[0006] The purpose of the present invention is to overcome the shortcomings of the existing continuously variable transmission technology that transmits small torque through friction, and to overcome the shortcomings of ordinary CVT continuously variable transmissions that cannot achieve zero-speed output when the internal combustion engine does not stop, and to provide a transmission that uses full gear meshing. The double ring gear eccentrically rotates continuously variable speed method, which has the advantages of simple structure, low cost and large transmission torque, and can ensure that the fuel engine always runs in the economical speed range, and the internal combustion engine does not stop. It can output at zero speed, and can gradually increase the output speed from zero speed to cruising speed, and can change the rotation direction of the output shaft when the input shaft of the continuously variable transmission mechanism does not change the rotation direction. If the fuel vehicle is equipped with the continuously variable transmission mechanism, it can improve the Fuel efficiency of fuel vehicles and reduction of pollutant emissions
