Shinalar avtomobillarning muhim qismidir. Avtomobil shinalarida 10 dan ortiq turdagi belgilar mavjud. Ushbu belgilarni to'g'ri aniqlash shinalarni tanlash, ishlatish va parvarish qilish uchun juda muhimdir. Bu haydash xavfsizligini ta'minlash va shinalarning xizmat qilish muddatini uzaytirish uchun katta ahamiyatga ega. Quyida hamma uchun tushuntiriladi
1. Shinalar texnik xususiyatlari: Texnik xususiyatlar shinalar geometrik parametrlari va jismoniy xususiyatlarining ramziy ma'lumotlaridir. Shinalar xususiyatlarini ifodalashning uchta usuli mavjud: A. Metrik tizim (m); B. Metrik tizim (m); B. Metrik tizim; C. Britaniya tizimi; Britaniya tizimi shinalarining texnik xususiyatlari ko'pincha raqamlar to'plami bilan ifodalanadi. Birliklar dyuym. O'rtadagi harflar yoki belgilar alohida ma'noga ega:
2. Tire structure: "R" means radial tire, "D" and "一" mean bias tire.
Others: "XL" means locally reinforced tires, "TG" means engineering tractor and motor grader tires (for off-road use), and "NHS" means off-road use tires.
3. Layer level: Layer level refers to the nominal number of plies in the tire rubber layer, which is not completely consistent with the actual number of plies, and is an important indicator of tire strength. The level is marked in Chinese, such as level 12; and the level is marked in English, such as "14P.R", which means level 14.
4. Cord material: Some tires are marked separately, such as "nylon" (NYLON), which is generally marked after the level; some tire manufacturers in the world mark after the specifications, and use the first letter of the Chinese pinyin, such as 9.00-20N, 7.50-20G, etc., N stands for nylon, G stands for steel wire, M stands for cotton thread, and R stands for rayon.
5. Load and air pressure: Generally indicate the larger load and the corresponding air pressure, the load is in "kg" as the unit, the air pressure is the tire pressure, and the unit is "kPa".
6. Rim specification: indicates the rim specification that matches the tire. It is convenient for practical use, such as "standard rim 5.00F".
7. Balans belgisi: U rangli kauchukdan yasalgan va shinaning juda engil ekanligini ko'rsatish uchun yon devorga bosilgan. Butun shinaning muvozanatini ta'minlash uchun yig'ish paytida to'g'ridan-to'g'ri valfga qaragan bo'lishi kerak.
8. Aylanish yo‘nalishi: shinalardagi naqsh, ayniqsa, haydash paytida suvni oqizish va sirpanishning oldini olish uchun juda muhimdir. Shu sababli, assimetrik naqshli yoʻltanlamas{2}}yoʻl transporti shinalari koʻpincha strelka belgilari bilan jihozlangan boʻlib, ular yopishtirish va sirpanishdan himoya qilish imkonini beradi. Agar u noto'g'ri o'rnatilgan bo'lsa, u samarasiz bo'ladi.
9. Aşınma chegarasi belgisi: Shinaning bir tomonida shinaning aşınma chegarasini belgilash uchun rezina chiziqlar va bloklardan foydalaning. Shinaning eskirishi ushbu belgi holatiga yetgandan so'ng, uni o'z vaqtida almashtirish kerak, aks holda shinalar etarli darajada mustahkamlanmaganligi sababli o'rtada yorilib ketadi.
10 Production batch number: A set of numbers and letters are used to indicate the year, month and quantity of tires. For example, "98N08B5820" means the 5820th tire produced in Group B in August 1998. The production batch number is used to identify the degree of newness and storage time of the tire.
11. Savdo belgilari: Savdo belgilari shinalar ishlab chiqaruvchilarning belgilari, jumladan, savdo belgisi matni va naqshlari boʻlib, ular odatda koʻzga tashlanadigan va{1}}koʻzga tashlanadigan va aniqlash oson. Ularning aksariyati ishlab chiqaruvchining nomi bilan belgilanadi.
Har bir inson bu belgilarni biladi, ular kelajakda shinalarni aniqlash va texnik xizmat ko'rsatish uchun foydali bo'ladi.
