MOTOR FOR AN ELECTRIC BICYCLE

摘要

PURPOSE: A motor for an electric bicycle is provided to enable a user to work a pedal in a battery discharge state by mounting a first planetary gear and a second planetary gear. CONSTITUTION: A ring gear(130) is integrated with a housing(150) which supports the upper side of the motor. A first planetary gear(141) is engaged with the ring gear. A second planetary gear(142) is arranged on the lower side of the first planetary gear. The second planetary gear is larger than the first planetary gear and is separated from the first planetary gear. A clutch bearing(145) is insert-molded into the inner diameter of the second planetary gear. A rotation shaft(144) is pressed and mounted in the inner diameter of the first planetary gear. A fixing shaft(143) is mounted in the center of the rotation shaft and supports the shaft.
