AI Technical Summary
Technical Problem
Existing rail fastening linings suffer from instability and reduced operational reliability due to limited contact areas and stress concentrations, leading to decreased service life.
Method used
A rail fastening unit lining with a U-shaped groove and rounded projections that connect with the side stop, ensuring a larger contact area and uniform load distribution, eliminating stress concentrations and facilitating smoother load transfer.
Benefits of technology
Enhances the stability and reliability of the rail fastening unit under multidirectional loads, increasing the service life of both the lining and the fastening assembly by distributing loads uniformly and preventing component deterioration.

Abstract
The utility model relates to the field of railway track superstructure, namely to the design of a lining used in rail fastenings on a switchless track section. The technical result of the claimed utility model is to ensure more stable and reliable operation of the lining when bearing multidirectional external loads, increasing the service life of both the lining itself and the rail fastening assembly. The lining is a rectangular plate having a U-shaped groove formed along its short side with projections on the lateral sides of said groove. Moreover, the U-shaped groove and the projections on the lateral sides of said groove of the lining are configured to connect, respectively, with a projection and recesses on the lower surface of the lateral rail fastening stop. Moreover, the U-shaped groove of the lining and the projection on the lower surface of the lateral stop are made with roundings. 5 c.p. fils, 4 figs., 1 pr.
