Abstract
A variable ratio gearbox is combined with a drive motor and an interactive control system. A coaxial shaft connects to a differential gear set to power an output shaft. The transmission has a drive shaft with an inner shaft and an outer shaft. A friction disk nonrotatably mounts to said outer shaft and a shifter connected to the friction disk moves the friction disk along the outer shaft. At least two cones engage the periphery of the friction disk and a differential gear set combines the rotation of the inner and outer shaft.
