Abstract:
A continuously variable transmission comprising:first and second planetary splitters; an input shaft in mechanical communication with each of said first and second planetary splitters; an output shaft in mechanical communication with each of said first and second planetary splitters; a first electric motor/generator for selectively driving or generating electrical energy from said first planetary splitters; and a second electric motor/generator for selectively driving or generating electrical energy from said second planetary splitter; wherein a low speed range operating mode is achieved through said second electric motor/generator generating electrical energy and feeding said electrical energy to said first electric motor/generator, a mid speed range operating mode is achieved through said first electric motor/generator generating electrical energy and feeding said electrical energy to said second electric motor/generator, and a high speed range is achieved through a lock-up clutch locking a component of said first planetary splitter and said second electric motor/generator generating electrical energy and feeding said electrical energy to said first electric motor/generator.
