Description

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, however, lead to different entry heights for each door in a car body. In 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. In the case of a fully developed rail vehicle, 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 state of the art is to reduce larger differences in the entry heights of the doors by inserts on the bogies and joints between the car bodies. However, this is very expensive. Furthermore, differences in entry heights may still not be reduced to the required extent. The car bodies are finished and only then are the supplements installed in order to reduce the height differences.

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.

These objects are solved with the subject matter of the independent patent claims. Advantageous developments are specified in the dependent claims.

To craft a rail vehicle, the following steps are performed. First, 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.

By adjusting the height of the entry edge on the finished rail vehicle on the leveled track, height tolerances of the door entries can be compensated for without having to resort to the complex methods of using shims on bogies and joints. The increased requirements for barrier-free access to rail vehicles can thus be met more easily.

In one embodiment of the method, 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.

In one embodiment of the method, the car body includes a height-adjustable step strip. The height of a boarding edge is adjusted by adjusting the variable height step bar. In particular, it can be provided that 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.

In one embodiment of the method, the 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.

In one embodiment of the method, the boarding edge is fixed by fixing the height-variable step strip.

In one embodiment of the method, 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.

In one embodiment of the method, the height-adjustable step strip is fixed by means of a screw connection. This also allows for easy height adjustment and fixation.

In one embodiment of the method, 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. Furthermore, the first fixing element can have an elongated hole and the second fixing element can have a round through hole.

In one embodiment of the method, the height-adjustable tread strip is fixed by riveting or gluing or welding.

In one embodiment of the method, 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.

In one embodiment of the rail vehicle, the boarding edge is designed as a height-variable step strip.

In one embodiment of the rail vehicle, 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 . Of course, a different number of car bodies 100 can generally also be provided, in particular just one car body 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. Furthermore, 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 .

If 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. In this case, 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.

• Bereitstellen des Schienenfahrzeugs 10 bestehend aus mindestens einem Wagenkasten 100 sowie Rädern 11, wobei der Wagenkasten 100 mindestens eine Tür 12 aufweist, auf einem nivellierten Gleis 52;
• Höheneinstellung einer beweglichen Einstiegskante 107 der Tür 12 anhand einer vorgegebenen Höhe bezogen auf das nivellierte Gleis 52, wobei dies mittels der Höhenschablone 55 erfolgen kann;
• Fixierung der Einstiegskante 107.

FIG 2 shows a cross section through a rail vehicle 10 during manufacture. In particular, a cross section through a car body 100 is shown which, as in FIG FIG 1 shown can be configured. The rail vehicle 10 is arranged on a level track 52 with two rails 51 . A floor 101 is arranged in an interior 15 of the rail vehicle 10 . The rail vehicle 10 can be entered from a door 12 . A height template 55 specifies a predetermined boarding height to which an boarding area 102 of the rail vehicle 10 is to be adapted. The height of the height template 55 can be aligned with the conditions of a rail network, for example a tram network. In order to produce the rail vehicle 10, the following method steps can be carried out:

• Providing the rail vehicle 10 consisting of at least one car body 100 and wheels 11, the car body 100 having at least one door 12, on a leveled track 52;
• height adjustment of a movable boarding edge 107 of the door 12 based on a predetermined height relative to the leveled track 52, which can be done by means of the height template 55;
• Fixation of the entry edge 107.

By adjusting the height of the boarding edge 107 on the finished rail vehicle 10 on the leveled track 52, height tolerances of the door entrances or the boarding areas 102 can be compensated for one another without having to resort to the complex methods of shims on bogies and joints. The increased requirements for barrier-free access to the rail vehicle 10 can thus be met more easily.

In FIG 2 Furthermore, 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. Irrespective of this, height-variable step strips 106 can also be provided for S-Bahn or U-Bahn trains, with which a boarding edge 107 can be adjusted.

If 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.

also in FIG 2 it is shown that 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 .

3 shows a cross-section through a height-variable tread strip 106, such as that shown in FIG 2 can be used. The variable-height tread strip 106 comprises a bearing 112 and a tread strip surface 111. By means of the bearing 112, the tread strip surface 111 can be rotated about an axis. means 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.

also in 3 It is shown that 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 . also in 3 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 .

