Definitions

  • the invention relates to a system with a rail vehicle that can be moved on rails and to which a guide carriage is attached.
  • a guide carriage is known as the closest prior art, which has a sliding surface for threading, which is spaced axially, ie in the direction of the axis of rotation of the wheels of the guide carriage, from the running surface of the wheels.
  • a sliding surface for threading which is spaced axially, ie in the direction of the axis of rotation of the wheels of the guide carriage, from the running surface of the wheels.
  • Running surface and sliding surface are arranged one behind the other in the axial direction, so that the track width when sliding is larger than the track width when the wheels roll.
  • the vertical projection of the sliding surface in the tread plane is at a distance from the treads of the wheels.
  • the sliding surface is arranged on the side of the running surface plane that faces away from the axes of rotation of the wheels. So when the skid hits the tread flush, the wheels can no longer roll on the tread as they are then held above the tread plane, ie on the side of the vehicle - but in the air.
  • the invention is therefore based on the object of developing a data transmission between the vehicle and a stationarily arranged controller in a robust manner.
  • sliding surface is flat and is aligned parallel to the plane
  • the advantage here is that the carriage is guided on the slotted waveguide. In this case, only rolling friction is present as power loss. Only when the slotted waveguide has a gap and thus a wheel arranged at the front in the direction of travel loses contact with the slotted waveguide does the guide carriage slide by means of the sliding surface on the slotted waveguide and the rear wheel. Thus, the guide carriage is held by the sliding surface until the front wheel has overcome the gap and rolls on the next slotted waveguide area.
  • the sliding plane is only a small distance from the rolling plane, that is to the running surface of the slotted waveguide, is arranged.
  • the carriage guides the antenna provided for data exchange with a stationary controller in the slot of the slotted waveguide as smoothly as possible, even if the rail vehicle deflects or fluctuates to the side of the rail, for example as a result of high manufacturing tolerances when manufacturing the system with rails.
  • the guide carriage is elastically connected to the rail vehicle and has wheels that guide it along the slotted waveguide and even center it in such a way that the antenna remains arranged in the slot, in particular without touching the slotted waveguide.
  • the track width when gliding is the same as the track width when the wheels roll off.
  • the distance between the axis of rotation of the wheels and the slotted waveguide is greater than the distance between the axis of rotation of the wheels and the sliding surface.
  • the perpendicular projection of the sliding surface in the plane overlaps with one of the running surfaces or with each of the running surfaces spaced apart from one another.
  • the advantage here is that either the respective wheel or alternatively the sliding surface is in contact with the running surface - but not both at the same time.
  • the vertical projection of the sliding surface in the plane overlaps with the vertical projection of a first wheel in the plane and with the vertical projection of a second wheel in the plane, in particular with the first wheel being spaced from the second wheel in the direction of travel.
  • the sliding surface is arranged between the wheels in the direction of travel, but is in alignment with the wheels. Thus, either the sliding surface or alternatively a wheel is in contact with the running surface.
  • the sliding surface is arranged between the plane and a second plane accommodating the spaced-apart axes of rotation of the wheels.
  • the distance between the axis of rotation of the wheels and the slotted waveguide is greater than the distance between the axis of rotation of the wheels and the sliding surface.
  • the advantage here is that the sliding surface is spaced apart from the tread plane for as long as the wheels roll on the tread. Only when a wheel comes below the level of the tread, for example due to a hole or gap, does the sliding surface begin to slide on the tread.
  • the distance between the axis of rotation of the wheels and the slotted waveguide is greater than the distance between the sliding surface and the slotted waveguide, in particular one of the running surfaces.
  • the rail direction of the rails is parallel to the drawing direction of the slotted waveguide produced as an extruded profile part.
  • the advantage here is that the slotted waveguide can be laid parallel to the rail and thus the antenna can be moved along the slot by the vehicle when moving.
  • the slotted waveguide is manufactured as an extruded profile part, with the cavity of the slotted waveguide opening into the environment via a slot running through the slotted waveguide.
  • an antenna is attached to the guide carriage, which protrudes through a slot of the slotted waveguide.
