The present invention relates to a powertrain for a hybrid type motor vehicle comprising a driving/receiving machine (20), a thermal engine (10), a speed variation device (14) including an engine epicyclic gear train (24) with a sun gear (34) and a crown (44), each connected to engine shaft (12) by a controlled clutch (26, 28) and to a fixed part (42) of the powertrain by a one-way clutch (30, 32) and a planet gear carrier (48), another machine epicyclic gear train (58) comprising a sun gear (56), a crown (66) and a planet gear carrier (60) connected to a device (79) for motion transmission to a drive axle (16), and a rotating motion transmission track for the link between the engine shaft and the motion transmission device. The invention, motion transmission track (90, 124) comprises a controlled link (80, 94, 134) between engine shaft (12) and at least one of elements (48, 56, 60, 66) of one of epicyclic gear trains (24, 58).
