Definitions

  • the invention relates to a grounding contact for an axle, in particular axle of a rail vehicle or the like, with a housing unit, a contact device and a sensor device, wherein the housing unit is formed from a housing body and a housing cover, wherein the contact device can be attached from an attachable to an axis sliding contact device and a Contact piece is formed, wherein between the sliding contact device and the contact piece, an electrical sliding contact can be formed, and wherein the sensor device is formed of a signal output device and at least one sensor for detecting operating parameters of the axis.
  • Earthing contacts are used regularly on axles of rail vehicles, in particular electrically driven rail vehicles. They serve to transfer electrical currents via an axle of a wheelset into a rail.
  • the known grounding contacts are regularly arranged on an axial side of an axis at this and rotatably with an axle bracket of the rail vehicle or relative to Axial side connected to this rotatable.
  • the earthing contact comprises a housing with a flange-like housing cover or a housing cover arranged on the axial side, contacts of graphite being in contact with the axle or corresponding slip rings or disks for transmitting a current within the housing.
  • a sensor device or a flange-like sensor housing is also known to attach to the housing cover.
  • the housing cover then has an opening through which, for example, a rotary encoder of the sensor device can detect signals generated by axle rotations. These signals are forwarded via a cable to a vehicle control, which generates therefrom an operating parameter, such as an axle speed, pulses for an engine control or a brake system, etc. That the sensor alone transmits a signal or a channel to the vehicle control system, as a result of which further processing of the signal for control purposes takes place.
  • Rail vehicle manufacturers use different signal structures for their respective vehicle controls, for example, in terms of amplitude, frequency, momentum, etc.
  • each rail network system for interaction with a rail vehicle also requires signals adapted to the particular rail network system.
  • a rail vehicle For example, for a rail vehicle to be operational on the rail network systems of two countries, it must be equipped with sensor devices that can provide the required signals. That is, a first ground contact is to be provided with a sensor or a signal output device for a first rail network system and a second ground contact is to be equipped with a sensor or a signal output device for a second rail network system.
  • a system change of a rail vehicle requires a far-reaching conversion of the same with an exchange or supplement of sensor devices.
  • the present invention is therefore based on the object to propose a ground contact for an axle, which simplifies a system change of a rail vehicle and a preparation of the grounding contact.
  • the earth contact according to the invention for an axle, in particular axle of a rail vehicle or the like comprises a housing unit, a contact device and a sensor device, wherein the housing unit is formed from a housing body and a housing cover, wherein the contact device consists of a sliding contact device which can be fastened to an axle and a contact piece wherein, between the sliding contact device and the contact piece, an electrical sliding contact can be formed, wherein the sensor device is formed by a signal output device to at least one sensor for detecting operating parameters of the axis, wherein the sensor device is disposed within the housing unit and the signal output device at least two in their Structure can issue distinctive signals.
  • the invention provides to arrange within the housing unit of the ground contact a sensor device which it allows to output at least two signals differing in their structure.
  • the advantage is achieved that in a system change of a rail vehicle no conversion of ground contacts or replacement of sensor devices must be made when the two signals are adapted to the respective rail network.
  • no two grounded contacts equipped with sensor devices are needed, but alone a ground contact provides the desired signals.
  • the differing signals may account for different vehicle controls of rail vehicle manufacturers. That is, a single ground contact is suitable for use in two different rail vehicles, thereby simplifying manufacture of the ground contact as a whole, since it is not necessary to produce two different sensor devices.
  • the signal output device can further process signal information of the sensor before outputting a signal. That the sensor device does not transmit signals originating solely from sensors to a vehicle control, but rather the respective signals can be further processed or modified in the signal output device such that an information contained in the signals is already adapted to a requirement of the vehicle control or a rail network system. The modification of sensor signals is therefore in the ground contact and not in the vehicle control.
  • the housing unit may be formed solely of the housing body and the housing cover. That is, the housing unit may be formed in two parts, thereby reducing the manufacturing cost of the grounding contact.
  • the earthing contacts known from the prior art in addition to a housing cover, regularly use further, adaptable housings of different shapes for a sensor device.
  • the senor may be a rotary encoder.
  • a rotary encoder allows signals to be obtained that can provide acceleration, speed, or even pulses for engine, door, or brake control.
  • the senor may be a temperature sensor which generates a temperature signal relating to the ground contact or the axis.
  • a current flow through the ground contact can be easily measured if the sensor is an ammeter. Accordingly, there is basically the possibility of equipping the grounding contact with a plurality of sensors, which can determine the above-mentioned measured variables by way of example.
  • the signal output device can output at least six signals differing in their structure.
  • a variety of vehicle controls and / or rail network systems can be covered or a variety of different signals can be obtained with a single ground contact alone.
  • a construction or production of a grounding contact can be further simplified if the sensor device is integrated in the housing cover. Should replacement of the sensor device nevertheless be necessary or different sensor devices are used, then it is only necessary to replace the housing cover without having to replace the entire grounding contact.
  • the housing cover is formed in one piece.
  • a use of multi-part housing covers, as known from the prior art, is then no longer necessary.
  • an improved sealing of the ground contact and a cheaper production are possible.
  • the ground contact may comprise an axle extension device, by means of which a sensor can be connected to an axle.
  • the Achsverinrungs leverage allows direct coupling of a sensor, such as a rotary encoder, with an axis.
  • the rotary encoder can then be placed anywhere in the Achsverinrungs worn within the housing unit.
  • the axle extension device can be mounted, for example, in the housing cover, so that a particularly smooth running of the axle extension device and thus particularly accurate measured values of the sensor can be achieved.
  • FIG. 1 and 2 shows a ground contact 10 on an axis of an electric locomotive, not shown here.
  • An axial end cap 11 of the axle is shown here with a dot-dash line.
  • a bearing block of the axis to which the grounding contact 10 is bolted is also not shown here to simplify the illustration.
  • the grounding contact 10 comprises a housing unit 12, which is formed solely from a housing body 13 and a housing cover 14. Screws 15 allow mounting of the housing body 13 on the bearing block.
  • a contact device 16 of the grounding contact 10 is here formed of a contact disk 17 and contact pieces 18 consisting essentially of graphite.
  • the contact pieces 18 are received in a contact piece holder 19 and are each pressed with a spring device 20 to form an electrical sliding contact against the contact disk 17.
  • the contact pieces 18 are further electrically connected by means of strands 21 to the contact piece holder 19, wherein at the contact piece holder 19, a connecting piece 22 with a cable 23, which connects the grounding contact 10 electrically in a well known manner with a motor connected.
  • a sensor device 24 is arranged, which is connected via an axle extension device 25 with the axis, not shown here.
  • the axle extension device 25 is rotatably mounted in the housing cover 14 and connected to a rotary encoder 26 of the sensor device 24.
  • Signals obtained by the rotary encoder 26 are further processed by a signal output device (not shown here in detail and designed as an electronic unit) within the housing cover 14 and transmitted via a signal cable 27 to a vehicle control of the electric locomotive which is not visible here.
  • the electronic unit is designed so that the encoder pulses obtained from the encoder 26 are converted into up to six different signals.
