New energy automobile power flexible transmission system

The utility model relates to a new energy automobile power flexible transmission system, including driving motor and derailleur, its characteristics lie in, driving motor pass through torsional damper with the derailleur drive is connected, and torsional damper's initiative dish links firmly with the driving motor output shaft through inertial flywheel mutually promptly, and torsional damper's hub plate links firmly with the input shaft of derailleur mutually. This system can avoid low frequency resonance phenomenon and reduce transmission system's torsional oscillation and noise, reduces the gear shift of new energy automobile EMT in shifting impact and assaults, reduces disturbance moment of torsion excitation reverse action reverse torsional impact to driving motor when the drive line. Thereby can improve vehicle starting, accelerate stationarity and gear shift ride comfort and riding comfort, reduce and strike the harm that causes power transmission unit because of the shake, have of great significance to
