The invention discloses a chainless bicycle transmission system which comprises a driving shaft, a front fluted disc and a rear fluted disc, and the front fluted disc comprises an embedded fluted disc and at least one concentric toothed ring arranged on the end face of the embedded fluted disc; the rear fluted disc comprises an embedded fluted disc and at least one concentric toothed ring arranged on the end surface of the embedded fluted disc; front spherical teeth are arranged at the front end of the driving shaft and are alternatively meshed with a concentric gear ring arranged on the front fluted disc, and rear spherical teeth are arranged at the rear end of the driving shaft and are alternatively meshed with a concentric gear ring arranged on the rear fluted disc; and the system further comprises a control assembly which is used for controlling and changing the meshing state of the rear spherical teeth and the rear fluted disc, and an adjusting assembly which is used for adjusting the relative position of the rear spherical teeth on the driving shaft. By optimizing the front fluted disc, the driving shaft and the rear fluted disc, the friction force in the transmission system is reduced, the transmission efficiency is improved, meanwhile, the structure of the transmission system is simplified, the production cost is reduced, and the universality is improved.

    本发明公开了一种无链条自行车传动系统,包括驱动轴、前面齿盘和后面齿盘,所述前面齿盘包括嵌齿盘及设置于嵌齿盘端面的至少一个同心齿环;所述后面齿盘包括嵌齿盘及设置于嵌齿盘端面的至少一个同心齿环;所述驱动轴的前端设置有前球形齿与设置于前面齿盘上的同心齿环择一啮合,所述驱动轴的后端设置有后球形齿与设置于后面齿盘上的同心齿环择一啮合,还包括用于控制改变所述后球形齿与后面齿盘啮合状态的控制组件及用于调整所述后球形齿在所述驱动轴上相对位置的调节组件。本发明通过对前面齿盘、驱动轴及后面齿盘的优化,降低了传动系统中的摩擦力,提高了传动效率,同时简化了传动系统的结构,降低了生产成本,提高了普适性。
