INFINITELY VARIABLE TRANSMISSION WITH FREE WHEEL POWER DIVIDER TRAIN AND METHOD OF OPERATION THEREOF

摘要

Infinitely variable transmission (1) with epicyclic gear train (30) power divider which mechanically connects a heat engine and two electrical machines (60, 70) exchanging electrical power with each other, transmission in which the mechanical power of the engine is distributed over a level of an input element of the train (33) between a first power channel where it is taken by a first electrical machine (60), and a second power channel, where it is connected to the mechanical power of the second electric machine (70), and is grouped on an output element of the train from which it is transmitted to the wheels of the vehicle on a variable transmission ratio depending on the electrical power exchanged between the two electrical machines, characterized in that the connecting shaft (31, a) of the heat engine with an input element of the train (31) cooperates with a freewheel (50) which provides support for the train (30) c a casing (10) is relayed to the heat engine when the latter is at a standstill.
