The invention provides a bicycle variable speed control device. The bicycle variable speed control device comprises a base, a main shaft, a winding seat, a forward gear assembly and a backward gear assembly. The main shaft is rotatably connected with the base around the axis of the main shaft; the winding seat is arranged on the main shaft and rotates together with the main shaft; the gear-shifting assembly comprises a push rod which can push the main shaft to rotate in the gear-shifting direction. The reverse gear assembly comprises a release rod, a positioning ratchet, a positioning pawl, a release ratchet and a release pawl, and the main shaft can rotate in the reverse gear direction by operating the reverse gear assembly; the positioning ratchet and the releasing ratchet are arranged on the main shaft and rotate along with the main shaft, the base is connected with a positioning pawl and a releasing pawl, the positioning pawl is associated with the positioning ratchet, the releasing pawl is associated with the releasing ratchet, and the main shaft is limited to rotate in the reverse gear direction; and the release rod is rotatably connected with the main shaft and is used for triggering the release pawl and the positioning pawl, so that the positioning pawl is separated from the positioning ratchet and the release pawl is in contact with the release ratchet. The structure is simple and reliable, the cost is low, and the functional problems such as gear sliding are completely eradicated.
本发明提供一种自行车变速控制装置,包括底座、主轴、卷线座、进档组件和退档组件;主轴绕自身的轴线与底座可转动地连接;卷线座装于主轴上,与其一起转动;进档组件包括推杆,可推动主轴朝进档方向转动;退档组件包括释放杆、定位棘齿、定位棘爪、释放棘齿和释放棘爪,操作退档组件可使主轴朝退档方向转动;定位棘齿、释放棘齿设于主轴上,随主轴一起旋转,底座上连接有定位棘爪和释放棘爪,定位棘爪与定位棘齿相关联,释放棘爪与释放棘齿相关联,限制主轴往退档方向转动;释放杆与主轴可转动地连接,用于触动释放棘爪与定位棘爪,使定位棘爪脱离定位棘齿并使释放棘爪与释放棘齿接触。本发明结构简单可靠,且成本较低,杜绝了滑档等功能性问题。
