Car Suspension?

Yes we all have it, but do we really know what it is?

Here’s what the car suspension does: it’s supposed to maximize the friction that’s between the tires and the surface of the road. It does this to provide steering stability with good handling and to make sure that the passengers are comfortable. If there was a road that was perfectly and completely flat, then suspensions wouldn’t be necessary - at all.

If you know Newton’s Laws of Motion, then you know that all forces have both magnitude and direction. If there’s a bump in the road, then the Wheels move up and down - perpendicular to the road surface.

The parts to a car suspension include: the frame, the Suspension System, the Steering System, & then the Tires & Wheels . The Frame is the structural & load - carrying component that supports the car’s Rebuilt Auto Engine & the car’s entire body. The Suspension System is what supports the weight. It also absorbs and dampens shock while at the same time, helps maintain the contact that the tires have with the road. When it comes to the Steering System, this is the mechanism that allows the driver to guide and direct the vehicle .. if you didn’t already know that. The Tires and Wheels that are installed are the components that make vehicle motion possible by way of grip and/or friction with the road.

Are you still with me? Good.

The three fundamental components of any suspension system include the Springs, Dampers, and the Anti - Sway Bars.

The Coil Springs are there to compress and also expand to absorb the motion of the Wheels . The most common type of spring is a heavy - duty torsion bar that’s coiled around the axis. The leaf springs are a type of spring that has a number of layers of metal bound together in order to act as a single unit. The torsion bar type of spring uses the twisting properties of a steel bar in order to provide coil-spring-like performance. Finally, air springs are composed of a cylindrical chamber of air positioned between the wheel and the car's body.

Unless there’s a present Dampening Structure, a car spring will extend and then release the energy it absorbs from a bump at an uncontrolled rate. The spring will then continue to bounce at its regular frequency until all of the energy originally put into it is all used up. If there’s a suspension system that’s built on springs alone .. then just know that you’re in for a pretty bumpy ride - not to mention that the car will be uncontrollable.

The front Suspensions are dependent and have a rigid front axle that connects to the front wheels. In independent front suspensions, the wheels are allowed to move independently. If both of the front and back suspensions are independent, then all of the wheels are then mounted and also sprung individually. This results in "four-wheel independent suspension.” Any suspension that’s installed in the front of the vehicle can also be installed in the rear.

I guess you can say that there are some cases where suspension is hard to understand and then there’s other cases where suspension is the easiest thing to explain. Usually, I think it just revolves around one thing: keeping your drive as less bumpy as it can be and keeping the people in your car happy because it’s not so bumpy!
