ADD-ON RAIL INSULATING GASKET OF ANCHOR RAIL JOINT Russian patent published in 2014 - IPC E01B9/30 E01B9/48 

FIELD: construction.

SUBSTANCE: invention relates to a superstructure of a railway track and is designed for coupling of the rail with elements of the anchor rail joint. An add-on rail insulating gasket of the anchor rail joint comprises an upper 1 and a lower 2 vertical shelves combined into a single structure, and also an add-on rail shelf 3. The lower 2 and the add-on rail 3 shelves cover the rail foot 8. The add-on rail shelf is made in the form of a separate element coupled with the upper 1 and lower 2 vertical shelves with the possibility of movement in the vertical direction and rotation relative to the axis parallel to the longitudinal axis of the rail symmetry 8. Coupling of the add-on rail shelf with the upper 1 and lower 2 vertical shelf combined into a single structure, is made in the form of a split lock connection. The add-on rail shelf 3 is made with two cantilever ledges 11, ends of which are made in the form of U-shaped spring elements 12. There is a window 13 with a vertical link 14 made with the upper 1 and lower 2 vertical shelves combined into a single structure. U-shaped spring elements 12 are introduced into the window 13 at different sides from the vertical link 14, at the same time height of the window 13 exceeds the thickness of the add-on rail shelf 3.

EFFECT: reduced intensity and uneven wear of an add-on rail insulating pad of an anchor rail joint, and thus its durability increases.
