The abrasion of wheel rim and rail side are greatly decreased when vehicle passes through curve circuit for wheel rim root.
However, the control of the injection control generally use fixed range of traditional wet type wheel flange lubricating, set time and bend
Mode processed carries out injection lubricating oil, easy tos produce the problem of accidentally spraying, and cannot fully achieve and be carried out in required circuit place
Accurate injection, thus, while lubricating oil largely consumes, wheeling edge wearing is still more serious.
