Drive system for use with mechanically coupled flywheel energy storage for recuperation of mechanical energy in electrically powered vehicles, has electric motor for providing driving torque to drive shaft

摘要

The drive system has an electric motor (10) for providing driving torque to a drive shaft (20) and a variator (30) for providing a continuously variable transmission ratio between the drive shaft and the flywheel energy storage (40). A control unit (400) is provided for controlling the electric motor and for adjusting the transmission ratio of the variator.
