The invention discloses a gear stepless speed change system with a double-transmission structure, which is applied to a bicycle and comprises a power input assembly, a speed regulation assembly, two sets of transmission assemblies, a clutch assembly and a power output assembly, the two transmission assemblies are used for connecting power transmission between the power input assembly and the clutch assembly, and the speed adjusting assembly is used for changing the transmission ratio of the transmission assemblies, so that the rotating speed of the power input end of the power input assembly is changed at a certain speed change ratio and transmitted to the power output end of the power output assembly through the transmission assemblies and the clutch assembly. The two transmission assemblies are arranged and used for being connected with power transmission between the power input assembly and the clutch assembly correspondingly, compared with single connecting rod transmission applied before, the dead point problem of a single connecting rod is solved, riding is smoother, and riding comfort and riding efficiency are improved.

    本发明公开了一种具有双传动结构的齿轮无级变速系统,应用于自行车,包括动力输入组件、调速组件、传动组件、离合组件和动力输出组件,其中:传动组件有两套,两套传动组件同步运动,两套传动组件分别用于连接动力输入组件与离合组件之间的动力传递,调速组件用于改变传动组件的传动比,使得动力输入组件的动力输入端的转速以一定的变速比变速经传动组件和离合组件向动力输出组件的动力输出端传递。本发明通过设置两套传动组件,且两套传动组件分别用于连接动力输入组件与离合组件之间的动力传递,相比于在先申请的单根连杆传动,克服了单根连杆的死点问题,使骑行更顺畅,提高了骑行的舒适性和骑行效率。
