A novel parallel hybrid driving system is presented
which consists of an engine
an anti-direction dual-rotor motor(ADDRM)
a planetary gear and etc.Without using the traditional transmission
the system achieves the continuously variable transmission functions in the hybrid mode by adjusting the moto rotating speed.Variety of operating modes as well as the output speed and the output torque in each modes of the system are analyzed.Taking a practical connecting mode as an example.Speed adjusting range of the continuously variable transmission in the parallel hybrid mode is components on the output speed ratio range are analyzed.
