The invention relates to a tandem bicycle driving kinetic energy transmission middle axle device. The device comprises a middle axle, a rotatable axle sleeve is rotatably connected to the middle axle,and a bottom bracket is rotatably connected to the rotatable axle sleeve; one end of the rotatable axle sleeve is fixedly connected with a crankset, the other end of the rotatable axle sleeve is fixedly connected with at least one reverse flywheel, and the bottom bracket is located between the crankset and the reverse flywheel; and a one-way bearing is connected between the middle axle and the rotatable axle sleeve. The flywheel is integrated on the axle shaft device in the bottom bracket to reduce the length of a rear wheel driving flywheel and the length of a chain, so riding is labor-saving, and a bicycle driving structure is simple, and is attractive in appearance; and the one-way bearing is adopted, so the front pedal and the rear pedal can be different in pedaling frequency and operate independently without following rotation.

    本发明涉及一种双人自行车驱动动能传递中轴装置,包括中轴,中轴上可转动连接有可转动轴套,可转动轴套上可转动连接有五通;所述可转动轴套一端固定连接有牙盘,另一端固定连接有至少一个反向飞轮,五通位于牙盘和反向飞轮之间;所述中轴和可转动轴套之间连接有单向轴承。本发明所述的一种双人自行车驱动动能传递中轴装置,将一飞轮集成于五通内中轴装置上,减少后轮驱动飞轮和链条长度,使骑行更加省力,自行车驱动结构更加精简,外观美观;采用单向轴承,前后脚踏可踏频不同,单独运转不跟转。
