Abstract
The invention includes first and second motors, first and second differential mechanisms, and first to eighth decoupling mechanisms. The first and second motors transmit power to left and right wheels. First differential mechanisms distribute the power from the first and second motors. The first and second mechanisms are interposed between the first differential mechanism and the left front wheel and between the differential mechanism and the left rear wheel. The third and fourth decoupling mechanisms are interposed between the first motor and the first decoupling mechanism and between the first motor and the second decoupling mechanism. The fifth and sixth decoupling mechanisms are interposed between the second differential mechanism and the right front wheel and the right rear wheel, respectively. The seventh and eighth decoupling mechanisms are interposed between the second motor and the fifth decoupling mechanism and between the second motor and the sixth decoupling mechanism.
