Definitions
- the invention relates to a car body for a vehicle for passenger transport, with a car body shell that has side walls provided with door and/or window cutouts, a roof and end walls that are constructed from metal structures.
- a car body of a rail vehicle for passenger transport is currently made of aluminum or steel, specifically in varying designs, such as integral, differential and hybrid design.
- the closed structure of such a car body has similar properties to the well-known Faraday cage in terms of its penetration with radio waves, i . H . transmission of radio waves is very low.
- the transmission/reception properties of mobile radio-based communication devices such as mobile phones, laptops, tablets, etc. a. m . , inside a rail vehicle are significantly worse than outside .
- window panes that are particularly permeable to mobile radio frequencies have been developed. This significantly improves the transmission of mobile radio waves through the vehicle window, although these advantages are limited to the immediate window area of the vehicle. Proceeding from this, the invention is based on the object of further developing a car body of the type mentioned at the outset in such a way that it has improved overall transmission for mobile radio waves.
- the car body shell has wall segments which are formed from material which is permeable to mobile radio frequencies (frequency f>700 MHz) and are inserted in openings in the metal structures.
- the planned wall segments of the car body shell which are permeable to mobile radio frequencies, improve the overall transmission behavior of the fully developed car body considerably.
- the car body which is particularly permeable to mobile radio frequencies
- windows that are otherwise optimized for mobile phone reception could be replaced with standard glass windows, for example.
- the car body, which is particularly permeable to mobile radio frequencies to be equipped with windows designed to be optimized for mobile radio reception, so that mobile radio reception is improved in the entire car body or in parts of it where these windows cannot be installed. Because there are also areas of the car in which no windows can be installed nearby.
- Windows that are designed to be particularly permeable for mobile radio reception are particularly favorable for the reception of mobile radio transmitters located to the side.
- the car body presented here could, for example, also enable the reception/permeability of mobile phone radiation by designing the vehicle roof appropriately upwards.
- the selection of the materials depends on the respective attenuation properties for mobile radio frequencies. In Germany, for example, frequencies are required for the LTE standard Frequency bands in the 800 MHz, 1.8 Hz, 2 GHz and 2.6 GHz ranges are common. Frequency bands at 700 MHz, 3.4 to 3.8 GHz are planned for the upcoming 5 G standard.
- the metal structures can preferably be in the form of extruded profiles (integral construction) or sandwich panels.
- the openings provided, into which the wall segments made of material that is permeable to mobile radio frequencies are to be inserted, can be dimensioned so large that they cover several extruded profiles adjoining one another, for example in the vertical direction of a side wall.
- a side wall of a rail vehicle can typically comprise five extruded profiles, which are each aligned in the longitudinal direction of the rail vehicle and arranged vertically one above the other, with adjacent extruded profiles z. B. are joined together by welding.
- the wall segments of the car body shell that are permeable to mobile radio radiation are preferably each embedded in a self-supporting support structure.
- This self-supporting supporting structure is formed, for example, in that suitably positioned openings are created in the all-metal structures, such as extruded profiles or sandwich panels. This can be realized, for example, by milling.
- the wall segments made of material that is permeable to mobile radio frequencies are inserted into the openings created in this way.
- the self-supporting support structure can comprise strut-shaped support structure elements. These result, for example, from the residues of the metal structures remaining after milling.
- a strut-shaped support structure element can be formed from longitudinal sections of extruded profiles that are vertically adjacent to one another and remain after milling or a strut-shaped piece of a sandwich panel. It can be provided in particular that the support structure is at least partially embodied in the manner of a lattice.
- the self-supporting support structure preferably includes corner areas of the door and/or window sections.
- the wall segments made of material that is permeable to mobile radio frequencies should only be arranged in areas of the side walls, the roof and the end walls that are subjected to low static loads. To put it the other way round, it is considered favorable that the corner areas of the door and/or window cutouts, which are subject to particularly high static loads, are integrated into the self-supporting support structure.
- the wall segments made of material that is permeable to mobile radio frequencies are arranged at a distance from, in particular, corner areas of the door and/or window cutouts.
