Description

Passenger transport vehicle The present invention relates to a passenger transport vehicle, particularly a railway vehicle, such as a tram car or the like, which has a body, 5 on which a superstructure has been fixed on longitudinal side walls. of roof. In passenger transport vehicles it is generally known to close on the upper part the body that houses the persons to be transported by a roof structure, which is fixed on the longitudinal side walls. For this purpose, a roof closing plate is usually fixed and permanently sealed by means of welding or rivets along its peripheral outer edge on the remaining structure of the body. In this case, a considerable supply of tensioning and straightening is present in the manufacturing process and further measures are necessary to provide channels for ventilation and evacuation of air, for the cables, as well as for acoustic and thermal insulation. The present invention has the purpose of providing measures 0 for a passenger transport vehicle as described above, by which manufacture and assembly can be carried out more easily.

The solution of said purpose takes place in accordance with the present invention by means of a passenger transport vehicle of the initially mentioned type, which is characterized in that in the region of the upper lateral edges of the longitudinal side walls have been fixed respective longitudinal beams carrying of roof, which are mutually facing each other with at least one wing approximately horizontally and a roof plate provided with channels integrated by mutually opposite longitudinal edges on the free ends of said wings in a weld-free and sealed manner. In order to provide a roof structure integrating different functions, longitudinal carrier beams fixed by the upper lateral edges of the longitudinal side walls of the body as a support for a prefabricated plate are used in a construction of a passenger transport vehicle according to the present invention. roof, which is materialized as a self-supporting component and provided with channels, in which the air flow necessary for the admission and evacuation of air from the interior of the bodywork can be conducted and / or electrical, hydraulic or electrical conduits can be housed supply or control tires. The channels used for ventilation and evacuation of air have open openings to the passenger compartment and are communicated in other wall segments through openings with the outside environment or with an air conditioning equipment provided with at least u fan. The channels used for supplying fresh air are arranged in the central or outer area of the roof plate and have air intake pipes which face the passenger compartment and pass a roof covering. The other channels, which are located in particular on the longitudinal or lateral longitudinal side edges and which serve for the evacuation of air, on the contrary draw the exhaust air leaving the passenger compartment in the area of the windows or the side walls and they direct that air directly to the outside environment. While the channels serving the supply of fresh air are closed by their front faces, the openings adjacent to the channels serving as exit air conduits are mutually communicated at the front ends, in each case through a channel Transverse salt, from which the exhaust air can flow through a large section opening to the outside. For the feeding of the channels used for the air intake, an air conditioning unit can be placed above the ceiling plate., which has at least one fan for the air supply, possibly also an air conditioning unit, and which drives the intake air particularly towards the central channels of the ceiling plate. The air conditioning equipment is preferably supported on longitudinal load-bearing profiled ribs, which extend in the longitudinal direction of the car parallel to the lateral longitudinal edges of the roof plate and which are profiled in an upward part of the beams longitudinal carriers fixed to the longitudinal side walls. The air conditioner, however, can also be fixed directly on the ceiling plate. The longitudinal load-bearing profiled ribs increase the rigidity of the longitudinal load-bearing beams, the space between said longitudinal load-bearing ribs being used to receive the roof plate. The air conditioner immediately above said ceiling plate can be communicated via connection sockets simply placed through congruent openings provided in the upper outer wall of the roof plate with the air transport arrangement. The air intake pipes of the corresponding channels, which are directed downwards towards the passenger compartment, are covered inside the passenger compartment preferably by an air deflector screen, in which a lighting equipment that is covered is integrated. turn with the air deflector screen. In the area between said air intake pipes, preferably in the roof plate there is a receiving groove open on one side towards the luminaire, in which electric supply and control conductors are preferably laid. It is particularly advantageous to produce the ceiling plate from plastic, the outer wall being able, in particular, to have a greater thermal insulation than the inner wall, which can be materialized by the thickness of the material or the selection of the material. The ceiling plate can also be formed as a "sandwich-type" composite plate of several sheets, with integrated channels running in the longitudinal or transverse direction. The roof plate, which only seats on its outer marginal edge on the free ends of the longitudinal supporting beams, can also be additionally supported by transverse trusses, which extend from one longitudinal supporting beam to the other and which they are fixed to said beams or to the corresponding side wall. The ceiling plate can be manufactured as an extruded part in a plastic injection process or it can be manufactured with a sandwich-like structure from two plates with vertical partitions to form the channels. For this purpose, additional profiles can also be formed by molding, which can be used to fix equipment, tubes and the like. The roof plate can be preassembled with the corresponding equipment and installation means independent of the body and must only be lifted by means of a crane on the prepared vehicle and fixed by interposing a sealing means along the outer edge of the support on longitudinal beams. In this case, no further adjustment work is necessary. The sealing means may also be constituted by an elastomeric seal or the like, or by an adhesive, in particular of permanent elasticity. The filling takes place in an exactly defined interface area and consequently can be carried out without difficulties. The present invention is described in more detail below on the basis of a cross-sectional representation of the roof area of a body of a passenger transport vehicle. From a passenger transport vehicle materialized as an example as a tram, only the upper sections of exterior longitudinal side walls 1, at least substantially vertical, in which windows 2 are provided have been illustrated. The longitudinal side walls 1 are constituted by two sheets and provided with support elements, thermal insulation and insulation acoustics disposed between said sheets, presenting a metallic outer sheet of wall. In the area of the upper lateral edges of the longitudinal side walls 1, an angled longitudinal supporting beam 3 is fixed in each case. An at least substantially horizontal wing of each supporting beam is directed towards the longitudinal center of the vehicle. The light between the mutually opposite longitudinal edges 4 of the horizontal wings of the supporting beams 3 is bridged by means of a roof plate 5 constituted in the manner of an independent constructive unit, which extends in the direction of the longitudinal axis of the body. , resting only with its outer longitudinal edges in a hermetic manner on the mutually opposite free ends 3a of the corresponding wings. As a sealing means, a rope, sealing strip or the like can be placed between the longitudinal edges and the free ends 3a of the supporting beams, although a permanent elastic adhesive can also be applied as a sealing means. The ceiling plate 5 is fastened with the respective supporting beams 3 by means of conventional tensioning means. In this way, the roof plate 5 is fixed in a weld-free manner and is airtight to the longitudinal supporting beams 3. The roof plate 5 can be manufactured particularly in one piece in the manner of an extrusion-pressed profile, being provided with a plurality of channels 6, 7, which in the assembly position run horizontally side by side in the longitudinal direction. At least two of said channels 6, 7, preferably the four channels illustrated, are embodied as air ducting channels and each have at least one through opening 8, 9, which open towards the passenger compartment 10 provided in the interior of the body. The two inner channels 6 which serve as air intake ducts have in their respective passage opening 8 an air intake pipe 12 which passes through the roof lining 11 of the car interior 10, having been arranged with respect to these in the enclosure 10 in front of its air intake openings juxtaposed relatively narrowly a common air baffle screen 13 with integrated lighting equipment 14. Between the air intake pipes 12 or the corresponding channels 6, it is provided in a core of separation of the ceiling plate 5 a receiving groove 15 open towards the lighting device 14, in which electrical conductors 16 are preferably laid, as an example for the power supply and control of the lighting equipment 14. From inside the enclosure 10 of the passenger compartment the stale air can flow as indicated by arrows 17 to mode example in the area of the window 2 through the side walls 1 behind the roof lining 11 and from there through the through openings 9 to the additional channels 7 which serve as air evacuation ducts in the plate 5. The channels 6 that serve as air intake ducts are sealed longitudinally at their both ends and have on the outer wall 18 of the roof plate 5 respective openings 19, which are connected through connection pipes with a air conduction system of an air conditioner 20 disposed immediately above the roof plate 5. The air conditioner 20 supplies air conditioning as indicated by arrows 21 to the enclosure 10. The other channels 7, which are located externally, can be open longitudinally at both ends and are communicated in each case by the front faces through a transverse channel, from which the stale air can escape towards the outside.

