AI Technical Summary
Technical Problem
The existing longitudinal rear-drive dual-motor hybrid system requires a long layout space and is highly arranged. Under very low vehicle speeds, it is difficult for the engine to intervene in the drive wheel end, resulting in weak power.
Method used
The planetary row components are used to realize the transmission connection between the generator assembly and the power input shaft, shorten the layout length of the power system, and set the drive motor assembly and the power output shaft coaxially, simplify the structure and reduce manufacturing costs.
Benefits of technology
The compact layout of the power system is realized, the manufacturing cost is reduced, the space utilization is improved, and the power of the vehicle is improved under low-speed operating conditions.
