Abstract: The experimental equipment for braking energy recovery based on common bicycles was designed and produced, with a cylindrical helical spring as energy storage component. Traditional friction braking of common bicycle and energy recovery braking of experimental bicycle were analyzed in order to get their mathematical models. The actual braking features were experimentally measured and contrasted. The experimental results show that braking process feature of energy recovery bicycle is similar to the traditional friction braking bicycle, and their feature curves have the same development tendency. Conclusions are made that the experimental braking energy recovery bicycles can meet the braking requirements of riders, and vehicle braking with braking energy recovery method using cylindrical helical spring can conform to comfort condition.

Key words: cylindrical helical spring, braking energy recovery, mathematical model, traditional friction braking, braking feature
