INTERMEDIATE RAIL FASTENING Russian patent published in 2005 - IPC

FIELD: railway transport; permanent way.

SUBSTANCE: invention is designed for fastening rails to reinforced concrete ties. Proposed intermediate rail fastening contains anchor fixed by lower part in under-rail support and elastic clamp secured on upper part and projecting over under-rail support. Clamp is essentially torsional spring containing one or several straight-line extended section whose axes in premounting state are arranged relative to each other either at acute angle or parallel. One of free ends of clamp, being extension of straight-line extended section, is lever made for thrusting against rail foot and deflecting from vertical axis of anchor within the limits of acute angle when finally mounted. Other free end of clamp is made for fastening in anchor. Invention proposed intermediate rail fastening of simple design providing stability of design position of rails on under-rail supports in process of operation whose resilience in vertical direction is sufficient to level track (in height) up to 20 mm and more and required pressure of rails to ties in summer and winter, reduced number of parts.

EFFECT: improved reliability in operation.
