1493- 1496, Columbus explored the new continent for the second time. When he arrived at the island of Haiti in the West Indies, he found a rubber ball that children were playing with and took it back to the motherland. Since then, people began to research and develop rubber.
1839, Goodyear developed "Rubber Vulcanization Technology", and successfully developed rubber that will not decompose at any temperature below the boiling point. Thirty-eight years after Goodyear's death, Frank Kabring named his tire company Goodyear to commemorate Charles Goodyear, who made great contributions to the American rubber industry.
1845, an English blacksmith obtained the patent for the first rubber pneumatic tire. He made an inner tube out of rubber-coated canvas, covered it with leather to resist the wear of rough roads, and then filled it with air to make the first automobile tire. However, because Britain emphasized the traditional middle class at that time, everyone liked to ride in a carriage, and his invention was gradually forgotten.
1888, Englishman john boyd Deng Lupu obtained the patent of pneumatic tire again. Deng Lupu invented pneumatic tires by pure coincidence. He bought a tricycle for his 65,438+00-year-old son Johnny, but Johnny complained that it was uncomfortable to walk on the stone road with solid tires made of hard rubber, which inspired Deng Lupu. Deng Lupu made rubber into a tube, wrapped it around the edge of a wooden wheel, and then inflated it. The elasticity of this tire not only fully absorbs the vibration, but also protects the mechanical properties of the car body. This is the first time the bicycle has been inflated.
189 1 year, Andrew Michelin developed a detachable bicycle pneumatic tire.1In June, 895, Michelin brothers applied pneumatic tire technology to the automobile field. At first, all pneumatic tires used rubber-coated canvas as the carcass, because the longitudinal and transverse lines of canvas crossed each other, and the tires would be deformed when walking, and the lines would rub against each other and soon wear out. The original tires can only guarantee 200-300 kilometers.
1903, Mr. J.F. Pama invented twill textiles. This product has good wear resistance and the rope is not easy to break. When it is applied to the field of tires, the service life of tires can be greatly prolonged. This invention contributed to the emergence of bias tires. Because of its excellent characteristics, bias tires are still in use until now.
Early tires had no patterns, which greatly affected the safety performance when driving on wet roads. 1904, Continental produced the world's first automobile tire with patterns, mainly horizontal stripes and vertical stripes.
1946, Michelin Company invented the radial tire, which is the tire we use most today. This design method improves the service life of tires by 30 ~ 50%, reduces the fuel consumption of automobiles by about 8%, and has the characteristics of more comfort and lower rolling coefficient. The use of radial tires has brought a real technological revolution to the tire industry.
In 2002, Marpai German R&D Center invented the world's first run-flat tire, also known as a flat tire. The run-flat tire can still ensure normal and safe driving under the ordinary pricking and scraping conditions. According to statistics, more than 42% of traffic accidents on expressways are caused by puncture, and high-speed puncture occurs above 150 km/h, and the mortality rate is close to 100%. High-speed puncture has become the "number one killer" of highway accidents. At present, almost every tire brand has technology related to flat tires. The invention and popularization of run-flat tires greatly improved the driving safety.
