Description

Car body for a rail vehicle and method for its production

The invention relates to a car body for a rail vehicle, in particular for a high-speed train, wherein the car body has a bottom and side walls which extend on opposite sides of the floor upwards and wherein the bottom and the side walls of an interior of the car body for the transport of persons and / or limit goods. The invention further relates to a rail vehicle with such a car body, a method for producing the car body and a method for producing the rail vehicle.

The operation of rail vehicles requires a variety of equipment, such as a voltage transformer, control devices for controlling other equipment, containers for liquids, pumps for liquids, brake system equipment and electrical distributors. These devices are mainly used in cars for

High-speed trains arranged at the bottom of the floor. For example, DE 19949243 C1 discloses that the floor construction is on its underside

Has recordings for attachment of adapter elements. The adapter elements are designed for fastening a profile frame. The profile frame consists of

Frame segments, which are formed with means for fastening underfloor units and equipment. The devices are hung on the profile frame.

Underfloor (i.e., below the floor of the car body) arranged devices can be different in weight. For example, a voltage transformer may weigh several tons while an electric distributor weighs only a few kilograms. To the

The weight of the car should not be compromised if, for example, all the heavy equipment in the front of the wagon and all light equipment in the rear of the wagon should not be located. Also in the direction transverse to the direction of travel, the particularly heavy equipment should be located with its center of gravity in the middle of the car body and should be as possible, the center of gravity of the underfloor devices located in the middle of the car body. Since the devices but also have very different volumes and are to be connected, for example, to cables or liquid lines, the mounting location for the individual devices can not be chosen freely. In many cases, at least one particular local area for housing a particular device must be respected, or additional leads must be provided or cables are accepted. In addition, the production of

Connections of the devices is difficult directly below the bottom of the car body. In the production of the car, the assembly can be facilitated by the fact that the devices are first attached and connected in the underfloor area and only then other facilities and parts of the car are mounted. In the later maintenance and repair of equipment, however, the effort for loosening and restoring the connections and disassembly of the devices is difficult. In addition, even the arrangement of particularly heavy equipment below the ground contributes to the fact that the overall center of gravity of the car is above the rails. With a bracket on the underside of the floor, which allows a lower arrangement of heavy equipment, the center of gravity can be lowered. However, such a stable additional bracket increases the overall weight of the car.

It is an object of the present invention to provide a carbody

Rail vehicle with a car body, a method of manufacturing the

Specify car body and a method of manufacturing a rail vehicle with the car body, which facilitate the assembly of underfloor devices, do not lead to a significant increase in the total weight, with respect to the position of the devices below the ground open up choices and a low position of the overall center of gravity of the Allow the car.

It is proposed to arrange under the floor of the car body at least one underbody support which extends from one side of the car body to the other side, leaving a space between the support and the floor for accommodating at least one device. Under the sides of the car body, between which extends the underbody support, are understood in the direction of travel left and right sides on which the side walls of the

Car body are located.

In particular, the underbody support may take a U-shaped course from one side to the opposite side. At its ends, ie at the sides of the car body, the underbody support is connected to supporting parts of the car body, in particular each with a longitudinal member of the car body, which serves to transmit longitudinal forces in the longitudinal direction of the car body. Such side members are usually located in the transition region between the ground and the side walls. In particular, in the manufacture of the carbody according to the present invention, first the floor is connected to the side rails, the underfloor structure is mounted and thereafter the side walls are joined to the floorboards

Longitudinal beams connected. The attachment of the underbody support to supporting parts of the carbody allows the weight of at least one of the devices placed underfloor to rest on the underbody support, or at least the weight of the device partially, preferably predominantly, and most preferably completely on the underbody Carrier is exercised. In a simple embodiment, a device is placed directly on the underbody support so that it is in the space between the underbody support and the floor of the carbody, i. in the case of a U-shaped beam in the area of

Querschenkels of the U is arranged. Due to the small height of the space below the floor of a car body to the track bed and due to the usually larger width of a rail vehicle, the transverse leg of the U is usually longer than the two longitudinal legs.

The invention is based on the recognition that a subfloor support can be made very stable at a relatively low weight, so that it can absorb weight forces from underfloor devices to be arranged. In addition, such a

Underbody support in a simple manner with supporting parts, in particular the side rails, are fixed in the transition region between the bottom and side walls. This makes it possible in a simple way to derive the weight forces directly on the underbody support and the supporting parts on the bogies.

