ABSTRACT:
In a multiple-speed hub for a bicycle or like vehicle, a driver is rotatably mounted on a shaft normally fixed on the bicycle frame. A hub shell whose axial ends are rotatably supported by the driver and the shaft respectively encloses a planetary gear transmission including a sun gear fixed on the shaft, an internally toothed ring gear and a planet carrier rotatable about the shaft axis, and a planet gear mounted on the carrier in simultaneous meshing engagement with the ring gear and sun gear. Two overrunning clutches are drivingly interposed between the ring and planet carrier respectively and the hub shell. A coupling member permanently rotating with the driver may be shifted between positions of torque transmitting engagement with the ring gear and the planet carrier by a manually operated slide partly received in a slot of the shaft and connected to the coupling member by springs which permit movement of the coupling member by cam faces on the planet carrier out of an accidental intermediate position of simultaneous torque transmitting engagement of the coupling member with the ring gear and planet carrier without simultaneous movement of the manually operated elements.
