A motor (3) drives the pump (8) of a torque converter (7), the turbine (11) of which is connected to the crown (16) of a planetary gear train (13), the satellite carrier (18) of which is connected to the output of the transmission. The pump (8) is connected to the planet wheel (14) of the planetary gear train (13). The crown (16) is mounted on a free wheel (22) preventing rotation in the backward direction. During starting, the power passes via the planet wheel (14) into the gear train (13) which behaves as a mechanical reducer with the crown (16) immobilised by the free wheel (22). Then, the torque transmitted by the converter to the crown (16) exceeds the reaction torque strictly necessary, and the speed of the crown (16) becomes progressively equal to that of the planet wheel (14). The gear train (13) operates as an adder of the powers received mechanically at the planet wheel (14) and hydraulically at the crown (16). An automatic direct drive (23) is provided. The invention is used for minimising the control, the losses in the converter, the weight, cost and bulk.
