Patent ID: RE44852

Claim:
A power distribution system for distributing revolving power in real time to drive a transportation vehicle, comprising: a power source for providing the revolving power; a dual-drive electromagnetic coupling device for regulating a distribution of power between a front-end load and a rear-end load of the vehicle, and for outputting power to drive the rear-end load, wherein the dual-drive electromagnetic coupling device comprises a revolving dual-end shaft with one end incorporated to a revolving magnetic field and the other end incorporated to a revolving rotor, wherein when the revolving dual-end shaft is driven by a revolutions-per-minute (RPM) difference of the front-end and rear-end loads the dual-drive electromagnetic coupling device functions as a generator to charge a rechargeable device and provides a passive regulation of the distribution of power, and when the revolving dual-end shaft is powered by the rechargeable device, the dual-drive electromagnetic coupling device functions as a motor so that the revolving dual-end shaft revolves clockwise or counter-clockwise to provide an active regulation of the distribution of power; and a transmission and control interface device for transmitting the revolving power to the front-end load and the dual-drive electromagnetic coupling device.
