The invention discloses a bicycle with a center shaft fluted disc speed changer and an electric moped, and belongs to the technical field of machines. The center shaft fluted disc speed changer is installed at the center shaft position of the bicycle and the electric moped, and a chain is connected with a flywheel of a rear shaft wheel and driven disc teeth of a center shaft fluted disc speed changer assembly; two pedal rod rods with pedals are rigidly connected with two ends of a center shaft; a transmission gear can be engaged with different gear rings of the two disc teeth at the same time,so that a chain wheel of the wheel can be driven through the chain, and the purpose of driving is achieved; because the disc teeth are divided into a driving fluted disc and the driven fluted disc, acertain axle distance exists between the two fluted discs, each disc tooth is provided with a gear ring composed of a plurality of teeth distributed in different diameters, if a plane passing throughthe axes of the two fluted discs is used for cutting out the cross section, the distances between the cross sections of the gear rings of the two fluted discs and the axes are equal in pairs, a sliding block hinge shaft restrained by a connecting rod hinge shaft at the other end moves, and the effect of gear replacement is achieved.

    带有中轴齿盘变速器的自行车及电动助力车,属于机械技术领域。是将中轴齿盘变速器安装在中轴部位的自行车及电动助力车,链条连接后轴车轮的飞轮与中轴齿盘变速器组件的被动的盘齿齿牙上;带有脚踏板的2个踏板杆杆与中轴的2端刚性连接;传动齿轮会同时齿合2个盘齿的不同的齿圈处,也就能通过链条来驱动车轮的链轮,以达到行车的目的;由于盘齿被分为主动齿盘与被动盘齿,两个齿盘彼此之间存在一定的轴距,在每一个盘齿上都有多条不同直径分布齿牙所组成的齿圈,如果使用通过2个齿盘轴线的平面来截取截面,所获得的2个齿盘的齿圈断面距轴线的距离满足俩俩相等,使得被另一端连杆铰轴约束的滑块铰轴运动,达到更换档位的作用。
