Definitions

  • the invention relates to an earth contact for transmitting the current of an electrically operated rail vehicle with internal wheels and external wheelset bearings on the wheelset shaft thereof, by means of brushes held by a brush holder, which are held by at least one spring against a contact closing body which is firmly connected to the wheelset shaft.
  • ground contacts are known for example from DE-AS-18 01 392.
  • Such ground contacts have the task of tracing the supply current of electrically operated rail vehicles, which is taken from an overhead line or a third rail, to the running rails in order to bridge the wheelset bearings with low resistance.
  • the grounding contacts must therefore provide a well-conductive connection between the return current cable and the rotating wheelset shaft in every operating situation.
  • ground contacts have so far been placed on an end face of the wheelset shaft and connected to the wheelset bearing for the purpose of securing against rotation.
  • grounding contacts cannot be used if, for example, an end-to-end arrangement is not possible due to excessive lateral protrusion or occupancy of the shaft ends with other devices and no suitable stationary fastening option is provided by external storage between the wheels. It is therefore the object of the present invention to provide a grounding contact of the type specified in the introduction, which can also be used when frontal mounting is not possible and when the wheel set bearings are not lying between the wheels.
  • This object is achieved according to the invention by two mutually opposite, at least partially encompassing the wheelset shaft, which are supported by means of sliders on the slip ring which encompasses the wheelset shaft and are held against rotation, at least the sliders of one part being designed as brushes.
  • a ground contact designed in this way can be mounted on the wheelset shaft between the wheels, even if the wheelset bearings are arranged outside the wheels.
  • the part which partially surrounds the wheelset shaft from above is designed as a housing which is secured against rotation by means of a torque rod fixed to the rail vehicle.
  • the part partially encompassing the wheelset shaft from below is designed as a rigid bracket which is attached to the housing by means of.
  • the slip ring is divided into two and has circumferential grooves for guiding and receiving the sliders. Another measure for assembly and ease of maintenance can be seen in the fact that the sliders are firmly connected to the housing.
  • the wheelset shaft is wrapped tightly by a support piece which has lateral guide legs, between which the slip ring parts encompassing the wheelset shaft are held and screwed onto the support piece.
  • the bracket is covered by a cover shell connected to the housing.
  • the housing has a receptacle for receiving a plug connected to the ground line.
  • At least one insulated power cable is led from this plug to the bracket. If the current is only to be conducted to the wheelset shaft via the carbon brushes and not via the sliders, it is advisable to insulate the connector from the housing. It has proven to be useful if the support consists of two half-shells screwed together.
  • a wheel set shaft which is comprised of two half-shell-shaped support pieces 2 and 3. These support pieces 2 and 3 have a U-shaped profile in cross section, the free legs 4 pointing outwards. With the support pieces 2 and 3, two approaches 5 and 6 are welded, which are screwed together by screws 7, so that the support pieces 2 and 3 form a unitary carrier and are clamped to the wheelset shaft 1.
  • a slip ring 7 ' is placed, which consists of two half-shells connected to each other by screws 8 and centering pins 9. The slip ring 7 'is secured against rotation and for attachment to the carrier 2, 3 by means of screws 10 which are screwed into the slip ring 7' through one leg of the carrier 2.
  • the outer circumferential surface of the slip ring 7 ' is profiled and has two trapezoidal grooves 11 running side by side.
  • These slide bearing segments 12 and 13 are connected via screws 14 to a housing 15, the latter, namely 15, an upper annular receiving projection 16, a Fastening bracket 17 and two connecting collars 18.
  • bearing blocks 19 are also connected to the housing 15, each of which carries a roller band spring 20 which is insulated from the housing 15. With the free-running ends of these springs 20 are provided with through-holes plates 21 which are screwed to the ends of a rigid bracket 22 which is made of electrically conductive material.
  • brackets 22 and carbon brushes 23 are shielded from below by a cover shell 27, the cover shell 27 being screwed to its collar 28 and the collar 18 of the housing 15.
  • a rod 30 carrying a joint 29 is screwed into the bracket 17.
  • a torque rod 31 engages, which is fastened with its end facing away from the joint 28 to the bogie, not shown, of a rail vehicle, so that the housing 15 and thus all parts connected to it are secured against rotation.
  • the current is derived exclusively via the carbon brushes 23, it is entirely possible within the scope of the invention to also design the slide bearing segments 12 as carbon brushes, the ohmic resistance being able to be determined as required by appropriate choice of material. In such a case, the plug 24 would not be insulated from the receiving attachment 16 or from the housing 15.
