Why are China s big trucks flat headed?

Why are the big trucks in the United States long-headed, while China's flat-headed? After reading it, understand the gap.

Various types of cars have their own advantages and disadvantages. For example, flat-top trucks, especially those with long bodies, are much more flexible than pointy trucks and have excellent handling performance, but in the event of a traffic accident, its safety factor is greatly inferior to that of pointy cars. I am shocked by the traffic accidents that occur on the road.

Whether it's a pointy car. It's still a flat-top car, and caution is the only magic weapon you can use to protect yourself. It can be said that if you drink 2 catties of two pots and then drive on the road, you will be given a tank, and you will not end well.

It's better to focus on improving your concentration and experience.

Indeed, there are few manufacturers in China that produce long-headed trucks, and the common long-head heavy truck is Dongfeng Liuzhou.

The Dragon Card series. This is due to several reasons:

1. China's relevant national standards such as the latest GB1589 have requirements for the length of the truck, in this case, too long the front will inevitably affect the length of the rear cargo compartment. In terms of cargo capacity, a flat-top car of the same length has a higher utilization rate. For truck drivers, it is of course excellent to be able to free up a few cubic meters of cargo space with a slightly shorter front of the car.

2. The technology of domestic self-developed heavy trucks basically originates from Europe, such as Steyr.

Since the trucks in Europe are basically flat-top trucks, most of the domestic models are also flat-top trucks.

3. Compared with long-head trucks, flat-top trucks have the characteristics of small steering radius, good vision, light weight and better fuel economy, and are more suitable for China's traffic conditions.

So, why are most of the trucks in the United States long-headed?

This is mainly due to two factors: the transportation policy in the United States and the advantages that long-head cars have. Before the 80s of the last century, the truck in the United States was also regulated on the length of the whole vehicle, and at this time, the truck market in the United States was also dominated by flat-top trucks. After that, in order to increase the carrying capacity of the truck and reduce the logistics cost, the U.S. regulations changed to restrict the trailer, that is, the part behind the front of the vehicle.

Due to the advantages of long-top trucks that better meet the driver's needs for driving comfort and driving safety, the trucks on the U.S. market are gradually changing from flat-top trucks to long-top trucks.

Because in China, there is a certain limit on the total length of the vehicle, and the total length of the vehicle here refers to the length of the cargo box + the front of the vehicle. Under such regulatory requirements, in the consideration of pulling more goods (the front of the car is short, the length of the cargo box increases), the long head truck with a larger head length has no advantage, and although the safety of the long head truck is slightly higher than that of the flat head truck, but in China, the interest is everything, safety? Are you cursing me for an accident when I get into a truck?

Therefore, gradually, the once popular long-head trucks gradually withdrew from the historical stage, and the domestic truck market became the world of flat-head trucks.

Most of the front of China's large trucks are flat, this is because: the non-load-bearing chassis must be shorter and more material-saving, and the square front does not need to invest too much in design and material costs. Therefore, most of the trucks in Europe and Japan and South Korea are flat-topped trucks, and the design of domestic trucks is influenced by European car culture, and the results can be imagined.

The main reason for this is that it is safer, because it allows for a better security.

The market choice under the constraints of the law, taking the tractor as an example, Europe and China limit the length of the whole vehicle, and the United States only limits the length of the semi-trailer, and the front of the vehicle is not limited. In fact, there are many trucks with long cabs in China, but the amount is very small, and individual users rarely purchase them. The long-head cab has a lot of space and the interior can be done very comfortably, making it very popular for long-distance driving.

Long-head trucks, mid-rear-wheel drive, European standards, user needs, safety differences.

Optimus Prime is the main element that makes Chinese cardholders realize the American truck, the ultra-long front end, the oversized driving of the American tractor front does look very powerful, and it seems to be safer. However, it seems that only American trucks in the world use the "front-rear-wheel drive and long-head design", and the Eurasian automobile market is dominated by flat-head trucks. The answer may be a little unexpected:

Capacity requirements. Rail transportation in the United States is not the main force of land transportation, and the core of land transportation is road transportation. Therefore, the demand for the carrying capacity and power of the vehicle is very high, referring to Cummins, Navistar, Calbit and other well-known OEMs, the diesel engine equipped for the truck has a huge displacement and huge volume. If the engine is stuffed under the cab with a mid-rear-wheel drive layout, the height of the front of the car will be very exaggerated, which will have high requirements for the height limit of the road and bridge, so only the OEM will succumb to the road design and use the long head design.

