Development in suspension system

INTRODUCTION:

The term suspension suggest supporting from above, as in suspension bridge or suspender seems the earliest form of suspension used on the roads did literally suspend the body of the horse-drawl carriage at the four corner by every flexible leaf spring with outer end that curved over and upward to join the shackle pins in the carriage frame.

In the modern automobile suspension plays a dual role. It suspends the body on the shock absorbing system and the same time maintains contact patches of four tyres in effective contact with the road surface. One can not overemphasize the importance of the second role. If we fell in this the driver can not control the vehicle. Rally drivers are well aware that effective road contact is sometime lost. They were safety harnesses and crash the helmets reduce danger form the eventuality and the back up crew carry host of spares to repair the damage. Even so good suspension system under normal condition keeps all four wheels in contact with road surface and makes it possible for a driver of avg. ability to keep the vehicle under satisfactory directional control. A bad suspension systems fells to do under identical road conditions.

It is perfectly logical therefore to begun our analysis of suspension systems from the bottom since the cars four areas of contact with the road surface made by the tyres are so vital to behavior of vehicle in motion.
