There is a direct relationship between the quality of the tires and the length of the mileage and whether the locomotive is proper and the operation is correct. The length of the tire's service life, although it has a certain relationship with the quality of the tire, but it is also inseparable from the correct use and maintenance, so the following problems in the use of the tire:
1. The use of tires for the intended use, for example, high-pattern tires for paddy operations, cannot be used in place of road transport operations, otherwise it will increase the vibration of the locomotive and reduce the life of the tire by 20%. More than 35%. Conversely, if the tractor is used in the field, if the driving wheel does not use high-pattern tires, the tire life will be greatly shortened due to the high slip rate.
2. Do not follow the rules for inner and outer tires and linings. If the size of the inner tube and the lining is not the same as the size of the casing, or install the used inner tube and lining in a new or repaired casing, or install it in a bad tire. New inner tubes; or inner and outer tires with different cross-section widths, which affect the life of the tire.
3. Tire pressure is too high or too low, which is one of the most common reasons for significantly shortening tire life. When the slack is used for tractors, they are used for short-distance transportation. If there is no spare tire with the vehicle, if the operator finds that the air pressure is insufficient on the way, it is often the gas after arriving at the destination. Some operators do not consider the difference between old and new tires and the difference in temperature between different seasons, causing an explosion due to excessive tire pressure.
4. Violation of the tire disassembly regulations Because the operator does not operate according to the tire disassembly regulations, the outer tire edge damage accounts for 10% to 15%, and the inner tube damage accounts for 8%-15%, which will shorten the tires than normal use time 12 %—16% or more.
5. The radial overload of the vehicle's overloaded tires is one of the main reasons for the early retirement of the tires. According to the tire scientific research data, the load can be doubled after the load is lower than the allowable value of 3%; the overload is 40%, and the tire life can be shortened by 50%.
6. Exceeding the allowable speed of the tires, the vehicle speed is assumed to be 60km per hour for the standard life of the tire. If the hourly speed is increased to 90km, the service life of the tire is shortened by 50%. If the vehicle is driven at a high speed for a long time, it will cause the tire carcass to stratify and tread. It is prone to thermal cracking in the carcass stripping and tire casing.
7. The maintenance and repair of the tires is not timely. Some individual transport professional households only pay attention to the time to catch the money, and there are serious wounds on the tires and they are not repaired in time. Most tires can be replaced 2 to 3 times, but when worn to the limit, they cannot be repaired once.
8. From time to time, some motor vehicle drivers are exchanged for a long time in the new car, and even if the individual wheels are close to scrapping, there is no left and right crossover. If you use snow chains during operation, you should also notice that the left and right elastics are consistent, and the sliding sections should be removed immediately.
9. If the front and rear axles are deformed and worn on the front axle, the rear axle, the axle axle, the suspension axle, etc., the impact on the life of the tire is greatly affected. These faults almost shorten the normal life of the tire by half, so it is necessary to check frequently. Handle in time.
10. If the load is unevenly distributed, if the goods are not evenly distributed, not only can some of the tires be overloaded and accelerated, but also the tires can be easily crushed, and it is easy to cause rollover accidents and affect personal safety. In the case of a towed trailer, it also affects the adhesion of the front drive wheel to the ground.
11. The places and places where the vehicles are parked are not suitable: first, the tires are stained with oil, second, the tires are exposed to acid and alkali, the third is exposed to long-term exposure, the fourth is close to the fire source, and the fifth is the ground with sharp stones and sharp points. Hardware, these will hurt the tires.
12. If the tires are not suspended, especially if the tire pressure is lower than the specified value, due to the stable deformation, the tire carcass will be delaminated and broken in individual cases, thus making the tire life much longer. shorten.
13. Driving skills are not high. Many new drivers often have frequent emergency braking during driving due to lack of experience. They often take emergency start and high-speed steering and turning, trapping and traction resistance are too high, wheels are slipping for a long time, or sloppy Through obstacles, some will not choose the road surface and the corresponding driving speed, which will also affect the life of the tire. If you drive on cobblestone, gravel, and gravel roads, the life of your tires is 30% shorter than on asphalt roads. If the speed at the turn is 10% higher than the travel speed, the wear rate of the tread will increase by 40%-50%. When the ambient temperature reaches 36 ° C, if the speed of the locomotive reaches 90 km, the service life of the tire will be shortened to 70%. (Danshan)
