- satellites cooperate in meshing with a sun gear 104 which comprises a wheel 106 toothed externally and carried by a flange 108.
- This flange is fixedly mounted on a tubular shaft 1 10, said additional sun gear shaft, which surrounds, freely rotating but fixedly in translation, the machine shaft 92.
- the satellites also cooperate in meshing with a ring January 12 which comprises a wheel 1 14 toothed internally carried by a web 1 1 6 connected to a tubular shaft of crown 1 18.
- This shaft 1 18 surrounds the sun gear shaft 1 10 and further carries a sail 120 provided at its end with an externally toothed gear 122 which cooperates with the wheel 88 carried by the planet carrier 56 of the epicyclic motor gear train 26.
- the tubular shaft 102 of the planet carrier also carries an externally toothed wheel 126 on the end of a web 127 which cooperates with a toothed wheel 128 connected to the driving axle 1 6.
- This set of two toothed wheels thus forms a motion transmission path between the machine epicyclic gear train 90 and the axle 1 6.
- the ring 1 12 of this epicyclic gear train 90 also carries a controlled-control coupling 130 (actuator A3), here in the form of a double-acting synchronizer, making it possible to connect this ring, either to the sail 100 of the planet carrier 94, either at the fixed part 46 of the powertrain.

- This synchronizer is mounted fixed in rotation but free in translation on the shaft 1 10 so as to cooperate with a support blank 156 carried by a tubular sleeve 158.
- This sleeve surrounds the sun gear shaft 1 10 and is connected to the part fixed 46 of the powertrain by a unidirectional coupling 1 60, such as a freewheel.
- the freewheel has the same role as the first two. It is blocked on the fixed part 46 when at least one of the clutches 72 and 84 is in the engaged position, and that the clutch 146 is in the disengaged position. This situation occurs for three of the seven reports.
- the freewheel rotates, either if the engine is running and the clutch 146 is in the engaged position, or when the electric machine 22 is running for a forward gear, or when these two situations occur simultaneously.

- the pure electric mode on the short ratio is obtained when A3 is in position 1 and A5 and A4 in neutral position. In this mode the vehicle can be moved in pure electric mode forward and reverse.
- disk clutch coupling 30 of the ring 48 has been replaced by a controlled control coupling 30 'in the form of a single-action synchronizer 172 (actuator A2 ').
- This synchronizer is fixed in rotation on the motor shaft 12 but displaceable in axial translation under the action of a control means to move from a neutral position (position N) to an active position (position 1) where this synchronizer is connected in rotation with a connecting face 174 carried by the tubular shaft 54 of crown.
- This wheel 150 cooperates with a gear wheel 176 of machine carried by a web 178 mounted on a tubular shaft 180 which surrounds the tubular shaft 1 10 sun gear.
- the sleeve 158 is, as in Figure 1, connected to the fixed part 46 of the power unit by a unidirectional coupling 1 60 surrounding the tubular shaft 1 10 sun gear.
- a double-acting synchronizer which is placed on the tubular shaft 1 10 sun gear being fixed in rotation but free in translation.
- This synchronizer is placed between the tubular shaft 180 and the sleeve 158 and cooperates from a neutral position (position N) with a bearing surface 182 carried by the tubular shaft 180 (position 1) or with a surface support 184 carried the tubular shaft 158.
- tubular shaft 1 10 sun gear carries a gear 1 64 which cooperates with the input wheel 166 carried by the rotor of the machine 22.
- gear 1 64 which cooperates with the input wheel 166 carried by the rotor of the machine 22.

- the double action synchronizer thus cooperates, from a neutral position (position N), either with the bearing surface 182 carried by the tubular shaft 180 (position 1) or with the bearing surface 186 carried by the fixed part 46 of the group.
- the 10 reports are obtained for the same positions of the actuators.
- the transmission can be used in a parallel hybrid.
- the pure electric mode on the short ratio is obtained when A3 is in position 1 and A4 'in neutral position. In this mode the vehicle can be moved in pure electric mode forward and reverse.
- the pure electric mode on the long report is obtained when A3 is in position 2 and the actuator A4 'in position N. In this mode the vehicle can be moved in pure electric mode forward.
