Infinite variable transmission with power derivation for use in vehicle, has electrical machines separated by epicyclic train that coordinates with control units to establish two operating modes for transmission and to switch between modes

摘要

The transmission has constituent units that are distributed between two power lines connecting a thermal engine (1) to wheels (3) of a vehicle. Two electrical machines are separated by an epicyclic train (7). The engine, the wheels and the machines are connected to a reduction stage (11). The train coordinates with two control units (8, 9) to establish two operating modes for the transmission and to switch between the modes.
