Drivetrain for an electric vehicle

A drivetrain for an electric vehicle comprising:

• a motor;
• a pair of drive shafts, coupled to left and right drive wheels of the vehicle, respectively, one of which passes through the motor;
• and
• a transmission mechanism arranged coaxially with the pair of drive shafts for reducing rotational speed of the motor and for transmitting rotation at reduced speed to the pair of drive shafts, said transmission mechanism comprising:
• a first planetary gear unit having a first gear element coupled to the motor, a second gear element coupled to one of the drive shafts, and a third gear element, said first planetary gear unit increasing torque transmitted to the first gear element and then transmitting increased torque to the second gear element and transmitting torque in reverse direction between the second and third gear elements;
• and
• a second planetary gear unit having a fourth gear element coupled to the third gear element of the first planetary gear unit, a fixed fifth gear element, and a sixth gear element coupled to the other of the drive shafts, said second planetary gear unit transmitting the torque to the sixth gear element by reversing direction of torque received by the fourth gear element.