The attachment of the underfloor devices directly to the underbody support, preferably at its lowest point or in the low-lying area at a distance from the floor of the car body, leads to a low center of gravity of the car.

In addition, the production of connections to the devices is facilitated because the

Connecting cables and connecting cables usually pass through the floor or are guided on the underside of the floor. Between devices that do not extend over the entire height of the space between the underbody support and the floor of the car body, a gap remains to the ground, so that the mounting of the terminals is facilitated. In addition, the underbody support does not require that a device be attached to a particular position in the course of the wearer. The exact position can therefore be selected taking into account other criteria. This is especially true when not only an underbody carrier, but at least two such carriers are present. In this case, additional elements may be provided which, together with the subfloor beams parts of a

Substructure are. Such elements will be discussed in more detail. Depending on the design of these elements, the underfloor devices can optionally be attached to the additional elements of the substructure or arranged thereon. If there are a plurality of underbody beams, it is preferred that the space between the beams at least partially by preferably

plate-shaped elements is closed. For example, such a plate-shaped element may form a subfloor, which preferably extends in the horizontal direction and approximately parallel to the actual bottom of the car body. Alternatively or additionally, a plate-shaped element may form a side wall of the underfloor area. These plate-shaped elements between the underbody supports improve the

aerodynamic characteristics of the car.

In particular, the following is proposed: a car body for a railway vehicle, in particular for a high-speed train, the car body having a bottom and side walls extending upwards on opposite sides of the floor and wherein the bottom and the side walls form an interior of the car body for the transport of Persons and / or goods limit, wherein in each case a longitudinal support for transmitting longitudinal forces is in a transition region between the bottom and the side walls, which extends in the longitudinal direction of the car body and wherein the car body has at least one underbody support, which extends below the bottom extending from the one longitudinal member to the other side member, wherein the underbody support extends partially at a distance from the ground, so that between the underbody support and the floor a space for receiving at least one device for the operation of

Rail vehicle is formed, wherein the weight of the device acts on the underbody support.

The space between the side walls and the floor, which is usually also bounded above by a roof, is the space for transporting persons and / or goods (for example, merchandise). In contrast, the underfloor devices to be arranged below the floor of this transport space are to be arranged. The bottom of the transport space, which is also the bottom of the car body, which is a carrying structure, is usually some 10 cm up to 1, 5 m above the height level of the rails of the vehicle. With the ground usually also the bogies are connected, via which the car body is supported on the rails. In contrast, the at least one underbody carrier has the function to absorb loads of underfloor devices and to initiate the corresponding forces in the car body, in particular in the side members.

Preferably, the underbody support initially extends downwardly from the side rail and is at a lower level than the level

Height level of the side members angled or curved, wherein the underbody support merges at the bend or bend in an approximately horizontal portion extending in the distance to the bottom of the car body. On the opposite side is preferably again a bend or bend, at which the underbody carrier merges into a second, likewise from top to bottom or from bottom to top extending portion. With respect to a median plane which extends in the vertical direction and also extends in the longitudinal direction of the car body, the underbody support is preferably symmetrical, or at least substantially symmetrical, that is, symmetrical with the exception of

Fasteners with which the carrier is connected to the side members and / or the underfloor devices.

The above-mentioned plate-shaped elements, which serve the lining of the space below the carbody floor and connect the longitudinally adjacent subfloor support, preferably not only have the function of covering the room, but preferably also serve the mutual support of the adjacent subfloor Carrier in the longitudinal direction of the car body and in directions that run diagonally. This creates an underbody construction that is inherently stable. Also, it is made possible in this way to arrange the underfloor devices anywhere on the interior of the underbody construction and optionally connect to one of the underbody support and the plate-shaped elements and / or to arrange on the plate-shaped elements. The plate-shaped elements are preferably coupled via a frictional connection to the underbody carrier. The plate-shaped elements may in particular be extruded

Disc-shaped elements act in which a plurality of air chambers is arranged between two sheet-shaped, approximately parallel regions forming the outer surfaces, which are separated by partitions which extend in a longitudinal direction of the plate-shaped member. Such extruded plate-shaped elements may preferably be made of aluminum and are preferably bolted to underbody beams. In this case, a plurality of plate-shaped elements can be manufactured separately in the extrusion process and connected to each other before assembly to the underbody beams, in particular welded. Also, the side walls and the bottom of the car body may be at least partially made of such plate-shaped elements. If the side walls, the floor and an additional ceiling element are prefabricated, substantially plate-shaped elements, it is referred to an integral construction of the car body. The underbody beams are particularly suitable for such a car body, wherein also longitudinal beams can be made in the transition region between the bottom and the side walls in the extrusion process. However, other constructions are possible, in particular with the side members, for example conventional double T-beams, i. I-beams.

