Intermediate Element and System for Fixing a Rail for a Rail Vehicle Onto a Foundation

Abstract

A system and an intermediate element for a system for fixing a rail for a rail vehicle onto a foundation. The intermediate element is arranged between an end section of a spring element and the rail such that the spring element exerts a retaining force on the rail by means of the intermediate element. The intermediate element has a supporting surface, on which the end section of the spring element rests during use, and a contact surface, with which the intermediate element sits on the rail during use. The intermediate element is elastically resilient in an active direction from the supporting surface towards the contact surface.

The intermediate element according to  claim 6 , wherein the dimensionally stable sections are connected by means of a support made from a material which has less elasticity than the elastic element, and wherein the dimensionally stable sections and the support define a retainer on an upper side, underside and long side thereof, in which the elastic element sits. 
     
     
         8 . The intermediate element according to  claim 7 , wherein the dimensionally stable sections and the support are manufactured as a single piece. 
     
     
         9 . The intermediate element according to  claim 5 , wherein the respective dimensionally stable section is made from a synthetic material. 
     
     
         10 . The intermediate element according to  claim 5 , wherein the elastic element is firmly bonded to the respective dimensionally stable section. 
     
     
         11 . The intermediate element according to  claim 10 , wherein the elastic element is injection moulded onto the respective dimensionally stable section. 
     
     
         12 . The intermediate element according to  claim 1 , wherein the intermediate element is configured in the shape of an elongated rectangle. 
     
     
         13 . The intermediate element according to  claim 1 , wherein the intermediate element has a long side in which a recess is formed, with which a section of the spring element engages during use, the at least one end section of which is braced on the supporting surface of the intermediate element during use. 
     
     
         14 . The intermediate element according to  claim 1 , wherein moulded parts are configured on the supporting surface, against which the assigned end section of the spring element is braced during use. 
     
     
         15 . A system for fixing a rail for a rail vehicle to a foundation, wherein the rail has a rail foot with which it is supported on the base comprising:
 a spring element braced against the foundation by means of a tensioning element, which has at least one spring arm with an end section configured on the free end thereof, and   an intermediate element configured according to  claim 1 , the contact surface of which rests on the foot of the rail and on the supporting surface of which the end section of the spring arm of the spring element rests.   
     
     
         16 . The intermediate element according to  claim 1 , wherein the intermediate element has a dimensionally stable section on a free upper side of which the supporting surface is configured.
