Definitions

  • the invention relates to an eddy current brake with a device for monitoring it Condition on a rail vehicle with a brake body facing the rail, the Brake body for grounding via an earth cable with a rail wheel of the rail vehicle is connected and on the rail vehicle is held over an insulating body.
  • an eddy current brake is part of the Brake body usually at least one electromagnet Facing rail. A current flow through such a magnet causes an eddy current in the rail and thus Braking the vehicle. If the eddy current brake at least one or more can be partially permanent Permanent magnets may be present.
  • Insulating bodies are required to keep currents out of the rail vehicle to guide past the brake body into the rail and the formation of current paths due to corrosion to avoid. Such current paths can, for example failure of an axle bearing and even blocking one Lead axis.
  • the brake body e.g. the magnets of the eddy current brake
  • temporarily put the rail on causing damage to the brake body could lead.
  • an insulating body on the bearing of the brake will be damaged could.
  • Such damage to the insulating body can by putting on the brake body but also by others external influences are caused.
  • the invention has for its object an eddy current brake with a device to monitor their condition, which both the unwanted attachment of the brake body on the rail, as well as damage to the insulating body, that would result in a current path allowed.
  • the object is achieved according to the invention in that the Earth cable is connected to an ammeter, the one Evaluation unit is connected downstream.
  • the brake body touches the rail, it results a conductive connection from the rail wheel via the underground cable and the brake body to the rail. Part of the stream that usually constantly from the rail vehicle via the rail wheel flows to the rail, then flows over the underground cable. There the current flow is recognized by the ammeter and then in the Evaluation unit evaluated.
  • the brake body consists, for example, of several pole coils, which are arranged between two end pieces. These pole coils have the function of electromagnets.
  • the brake body can also have permanent magnets.
  • the brake body has, for example, support arms that have insulating bodies are stored on the rail vehicle. You can do this Serve axle bearings.
  • the brake body over insulating body that electrically insulating bellows are suspended from the rail vehicle. Often there are both support arms and bellows.
  • the underground cable is, for example, a flexible grounding cable. This means that the required earthing is always provided.
  • the evaluation unit has, for example, a device for Detect the duration of an increased current.
  • a device for Detect the duration of an increased current In order to the advantage is achieved that when placing the brake body the duration of the touchdown recognized on the rail becomes.
  • the reliability of an eddy current brake during the operation of the rail vehicle e.g. is an ICE 3 can be monitored continuously.
  • Figure 1 shows as part of an eddy current brake of a rail vehicle several pole coils 3 arranged in a row are limited by end pieces 4.
  • the pole coils 3 and End pieces 4 form part of the brake body, the one Rail 1, on which the rail vehicle is moving, facing is.
  • a bogie is part of the rail vehicle shown. It consists of a bogie frame 6, are connected to the rail wheels 2.
  • the brake body has a pole shoe carrier 9 for the pole coils 3, the Attached to bogie frame 6 via insulating bellows 11 is.
  • the brake body support arms 10 which are electrical are isolated on axle bearing housings 5, which are supported by the Axle bearings of the rail wheels 2 are connected.
  • the bogie frame 6 is via its own underground cable 12 * and a resistor 13 connected to the bottom plate 7.
  • Figure 2 shows a bottom plate 7 of a railroad car from below with ammeters 14a to 14d integrated in underground cables.
  • Two evaluation units 8, with which the ammeter 14a to 14d connected via data lines 17 are each one Assigned bogie and via lines 18 with a diagnostic unit or a brake control unit 16.
  • Furthermore 2 shows components known from FIG.
  • FIG. 3 shows such a brake control device 16 in connection with an ammeter 14, which comprises a switch S1.
  • the Current meter 14 is assigned to the underground cable 12.