  • the advantage here is that the guide carriage guides the antenna along the slot, even if the rail vehicle is at a large distance from the antenna.
  • the tolerance in the movement of the guide carriage is smaller than that which can be implemented in the movement of the rail vehicle.
  • the carrier is designed as a frame-like structure wherein a connector clamps the antenna between two opposite sides.
  • a connector clamps the antenna between two opposite sides.
  • the antenna is arranged on a printed circuit board piece, in particular designed as a conductor track.
  • the sliding surface is arranged between the first and the second wheel in the direction of travel.
  • the carrier is mounted rotatably about a first axis of rotation on a swivel arm, which is mounted rotatably about a second axis of rotation on a support part, in particular a plate part. in particular wherein the first and second axis of rotation are aligned parallel to the axis of rotation of the wheels.
  • a compression spring supported on the supporting part presses the swivel arm in the direction of the slotted waveguide, wherein a tension spring attached to, in particular fastened to, the pivoting arm pivots the supporting part about the axis of rotation arranged between the supporting part and the pivoting arm.
  • the respective wheel in particular each wheel, has two running areas touching the running surface and two centering areas. in particular, the running area being cylindrical.
  • the advantage here is that the centering areas bring about the lateral guidance, ie in particular the centering in the direction perpendicular to the direction of travel.
  • no additional role runs on one Outer surface of the slotted waveguide, so that the outer surface can be used for a barcode or other coded sticker.
  • a reader can also be attached to the rail vehicle and thus detects the code in the area of the slotted waveguide not covered by the wheels, from which the position along the rail system can be determined.
  • the outer surface can therefore preferably be attached to the chimney-like edge region of the slotted waveguide.
  • the respective centering area is conical and/or adjoins the respective running area,
  • the outer diameter of the wheel in the centering area increases with increasing distance from the respective running area.
  • the centering area is arranged between the running areas in the direction of the axis of rotation of the wheel.
  • the advantage here is that the centering areas on the area of the slotted waveguide bordering the slot bring about the lateral guidance.
  • the outside diameter of the wheel in the direction of the axis of rotation of the wheel between the centering areas is smaller than each outside diameter of the cylindrical running areas.
  • the antenna covers an axial area in the direction of the axis of rotation of the wheel, which is arranged between the axial area covered by the centering areas. wherein the radial distance range covered by the antenna in relation to the axis of rotation of the wheel overlaps with the radial distance range covered by the wheel.
  • FIG 15 another embodiment of the invention is shown, in which, in contrast to the embodiment Figure 1 to 14 not only a single first swivel arm 5, but also a second swivel arm 5 is used.
  • the guide carriage has a carrier 1 which accommodates the axes of rotation of wheels 2 so that the wheels 2 are rotatably mounted relative to the carrier 1 and can roll on the slotted hollow conductor 9 .
  • the carriage is attached to a rail vehicle that is movable along rails.
  • the rail direction of the rails is parallel to the drawing direction of the slotted waveguide manufactured as a continuously cast profile part.
  • the guide carriage is thus moved along with the rail vehicle, being moved along the slotted waveguide 9 .
  • the rail vehicle is guided along the rails; however, fluctuations and/or shaking vibrations occur, so that the antenna 20 protruding into the slotted waveguide can only be held in position with sufficient accuracy by means of the guide carriage and contact between the slotted waveguide 9 and antenna 20 can be prevented.
  • connection plate 4 or another support part is attached to the rail vehicle.
  • a swivel arm 5 is rotatably mounted on the connection plate 4 and also rotatably mounted on the carrier 1, in particular with the axes of rotation of these two bearings being aligned in parallel.
  • a tension spring 3 arranged at the front in the direction of travel is arranged between the region of the carrier 1 and the swivel arm 5 at the front in the direction of travel. This prevents the front area of the guide carriage from sinking so far into the gap when crossing a gap between two aligned slotted waveguides 9, in particular slotted waveguide areas, that threading of the guide carriage is prevented.
  • pivoting movement of the pivoting arm 5 relative to the connection plate 4 or to the other supporting part is limited by a stop of the pivoting arm 5, with which the pivoting arm strikes the connecting plate 4 or the other supporting part.
