2. ABSTRACT (IN APPX. 200 WORDS):

3. WHAT ARE THE EXISTING SYSTEM/S IN THAT PARTICULAR DOMAIN THAT YOU HAVE

SURVEYED (IN 500 WORDS):

Now a day’s most of the vehicles use the two wheel steering mechanism as

their main handling system. But the efficiency of the two wheel steering vehicle is

proven to be low compared to the four wheel steering vehicles. Four wheel

steering system can be employed in some vehicles to improve steering response,

increase vehicle stability while moving at certain speed, or to decrease turning

radius at low speed.

Four-wheel steering is a technologically, tremendous effort on the part of

automotive design engineers to provide near-neutral steering. In situations like

low speed cornering, vehicle parking and driving in city conditions with heavy

traffic in tight spaces, high speed lane changing would be very difficult due to

vehicle’s larger wheelbase and track width which brings high inertia and traction

into consideration. 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.

Four-Wheel Steering System is not a new technology but has it not gained

popularity over Two-Wheel Steering System even though experiments have

proved that it has excellent maneuverability, high stability and it is a solution to

over steer/under steer. If Four-Wheel Steering is a better replacement for age old

Two-Wheel Steering.

CONVENTIONAL STEERING SYSTEM

Usually during the steering of the vehicle, only the front wheels are steered towards right or left according to the requirement and the rear wheels are followers of the front wheels in this system. Generally it required conventional rack & pinion gear system for turning of both front wheels.

4. HOW IS YOUR PROJECT DIFFERENT FROM THE EXISTING SYSTEM (IN 500 WORDS):

5. WHY HAVE YOU CHOSEN THE TOOL/TECHNOLOGY/LANGUAGE FOR DEVELOPING

THIS PROJECT? (IN 500 WORDS):

The purpose of this system is to significantly reduce the turning radius of

the vehicle, thereby improving the performance of the vehicle during

competition. Many factors were taken into account when designing this

system. The foremost criteria of the design were the reduction of the turning

radius.

There are some points to describe my project different from existing

system-

1. Superior cornering stability.

2. Improved steering responsiveness and precision.

3. High speed straight line stability.

4. Notable improvement in rapid lane changing maneuvers.

5. Relative wheel angles and their control.

6. Smaller turning radius and tight space maneuverability at low speed.

We chose Auto Cad and Pro E software for designing of project and for force

analysis also.

We are also using various machines like lath, welding, drilling etc. for

assembling or machining purpose as required.
