Definitions

  • the invention relates to a method for manufacturing a rail vehicle and a rail vehicle.
  • Rail vehicles in particular rail vehicles for passenger transport and preferably rail vehicles for local public transport such as trams, light rail vehicles, underground trains or suburban trains and railcars for regional train services should have a maximum height difference between the boarding edge and a platform so that they are considered barrier-free.
  • Body torsion, component and assembly tolerances lead to different entry heights for each door in a car body.
  • coupled rail vehicles placed on bogies the problem is exacerbated when all the doors of a rail vehicle are compared with one another. It is not possible to compensate for these tolerances during the installation of the floor and sill panel, since these are at the very beginning of the assembly process and the overall tolerances of the rail vehicle are not yet known.
  • the differences can be compensated for by means of shims on the bogies or joints between the car bodies. Due to the coupling of the car bodies to each other, the level of the boarding edge can only be aligned with large remaining deviations from each other, especially in the case of articulated railcars.
  • the invention is based on the object of specifying an alternative possibility of reducing differences in the entry heights of the doors. Furthermore, the invention is based on the object of specifying a rail vehicle with such reduced differences in boarding heights.
  • the rail vehicle consisting of at least one car body and wheels is made available on a leveled track.
  • the car body has at least one door.
  • a height adjustment of a movable entry edge of the door is then carried out based on a predetermined height in relation to the leveled track. This is followed by a fixation of the entry edge.
  • the rail vehicle consists of several coupled car bodies.
  • the height adjustment and the fixing of the entry edge are carried out individually for all doors. This enables a simple manufacturing process in which shims on bogies and joints can essentially be dispensed with.
  • the car body includes a height-adjustable step strip.
  • the height of a boarding edge is adjusted by adjusting the variable height step bar.
  • all door areas of the car body or the car bodies have such a height-variable step strip and the height adjustment takes place for all height-variable step strips.
  • variable-height step bar comprises a bearing and a step bar surface.
  • the tread strip surface can be rotated about an axis by means of the bearing.
  • the height of the step bar is adjusted by rotating it around the axis. This allows easy height adjustment of the entry edge.
  • the boarding edge is fixed by fixing the height-variable step strip.
  • the height-variable step strip is fixed by means of at least one shim element between a support element that is firmly connected to the car body and the height-variable step strip. This allows for easy height adjustment and fixation.
  • the height-adjustable step strip is fixed by means of a screw connection. This also allows for easy height adjustment and fixation.
  • a first fixing element and a second fixing element are screwed together.
  • the first fixing element has a round through hole.
  • the second fixing element has an elongated hole. Either the second fixing element can be attached to the variable-height step strip and the first fixing element can be connected to the car body, or the first fixing element can be attached to the variable-height step strip and the second fixing element can be connected to the car body.
  • the first fixing element can have an elongated hole and the second fixing element can have a round through hole.
  • the height-adjustable tread strip is fixed by riveting or gluing or welding.
  • a height of the boarding edge can be adjusted by up to one hundred millimeters, preferably up to sixty millimeters, by means of the height adjustment of the boarding edge. This makes it possible to compensate for manufacturing tolerances in the car body.
  • the invention also includes a rail vehicle with at least one car body and wheels, the car body having at least one door.
  • the rail vehicle also has a height-adjustable boarding edge of the door that is fixed at a predetermined height. A height adjustment and fixing of the entry edge can be done with the method according to the invention.
  • the boarding edge is designed as a height-variable step strip.
  • the height-variable tread strip comprises a bearing and a tread strip surface.
  • the tread strip surface can be rotated about an axis by means of the bearing, and the height of the tread strip can be adjusted by rotating it about the axis.
  • FIG 1 shows a perspective view of a rail vehicle 10, which is designed as a tram vehicle.
  • the rail vehicle 10 has wheels 11 and a total of five car bodies 100 .
  • the rail vehicle 10 has an optional pantograph 20 and an optional train destination indicator 21, which is arranged on a front 30 of the rail vehicle.
  • an optional windshield 31 and a driver's stand 32 are arranged on the front 30 .
  • the rail vehicle 10 as a tram vehicle in this exemplary embodiment is a one-way vehicle. This means that doors 12 can only be opened on one side of the rail vehicle 10 are arranged. Furthermore, the rail vehicle 10 has optional windows 13 .
  • the rail vehicle 10 is designed as a two-way vehicle in an alternative embodiment not shown here, doors 12 can also be installed on the FIG 1 not be arranged visible side of the rail vehicle.
  • the rail vehicle 10 can in particular also be a tram vehicle, but also a light rail vehicle, a subway vehicle, an S-Bahn vehicle or a railcar for regional train services.
  • an optional boarding ramp 105 is arranged in the boarding area 102, with a height difference between the boarding edge 107 and the floor 101 being able to be overcome by means of the boarding ramp 105.
  • This can be used in particular in the case of trams, while the boarding area 102 is generally horizontal in the case of suburban trains or subways and the boarding ramp 105 can be omitted.
  • height-variable step strips 106 can also be provided for S-Bru or U-Bru trains, with which a boarding edge 107 can be adjusted.
  • the rail vehicle 10 consists of several coupled car bodies 100, as exemplified in FIG 1 shown, the height adjustment and the fixing of the entry edge 107 can be done individually for all doors 12. This enables a significantly simpler method of manufacturing the rail vehicle 10 compared to the complex methods of shims on bogies and joints of the prior art.
  • the car body 100 includes a step strip 106 that is variable in height.
  • the height of the boarding edge 107 can then be adjusted by adjusting the height-adjustable step strip 106 .
  • the variable-height tread strip 106 comprises a bearing 112 and a tread strip surface 111.
  • the tread strip surface 111 can be rotated about an axis.
  • the height of the step bar 106 is adjusted by rotating about the axis.
  • the height-variable tread strip 106 also has a support element 113 which is connected to the floor 101 .
  • the support element 113 can be firmly connected to the car body 100 .
  • a height of the tread strip surface 111 can be adjusted by means of the bearing 112 , with the tread strip surface 111 being able to rest on the support element 113 in a lowermost position.
  • the step strip 111 has a first front panel 115 on a side facing the door 12 and the support element 113 has a second front panel 116 on a side facing the door 12 .
  • a bolted joint 117 in 3 indicated by a dashed line, can be used to fix the variable-height step bar 106 .
  • a door seal 17 is shown at the lower end of the door 12, which extends to the first front panel 115.
  • the door seal 17 can in particular be designed in such a way that in all possible positions of the step strip surface 111 a tight seal of the door 12 on the first front panel 115 is produced by means of the door seal 17 .
  • the boarding edge 107 is fixed in place by the height-variable step strip 106 being fixed.
  • FIG 4 shows a front view of the height-variable step strip 111 and in particular the first front panel 115.
  • the first front panel 115 has two round through holes 118. In this case, the first front panel 115 can act as the first fixing element 131 .