  • the wheels 2 roll on the slotted waveguide 9 as long as there is no gap.
  • the carrier 1 has a sliding surface 70 on its side facing the slotted waveguide, which transitions in the direction of travel into a threading surface 110, in particular a centering surface, which is inclined to the sliding surface 70, ie in particular has a non-vanishing angle.
  • the sliding surface 70 is aligned parallel to the drawing direction of the slotted waveguide 9 produced as a continuously cast profile part.
  • the threading surface 110 and the further threading surface 110 adjoining the sliding surface 70 counter to the direction of travel are each aligned at an angle of less than 30° to the sliding surface 70 .
  • the slotted waveguide 9 has a continuous slot 10 which is aligned parallel to the drawing direction and whose boundary is designed like a chimney.
  • running surfaces are formed parallel to one another and evenly spaced in the direction of travel, on which the wheels 2 roll.
  • the running surfaces are preferably flat and parallel both to the direction of the axis of rotation of the wheels 2 and to the pulling direction of the slotted waveguide 9 designed as an extruded profile part.
  • the essential component of the spring force generated by the compression spring 21 presses the respective wheel 2 onto the respective running surface.
  • the wheel 2 has an intermediate area (121, 122) arranged between the running areas 120 rolling on the running surfaces, which dips into the slot 10, in particular into the slot 10 delimited by the chimney-like border.
  • This intermediate area has two conical sections 121, which act as centering surfaces 121 and between which a radial depression is formed, into which the antenna 20, which is embodied on a printed circuit board piece, protrudes at least partially.
  • the conical sections 121 of the wheels 2 each act as lateral sections, i.e. in particular in or against the direction of the axis of rotation of the wheels 2.
  • wheels 2 can also be designed with a radial indentation, which acts as a running area and thus centering on the running area can be carried out by shaping the wheel 2 .
  • the sliding surface 70 is at a distance from the slotted waveguide 9, in particular from the running surface, when both wheels 2, in particular the running areas of both wheels 2, of the guide carriage touch the running surface.
  • the front wheel 2 then comes into contact with another slotted waveguide 9 after it has been threaded in and the rear wheel 2 gets into the gap, where it is pushed a little further into the gap by the compression spring and the sliding surface 70 causes sliding friction with the further slotted waveguide .
  • the antenna 20 protrudes through the slot 10, in particular through the chimney-like boundary, into the cavity of the slot waveguide 9 and is thus able to couple electromagnetic wave components into and/or out of the cavity while driving. This enables data to be transmitted to other antennas that are stationary or attached to vehicles.
  • the carrier 1 has a frame-like structure. Two sides of the frame arranged opposite one another are thickened at least in the central area, so that the antenna 20 can be arranged in a gap 80 which is just still present between the two thickenings.
  • the two sides having the thickened areas are pressed together by means of connecting elements 7, in particular in the form of a threaded pin or screw with a nut, so that the antenna 20 is held in a non-positive manner, in particular clamped.
  • the gap 80 also has a curve in which a coaxial connector electrically connected to the antenna 20 is accommodated.
  • the guide carriage thus centers itself in the middle of the slot 10 and guides the antenna 20 as centrally as possible in the slot 10, but in particular without colliding with the slot waveguide 9.
  • the carrier 1 is made of plastic, in particular as a 3D printed part.
  • the wheels 2 are made of a plastic.
  • the antenna 20 is designed as an electrically conductive conductor track of a printed circuit board.
  • Each of the wheels 2 is preferably rotatably mounted via a respective grooved ball bearing.
  • first pivoting arm 5 in contrast to the aforementioned exemplary embodiment, not only a first pivoting arm 5 but also a second pivoting arm 5 is used, as in FIG figure 15 shown.
  • This is also arranged to be rotatable with respect to the connection plate 4 via an axis of rotation and to the carrier 1 around the first axis of rotation.
  • the two swivel arms 5 are arranged parallel to one another.
  • the carrier 1 is arranged between the swivel arms 5 along the first axis of rotation.
  • the rotatable mounting is designed with a further rotational degree of freedom, ie in particular a pivoting of the axis of rotation present between the carrier 1 and the pivot arm 5 is implemented.
