Definitions

  • the present invention relates to a bogie brake for a rail vehicle bogie, the bogie comprising wheel sets journalled in longitudinal side frames connected by a transverse bolster and the bogie brake comprising transverse brake beams, each brake beam having a brake block holder at each end and being suspended from the bolster by suspension links.
  • Bogie brakes of the above type are well known in the art, one example being shown in EP-B-1 097 075, where brake actuators are mounted on the first brake beam and act on the second brake beam by means of push rods extending through the transverse bolster, so that a brake force is applied on the wheel treads in the wheel sets, when compressed air is admitted to the brake actuators.
  • a transmission rod extending in the longitudinal direction of the bogie, by means of upwardly extending means is connected at one of its ends to a pull rod of a pulling brake actuator in the first brake beam, the pull rod extending in the direction away from the second brake beam, and at the other end to the second brake beam and is suspended from the first brake beam by means of a suspension lever arrrangement.
  • the transmission rod is provided at each end with a vertically extending transmission flange arrangement for connection to the pull rod and the second brake beam, respectively.
  • the transmission flange arrangement for the second brake beam may preferably be pivotably connected around an axis perpendicular to the brake beam for allowing movements of the second brake beam in its plane (relative to the first brake beam).
  • the transmission flange arrangement may include link plates pivotably connected to and between plate profiles of the second brake beam by means of a pivot pin.
  • the active length of the transmission rod may have to be adjusted in accordance with the wear of the wheels in the wheel sets. This may be accomplished in that the position along the transmission rod of at least one of the transmission flange arrangements is adjustable.
  • suspension levers are pivotably attached to the transmission rod at their lower ends and to mounting flanges on the upper side of the first brake beam.
  • a rail vehicle bogie for two wheel sets 1 with wheels 2 has two side frames 3, in which the wheel sets are journalled and which are connected by a transverse bolster (not shown), to which an underframe (not shown) of the vehicle is journalled.
  • a bogie brake for this bogie primarily consists of two brake beams 4 and 5, which are suspended from the bolster (not shown) by means of suspension links 6.
  • Each brake beam 4 and 5 is at each end provided with a brake block holder 7 to be provided with a replaceable brake block 8 for braking engagement with the respective tread of the wheels 2.
  • each brake beam 4 and 5 is mainly composed of two L-shaped plate profiles, connected to each other in a way not further described.
  • the two shorter legs of the L:s are directed towards each other, and a pulling brake actuator or brake unit 9 is centrally mounted between the two plate profiles of the first brake beam 4.
  • the brake unit 9 is provided with a pull rod 10 extending to the left in Figs 1-3.
  • the two brake beams 4 and 5 are connected by means of a transmission arrangement shown most clearly in Fig 3 and - in its right portion - in Fig 4.
  • the main element of the transmission arrangement is a transmission rod 11 to extend in the longitudinal direction of the bogie below its bolster (not shown).
  • the transmission rod 11 has an upwardly extending, fixed transmission flange arrangement 12 to be pivotally connected at its upper end to the pull rod 10 of the brake unit 9 by means of a pin 10'.
  • the transmission rod 11 has an upwardly extending transmission flange arrangement 13, removably attached to the rod 11 by means of pins 13'.
  • the transmission flange arrangement has link plates 14 connected to the remainder of the arrangement 13 by screw connections 15 or the like.
  • the link plates 14 are pivotably connected to and between the plate profiles of the brake beam 5 by means of a pivot pin 16, so that pivotable movements between the brake beam 5 and the transmission flange arrangement 13 are possible.
  • suspension levers 17 are pivotably connected to the transmission rod 11 by means of a connection rod 18 and at their upper ends to mounting flanges 19 on the upper plate profile of the brake beam 4 at either side of the brake unit 9 by means of connection pins 20.
  • the position of the suspension levers 17 is chosen so as to minimize the moment influence on the transmission rod 11 of the vertical forces.
