What are the reasons for the abnormal wear of the heavy duty forklift tires?
1. Under certain load and tire pressure, the vehicle speed increases, the deformation frequency of the tire, the vibration of the carcass and the distortion of the circumference and lateral direction of the tire (formation of static waves) increase, and the heat generated by friction per unit time increases. The performance of the tires is degraded, and even ply cracking and tread peeling occur, which accelerates the wear and damage of the tire.
Second, under certain load and driving conditions, the tire of the forklift has a suitable tire pressure. When the tire pressure is lower than the standard value, the radial deformation of the tire increases, and the two sides are excessively deflected, so that both sides of the crown Grounding, the inner wall of the sidewall is pressed, the outer wall of the sidewall is pulled, and the cord in the tire body is subjected to large deformation and alternating stress. The extension Ang Lide forklift parts indicate periodic compression deformation, which will damage the fatigue of the rewinding cord, so that the relative slip between the ply of the tire and the tire and the ground increases, the heat generated by the friction increases, and the temperature of the tire rises sharply. The tensile strength of the rubber is lowered, the cord is loosely and partially delaminated, and a puncture occurs when an obstacle is encountered.
Third, under a certain tire pressure, the tire overload increases its flexural deformation, and the stress of the curtain and the cord increases, which easily causes the cord of the sidewall to be broken, loose and the delamination of the cord, and the force of the carcass cord The heat generated by the design allowable stress and the grounding pressure of the tire will increase, the temperature of the carcass will increase, and the load bearing capacity will decrease. At the same time, wear is caused by the contact between the shoulder and the ground, especially in the case of obstacles, even a small stone will cause the crown to blast.
Fourth, the road conditions have a great impact on the service life of the tire, which affects the friction between the tire and the ground and the dynamic load on the tire.
