Abstract (en)

[origin: WO9858126A1] The invention relates to an arrangement for insulating and damping rails for trackbound vehicles. Damping is imparted through interaction partly through contact between the rail (20) and a central rail foot spreader (1) on each foundation (3), partly through the damping of vertical accelerations via pre-tensioned sleeper clips (4) acting symmetrically in the y-axis, and partly through direct contact between the rail and the foundation (20, 3) - contact damping. Said foundation (3) in the unloaded condition exhibits contact symmetrically in pairs about the y-axis with the rail (20) via the pads (5) furthest away from the y-axis exhibiting on or symmetrically about the y-axis existing sleeper clips (4) in contact with the central part (1) permanently pre-tensioned to the foundations and exhibiting said central part (1) suitably tightened to the rail foot via rail foot spreader clips (2).