- the wall segments made of material that is permeable to mobile radio frequencies should occupy at least 20% of the side wall, the end wall or the roof of the car body shell.
- the quotient of a partial outer skin area, formed from the sum of the outer skin areas of the wall segments made of material permeable to mobile radio frequencies, and a total outer skin area, including window and door areas as well as outer skin areas of the wall segments, can be used as a basis for calculating such a proportion of the area , are used .
- the surface area of the wall segments should be dimensioned in such a way that the desired transmission is achieved for the entire car body. If sufficient, the surface area can consequently fall below the value of 20%.
- the material that is permeable to mobile radio frequencies is preferably metal-free in order to obtain the desired, favorable transmission properties.
- the material to be used can be selected from the group comprising glass fiber reinforced plastic (GRP) and carbon fiber reinforced plastic (CRP).
- GRP glass fiber reinforced plastic
- CPP carbon fiber reinforced plastic
- Figure 1 is a schematic, perspective view of a longitudinal section of a car body shell for a rail vehicle
- FIG. 2 shows a schematic view of a side wall section of the car body shell for a rail vehicle according to FIG. l .
- the side wall 2 and roof 3 of which are constructed from extruded profiles (aluminum) which run in the longitudinal direction of the rail vehicle carriage and are welded to one another.
- the side wall 2 of the car body shell 1 is equipped with window cutouts 4 in a conventional manner.
- door openings can be provided in particular at the ends of the carriage.
- Wall segments 5 of the car body shell 1 are made of glass fiber reinforced plastic and are used in associated openings in the metal support structure.
- the outer skin area of the wall segments 5 takes up at least 20% of the total outer skin area of the side wall 2 .
- the openings for receiving the wall segments 5 of the car body shell 1 are at the production of the car body shell 1 has been formed by milling. This can be done, for example, in one step with the creation of the required door and/or window cutouts 4 . From this processing of the initially all-metal car body shell 1, a metal support structure is created, which is built up from the longitudinal pieces of the individual extruded profiles 6 (cf. FIG. 2) that remain after the milling process.
- the metal support structure is in the form of strut-like lower support structure elements 7 and upper support structure elements 8 .
- FIG. 2 shows a longitudinal section of the side wall 2 . It is illustrated that the window cutouts 4 are each bordered by metallic material. Lower strut-shaped elements 7 are arranged in such a way that they encompass lower corner areas of the window sections 4 .
- the lower support structure elements 7 extend approximately from a point on the lower edge of the side wall 2, which is located approximately in the middle below a window section 4, obliquely upwards in the direction of a lower corner area of the associated window section 4 and from there further until again over the entire Height of the side wall 2 full-metal area 9 of the side wall 2 or a full-metal area 10 arranged between two adjacent window openings 4 is reached.
- Upper supporting structure elements 8 adjoin the upper ends of the lower supporting structure elements 7 , run in the direction of the upper corner regions of the window sections 4 and end at the upper edge of the side wall 2 .
- the wall segments 5 made of glass fiber reinforced plastic.
- the wall segments 5 close laterally and removed from the corners of the window sections 4 or are of the Framed supporting structure elements 7, 8 and full-metal areas of the side wall 2.
- the partial areas 5 of the car body shell 1 are connected to adjoining metal structures, such as the supporting structure elements 7, 8, the full-metal areas framing the window sections 4 and the areas 9, 10, for example by means of adhesive bonds.
- adjoining metal structures such as the supporting structure elements 7, 8, the full-metal areas framing the window sections 4 and the areas 9, 10, for example by means of adhesive bonds.
- screw connections for fastening the wall segments 5 to adjacent metal structures of the type mentioned.
- the strut-shaped support structure elements 7 , 8 can also be formed from sandwich panel structures that remain after milling, for example. Sandwich panels with two metal cover layers and a honeycomb structure between these cover layers, which is also made of metal, are used to build up side, front and other walls.
- strut-shaped support structure elements 7, 8 are formed from individual profiles and the construction of the car body shell includes such individual profiles, sandwich panels and/or extruded profiles that are suitably joined together.
