Power system and vehicle

The invention discloses a power system and a vehicle, and belongs to the field of vehicle driving. The power system comprises a driving mechanism and a disengaging mechanism. The driving component is in transmission connection with one end of the transmission input shaft, and one end of the transmission output shaft is used for being connected with a to-be-driven wheel of a vehicle. The disengaging mechanism is connected with the transmission input shaft and the transmission output shaft. Thus, the end of the transmission input shaft and the end of the transmission output shaft are controlled to be in transmission connection through the disengaging mechanism, so that the driving component can drive the transmission input shaft, the disengaging mechanism and the transmission output shaft to rotate synchronously, that is, the driving force of the driving component can be output to the to-be-driven wheels in the vehicle, and then the wheels are driven to run. Besides, the disengagement mechanism also controls th
