Coquettish Rebirth

"People in the United States will buy this kind of car, and they will not be considered as top rich people. Generally speaking, they are relatively high-end middle class. It is estimated that they are mainly doctors and lawyers. These people have money, but the distance between It’s even worse to buy large yachts and the like. These people go on overseas vacations with their families every year, and then there are various small villas for wild vacations in the United States. Some people may go hunting and fishing in Alaska, and some people may go Go to a jungle hut in the Rocky Mountains for a week, go boating and fishing every day. It is possible to drive to these places, and some people will hang their own small yachts on the back of the car. So if you go on a domestic vacation, I guess it might take some bad terrain. Four-wheel drive is still needed!" Jia Hongjian said after thinking about it.

Jia Hongjian knows that in such a time and space, the Chinese market’s preference for SUVs has not yet been discovered, and the Chinese people’s hobby of big cars has not yet been discovered, so the absolute majority of the world’s SUV market is still in the United States. Saying that the United States is the foundation of the suv market!For example, in a survey conducted in the United States in 97, the total number of suvs in the United States at that time was as high as 1380 million!Nearly 1400 million vehicles!At that time, there were only more than 2 million people in the United States!This means that less than one out of 20 people will buy an SUV!At that time, the sales of suvs and pickups in the United States accounted for 50% of new car sales!Why are there so many SUVs sold in the United States?The main reason is that it is the same as our China Wuling Light and other small vans that sell as much as they can carry people and goods!

Many cities in China have stipulated a series of complicated regulations that trucks are not allowed to enter the city, which has caused many small businesses to have trouble transporting goods, so in the end they started to use small vans such as Wuling Light to transport goods. .Among other things, this kind of minivan is really no worse than a pickup truck when transporting goods, and it can still run a ton of goods at every turn!And in case something happens at home, the car will drive out to pick up a few people or something.That is also very convenient!It can be said that apart from getting troubled by the traffic police, the others are really easy to use!In the United States, although there is no rule that trucks such as pickups cannot enter the city, for many Americans, suvs also take into account the functions of pickups.If you buy a lot, you need to bring something with you.On the one hand, you can open the back door of the car, put goods inside, and even the rear seats can be folded down, so you can really put more things!

Moreover, a model like suv has a certain off-road capability. Although the fuel consumption is higher than that of a car, the United States relies on their troops stationed in the Middle East and oil prices in dollars. The United States can get cheap gasoline!Americans are not afraid of too much fuel consumption!But in 2005, when the world oil price suddenly rose to 70 US dollars.Even Americans, who have always been rich and powerful in the past, suddenly find that they can't afford oil!As for the various suvs of oil tigers, the sales of course will drop all of a sudden.Therefore, the four-wheel drive function is still required, but it cannot be a full-time four-wheel drive, and it must still be adjustable.In this way, consumers can switch to two-wheel drive when driving in the city, and switch to four-wheel drive in the wild or when the road conditions are not good.

In the past, gasoline suvs could be switched in this way.The main reason is to save fuel, although we don't need to consider the problem of fuel money for such an electric suv.But you have to take into account the power issue!Although our suv uses 1 18650 batteries to form a battery pack, after using twice as many motors, the power consumption will definitely increase.Although there are a total of four motors, the acceleration data of hitting 30 kilometers will definitely look good, and the unit power will also look good, but the problem is that the power consumption will increase even if it is not doubled.Even a 300% increase would be unbearable!Originally, the range of a single battery pack in the suv design is about 350-30 kilometers. If this is reduced by another 300%, the battery life will drop directly to [-] kilometers. At that time, the battery will have to be replaced twice in the middle for a distance of [-] kilometers. , which is easy to feel troublesome.

at the same time.This car does not mean that the power consumption has increased and the battery can be added, so it can easily become a vicious circle like the German tanks in World War II.Many military fans think that German tanks were invincible in bicycle ability during World War II. This is just from the perspective of military fans. It really makes them consider the value of tanks as weapons from the perspective of the country. Then they will definitely wish for it Tear up the German military designers alive!why?Because the German blitzkrieg was fought well at the beginning, and when the results were brilliant, it did not use the famous Tiger and Leopard tanks, but the No. [-] and No. [-] tanks that were worse than the French tanks!