A guide is preferably arranged on the longitudinal carriers, by means of which a movement of one end of the underbody carrier can be guided in the longitudinal direction of the vehicle body. There is provided a fastening means by which the underbody support is selectively attachable in a plurality of different positions relative to the side rail. This makes it possible, during the first assembly of the car body or in a later remodeling, to move and fix the substructure supports in the longitudinal direction of the car body. This allows different configurations of underfloor devices to be attached to the underbody construction. Depending on the dimensions and weight of the underfloor units, the positions of the underfloor supports can be selected and adjusted. The guide can be realized for example by one or more downwardly open C-shaped rails. Alternatively, however, the upper ends of the underbody beams may be attached to another substructure mounted on the underside of the floor.

As already mentioned, a plurality of the underbody beams can be arranged in different longitudinal positions in the longitudinal direction of the car body and extends each below the bottom of the one longitudinal carrier to the other side member. For example, 5-8 such carriers may be disposed below the floor of a large capacity passenger car to accommodate the underfloor devices required for the operation of the car or train. In this case, preferably all sub-floor beams are located in the longitudinal section between the two bogies of the

Car. However, it is also not excluded to accommodate one or two underbody beams in the end region of the car body, that is, at the longitudinal ends of the car body. However, there is usually the clutch for coupling the car with an adjacent car, so that the space available for the underfloor devices is small.

At least two in the longitudinal direction of the car body adjacent subfloor support may be connected to each other by at least one longitudinal strut. The longitudinal strut does not have to run exactly in the longitudinal direction of the car body, but can also run diagonally. The use of longitudinal struts represents an alternative or additional measure to the use of plate-shaped connections (also referred to above as plate-shaped elements), which serve to stiffen the underbody construction. For example, if no rigid plate-like elements are used, but several longitudinal struts, the substructure can be made very stiff and light and, for example, clad only with thin, non-load-bearing elements to improve the aerodynamic properties. Several such longitudinal struts result in a distribution of the weight forces exerted by the underfloor devices, so that such a construction is particularly advantageous when underfloor devices with very different weights are to be accommodated below the floor.

It is preferred that at least one of the plate-shaped elements, more preferably all plate-shaped elements which form a lateral lining of the underbody space, have an opening closed by a flap, wherein the flaps can be unfolded as required to gain access to the underbody. To get space.

In particular, in the end region of the underbody construction, for example in the vicinity of a bogie, an underbody support may be supported by an additional support on the floor of the car body and / or on one of the side members. In this case, for example, at least one elongated support may extend diagonally in the direction of travel from the low-lying region of the underbody support to the floor or side member. Such support stabilizes the underbody construction. For example, it can be prevented in this way that in an impact of the rail vehicle in the longitudinal direction, the underbody construction kinks due to their inertia and thus items from the underbody space

be thrown out or even the entire underbody construction moves independently in the direction of travel.

Depending on the loading condition of the car body, the car body can bend down slightly. This deformation forces are applied to the underbody construction. Preferably, the underbody beams and the additional elements of the construction are designed and interconnected such that the

Underbody construction can also be deformed. To make this possible, for example, the additional support and / or a fastening connection between the underbody support and the additional support is configured elastically deformable.

Such elastic configuration can also for the connection of two in

The longitudinal direction of adjacent subfloor carrier be chosen or for a

Fastening connection between a connection (for example, a side member and an underbody support).

The scope of the invention also includes a rail vehicle with a car body in one of the embodiments described or to be described. In this case, at least one device which serves to operate the rail vehicle is arranged in the space between the underbody support and the floor. The device exerts its entire weight directly or indirectly on the underbody support. In particular, the device is from above on the underbody support and / or construction element of

Underfloor construction made, the two adjacent or more subfloor support interconnect (for example, plate-shaped elements and / or longitudinal struts). In contrast to previously known solutions, the devices are therefore not suspended below the floor of the car body, but below the ground on the

Subfloor construction provided. Advantages of this solution, in particular its flexibility and ease of maintenance, have already been mentioned. Furthermore, the scope of the invention includes a method for producing a

Car body for a rail vehicle, in particular a car body for a high-speed train, comprising the following steps:

