Abstract

La présente invention concerne la présente invention concerne un véhicule terrestre, qui comprend une transmission infiniment variable (IVT) entre une première source d’entraînement et/ou une machine électrique et au moins une roue du véhicule, la transmission IVT étant agencée de manière que le rapport de réduction soit maximal lorsqu’aucun entraînement n’est activé. Figure 1 à publierThe present invention relates to a land vehicle, which comprises an infinitely variable transmission (IVT) between a first drive source and/or an electric machine and at least one wheel of the vehicle, the IVT transmission being arranged so that the reduction ratio is maximum when no drive is activated.
