The embodiment of the invention discloses a rear derailleur with a damping function and a bicycle, the rear derailleur with the damping function comprises a rear derailleur body, the rear derailleur body comprises a P joint seat and a chain guide component, the chain guide component comprises a chain guide plate, a main shaft and a reset piece, and a cut-off piece is fixedly arranged in a closed inner cavity; a damping fin used for dividing a gap between the closed inner cavity and the main shaft into a first flow cavity and a second flow cavity is fixedly arranged on the main shaft, and damping liquid is contained in the first flow cavity and the second flow cavity; a damping component is arranged on the damping fin and used for preventing damping liquid in the first flow cavity from entering the second flow cavity when the chain guide component rotates in the first direction and allowing damping liquid in the second flow cavity to enter the first flow cavity when the chain guide component rotates in the second direction. According to the embodiment of the invention, the damping component and the damping liquid are matched for use, so that the one-way damping function is realized, and the service life of the damping function is effectively prolonged.
本发明实施例公开了一种具有阻尼功能的后拨链器和自行车,具有阻尼功能的后拨链器包括后拨链器本体,后拨链器本体包括P关节座和链条导向构件,链条导向构件包括链条导向板、主轴、复位件,其中,密闭内腔固设有截断片;主轴上固设有用于将密闭内腔和主轴之间的间隙分割成第一流腔和第二流腔的阻尼片,其中,第一流腔和第二流腔内均容置有阻尼液体;阻尼片上设置有阻尼构件,用于在链条导向构件沿第一方向转动时阻止第一流腔内的阻尼液体进入第二流腔内,和用于在链条导向构件沿第二方向转动时允许第二流腔内的阻尼液体进入第一流腔内。本发明实施例实现通过阻尼构件与阻尼液体的配合使用,实现单向阻尼功能的目的,有效提高阻尼功能的使用寿命。