Providing a floor and two side members,

• connecting the longitudinal members to the ground,

• Attaching an underbody support to the side rails such that the underbody support extends below the bottom from one side rail to the other side rail and between the bottom rail and the floor there is a space for receiving at least one device for operating the rail

Railway vehicle is formed,

Providing two side walls,

Connecting the floor to the side walls so that the side walls extend upwardly from the floor and so that the floor and sidewalls define an interior of the car body for the transport of persons and / or goods, each being in a transitional area between the floor Floor and the side walls of one of the longitudinal beams for transmitting longitudinal forces in the longitudinal direction of the car body extends,

The side members are preferably provided so as to extend in the longitudinal direction of the carbody to be manufactured. The above steps do not have to be done or not all in this order. Therefore, the above listing does not mean an order of execution of the steps. Although initially the side members and the underbody support must be present so that they can be connected to each other. However, it is e.g. It is possible to connect the floor to the side rails only then or to finish the floor only when the side members and the underbody support are already connected to each other. Also, it is not mandatory that the side walls are then connected via the side members to the ground. This step can also be carried out before the connection of the side members to the underbody support.

Embodiments of the method and its advantages will become apparent from the description of the car body and the rail vehicle. In one embodiment of the method, for example, not only the car body but the entire rail vehicle is manufactured, wherein in the space between the underbody support and the ground at least one device is arranged for the operation of the rail vehicle, so that the device exerts its entire weight directly or indirectly on the underbody support.

The underfloor devices may be, for example, tanks for liquids, pumps for liquids, power distributors and electrical and electronic control devices, as well as brake modules, transformers and other control devices.

Particularly heavy equipment, such as the main transformer of a

Drive means for driving the rail vehicle may, unlike the basic concept of supporting the equipment on the underbody beams, be hung on the floor of the car body. As a result, the substructure, which is formed by the at least one underbody support and possibly other elements, not so stable and difficult to be designed that it also carries this particularly heavy device.

The upper ends of the underbody beams are preferably made longer in the longitudinal direction of the car body than the longitudinal extent of the carrier in its course from one side of the car body to the other. Due to this wider configuration of the end portions of the carrier when attached to the bottom of the

Car body or on the side member in addition to a kinking in

Reinforced longitudinal direction and secured. For example, in this end region so-called gusset plates may be arranged in which a plurality of

Through holes located through which screws or bolts can be performed with which the carrier at the bottom or the side rails of the

Car body is attached. An embodiment will be discussed in more detail.

Embodiments of the invention will now be described with reference to the attached

12 shows the arrangement according to FIG. 10 in a three-dimensional representation, the view being directed at the underside of the arrangement.

Fig. 1 shows a single underbody support 1, which has a U-shaped profile, wherein the transverse leg 4 is designed to be significantly longer than the longitudinal leg 2a, 2b extending in the vertical direction. At the top of the first

Longitudinal limb 2a and also at the upper end of the second longitudinal limb 2b, both of which extend approximately in a vertical direction, only slightly inclined inwardly from top to bottom, there is in each case a T-shaped widening 5a, 5b, in a plate-shaped mounting surface opens, which each have a plurality of

Through holes 6, of which only a few are denoted by these reference numerals in Fig. 1. In order to increase the stability of the carrier 1 in the region of the transition between the longitudinal limbs 2 and the transverse limb 4, a diagonal brace 3a, 3b which connects a central region of the longitudinal limb 2 with the transverse limb 4 diagonally is located in the transition region. The term

Longitudinal does not refer to the longitudinal direction of the car body.

In the upper region of the longitudinal limbs 2, an additional support 9a, 9b is optionally attached, in each case on the inside of the longitudinal limb 2, in order to fasten, for example, an additional covering of the carriage body bottom (not shown in FIG. 1).

In the transition region between the longitudinal legs 2 and the transverse leg 4 is in each case a plurality of holes 10 a, 10 b, 10 c, 10 d and that on the left in Fig. 1 pointing to the visible surface and on the in Fig. 1 to the right rear facing not recognizable surface of the carrier 1. These two to the left front and right rear facing surfaces are realized in the said transition region by sheet-like, mutually parallel and spaced-apart material areas of the carrier 1. Therefore, it is also possible in the

Gap between the two material areas, for example one

Hold the screw head or tighten a nut. These holes 10 are used for fastening longitudinal struts, via which the carrier 1 is connected to longitudinally adjacent carriers.

