Definitions

  • the invention relates to a brake device for railway vehicles with in the Preamble of claim 1 mentioned features.
  • Braking devices of the generic type are known. These as so-called Brake devices referred to brake rail brakes comprise two, in Substantially parallel to a running rail arranged brake beams.
  • the Brake bars are in this case with a distance to each other on the opposite Side of the rail arranged.
  • a brake drive By means of a brake drive are the Brake bar from a release position in a braking position and vice versa transferred.
  • the brake beams are on each other too moved, so that formed between the brake beam groove reduced. A width of this groove is reduced so far that this lower is the thickness of a wheel disc of a railway vehicle to be braked.
  • Such rail track brakes are, for example, as slope compensation brakes used in inclined arranged directional tracks of shunting.
  • slope compensation brakes By means of these slope compensation brakes is a deceleration of freely running Rail vehicles to brake these rail vehicles such that a run on other rail vehicles with an impermissibly high speed is prevented.
  • the braking device is characterized a strong mechanical Subjected to stress.
  • the essentially rigidly arranged brake beams force a corresponding to the lateral offset of the incoming wheel Change of direction of the incoming rail vehicle, so that considerable Shock and vibration loads on the components of the braking device such also be done on the wheels of the rail vehicle. At the same time this is hereby a strong noise.
  • the invention is therefore based on the object, a braking device of the generic type To create by means of a high load on the mechanical Assemblies of the braking device and the wheels and wheelsets of the railway vehicle is reduced in particular at the inlet of the same, the is simple, and with the environmental burdens of noise emissions are reduced.
  • this object is achieved by a braking device with the in Claim 1 mentioned features. Due to the fact that the brake beams at least in its braking position self-centering to a wheel of a braked railway vehicle are arranged, is advantageously achieved that these Self centering a simultaneous, substantially synchronous evasion of Brake bar - transverse to a direction of travel of an incoming rail vehicle - Allowed, without the brake position of the brake beams is canceled. This allows the braking device to the actual position of the incoming Rades react on the rail and on the incoming wheel automatically einjust Schl.
  • the brake beams non-positively connected to a spring-centered pliers arrangement.
  • a self-centering arrangement of Brake bar possible, at least in the braking position.
  • the spring-centered pliers arrangement ensures a simple way of deflecting the pliers lever, without causing a change in the forceps opening and thus a change the braking position of the brake bar results.
  • a position of the pliers lever leaves preferably set by a hydraulic cylinder, preferably the with the hydraulic cylinder operable ends of the pliers lever simultaneously with automatically adjusting a center position elastic elements, in particular Spring packs are operatively connected.
  • the Brake position causing hydraulic cylinder with water as hydraulic fluid is working.
  • environmentally relevant substances for example Hydraulic oil or the like can be dispensed with.
  • By adding antifreeze can the brake device safely at below freezing point of Operate water lying outside temperatures.
  • FIG. 1 shows a brake device, generally designated 10, for railway vehicles.
  • the braking device 10 is in a schematic sectional view shown, with their mode of action based on a partially illustrated Rades 12 of the railway vehicle takes place.
  • the wheel 12 runs on a rail 14th
  • the brake device 10 includes two brake beams 16 and 18 that are substantially are arranged parallel to the rail 14.
  • the brake beams 16 are on Brake levers 20 are arranged, which rotatably about an axis of rotation 22 at a bearing block 24 are hinged.
  • the bearing block 24 is frictionally with the Rail 14 connected.
  • a screw connection is used 26, which passes through the rail 14.
  • the brake levers 20 are above the axis of rotation 22 extended. Which the brake beams 16 and 18 opposite lying ends 28 form receiving lugs 30, to which about axes of rotation 32nd rotatably mounted elements 34 and 36 of a working means 38 are.
  • the element 36 is in this case with a single piston, not shown and the means 34 with a cylinder of the hydraulically acting working means 38 connected.
  • a pressure chamber of the working fluid 38 is connected to a pressure medium reservoir 40.
  • a pressure medium is offset, for example, with an antifreeze Used water.
  • the accumulator 40 is via a valve 42, in particular a solenoid valve, with a 41 designated reservoir, tank or the like connected to the pressure medium.
  • the reservoir 41 is also with an electrically driven hydraulic conveyor (hydraulic pump) 44 connected, the pressure outlet via a check valve 46 with the accumulator 40 is connected.
