Power Generation by Shock Absorber

Abstract

Abstract: In a country like India, two-wheeler vehicles are predominant over four wheelers. According to data taken from internet, around 20 million two wheelers were sold in 2017/18, as compared to 4 million four wheelers. And this demand keeps on increasing in India. Keeping this mind, a huge potential of energy is being wasted every day. This project is one of the methods to harvest those wasted energy. That’s why this project is under energy recovery. All the major advancements and break through has been done mostly on four wheelers. To name some energy recovery mechanisms, regenerative brakes, regenerative shocks, MGU-H, MGU-K. Even the companies like AUDI and BMW have started launching commercial vehicles which come with energy recovery systems. The main purpose of the dampers is to keep the tires in contact with the ground all the time. Other functions include to absorb the vibrations produced due to irregularities of the surface. This prototype aims to convert these vibrational energies into electricity which otherwise would have been wasted. In a way it can be called Regenerative dampers, which is completely mechanical in nature. This prototype uses a rack and pinion arrangement to convert the reciprocating motion of the bike front fork into a linear motion. The motor is coupled to a DC generator which produces electricity. Our main focus is on two wheelers so, the energy stored can be used to increase the engine efficiency as extra load on alternator is reduced. The aim for this prototype is to produce a current of 0.3A and 12 V (DC), which would be sufficient to charge the batteries and run other auxiliary system of a motorcycle.
