AI Technical Summary
The existing drive system uses a parallel shaft arrangement for multiple motors, which results in excessive space occupation in the front and rear directions of the vehicle, affecting the arrangement of collision energy absorption structures and potentially impacting safety.
The first and second motor assemblies are arranged coaxially, with the engine and motor assemblies positioned opposite each other to reduce space occupation. Furthermore, the kinetic energy transmission is optimized through a rotating shaft and a reduction mechanism to reduce space occupation in the radial and axial directions.
It effectively reduces the space occupied by the drive assembly in the front and rear directions of the vehicle, ensures collision safety, improves space utilization and oil-electric conversion efficiency, and optimizes the rationality of vehicle layout.
