APPARATUS FOR REDUCING FRICTION NOISE FROM FLANGED WHEEL ENTERING CURVED RAIL

摘要

PURPOSE: bending track is entered to minimize noise by cutting off the shock and vibration flange oil inlet and guide rail that generate between transfer from rolling stock for reducing frictional noise. ;CONSTITUTION: including outer rail (21), interior guide rail (22), bumper member and interior fence fixed cell for reducing frictional noise to enter from rolling stock with warp rail. Outer rail includes support unit (21a) and a rail body unit (21b). Support unit supports are to roadbed and sleeper. This rail body unit stretches out the support unit at top. The longitudinal direction setting outer rail of internal rail and the contact surface with flange. Buffer element is set to the friction noise between outwardly and inwardly track between interior sliding rail, to cut off flange oil inlet and Hp contacts surface. The fixed internal rail of interior guide rail fixed cell and side rail deflect. ;The 2012 of copyright KIPO submissions
