How to cure the hottest tractor by eating tires

How to cure the tractor "eating tires"

tire overload, increased slip rate, and accelerated tire wear. At this time, if the pressure of the tires on both sides is different and the difference is large, the wear of the tires with low pressure will intensify, and the "eat" tires do not consider how to use them; 2. It's not fast to undertake high-end R & D and OEM of enterprises

prevention and treatment: when the working temperature of the low-temperature thermostat is low, the air pressure of the tire should meet the requirements, which can be slightly lower in hot seasons. Generally, the lower limit of the specified value is taken. If the tire pressure is too high, the ply will be stretched too much, causing excessive fatigue or fracture; The tire pressure is too low, and the ply is excessively folded and deformed, which is easy to cause the separation of the rubber layer and the ply, and accelerate the aging and wear of the rubber layer. Therefore, do not overload the tractor for a long time to reduce the sliding wear of tires

2 The tractor trailer towing tripod is not isosceles

according to the measurement, when the unequal waist difference of the trailer tripod is 60mm, the service life of the large tire on the short waist side will be shortened by 1/2, and the trailer tire on this side will also aggravate the wear

prevention and treatment method: measure the distance from the center point of the traction pin hole of the tripod to the center of the landing point of the two front wheels of the trailer, and the two distances should be equal. If not, find out the cause and eliminate it. If necessary, remake an isosceles tripod

3. The distance between the front and rear axles on the left and right sides of the tractor is different

the front and rear wheel spacings on both sides are unequal, which will cause abnormal wear of the remaining three tires except the front wheel on the side with short wheel base

prevention and treatment method: check the wheelbase of the front and rear wheels on both sides by aligning the two front wheels and comparing the two shortest distances of the outer edges of the front and rear wheel rims on both sides. If not, find out the reason. Generally, it is caused by the bending and deformation of the steering knuckle support, steering knuckle shaft, front wheel shaft or large axle. It can be removed and corrected or replaced with new parts to restore the equal wheelbase of the front and rear wheels on both sides. Domestic high nickel 3-yuan materials have just started

4. The resonance of the unit accelerates the wear of large tires

if there are no problems with the above three items, but the abnormal phenomenon of abnormal wear of the right large tire is that the unit resonance is making trouble. At this time, as long as the operator changes his habitual throttle position and doesn't always put the throttle on the speed that can cause the resonance of the unit, Owens Corning announced as early as 4 or 5 years ago that the production capacity would not be increased by the end of 2015, and the problem of "eating tires" of large tires will be cured
