RESILIENT CUSHIONING RAIL FASTENING WITH HORIZONTAL ELASTICITY IN THE TRANSVERSE DIRECTION FOR SMALL-RADIUS CURVES

摘要

A resilient cushioning rail fastening consists of a cast iron baseplate (3) on a wooden sleeper (2). The baseplate has through openings which pass through supporting cones on the underside thereof, said supporting cones being fitted into dimensionally corresponding recesses in the sleeper (2). Steel screws (5) pass through the openings, are screwed into plastic dowels (6) incorporated into the sleeper (2), and clamp the rail (1) via two resilient clips (7). The iron baseplate (3) has two flanges (10) and (11). The outer flange (10) is provided with recesses, into which are inserted helical/disc/shaped springs (9) that press the foot of the rail (1) against flange (11). A strictly defined gap (a) is formed. When rolling stock enters a curve, transverse horizontal forces, overcoming the force of the springs (9), displace the foot (1) until the latter rests against the rigid support (10).
