shift sleeve of the dual-gearshift clutch 56 is displaced in the direction of engine M). Thus, via the first output shaft 50 and the second pinion 51 of the output can be driven. For the realization of the reverse gear thus two gearshift clutches must be switched simultaneously, namely the bridge Doppelgangschaltkupplung 94 and the first Doppelgangschaltkupplung 56 on the first output shaft 50. Since the first fixed wheel 31 has a smaller diameter than the first transfer wheel 11, the torque transmission from the second Input shaft 30 connected to the first input shaft 10, starting from the first fixed gear 31 with a certain transfer ratio.

Abstract

L'invention concerne une boîte de vitesses à double embrayage comprenant deux arbres d'entrée (10, 30), au moins un premier arbre de sortie (50) et un arbre de pontage (90). L'arbre de pontage (90) permet de transmettre un couple d'un des arbres d'entrée (10, 30) à l'autre arbre d'entrée (30, 10). Un ensemble de pignons, qui est associé à une marche arrière, comprend un premier pignon fixe (31), un pignon intermédiaire (111) ainsi qu'un deuxième pignon fou de pontage (93). Le premier pignon fixe (31), lequel s'engrène avec le pignon intermédiaire (111), n'est pas en contact d'engrènement avec d'autres pignons.
