<p>PROBLEM TO BE SOLVED: To lessen the mechanical loss of a driving force transmitting mechanism and lessen the burden of a motor, in four-wheel drive, by coupling one hand of the first rotor and the second rotor constituting a first rotating electric machine and a second rotating electric machine to a front drive shaft and the other to a rear drive shaft. SOLUTION: An output shaft 1213 extended from the rotor 120 constituting a rotating electric machine 1200 is coupled with a front wheel drive shaft 913, and the front wheel drive shaft 913 is coupled with an axle shaft 931 which couples right and left front wheels 701 and 702 with each other through a differential gear device (front wheel diff device) 910. A rotor 1310 constituting the field of the rotating electric machine 1400 or the rotating electric machine 1200 is arranged coaxially around the rotor 1210, and this rotor 1310 is coupled with the output shaft 1340. The output shaft 1340 is coupled with a rear wheel drive shaft 953, and the rear wheel drive shaft 953 is coupled with an axle shaft 971 which couples the right and left rear wheels 703 and 704 through a differential gear device (rear diff. device) 950 of the same structure.</p> |
