RAIL FISHPLATE WITH SUPPORT FOR RAIL WHEEL FLANGE Russian patent published in 2005 - IPC

FIELD: mechanical engineering.

SUBSTANCE: invention can be used in devices with rolling guides and it is aimed at improving design of rail fishplates. Proposed fishplate with support for wheel flange contains upper and lower heads and neck with holes for bolt joints, and support surfaces or wheel flange. Upper head is provided with step with inclined end face surface, two axial stops and two cavities on support surface of stop. Cavities accommodate pivots with curvilinear surfaces. Rod with trapezium cross section, for instance, isosceles, with said support surfaces for wheel flange and support surface in contact with curvilinear surfaces of pivots is arranged between axial stops. Side surfaces of rod are in contact with inclined surfaces of step and pressure washer of bolt joint.

EFFECT: increased service life of fishplate with support for rail wheel flange, improved operation reliability of rail track.
