The invention discloses an electric bicycle chain wheel clutch driving method, which comprises a wheel axle, a motor end disc, a chain wheel, a clutch driving mechanism and a reset mechanism, whereinthe chain wheel is mounted on the wheel axle and can move along the wheel axle in the axial direction; the motor end disc is installed on the wheel axle, and a clutch meshing structure capable of being matched with the motor end disc and the chain wheel is arranged between the motor end disc and the chain wheel; the clutch driving mechanism is used for driving the chain wheel to move towards the motor end disc to be meshed with the motor end disc; the reset mechanism is used for driving the chain wheel to be separated from the motor end disc; in the riding state, the chain wheel is driven by achain to rotate forwards, the clutch driving mechanism drives the chain wheel to move towards the motor end disc to be meshed with the motor end disc, and then the chain wheel drives the motor end disc to rotate; and in a non-riding state, the reset mechanism drives the chain wheel to be separated from the motor end disc. The chain wheel is only in meshed transmission with a motor wheel in a riding state, so that the working time of the chain wheel is greatly shortened, and the service life of the chain wheel is prolonged. Moreover, the running noise of the chain wheel is reduced, and the condition of follow-up rotation is avoided.
本发明公开了一种电动自行车链轮离合驱动方法,包括轮轴、电机端盘、链轮以及离合驱动机构和复位机构;链轮安装在轮轴上,能够沿轮轴轴向移动;电机端盘安装在轮轴上,电机端盘和链轮之间具有能够相互配合的可离合啮合结构;离合驱动机构,用于驱动链轮向电机端盘移动与之啮合;复位机构,用于驱动链轮脱离电机端盘;骑行状态下,链轮受链条驱动正向转动,离合驱动机构驱动链轮向电机端盘移动与之啮合,进而链轮带动电机端盘转动;非骑行状态下,复位机构驱动链轮脱离电机端盘。链轮只有在骑行状态下才会与电机轮啮合传动,从而大大减少了链轮的工作时长,延长了链轮的使用寿命;并且减少了链轮运转噪音,避免了跟转的情况发生。