  • holding elements 48 are also hinged, which also about the axes of rotation 32 are rotatable.
  • the holding elements 48 are here connected in total with 50 designated spring elements.
  • the spring elements 50 comprise a spring 54 clamped between two plates 52 and 52 ' Plate 52 is frictionally connected to a connecting element 56 that on the other hand is non-positively attached to the support members 48.
  • the other Plate 52 ' is supported on a bearing block 58, the non-positively with a stationary arranged construction 60 is connected.
  • the construction 60 is for example a box-shaped structure that in a so-called threshold compartment of the rail 14 having track is arranged.
  • the bearing block 58 is penetrated by a guide pin 62, the non-positive is connected to the plate 52 '.
  • the guide pin 62 is merely this guided in a corresponding recess of the bearing block 58 and thus stored longitudinally movable.
  • the ends 28 of the brake lever 20 are also over a tension spring 64 connected to each other.
  • the tension spring 64 is in this case parallel to arranged the hydraulic working means 38.
  • Each of the ends 28 also has a stop element 66, which are formed substantially finger-shaped.
  • the Stop elements 66 form stop surfaces 68, which - as explained is - can be brought into abutment with a stop plate 70.
  • the stopper plate 70 consists of a resilient material, such as rubber or the like.
  • the braking device 10 has the following function:
  • FIG. 1 shows the brake device 10 in a braking position
  • Figure 2 shows the brake device 10 in a release position
  • the brake beams 16 and 18 are in a defined position to each other, wherein these are mounted rotatably about the axes of rotation 22.
  • the brake levers 20 via the elastic members 50 on the bearing blocks 58 supported.
  • the spring elements 54 of the elastic elements 50 are between the plates 52 and 52 'biased, wherein the plates 52 and 52' relative are movable relative to each other when one of the force of the spring elements 54 exceeds Force on the plate 52 - at the bearing block 58 adjacent plate 52 '- acts.
  • the inventive design of the braking device 10 is also achieved that the transverse to the rail 14 directed contact forces of the brake beams 16 and 18 to the wheel 12 and the bearing forces of the brake levers 20 each other cancel. As a result, no lateral forces in the superstructure of the Rail 14 having track initiated. Only the ones on the bearing blocks 58 supporting spring elements 54 lead to a minor Transverse force of the braking device 10, however, by the self-centering storage the brake lever 20 is negligible.
  • the stop plate 70 is made of an elastic material, are with the opening movement of the brake device 10 no large noise developments connected. Furthermore, the thus quasi-elastic support of the leads Brake lever 20 that when in befindlichem release position brake device 10 possibly extremely one-sided wheels 12 or very wide wheels 12 in touching contact can get to the brake beams 16 and 18, without this exerts a significant braking force. The levers 20 can thus deflect elastically transversely to a running direction of the wheels 12.
  • FIG. 3 shows a schematic plan view of the brake device 10
  • the two are substantially parallel to the running rail 14 extending brake beams 16 and 18 includes. in this connection are associated with the brake beams 16 and 18, two pairs of brake levers 20, the have the structure shown in FIGS 1 and 2.
  • the brake beams 16 and 18 extend here in the longitudinal direction of the running rail 14 over several Thresholds 72, wherein the housing 60 for receiving the drive means in Threshold spaces 74 are arranged. So it becomes clear that the braking device 10 can be easily integrated into a track bed, without a significant reconstruction of the track superstructure is required.
  • a further housing 76 arranged that the recording of the hydraulic components, in particular the hydraulic pump 44, the accumulator 40 and the reservoir 41, serves.
  • the control for the hydraulic pump 44 and the solenoid valve 42 may be integrated.
  • FIG. 4 once again shows a schematic side view of the brake device 10 shown, here - depending on the viewing direction - either the brake bar 16 or Brake bar 18 is shown. These are about the brake lever 20 and the bearing blocks 24 on the running rail 14, as described with reference to Figures 1 and 2, hinged.
  • the brake beams 16 and 18 comprise a stop element 78, which engages in a bearing element 80.
  • the Bearing element 80 is non-positively connected to the running rail 14.
  • the bearing element 80 forms two, in the longitudinal direction of the rail 14 before or behind the stop element 78 arranged blocks 82, which are spaced are arranged to the stop element 78.
