    摘要: A variable ratio transmission includes an input and an output, having an expansible chainwheel. A first drive path is provided to rotate the chainwheel and a second drive path is provided to increase the diameter of the chainwheel upon application of a first input torque and to decrease the diameter of the chainwheel upon application of a second input torque of opposite sense to the first input torque. 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 rotation.
