Design and Fabrication of Zero Turn Vehicle

Abstract

In today?s world on road vehicle demand is increased due to increase in world population. This increase in number of on road vehicles causes people to face problems like car parking in crowded places. In modern era, the major characteristics of the vehicle like steer ability and handling become major serious problem. Car parking has become serious problem in the country. To overcome the problem an alternative solution is proposed and thus the concept of Zero Turn Vehicles has been introduced. The concept is to change wheel system instead of total steering system, which is more convenient for the vehicle. Zero turning is done by turning the drive wheels at same rate in opposite direction at lower speeds; the turning circle radius is greatly reduced and is almost equal to length of car. In this project frame has been made from square bar. Wheel has four dc motors for wheel rotation and four motors to change direction of each wheel. As the vehicle rotates 360 degree, it is very useful to turn the vehicle in narrow space, parking problems at malls, traffic signal point and back turning on narrow roads.
