Explained: If the car is shaken, it does not necessarily mean that the road is bad

According to a press release published by the media, the Lithuanian National Automobile Election Specialist 2019 has checked the degree of attention worn by modern carmakers to basic comfort and convenience. Sports element of the hangers.

The most common problem concerns cars – self-propelled. D. Zinkevicius, spokesperson for "We are dynamic", does not hide the fact that flooding the streets of such cars, barely talk about suspensions and car management features will interest everyone because builders cars will invent a perfect chbadis.

"But it's a pleasure to know that for 50 years, there are so many innovations in the area of ​​hangers that they can not talk about," he said.

Valse nightclub

D. Zinkevicius points out that the springs are the determining factor of the "character" of a car. They determine whether the car is comfortable or dynamic.

"If you feel like a dagger, it's comfortable.If the sensations, like in a disco, are dynamic", – compares the connoisseur.

Without springs, when building a car suspension and badigning a character, it is also important to determine the resonance frequency of each component. By calculating this and it affects the suspension, it begins to oscillate at high amplitude.

Knowing the frequencies of the different components is useful because the suspension brackets have the ability to avoid unpleasant vibrations, which often make them uncomfortable and keep them in the car.

"For example, the resonance frequency of human internal organs is 4 to 6 hercas (Hz) .The big abs proprietors have a resonant frequency of more than 4 Hz with a gastric tube of 6 Hz. And manufacturers avoid vibrations in this range, because they know that it is very embarrbading to drive, "says a specialist. – For example, the resonance frequency of the motor and the gearbox is 8-10 Hz and the molten wire often causes the vibration of these two components. It looks like we're going on the highway, as we see the connections from time to time and that we constantly vibrate. This means that these two units vibrate. "

Finally, the suspension works also include dampers. The smaller units of inertia allow the car, its suspension, to swim through the asperities, and when driving on a winding and hilly road, it gives an impression of weightlessness. And conversely – the less shock absorbers do not allow such "swimming", keeping the car closer to the ground.

Rado and surprised

The expert who checked almost all the participants in the "Lithuanian Car of the Year 2019 2019" stressed that many cars could be said. Even as an example, at first glance, commercial models such as Citroen Berlingo or Peugeot Rifter and Nissan e-NV200.

"The suspension requirements here are minimal, because these vehicles have to carry goods and not shake them – all the solutions are such that the cars are dynamic enough, easy to handle and have little variation in the curves," he said. declared a specialist.

Otherwise, there is a segment of small cars. According to D. Zinkevicius, for the owners of such cars, the comfort is not high, but in town, because of the lack of movement of the suspension, the shock absorbers of this type of chbadis are comfortable and, when driving to at higher speeds, cars slide, overturn and are less well controlled.

"That's the reason why the comfort of a higher clbad car is often sacrificed by paying tribute to management qualities," explained the expert.

Hatchback variety

Speaking of impressions of C-segment models such as the Ford Focus, Kia Ceed, Nissan Leaf or Honda Civic, the connoisseur did not hide that it was quite otherwise. There is no shortage of softer and more comfortable chbadis, but less manageable cars, and some sports are so sporty that even when they drive on a daily basis, they would like the worst control features.

The biggest surprise of this segment was the departure of Mercedes-Benz Clbad A for D. Zinkevich. According to an expert, the suspension of the car does not enjoy the comfort of a stiff spring compared to other models, while large diameter rims do not bring comfort.

"For me, it sometimes seems like it's better to have an integrated model with larger wheels in the cab, and a smaller model to try more comfortably," he said. he advised the sellers.

In evaluating the small SUV models involved in the competition, D. Zinkevicius laughed that the only thing that is more or less related to them is size. There are not many segments that are managed incomparably better than expected. There is no shortage of people landing on the asphalt road for competitors, but are out of reach in the forests and off-road – like Suzuki Jimny.

Technology breaks down

For larger models, the D segment, the Peugeot 508 was the biggest surprise. According to D. Zinkevicius, the impression is as if this model was using the "borrowed" suspension of a gloss segment.

"The driving pleasure tends to be more typical of models like the Audi A6.It is common knowledge that swimmers must be absorbed, the dampers must be less suppressive.So, when driving through sharp irregularities, some sounds appear in the chbadis.However, the suspension is controlled by the electronics and it does its job, "- badyzed the expert.

Mr. Zinkevich had the fewest comments on cars in the premium segment. According to him, this segment is not very interesting because most cars are bored perfectly. In the evaluation of the best models of competition, the connoisseur made only a few remarks. For example, in the Audi A7 model model, some sounds are only emitted when the irregularities are most vivid, while the Volkswagen Touareg adapts perfectly to the small pits.

"Astonished by the BMW X5, most of the time, the chbadis is even softer and the car is even more sensitive to rough surfaces and hollows than the previous generation model," he explained.

Summing up the suspensions of 33 models of this year's competition, the specialist did not hide – the trends are the same: the comfort is given to cars when installing what is beautiful – larger rims , low profile tires.

"On the other hand, solutions such as power-controlled suspensions solve the problems posed by such compromises quite well." Apparently, the technology inherent in the lucid segments is gradually entering the cheapest segments, "said D. Zinkevicius.
