Embodiment 1
[0054] An automatic transmission device for an electric vehicle, comprising a planetary gear mechanism 1, an output shaft 2, a first clutch 3, a second clutch 4 and a shift mechanism 5 arranged in a housing 6;
[0055] The output shaft 2 is driven by a motor 7 through a planetary gear mechanism 1;
[0056] The shift mechanism 5 controls the linkage switching between the first clutch 3 and the second clutch 4, and the linkage switching between the first clutch 3 and the second clutch 4 controls the locking and unlocking of the planetary gear mechanism 1 so as to realize two switch between gears;
[0057] The planetary gear mechanism 1 includes a first sun gear 11, a second sun gear 12, a planetary gear and a planet carrier 15. The first sun gear 11 is sheathed on the output shaft 2 and is rotationally connected with the output shaft 2. The first sun gear 11 is driven by the motor 7, and one end of the first sun gear 11 and the planetary gear meshes with each other, and the oth...
