The invention relates to the technical field of motor transmission, in particular to a motor transmission buffer mechanism for starting and speed change of a pure electric vehicle, which comprises a planet wheel power distribution system, a speed reduction transmission mechanism, a hydraulic transmission conversion mechanism, a hydraulic pipeline and an adjustable hydraulic energy storage system, the planet wheel power distribution system comprises a center driving sun wheel, a planet carrier output wheel train and an annular driving adjusting gear, the planet carrier output wheel train is connected with an output sleeve, the output sleeve is connected with a wheel driving mechanism of the vehicle, and the center driving sun wheel is connected with a driving input shaft. And the output sleeve is sleeved on the outer side of the driving input shaft to form rotary sleeve connection. The driving force of the center driving sun wheel is decomposed and converted into the wheel driving force and the variable speed
