Definitions
- Rail vehicle with an underframe for holding supply lines
- the invention relates to a rail vehicle according to the preamble of claim 1.
- a rail vehicle is provided with an underframe which has a section which is assigned to a chassis area of the rail vehicle and has a space for receiving supply lines.
- the chassis area of such a rail vehicle it is necessary that sufficient installation space is available to accommodate supply lines for electrical and / or pneumatic components. These supply lines can both be routed past the chassis area and also be provided to supply certain components of the chassis, such as, for example, a supply of compressed air to the air spring of the chassis.
- the installation space situation in the chassis area can vary greatly for different rail vehicles.
- the available installation space results, among other things, from different widths of the rail vehicle, the height of the rail vehicle structure and specifications with regard to the height of the floor of an interior of the rail vehicle.
- the installation space is influenced by the intended chassis and its movements when the rail vehicle is in operation.
- the invention is based on the object of further developing the rail vehicle of the type mentioned at the beginning. to develop that suitable installation space is provided for the supply lines.
- This object is achieved by a rail vehicle with the features of claim 1.
- This rail vehicle is characterized in that the section of the subframe assigned to the chassis area has a single-shell base plate with bulging stiffeners running in the longitudinal direction of the subframe, the interior of which has the installation space to accommodate the supply lines forms.
- the provided buckling strips thus provide an interior space accessible from one side, which can be used to accommodate the supply lines. It is therefore no longer necessary for the chassis area itself to have such free installation space that the supply lines can be laid without further ado.
- the bulging stiffeners protrude from a main plane of the floor plate in the direction of a floor of an interior of the rail vehicle.
- the free inner spaces of the bulging strips are accessible from below, so that the laying of supply lines can take place in a simple manner.
- the bulge stiffeners can be U-shaped and have horizon tal bearing surfaces. This results in a stiffening of the single-shell base plate and a de-defined support level for other components of the rail vehicle.
- the floor of the interior of the rail vehicle which can in particular be a vehicle for passenger transport purposes, is preferably supported on the bearing surfaces of the bulging strips.
- the term "floor” is to be understood broadly, that is to say, multi-layer floor structures are also meant here, which may also include insulating layers.
- the floor of the interior of the rail vehicle can be glued directly to the bearing surfaces.
- the undercarriage can have a central longitudinal beam in the chassis area, to which sections of the single-shell base plate adjoin on both sides in the transverse direction of the undercarriage.
- the base plate is formed in two parts in the transverse direction.
- Each section of the single-shell floor slab can be equipped with several bulging stiffeners running in the longitudinal direction of the underframe.
- the sides of the sections of the single-shell base plate that are remote from the central longitudinal support can be supported by sliding seats on external longitudinal supports of the underframe.
- Figure 1 is a cross-sectional view of an underframe of a
- Figure 2 is a view from below of the subframe of Fi gur 1 in the area of a main cross member of the subframe.
- a longitudinal section of a subframe of a rail vehicle for passenger or goods transport purposes in its chassis area has a central longitudinal beam 1 and two outer longitudinal beams 2, all of which can be in the form of extruded aluminum profiles and a single-shell base plate 3 made of aluminum sheet wear.
- the base plate 3 is in the transverse direction of the underframe in two sections, each of which extends from the Mittellangträ ger 1 in the direction of one of the two outer longitudinal members 2.
- the sides of the sections of the base plate 3 that are remote from the central longitudinal members 1 are connected to the associated outer longitudinal members 2 via intermediate profiles 4.
- the intermediate profiles 4 and associated sides of the outer side rails 2 form sliding seats, so that any width tolerances of the rail vehicle can be compensated for.
- the nursinglangträ ger 1 the sections of the base plate 3, the intermediate profiles 4 and the outer side rails 2 are each joined together by welded joints from the center outwards.
- the base plate 3 is equipped with a total of four U-shaped bulging strips 5, which protrude upwards from a main plane of the single-shell base plate 3.
- the base plate 3 can be present, for example, as a reshaped aluminum sheet.
- the bulging strips 5 define an essentially rectangular interior space with upper bearing surfaces 6.
- the bulging strips 5 are accessible from their open side at the bottom.
- Electrical and / or pneumatic supply lines 7 are mounted in their respective interior spaces, for example by means of suitable holders.
- a floor 8 of an interior of the rail vehicle is supported on the bearing surfaces 6 and glued directly to them.
- the subframe comprises a main cross member 9, on which a chassis / bogie of the rail vehicle is to be mounted.
- a main air line / main air reservoir line (HBL) 10 as an example of one of the supply lines 7 is passed through the main cross member 9.
- a line 11, also as an example of one of the supply lines 7, for supplying compressed air to an air spring of the chassis from a volume of additional air is connected to the main cross member 9.
- An interior of the main cross member 8 serves as a compressed air container and the main cross member 8 shows connection surfaces 12 for air springs which extend from the connection surfaces 12 downwards.
- the lines 10 and 11 are also laid in the buckling strips 5.
