Embodiment Construction

[0064] exist Figure 9 The fixing point B shown in , where the rail S is fixed to the concrete sleepers forming the base U, consists of a rail fixing system comprising two fastening clips SK1, SK2, two guide Plates FP1, FP2, two fastening bolts SR1, SR2 required for fastening the respective fastening clips SK1, SK2 as fastening means and a spring element formed substantially rectangular in top view, which is shown in all drawings are marked with a "1" regardless of their design shown in the figure.

[0065] One of the fastening clips SK1, SK2, one of the guide plates FP1, FP2 and one of the fastening bolts SR1, SR2 are respectively placed on one of the longitudinal sides L1, L2 of the rail S, while the elastic element 1 is located on the rail S Between the rail foot SF and the base U. Correspondingly, the rail S with its rail foot SF rests on the support surface 2 corresponding to the rail of the spring element 1 , which rests on the base U with its support surface 3 corresp...

Abstract

Elastic element which is intended to be arranged in a fastening point (SB) for a rail (S) for rail vehicles between the rail (S) and the foundation (U) supporting it, wherein the elastic element (1) has a standing surface (2) assigned to the foot (SF) of the rail (S) and a bearing surface (3) assigned to the foundation (U), and wherein the elastic element (1) comprises a basic body (4), which consists of a material which behaves in an elastically flexible manner at least in a loading direction directed towards the standing surface (2), and at least one damping element (D1-D4) which is embeddedinto the elastic material of the basic body (4), wherein the damping element (D1-D4) has at least one contact portion (14, 19, 23, 25), which is assigned to the standing surface (2) and, with the elastic element (1) unloaded, is oriented flush with the standing surface (2) of the elastic element (1) or projects beyond the standing surface (2) of the elastic element (1), and at least two spaced-apart supporting portions (10, 13, 18, 20, 21, 26) assigned to the bearing surface of the elastic element, and wherein the contact portion (14, 19, 23, 25) is arranged in the region (15) spanned by thedamping element (D1-D4) between the supporting portions (10, 13, 18, 20, 21, 26) and is supported in an elastically flexible manner in the manner of a bridge in the loading direction (V).

Description

technical field [0001] The invention relates to an elastic element, which is arranged to be placed between a rail and a base carrying the rail in a fixed point of a rail of a rail vehicle, wherein the elastic element has a bearing surface corresponding to the rail foot and a bearing surface corresponding to the base. The support surface, and wherein the elastic element comprises a base body made of elastically deformable material at least in a load direction oriented relative to the support surface, and at least one damping element embedded in the elastic material of the base body. [0002] Furthermore, the invention relates to a fastening point in which the rail is fastened to the base. [0003] The elastic element according to the invention is in particular a so-called "middle layer" or "middle plate", whose width and length are much greater than its thickness. Background technique [0004] Elastic elements of the type discussed here are usually arranged in track laying b...
