<p>A variable ratio transmission includes an input and an output, having an expansible chainwheel. A first drive path is provided to ¢state! rotate the chainwheel and a second drive path is provided to expand the chainwheel. The first and second drive paths are connected to the input so that the second drive path has a mechanical advantage over the first to provide an increase in diameter of the chainwheel prior to its ¢station! rotation.</p> |
