Wheel Development And Evolution
- Aug 09, 2018 -

A "small squat" that was originally invented by people, which is characterized by sliding on the ground by means of a slide bar. It was still very difficult to pick up such sleds on the wilderness hills with few roads. One day, the wind was so strong that it was found that under the wind, the smooth stones or logs rolled faster than anything else. This natural phenomenon has a great inspiration for people. People use a stone axe to cut the logs, and cut a round hole in the middle of the cut round hole, and then put a thin wooden stick in the hole to put them. connect them. In this way, a roller skid was successfully manufactured, and it was much lighter to use to drag things than in the past. The roller appeared around 2000 BC. When such a roller is used to carry too heavy items, it will be fractured. Therefore, it has been thought that the wheel is covered with a copper band or a hoop. According to legend, in about 3000 BC, the Central Asian region used the wheeled car, but at that time the civilized Egypt did not know that it was still using the rolling wood for hauling goods. In 1600 BC, the North Hexagon The Sri Lankan attacked Egypt with a horse-drawn chariot, which surprised the Egyptians. Since then, the Egyptians have also begun to use the wheeled car. The spokes and rims were first used to reinforce the wheels. But at the time it was all wooden. Later, with the advent of steel, the wooden wheel developed into a steel wheel, plus rubber tires, filled with air, and the wheels were perfect.


Let us take a look at the debates of archaeologists for the time being. Let's first look at their consensus:


The predecessor of the wheel is the wheel used for making pottery. The ancients used it to make pottery in batches [01 made pottery on the pottery wheel], which is the earliest crafts and containers of mankind. The simplest pottery wheel only needs a pair of disc-shaped wheels. A shaft is placed between the discs. The shaft stands upright. The potter uses one foot to rotate the lower disc and one hand puts the soft clay on the top wheel. In the plate, plastic kneading.


The earliest wheels of Mesopotamia were just round plates, and the shafts were firmly nailed together. By 3000 BC, the axle had been attached to the trolley and the wheels were not directly connected to the body. Soon after, there were wheels with spokes. This primitive trolley is awkward, but much better than the shoulders and beasts (usually the scorpions) of the people who have been using them before.


The wheels have long been used to make tanks. This type of chariot was first used to break into enemy formations, forcing the enemy to collapse; later, when used as a combat station, the chariot soldiers could stand on the chariot and throw javelin at the enemy, launch a bow and kill the enemy.
