The invention discloses a bicycle starting and stopping device. The device comprises a frame, a shaft pin, an axle and brake calipers, wherein the shaft pin is fixedly inserted into the frame, a bearing is fixedly installed on the axle, the shaft pin is fixedly inserted into an inner ring of the bearing, a fixed brake disc and a movable brake disc are coaxially installed on the axle, a forward one-way ratchet wheel is installed between the shaft pin and the fixed brake disc, and the brake calipers are installed on the frame. Through the design of the fixed brake disc, an energy storage wheel and an energy storage spring, the device does not influence a braking effect of the bicycle, a braking resistance torque can be increased in an energy storage process, and the device is a pure mechanical structure, works reliably and does not need frequent daily maintenance; and through the design of a locking clamping strip and a clamping groove, excessive operation of a rider is not needed in a working process of the device so that the device is simple, convenient and easy to use, parts of the device are simple and easy to obtain, and the influence on cost increase of a bicycle is small.
本发明公开了一种自行车起停装置,包括车架、轴销、车轴以及刹车卡钳,所述轴销固定插接在车架上,所述车轴上固定安装有轴承,所述轴销固定插接在轴承内圈中,所述车轴上同轴安装有定刹车盘与动刹车盘,所述轴销与定刹车盘之间安装有正单向棘轮,所述车架上安装有刹车卡钳。通过定刹车盘、蓄能轮以及蓄能弹簧的设计,该装置不影响自行车的制动作用,还能在蓄能过程中还可以增加制动阻力矩,本发明装置结构为纯机械结构,工作可靠不需要频繁的日常维护;通过锁止卡条以及卡槽的设计,此装置的工作过程不需要骑行者过多的操作,因此简便易用,本发明的零件简单易得,对自行车的成本增加影响较小。