01User needs.

The United States calculates the length of the vehicle without counting the front of the vehicle, for example, the requirement of 17 meters is only the length requirement for flatbeds or containers. However, in Europe and Asia, the total length of the car train is measured, and the same 17-meter requirement is to join the locomotive to the front of the car.

An inch long and an inch strong is the wisdom of the truck industry, the cargo box can pull a few more tons of goods by one meter more, there are many lengthened cars in the stage of overloading and overrun management is not strict, and there are really some long-headed trucks running on the road at this stage.

However, with the implementation of electronic (intelligent) governance, as well as serious accidents caused by the destruction of roads and bridges by overloaded vehicles, such vehicles are rare in the real transportation field. So if you want to maximize the transportation space, you can only choose a flat-top car, and the space saved is very valuable to pull the "dumping", which is the reason why domestic heavy trucks are mainly flat-head cars, and to put it bluntly, it is a helpless choice for cardholders.

02 Security level.

Analysis: Assuming that a flat-top car collides with a long-head car, there should be no controversy as to which car is more seriously damaged! Flat-top cars don't have a little bit of a crash buffer, and if you crash a small or micro car can still rely on the chassis and metal bumpers to withstand the impact, but if you collide with a truck or bus with a huge curb weight, the result can be imagined.

Summary: Flat-top vans are not an ideal option for safety, just as flat-top vans are the least safe in the passenger car field. However, from the perspective of transportation capacity and the perspective of car companies controlling manufacturing costs, flat-top cars are the most suitable models for the current rules.

And although the long-headed car is noisy first, it is destined to be unadaptable, because even if the safety factor of this vehicle is higher, the fuel consumption will be much higher, and the user will not accept it subjectively in the face of the increase in operating costs.

There are some differences between long-head trucks and flat-head trucks, but our country is basically flat-head trucks, and it is rare to see long-head trucks, because of some regulations, this domestic regulation requires the truck to not exceed how many meters at the longest, in order to leave more space for the back boxThe cab in front of it should be appropriately reduced, so many of them are flat-headed in China now. <>

Long-headed trucks are widely used in American countries, because the United States has made certain modifications to this, long-headed trucks are more common, long-head trucks have many advantages, such as better safety, because long-distance trucks if they hit something on the side of the road or collide with other cars, the cab is not in the front of the front of the bumper to the cab is about one or two meters away,This distance can leave a large buffer space, which can have a better guarantee effect on the safety of the personnel in the cab. <>

It is more convenient for long-distance trucks to get up and down, but it also has disadvantages, such as the problem of vision, because the front of the flat-head truck is flush with the bumper, and there is almost no big nose in front, which naturally has nothing to do except for the blind spot caused by some heights, and the blind spot is very convenient to see clearly, but the long-distance truck because it has a very long nose, this nose is the engine, plus his seat compartment is not so high,So it caused some blind spots, and this long-headed truck was not as perfect as he imagined. <>

Because we require that the length of the truck in China cannot exceed a certain standard manufacturing, the manufacturers of these trucks in order to make the box behind the pulling goods have a larger space area, so the long nose of the cab has been transformed to a certain extent, and it is not considered to be our transformation, because the technology of our trucks is learned from European countries, and they are basically this kind of trucksThis kind of truck is better in vision, and then the space utilization efficiency is stronger, and the main body has less impact on the cab when turning.

Because flat-top trucks are very affordable and cost-effective. However, foreign countries pay special attention to safety and comfort, so they tend to focus on long heads.

Because the aesthetics of Chinese and foreigners are different, they are generally dominated by flat-top trucks in China.

Because each country has a different culture, a different living environment, and different things and styles of things you like, the shape of the car you like is naturally different.

When it comes to foreign countries, they are all long-nosed trucks, but this is not the case. The situation in European countries is very similar to China. Most of the trucks on the road are flat-top trucks.

At the beginning of the 21st century, the long-head car series of major European manufacturers were discontinued one after another. In fact, long-head trucks are just the most popular in the United States. The United States is sparsely populated, especially on the highways of the Western West.

It is very common to run tens or hundreds of kilometers without encountering a car. Many roads are straight, so there is no need to think too much about the turning radius of this round. In addition, because there are few people, the eyesight is relatively poor, and the impact is not great.

However, the long truck is easy to maintain, the power compartment is in front, and the power compartment can be directly repaired up and down, left and right.

<> after reading your answers, it's interesting. Most people don't understand why. Many physical and chemical analyses do not explain why.

