The invention discloses a clutch type chain wheel driving mechanism. The clutch type chain wheel driving mechanism comprises a wheel shaft, a side end disc, a chain wheel sleeve, an inner sleeve, an elastic gasket and a shifting button; re flange pieces are arranged on the inner side of the elastic gasket; the flange pieces are perpendicular to a gasket body; protruding elastic pieces a arranged on the flange pieces; the protruding elastic pieces can effectively limit the shifting button; when a rider rides forwards, the protruding elastic pieces on the flange pieces of the elastic gasket can ensure that the shifting button completely enters teeth of an inner gear ring of the side end disc; and when the rider stops riding, the protruding elastic pieces on the flange pieces of the elastic gasket can enable the shifting button to completely return to an initial position of a elastic gasket side and stably keep the shifting button at the initial position of the elastic gasket side.
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;弹性垫圈内侧设置有翼缘片,翼缘片与垫圈本体垂直设置,在翼缘片上设置有凸起弹性片,该凸起弹性片能够对拨扭起到有效的限位作用;当骑行者向前骑行时,弹性垫圈的翼缘片上的凸起弹性片能保证拨扭完全进入到侧部端盘的内齿圈齿牙;当骑行者停止骑行后,弹性垫圈的翼缘片上的凸起弹性片能够使拨扭完全退回到弹性垫圈侧初始位置并稳定的保持在弹性垫圈侧初始位置。
