  • GB-PS 858 933 shows a single-stage spring-loaded undercarriage in which a undercarriage frame is supported on the axle bearings and is guided to them via a jaw guide.
  • a suspension is arranged on the chassis frame, on which a car body is supported by specially designed upper spring plates.
  • the spring plates have vertical guides in the longitudinal direction of the chassis, each of which is engaged by a correspondingly configured vertical pin that is firmly connected to the chassis frame.
  • the momentary support of a wheelset gear is on the chassis frame supported and the chassis frame stabilized with a double handlebar arrangement in relation to the car body.

  • this movement is transmitted directly to the axle bearing housing 6, 6'.
  • the same-direction unscrewing movement of the T-shaped lever 19 and the L-shaped lever 20 is converted into an opposite longitudinal movement of the link arrangement 3, 3 'on both sides and transmitted to the axle bearing housing 6, 6', so that the wheel set 1 together with one associated component frame 30 is set to be curve-radial regardless of the wear state of the rails.
  • the trailing arms 13, 14 and 13 ', 14' arranged on both sides parallel to one another have the effect that the wheel set 1 is guided and the axle bearing housings 6, 6 'are stabilized, so that the spring support flattened 7, 7 'under the influence of vertical deflection 8, 8' do not perform any tilting movements.

Abstract

L'invention concerne un dispositif de support, de positionnement et de guidage d'un jeu de roues freinées et/ou entraînées de véhicules sur rails, qui sont montées des deux côtés dans des paliers d'essieu logés dans des logements de palier. Les logements de palier (6,6') sont positionnés et guidés par un dispositif de direction (3,3') et soutenus par rapport à un dispositif de guidage (4) , le dispositif de guidage (4) étant placé contre une caisse (2), laquelle est montée sur les logements de palier (6,6') au moyen d'une suspension (8,8'). Afin de réduire le poids, on n'a pas équipé le train de roulement de son châssis habituel. Le réglage par rapport au rayon des virages est sensiblement indépendant de l'état des rails et de la géométrie de contact roue/rail obtenue.
