Embodiment Construction

[0031] figure 1The fixing point B shown in includes two systems 1, 1' of identical construction for fixing a rail S formed in conventional form on a solid base U formed, for example, by concrete sleepers or concrete slabs. The systems 1 , 1 ′ are arranged on the longitudinal sides of the track S in each case. The rail S is part of a rail for a rail vehicle, not shown further, and has a rail foot F, a web lying thereon and a rail head supported by the web, on the free surface of which the rail vehicle is formed. The running surface of the wheel.

[0032] The systems 1 , 1 ′ each comprise a guide plate 2 , 2 ′, on which a spring member 3 , 3 ′ formed as a conventional W-shaped tensioning clip respectively sits. The spring parts 3, 3' are respectively tensioned relative to the base U by a tensioning part 4, 4' formed as a conventional sleeper bolt, which is inserted through the respective guide plate 2, 2' and extends from its upper side to Its underside passes through and is ...

Abstract

The invention relates to a system and to an intermediate element for a system (1, 1') for fixing a rail (S) for a rail vehicle to a base (U). The intermediate element (12, 12') is provided to be arranged between an end section (7, 8) of a spring element (3, 3') and the rail (S), such that the spring element (4, 4') transmits a holding-down force (N, N') to the rail (S) via the intermediate element (12, 12'). The intermediate element (12, 12') has a supporting surface (14), on which the end section (7, 8) of the spring element (3, 3') lies during use, and a standing surface (22), with which the intermediate element (12, 12') is seated on the rail (S) during use. According to the invention, the intermediate element (12, 12') is designed to be resiliently compliant in an active direction (W) directed from the supporting surface (14) toward the standing surface (22). As a result of the installation of an intermediate element (12, 12') according to the invention in a rail fixing system, the risk of shortening the service life of the spring element (3, 3') which is used to hold down the rail in the system, as a result of periodic movements that occur, is minimized.

Description

technical field [0001] The invention relates to an intermediate part of a system for securing a rail of a rail vehicle on a foundation. The intermediate part is here intended to be arranged between the end section of the spring part and the rail of the rail vehicle, so that in use the spring part transmits the downward force via the intermediate part to the rail. For this purpose, the intermediate part has an upper bearing surface, on which the end section of the spring element rests in use, and a lower bearing surface, on which the intermediate part rests on the rail via the lower bearing surface, in use. [0002] The invention likewise relates to a system for fastening rails of a rail vehicle on a foundation, which system is equipped with such an intermediate part. Background technique [0003] Intermediate components and systems of this type are known, for example, from DE 20 2007 018 500 U1. In this known system, a so-called "tensioning clip" is used as the spring part...
