Electric vehicle and three-clutch transmission device for same

The invention discloses a three-clutch transmission device for an electric vehicle. The three-clutch transmission device is characterized by comprising an input shaft (1), a K1 clutch (2), a K2 clutch (3), a K3 clutch (4), a first-gear gear (5), a second-gear gear (6), a third-gear gear (7), an output shaft (10), a conduction device (11) and a gear controller, wherein the K1 clutch (2), the K2 clutch (3) and the K3 clutch (4) are respectively connected with the first-gear gear (5), the second-gear gear (6) and the third-gear gear (7); the gear controller automatically controls the output shaft (1) to be switched into different shifts through different clutches; and the output shaft (10) is connected with a gear-shifting gear through the conduction device (11). The three-clutch transmission device for the electric vehicle can be used for the electric vehicle and has the advantages of power gear shifting, short gear shifting time, good gear shifting quality, simple structure, low cost and the like.
