Although with the domestic cars in recent years, it has gone faster and faster, but every time a new car is listed, do you pay attention? Basically, the focus is on the engine. For example, the thermal efficiency of the engine reaches 43%, or even close to 45%, more than so-and-so, anyway, PK a bunch of international big guys, and then will mention the gearbox by the way.
But when lifting the gearbox, basically a lot of mention is that it is ZF, or Aisin, or whose family to cooperate with, and whose technology is used. But the chassis is very rare, in addition to the fact that the chassis has advantages, please is the Lotus team tuning, or their own chassis can also be, basically do not mention, why is this?
In fact, our domestic car, the chassis as a very weak project, can not mention as much as possible, because the most difficult and most laborious and unflattering, is the chassis this piece. If you follow these three orders, independent research and development to overcome, are the engine, transmission, chassis, so everyone first do the engine.
At present, the engine of the domestic car, the economic fuel consumption of the entire engine, and the durability of the engine, can basically be comparable to the engine of the international first-line manufacturers, and in some single-line technologies, it may even exceed some of the data of the international manufacturers, so this piece of data is more eye-catching, and it must be said.
And in addition to being able to take it, when using the car, for their own perception, it is also obvious, the most direct is that the fuel consumption is not high, the power is not strong, so this piece, naturally, has become an aspect of everyone's swarm and active publicity.
Secondly, the gearbox, for our ordinary people's car perception, but it is not so obvious, it is not frustrated in the end? Is it smooth or uneven? If the car itself is not very good, and even occasionally uneven, or when the gear shift, it is not so fast, may not be felt by everyone, so what everyone considers is that the gearbox is stable and unstable? Is the durability good?
Grasping this point, at present, the domestic car publicity is to cooperate with ZF, or directly buy aisin's gearbox, use the gearbox of the international manufacturer, its stability is certainly beyond doubt, everyone will feel that it must be very good when they hear it.
So to the chassis project, for us ordinary people, the perception of using it is even worse now, as for the chassis adjustment is softer? Or is it a little harder? Is the roll serious or not? Is the maneuverability good? In addition to those who really like cars, or friends who drive more and feel better at driving, many friends are actually very wooden.
Just like we listen to music, for example, many friends listen to music, it may be wooden ears, 10 yuan speakers, and 10,000 yuan speakers, can hear the difference, but 10,000 yuan speakers, and 500,000 high-end speakers, can not hear the difference. In fact, the car is the same, as long as you sit up and don't faint, sit up and crunch.
So in the chassis of this piece, for our follow-up, the perception of using the car is not so obvious, the manufacturer will not be, strive not to please to publicize, and even how to develop, coupled with the development difficulty of its own chassis is relatively large, and the cost is high. But before Brother Meow, he visited the Wuling chassis workshop, and Wuling is not a relatively expensive car, that is, tens of thousands, or 100,000 ranges, ordinary entry-level cars.
Brother Meow learned from communicating with their chassis engineers that Wuling had prepared more than a dozen tires, all of which were spring parts, one by one, one by one. Therefore, it can also be seen that this difficulty, in fact, the difficulty is that its cycle is long, its investment is large, and after it is finished, the balance point is not stepped on, but it is laborious and undesirable.
Finally, I spent a lot of effort to adjust, on the road a test found that the roll of the car is very serious, then hit back to the original shape, it is better to spend some money directly, to the mature team abroad, directly reverse the study of a set, or directly buy other people's data back, re-tinkering, both time-saving and labor-saving, and basically enough. That's why at present, many of our domestic cars only advertise key engines, and the gearbox is basically no longer mentioned.
Although with the development of new energy vehicles and trams, including the development of hybrids, the engine may still exist, but the key link in the middle is that the gearbox is canceled, directly over the gearbox ring, which is called curve overtaking. But the chassis cannot be avoided, because after all, no matter what kind of car, no matter what new energy, whether it is hybrid, the entire structure of the chassis is still in. Therefore, with the development of the chassis, I believe that our domestic cars will also enter the chassis research area.
Especially at present, the new energy is doing better, when Brother Meow visited BYD's factory some time ago, he found that BYD was in the engine, in fact, the technology is relatively OK, and then especially in the battery, and the technology of the hybrid piece, it has indeed been recognized by everyone, and it has achieved corner overtaking, so he is now also working hard to do the chassis, because no matter which technology the new energy takes in the future, the chassis is impossible to eliminate in the end.
So with the further development, our domestic car, I believe that in the future in addition to the promotion of endurance, publicity of 100 kilometers of acceleration, in the promotion of the electronic configuration on the tall, there may be a part of the car, the beginning will gradually pay attention to the development of chassis parts, because beyond the engine, after crossing the gearbox, the remaining largest piece, in the field of traditional vehicles, is the chassis this piece, whether for traditional fuel vehicles, or for new energy vehicles, it is a hurdle that cannot be crossed. In the end, you have to face it.
Therefore, Brother Meow also hopes that domestic cars, while achieving curve overtaking, can pay more attention to the research and development of these chassis parts, and can adjust the chassis assembly that is suitable for domestic road conditions, more excellent, more durable, and better to use, I believe that with the strength of our several mainstream, domestic cars, this day should not be too far away.
