Abstract
A driving device of an electric-motor four-wheel drive vehicle includes a propeller shaft, a first differential mechanism, a second differential mechanism, a first decoupling mechanism, a second decoupling mechanism, a first motor, and a second motor. The propeller shaft transmits power between front wheels and rear wheels. The first differential mechanism is disposed in a drive shaft of the front wheels. The second differential mechanism is disposed in a drive shaft of the rear wheels. The first decoupling mechanism decouples the first differential mechanism from the propeller shaft. The second decoupling mechanism decouples the second differential mechanism from the propeller shaft. The first motor is coupled to the propeller shaft via a part closer to the front wheels than the first decoupling mechanism or a part closer to the rear wheels than the second decoupling mechanism. The second motor is coupled between the first and second decoupling mechanisms.
