Abstract

A rail fastening system for fastening a rail on a subsurface, preferably a ballastless track, comprises at least one retaining element for mounting the rail on the subsurface. The retaining element has an angle guide plate that, in the assembled state, is configured to divert transverse forces from the rail into the subsurface and a shoulder part that, in the assembled state, is configured to butt together with the angle guide plate and to lie in a recess of the subsurface in a positive-locking manner.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A rail fastening system for fastening a rail on a subsurface, comprising
 a retaining element for mounting the rail on the subsurface, wherein the retaining element has
 an angle guide plate that, in an assembled state, is configured to divert transverse forces from the rail into the subsurface and 
 a shoulder part that, in the assembled state, is configured to butt together with the angle guide plate and to lie in a recess of the subsurface in a positive-locking manner. 
   
     
     
         2 . The rail fastening system according to  claim 1 , wherein the subsurface is a ballastless track. 
     
     
         3 . The rail fastening system according to  claim 1 , wherein the shoulder part has a recess that is configured and dimensioned for flush support of the angle guide plate. 
     
     
         4 . The rail fastening system according to  claim 1 , wherein the shoulder part has a recess that is configured and dimensioned for flush support of a projection on an underside of the angle guide plate. 
     
     
         5 . The rail fastening system according to  claim 1 , wherein the shoulder part has
 an underside that is configured to rest on a bottom of the recess of the subsurface, and   an outer side wall, which extends obliquely outwards from the underside at an angle and is configured to rest against a corresponding wall of the recess.   
     
     
         6 . The rail fastening system according to  claim 5 , wherein the angle between the underside and the outer side wall is greater than 90 degrees. 
     
     
         7 . The rail fastening system according to  claim 5 , wherein the angle between the underside and the outer side wall is between 120±15 degrees. 
     
     
         8 . The rail fastening system according to  claim 5 , wherein the shoulder part further has an inner side wall which extends obliquely inwards from the underside at an angle, such that the shoulder part has a trapezoidal cross-section. 
     
     
         9 . The rail fastening system according to  claim 1 , further comprising a spacer plate for mounting between the rail and the subsurface. 
     
     
         10 . The rail fastening system according to  claim 1 , further comprising
 a rail bearing plate that is configured to hold the rail, wherein, in the assembled state,
 the rail is in contact with the rail bearing plate, 
 the rail is fastened on the rail bearing plate by a rail holder, and 
 the angle guide plate butts together with an end face of the rail bearing plate. 
   
     
     
         11 . The rail fastening system according to  claim 10 , further comprising
 at least one intermediate plate made of a flexible material,   wherein, in the assembled state, the intermediate plate is arranged between the subsurface and the rail bearing plate.   
     
     
         12 . The rail fastening system according to  claim 11 , wherein the flexible material has a dynamic stiffness of 200 kN/mm or less. 
     
     
         13 . The rail fastening system according to  claim 1 , wherein the retaining element has a tensioning clamp that is configured to press the rail with a defined force onto the subsurface. 
     
     
         14 . The rail fastening system according to  claim 1 , wherein the retaining element has a tensioning clamp that is configured to press the rail with a defined force onto the subsurface via the angled guide plate. 
     
     
         15 . The rail fastening system according to  claim 14 , wherein the angle guide plate supports and determines a position and location of the tensioning clamp. 
     
     
         16 . The rail fastening system according to  claim 1 ,
 wherein the retaining element has a plug and a screw-shaped fastening element,   the screw-shaped fastening element being anchored in the subsurface by the plug.   
     
     
         17 . A railway track with a rail and at least one rail fastening system according to  claim 1 , wherein the rail is mounted on a subsurface by the rail fastening system. 
     
     
         18 . A railway track with a rail, wherein the rail is mounted on a subsurface by two rail fastening systems as in  claim 1  that are opposite each other in a transverse direction. 
     
     
         19 . The railway track as in  claim 17 , wherein the rail is part of a switch.
