Modern cars, thanks to the achievementsscience in the automotive industry, became the embodiment of perfection. Even inexpensive, budget cars can boast enviable characteristics, which five years ago were shown by the best sports cars or sedans of the executive class.
Over time, the car devicechanged its technical characteristics, behavior on the road, as well as the atmosphere in the interior itself. Previously, cars competed in power, speed, now the debate has shifted to environmental friendliness, economy, comfort smooth ride. Therefore, the design decisions had to be changed, and the suspension device changed, since it was designed to be responsible for this indicator.
If the suspension is too firmsettings, then it will behave well on a winding road, since the banks are at the same time minimal. Not without reason, racing and track cars have a very rigid suspension. But for road versions it is not applicable, especially for our roads. First of all, it is accompanied by a low ground clearance, which is simply unacceptable in our road conditions. In addition, it is also necessary to "swallow" irregularities, which are enough.
The front suspension used to have separate springsand shock absorbers, now they are combined into racks, it's called McPherson. It has fairly stable characteristics, easy to install and dismantle. In addition, the manufacturer himself can choose the optimal ratio of the spring and shock absorber, depending on the purpose of the rack.
The rear suspension can be different.This can be a transverse beam, on which leaf springs are fixed. They are sheets of metal, which have a rounded shape. Under pressure, they unbend, after which they take their form. The rear suspension of this type is used on the leading axles, usually large-class sedans, as well as pick-up trucks and trucks.
There is a rear suspension with springs.Here they are installed in glasses instead of springs. Springs have the usual screw configuration. Shock absorbers are mounted separately. Such a suspension has become widespread on the middle class sedans for everyday use. Again, it is applied with a leading moto or beam. Its name is semi-independent.
And finally, the last type is independent.rear suspension. This means that the wheels of the rear axle are not attached and can move independently of each other. It is quite convenient, but difficult to install, has a low carrying capacity. In addition, it uses only springs, which makes it softer. As a rule, it serves for small hatchbacks.
The rear suspension device directly affectssmooth running car. Here, its action will be noticed by more passengers of the second row, because it is they who sit just above it. In addition, do not forget that the performance of the suspension depends not only on its design, but also on the state, so do not demand high results from it when worn rubber seals or leaking shock absorbers.
