What are the classification of tires
According to the different structure of the tire body can be divided into inflatable tires and solid tires. The vast majority of modern automobile pneumatic tires. According to the air pressure in the tire, the tire can be divided into three types: high pressure, low pressure and low pressure. Various types of vehicles commonly used low-pressure tires. According to the different structure of the pneumatic tire, it is divided into two types: inner tire and tubeless tire. Tubeless tire. According to the different arrangement of tire inner ply and buffer layer, the tire can be divided into two kinds: radial tire and skew tire. Radial tires are widely used in cars. Tire side are marked.
According to tire use
For example, in Chinese tire tire rim national standard, American standard manual, the European tyre and rim, the Japanese tire standard and international standard is the tire to use classification, can be divided into the following types:
The car tire is installed in the car tire, it is mainly used for road speed exercise, more than the maximum speed of up to 200 km / hour, requirement of ride comfort, low noise, has excellent maneuverability and stability. Most of the radial structure of the tire structure. According to the requirements of the speed is divided into different series, in the standard and manual of the common 95, 88 series of bias tire, the 80, 75, 70, series for radial tire.
Light duty truck tire - usually a 16 - Inch tire with a rim of a diameter of less than 9 inches and above. This kind of tire is mainly in the road, the speed can reach 80 ~ 100km/h.
Truck and bus tires are typically 18 to 24 inches in diameter, with a width of more than 7 inches across the surface of the truck, dump truck, a variety of special and Trailer tires. Its driving surface is more complex, there is a good asphalt road, there are poor gravel road, dirt road, muddy road, ice and snow road, and even no road conditions, driving speed is generally not more than 80km/h.
Engineering machinery vehicle engineering machinery tyre, engineering machinery tyre is installed in special operations, such as loaders, bulldozers, excavators, land leveling machine, roller and stone working machine etc.. Driving speed is not high, but the use of road conditions and load performance requirements. The tire is mainly the use of oblique tire structure, but such as France, its wheels (Cantonese, Mandarin called Michelin) companies also use meridian structure. The classification of tire width can be divided into two series: standard tire and wide base tire.
Off-road vehicle tires - off-road vehicles for front and rear wheel drive. Off-road vehicle tires mainly runs on bad roads such as desert, mud, soft soil or other non road tires with higher requirements, through the performance, off-road tires are often used in low pressure, and some also use pressure to adjust the tire, the tire pressure according to the size of road conditions. In order to improve the ride performance of the cross section, the widening of the tire section and the width of the rim, and the reduction of the diameter of the rim are generally used in order to increase the grounding area and reduce the ground pressure. In addition to the oblique tire structure, the tire structure.
Agricultural and forestry machinery tire - agricultural tires are primarily used in tractors, combine harvesters and other agricultural implements. Forestry machinery tires in forestry tractors and machinery for forestry, logging, forestry, mining and logging shovel operation. The characteristics of these two kinds of tires are speed requirements is not high, but the use of harsh conditions, often running on the path of the field situation is bad and hard stubble or stone mountain, even without the road, the tire can be scratched or cut. Another feature is the intermittent operation, the mileage is short, but the use of a longer period, so the requirement of tire has good resistance to cracking and aging resistance. The tire is inclined to the main structure, but also the meridian structure.
Industrial vehicle tyres - pneumatic tires, semi solid tires and solid tires for industrial vehicles. Battery car tires, truck tires, divided and flatbed tire etc..
Motorcycle tyres - Tyres for motorcycles. Including motorcycle tires, light motorcycle tires and small diameter motorcycle tires.
Aircraft tyres - pneumatic tyres for aircraft.
Special vehicle tyres - including tires, tires, tanks and artillery armored car tires, tires, tires and other explosion-proof vehicle desert.
Pneumatic tyres - pneumatic tyres for bicycles, tricycles and trolleys.
Electric vehicle tyres - Tyres for electric bicycles.
According to the structural design
Tire, radial tire. The fundamental difference between the radial tire and the oblique crossing is that the carcass. Cross ply tire carcass is cross ply; and radial tire carcass is cross polymer multilayer materials, steel cord is its top layer by number of steel wires, can reduce the probability of tire punctured by a foreign body.
The diagonal line of the skew tire is arranged in a diagonal line, hence the name. The utility model is characterized in that the strength of the tread and the tire side is large, but the sidewall stiffness is large, and the comfort is poor. Because of the high speed between the moving and the friction between the plies, the utility model is not suitable for high speed driving. With the continuous improvement of radial tire, bias tire will be basically eliminated.
The alignment direction of the radial tire is the same as that of the tire radial section. When the tyre is subjected to a large tangential force when running, in order to ensure the stability of the cord, the outer layer is provided with a plurality of layers which are made of high strength, not easy to stretch
