1. Under certain load and driving environment conditions, the development of forklift tires has a suitable tire pressure. When the tire pressure is lower than the industry standard value, the radial deformation of the tire can increase. Excessive use of bending on both sides causes the tire crown to be grounded on both sides, the inner wall of the sidewall is compressed, and the outer wall of the sidewall is stretched, resulting in the deformation of the Chinese tire cord. The influence is greater, and the stress is alternating. Periodic compression deformation will speed up the fatigue damage of the cord, which will increase the relative slippage between the tire ply and the economic development level between the tire and the ground working environment. The heat generated by the analysis of the main friction problems will continue to increase. The use of different temperature changes sharply increases the cost and effectively reduces the tensile strength of the rubber. The cord is loose and partially delamination. When encountering obstacles, the students themselves will experience a puncture when they are severely impacted. The recessed part of the tire tread is easy to be embedded in the nails and stones on the road surface, causing mechanical damage. The rolling resistance analysis of the carcass can be increased by increasing the fuel consumption. The uneven tread pressure causes serious wear of the tread, causing a "bridging effect", and the tread is jagged or wavy. The research results of the test method show that when the tire company's air pressure cannot be lower than 20%-25% of the standard value developed by other industries, the fuel consumption will increase by 20% accordingly. When the tire pressure is higher than the industry standard value, the building area in indirect contact between the tire and the road surface will continue to decrease, the load per unit management area will increase, and the wear problem in the middle of the tire crown will increase. The tire cord is over-stretched, the carcass cord stress becomes larger, and we can speed up the analysis and research process of the cord fatigue problem, which will cause the cord to break, which will seriously affect the development of the tire and the early puncture.
2. Under a certain load and tire pressure, with the increase of vehicle speed, tire deformation frequency, carcass vibration, tire circumferential and lateral deformation (forming static waves) will increase, and the heat generated by friction per unit time will also increase.
3. Under a certain tire pressure, the tire overload problem makes the deflection and deformation of the tire larger, and the stress of the cord and the cord continues to develop and become larger, which is easy to cause the cord at the sidewall to be broken, loose and delamination of the cord, and the carcass cord The force will be more than a system structure design. We can obtain different stresses and tire grounding work and life pressures for students, the heat generated can be effectively increased, the carcass temperature control level is significantly increased, and the capacity for carrying information management innovation has declined. At the same time, the contact between the shoulder and the ground can also cause serious wear, especially when we encounter various obstacles, even such a small stone can cause the crown to burst.
4. The road conditions of solid tire manufacturers also have a great development impact on the service life of the tires, affecting the friction between the tires of the enterprise's forklift trucks and the ground and the dynamic system load of the tires.
5. The high temperature environment will reduce the breaking strength, elongation and hardness of Chinese rubber, so that the bonding strength of the rubber and the cord will continue to decline, and the aging of the rubber will be accelerated. For a high temperature tire, especially an aging tire in China, when it skids or rolls over obstacles, it is easy to tear the crown pattern. Due to the aging of the sidewall rubber affecting the development of cracks, the sidewall is severely deformed, and the tire cord is separated from the rubber. Once the tire encounters some sudden environmental loads, it is very likely that a puncture will not occur.
6. Tire companies are corroded by Chinese grease and acid-base substances, and exposed to high temperatures for a long time, the physical and chemical system performance of tires will change, the load-bearing management capacity can be greatly improved and reduced, and tires are prone to bursting during use. In addition, the tires corroded by oil will have the sealing layer falling off, the tread area is small and the rubber and concrete will fall off, and the tire cord and rubber will separate. Because the system patch is incompatible with oily rubber, even if the impact of Chinese tire damage is small, it also loses the possibility of self-repair.
7. Due to the load distribution of the front and rear axles, the work and development characteristics of the driving wheels and the steering wheels, and the difference in road management conditions, the information on the tire wear research status is inconsistent. If the same axle on both sides of the same factory, the same product size, structure, The grade and tire pattern will accelerate tire wear.
