Abstract
The invention relates to a system for driving the drive wheels () of a vehicle, comprising two sets of electric motors () and casings () (left and right). Each of the casings () comprises an input pinion () which rotates interdependently with the rotor of one of the electric motors () as well as with a set of gears () driving the ring gear () of a planetary gear set (). The two planetary gear sets () are connected to one another by a connecting means () that rotates interdependently with each of the two sun gears () (inner planetaries). The planet carrier () of each of the planetary gear sets () rotates interdependently with a connecting means () of one of the drive wheels (). The two planetary gear sets () perform a double differential function. The invention also relates to a method for controlling the electric motors () that allows the drive system to be used as a torque converter. The drive system can be fixed to the chassis frame of the vehicle. In addition, the two casings () can be located in the wheel cages (). The connecting means () that rotates interdependently with the two sun gears () can be located inside the casing of the floor pan () of the vehicle. The two electric motors () can be located just behind the driven wheels ().
