According to the transmission and a transmission method, the power generated from the motor or a pedal is outputted through a transmission device to a hub shell of the wheel. The output of the motor or other output of the motor which is subject to a reduction unit is used as the input of the transmission device. A one-way clutch to which the power of a driver is received in a one-way rotation manner is prepared to the other side of the input of the transmission device, while the input of the transmission device is commonly used as a carrier for a series of planetary gears in the transmission device. The carrier includes a multistage planetary gear coupled with the carrier by means of a pin; sun gears, engaged with their respective planetary gears of the multistage planetary gear and selectively confined to the shaft by an external speed change lever; a ring gear, engaged with the multistage planetary gear, for transferring a gear shifted power of the transmission device to the hub shell; a first speed pawl, coupled with the carrier by means of the pin, for directly transferring the power of the carrier to the ring gear by being coupled with gear teeth of the ring gear when every sun gear is not confined to the shaft by the external speed change lever; a transmission control unit, manipulated by the external speed change lever, for selectively confining the sun gears to the shaft. The ring gear and the hub shell are connected to each other with an output pawl, so that the power cannot be reversely inputted when the hub shell is rotated with a higher speed than the ring gear. | 02-02-2012 |
