<p><P>PROBLEM TO BE SOLVED: To transfer a driving force to/from a pair of driven objects by using two driving sources and two differential devices connected with each other and individually and rotationally driving the driving forces of the driving sources. <P>SOLUTION: A first gear train 18a is turned into an operation state by an electromagnetic clutch CL, and electric motors M1, M2 are individually rotationally driven to turn in the rotating directions opposite to each other and driving torques are transferred to/from left and right rear wheels so that driving torques not smaller than the maximum driving force of the electric motors M1, M2 can be generated. A second gear train 18b is turned into an operation state by the electromagnetic clutch CL and the electric motors M1, M2 can be rotationally driven individually in the same rotating direction. By transferring the driving torque to/from the left and right rear wheels, the driving torque not smaller than the maximum driving force by the electric motors M1, M2 can be generated. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
