The invention relates to the technical field of transmission devices, and particularly discloses a gear shifting structure, a speed change system and a bicycle. The gear shifting structure comprises a transmission shaft which is at least partially hollow, a plurality of clutch transmission assemblies, a gear shifting rod and a driving assembly; the clutch transmission assemblies are installed on the transmission shaft and distributed at intervals in the length direction of the transmission shaft. The gear shifting rod is installed in the transmission shaft and can move in the length direction of the transmission shaft. A gear shifting part which can be connected with the clutch transmission assembly is arranged on the gear shifting rod; the clutch transmission assemblies have a retraction state and a use state, the driving assembly is used for driving the gear shifting rod to move, so that a gear shifting part on the gear shifting rod can be connected with any clutch transmission assembly, when the gear shifting part is connected with the clutch transmission assemblies, the clutch transmission assemblies are in the use state, and when the gear shifting part is disconnected from the clutch transmission assemblies, the gear shifting part is in the use state. And the clutch transmission assembly is in a retraction state.
本发明涉及传动装置技术领域,具体公开了一种换挡结构、变速系统和自行车,该换挡结构包括至少部分中空的传动轴、多组离合传动组件、换挡杆和驱动组件;多组离合传动组件安装在传动轴上,且多组离合传动组件沿传动轴的长度方向间隔分布;换挡杆安装在传动轴内,且换挡杆可沿传动轴的长度方向移动;换挡杆上设有可与离合传动组件连接的换挡部;离合传动组件具有回缩状态和使用状态,驱动组件用于驱使换挡杆移动,使得换挡杆上的换挡部可与任意一组离合传动组件连接,当换挡部与离合传动组件连接时,离合传动组件处于使用状态,当换挡部与离合传动组件脱离连接时,离合传动组件处于回缩状态。
