Hybrid dual-power switching device of vehicle and gearbox composed of same

The invention relates to a hybrid dual-power switching device of a vehicle and a gearbox composed of the same. The device comprises a one-way driver I and a one-way driver II which are connected through the same shaft and are the same in structure. The output end of the vehicle hybrid dual-power switching device is used for being connected with a driving shaft of a gearbox, the input end of thevehicle hybrid dual-power switching device is used for being connected with an engine power output shaft and a motor power output shaft, and the vehicle hybrid dual-power switching device is used fortransmitting power generated by a vehicle engine or a motor to the gearbox. A hybrid power combination with a more reasonable structure is adopted, one gearbox achieves two-power speed changing, and an original vehicle clutch can be omitted during gear shifting of the gearbox. Therefore, the service life of the original vehicle clutch is prolonged, the inertia force of the vehicle in the running process is improved, and the
