FIELD: transport.SUBSTANCE: invention relates to rolling-stock and lift-and-carry transfer mechanisms moving along rails. Wheel-rail system includes wheel having at least one collar (flange) with ring groove filled with solid lubricant. Edges of the groove are contacting with side surface of rail head. On edge butt joint of rails, place of intersection of butt and side surfaces of head has profiled surface the length of which exceeds width of ring groove. Transverse displacement of rails does not exceed distance from intersection of the mentioned surface with butt end of one rail to side surface of the other rail.EFFECT: increased durability of wheel-rail system.2 dwg |
