Is presented the solution of important sectoral issues to improve traffic safety of rolling stock by reducing lateral wear of wheels and rails heads when changes trucks in curves parts of the route by increasing reliability and durability of the pivot site.
To resolve this task, the paper proposed to the original design decision metered supply of lubricant to the friction surfaces of the parts with wear and tear their contact surfaces. According to the proposed resolution on friction surfaces pivot site are hollow, filled with solid composite lubricant, which in process of deterioration will portions get in contact area.
Theoretical foundations and the equation of adaptive management is present.
