Analysis of eight causes of abnormal wear of electric pallet truck tires

Analyze the eight causes of abnormal wear of electric pallet truck tires

①Under certain load and driving conditions, the tires of the pallet truck have a suitable tire pressure. When the tire pressure is lower than the standard value When driving, the radial deformation of the tire increases, and excessive deflection occurs on both sides, so that both sides of the crown are grounded, the inner wall of the sidewall is compressed, the outer wall of the sidewall is pulled, and the cords in the carcass produce large deformation and alternating stress. Periodic compression deformation will speed up the fatigue damage of the cord, increase the relative slip between the ply of the tire and the tire and the ground, increase the heat generated by friction, increase the temperature of the tire sharply, and reduce the tensile strength of the rubber. , the cord is loose and partially delaminated, and a tire blowout occurs when an obstacle is impacted. The uneven pressure of the tread causes serious wear on the shoulder part, resulting in a 'bridge effectThe grooves of the tread pattern are easily embedded in the nails and stones of the road, causing mechanical damage. The rolling resistance of the carcass increases and the fuel consumption increases. Tests show that when the tire pressure is lower than the standard value by 20%-25%, the fuel consumption will increase by 20%. When the tire pressure is higher than the standard value, the center of the tire crown is grounded, the contact area between the tire and the road surface is reduced, the load per unit area increases, and the wear of the center of the tire crown increases. The cord of the tire is overstretched, the stress of the carcass cord increases, and the fatigue process of the cord is accelerated, causing the cord to break, resulting in an early tire blowout.

②Under a certain load and tire pressure, when the vehicle speed increases, the deformation frequency of the tire, the vibration of the carcass, and the circumferential and lateral twisting deformation of the tire (forming static waves) increase. The heat generated by friction increases, the working performance of the tire decreases, and even the ply rupture and tread peeling occur, which accelerates the wear and damage of the tire.

③Under a certain tire pressure, the overload of the tire will increase the deflection and deformation, and the stress of the cord and cord will increase, which is easy to cause the cord at the sidewall to break, loosen and delaminate the cord. The stress on the body cord will exceed the design allowable stress and tire ground pressure, the heat generated increases, the carcass temperature increases, and the load-bearing capacity decreases. At the same time, due to the wear of the tire shoulder and the ground, especially when encountering obstacles, even a small stone will cause the tire crown to burst. Practice has proved that in the case of turning and driving on uneven roads, when the tire load exceeds 20%, its mileage will be shortened by 35%; when it exceeds 50%, it will be shortened by 59%; when it exceeds 1 times, it will be shortened by more than 80%.

④The road condition also has a great influence on the service life of the tire, which affects the friction between the tire and the ground and the dynamic load on the tire.

⑤High temperature will reduce the tensile strength, elongation and hardness of rubber, reduce the adhesion strength between rubber and cord, and also accelerate the aging of rubber. For tires at high temperature, especially those that have been aged, it is easy to tear the crown pattern when it slips or rolls over obstacles. Due to the aging of the sidewall rubber and the cracks and the severe deformation of the sidewall, the carcass layer cords are separated from the rubber. Once the tire encounters a sudden load locally, it is likely to have a puncture.

⑥When the tire is corroded by grease, acid and alkali substances and high temperature for a long time, the physical and chemical properties of the tire will change, the bearing capacity will be greatly reduced, and the tire will be easily punctured during use. In addition, the tire corroded by oil will appear block peeling of the air seal, small area of u200bu200brubber peeling off the tire mouth, and the carcass cord and rubber are separated. Since the patch is not compatible with the oil-containing rubber, the possibility of repair is lost even if the damage to the tire is small.

⑦Due to the different loads distributed by the front and rear axles, different working characteristics of the driving wheels and steering wheels, and different road conditions, the wear conditions of each tire are inconsistent. Tire size, construction, ply and pattern will accelerate tire wear.

⑧In use, if you do not pay attention to reasonable collocation and regular rotation, the tires will bear uneven load, which will also accelerate tire wear.
