Four Wheel Steering System (4WS)

Description

This project is a Prototype model of “Four Wheel Steering System (4WS)”. This is a prototype model of steering system which is capable to reduce the overall turning radius of the vehicle, This mechanism possible by uses by the four-bar link, bell crank link.

These mechanisms are mechanical linkages coupling agents to connect the front steering axle to the rear steering axle. When the driver steers the car, the direction in which the front wheels turn is opposite the direction in which the rear wheels turn. This steering is quickly becoming the most common type of steering on cars, small trucks Military trucks and Forest jeep.

As all the 4 wheels can be steered in this system, the result is that Inside wheel turns at a smaller radius, hence the inside wheel turns at a steeper angle than the outside wheel. The intention is to avoid the tires to slip sideways when following the path around a curve. Thus the vehicle can be controlled more effectively especially during cornering and parking. Also, this system does not affect the overall speed of the vehicle.

Our design uses extremely simple ideas and mechanisms to achieve a complex set of actions and is intended to imitate the actions of the operators. Here, we have developed a small prototype of manually moving four wheels steering system.

Key Words: Bell-crank mechanism, Linkage, wheels, tearing etc.
