SLEEPER WITH FRICTION UNIT FOR DECREASING IRREGULARITY OF TRACK BY MAXIMIZING FRICTIONAL FORCE BETWEEN SLEEPER AND GRAVEL

摘要

PURPOSE: A sleeper for decreasing irregularity of a track is provided to prevent an accident by preventing the distortion of a rail by maximizing frictional force between a sleeper and gravel, to prevent the maintenance expenses for a track and to improve the speed of a train. CONSTITUTION: The sleeper for decreasing irregularity of a track contains rail grooves(1) formed on both upper parts to narrow toward the lower part, and a friction unit(10) formed to increase the frictional force with gravels between sleepers, wherein the friction unit(10) contains a curved surface(11) formed toward the center of the straight sleeper.
