The invention discloses a power drive
system and a vehicle. The power drive
system comprises a differential, a
power output shaft, a plurality of input shafts and a first
electric motor generator; the differential comprises a first
planet carrier, a second
planet carrier, a first
planet wheel, a second planet wheel, a first gear ring and a second gear ring, the first planet wheel is arranged on the first planet carrier, the second planet wheel is arranged on the second planet carrier, the first planet wheel is engaged with the first gear ring, the second planet wheel is engaged with the second gear ring, and the second planet wheel is further engaged with the first planet wheel; the
power output shaft is arranged to be linked with the power input end of the differential; one input shaft of the
multiple input shafts is arranged to be selectively linked with the
power output shaft, and the remaining input shafts are arranged to be linked with the power output shaft; the first
electric motor generator is arranged to be linked with one input shaft. According to the differential of the power drive
system, the planet differential principle is used for achieving the
differential function, and the structure is compact and simple.
