DESIGN AND FABRICATION OF POWER STEERING SYSTEM USING WORM AND WORM WHEEL MECHANISM
ABSTRACT:
Since last few decades we have seen an ample amount of advancement in the automobile industry, especially in the cars. We also want to give some modifications to a conventional car in order to improve the viability of car or a four-wheel drive vehicle. An important factor that control the wheel drive is steering. In our project we are going to perform the power steering system with the help of worm and worm wheel gear in order to attain maximum working efficiency.
In our setup, the worm wheel diameter is maintained at maximum for attaining the easiness of the system. Due to this variable dimensions the rotations of wheel which is attached along with the steering shaft drives the worm gear in high extent so the wheels are aligned due to the little positioning of the steering. This system is one of the compact and simple system which is needed for modern environment.
INTRODUCTION:
Power steering systems are probably the most used servo system by the common man, even though most users never give it a second thought. The first power steering unit was invented by Francis W. Davis in the mid 1920’s, but was not introduced in passenger cars until 1951. This system was of the type: ball and nut, and is still in use in vehicles with higher steering forces, typically larger trucks.
The predominant system used today is of the type: rack and pinion, which was introduced in the late 1960’s in medium performance sports cars. There are several different power assisted steering, PAS, solutions for passenger cars on the market today. The most common is the rack and pinion solution with a constant flow controlled pump, Hydraulic Power Assisted Steering – HPAS system. More recently an Electric Power Assisted Steering, EPAS system, was introduced in smaller cars. We have planned to create the mechanically operated one called worm and worm wheel power steering system.
WORKING PRINCIPLE
The experimental setup consists of steering wheel which is attached with the worm wheel and this wheel arrangement is coupled with the worm which is linked to the wheel arrangement.
When the steering wheel is tilted to a certain angle then it activates the worm wheel there by activating the worm which tends to change the position of the wheel due to the link attached with it. Here the dimension of the worm wheel is high when compared too normal existing one so by providing the little tilting huge rotation gets exerted in the worm wheel there by efficient control of the steering system is attained.
