Title (EN) SPRING ATTACHING DEVICE FOR A RAIL
(FR) DISPOSITIF DE FIXATION ELASTIQUE DE RAIL
Abstract: front page image
(EN)Attaching device for a rail by means of elastic fastenings of the type comprising a spring-forming elastic plate tightened by a bolt against a sleeper clip of plated plastic material bearing on the rail support and on the rail base. The spring plate has a triangular or trapezoidal known shape of which the bigger side bears in parallel onto the rail base and covers the plastic sleeper clip which has a substantially identical contour and presents thereto a corresponding concave bearing surface according to the desired deformation of the plate, substantially spherical and centered on the axis of the tightening mean. Application to railway constructions, particularly of the type of long rails, for high speed trains.
(FR)Dispositif de fixation de rail par attaches elastiques du type comportant une plaque elastique formant ressort serree par boulon contre un crapaud en materiau plastique plaque en appui sur le support de rail et sur le patin de rail. La plaque ressort ayant une forme connue triangulaire ou trapezoidale dont la grande base prend appui sur le patin de rail parallelement a celui-ci, le crapaud plastique qu"elle recouvre a sensiblement le meme contour et lui presente une surface d"appui correspondante concave selon la deformation recherchee de la plaque, sensiblement spherique et centree sur l"axe du moyen de serrage. Application aux constructions de voies ferrees, notamment du type a rails longs, pour trains a grande vitesse.
