The tire is being a vehicle or machine assembly ground rolling side of the annular elastic rubber products usually is installed on the metal rim, can collect the bearing body, outside of the buffer, blow, achieve take road contact and ensure the running performance of the vehicle. Recently, Michelin tires on tire knowledge class, let everyone right consciousness tire.
A variety of Tire Valve characteristics of tire knowledge class teaches you comprehend the basic knowledge of tire, ask: correct understanding of tyre without any good?
The correct understanding of the tire, to diverging conditions determine tire conditions, real-time replacement and adjustment, ensure the normal running of Enron and convenience.
Are commonly used as flat tire, tire category is divided into two categories, the first category for bias tire, also known as the common tire. A carcass ply and a buffer layer, adjacent layers of Cord Cross, and tread the core line is less than 90degrees angle alignment of the pneumatic tire. That kind of tire vertical rigidity, for being ordinary roads and speed.
Second kinds of commonly used tires for female meridian tire, the meridian tire commonly known as the” steel wire tyre”. The meridian tire characteristics as the cord is not mutually crossed, but take the tire section connected to line, to earth’s female meridian so arranged, cord angle is small, the surrogate China Normal is 0 DEG, carcass connections between without maintaining intersection, when the tire in driving course, crown around when the force delete great, would constitute Zhou Xiangshen gallop, carcass into a radially split. Because of this meridian tire buffer layer adopts are circumferentially arranged to deal with cord layer, and carcass cord angle90 degrees intersect, the normal 70to 78 degrees, which one can hardly reach Chi rigid annular zone. The spare tire is fixed, restrict the tire circumferential deformation, the buffer layer by Zero tires 60% to 70% when force. Be a meridian tire main stress components. It is called the radial tire belt. Bias tire main stress components in the buffer layer, the80% to90% period when the force by the carcass ply burden. Thus, the meridian tire belt design is very important, must have good rigidity, can be used in multistory large angle, high strength and not difficult to stretching the fiber materials, such as steel or glass fiber.
Tire by what parts forming
1: tire, tire tread, the sidewall, buffer layer, ply and bead formation. The car is running for suffered all kinds of work force.
In 2, the sidewall: sidewall tire lateral ply outer layer, for protecting carcass.
3, ply ply is: in vitro by juxtaposing hanging plastic curtain female line is formed in the fabric layer, tire force skeleton layer, to assure tires have the necessary strength and dimensional stability. Buffer layer for bias tire surface and between the carcass ply cloth curtain layer or layer surrogate blog, used to buffer the external force, protecting carcass, promotional table to ply between the adhesive.
In 4, the bead: bead tyre is installed on the rim portion, a bead core and a bead pack cloth form, its fixed tire use. Tire specifications to tire outside diameter D, bead diameter or rim diameter D, section width B and flatter than size to represent, are in inches.
5, automobile tires automobile tires: Rubber and fiber material and the normal metal materials composite products, manufacturing process is the machine processing and the inverse when integrated course. Rubber and the common agent mixing after extruded tread ply made; by rolling, cutting, fitting into drum band or cord rolls; steel wire by joint venture, packets of plastic molding for the bead; then the semi-finished products are shaping machine are combined into a green tire vulcanizing machine, are metal model, through vulcanization made of tire products.
Tire above data represents what mean
Tire specifications: specifications of tire geometry parameters and physical properties of the labeled data. Tire specifications commonly used digital representation of a group, a digital representation of the section width of a tire, a digital representation of rim labyrinth, are in inches. The middle letter or symbol has no special meaning:” X” said high-pressure tire;” R”,” Z” said female radial tire;” a” said low pressure tire.
Level: level refers to the tire rubber layer in cord plies in nominal, and ply rating is not thorough differences, is the important target of the tire strength. Level with foreign markers, such as the 12 level; with English mark, such as”14P.R” is the 14layer.
Curtain line data: no tire individually marked, such as “nylon” ( NYLON ), normal standard is level; there are no tire manufacturers label are specifications, smuggling car using the first letter of Chinese Pinyin representation, such as9.0020N,7.5020G, said N nylon, G said, M said, R thread wire said one silk.
Load and pressure: normal marking maximum load and considerable pressure, load” kg” as the unit, air pressure that tire pressure, the unit is ” kpa”.
Rims: representation and is matched with the tyre rims. Convenient facts using, such as”5.00F scale rims”.
Balanced markers : color rubber mark shape, India is fetal side, said tire where light, when assembled as against the Tire Valve, to ensure that the spare tire balance.
Rolling direction indicators: Tire markings to travel outside the drainage anti-skid special key, so the pattern differences wrong misnamed off-road vehicle tires used arrow marker assembly rolling standard indicators, to ensure that the design of the force, and antiskid performance. If the fault is removed, spoil things by excessive enthusiasm.
Wear limit markers: the side of the tire with a rubber strip, block marked tire wear limit, once the tire wear to the marker position when the real-time change, otherwise it will because of strength is not enough route.
Production batch number: with a group of figures and letters, said tire manufacturing date and amount. Such as”98N08B5820″ said in 1998August B group produces5820th tires. Production batch number used to identify tire new level and storage time.
Grade: grade is the tire manufacturer’s markings, including trademark words and patterns of normal, more prominent and brilliant, it is difficult to identify. Most manufacturers factory name is labeled with.
