ANCHOR RAIL FASTENING, SUB-TERMINAL PAD AND SHOCK-ABSORBING UNDER-RAIL GASKET OF ANCHOR RAIL FASTENING (VERSIONS) Russian patent published in 2019 - IPC E01B9/30 E01B9/38 E01B9/48 

FIELD: railways.

SUBSTANCE: invention relates to anchor rail fastening. Anchor rail fastening comprises an anchor with downwards shanks and a middle part integrating two anchor heads, each of which has two spaced apart along the rail bracket, shock-absorbing under-rail gasket with possibility of location between anchor heads, two spring terminals, put on anchor heads and configured to interact with end whiskers through tension regulator with corresponding brackets of anchor head, with the possibility of pressing the rail with the straight-section rail part of the terminals to the under-rail base through the track-mounted insulating spacer and with the possibility of resting with the jack-off turns of terminals on the sub-terminal pad. Sub-terminal pad consists of at least one element, and its total thickness depends on thickness of shock-absorbing underlay gasket to ensure required force of rail pressing against under-rail base so that with reduction of thickness N of shock-absorbing underlay gasket, total thickness T of sub-terminal pad is increased by value of not less than 14–N millimeters, at that, geometrical parameters of terminals do not change. Invention also relates to shock-absorbing gasket of anchor rail fastening, as well as versions of making sub-terminal pad of anchor rail fastening.

EFFECT: as a result, reliable operation of anchor rail fastening is provided at reduced thickness of shock-absorbing under-rail gasket with provision of unified terminals and sleeper.
