The invention discloses a flywheel with a retaining groove for a motor of an electric bicycle, the flywheel comprises a flywheel retaining sheet, a connecting assembly and a hub, the connecting assembly is composed of a motor end cover and a flywheel, the motor end cover is fixed on the hub, the flywheel retaining sheet is located between the motor end cover and the flywheel, and the flywheel retaining sheet is fixed on the hub. The flywheel retaining sheet, the flywheel and the motor end cover are connected through threads, and the flywheel is provided with an anti-rotation groove. By means of the combined design of the flywheel retaining piece and the connecting assembly on the hub, when the electric bicycle is driven in an electric mode, the flywheel can be locked, meanwhile, the anti-rotation teeth on the flywheel retaining piece can be embedded into the anti-rotation grooves in the flywheel, the anti-rotation teeth have the effect of locking the anti-rotation grooves, and therefore the flywheel is limited and fixed, reverse rotation of the flywheel is avoided, and the service life of the flywheel is prolonged. And the problem that the flywheel is loosened and even falls off due to the influence of factors such as forward rotation tightening force and vibration on the flywheel is effectively solved.
本发明公开了一种电动自行车电机用的带止退槽的飞轮,包括飞轮止退片、连接组件和轮毂,所述连接组件由电机端盖和飞轮构成,所述电机端盖固定于轮毂上,所述飞轮止退片位于电机端盖和飞轮之间,所述飞轮止退片、飞轮和电机端盖之间通过螺纹衔接,所述飞轮上设有防转槽。通过轮毂上飞轮止退片以及连接组件的组合设计,当电动自行车电动骑行时,飞轮会锁紧,同时飞轮止退片上的防转齿会与飞轮内的防转槽嵌合,防转齿起到对防转槽锁止的效果,从而对飞轮进行限位固定,避免了飞轮反转,有效避免了飞轮受正向旋转的拧紧力和震动等因素的影响,造成飞轮会有松动甚至脱落的问题。
