At present, two or more planetary gear trains are adopted to be combined in the market, and although the structure combination of the hybrid power system is more free by adopting the plurality of planetary gear trains, the configuration of the hybrid power system is complex and diversified, and the complexity and the diversity of influencing factors of the power flow direction in the system and the efficiency of the system are increased. For example, in the existing new energy city public transport bus, the applied planet row hybrid power assembly system is mainly a coaxial arrangement scheme of double motors and double planet rows, and the following problems mainly exist:
1. the highest rotating speeds of the two driving motors are low, the peak torque is large, and the motor cost is high;
2. the coaxial arrangement scheme causes the power assembly to have larger axial length, high requirement on arrangement space and poor adaptability to vehicle types;
3. the system adopts a split type sealing scheme, and a plurality of sealing rings exist, so that the sealing difficulty is high, oil leakage is easy, and the maintenance difficulty is high;
4. the system can only be applied to urban buses alone, cannot be adapted to long-distance buses simultaneously, and can realize direct driving of vehicles by the engine, but the application probability of the direct driving of the vehicle by the engine is very low, and the vehicle type adaptability is poor.
5. Due to the limitation of gears, the system cannot be applied to vehicle types with large power and torque requirements, and the vehicle type adaptability is poor.
