BOLTLESS RAIL FASTENING AND UNDER-RAIL PLATE OF BOLTLESS RAIL FASTENING

摘要

FIELD: construction.;SUBSTANCE: hook-shaped brackets are connected with subterminal projections by reinforcing ribs in boltless rail fastening on the rail plate from side of elevated part. In this case, the central rib coupled with bearing rib, is designed between the hook-shaped brackets. Short tides are made at the outer sides of the hook-shaped brackets, and transitions from the subterminal projections to hook-shaped brackets from side of the lowest part are made with gradual increase of height, passing into long tides of metal on the outer sides of brackets. Invention also relates to the rail plate of the indicated boltless rail fastening.;EFFECT: optimisation of the rail plate design with reduction of its weight while maintaining the strength properties and reliability of rail fastening.;7 cl, 7 dwg
