Analysis of the wear of mine truck tire

Because the environment of mining vehicles is very harsh, the consumption of tires will also be large. The cost accounts for 10% to 20% of the total transportation cost. The consumption of mining vehicle tires is directly related to the operating cost of the vehicle. Transportation efficiency. We are able to extend the overall service life of mining vehicle tires through detailed analysis of the main factors affecting mining vehicle tires and propose correct use and maintenance measures.
Driving state: If the driving speed is too fast, compared with the normal driving state, the tire temperature and speed will also increase, which can speed up the overall wear rate. Generally, the faster the vehicle travels, the greater the ground impact load the tire has to bear. The more times the tread is deformed per unit time, the increase in the internal temperature of the tire will be accelerated. In addition, in the high temperature environment of mining vehicle tires, the rubber adhesion will also decrease, which will cause delamination, blasting, and peeling of the tire cord fatigue.
Air pressure: The design of tires for mining vehicles is mainly based on the expansion method. Under the condition of ensuring the inflation pressure of the tires, a deformation can be given to meet the floating, bearing and traction forces required by the vehicle during the movement, so this determines the inflation The influence of pressure on the usage of mining truck tires. If the inflation pressure is too high, the tire cord tension will increase, and the vehicle will drive on a road with relatively poor road quality, and the tire’s flexural resistance will also decrease.
If the inflation pressure is small, high stress will be generated between the plies, which will also cause the side curvature of the tire of the mining vehicle, the slippage caused by the tread, and the inward depression, and even the crown and shoulders of the tire. As the load rises, the middle part arches upwards, accelerating the wear of the tire shoulders.
