摘要： The following technical means are provided in order that change of chains can be performed with a minimum moving distance of a guide pulley, a change gear efficiency and a change gear controllability are improved and the change gear mechanism is prevented from projecting. In front of a multi-stage sprocket (2), a link base (8) of a pantagraph link mechanism (12) is supported by a chain stay (7), an internal link (9) and an external link (10) are extended rearwardly from the link base, a chain guide (15) is rotatably supported on a movable member (11) connected to the rear end portions of these links in a manner to be resiliently biasing, and a guide pulley movement control means (18) is provided, so that when the pantagraph link mechanism (12) is deformed, a guide pulley (13) of the chain guide (15) moves inwardly in a direction of a hub axis, and simultaneously, moves obliquely and downwardly in the forward direction, substantially along one of the radii of the aforesaid multi-stage sprocket (2).

摘要： A rear derailleur is provided which is capable of rationally solving a substantial problem of a conventional rear derailleur of this kind provided with a so-called double tension mechanism in which, the larger the diameter of a sprocket around which a chain is passed becomes, the closer the position of a guide pulley with respect to the sprocket becomes, and having improved gear-shifting performance. In this rear derailleur, a chain guide (25) having a guide pulley (39) and a tension pulley (40) is supported pivotably on a rear end portion of a control mechanism (23) having a front end portion supported pivotably at the front side of a multistage sprocket on a bicycle frame (22), the control mechanism being urged clockwise around a first lateral shaft (34) with respect to the bicycle frame, the chain guide being urged clockwise around a second lateral shaft (41) with respect to a chain guide support portion of the control mechanism.

摘要： A rear derailleur assem bly for mounting to a bicycle, wherein the bicycle includes a frame, includes an upper body for operationally engaging the rear derailleur assembly to the frame. The rear derailleur assembly also include a chain cage for engaging a chain of the bicycle; a controller pivotally connected to the upper body; and a lower body operationally connected to the chain cage, pivotally connected to the controller, and pivotally connected to the chain cage. The lower body includes a damper assembly for providing rotational resistance as the chain cage rotates in a first direction about the pivot axis.

摘要： The present invention is a derailleur comprising: a base plate disposed between the perimeter of a drive sprocket nest and a pedal sprocket; a chain guide attached to said base plate for moving a chain laterally causing said chain to move form sprocket to sprocket in a sprocket nest; a chain guide surface included in said chain guide for causing said chain to contact over ½ the perimeter of said pedal sprocket decreasing the likelihood of the chain slipping off said sprocket; and, a tension member attached to said base plate for removing slack in a chain as the chain moves from a larger sprocket to a smaller sprocket.

摘要： A bicycle derailleur gear shifting system having a rotatable handgrip actuator coupled with a derailleur shifting mechanism through a control cable system so as to control the derailleur. The derailleur (50) includes an arcuate cable entraining surface (78) which substantially reduces the variation and magnitude of the actuation ratio between control cable linear displacement and movement of the derailleur p-knuckle (88). A b-knuckle flange (160) militates against the derailment of the drive chain from the upper guide wheel while permitting maximum lateral flexing of the drive chain (48) during shifting between sprockets (46) on the freewheel. A rigid arcuate surface (174) may be provided as an extension of the b-knuckle (170) in replacement of a segment of a Bowden cable housing (38) to obviate the accumulation of water and foreign matter.
摘要翻译：一种自行车拨链器换档系统，其具有通过控制缆索系统与拨链器换档机构连接的可旋转手柄致动器，以便控制拨链器。拨链器（50）包括弓形缆索夹带表面（78），其基本上减小了控制缆线线性位移与拨链器p指节（88）的移动之间的致动比的变化和幅度。 b转向凸缘（160）有助于抵抗来自上导轮的驱动链的脱轨，同时允许驱动链（48）在自由轮上的链轮（46）之间的变化期间的最大横向弯曲。可以提供刚性弓形表面（174）作为b指节（170）的延伸部分，以替换鲍登缆索壳体（38）的一段，以消除水和异物的积聚。
