Abstract— The number of automobiles has seen an alarming rise in the recent years. In the year 2014, the number of road vehicles produced annually increased to 87.23 million vehicles from around 40 million in 2000. This shows that production has increased to more than twice the volume in only 14 years. This has also caused a rise in the pollution levels. Global CO2 levels are on the rise due to increased pollution, contributing to the greenhouse effect. Hence it is very important to reduce our dependency on gasoline driven vehicles. Electric vehicles are a good alternative to these. The advent of electric vehicles is marred by factors like unavailability of charging stations and most importantly not being able to match the performance parameters offered by gasoline driven vehicles. Hence a driveline setup has been designed to increase the performance parameters like gradeability and top speed of an electric moped to set it at par with the gasoline powered mopeds available on the market. In this report we will focus on the design considerations, working principle and the mechanism for the said driveline as well as the design calculations and the CAD model.
Keywords— automatic, centrifugal clutch, drive train, electric vehicles, freewheel, mopeds, transmission.
