The present invention concerns a device ( 1 ) for power transmission between an output ( 2 ) of a heat engine ( 3 ) and an axle ( 5 ) shaft ( 4 ) and a related power transmission method. Said device comprises an input shaft ( 10 ) connected to the output ( 2 ), an output shaft ( 14 ) connected to the axle shaft ( 4 ), first and second electrical machines ( 6, 7 ), and a mechanical assembly ( 12 ) assembling the input shaft ( 10 ), the output shaft ( 14 ) and the shafts ( 8, 9 ) of the two machines. In order to limit the dimension of the device, the assembly ( 12 ) consists of two planetary trains ( 65, 66 ) comprising common planet pinion cage ( 18 ) which drives axles ( 23 - 26 ) in contact with the planet pinion cage ( 18 ) and the planet pinions ( 19, 21 ) of said trains. Moreover, a first switching device ( 30 ) connects the shaft ( 8 ) of the first machine ( 6 ) either to the input shaft ( 10 ) or to an element ( 22 ) of one of the trains ( 65, 66 ) of the mechanical assembly ( 12 ). |
