Driving device for electric vehicles

A driving apparatus for an electric vehicle having drive shafts, a differential, and wheels, the driving apparatus comprising:

• a first wheel on one side and a second wheel on another side of the driving apparatus;
• a first drive shaft connected to the first wheel on the one side and a second drive shaft connected to the second wheel on the other side;
• a differential connected to the first and second drive shafts;
• a first motor having a first motor shaft arranged parallel to the first drive shaft and connected to the differential and the first and second wheels and configured to transmit driving torque to the first and second wheels;
• a second motor having a second motor shaft arranged parallel to the second drive shaft and arranged to face the first motor coaxial with the first motor shaft;
• a first reduction mechanism including a first planetary gear set coupled to the first motor shaft and having first, second, and third rotation elements, configured to reduce speed input from the first motor and to output a first torque;
• a second reduction mechanism including a second planetary gear set coupled to the second motor shaft and having fourth, fifth, and sixth rotation elements, configured to reduce speed input from the second motor and to output a second torque;
• a third reduction mechanism including an output gear fixed to an output side of the first reduction mechanism and a differential ring gear of the differential externally engaged with the output gear;
• and
• a power disconnector between the first motor shaft of the first motor and the output side of the second reduction mechanism configured to selectively connect and disconnect power between the first motor shaft and the second reduction mechanism.
