Gear-based continuously engaged variable transmission

摘要: A method is described for changing gear-ratio by displacing at least one part of the engaging surface a composite gear (21) and aligning it to another (22), thus permitting complementary third (25) engaged surface, shift from different gear, while being constantly engaged. The can be employed in device, which used form gear-based, continuously engaged, variable transmission. Such transmission, enhanced by- combined with differential assembly appropriate gearing, provide rotational motion various speeds direction reverse as well zero motion.
