Multi-speed transmission hub |
摘要 |
A multi-speed transmission hub for a bicycle having a multi-speed change mechanism and a braking mechanism for braking action by back-pedaling, in which first transmitting members of pawl shape serve to transmit the driving force from the speed-change mechanism to a hub shell and are urged by a pawl spring in the direction of being disengaged from first inner teeth of the hub shell, while, the transmitting members are adapted to be engaged with the first inner teeth by use of differential rotary speed between a gear frame and ring gear of the speed-change mechanism, when a driving member is normally rotated.
