Tire is a round elastic rubber product that is assembled on various vehicles or machinery and rolls on the ground. Usually installed on the metal rim, it can support the car body, buffer the external impact, achieve contact with the road surface and ensure the driving performance of the vehicle.
Tires are often used in complex and harsh conditions. They are subjected to various deformations, loads, forces and high and low temperatures during driving, so they must have high bearing performance, traction performance and cushioning performance. At the same time, it also requires high wear resistance and bending flexibility, as well as low rolling resistance and heat generation.
Tire development history
The birth and development of the automobile is a great achievement of the world's scientific and technological progress and an important footprint of human progress, which has enabled mankind to enter the automobile industry era from the carriage era. In the early days of the automobile, in order to meet the comfort, handling stability and power of the automobile, scientists constantly carried out research and innovation, and constantly promoted the progress and innovation of the tire industry.
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.
1888, John Deng Lupu made rubber into a tube, wrapped it around the edge of a wooden wheel, and then filled it with gas. The elasticity of this tire not only fully absorbs the vibration, but also protects the mechanical properties of the car body. The world's first pneumatic tire was born, and this technology was first applied to bicycles.
189 1 year, Andrew Michelin developed a detachable bicycle pneumatic tire.1In June, 895, Michelin brothers applied pneumatic tire technology to the automobile field.
