Abstract
A rail-mounting assembly (S) for fastening a rail (3) to a fixed substrate (5) with an intermediate construction (2) between the rail (3) and the fixed substrate (5) that operatively connects the rail (3) to the fixed substrate (5) in an elastic manner, and the intermediate construction (2) comprises only a elastic intermediate layer element (1; 101) that has a variable elasticity distribution across its cross-section (6) in the direction (7A) of its longitudinal extension (8) and/or in the direction (7B) transverse to its longitudinal extension (8).
Claims24
A rail-mounting assembly for fastening a rail to a fixed substrate including polyvalent sleepers, the assembly being between the rail and the fixed substrate operatively connected to the fixed substrate in an elastic manner, and comprising
- a single elastic intermediate layer element having a variable elasticity distribution across its cross-section in the direction of its longitudinal extension and/or in the direction transverse to its longitudinal extension;
- and
- a hard intermediate element having a trapezoidal part and lying between the elastic intermediate layer element and the fixed substrate.
A rail-mounting assembly for fastening a rail to a fixed substrate including polyvalent sleepers, the assembly being between the rail and the fixed substrate operatively connected to the fixed substrate in an elastic manner, and comprising
- a single elastic intermediate layer element having a variable elasticity distribution across its cross-section in the direction of its longitudinal extension and/or in the direction transverse to its longitudinal extension;
- and
