<p>A drive system for electrically powered vehicles where a specifically shaped flywheel (22) is driven by a motor (20). A friction wheel (26) engages the flywheel (22) to provide the driven output. The flywheel (22) is preferably of a concave conical shape with the wheel (26) adapted to be moved angularly thereon to vary the transmission ratio. </p> |
