摘要:
The invention relates to a spring device (1) for absorbing transverse forces between a bogie frame and a wagon body on a rail vehicle. The spring device comprises a primary spring unit (2) and a secondary spring unit (3). The spring device (1) has at least one stop element (20) for bridging and in particular for limiting the spring travel of the secondary spring unit (3).

An arrangement for height compensation of a railway wagon comprises a device (7) with variable thickness arranged between the underframe (1) and at least one bogie (6) of the railway wagon for adjusting the distance between said two members.
摘要:
In order to disclose a device (1) having a pneumatic spring (2) for supporting a load on a bogie of a rail vehicle having a compressed air supply (4) which is pneumatically connected to the air spring (2) via an air spring valve (6) in order to vent and to fill the air spring (2) with compressed air, and having a control unit which is designed to adjust the air volume and/or the air pressure in the air spring (2) - a compressed air line (3) making available the pneumatic connection between the compressed air supply (4), air spring (2), air spring valve (6) and control unit - in which unnecessary filling and venting of the air spring (2) is prevented, means are proposed for limiting the volume flow (7) into the compressed air line (3) as a function of the speed of the rail vehicle.
摘要:
L'Invention est relative à un sommier basculant destiné à une suspension d'un véhicule pour assurer, d'une part, une reprise d'une charge verticale générée par la caisse du véhicule, et d'autre part, pour accompagner avec basculement des mouvements relatifs horizontaux, le sommier comportant un premier support pour son montage sur un élément du véhicule et un deuxième support espacé verticalement du premier support, pour recevoir une extrémité d'un ressort de suspension, caractérisé en ce qu'il comporte en parallèle : - un pivot central (50) de guidage vertical comportant un élément élastique (53) cylindrique ou tronconique monté entre une pièce interne (51) et une pièce externe (52), la pièce interne (51) étant solidaire de l'un desdits premier (70) et deuxième (71) supports et la pièce externe étant solidaire de l'autre desdits premier et deuxième supports, ledit pivot (50) présentant une raideur horizontale supérieure à sa raideur verticale, - et disposés symétriquement de part et d'autre du pivot central, au moins une paire de plots élastiques (60) dont les centres sont alignés sur un premier axe horizontal et qui sont montés entre le premier (70) et le deuxième (71) support et présentent une raideur verticale élevée par rapport à leur raideur horizontale.
摘要:
An improved side bearing (10) for railway cars is provided that achieves improved tracking and curving by the limitation of rock of the railway car. The side bearing comprises a base (12) with a generally upwardly extending wall portion (24). A cap (14) comprising a top section (26) with generally downwardly extending wall portion (28) is provided. The cap extends into or around the wall section of the base. Two coil springs (6, 18) are provided within the base that extend to the underside and support the cap. An elastomer spring (20) is also provided that is located within an least of one of the coil springs.
