North American truck drivers immigrated to Japan.

Although American trucks have long heads, domestic trucks have flat heads. But in fact, before 1980s, flathead trucks were popular in the United States and China.

Chinese and American laws and regulations are different.

From 1980s to now, American laws and regulations only limited the length of cargo hold. Before 1980s, American federal highway laws and regulations always limited the total length of tractors and trailers. In order to load more goods, we had to make the cargo hold longer and the front of the car shorter, so flat-headed trucks were also popular in the United States at that time.

For example, 1984, Optimus Prime in Transformers animation is a flat head, right? Liu Xuewen's paper was published in Transportation. Vehicle) to share with you.

Is China far from the era of long trucks? -Recording a press conference in Navistar, USA. It was mentioned that in 1982, American law was changed to limit the length of trailers only. In other words, the length of the front of the car no longer affects the pulling of goods.

So since the 1980s, there have been more and more long-headed cards in the United States. Later in the 2007 movie, Optimus Prime, alas, became a long-headed card.

Before 20 16, the national standard has always limited the length of the whole vehicle.

China's old national standards 1989 and 2004 (GB 1589-89, GB 1589-2004) are the same as those of the early United States, with limited total length. It was not until 20 16 that the new national standard (GB 1589-20 16) relaxed the standard and allowed long-end articulated trains, which were called "semi-trailers" in the local dialect, with an excess of1m.

This "1m" is reserved for the front of the car. However, the new national standard has only been issued for five years, so at present, the mainstream cars in China are all flat-headed. It's not like you have to change trains as soon as you get out. Trucks are expensive, okay? It's always the price of Mercedes.

China and the United States have different geographical conditions.

There are many mountains in China, which requires high flexibility for trucks. In addition to laws and regulations, the geographical conditions of China and the United States also determine whether to use a long head or a flat head. According to the Chinese government website, the plain only accounts for 1 1.98% of the land area, and the mountainous area accounts for 2/3.

In other words, our country is actually mountainous and the road conditions are complicated. Flat-headed trucks are shorter, so they are much more flexible when turning, which is obviously more suitable for home use. Similar to domestic ideas, there are Europe and Japan. The roads in Europe are narrow, and the mountainous areas in Japan need flexible trucks, so there are more flat heads.

America is very dull and doesn't care about flexibility.

About half of the land in the United States is plain, and the roads are relatively straight, so turning is not necessarily how to turn. Of course, the question of flexibility is not entangled, is it?

Like many muscle cars, the reason is the same. Yang Zaishun's paper published in Automobile and Accessories magazine is also mentioned in Long Trucks in Small Market.

Most goods in North America are transported by heavy trucks, where the land is vast and the population is sparse, and the road conditions are good. Drivers often drive at high speed. Moreover, the wind resistance of the long head is smaller, which can save 10% to 15% of oil money. So the long head is really more suitable for use in the United States.

The income levels of truck drivers in China and the United States are different.

Finally, the income level of truck drivers in China and the United States also determines whether they have long heads or flat heads. American truck drivers have high incomes and pursue safety and comfort.

How do you say this thing? The above mentioned Chen Zhou's paper "American Female Truck Drivers with High Income and High Risk" published in "Looking at the World" magazine.

The average annual income of American families is about 50,000 dollars, and the annual income of truck drivers alone is 40,000 to 68,000 dollars (data of about 2065,438+06). This is about 260,000 to 440,000 RMB.

Since the income is not bad, American drivers have the energy to pursue safer and more comfortable trucks. There is a little white saying: after they are full, they pursue more.

Just now, the paper "Long Trucks in Niche Markets" mentioned it.

The long head has a longer collision buffer than the flat head, which is safer in collision; The cab with a long head has more space and is farther away from the engine, so there is less heat, noise and vibration transmitted to the cab. That is: safer, more comfortable and more space, which American drivers certainly prefer.

Domestic truck drivers have low income and pursue high efficiency.

Domestic truck drivers are not so relaxed. The Report on the Credit Development of Working Class in China (20 17) issued by the China Family Finance Research and Research Center of Southwestern University of Finance and Economics mentioned that the average income of domestic working families is154,000 RMB.

Regarding the income of truck drivers, we can refer to Wen Xiaoyi's paper published in China Workers, and pay attention to the living conditions of truck drivers. It says: In 20 16 years, 7 1% truck drivers in China earned less than 654.38+10,000 yuan a year, which is not easy.

If you deduct living expenses, fines and loans, it will be even less. We should earn more money, right? The higher the value of a trip, the better the truck is a flat-headed truck. Comfortable and safe, endure it first, start a business hard first, and wait until you have money, okay?

The reason why American trucks have long heads and domestic trucks have flat heads.

To sum up, the United States relaxed its laws and regulations on long-headed trucks in the 1980s, and its own road conditions were relatively flat, and drivers' income was high, which was liked by drivers and allowed by laws and regulations, so they all grew. The national standard for domestic long-headed trucks has only been relaxed for five years and will not be changed at once.

Moreover, the roads are more complicated, there are not so many plains, there are many more mountains than we thought, and the income of drivers and brothers is not particularly high. Therefore, it is more inclined to flat-headed trucks with flexible turning and higher efficiency.
