1. A dual-motor driving device for a vehicle, said dual-motor driving device comprising:
a transmitting unit including
an input axle that is rotatable, and
a sleeve that surrounds said input axle and that is rotatable relative to said input axle;
a first electric power unit including a rotor that surrounds said sleeve;
a second electric power unit including a rotor that surrounds said sleeve; and
a transmission switch unit including
at least one axle one-way clutch that is mounted between said input axle and said sleeve so that rotation of said input axle relative to said sleeve in a first rotating direction is prevented, and that rotation of said input axle relative to said sleeve in a second rotating direction opposite to the first rotating direction is permitted,
at least one first rotor one-way clutch that is mounted between said sleeve and said rotor of said first electric power unit so that rotation of said rotor of said first electric power unit relative to said sleeve in the first rotating direction is prevented, and that rotation of said rotor of said first electric power unit relative to said sleeve in the second rotating direction is permitted, and
at least one second rotor one-way clutch that is mounted between said sleeve and said rotor of said second electric power unit so that rotation of said rotor of said second electric power unit relative to said sleeve in the first rotating direction is prevented, and that rotation of said rotor of said second electric power unit relative to said sleeve in the second rotating direction is permitted.
