The invention relates to a hybrid transmission for a motor vehicle provided with a heat engine (1) and an electric driving machine (7), comprising: - two concentric primary shafts (1, 6), a first coupling means (5) between the two primary shafts (1, 6) able to occupy at least three positions in which the heat engine (1) is uncoupled from the kinematic chain connecting the electric driving machine (7) to the wheels, the heat engine (1) drives the wheel with or without extra contribution from the electric driving machine (7), and the heat engine (1) and the electric driving machine (7) are coupled so as to add their torques toward the wheels, and - a secondary shaft (10) connected to the wheels of the vehicle, supporting a second coupling means (13) capable of connecting either of the two secondary pinions (11, 12) on that shaft. This transmission is characterized in that it comprises an additional shaft (17) connected to an additional electric machine (18), able to supply an engine torque or a resisting torque to the transmission.

A motor vehicle drive system (1) comprises: a first electric drive machine (3), connected to a battery of accumulator cells, capable of providing mechanical drive energy and arranged in such a way that it can be coupled, in a way that may or may not be disengageable, to a differential (2) capable of driving a pair of driven wheels of the vehicle, - a second electric drive machine (4), connected to the battery of accumulator cells by a current inverter - rectifier which alternately allows the second machine (4) to deliver mechanical drive energy from the electrical energy of the battery and to convert mechanical energy transmitted to the second drive machine into electrical energy sent to the battery, - a combustion engine (5). The system further comprises a first set of gears (22-53, 38-53) provided with a first sliding sleeve (44,49), which, by moving the first sliding sleeve (44, 49), allows the second electric machine (4) to be coupled selectively either to the differential (2) or to the combustion engine (5).
