DIESEL LOCOMOTIVE WHEELSET Russian patent published in 2004 - IPC

FIELD: transport engineering; rail vehicles.

SUBSTANCE: proposed wheelset of diesel locomotive contains axle with wheels and flanges, whose necks are arranged in axle boxes interconnected in contact with axial stops installed for movement in housing of axle boxes and their cups and are spring-loaded by compression spring relative to cups. Axial stops and cups are provided with through holes in vertical plane. Axes of holes are arranged so that their paired alignment or misalignment in upper part of said cups or axial stops in lower part is possible only at translational movement of axial stops. Upper holes of cups are connected by pipelines with plastic lubricant storage container where lubricant is kept under excess pressure, and lower holes are provided with check valves and are connected by means of pipelines through air gap with flanges of wheelset.
