Estimating the term…
The present invention is a powertrain for a hybrid vehicle, comprising a driving/receiving machine (20), a thermal engine (10) and engine shaft (12), a speed variation device (14) including an engine epicyclic gear train (24) with a sun gear (34) and a crown (42) which are each connected to the engine shaft (12) by an engine controlled coupling (26, 28) and to a fixed part (40) of the powertrain by a one-way automatic coupling (30, 32). A planet gear carrier (46) and a machine epicyclic gear train (60) are arranged on a shaft (62) substantially parallel to engine shaft (12). The planet gear carrier comprises a sun gear (64), a crown (72), a planet gear carrier (68) and an epicyclic gear train controlled coupling (88). The speed variation device (14) comprises a device (94) for connecting/disconnecting electric machine (20) with machine epicyclic gear train (60).
