摘要： The present invention relates to a dual-clutch gearbox which can switch output shafts of two gearboxes, including a box body in which a rotating shaft configured to receive torque from a drive motor is provided. Two gears, which are both in slip fit on the rotating shaft and respectively in linkage with the output shaft of one gearbox, are coaxially sleeved on the rotating shaft. A motion bar is fitted to and provided on the rotating shaft, a linkage piece in coaxial linkage with the rotating shaft is fixed at one end of the motion bar, and a driver is in linkage with the other end of the motion bar, so that the motion bar can move in its own axial direction under the action of the driver and allow the linkage of the linkage piece with one of the two gears. According to the present invention, the output shafts of the two gearboxes can be used selectively to switch two functions, and the advantages are that fewer gearboxes are used, the drive motor and the gearboxes take up less space, and the structure is more compact.