To secure the air conditioner 20, both longitudinal support beams 3 are provided in the area of the free wing ends 3a longitudinal profiled ribs 3b formed in one piece, which extend longitudinally to the roof plate pair 5 and on which the air conditioning equipment 20 is seated, which extends over the entire width of the roof plate 5. Said longitudinal load-bearing ribs 3b also provide a reinforcement of the longitudinal load-bearing beams 3 and the space required in height to house the roof plate 5. To brace the horizontal wings 3a, 3b of the longitudinal beams 3, as well as the roof plate 5, and to increase the stability of the body, transverse trusses 22 are provided which are fixed on those wings of the longitudinal beams 3, which run downwards, or directly on the respective longitudinal side walls 1, ext. said trusses being provided from a longitudinal side wall 1 towards the other longitudinal side wall 1. To provide the outer wall 18 of the roof plate 5 with better characteristics of acoustic attenuation and thermal insulation, its thickness of material is greater than the interior wall. 23 of the roof plate 5, which runs parallel with respect to said outer upper wall 18. In the case that the roof plate 5 has sufficient rigidity and load capacity, the transverse trusses 22 can be dispensed with. so that the inner wall of the roof plate 5 can simultaneously constitute the visible roof wall of the passenger compartment. The transverse trusses can also be integrated in particular in the roof plate 5 between its inner and outer walls to achieve the same effect, the channels 6, 7 also being able to be oriented in the transverse direction with respect to the longitudinal direction of the bodywork. The ceiling plate 5 can also be manufactured in the manner of a composite plate (sandwich) consisting of two originally independent inner and outer walls, between which vertical partitions are interposed to define and laterally close the integrated channels, said partition walls being fixed to the interior and exterior walls. In this case, the outer wall can be constituted by a material with particularly high acoustic attenuation and thermal insulation characteristics. In addition, in each case between a wing 3b of the longitudinal profile and an imaginary plane defined approximately by the longitudinal side wall 1, a cable channel 23, 24, in which electric cables 25 are laid for control and power supply purposes, are provided. 24 Volts and on the other hand cables 26 for a consumer of 600 Volts. The outer wall 27 of the cable channels 23, 24 is preferably in the plane defined by the longitudinal side wall 1 and together they serve with extensions 28 that extend upwards to cover the upper structures 3b, 5, 20 of the roof. It is also possible to provide air intake channels that are located externally and apparatus housings on the ceiling plate.
