1. Long-term over-loading of tractor tire overload, slip rate increases, accelerated tire wear. At this time, if the pressure of the tires on both sides is different and there is a large difference between them, the wear of tires with low air pressure will increase, and the tires that eat tires will be particularly fast. Prevention methods: tire pressure should meet the regulations, the hot season may be slightly lower, as the lower limit of the specified value. If the tire pressure is too high, the ply will be excessively stretched to cause excessive fatigue or breakage; the tire pressure is too low, and the ply is excessively wrinkled and deformed, which can easily cause the rubber layer to separate from the ply and accelerate the aging and wear of the rubber layer. Therefore, do not overload the tractor for a long period of time to reduce tire slip wear. 2. Trailer traction tripod for trailers hauled by tractors According to the survey, when the trailer tripod is not equal to waist difference of 60mm, a large tire with a short-shoulder side will shorten the service life of 1/2, and the trailer tire on the side will also be Increase wear and tear. Control method: Measure the distance from the center point of the tripod pin hole of the tripod to the center of the two front wheels of the trailer. These two distances should be equal. If you do not wait, you must find out the reason and exclude it. If necessary, recreate an isosceles tripod. 3. The front and rear wheels of the tractor on the left and right sides of the tractor have unequal wheelbases on both sides of the front and rear wheels. Besides the front wheel on the side of the short wheelbase, the rest of the three tires will cause septum wear. Control methods: Check the wheelbase of the front and rear wheels on both sides by correcting the front wheels and compare the two shortest distances on the outer edges of the front and rear wheels. If not, you should find out the reason. Usually caused by the bending deformation of the knuckle bracket, knuckle shaft, front axle or large axle, it can be removed to correct or replace the new one to restore the same wheelbase of the front and rear wheels on both sides. 4. Unit resonance accelerates large tire wear If none of the above three problems are found, but the right tire has an abnormal phenomenon of septum malformation wear, it is the crew resonance. At this time, the driver only needs to change the position of the accelerator, and do not put the throttle on the speed that can cause the unit to resonate. The big tires will be cured if they catch fetuses.
