Infinitely variable power branching hybrid transmission for drive train of hybrid vehicle, has components distributed between lines to connect heat engine to wheels in parallel manner, and reverser axle provided in outlet of heat engine

摘要

The transmission has components distributed between a main power line and a power branching line for connecting a heat engine (M) to wheels (V) of a hybrid vehicle in a parallel manner using a connection unit constituted of three planetary gears (G1, G2, G3), a reduction stage (R) and two electrical machines (ME1, ME2) joining the power branching line. The power line links the gear (G2), and the power branching line links the gear (G2) by following the gears (G1, G3) associated to the electric machines. A reverser axle (G4) is provided in outlet of the heat engine.
