Zero Radius Turning Vehicle

Abstract

In modern era, the characteristics of the vehicle like steer ability and handling have become major aspects, conventional steering involve either the Ackerman or Davis steering system which has disadvantage that it can't take minimum radius turn. Providing zero turn steering without any compromise in steer ability and handling of the vehicle is a major concern for automakers. The main intention is to improve the zero turn steer ability of the vehicle without wheel wandering problems. The number of vehicles is continuously increasing. It causes the problem of traffic congestion, pollution (noise and air). To overcome problem like vehicle maneuvering on narrow roads and during parking this system has been proposed. Zero turn steering gives much better maneuverability and control on the vehicle. We have developed an innovative idea about four wheel steering design to implement a mechanism that can take minimum radius turn about its gravitational axis. Zero turning is done by turning drive wheels at the same rate in opposite direction. By steering the rear wheels in the direction opposite the front wheels at low speeds, the vehicles turning circle radius is reduced.
