In the 1000 years after the ancient carriage, this kind of carriage used for long-distance transportation became the main means of transportation in the world. Of course, these carriages are not only used for pulling goods, but also for carrying people on long-distance trips. Four-wheeled wagons transport people from one place to another quickly, which makes people really feel the convenience brought by wagons. The advantage of a four-wheeled vehicle is its heavy load and smooth running. The disadvantage is that wagons need relatively flat roads. In its heyday, the Roman Empire had a good 80,000-kilometer flat road, which made this kind of carriage popular. After the fall of the Roman Empire, roads are falling apart after centuries of disrepair. At this time, the most practical is a two-wheeled vehicle, because it can travel on rugged terrain.
At first, the carriage was just a box with windows, suspended by a belt on the frame without spring plates, and the passengers sitting opposite had to endure constant shaking and jumping. In the following centuries, this means of transportation was replaced by a number of more sturdy, lighter, more beautiful and more efficient carriages. /kloc-in the 0/7th century, the four-wheeled public * * * post coach undertook almost all the long-distance passenger transport tasks, which brought prosperity to land travel, and the exquisite private carriage became a symbol of royal status. The most luxurious British royal carriage was built for King George in 1763, which is called "the most magnificent carriage ever". However, the speed of the carriage is still unsatisfactory. A mail truck traveled 375 kilometers on the best expressway at that time, and it took 23 and a half hours at the earliest.
People hope to invent a power machine that is more durable and stronger than horses, so that the wheels can turn faster. At the same time, it is also necessary to have a smoother and more reliable road surface for four-wheeled vehicles to walk on. Soon after, in some parts of Britain and the United States, some imaginative people began to experiment with steam as power and steel as roads.
1904, the four-wheeled horse-drawn post car struggled with the steam train and finally failed. The last famous post car between snooker and Gough, a wealthy town in Nevada, USA, stopped. The golden age of carriage is over.
China carriage
Archaeological excavations in Anyang Yin Ruins show that China had already used two-wheeled carriages in the late Shang Dynasty. The horse-drawn carriage in China, the source of tourism, has always been a concerned but unresolved issue. In this regard, the academic community is arguing endlessly. Some scholars in China hold the view that the carriage originated in China, while others hold the view that the carriage in China originated in the grasslands of Central and Western Asia or Eurasia. Among them, the most representative view is that Sumerian wagons originated in the middle of the 30th century BC and were introduced to China in the late Shang Dynasty.
