ELECTRIC FORCE TRANSMISSION DEVICE

WIPO Patent Application WO/2006/013840

A2

An electric force transmission device, comprising a differential device formed of three or more rotating members and having two degrees of freedom whereby when the rotating state of two of these rotating members, the rotating state of the other rotating members is determined. An output to a drive system is transmitted to the rotating member positioned on an inside on an alignment chart among the rotating members, and two motor/generator units are coupled to the rotating members positioned on both sides of the rotating member related to the output on the alignment chart so that the drive system can be driven by only a power from the motor/generator units. The electric force transmission device is characterized in that when the driving is started from an output rotational speed of zero, before the driving is started, both motor/generator units are rotated oppositely to each other while keeping the state of the output rotational speed of zero.
