• the present invention relates to a powertrain comprising a variable speed transmission device and a hybrid type of motor vehicle using such a group.
• a hybrid-type vehicle comprises a powertrain that uses alone or in combination, as a traction / propulsion drive mode, an internal combustion engine with a variable speed transmission device, and a rotary electric machine connected to an electrical source, such as one or more batteries.
• This combination has the advantage of optimizing the performance of this vehicle, including reducing emissions of pollutants into the atmosphere and reducing fuel consumption.
• the use of the electric machine is preferred.
• the engine is used to move this vehicle for uses where high driving power and a long operating autonomy are required.
• a powertrain in particular for a hybrid vehicle, with a variable speed transmission device comprising an epicyclic motor gear train with a sun gear and a each connected to the shaft of the heat engine by a controlled-control coupling and a fixed part of the vehicle by a unidirectional coupling and another epicyclic gear train connecting the epicyclic engine train to a motion transmission path to a driving axle of the vehicle.
• the two controlled-control couplings are in a position such that the speed and the engine-torque of the motor shaft is not transmitted to the crown and the planet.
