About half a month ago, Brother Hu wrote an article specifically analyzing the "difference between the texture of the Ashkenazi and Japanese chassis tuning.". It discusses the amount of damping of the suspension system movement and the strength coefficient (K coefficient) of the elastic part (spring). Originally, it was just a post explaining the knowledge of the chassis, but I didn't expect that the reading volume was very high.
In the message area, Brother Tiger read the messages of several car friends, and the things they said were roughly the same: they expressed dissatisfaction with Japanese cars, and the dissatisfaction was mainly concentrated, they thought that Japanese cars were "thin and stuffed, and they would break when they touched." It's not as thick and sturdy as a German car."
Not to mention, it is 2020, and many riders still adhere to this concept. In fact, many media in the past have painstakingly explained N more, such as "the real force is the skeleton, not sheet metal (skin)" and other such popular science, the majority of car friends should have been familiar with the heart. So I didn't want to repeat these clichés today.
Japanese car skin thin filling? Ashkenazi thick?
Brother Tiger moves out of the private house to prove it!
Today I want to start from a simplest truth, to analyze whether the Japanese car is thin and stuffed, it will be broken when touched, and whether the German car is as "thick material" as imagined. The method I used is very simple: compare at the same level! The level mentioned here is what we often call A00, A0, A, B, C, D and other different size levels.
In this issue, we only say German and Japanese Ha, as for the Korean system for many years to imitate the Japanese system, and today's American cars, in fact, everyone understands that many of the General Motors are German Opel to change the standard, and Ford's hot cars are the products of the German center research and development... Therefore, there is no need to say it separately in the Korean and American systems.
Since it is a comparison of the same level, it must at least be A level to A level; B level to B level. Of course, a more accurate comparison will certainly require the wheelbase to be similar, the wheelbase to be almost the same, the length, width and height of the vehicle to be similar, the engine displacement is also close, and the price range is basically consistent. That's a convincing comparison, right?
Same level "body density" comparison!
Result: Ashkenazi and Japanese!
For example, we look at the largest and most common models on the market at present, Volkswagen Langyi, Sagittarius, Passat, Toyota Corolla, Raling, Camry... Or add Nissan Xuanyi, Tianlai... According to the "same class" principle, readers can search for one of their own indicators - empty car weight.
You will be surprised to find that the original Ashkenazi, Japanese, Korean... "the weight" of the "same level" models is roughly the same, basically at the same level. So can the rumor that "the Japanese system is thin and stuffed, and it will break when touched" still hold true? It's like: a few young people, competing against each other to see "who is strong, who is fat".
These young people, tall, fat and thin, seem to be similar at first glance, and their body shape seems to be quite close. What to do? So someone proposed: get on the scales! Under the same volume, who weighs heavily means who is "stronger", and who is lighter represents who is "fat". As a result, they weighed the scales and found that everyone's weight was "head to head, foot to foot". So who do you say is strong and who is fat?
After the 21st century, "lose weight" for fuel consumption
"Muscle gain" for safety is the main theme
In fact, after entering the 21st century, the "new era" Ofte and Japanese... "body density" is not much different, or it can be said that they are all at the same level. You also say to me, "Who is thick and who is thin-skinned"? As for why I asked me, why are the Ashkenazi and Japanese systems getting closer and closer now?
In fact, it is nothing more than two motives: one is that after entering the 21st century, the environmental protection indicators of vehicles have an additional "fuel consumption index". That is to say, EU countries are also paying more and more attention to and emphasizing the control of vehicle fuel consumption. So the weight of the body had to be lowered. Today's German cars, in fact, simply speaking of sheet metal (skin) thickness, are usually between 0.8 and 1.25 mm (the same is true for the Japanese series).
Second, today's automotive safety crash test standards are becoming more and more stringent, and Japanese cars are "globally marketed", so they have to pass the test (otherwise European countries will not let them sell). Therefore, the current Japanese car has to increase the input of materials. Therefore, the "weight" is also getting heavier. The result of this is that asthe ashkenazi and the Japanese are becoming more and more similar to each other.
Ashkenazi and Japanese sheet metal are similar in thickness
The so-called sense of heaviness is nothing more than the result of tuning
Of course, if you can't measure the thickness of sheet metal, then the next time you do maintenance, you may wish to observe the chassis of your car, compare other vehicles in the store that are doing maintenance at the same time (if you just happen to be able to "compare the same level of German and Japanese"), see the thickness of the hanging swing arm, the thickness of the lateral stabilizer bar, the appearance size of the spring, shock absorber and other components... Actually, I tell you, it's all the same!
So back to the popular science text half a month ago, the Ashkenazi and Japanese systems give people the feeling of a thick and a light, in essence, it is nothing more than the difference caused by chassis tuning. The K coefficient of the spring is naturally stable with a high point + a shock absorber with a larger damping; the same is true for the reverse. As for the difference between the thickness and thinness of sheet metal "tapping feel", hehe, and then the thin sheet metal supports a reinforcing rib, you can't knock it out! In a word: shrimp have shrimp roads, crabs have crab roads. They are all automobile powers, and no one is worse than anyone else.
