Embodiment Construction

[0020] refer to Figure 1 to Figure 3 The embodiment of the chainless bicycle of the present invention will be further described.

[0021] Such as figure 2 As shown in the chainless bicycle, the rear end of the vehicle frame is connected with the rear wheel 1 through the rotating shaft, the left and right sides of the vehicle frame are connected with the crank 7, and the crank 7 is connected with the connecting rod 6, and the connecting rod 6 is far away from the crank. One end of 7 is rotatably connected with the rotating disk 5 fixed on the rotating shaft, the rotating joint between the connecting rod 6 and the crank 7 is not on the same axis as the rotating disk 5, and the end of the crank 7 away from the connecting rod 3 is rotatably connected with a pedal 8. When one crank 7 rotates to the maximum upward angle, the other crank 7 rotates to the maximum downward angle; the crank 7 is rotatably connected to the vehicle frame through the rotation fulcrum one 17, and the con...

Abstract

The invention discloses a chainless bicycle which comprises a frame, a front wheel and a back wheel. The back wheel is a back wheel rotatably connected to the back end of the frame through a rotary shaft. The back end of the frame is rotatably connected to the back wheel through the rotary shaft, cranks are rotatably connected to the left and right sides of the frame, a connecting rod is rotatablyconnected to the cranks, and the end, far away from the cranks, of the connecting rod is rotatably connected to a rotating plate fixed to the rotary shaft. The bicycle is ridden by pedaling up and down, so that bend caused by excessive stress of hips, knees and ankles can be reduced.
