Abstract
(EN) A transmission unit for a vehicle includes: a plurality of input shafts (11, 12), each of the input shafts (11, 12) provided with a shift driving gear (la-5a); a plurality of output shafts (21, 22), each of the output shafts (21, 22) being provided with a shift driven gear (lb-5b) configured to mesh with a corresponding shift driving gear (la-5a); a motor power shaft (3); first and second motor gears (31, 32) freely fitted over the motor power shaft (3); a motor synchronizer (33c) disposed on the motor power shaft (3) and between the first and second motor gears (31, 32); the first motor gear (31) is configured to rotate together with one of the input shafts (11, 12); the second motor gear (32) is configured to rotate together with one of the output shafts (21, 22). A power transmission system and a vehicle are also provided.
(FR) Une unité de transmission pour un véhicule selon l'invention inclut : une pluralité d'arbres d'entrée (11, 12), chacun des arbres d'entrée (11, 12) étant pourvu d'un engrenage d'entraînement de changement de vitesse (la-5a) ; une pluralité d'arbres de sortie (21, 22), chacun des arbres de sortie (21, 22) étant pourvu d'un engrenage entraîné de changement de vitesse (lb -5b) configuré pour s'engrener avec un engrenage d'entraînement de changement de vitesse correspondant (la-5a) ; un arbre de puissance moteur (3) ; des premier et second engrenages moteur (31, 32) ajustés librement sur l'arbre de puissance moteur (3) ; un dispositif de synchronisation moteur (33c) disposé sur l'arbre de puissance moteur (3) et entre les premier et second engrenages moteur (31, 32) ; le premier engrenage moteur (31) étant configuré de manière à tourner conjointement avec l'un des arbres d'entrée (11,12) ; le second engrenage moteur (32) étant configuré de manière à tourner conjointement avec l'un des arbres de sortie (21, 22). L'invention concerne également un système de transmission de puissance et un véhicule.
