摘要： Bicycle rear derailleur device (1) comprising a chain guide assembly (15) made up of two parts: a guiding cage (28) and a tension cage (32). It also comprises a movable member (18) coupled to a base member (10) via a linking member (13) to align the chain guide assembly (15) with the different sprockets. Said tension cage (32) carries a tension pulley (11), is pivotably coupled to the movable member (18) and is biased by a main spring or biasing member (17). The guiding cage (28) carrying a guiding pulley (14), and the tension cage (32) are both configured to move either jointly or independently of each other, such the distance between both pulleys (14, 11) is fixed or free respectively, varying as a consequence the chain tension. To do so, the guiding cage (28) is pivotally coupled to the tension cage (32) comprising between them coupling means (16) that selectively and reversibly make both cages united or not.

摘要： A bicycle rear derailleur has a mounting base, a moveable base, and a friction assembly. The moveable base has an axle. The friction assembly is mounted in the moveable base and has a driving disk, a driven disk, multiple rotating members, and a friction member. The driving disk is connected with the axle in a non-rotatable manner. The driven disk is rotatably and axially moveably mounted in the moveable base. Each disk has multiple curved rotating member guiding recesses. Each rotating member guiding recess of the driving disk has a depth decreased along a first rotating direction. Each rotating member guiding recess of the driven disk has a depth decreased along a second rotating direction. The rotating members are mounted respectively in the rotating member guiding recesses. The friction member is mounted in the moveable base in a non-rotatable manner and abuts the driven disk.

摘要： A derailleur 10, for moving a chain 60 to different sized sprockets arranged small to large in a sprocket nest 101 is disclosed. The derailleur 10 has a feed arm for directing the chain 60 onto one of multiple sprockets within the sprocket nest 101. The feed arm 11 is rotatably mounted at a pivot end on an angular pivot 12 and when the feed arm 11 rotates about the pivot 12 an opposite chain guide end of the feed arm 11 traces a path substantially parallel to a tangent to the outer periphery of the sprocket nest 101. The movement of the feed arm 11 is mechanically driven by a user command and is preferably moved by a connected rod or wire or cable 109. The guide end of the derailleur 10 has a chain guide, wherein the chain guide is a smooth surface or a roller or toothed roller. The derailleur 10 further has a chain slack take-up assembly having a pivotal take-up idler arm 20 for chain slack take-up, which is pivotably connected to the chain guide end of the feed arm 11. Preferably, the feed arm 11 and the take-up idler arm 20 share a chain guide and wherein the feed arm 11 and idler arm 20 are both spring loaded, preferably sharing the same spring 50, wherein the spring 50 biases both the feed arm 11 and idler arm 20, the spring 50 being connected to the idler arm 20 near the feed guide end and onto the guide arm 20 near the angular pivot 12 on the frame 110.
