The invention discloses a stepless speed change mechanism, and relates to the technical field of speed change transmission. According to the technical scheme, the device is characterized by comprising a first supporting part, a second supporting part, a cam rocker assembly and a variable-speed adjusting assembly, the cam rocker assembly comprises a cam, a rocker and a rocker supporting shaft, one end of the rocker is in contact with the surface of the cam, and the rocker supporting shaft is sleeved with the other end of the rocker; the rocker and the rocker supporting shaft are linked in the circumferential direction, and the rocker can move in the axial direction relative to the rocker supporting shaft; the cam is arranged in a conical shape in the axial direction. When the variable speed adjusting assembly drives the rocker to move in the axial direction, the axial contact position of the rocker and the cam is changed, so that the swing angle of the rocker is changed, and stepless speed change is achieved. The axial size can be optimized, so that the stepless speed change mechanism can be conveniently installed on a vehicle to achieve stepless speed change in the riding process, and riding experience is optimized.
本发明公开了一种无级变速机构,其涉及变速传动技术领域。其技术方案要点包括第一支撑部件、第二支撑部件、凸轮摇杆组件和变速调节组件,凸轮摇杆组件包括凸轮、摇杆和摇杆支撑轴,摇杆的一端与凸轮表面保持接触,另一端套设在摇杆支撑轴上;摇杆与摇杆支撑轴沿周向联动,并且摇杆能够相对于摇杆支撑轴沿轴向移动;凸轮沿轴向呈锥型布置;变速调节组件驱动摇杆沿轴向移动时,改变摇杆与凸轮的轴向接触位置,从而改变摇杆的摆角,实现无级变速。本发明能够优化轴向尺寸,从而便于安装至车辆上,来实现骑行过程中的无级变速,优化骑行体验。
