Title: RAIL FASTENING CLIP
Abstract:
The utility model relates to railway track structure, and more particularly to designs of spring clips which can be used in rail fastenings for fastening rails to rail pads which are fixed to a foundation such as sleepers. The present rail fastening clip is configured as a single piece with mirror symmetry about its longitudinal axis L, and comprises a straight portion that lies on the rail, said straight portion transitioning at two opposite ends through bend radii into upwardly arched and outwardly inclined lateral portions of the clip, the continuation of which is comprised of portions which are curved in plan view and which transition into free peripheral portions, the ends of which are oriented toward the straight portion that lies on the rail. What is novel is that the peripheral free portions of the clip are straight and are situated below the level N of the maximum height of the lateral portions of the clip, and the clip, in plan view, smoothly widens in the direction of the portion that lies on the rail via the lateral portions. The technical result is an increase in the reliability of the spring clip, which provides reliable clamping of the foot of a rail to a rail pad.
