Definitions

  • Rail vehicle car with a car roof with a flat roof area and a raised area
  • the invention is in the field of rail vehicle technology and relates to a rail vehicle car for local, regional and long-distance passenger traffic with a car roof with a flat roof area and a raised area.
  • Modern rail vehicle cars in particular those with a high proportion of low-floor vehicles, carry a large part of the traction equipment on the roof, since there is little space left for the traction equipment due to the small installation space below the low-floor area. Because of the need to use the interior of the rail vehicle car as optimally as possible for the passengers and to maximize the number of seats, there is also only a limited amount of space available for technical equipment within the rail vehicle car. Some of these technical equipment components are therefore housed above the inner ceiling and between the inner ceiling and the actual car roof.
  • the aim is to have a roof of a rail vehicle with the same height as possible over the entire length of the rail vehicle.
  • some of the technical equipment components are bulky and require an increased amount of space.
  • roof trays are often provided for local lowering in the car roof, which creates additional space.
  • roof tubs need drainage so that rainwater can drain away.
  • dirt can easily collect in a roof tub, so that it needs to be cleaned regularly.
  • components housed in roof troughs are exposed to greater corrosion because of the generally increased moisture there.
  • Rail vehicle cars with local roof troughs are described in the documents US 2014/0 250 800 A1, EP 1 006034 B1 and EP 1 839 989 B1.
  • the publications DE 60006864 T2 and EP 1 566322 B1 describe rail vehicle cars with a car roof with areas of different heights.
  • a rail vehicle car has a car body with side walls and a car roof connecting the side walls with a flat roof area, as well as an inner ceiling which is spaced from the car roof and delimits an installation space between the car roof and the inner ceiling.
  • An elevation is provided in the car roof which defines a raised area of the car roof and locally expands the installation space between the car roof and the inner ceiling.
  • An interior component is accommodated, for example partially or completely, in the installation space within the raised area.
  • the flat roof area has a lower height so that larger external components can be mounted on the flat roof area without the need for a roof trough. Due to the overall lowering of the car roof, however, the installation space below the car roof is reduced. This installation space is limited at the bottom by the interior ceiling, which cannot be lowered at will. For larger interior components there would therefore no longer be sufficient space to accommodate them in the installation space between the interior ceiling and the car roof.
  • the installation space can have a first area above a lower edge of the flat roof area up to the maximum interior height of the raised area and a second area above the inner ceiling as far as the lower edge of the flat roof area.
  • the installation space is therefore extended vertically in the raised area of the car roof compared to the installation room in the flat roof area, i.e. it extends from the inner ceiling continuously to the maximum interior height of the raised area.
  • the installation space in the raised area can therefore have a greater vertical extent than the installation area outside the raised area, i.e. in the flat roof area.
  • the interior component accommodated in the raised area in the installation space can extend from the second area into the first area.
  • the second area can extend laterally into the flat roof area.
  • the height of the car roof was determined so that all equipment components (interior components) that are to be integrated below the car roof can be integrated there without having to lower the interior ceiling.
  • equipment components on the car roof external components
  • additional installation space was provided on the car roof through the roof tray.
  • the solution presented here takes a different approach.
  • the roof of the car is set a little lower overall, so that all equipment components that have to be mounted on the roof of the car, i. H. the external components have sufficient space.
  • the flat roof area can have a height, starting from the upper edge of the rail, between approximately 3450 mm and 3550 mm, preferably approximately 3500 mm. Only in those places where larger interior components are to be installed in the installation space between the car roof and the inner ceiling is the car roof raised locally and thus the installation space expanded.
  • the area ratio between the flat roof area and the raised area is greater than 1: 1, preferably greater than 6: 4, further preferably greater than 7: 3, and in particular greater than 3: 1.
  • the flat roof area therefore takes up at least 50% of the car roof, preferably significantly more. Since larger external components can be accommodated in the flat roof area, the solution presented here expands the space for the installation of larger external components. In previous solutions with a roof trough, the space for the installation of larger external components was limited to the area of the roof trough, which typically took up significantly less than 50% of the total area of the car roof.
  • the car roof therefore preferably does not have an inwardly curved roof pan. An additional drainage device and necessary periodic cleaning can therefore be dispensed with.
  • a further interior component is arranged outside the raised area in the installation space between the interior ceiling and the car roof.
  • the installation space can also extend outside the raised area into areas that are only limited at the top by the flat roof area. It is also possible for the installation space between the inner ceiling and the car roof to extend over the entire length of the rail vehicle car. Below the flat roof area, when the height of the inner ceiling is constant, the installation space, viewed in the vertical direction, is less than in the raised area. Smaller interior components that do not require a large amount of vertical installation space can therefore also be installed in the installation space below the flat roof area.
  • the elevation viewed in a direction transverse to a longitudinal direction of the rail vehicle car, is spaced from the respective side wall of the car body.
  • a narrow strip of the flat roof area can then run between the elevation and the respective side wall, ie the flat roof area continues laterally next to the elevation area in the longitudinal direction.
  • the outer contour of the car roof starting from the side wall, or from a transition between side wall and car roof can initially run essentially flat and then merge with a step into the elevation. You can do that on the opposite side Car roof over another step in a flat course up to the opposite side wall or the transition there between side wall and car roof.
