The invention relates to a vehicle axle, comprising: - a differential; - a powertrain, comprising a first electric motor (EM1) and a second electric motor (EM2); - a first transmission element between the first electric motor and said differential, this first transmission element comprising a variable transmission ratio; - a second transmission element between the second electric motor and said differential; wherein the second electric motor is controlled so as to provide its maximum power during gear changes of the first transmission element, so as to compensate at least partially for the power loss inherent in the gear change.
La présente invention concerne un essieu de véhicule comprenant : - un différentiel ; -un groupe motopropulseur comprenant un premier moteur électrique (EM1) et un second moteur électrique (EM2) ; -un premier élément de transmission entre le premier moteur électrique et ledit différentiel, ce premier élément de transmission comprenant un rapport de transmission variable ; -un second élément de transmission entre le second moteur électrique et ledit différentiel ; le second moteur électrique étant commandé de manière à fournir sa puissance maximale pendant les changements de vitesse du premier élément de transmission, de manière à compenser au moins partiellement la perte de puissance inhérente au changement de vitesse.
