Abstract
(EN) The disclosure concerns a vehicle powertrain (4) comprising; a first electric machine (5) and a second electric machine (6), a transmission (7) arranged to transmit torque from said electric machines to a pair of driven wheels (3) of a vehicle (1), where the first electric machine is drivingly connected to a first input shaft (8) of the transmission and a second electric machine is drivingly connected to a second input shaft (9) of the transmission, a first torque path for transmitting torque comprises only one gear ratio between the first input shaft (8) and an output shaft (10) of the transmission (7), and a second torque path for transmitting torque comprises two selectable and separately engageable gear ratios between the second input shaft (9) and said output shaft (10) of the transmission, and where the three gear ratios of the first and second torque paths are different from each other.
(FR) L'invention concerne un groupe motopropulseur de véhicule (4) qui comporte : une première machine électrique (5) et une seconde machine électrique (6), une transmission (7) agencée pour transmettre un couple desdites machines électriques à une paire de roues entraînées (3) d'un véhicule (1), la première machine électrique étant reliée en entraînement à un premier arbre d'entrée (8) de la transmission et une seconde machine électrique étant reliée en entraînement à un second arbre d'entrée (9) de la transmission, un premier trajet de couple, qui permet de transmettre un couple, comprenant un seul rapport de transmission entre le premier arbre d'entrée (8) et un arbre de sortie (10) de la transmission (7), et un second trajet de couple, qui permet de transmettre un couple, comprenant deux rapports de transmission sélectionnables et pouvant venir séparément en prise entre le second arbre d'entrée (9) et ledit arbre de sortie (10) de la transmission, les trois rapports de transmission des premier et second trajets de couple étant différents les uns des autres.
