Definitions

  • the invention relates to an arrangement for the movable suspension of block brake units for steering axles or radially adjustable wheel sets of rail vehicles on the vehicle or bogie frame and for their support in the longitudinal direction of the frame.
  • the invention has for its object to provide an arrangement of the type mentioned, which ensures a constant brake pad play with simple and inexpensive construction and reliable operation and ensures that the brake pad holder of the pad brake unit is always aligned parallel to the tread of the associated wheel and the wheel also remains steerable when braked.
  • the block brake unit 1 is assigned to a wheel 2 of a rail vehicle, which rolls on a rail 3, has a wheel flange 4 and belongs to a wheel set which is arranged in a bogie frame 5 such that it moves into a radial position with respect to the same when passing through a track curve can.
  • the block brake unit 1 interacts with the wheel 2 by means of a brake block holder 8 provided with brake blocks 6, 7 and has a brake cylinder, a transmission gear and a stroke actuator for actuating the brake block holder 8, which can function as shown in DE 41 17 632 A1 and described, and which are housed in a housing 9.
  • the brake pad holder 8 is suspended using a hanging bracket 10 and a parallel link 11, as suggested in patent application P 42 35 310.6 dated October 20, 1992.
  • the block brake unit 1 is pivotally connected to the bogie frame 5 at the upper end 12 about an axis 14 which is substantially parallel to the axis 13 of the wheel 2. Furthermore, it is connected to the outer axle bearing housing 16 adjacent to the wheel 2 approximately at the level of the wheel axle 13 by means of a lateral coupling rod 15 which runs essentially perpendicular to the wheel axle 13.
  • the block brake unit 1 is provided on the side facing away from the wheel flange 4 of the wheel 2 with a protruding pin 17 on which the adjacent end 18 of the coupling rod 15 is supported in the manner of a ball joint.
  • the other end 19 of the coupling rod 15 is articulated to the outer axle bearing housing 16.
  • the hanging bracket 10 is pivotally connected to the bogie frame 5 at the upper end 20 facing away from the brake block holder 8 about the same axis 14 as the block brake unit 1.
  • the parallel link 11 is at the upper end 21 facing away from the brake block holder 8 about a common pivot axis 14 of the block brake unit 1 and the hanging bracket 10 parallel axis 22 pivotally connected to the bogie frame 5.
  • the block brake unit 1, the hanging bracket 10 and the parallel link 11 are pivotally mounted on a bracket 23 which is fastened to the bogie frame 5 by means of screws 24.

Claims (4)

  1. Agencement pour la suspension mobile d'unités de frein à sabot destinées à des essieux directeurs de véhicules sur rails ou à des essieux montés de véhicules sur rails se réglant radialement dans des courbes de voie, au châssis du véhicule ou d'un bogie, ainsi que pour le soutien de ces unités de frein à sabot dans la direction longitudinale du châssis, caractérisé en ce que l'unité de frein à sabot (1) est reliée, à l'extrémité supérieure (12), au châssis (5) du véhicule ou du bogie, de manière à pouvoir pivoter autour d'un axe (14) sensiblement parallèle à l'axe (13) de la roue associée (2), et est reliée, à peu près à hauteur de l'axe (13) de la roue, au carter (16) du palier extérieur d'essieu voisin de la roue (2), par l'intermédiaire d'une bielle de couplage latérale (15) s'étendant sensiblement de manière perpendiculaire à l'axe (13) de la roue.
  2. Agencement selon la revendication 1, caractérisé en ce que l'unité de frein à sabot (1) présente un support de sabot de frein (8) suspendu de manière oscillante au moyen d'une biellette de suspension (10), et en ce que la biellette de suspension (10), à l'extrémité supérieure (20) située à l'opposé du support de sabot de frein (8), est reliée au châssis (5) du véhicule ou du bogie, de manière à pouvoir pivoter autour du même axe (14) que l'unité de frein à sabot (1).
  3. Agencement selon la revendication 2, caractérisé en ce que l'unité de frein à sabot (1) présente, pour le support de sabot de frein (8), un bras oscillant parallèle (11) qui, à l'extrémité supérieure (21) située à l'opposé du support de sabot de frein (8), est relié au châssis (5) du véhicule ou du bogie, de manière à pouvoir pivoter autour d'un axe (22) parallèle à l'axe de pivotement commun (14) de l'unité de frein à sabot (1) et de la biellette de suspension (10).
  4. Agencement selon la revendication 1, 2 ou 3, caractérisé par une console (23) vissée sur le châssis (5) du véhicule ou du bogie, sur laquelle sont montés pivotants l'unité de frein à sabot (1) et, le cas échéant, la biellette de suspension (10), ainsi que, le cas échéant, le bras oscillant parallèle (11).
