Definitions

  • the invention relates to a suspension of a rail brake according to the Generic term of claim 1.
  • a suspension is for example known from DE-A1-1 903 315.
  • a suspension device for magnetic rail brakes are considered pneumatic Lifting and lowering device stretching bellows body when compressed air is filled intended; since these bellows bodies are very soft across their axis, a unwanted swinging of the raised rail brake magnet through this Position (release position) engaging stops with cone-like Stop surfaces between rail brake magnets and vehicle frame locked out.
  • Such centering devices from cone and cone point in Release position (centered position) a very low elasticity (1-2 mm), connected with great rigidity, on. This will change the running characteristics of the bogie negatively affected at very high speeds.
  • the object of the invention is to suspend the in Specified type to design so that the rail brake in the release position compared to the bogie frame in the transverse direction to the rail with precisely defined Elasticity can be centered. Due to limited lateral mobility, the Running properties of the bogie of rail vehicles at very high Speeds are positively influenced.
  • the suspension using the rubber layer spring conveys one automatic centering, since the rubber layer spring runs along the guide chamfer is automatically insertable into the centering and is received flush in this.
  • the layering and material of the rubber layer spring can by elastic shear limited horizontal movement between the brake and the bogie frame. In a way this is a Decoupling the brake d. H. of the brake carrier with the arranged on it Brake magnets, opposite the bogie. Through the The rail brake even acts sideways in critical operating conditions as a vibration damper.
  • the transverse elastic centering with the help of Rubber layer spring can be used for rail brakes of any type, that is both with magnetic rail brakes and with eddy current brakes.
  • FIG. 2 of the drawing is a partially sectioned side view Bogie frame 1 of a rail vehicle shown, on which a Eddy current brake 3 is arranged in the manner described below.
  • the Bogie frame 1 on each side of the vehicle is resilient on axle bearings 5
  • two Wheel sets supported, lifting bellows 7 connected to the bogie frame 1 act via a bracket 8 on a brake carrier 9 of the eddy current brake 3 and this from the braking position shown in FIG. 2 of the drawing into the position in FIG. 3 are able to raise the release position shown, as explained below.
  • the rail brake in the present case as an example Eddy current brake shown, opposite the bogie frame 1 in the transverse direction be centered on the rail 13 with a precisely defined elasticity. Accordingly, it should be the Brake to be decoupled from the bogie in the rail plane, so to even influence the running properties positively.
  • Transversely elastic centering device 21 serves this purpose.
  • the upper part 23 of the centering device 21 is fixed the bogie, that is connected to the bogie frame 1, so by means of a Holder 25.
  • a connection to the bracket 8 and on Brake carrier 9 attached support plate 27 is a according to the invention Rubber layer spring 29 mounted, so z. B. by means of a screw connection 31.
  • Die Rubber layer spring 29 is constructed in multiple layers and has within certain Limits transverse elasticity; in the release position the rubber layer spring 29 with the help the bellows 7, the bracket 8 carried by him and the bracket connected support plate 27 pressed into a centering 33 of the upper part 23.
  • the Centering 33 is designed so that the rubber layer spring 29 when lifting and Entry into the upper part 23 automatically centered; as shown in Figure 1 the centering 33 is designed as a so-called chamfer.
  • On top of the Rubber layer spring 29 is a thicker plate 35 vulcanized, which with the Centering 33 serves as a guide and stop.
  • the rubber layer spring is chosen by choosing a suitable rubber compound and the number and height of the individual layers are set so that in vertical and horizontal level the desired (very different) Stiffness and damping values result.
  • the Rubber layer spring due to elastic shear a horizontal movement between the rail brake and the bogie frame.
  • the Running characteristics of the bogie positive at very high speeds affects d. H. the rail brake even acts as a vibration damper for critical ones Operating conditions.
  • the design of the rubber layer spring is different accessible.
  • Fig. are several horizontally lying Rubber layers through z. B. plates 37 connected to them by vulcanization, preferably metal plates, separated from each other.
  • the layers of the rubber layers and the plates can also run at an angle, such. B. V-shaped. It is also possible that the layers have different heights.
  • the centering according to the invention is not on the rail brakes shown in FIG. 2 and 3 illustrated embodiment limits d. H. it is also conventional Magnetic rail brakes applicable, in which the brake magnets in Rest the braking position on the rail. Also the construction of the bogie can differ from the illustrated embodiment.
