RAIL BOND Russian patent published in 1994 - IPC

FIELD: railway transport. SUBSTANCE: bond has metal current conductor 1 made in form of horizontal section with ends twisted to radius changing into oppositely oriented sections of branches of reciprocal spiral, shaped bushings 2 fitted on ends and shells 3 press-fitted in holes of weds of rails 4 and 5 arranged at both sides from fish-plate 6. To protect rail from lateral vibroexcitations coaxial cylindrical dampers 7 are fitted on twisted sections of current conductor. To strengthen termination of current conductor ends and to stabilize contact resistance of bond, end sections of bushing cantilevers at place of termination of current conductor ends are plastically upset by cross half-ring grooves 8. EFFECT: enhanced operation reliability. 3 cl, 2 dwg
