Document Type and Number:
Japanese Patent JP4884427
Kind Code:
B2
Abstract:
A multi-speed internal bicycle hub transmission assembly (12) includes a hub axle (24), a driver (25), a hub shell (26), a power transmission mechanism (14) and a shift control mechanism (16). The driver (25) and the hub shell (26) are rotatably supported to the hub axle (24). The power transmission mechanism (14) is disposed between the driver (25) and the hub shell (26) for transmitting rotational power from the driver (25) to the hub shell (26). The shift control mechanism (16) includes a shift controller (18) and a positioner (22). The shift controller (18) is movable in rotational directions relative to the hub axle (24) to a plurality of orientations. Each orientation of the shift controller (18) corresponds to selection of a corresponding one of plurality of power transmission paths of the power transmission mechanism (14). The positioner (22) is non-movable in the rotational direction relative to the hub axle (24) and is biased into contact with the shift controller (18).
