  • Patent number: 9219393
    Abstract: The present invention relates to an electric drive system comprising an electric motor (10) arranged to rotate a drive shaft (16); a drive planetary gear configuration (70) being in driving engagement with said drive shaft (16) and an output shaft (50) rotatable relative to said drive shaft (16); and means for providing change in rotational speed of said output shaft (50), wherein said rotational speed changing means (80, 82) are disposed on opposite sides of the motor (10) respectively. The present invention also relates to a motor driven unit, for example a motor vehicle.

  • Patent number: 8343000
    Abstract: An electric drive system including an electric motor arranged to rotate a drive shaft. A differential includes a first planetary gear being drivingly connected to a first output assembly. A second planetary gear configuration is in driving engagement with the first planetary gear configuration via an output shaft. The second planetary configuration is drivingly connected to a second output assembly. The motor is disposed between the first and second planetary gear configuration. The first planetary gear configuration is arranged to co-act with the second planetary gear configuration so as to provide a differential function. The ring gears of the first and second planetary gear configurations are engaged via a reversing assembly for the differential function. Also, a motor driven unit, such as a motor vehicle.
