The invention provides a continuously variable transmission and a bicycle. The continuously variable transmission comprises a base, a first power wheel, a variable speed generation wheel, a speed regulation wheel and a first locking piece. The first locking piece is assembled on the speed change generation wheel in a sliding mode in the circumferential direction of the base and connected to the first power wheel in a sliding mode in the radial direction of the base, and the first locking piece is fixed to the speed change generation wheel in the radial direction of the base and fixed to the first power wheel in the circumferential direction of the base. Under the condition that the speed of the first power wheel is constant, the eccentric distance of the speed change generation wheel relative to the first power wheel can be changed by adjusting the speed adjusting wheel, so that the rotating speed of the speed change generation wheel is changed, stepless speed change is achieved, and the requirement for personalized adjustment of treading force during riding is met. In addition, non-friction continuous stepless speed change can be achieved through the stepless speed changer, the transmission torque is large, and the transmission efficiency is high. The speed can be changed in a static state, a rotating state and a riding state, speed regulation is convenient, the weight is light, and the size is small.
本发明提供了一种无级变速器及自行车,无级变速器包括基座、第一动力轮、变速发生轮、调速轮和第一锁止件。第一锁止件沿基座的周向方向滑动装配于变速发生轮且沿基座的径向方向滑动连接于第一动力轮,第一锁止件在基座的径向方向上与变速发生轮相互固定、以及在基座的周向方向上与第一动力轮相互固定。本发明可以在第一动力轮速度恒定的情况下通过调节调速轮改变变速发生轮相对第一动力轮的偏心距离,以改变变速发生轮的转动速度,实现无级变速,满足骑行时对踩踏力的个性化调节需求。此外,该无级变速器可以实现非摩擦连续无级变速,传递力矩大,传动效率高;在静止状态、旋转状态和骑行状态均可变速,调速方便,重量轻且体积小。
