Ancient carriage wheels, solid rubber tires
1839 Charles? After Goodyear invented vulcanized rubber, rubber tires began to be widely used in various vehicles. But until the end of19th century, the rubber tires installed on cars were all solid. This kind of tire has poor ability to absorb road impact, which leads to severe vibration and loud noise when the car is driving. Although the speed was very slow at that time, in order to cope with the impact of the road, the suspension and body had to be designed very unwieldy to increase the mechanical strength.
The birth of pneumatic tire
1845 Scottish Robert? Robert William Thomson first invented the pneumatic tire and obtained a patent. However, due to the limitation of rubber production technology and the development of automobile industry at that time, his pneumatic tire technology was not widely used.
After the technology of pneumatic tires was put on hold for 42 years, another Scotsman, John? Deng Lupu invented the first practical tricycle pneumatic tire in 1887. 1889, a cyclist named Willie Hume achieved excellent results in the race using Deng Lupu's pneumatic tires, and pneumatic tire technology began to become a household name. The earliest pneumatic bicycle tires 189 1 Edward and Andrew? Michelin (Edward &; André Michelin) brothers invented pneumatic bicycle tires, which can be disassembled and replaced in fifteen minutes. This product was quickly adopted by cyclists at that time.
1895, they first developed pneumatic tires suitable for cars and equipped them on their own racing cars. In the Paris-Nielsbohr-Paris competition, the two brothers went into battle in person and ran the whole race brilliantly, causing a sensation in Paris. With the technical advantages of pneumatic tires, Michelin tires have been successful in all major international automobile races from 1900 to 19 12.
