The invention relates to a bicycle rear derailleur. The rear derailleur includes: a base member mountable to a bicycle frame; a movable member movably coupled to the base member; and a pivoting member rotatably coupled to the movable member. The rear derailleur also includes a chain guide assembly rotatably connected to the movable member via a pivoting member. The rear derailleur includes a damper device disposed within the movable member. The damper device is operable to apply a damping force to the chain guide assembly when the chain guide assembly is rotated. The damper device includes a friction member having a friction surface. A first portion of the friction surface is in frictional engagement with the pivoting member and a second portion of the friction surface is in frictional engagement with the movable member. A friction device is disposed within the movable member spaced apart from the biasing device in an axial direction of the pivot member.
本发明涉及自行车后拨链器。后拨链器包括:能安装到自行车车架的基座构件;能移动地联接到基座构件的可移动构件;以及能旋转地联接到可移动构件的枢转构件。该后拨链器还包括经由枢转构件能旋转地连接到可移动构件的链条引导组件。后拨链器包括设置在可移动构件内的阻尼器装置。阻尼器装置能操作成当链条引导组件旋转时向链条引导组件施加阻尼力。阻尼器装置包括具有摩擦表面的摩擦构件。摩擦表面的第一部分与枢转构件摩擦接合,摩擦表面的第二部分与可移动构件摩擦接合。摩擦装置设置在可移动构件内,在沿枢转构件的轴向方向上与偏压装置间隔开。
