FIELD: railway transport. ^ SUBSTANCE: proposed wheelset of rail vehicle contains axle boxes in which hollow axle with piston is installed carrying wheels with flanges and provided with channels to pass lubricant to wheel flanges. Piston is in contact with rod through its end face surfaces. Additional pistons spring-loaded relative to axle box covers are installed in axle box space on ends of said rods. Additional pistons are provided with check valves on end face surface. Covers have holes in lower part with fitted in pipelines whose ends come in contact with surfaces of wheelset flanges through air gap. Ends of pipelines and axes of holes of axle box covers are displaced relative to each other in height. ^ EFFECT: increased service life of wheelsets. ^ 2 dwg |
