2. the coaxial arrangement scheme causes that the axial length of the power assembly is larger, the requirement on the arrangement space is high, and the adaptability of the vehicle type is poor;
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 be only applied to urban buses and cannot be simultaneously adapted to the buses, and the engine can directly drive the vehicles, but the application probability of the engine to directly drive the vehicles is very low, so that the adaptability of the vehicle type is poor;
5. the system does not have a limp home function, and once the electric drive system fails, only the trailer can be used.
The invention aims to solve the five problems and provides a double-motor double-planet-row parallel arrangement hybrid power assembly scheme. The system adopts the following scheme:

3. the motor and mechanical assembly components are intensively water-cooled, so that the sealing element is reduced, the sealing reliability is improved, the service life of the sealing element is prolonged, and the bearing and the gear can be synchronously lubricated;
4. through designing the connection mode of the double planetary rows and the engine, the use probability of the engine for directly driving the whole vehicle to run is improved, the transmission efficiency of the power assembly system is higher, and the fuel consumption of the system is reduced;
5. the limp function switching device is adopted, so that the vehicle can be limped to home under the condition that the electric drive system is invalid, and the vehicle is prevented from being towed;
6. according to the transmission structure adopted by the system, the double planetary rows share the gear ring, so that the power of the engine can be decoupled, one part of the power is transmitted to the rear axle, the other part of the power is transmitted to the first motor to generate electricity, and the two planetary rows decouple the power of the engine, so that the engine can be fixed at an optimal oil consumption point to work without being influenced by the speed of the vehicle.
