Abstract:
The present invention relates to a powertrain for a motor vehicle comprising a thermal engine (10), a variable-speed transmission device (14) including an engine epicyclic gear train (26) with a sun gear (36) carried by a hollow shaft (42) and a crown gear (56) carried by a hollow shaft (62) surrounding hollow shaft (42) of the sun gear, the sun gear and the crown gear are each connected to shaft (12) of thermal engine (10) respectively by a controlled clutch (28 and a second controlled clutch 30) and to a fixed part (48) of the vehicle by a one-way clutch (32 and 34), and a track (126 and 128) for motion transmission to a drive axle (16). According to the invention, the powertrain comprises in addition to the first and second controlled clutches a controlled connection (132) between the two hollow shafts (42 and 62).
