Abstract
A drive apparatus for an electric-motor four-wheel drive vehicle includes first and second motors, first and second differential mechanisms, and a propeller shaft. The vehicle includes a first wheel pair including first left and right wheels and a second wheel pair including second left and right wheels and positioned on opposite side to the first wheel pair in a front-rear direction. The first and second motors are configured to output first output torque and second output torque, respectively. The first differential mechanism is configured to distribute the first output torque to a first torque-transmitting member coupled to the first left wheel and a third torque-transmitting member coupled to the propeller shaft. The second differential mechanism is configured to distribute the second output torque to the third torque-transmitting member and a second torque-transmitting member coupled to the first right wheel.
