Definitions
- the invention relates to a guide plate for laterally guiding a rail in a rail fastening point formed on a threshold.
- the guide plate has an upper side on which a support surface for supporting a spring element is formed. Furthermore, such a guide plate has an underside, by means of which the guide plate is supported on the threshold in use. On an end face of a support section of the guide plate there is also a support surface, via which the guide plate is supported in use on a shoulder provided on the threshold.
- the guide plate also has a guide section that extends in the longitudinal direction of the guide plate
- Such guide plates are known in various configurations, for example from DE 102 54 679 B4. In addition, reference is made to guide plates according to DE 34 23 997 A1, DE 20 2011 104 743 U1 or US 6 305 613 B1.
- the rail fastening point in which the guide plate is inserted, is usually erected on the top of a cuboid-shaped threshold, on which a support surface for the rail is provided, which is laterally delimited by a support shoulder in the longitudinal direction of the threshold.
- Rail fastening points in which rails for rail vehicles are fastened on a threshold, and the components required for their manufacture are in use millions of times in practice. It is in one
- Guide plates not only ensure that the rail maintains its correct position in the track when a rail vehicle drives over it, but also serve as a support for each spring element that is braced against the threshold that supports the rail and that has an elastic hold-down force on that of the respective rail Associated guide plate
- the support shoulders are provided on the threshold.
- the respective guide plate is supported against one of these shoulders on its side opposite the rail.
- the exact positioning and support of the guide plate can be supported by the fact that on the underside of the guide plate, typically in the area of the
- Guide plate an angular guide section is formed in the side view, which engages in a groove formed in the threshold and extending in the width direction of the threshold.
- Guide plates shaped in this way are referred to in technical terms as “angle guide plates”.
- the sleepers on which the respective rail is fixed and which as such are part of the respective rail fastening point usually carry two rails running parallel to one another, which together form a track on which a rail vehicle rolls with its rail wheels. In this way, the sleepers form the true-to-track, parallel course of the rails of a track and distribute them when passing over the rails Rail vehicle loads on the substructure supporting the sleepers. In conventional track systems, this substructure is usually designed as a ballast bed, on or in which the sleepers are loose.
- the sleepers are typically moved 10 - 50 cm laterally compared to their proper alignment.
- the rails are twisted in the
- Shaped sleepers so-called “Y steel sleepers”, which ensure a particularly high resistance to lateral deformation of the track, reduce the tendency to buckle. Also, by increasing the
- Threshold edges are increased.
- the task is to design a guide plate so that when used in a rail fastening point, it counteracts twisting of the rail with optimum resistance and the associated risk of warping of the track occurring at high outside temperatures.
- a rail fastening point should be specified, in which the rail is twisted in the same way and thus at high

- Front face having guide surface is formed in the region of the end sections of the guide surface in the manner of lugs, projecting locking projections which, when using a guide plate according to the invention, are formed in one
- the locking projections thus prevent the end portions of the guide surface of the guide plate when the guide plate is assembled
- Twisted rail ensure that the guide plate is loaded evenly and opposes a deformation of the rail with a high degree of rigidity, so that a high resistance to twisting of the rail is consequently stronger
- the rail fastening point according to the invention ensures that the rail is also supported on the threshold between the locking projections over a long distance without the intermediate material of the guide plate.
- the arrangement is spaced as far apart as possible
- a particularly practical embodiment of the invention provides that the locking projections border on the corner region assigned to them, in which the guide surfaces each have one
- the locking projections each extend at most over the width of the end section of the guide surface assigned to them, so that a sufficiently large distance between the locking projections remains free.
