Planetary change speed bicycle hub gearing

The self contained change speed control for use on a bicycle has a drive (2) and a hub body (3) rotatably supported on a fixed shaft (1). Two planetary gears (4,5) are arranged on a drive transmission path extending from the drive (2) to the hub body (1). The planetary gears include planet gears (11...

Zusammenfassung:	The self contained change speed control for use on a bicycle has a drive (2) and a hub body (3) rotatably supported on a fixed shaft (1). Two planetary gears (4,5) are arranged on a drive transmission path extending from the drive (2) to the hub body (1). The planetary gears include planet gears (11b,12b;13b,14b) meshed with sun gears switchable through externally controllable one way clutches between a state of free rotation relative to the fixed shaft (1) and a state of being locked to the fixed shaft. The controls of the one way clutches acting on the sun gears are effected by relative positional relations between projections formed on the fixed shaft and control sections formed on a control shiftable on peripheral surfaces of the fixed shaft.
