SHOCKLESS RAIL JOINT Russian patent published in 2017 - IPC E01B11/40 

FIELD: construction.

SUBSTANCE: shockless rail joint comprises mutually superimposed and enlarged in cross-section the upper and the lower parts, fastened together with bolts to move longitudinally. The lower part from the bottom reproduces the shape of the sole of the receiving rail. In the top at the level of the lower line of the lower height of the rail head the lower part has a support area, there beginning of which is made with a small sphericity to the length of the longest gap between rails. The upper part in the top follows the shape of the rail head and throughout its height has a width equal to the width of the rail head bottom. On the bottom line of the height of the rail head the top portion is split into two halves, forming downward clamp-like shape and flat longitudinal bearing area. The gap between rails is spaced into two gaps which do not match in vertical direction, the first one upwards, towards the end face of the receiving rail head, the second one downwards to the toe of the passing rail.

EFFECT: possibility for joint design simplification and increase of its working section.
