Description

technical field

[0001] The invention relates to the driving technology of a wheeled device, in particular to a bicycle. Background technique

[0002] Bicycles have been around for over 200 years and have undergone many changes. In 1885, the British invented a bicycle with the same size as the front and rear wheels, and placed the sprocket with crank and pedals in the middle of the front and rear wheels. The person pedals, the crank drives the sprocket, and the sprocket drives the rear wheel to rotate through the chain to drive the bicycle forward. People's feet push down on the pedals, the pedals make a circular motion, and the mode that the sprocket drives the bicycle forward through the chain has not changed so far. This driving mode is widely used in wheeled devices such as bicycles and human-powered tricycles.

[0003] Now analyze the efficiency problem of the pedal sprocket drive system. please see figure 1 , figure 1 It is a schematic diagram of the force anal...
