Due to the very harsh environment of the loading truck, the consumption of tires will also increase, and the cost accounts for 10% to 20% of the entire transportation cost. The consumption of mining truck tires is directly related to the vehicle operating cost and transportation efficiency. By analyzing the main factors affecting mining truck tires in detail, we propose correct use and maintenance measures to extend the overall service life of mining truck tires.
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. In general, the faster the vehicle travels, the greater the ground impact load the tire will bear. Unit Over time, the more the tread deforms, the faster the internal temperature of the tire rises. In the high temperature environment of mining truck tires, the rubber cohesion decreases, resulting in delamination, blasting, and peeling of the tire cord fatigue.
Air pressure: For the tire design of the loading vehicle, the inflation method is used as the basis. Under the condition of ensuring the tire inflation pressure, a deformation can be given to meet the floating, load-bearing and traction force required by the vehicle during the moving process, which determines the inflation pressure for mining. The influence of tire usage. If the inflation pressure is too high, the tension of the tire cord will increase, and the tire flexural performance will also decrease when the vehicle is driven on a road with relatively poor road quality.
If the inflation pressure is small, high stress will be generated between the plies, which will also cause the side bending deformation of the mining truck tire, the slippage generated by the tread, and the inward depression, and even increase the load on the crown shoulder of the tire. The middle is arched upwards to speed up the wear of the shoulders of the tires.
