Modern cars, thanks to the achievements of science in the automotive industry, have become the epitome of excellence. Even inexpensive, budget cars can boast of enviable characteristics, which five years ago were shown by the best sports cars or executive sedans.
Over time, the device of the car changed, its technical characteristics, behavior on the road, as well as the atmosphere in the interior, changed. Previously, cars competed in power, speed, but now the debate has switched to environmental friendliness, profitability, comfort and ride. Therefore, the design decisions had to be changed, and the suspension device changed with them, since it was she who was called to be responsible for this indicator.
If the suspension has too hard settings, then it will behave well on a winding road, since the rolls are minimal. No wonder racing and track cars have a very stiff suspension. But for road versions it is not applicable, especially for our roads. First of all, it is accompanied by low clearance, which is simply unacceptable in our road conditions. In addition, we must also “swallow” the bumps that are enough.
The front suspension used to have separate springs and shock absorbers, but now they are combined into struts, it was called MacPherson. It has a fairly stable characteristics, easy to install and disassemble. In addition, the manufacturer himself can choose the optimal ratio of spring and shock absorber, depending on the purpose of the rack.
The rear suspension may be different. It can be a cross beam on which leaf springs are fixed. They are sheets of metal that have a rounded shape. Under pressure, they unbend, after which they take their shape. This type of rear suspension is used on driving axles; as a rule, these are large-class sedans, as well as pickup trucks on a loading platform and trucks.
There is a rear suspension using springs. Here they are installed in glasses instead of springs. The springs have a conventional screw configuration. Shock absorbers are mounted separately. Such a suspension is widespread on middle-class sedans for everyday use. Again, it is used with a lead mot or beam. Its name is semi-independent.
And finally, the last type is an independent rear suspension. This means that the wheels of the rear axle are not fastened in any way and can move independently of each other. It is quite convenient, but difficult to install, has a low load capacity. In addition, she uses only springs, which makes her softer. As a rule, it serves for small hatchbacks.
The rear suspension device directly affects the smoothness of the car. Here, second-row passengers will notice its effect more, because it is they who are sitting just above it. In addition, do not forget that the performance of the suspension depends not only on its design, but also on the condition, so you should not demand high results from it with worn rubber seals or leaking shock absorbers.
