Construction and performance of Four-Wheel Steering System of long chassis vehicle.

Abstract

Vehicles with a long wheelbase such as trucks and buses often have trouble negotiating tight and congested turns. In such cases four-wheel steering system can be employed to assist in reducing the turning radius of the vehicle. This includes steering over all of the 4 wheels instead of 2 wheels as in the present world. This has led to greater comfort for the driver to drive the vehicle whether it comes to taking a turn or it comes to changing lane over the highway. Four-wheel steering system also known as Quadra Steering System controls all the 4 wheels while turning there are multiple components which are required for this steering system design. This system uses gear mechanism to steer the vehicle’s rear wheels along with the front wheels thereby enabling the vehicle to turn fasted and more efficiently. Four-wheel steering technology is beneficial because it increases the vehicle’s steering response time and helps keep the vehicle stable at higher speeds. With all four wheels steering, instead of only the front two, this technology offers unprecedented control and maneuverability. It advances its stability and control at higher speed, neutral steering, maneuverability, turning radius. In this project is made to make a cost effective and efficient mechanism of four-wheel steering using Electric DC motor, gear pinion and required parts. It allows the driver to change from two-wheel to four-wheel according to its requirement
