摘要： A ratchet gear, particularly for driving hubs of bicycles, having a pawl mounted in a pawl carrier without the use of bolts. The head of the pawl is provided with a securing surface which, even when the pawls occupy the engaged position, is situated opposite an intercepting surface of the pawl carrier, in the peripheral direction about the pivot, so that the partly cylindrical bearing foot of the pawl cannot be moved out of the partly cylindrical bearing bushing to any great extent and it is impossible for the head of the pawl to become jammed between the pawl carrier and the gear carrier.

摘要： The driver in a three-speed bicycle hub may be coupled alternatively with the planet carrier or the ring gear of the planetary gear transmission in the hub shell by means of radial arms on a coupling sleeve which is shifted axially between terminal positions of engagement with the carrier and the ring gear respectively for highest and intermediate transmission ratio. The engaged ring gear may further be shifted axially by the coupling sleeve from its normal position against the restraint of a spring to establish a third, lower transmission ratio. The coupling elements of the planet carrier and ring gear are normally closer to each other than the axial length of the coupling sleeve arms. The radial arms cammingly cooperate with coupling elements on the planet carrier and/or the ring gear to shift the arms automatically into a terminal position from any intermediate position in response to relative rotation of the associated transmission members.

摘要： A derailler system for a bicycle including a sprocket system having a plurality of drive sprockets and a chain for driving a wheel of the bicycle at different speeds with the chain being shifted onto individual drive sprockets by movement of an idler sprocket. A movable carrier member has the idler sprocket rotatably mounted thereon for selectively shifting the chain and a guide system is provided for guiding movement of the carrier member along the path essentially parallel with the axis of the driven wheel. A shifting mechanism for actuating the guide system includes a shift lever enabling shifting of the movable carrier to a plurality of shifting positions corresponding with the drive sprockets and a cam follower member including a cam follower rotatably mounted on a first part of the guide system is arranged to engage a cam member mounted on a second part of the guide system which is movable relative to the first part. The shift lever operates through a transmission mechanism to effect rotation of the cam member relative to the second part in order to move the guide sprocket to any one of a desired plurality of positions. A first spring is connected to urge the cam follower into contact with the cam member thereby to move the movable carrier member along its path of travel whenever the cam plate is rotated and a second spring biasing the cam follower member to a position relative to the first part is also provided with the relative position being defined by a stop member on the cam follower member and by a cooperating counterstop member on the first part of the guide system.

摘要： In a multiple speed hub with coaster brake for a bicycle, unintentional jamming of the brake is prevented by the provision of novel pawl clutches interposed between a planetary transmission and the hub shell. The recesses of pawl carriers pivotally receiving the clutch pawls are circumferentially oversized to permit limited circumferential movement of each pawl between a driving position and an idling position.