Then the No. 34 tank was barely enough, but when the Soviet t-34 tank appeared, the German army on the European Eastern Front in World War II directly faced the t-34 crisis!At that time, the guns of German tanks could not penetrate the Soviet t-34, but the t-34 could penetrate them again. At the same time, the t-400 also adhered to the Soviet strategy of maneuvering in depth. The failure rate of a bicycle running 34 kilometers was not very high. The Germans really can't stand it!Then the Germans wanted to develop a tank that could restrain the Soviet tanks. Although the appearance of the resulting tank was borrowed from the T-[-], it was a bit out of shape in other aspects. Tanks are basically built because the engines are placed behind the car body. Therefore, the rear tilted wheels are generally used as driving wheels. In fact, the five or six pairs of six or seven pairs of wheels on the ground of the tank have no power, and only the front and rear of the tank body test the four tilted wheels. The raised wheels are equivalent to the four wheels of a car.For example, the Soviet and American tanks put the drive wheels at the back, which means they are rear-drive like a car, and then the wheels on the ground have no power, but are driven by the tracks when the drive wheels drive them.But the Germans don't know what's going on, they insist on making it a pioneer!

Their engine is at the back of the car body. If you want front drive, it is the same as a car with the engine in the front but rear drive. There must be a drive shaft at the bottom of the car!Cars can put the drive shaft outside the bottom of the car, but tanks can't, otherwise the drive shaft will be damaged when the infantry throws a grenade, and the car may not be able to move!So the transmission shaft must be placed in the lower part of the car body, so the car will become taller?It may not be a problem for ordinary cars to be taller, but it will be fatal if the height of a steel tank is higher - tanks have various armors!The height is a little bit higher, does this armor have to be a little higher on the basis of maintaining the previous thickness?One side is higher and the other is higher, and the final result is that the weight can be several tons heavier!

This is a few tons more weight, does the engine power seem insufficient?So is it necessary to change to a bigger engine?After changing to a larger engine, is the engine weight also increased?Did the weight increase again?This leads to the fact that the mobility is enhanced, but not much!And at such a time, the car may have been originally designed to be 30 tons, but in the end it has become 40 tons!After this, the potential to upgrade to a larger turret for a more powerful gun is limited!Moreover, after the weight of the vehicle increases, the pressure on the suspension travel system also increases, and these things are more likely to break!And the most critical thing is that the man-hours for manufacturing have also increased!

For example, after the t-34 is extremely simplified, the construction hours are 2-3 man-hours per car, which means that a worker can build a t-2 after 3-34 hours of work, and like the German Panther What about tanks?It is said that it is designed to target the T-34 tank, but the construction man-hours are as high as 15 man-hours!That is to say, the effort to build a Panther can build almost 5 t-34s!Even so, the Panther is still the shortest construction time among German late-stage tanks!The Tiger is 25 man-hours, and the King Tiger tank is 30 man-hours!It is so troublesome to manufacture, how can it compete with the t-34, which is simple and can be mass-produced?

Of course, we definitely don't have as much trouble making cars as tanks, and adding two motors won't add too much man-hours.But in the same way, if there are too many motors, batteries need to be added, and the weight of the battery pack will be heavier. At the same time, due to the increase in volume, the battery box for the battery must be redesigned, and the chassis armor must also be redesigned. The final result is that the car still has A certain amount of weight gain... Is it really worth it to make so many improvements?Not all the users who can buy our suv are contractors, and they don’t have to go to all kinds of wild wasteland all day long, so why do they do this?

Therefore, under Jia Hongjian's decision, this SUV is basically determined to be equipped with four motors, but it must have the function of switching between two-wheel drive and four-wheel drive.After Mr. Guo Konghui understood that suvs also need to run points, he quickly overturned the previously designed suv shape plan, and planned to redesign the shape and send it to the wind tunnel for blowing, pursuing a relatively small drag coefficient. Appearance, in this way, at least it can slightly enhance the scores of SUV running points, can't it?The old man also understands now that a product like a car, especially a market-oriented product, often needs to have a bright spot in order to attract consumers.It is better to have bright spots and short boards than to be mediocre. At least in the eyes of consumers, mediocre means no bright spots!

And when the old man redesigned the shape and was about to go to the blowing hole, the representative of Huaxia Hi-Tech also went to Dawan, planning to talk to the five brothers and sisters of the Zhang family about the acquisition of shares in Tomita Electric.This means that after going there, I got in touch with the five brothers and sisters of the Zhang family, and found that the other party was similar to Mr. Jia's previous judgment, and they didn't want to sell the controlling stake at all!Although it is said that capital injection is welcome to acquire shares, it is only willing to sell 30% of the shares!
