The bicycle clutch chain wheel is characterized in that a cylindrical cam with convex blocks symmetrically arranged on the periphery is fixedly connected with one end of a five-way shaft sleeve through a middle through hole, a spline shaft on the outer side of a middle shaft is sleeved with a clutch disc, the clutch disc is fixedly provided with a rubber column through a first jackscrew, and the top end of the rubber column makes contact with the cylindrical cam; a spring piece is installed on the right side face of the clutch disc, a check ring arranged on the cylindrical shaft in a sleeving mode is arranged on the left side of the chain wheel, and the check ring is fixedly connected with the cylindrical shaft through a second jackscrew. The first square shaft section is sleeved with a left crank, the left crank is locked through a locking nut on the first screw, and a left pedal is installed at the other end of the left crank. Compared with a traditional bicycle chain wheel, meshing or separation of the clutch disc and the chain wheel can be automatically achieved, the pedals can rapidly pass through the stroke which is close to the lowest point and does not work conveniently, the bicycle chain wheel has more advantages in climbing and rapid acceleration, the power is greatly improved, and pedal driving is easier and more convenient.

    本发明公开了一种自行车离合链轮,外周对称设有凸块的圆柱凸轮通过中间的通孔与五通轴套一端固定连接,中轴外侧的花键轴上套装有离合盘,离合盘上通过第一顶丝固定装有橡胶柱,橡胶柱的顶端与圆柱凸轮接触;离合盘的右侧面安装有弹簧片,链轮的左侧为套装在圆柱轴上的挡圈,挡圈通过第二顶丝与圆柱轴固定连接;第一方轴段上套装有左曲柄,左曲柄通过第一螺杆上的锁紧螺母锁紧,左曲柄的另一端安装有左脚踏板。相比传统自行车链轮,可以自动实现离合盘与链轮的啮合或分离,脚踏板可以快速通过最低点附近这段不便做功的行程,在爬坡和急加速上更加具有优势,大大提高了功率,脚踏行驶更加轻松便捷。
