Planetary gear is a constant mesh transmission, its gear change is not brought into engagement or disengagement by moving the gears, its gear ratio change can be conveniently realized by disengaging or engaging the shift elements, and it is particularly advantageous to realize power shifting or automatic shifting. The two gear shifting executing elements brake the gear ring of the planetary gear mechanism according to a certain rule, and the planetary gear mechanism can obtain different transmission ratios without transversely moving gears, so that the gear shifting of each gear is realized, the axial length of the transmission can be shortened, and the requirement of the whole vehicle on the multi-gear transmission can be met. The three-planetary-row hybrid power two-gear automatic transmission assembly is of a coaxial transmission structure, and compared with a traditional multi-shaft transmission, the size of the transmission can be obviously reduced. Because the planetary gear transmission adopts multi-point meshing transmission, small gear modules can be used for transmitting the same moment, so that the size is small and the weight is light. In addition, the symmetry of multi-point engagement not only balances radial force, but also ensures stable movement, strong shock resistance and vibration energy and long service life.
