The invention discloses a clutch type chain wheel driving device which comprises a wheel shaft, a side end disc, a chain wheel sleeve, an inner sleeve, an elastic washer and a poking button. Teeth arearranged on the side end disc; the inner sleeve is fixedly mounted on the wheel shaft; the elastic washer is fixedly mounted on the inner end surface of the inner sleeve; the poking button is movablysleeved on the wheel shaft and is arranged on the inner side of the elastic washer; the chain wheel sleeve is installed on the inner sleeve through a bearing, a chain wheel is arranged at one end ofthe outer side of the chain wheel sleeve, a circle of cylinder is arranged at one end of the inner side of the chain wheel sleeve, a guide groove channel matching poking teeth of the poking button isformed in the cylinder wall of the cylinder, and the poking teeth of the poking button are located in the guide groove channel. When a bicycle is ridden forwards, the chain drives the chain wheel sleeve to rotate forwards, the guide groove channel of the chain wheel sleeve can drive the poking button to rotate forwards, a protruding elastic piece on the elastic washer can drive the poking button to move towards the side end disc when the poking button rotates forwards, and then the poking button is meshed with teeth of the inner gear ring on the side end disc to drive the side end disc to rotate.
本发明公开了一种离合式链轮驱动装置,包括轮轴、侧部端盘、链轮套筒、内套筒、弹性垫圈和拨扭;侧部端盘上设置有齿牙,内套筒固定安装在轮轴上,弹性垫圈固定安装在内套筒的内端面,拨扭活动套装在轮轴上并安装在弹性垫圈内侧,链轮套筒通过轴承安装在内套筒上,链轮套筒的外侧一端具有链轮,链轮套筒的内侧一端具有一圈圆筒,在该圆筒的筒壁上设置有用于与拨扭的拨齿配合的导向槽道,拨扭的拨齿位于该导向槽道中。向前骑行时,链条驱动链轮套筒正向运转,链轮套筒的导向槽道会带动拨扭正向转动,拨扭正向转动时弹性垫圈上的凸起弹性片会驱动拨扭向侧部端盘方向运动,进而实现拨扭与侧部端盘上内齿圈的齿牙啮合,驱动侧部端盘转动。
