Abrégé
(EN)
The invention discloses a transmission, a power drive system and a vehicle. The transmission comprises a first planetary gear mechanism, a second planetary gear mechanism, an input shaft, an intermediate shaft, a first synchronizer and a second synchronizer. A second planetary carrier of the second planetary gear mechanism is connected with the output end of the transmission. The input shaft is connected with a first sun gear. A first toothed ring is connected with the intermediate shaft. The intermediate shaft is connected with the second sun gear. The first synchronizer enables the first planetary carrier to be fixed to a shell of the transmission or to be connected with the first sun gear. The second synchronizer enables a second toothed ring to be fixed to the shell of the transmissionor to be connected with the first toothed ring. According to the transmission, by arranging the double-planetary-line double-synchronizer structure, rapid, smooth and reliable gear shifting can be achieved; and the transmission is simple in structure and convenient to maintain.
