Abstract

1.tope for railway and transverse vehicles, comprising a telescopic structure (10) formed by two tubular elements, respectively, external (12) and internal (14), of which one is intended to be fixed in one vehicle and the other it is provided with a contrast disc (32) and between which an elastic damping member (36,66) is axially interposed, characterized in that between said two tubular elements (12, 14) there is also interposed a fluid absorber dynamic (38). 2.tope, according to claim 1, characterized in that the fluid-dynamic damper (38) is arranged parallel to the damper elastic member (36, 66). 3.tope according to claim 1, characterized in that the fluid dynamic damper (38) comprises a cylinder (40) axially fixed to the outer tubular element (12) and whose cavity, which contains a damping liquid, is delimited by a elastically deformable wall (46), and a piston (56) sliding in the cylinder (40) linked to an axial rod (52) integral axially with the internal tubular element (14). 4.tope, according to claim 3, characterized in that said elastically deformable wall (46) of the cylinder (40) of the fluid-dynamic damper (38) is formed by an annular membrane of elastomeric material, whose internal surface is fixed to said rod (52) and whose outer surface is fixed to the side wall of the cylinder (40). 5.tope, according to claim 4, characterized in that the annular membrane of elastomeric material (46) has, in its non-deformed rest configuration corresponding to the extended condition of the stop, a substantially bellows conformation. 6.tope, according to or more of claims 3 to 5, characterized in that the elastic damper member (36, 66) is formed by a sleeve made of elastomer material (62), coaxially surrounding the stem (52) of the shock absorber (38) and whose ends support, respectively against said contrast disc (32) and against the corresponding end (44) of the cylinder (40) of the shock absorber (38), said sleeve of elastomeric material comprises a metallic framework constituted by a series of radial annular disks (64) axially separated. 7.tope, according to claim 6, characterized in that said metal discs (64) have the respective external circumferential edges contained, with a slight play, inside the internal surface of the internal tubular element (14). 8.tope, according to claim 6, characterized in that the sleeve of elastomeric material is formed by a series of rubber rings (68) interposed between each pair of adjacent metal discs (70). 9.tope, according to claim 6 or claim 8, characterized in that the metal discs (70) have the respective internal circumferential edges in contact with the surface of the shank (52) of the shock absorber (38). 10.tope for railway and trans-shipment vehicles.
