The main reason for this rise is the advent of mass production technologies for automobiles , making cars relatively cheap and affordable to everyone. In the year 2014, the number of road vehicles produced annually increased to 87.23 million vehicles from around 40 million in 2000. Th is shows that production has increased to more than twice the volume in only 14 years. Hence the auto industry is always on -the-rise. During the assembly of automobiles, be it everyday passenger cars or large commercial vehicles, tyres have to be assembled o n the car chassis at some point of t ime in the assembly. An average tyre+rim set for a commercial car weights around 10-12kg, and for heavy commercial vehicles it can go up to 25-45kg per tyre. Also the number of cars produced every day is very large. Almost always when the tyre has to be assembled, the vehicle is jacked i.e. it is raised to a height. Hence the tyre has to b...

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.

This study aims to redesign the steering knuckle in order to reduce the unsprung weight of a single seat All Terrain Vehicle (ATV) while retaining a satisfactory safety factor for better performance of the vehicle. A two step process has been used for the same. First step is modeling the knuckle as per the structural considerations and design constraints set by suspension, steering and brake assemblies & determination of loads acting on the knuckle. The second step is stress analysis using finite element software and design adjustments for reducing weight without compromising on the structural strength. According to the analysis results, material can be added to parts that are subjected to higher stress than the safety factor permits. Material can also be removed from low stress areas, thus, helping to reduce the component weight.
