Elastic intermediate layer for rail clamp, has two polymer parts with different shore hardness, where one part has higher shore hardness that covers region where rail fastening unit is arranged and is constructed in angular form

摘要

The layer has an polymer part (1) with shore hardness of 50-65, for absorption of load, and another polymer part (2) with higher shore hardness of 80-90. The thickness of the part (1) is larger than the thickness of the part (2). The part (2) covers a region where a rail fastening unit is arranged. The part (2) is constructed in an angular form and is arranged in one or both sides of the layer.
