Design & Fabrication of Four-Wheel Steering System

In the growing world, automobiles play a vital role In our lives. Our main motive here is to bring in the use of 4- wheel steering (All wheel steering) into common usage among car companies due to increase in traffics and congestions. Four wheel steering is preferable than two wheel steering systems because a multi-function four wheel steering system could improve directional stability at high speeds, sharp turning performance at low speeds, and parking performance of a vehicle. Once this concept come into use parking becomes very easy and driving in sharp turns make it much easier. Production cars are designed to understeer and rarely do they oversteer. If a car could automatically compensate for an understeer/oversteer problem, the driver would enjoy nearly neutral steering under varying operating conditions. Four- wheel steering is a serious effort on the part of automotive design engineers to provide near-neutral steering. Also in situations like low speed cornering, vehicle parking and driving in city conditions with heavy traffic in tight spaces, driving would be very difficult due to vehicle’s larger wheelbase and track width. Hence there is a requirement of a mechanism which result in less turning radius and it can be achieved by implementing four wheel steering mechanism instead of regular two wheel steering.While braking, a large amount of energy is lost in the form of heat. A regenerative braking system aims to utilize this energy instead of getting it wasted
