FIELD: construction.SUBSTANCE: the present invention relates to the elastic terminal for rail fastening. The elastic terminal (2) for fixing of rails with the U-shaped central section (20) and the bends (21, 22) passing through the torsion section (A) into curved holders (6, 27, 28) according to the present invention is characterized by that the torsion section (A) is the torsion section (KTS), free from bends, for which the 100<R<? is fair, where r is the radius of torsion section (KTS). The distance between neutral axes of the torsion section (A) and the respective holder (6, 27, 28) defines an arm (HA). The ratio of the torsion section (KTS), free from bends, to the arm (HA) is selected from the condition 0.05?KTS/HA?0.6. The holders (6, 27, 28) are bent so that their ends if look from above, are oriented against the central section (20).EFFECT: clamping force oscillations are minimized.7 cl, 5 dwg |
