Definitions

  • Rail vehicle in particular self-propelled rail vehicle
  • the invention relates to a rail vehicle, in particular a self-propelled rail vehicle according to the preamble of claim 1.
  • a contact element of a transmission device which interacts with a conductor rail serves to transmit operating current to a corresponding consumer, for example an electric motor and / or control signals to and from corresponding control devices of the rail vehicle.
  • Such rail vehicles are particularly suitable for small conveyor systems, for example in accordance with US Pat. No. 3,636,883.
  • Rail vehicles of the type mentioned are known for example from a small conveyor system according to US-A-3 636 883 and are used for example for the horizontal to vertical transport of small loads such as files, medical goods, components and much more. It is disadvantageous here that the contact elements scanning the conductor rails grind on the conductor rails and lead to a high level of noise, particularly when the rail separators are run over. In addition, there is abrasion, which not only pollutes the rail system and the vehicles, but also
  • the object of the invention is to develop a rail vehicle of the type mentioned at the outset in such a way that, with good transmission performance of the transmission device, noise and wear are reduced.
  • the contact element is formed as a contact roller essentially from carbon and / or graphite material which rolls on the conductor rail, the noise and wear are significantly reduced, in particular also when driving over switches, crossings, rail separators and the like.
  • This not only enables the contact rollers to have a longer service life, it also significantly reduces the pollution of the rail system, the rail vehicles and the environment, so that it is also possible to drive into clean rooms, for example in hospitals, without increasing the risk of contamination.
  • good data transmission with currents in the mA range, a permanent load in the range up to 20 to 30 A and short-circuit currents for drive motors in the range of 100 A or more are made possible without the contacts being damaged.
  • axes made of different materials can be used for the contact roller, but a silver-plated axis is particularly advantageous.
  • the contact properties can be improved by a floating bearing and thus by a higher adaptability of the contact roller of the conductor rail and the rail vehicle according to claim 3 and / or by pretensioning the contact roller against the conductor rail according to claim 4.
  • a further development according to claim 5 is also particularly advantageous, the contact roller being mounted in a bearing block, which in turn is preferably mounted in a floating manner in a holder of the rail vehicle.
  • a design according to claim 6 ensures appropriate preloading of the bearing block and thus of the contact roller against the conductor rail.
  • the transmission performance of the transmission device can be improved if at least two contact rollers are connected in series in the direction of travel.
  • Figure 1 in a partially sectioned section of a first embodiment of a rail vehicle with contact rollers supported on a conductor rail;
  • Figure 2 in a partially sectioned section of a second embodiment of a rail vehicle with contact rollers supported on a conductor rail. Ways of Carrying Out the Invention
  • the transmission device of a rail vehicle which interacts with a conductor rail 10 in order to transmit operating current and / or control signals from the latter to a self-propelled rail vehicle.
  • a rail vehicle is preferably part of a small conveyor system, for example in accordance with US Pat. No. 3,636,883, and is intended to transport small loads such as files, medical goods, components or the like.
  • contact rollers 14, 16 consisting essentially of carbon and / or graphite material are present according to the invention, for example at an operating voltage of 24 volts can easily transmit both small currents such as control currents in the range of 5 mA and currents in the order of magnitude up to 30 A in continuous load or short-circuit currents in the order of 100 A for drive motors without the risk of damage or destruction of contacts grows.
  • two contact rollers 14, 16 are provided one behind the other in the direction of travel in order to transmit the currents. It is also possible to use only one contact roller or more than two contact rollers or to arrange them side by side, for example in pairs.
  • the contact rollers 14, 16 are carried by a bearing block 18, which in turn is arranged in a holder 20, which forms a unit with the rail vehicle.
  • the bearing block 18 has a U-shape in cross section and, in the exemplary embodiment, has side legs with a trapezoidal geometry.
  • a contact pin 24 goes from the head part 22 of the bearing block 18 from which an electrically conductive connection to the drive motor 12 or control units, not shown, takes place.
  • the bearing block 18 and thus the contact rollers 14, 16 are electrically insulated from the holder 20.
  • a spring element 26 in the form of a spiral band spring acts on the bearing block 18 and is mounted in the holder 20.
  • a free S-shaped bent end section 28 of the spiral band spring 26 then acts on the head part 22 of the bearing block 18, so that in this way the required pretensioning of the bearing block 18 and thus the contact rollers 14, 16 in the direction of the conductor rail 10 is ensured.
  • the spring element 26, which starts from the holder 20 in the exemplary embodiment, is insulated from the bearing block 18.
  • at least the end section 28 cooperating with the bearing block 18 can be encased by an electrically insulating material.
  • the floating mounting of the bearing block 18 can take place in that either the preferably silver-plated axes 30, 32 of the contact rollers 14, 16 ge ass FIG. 1 are adjustable in elongated holes 34, 36 of the holder 20 running perpendicular to the conductor rail 10, or else the bearing block 18 according to the figure 2 itself is mounted via an axis 38 in corresponding elongated holes 40 of the holder 20. It must be ensured that the contact rollers 14, 16 or their axes 30, 32 or the axis 38 passing through the bearing block 18 are electrically insulated from the holder 20 or the holder 20 itself from the other parts of the rail vehicle. The same applies to the bearing block 18 itself.
