Abstract:
1. A bearing for a section of a track having, along the track sections, profile sections which deviate from one another, in the form of a switch point, comprising a plurality of supporting points respectively provided with a base plate ( 10 ) and a rectangular intermediate plate ( 24 , 72 , 116 ) made of an elastic material disposed between the base plate ( 10 , 66 , 68 , 112 , 114 ) and an associated support having a bearing surface ( 34 ), with transverse edges extending in longitudinal direction of the track section and with longitudinal edges extending diagonally to the track section which extend along the longitudinal axis of the intermediate plate, each supporting point having an identical maximum subsidence with respect to each cleared track section or track sections by support by adjusting spring rigidity of the intermediate plate and moment of resistance of the track section supported on the supporting point, characterized therein that the intermediate plate ( 24 , 72 , 116 ) has a first section surrounding the base plate on the edge and supporting it on the bearing surface ( 34 ) and a second section ( 32 ) within the first section spaced from the bearing surface when the base plate is cleared from unloaded or common wheel loads and that the second section has recesses ( 38 , 40 , 42 , 44 , 78 , 80 , 82 , 84 , 122 , 124 ) with a bone-shaped geometry extending the central region of the intermediate plate proceeding from each longitudinal edge symmetrically to the longitudinal axis of the intermediate plate which are limited by a continuous third section ( 34 , 76 ) of the intermediate plate which is spaced from the bearing surface when the base plate is clearing unloaded or common wheel loads.
