Abstract
There is desperate need to find an alternate power source to run the vehicles. This reasons leads to work on electric vehicles. In India, it has been noticed major part of urban air pollution is caused by auto rickshaw emissions as they are not maintained properly. So switching from conventional rickshaw to electric will significantly reduce this problem in urban areas. Continuously variable transmission (CVT) transfers power uninterrupted due to its infinite gear ratios. Moreover, it allows the motor to run at its optimum speed which ultimately reduces the current consumption. CVT available in current market is design to work efficiently with internal combustion engines. This CVT can be made compatible with pure electric power train by CVT tuning. This paper aims to study and analyses the effect on performance of CVT by varying the mass of flyweights. The driver and driven pulley RPM are measured using DAQ system. This data is then use to obtain gear ratio. The iterations are performed using two different mass of flyweights. The gear ratio verses pulley rpm graphs are compared. The result infers that as the flyweight mass is increase the engagement rpm decreases and up-shift rate increases. This enhances performance of CVT.
