Steering systems:-
The purpose of the steering system is to allow the driver to control the direction of the vehicle by turning the front wheels. Together with the suspension system, it plays an important role in ensuring easy, comfortable driving all the way from the low speed range to the high-speed ranges.
A good and efficient steering system has to ensure the following:
1. Excellent Maneuverability: When the car is cornering on a narrow, twisting road, the steering system must be able to turn the front wheels sharply yet easily and smoothly.
2. Proper Steering Effort: If nothing is done to prevent it, steering effort will be greater when the car is stopped and will decrease as the speed of the car increases. Therefore, in order to obtain easier steering and better feel of the road, the steering should be made lighter at low speeds and heavier at high speeds.
3. Smooth Recovery: While the car is turning, the driver must hole the steering wheel firmly. After the turn is completed, however, recovery- that is, the return of the wheels to the straight-ahead position- should occur smoothly as the driver relaxes the force with which he is turning the steering wheel.
4. Minimum transmission of Shock from Road Surface: Loss of steering wheel control and transmission of kickback due to road surface must not occur.
STEERING SYSTEM:-
The steering system converts the rotation of the steering wheel into a swiveling movement of the road wheels in such a way that the steering wheel rim turns a long way to move the road wheels a short way.
The system may allow the driver to use only light forces to steer a heavy car.
The rim of a 380 m.m diameter steering wheel moving four turns from full left to full right lock,it travels nearly 16 feet ,while the edge of a road wheel moves a distance of slightly more than 300 m.m.
If the driver swiveled the road wheel directly , he or she would have to push nearly 16 times as hard.
