A two-speed variable-speed bridge driving system with double clutches comprises a double clutch (DC), a planetary gear set (PG) and a differential (D), a motor shaft (Se) is connected with a rotor of a motor (E) and a driving part of the double clutch (DC), a first driven disc (C1) of the double clutch (DC) is connected with a first input shaft (S1), a second driven disc (C2) of the double clutch (DC) is connected with a second input shaft (S2), and the planetary gear set (PG) is connected with the differential (D). The first input shaft (S1) is used for transmitting torque to the first gear set, the second input shaft (S2) is used for transmitting torque to the second gear set, the first gear set and the second gear set are both used for transmitting torque to the output shaft (So), the output shaft (So) is connected with a sun gear of the planetary gear set (PG), and a planet carrier of the planetary gear set (PG) is connected with a shell of the differential (D). According to the two-gear variable-speed bridge driving system with the double clutches, all the components are simple and compact in structure, the system reliability is high, the NVH influence is small, and power interruption can be avoided in the gear shifting process.