In one exemplary embodiment, 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 .

5 shows a front view of the support element 113 and in particular the second front panel 116. The second front panel 116 has two elongated holes 119. In this case, the second front panel 116 can act as a second fixing element 132 .

By means of the through holes 118 of the first front panel 115 and the elongated holes 119 of the second front panel 116, the screw connection 117 can be produced after the height of the variable-height step strip 106 has been adjusted. Furthermore, an embodiment is also possible in which the through holes 118 are arranged in the second front panel 116 and the oblong holes 119 are arranged in the first front panel 115 . In addition, more than two through holes 118 and more than two oblong holes 119 can also be provided, it being possible for the number of through holes 118 and oblong holes 119 to be identical.

6 shows a further variable-height step bar 106, which can also be used to adjust the height of the boarding edge 107. In this case, the setting and/or fixing of the variable-height step strip 106 is effected by means of at least one shim element 121 between the support element 113, which is fixedly connected to the car body 100, and the slat surface 111 of the variable-height step strip 106. In a lowest position, the shim elements can also be dispensed with. In 6 four underlay elements 121 are arranged between the support element 113 and the tread strip surface 111, the exact number of underlay elements 121 being able to be selected and used on the basis of the height template 55. In the lowest application, shim elements can also be dispensed with, depending on the design.

also in 6 The first front panel 115 of the tread strip surface 111 is shown. Since the fixation takes place by means of the shim elements 121, the second front panel 116 of the support element 113 is not necessary. Furthermore, in 6 shown that the tread strip surface 111 is optionally screwed to the support element 113 by means of a screw connection 117 guided through the shim elements 121 .

The kick bar 111 of figure 3 you can also with the underlay elements 121 of 6 combine. With that one can implement simpler screwing with reduced shear forces.

FIG 7 shows a cross section through another rail vehicle 10 during manufacture, which corresponds to the rail vehicle 10 of FIG FIG 2 provided that no differences are described below. In this exemplary embodiment, the entire boarding ramp 105 is designed as a height-variable step strip 106 with which the height of the boarding edge 107 can be adjusted. This means in particular that the step strip 106 , which is variable in height, has larger dimensions into the passenger compartment 15 when viewed from the door 12 . In particular, an incline of the boarding ramp 105 can be adjusted with the height-variable step strip 106 . This enables an even more flexible manufacturing process, since significantly larger differences in height of the boarding edge 107 can be set here. Thus, for example, rail vehicles 10 can be produced for different networks with different boarding heights, which differ only in the gradient of the boarding ramp 105 and which are adapted to the specified boarding heights. The rail vehicles 10 can thus be produced more cost-effectively.

The fixation of the variable-height step bar 106 and thus the boarding ramp 105 can be as in connection with the 3 to 6 explained.

8 shows a side view of the variable-height step bar 106 of FIG FIG 7 with a further possibility for fixing the step strip surface 111. The support element 113 has first fixing elements 131 with round through holes 118. The step strip surface 111 has second fixing elements 132 with elongated holes 119. Here, too, a screw connection 117 can be formed through the through holes 118 and the elongated holes 119 after the height of the entry edge 107 has been adjusted.

Alternatively or additionally, the height-adjustable step strip 106 can be fixed by riveting or gluing or welding. Furthermore, by adjusting the height of the boarding edge 107, a height of the boarding edge 107 can be adjusted by up to one hundred millimeters, preferably up to sixty millimeters.

As related to the 2 to 8 explained, the rail vehicle 10 of FIG 1 ie a height-adjustable boarding edge 107 of the door 12 fixed at a predetermined height. The boarding edge 107 can be designed as a step bar 106 that is variable in height. The variable-height step bar 106 can include a bearing 112 and a step bar surface 111, the step bar surface 111 being rotatable about an axis by means of the bearing 112 and the height of the step bar 106 being able to be adjusted by means of a rotation about the axis. In particular, each of the doors 12 of the rail vehicle 10 can have a boarding edge 107 fixed at a predetermined height.

Although the invention has been illustrated and described in detail by the preferred embodiment, the invention is not limited by the disclosed examples and other variations can be derived therefrom by those skilled in the art without departing from the scope of the invention.
