| 摘要 |
The invention relates to a hybrid transmission for a motor vehicle provided with a heat engine and an electric drive machine (7), comprising two concentric primary shafts (1, 6), which are respectively connected to the heat engine and electric machine and each of which supports at least one intermediate drive (4, 8, 9) on a first secondary shaft (10) connected to the wheels of the vehicle via a differential (16) and a second secondary shaft (19) sending the motion of a primary shaft to the differential (16), characterized in that said transmission has a first coupling means (C1) between the two primary shafts (1, 6) that is capable of occupying at least three positions in which: - the heat engine is uncoupled from the drive train connecting the electric machine (7) to the wheels, or coupled thereto by means of the second secondary shaft (position 1); - the primary shaft connected to the heat engine (1) is coupled to the first secondary shaft (10) in order to drive the wheels with or without the support of the electric machine (position 2); and - the primary shaft connected to the heat engine (1) is coupled to the primary shaft connected to the electric machine (6), such as to add the respective torques thereof in the direction of the wheels (position 3). |
