Power-driven system and vehicle having the same

A power-driven system, comprising:

• a differential, wherein the differential comprises:
• a first planet carrier, a first planet gear, and a first ring gear, wherein the first planet gear is disposed on the first planet carrier and meshes with the first ring gear;
• and
• a second planet carrier, a second planet gear, and a second ring gear, wherein the second planet gear is disposed on the second planet carrier, and meshes with the second ring gear and the first planet gear,
• wherein each of the first ring gear and the second ring gear comprises:
• a main plate part and an annular side wall part disposed on an outer periphery of the main plate part, wherein multiple teeth are disposed on an inner surface of the annular side wall part, a cavity is limited between the main plate part and the annular side wall part, a first cavity of the first ring gear and a second cavity of the second ring gear face towards each other to form a mounting space, and the first planet carrier, the first planet gear, the second planet carrier, and the second planet gear are accommodated inside the mounting space, and
• wherein the first ring gear and the second ring gear form two power output ends of the differential, and the first planet carrier and the second planet carrier form a power input end of the differential;
• a power output shaft, wherein the power output shaft is configured to link to the power input end of the differential;
• multiple input shafts, wherein one input shaft of the multiple input shafts is configured to selectively link to the power output shaft, and another one input shaft of the multiple input shafts is configured to link to the power output shaft;
• and
• a first motor generator, wherein the first motor generator is configured to link to the one input shaft of the multiple input shafts.
