If a road were perfectly flat, with no irregularities, suspensions wouldn’t be necessary. But roads are far from flat. Even freshly paved highways have imperfections that can interact with the wheels of a car. These are the imperfections that apply forces to the wheels.
A bump in the road causes the wheel to move up and down perpendicular to the road surface. so in order to tackle these issues of forces, bumps …., We need a system which will absorb the energy of the vertically accelerated wheel, allowing the frame and body to ride undisturbed while the wheels follow bumps in the road.
And the job of a car suspension is to maximize the friction between the tires and the road surface, to provide steering stability with good handling and to ensure the comfort of the passengers.
The suspension of a car is actually part of the chassis, which comprises all of the important systems located beneath the car’s body.
These systems include:
The frame – structural, load-carrying component that supports the car’s engine and body, which are in turn supported by the suspension.
The suspension system – setup that supports the weight, absorbs and dampens shock and helps maintain tire contact.
The steering system – mechanism that enables the driver to guide and direct the vehicle.
The tires and wheels – components that make vehicle motion possible by way of grip and/or friction with the road
So the suspension is just one of the major systems in any vehicle.
And in the next post, we will talk about how it works with its components.
