Abstract:
1. A drive unit for transmitting power to wheels of a motor vehicle comprising: an input driveably connectable to a first power source; a final drive gear set driveably connectable to the wheels; a motor/generator including a stator and a rotor arranged about an axis, the rotor being able to rotate about the axis and to move along the axis relative to the stator; a gear unit arranged about the axis and driveably connected to the gear set, for driving the gear set at a speed that is less than a speed of the rotor; and a coupler secured to the rotor for alternately coupling the rotor and the gear unit mutually and transmitting power therebetween, and decoupling the rotor and the gear unit mutually.
