Suspension and shock absorber operation
Content
What role do your shocks and suspensions play?
Shock absorbers and suspensions, designed to absorb shock, greatly contribute to road stability and driving comfort. So let's take a look at the main features of this device.
The two components (suspension and shock absorber) are often confused because they are very often (front axle) integrated into each other. There is a yellow spring (suspension) and a metal shock absorber (everything else).
Difference between suspension and shock absorber
If we often use one and the other in a rather anarchic manner (I am one of those people ...), we must, however, distinguish between damper and what the podcast ...
At the rear, the shock absorber and suspension are usually mounted side by side rather than inside each other. So it's perfect to illustrate the difference between the two.
1 : This is about podcast, its role is suspend car in the air. Thus, this is the only thing that allows your car to be on top and not fall on the shock absorber stops. A spring is not the only way to hang a car in the air.
2 : His'damper, his role is to moderate and improve (thispillows) On
suspension travel
to avoid bouncing (because that's what the spring wants to do at the base! In relaxation, it recovers a lot of energy). Thus, it makes the suspension more effective at keeping the road, as it significantly improves how your chassis will deal with damaged roads and tight corners ... It helps to make the damping more or less steep (depending on its characteristics). If the movement is very permissible (ascent and descent without much resistance), then the response to shocks will be smoother. Conversely, shocks that are less tolerable in terms of movement will cause dry reactions, even if the springs are quite flexible.
To summarize, flexible springs will cause body movement in the support, even if there are crazy bumps (the car will just take longer to hit the suspension). Stiffer springs (usually shorter versions) tend to restrict travel and result in dry lift, even if you have soft calibrated shocks.
Heavy impacts will prevent the vehicle from hitting the suspension too quickly when cornering or driving over bumps. Relaxing the setting will greatly increase comfort, but sporty driving will be difficult due to the many body movements and excessive pitching. Know that engineers are racking their brains to find the perfect symbiosis between the two so that they work at their best. This is all the more difficult when the car is high on its feet (SUV).
Note that the spring can be replaced with airbags in the case of air suspension, leaf springs (flat metal rods, rather for trucks carrying heavy loads / old cars) or torsion bar, but a shock absorber must always be present. ... Controlled suspensions make the shock (2) more or less flexible in its movement by playing with the small internal valves (other methods exist). The latter affect the fluid flow that unites it: the easier the fluid flows from top to bottom during reciprocation, the more flexible the damping will be.

Types of shock absorbers
There are several types of shock absorbers, twin-tube and single-tube shock absorbers. Monotubes are better in terms of capacity (used for more sporty cars), but more expensive (they heat up less and retain their capacity even under hard impact).
There are also so-called gas shock absorbers, which contain a supply of compressed gas instead of air in conventional versions. This improves damping response and limits heat (as in tires, nitrogen prevents overheating and pressure build-up) during sporty driving.

Types of suspensions
There are also several suspension techniques. Therefore, the most common is the coil spring, which is therefore a simple metal spring. It will be more or less a log, if desired, adjust the height of the body more or less high. There are also leaf springs, which are metal rods (sheets) flattened and stacked on top of each other.
Let's not forget about the air suspension, which this time consists of the suspension of the car thanks to the air trapped in the chambers (socks), which we see on high-end cars.

Bsr Sir, I have a Fiat Qubo automatic box bought new in July 2015. On the odometer today 115000 km. I already changed the shock absorber plates 3 years ago (at around 60000 3 km). A month ago, she began to make the same noise as 10 years ago, when I turned the steering wheel, after a week this noise stopped. TO?? now it comes back very slightly, but it seems to me that my car no longer holds the road behind. I only got an appointment with my mechanic this Friday 200 but I couldn't hear myself as he was on vacation. Is it dangerous to use my car this far? I absolutely need it for work from tomorrow from Monday to Thursday inclusive, which will make me drive about XNUMX km this week. Thank you in advance for your reply please. My job is to lead the children! If there are risks, what are they? What do you recommend ? TO?? I will be reading you soon. Best wishes. Dominica
