    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.

    摘要翻译： 三速自行车轮毂中的驾驶员可以通过联接套筒上的径向臂与行星齿轮传动装置的行星架或行星齿轮传动装置的交替地联接在一起，该联轴器套筒在与接合套筒的接合位置之间轴向移动 载体和齿圈分别用于最高和中等传动比。 接合的环形齿轮还可以通过联接套筒从其正常位置轴向移动而抵抗弹簧的限制，以建立第三较低的传动比。 行星架和环形齿轮的联接元件通常比连接套筒臂的轴向长度更靠近彼此。 径向臂与行星架和/或环形齿轮上的联接元件凸轮地配合，以响应于相关联的传动构件的相对旋转，将臂自动地从任何中间位置移动到终端位置。

    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： 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.