  • the car roof is viewed as a roof panel, the car roof is raised within the roof panel and spaced from the lateral edges of the roof panel and thus from the side walls of the rail vehicle car. This enables a cost-effective production of the car roof with the elevation.
  • the car body with the side walls and the car roof is designed in a self-supporting construction with self-supporting structures or structural elements.
  • the elevation of the car roof is part of the self-supporting structure of the car roof. The increase therefore does not have to be reinforced by other structural elements.
  • an external component located on the elevation can be carried directly by the elevation without the need to provide other supporting structures.
  • the car body with the side walls and the car roof is designed in a self-supporting construction with self-supporting structures or structural elements.
  • the elevation of the car roof is not an integral part of the self-supporting structure of the car roof.
  • the car roof must be designed in such a way that the stability of the car roof is guaranteed despite the increase, which does not contribute to the stability of the car roof or only insignificantly.
  • a suitable carrier can be provided around the elevation in the car roof, on which the elevation is supported and which gives this area sufficient stability.
  • the carrier can run below the car roof, in the plane of the car roof, or run on the car roof and have an opening in the Reinforce the self-supporting structure of the car roof, on which the elevation is then supported.
  • the car body with the side walls and the car roof is designed as an integral construction.
  • the self-supporting structures are self-supporting extruded profiles which form parts of the outer skin of the rail vehicle car. This means that different cross-sectional geometries can be efficiently implemented.
  • the elevation seen in cross section transversely to the longitudinal direction, has a distance from the side wall or the transition between side wall and car roof of about 380 mm to 450 mm, preferably from about 400 mm to about 440 mm, in particular from about 420 mm .
  • the car roof is preferably flat, ie. H. the flat roof area also extends to the side next to the elevation.
  • the elevation has a height compared to the flat roof area of about 50 mm to about 200 mm, preferably of about 50 mm to about 150 mm, in particular of about 100 mm, for example at the heights of the flat roof area above the top edge of the rails specified above, z. B. of 3450 mm.
  • a fastening rail is fastened on both sides next to the elevation on the car roof, each of which runs in the longitudinal direction of the rail vehicle car.
  • the fastening rails which can be C-rails, for example, are used to fasten the external component or other equipment.
  • the fastening rails can be integrated into extruded profiles of the car body.
  • These cables are preferred by suitable ones Fasteners are connected directly to the car roof and are not routed through a cable duct.
  • the rail vehicle car has an interior floor, a high-floor area and a low-floor area.
  • the interior floor has a height above the upper edge of the rail, which is higher than the height of the interior floor in the low-floor area.
  • the inner ceiling has predominantly or entirely a uniform height above the upper edge of the rail both in the high-floor area and in the low-floor area.
  • the inner ceiling is therefore preferably equipped with a uniform height throughout the rail vehicle car. It does not follow the different heights of the floor in the low-floor area and the university area. This is advantageous for the structural design of the interior ceiling.
  • an attractive appearance of the interior of the rail vehicle is achieved.
  • the interior floor in the high-floor area can be designed to be relatively low compared to previous rail vehicle cars. Fewer components are arranged underfloor for this purpose, i.e. compressed air supply / devices, traction motor fans. On-board batteries with an extra flat design are arranged in the low-floor area. Larger components are then integrated either on the car roof or in the installation room.
  • At least one external component which can be a transformer, converter, traction batteries or traction cooling system, is mounted in the flat roof area on the car roof.
  • at least two, at least three or more external components can also be mounted in the flat roof area.
  • At least one further external component which can be high-voltage equipment and / or an air conditioning system, is mounted on the elevation.
  • the interior component can be which is housed in particular in the raised area of the car roof to act as control components, air conditioning or compressed air components.
  • the car roof comprises at least two flat roof areas, which are each located at the front ends of the rail vehicle car and above drives (e.g. bogies) of the rail vehicle car, and at least one raised area with at least one elevation between the two flat roof areas.
  • the car roof comprises a (single) flat roof area, which is located at a front end of the rail vehicle car and above a drive (e.g. bogie) of the Rail vehicle wagon is located, and a (single) raised area with an elevation that adjoins the flat roof area and extends to the other end of the rail vehicle wagon.
  • the rail vehicle carriage can thus either have an elevation approximately in the middle - based on the longitudinal extent of the rail vehicle carriage - or an elevation extending up to a front end of the rail vehicle carriage.
  • Rail vehicle cars can thus be designed differently depending on their function. For example, in the case of a multiple unit comprising several rail vehicle cars, the roof of the leading rail vehicle car can be designed differently than, for example, a following rail vehicle car.
  • FIG. 1 shows an embodiment of a rail vehicle wagon with a flat roof area that extends to a front end of the rail vehicle wagon, and a raised area that extends to the opposite front end of the rail vehicle wagon.

  • Another specific embodiment includes the arrangement of traction batteries as external components 141, especially for battery-operated ones Rail vehicle wagons. Since the flat roof area 151 is somewhat lower overall compared to the height of the roof of previous rail vehicle cars, larger ones can also be used Traction batteries can be mounted on the flat roof area 151.
