The invention discloses a dual-clutch variable-speed electric automobile motor-flywheel hybrid power transmission device, and belongs to the field of automobile transmission. The transmission device comprises a motor, a double-clutch structure and a power output structure and further comprises a planet wheel structure, a sun wheel shaft of the planet wheel structure is in transmission connection with a low-speed-gear clutch of the double-clutch structure, a gear ring is in transmission connection with a high-speed-gear clutch of the double-clutch structure, and a planet carrier is in transmission connection with a main speed reducer of the power output structure. The device also includes a stepless speed change mechanism. A gear ring of the planet wheel mechanism is in transmission connection with the stepless speed change mechanism through a first transmission mechanism, and a sun wheel shaft is in transmission connection with the stepless speed change mechanism through a second transmission mechanism. The device also includes a flywheel mechanism in transmission connection with the stepless speed change mechanism through a third transmission mechanism; the device further comprises a gear ring brake and a sun gear brake. According to the device, the impact degree on parts of a transmission system in the gear shifting process is small, braking energy can be effectively recycled, and energy stored by the flywheel is fully utilized.