The answer is better. In fact, in the case of vans, the U.S. began to calculate the length from the last wheel of the front end, so the front end is long, safe, easy to maintain, and bright without compromising load capacity. In China, the length is counted from the front, and the trucks are still mainly loaded with wax cargo.

Therefore, with the same wheelbase, it is necessary to increase the cargo space as much as possible, and the cost of a long-head car is higher than that of a flat-head car, and of course, not all trucks can meet a certain demand.

In fact, the first domestic trucks were built with the front end of the engine. Dump trucks are less difficult to produce and less costly. From the first CA10 truck after the founding of the People's Republic of China to the Dongfeng and 142, they were all built in cutting-edge shapes.

After the 80s of the 20th century, Japanese flat-top trucks entered the Chinese market. The charm of flat-top trucks is that they have a good visibility, short body, long containers, large steering angles, and small turning radius, so flat-top trucks are highly regarded. Subsequently, Jiefang also launched its own series of flatbed trucks:

ca151。Since then, the Jiefang series has fully entered the tablet era, and other brands have followed suit. Sharp trucks disappeared from the market overnight!

If you search for this question on the internet, most of the answers you get are that the United States has a high level of forest cover. If the exhaust pipe is down, the hot gas will ignite the forest and cause a disaster, if the exhaust pipe is up, this problem can be avoided; In addition, the exhaust pipe upwards allows the exhaust gases to be discharged directly into the air to avoid deposition on the ground; It is necessary to reduce noise and pollution.

This is a basic configuration of our country's shelter, and then the flat-headed Qilichang car is more in line with the aesthetics of the public, and it will be particularly smooth when turning, and then the road surface of our country is also particularly straight.

This is the problem of car design car travel, so that there is more room for expansion, so there will be such a design as a closed key stool, many foreign countries are also like this, only some countries are others.

The main problem is the design, and the flat-headed ones can have more storage space, so there will be such a design, and most of the foreign ones are also flat-headed.

It's because it's safer to keep an eye on the flat head, and you can see the road better. Foreigners think that the front of his car is more sleepy and stronger, and it is more resistant to collisions, and everyone thinks differently.

The front of American trucks is long, while the front of domestic trucks is flat. Before the 80s of the 20th century, flat-top trucks were as popular in the United States as they were in China. China has many mountains and complex road conditions.

Flat-top trucks have short bodies and nimble turns. Obviously, they are more suitable for use in China. The idea is similar in China, and so is in Europe and Japan.

The roads in Europe are narrow, and many mountainous areas in Japan require flexible trucks, and there are many flat-headed trucks. Cars have become the most common scenery on the road.

In addition to the increasing use of cars, there has also been a lot increase in trucks. But with the development of the Internet, many car enthusiasts have found that there is a big difference between Chinese trucks and American trucks. I believe that attentive friends have discovered that our country is full of flatbed trucks, while American trucks are all long-nosed.

For this state, many truck drivers who understand the situation say: this is the gap. This difference is mainly due to the requirements for wagons in our country.

China has requirements for car design.

One of them is the tuning of the whole vehicle body. In the United States, there are clear regulations on the length of containers that can only be pulled by trucks. In addition, American truckers like some styling that can show strength, such as the design of long-nosed trucks, which is just right for their vision.

The United States is a sparsely populated country. The roads are wide and flat, and there is less traffic, so driving can be a pleasant experience. The United States is basically simple and does not care about flexibility.

About half of the land in the United States is plain, and the roads are relatively straight. It's not necessarily how to turn. Of course, we don't get hung up on the question of whether to be flexible or not.

From the perspective of safety, the trucks in the United States are very long, which will cause a big blind spot to a certain extent! For flat-head trucks, compared with large-head trucks, the field of vision is wider, there are fewer blind spots, and the safety factor is higher! Because of the terrain and national conditions, it is also for safety.

In fact, the main reason why trucks in China are flat is because of the high traffic pressure. The front of the truck is designed to be flat, which is not only convenient for observing the road conditions when driving on the road, but also meets the requirements of rational use of space to a certain extent. Our country's position in terms of transportation is very clear, compared to our trucks.

So in order to improve the efficiency of transportation, reduce the space occupied by the locomotive. In this way, the trucks can be used rationally in space and the efficiency of cargo transportation can be improved. One of the reasons why the United States has designed trucks to grow into noses is that the uneven distribution of the population makes them not stressful to traffic, so there are not many restrictions on truck design.

Therefore, they will give full play to their favorite preferences and show their personality when they come.
