RAIL FASTENING Russian patent published in 2015 - IPC E01B9/30 E01B9/38 E01B9/48 

FIELD: construction.

SUBSTANCE: rail fastening includes an under-rail lining made in the form of clamp (1) attached with bolts (5) to under-rail base (2), and lever (7) oriented perpendicular to longitudinal axis of rail (8) and hinged with one end by means of silent block (6) to clamp (1) and having platform (9) for installation of rail (8) on the other end, which is provided with projections (10) restricting rail movement in the direction perpendicular to the track axis. Rail (8) is attached to the under-rail lining with two terminals (11) located on both sides of rail (8). Some ends of terminals (11) are taken under lower surface of the rail installation platform, and the other ends of terminals are supported from upper surface of base of rail (8) by means of hexagonal controls (12) put with eccentricity on those ends. Besides, rail fastening includes two elastic elements (15) located between rail (8) and base of track (2) on both sides of lever (7), and their thickness is chosen considering formation of a gap between base of track (2) and lower surface of lever (7) in the position when force from train wheels acts on rail (8).

EFFECT: durability and high reliability of a rail track.
