In a variety of vehicles or machinery on the assembly of the grounding ring rolling circle elastic rubber products are typically installed in a metal wheel rim, to support the body, Huanchong external shocks, to achieve contact with the road and to ensure that the vehicle performance. Tire often complex and demanding conditions of use, which bear all the driving deformation, load, force and high temperature effects, it must have a high bearing capacity, traction, cushioning performance. Also requires a high abrasion resistance and flex resistance and low rolling resistance and heat resistance. World consumption of half the amount of rubber used in tire production.
A Brief History of the tire
The earliest tires
The first tire is made from wood, which from the chariot in ancient China and abroad can be seen on the carriage of a gentleman.
Later, when explorer Christopher Columbus was the second time in 1493-1496 to explore the New World arrived in the West Indies island of Haiti, we found that the local kids are playing the rubber lump, which made him surprised. Later, he put this thing back to the motherland, wonderful, years later, the rubber has been widely used, from the wooden wheel gradually became hard rubber. But this time, but still solid rubber tires, and go up also uncomfortable, but also a great noise. Until 1845, civil engineer born in Scotland in R · w · Thomson invented the pneumatic tire , and to “carriage wheels and other vehicle modified” in the title, won the British government’s patent. On 10 December the same year, the first pneumatic tire was born. The first people to buy call lists pneumatic tires, is a noble, the total price of four tires for the forty-four pounds two shillings. 1847 “Scientific American” magazine Thomson introduced the pneumatic tire, called the epoch-making improvements. However, when the British, too much emphasis on the traditional gentleman of, in order to protect the carriage to limit the development of steam cars, the speed of vehicles in urban areas is limited to speed 2mile (about 3.2km), suburb of 4mile (about 6.4km). Thus, Thomson’s invention would have no market, therefore, will slowly be forgotten. In other words, Thomson’s first tire revolution, not to mankind, like the bright sun, because human beings seem to be not subjected to the dark head. But the sun is always out, because all human beings and all things need it, 40 years after 1888, when the veterinary doctors in the Irish Grand human J · B · Mr. Deng Lupu made pneumatic tire patents. At that time, J · B · Mr. Deng Lupu 10-year-old son, Johnny bought a three-wheeled bicycle, but also because it was the tires are made with a hard rubber solid tires, so full of stones in the road walking very comfortable, inspired his son complained about the inspiration for Mr. Deng Lupu, therefore, be forgotten again forty years the advent of pneumatic tires. With the progress of the times, Mr. Deng Lupu invention of pneumatic tires on the bike has been quickly applied, and to move quickly to the automotive sector, the development of the world’s automobile industry made a great contribution.
Pneumatic tire
The beginning of the pneumatic tire, using a canvas coated with rubber when the carcass, because the canvas of the vertical lines and horizontal lines cross each other when walking due to tire deformation, leading to friction between the line, so lines can easily be wear off, then the tire can only run 200-300km. 1903, J · F · Mr. Palmer invented the twill textile, twill textile of this invention led to the development of cross-layer tire so the tire’s life took a big step forward cross. Because the matrix will not fork-walking caused by tire friction, tire cord is not easy to wear off, so life is greatly extended. 1930, Michelin produced the first tubeless tire; 1946 and invented the world-famous tire. Therefore, the development of the tire is gone through a long journey, in which a long night, I do not know how much to pay on behalf of people of the hard work and superior intelligence.
Tire function
Tyre is a product, it is a high-tech composite products, it contains from 200 different materials and products, consisting of about 20 kinds of components; tire is a culture, it contains intelligent and human wisdom; tire is a safe, it is closely related with the auto age, everyone’s life, is you and I have to go cautious consumer. But in the end for automotive tire service.
Tires on a car one of the most important component parts, and its role are: to support the full weight of the vehicle to withstand automotive load; transmit traction and braking torque, to ensure adhesion with the road wheels; mitigate and absorb the car in moving shock and impact, to prevent auto parts subject to severe vibration and early damage to adapt to the vehicle when driving high-speed performance and reduce noise, to ensure driving safety, handling and stability, comfort and energy economy.
