This paper unveils a new principle for automatic transmission, which will greatly simplify the current automatic transmissions and improve their efficiency. Unlike traditional automatic transmission based on torque converter/planetary gears or automatic transmission systems based on V-belt variable speed drives, this new approach does not rely on the gear ratio or the radius of the driving and driven wheel to change the speed ratio. The speed change in the new approach is to be achieved by an elastic belt on two fixed-diameter pulleys. The belt elongates in proportion to the load applied, and the driving pulley of the fixed diameter has to rotate more to accommodate the increased length of the belt due to the load increase. This means the speed of driven pulley will automatically reduce when the load increases. This pure mechanical drive system is self-sensing, self-adjusting, and fully automatic without electrical or hydraulic control. Based on this new kinematic principle, the simplest automatic transmission in the world can be designed, manufactured and used.
