Who invented the first pneumatic tire in 1945?
Andre Michurin of France and Edward Michurin two brothers meters 1892 Xu Lin invented an inflatable rubber tire can be removed, the past only specialized repairman can deal with blowout accident, now generally a quarter can be repaired. This invention influenced the whole world. In 1895, the Xu Lin brothers, for the first time, sent the "lightning" car with removable tires to Paris - er - Paris car plug. The tire car has officially stepped onto the stage of history and has spread rapidly all over the world.
As early as in 1836, Belgian Diez had put forward the viewpoint of pneumatic tire. In 1845, British civil engineer Meader Sykes Robert W Thompson invented with leather wrapped, filled with air or horsehair tires, but no actual use. In 1888, living in Scotland Ireland Belfast veterinarian John Bird Dunlop, his son saw the solid rubber wheel bike on the stone bumps on the road is very powerful, so with a valve charge through the tube, the outside coated with rubber protection layer, made a pneumatic tyre. The air around the wheel, to repair the puncture tube, must first be painted with benzene rubber foam down, then coated with rubber. The new tire was laughed at at first, but his son got the first prize in the race, so the invention was taken seriously. Dunlop patented his invention, gave up his veterinarian career, built the world's first tire manufacturer, and began producing rubber tires. From 1894 onwards, the early mass production of "Hildebrand" and "wall Miller" brand motorcycles officially used Dunlop tires.
In 1908, Xu Lin company developed a dual wheel, can effectively solve the problem of heavy truck tire load. In 1937, Xu Lin & Co. developed a radial tire, named "fly cage", whose tread was reinforced with multiple plies and tightened with a layered steel cord. The tire cord layers are vertically arranged with the steel wire of the tyre, thereby greatly improving the stability of the running direction of the tyre. In 1981, the British company Dunlop invented a new type of tire, in the case of perforation, the car can continue to drive, and the tire will not be removed from the rim. The inner surface of the crown is coated with poly gel, which is both sealant and lubricant. This kind of tyre has a safe life span of only 25 thousand kilometers
