在拖拉机运输机组的作业成本中,轮胎约占10%～20%,有的甚至更高。因此,有必要搞清轮胎损坏的常见形式及原因,以便在使用中采取改善措施,延长轮胎的使用寿命。 (1)胎面单边磨损原因:前轮前束过大,驱动轮和挂车轮长期行驶于拱形路面。应及时左右对调轮胎,校正前轮前束值。 (2)胎面花纹磨损严重原因:多为轮胎长期充气不足。反之,若充气过高,会使胎面中部磨损严重。因此,轮胎气压不要过高或过低。另外,拖拉机长期超载也是轮胎磨损
In the tractor transport unit operating costs, the tire accounts for about 10% to 20%, and some even higher. Therefore, it is necessary to find out the common forms and causes of tire damage so that improvement measures can be taken to prolong the service life of the tire. (1) unilateral tread wear reasons: the front beam is too large, long-term drive wheel and trailer wheel in the arched pavement. Should be about the transfer of tires, correction of the value of the front wheel before. (2) Tread pattern wear serious reasons: mostly long-term inflated tires. Conversely, if the inflation is too high, it will make the central tread wear seriously. Therefore, the tire pressure should not be too high or too low. In addition, long-term tractor overload is tire wear