The carrier 1 is made of aluminum, for example. It can be made from a plurality of individual parts. For example, the diagonal strut 3 is manufactured separately and only then connected to the longitudinal strut 2 and the cross member 4. The connection areas are not shown in detail in Fig. 1. However, it is also possible, respectively, the material areas, the left front and right rear pointing

Form surface of the support 1, in one piece and connect to each other by a metal strip which forms the outside surfaces of the longitudinal leg 2 and the downwardly facing surface of the transverse leg 4. Furthermore, a further sheet metal strip can be added later, which is the inside surfaces of the longitudinal leg 2 and the diagonal struts 3 and the upward facing Surface of the transverse leg 4 forms. The required joints are made for example by welding.

There are four additional supports 7a, 7b, 7c, 7d with the surface of the transverse limb 4 pointing to the left in the vertical direction

Holes, wherein such support elements are also arranged on the right side facing the rear side of the transverse leg 4 or at least can be arranged, if it is not the last in the longitudinal direction of the carrier 1. These support elements 7 can be used for laying and connecting with plate-shaped elements or as attachment points for attaching underfloor devices.

The transverse leg 4 also has a plurality of through-holes 8 through which, for example, cables or lines for liquids or gases can be passed. In this way, for example

Connecting cables for underfloor devices are passed through the carrier 1 and thus fixed in places in terms of their position.

Fig. 2 shows the carrier 1 of FIG. 1 with its transverse leg 4 and its

Longitudinal limbs 2a, 2b, wherein the longitudinal legs 2 are fastened on the underside by a respective longitudinal member 24a, 24b of a rail vehicle car body. Of the car body, in addition to the longitudinal members 24, which preferably extend over almost the entire length of the car body (the longitudinal extent extends in a direction perpendicular to the plane of FIG. 2), also a bottom 13 and the lower portions of two side walls 11a, 11th b shown. The bottom 13 is in the

Embodiment composed of five plate-shaped elements 12, which are welded together. In this case, the hollow chamber structure of both the bottom 13 and the longitudinal member 24 can be seen. Preferably, it is extruded aluminum profiles. The roof area not shown in Fig. 2 and the side walls (which are not shown in Fig. 2 except the lower portions) may also be made of extruded aluminum profiles of similar construction.

By a cuboid 15, which is on the transverse leg 4 of the underbody support 1, indicated in Fig. 2 that in the underfloor space between the bottom 13 and the transverse leg 4 underfloor devices can be arranged. Fig. 3 shows an arrangement with a total of eight longitudinally successively arranged underbody beams 101 - 108, for example, all as shown in Fig. 1 and in Fig. 2 are executed. In this case, as shown in FIG. 1, the individual carriers 101 - 108 extend transversely to the longitudinal direction and have a U-shaped profile when viewed in a plane perpendicular to the longitudinal direction.

Between the underbody beams 105 and 106 is located on the

opposite sides in each case an additional strut 110a, 110b, which can be configured similar to the longitudinal struts 2 of the carrier 1 according to FIG. 1 and FIG. However, the additional struts 110 are not connected to the underbody beams 101-108 by a crossbar.

The underbody beams 101 - 108 are connected in pairs on both sides of the car body by a longitudinal strut 121-128 and 131-138 extending in the longitudinal direction of the car body. In the specific embodiment, not only a longitudinal strut is present on each side between the carrier 105 and the carrier 106, but a first longitudinal strut 125 or on the other side 135, which connects the carrier 105 with the additional struts 110, and both Pages a longitudinal strut 126, 136 which connects the additional strut 110 with the carrier 106. The connections of all the longitudinal struts 121-128 and 131-138 are respectively in

Transition region between the running approximately in the vertical direction of the part strut of the carrier and the extending approximately in the horizontal direction of the cross member of the carrier. For fastening the longitudinal strut, for example, those in FIG. 1 are used

For example, threaded rods are introduced with external thread at the front end of a longitudinal strut in the holes 10 and secured on the opposite side of the bore by nuts.

The illustrated in Fig. 3 underbody construction with U-shaped profile underbody beams and longitudinal struts on the opposite sides provides a

Embodiment for a stable construction. However, such longitudinal longitudinal struts are not absolutely necessary. For example, the function of the longitudinal struts can be taken over by correspondingly stably configured plate-shaped elements, which are arranged between the pairs of mutually adjacent underbody beams and connected to the carriers. Another possibility is to carry out the underbody construction in the manner shown in Figure 3 with U-shaped underbody supports and longitudinally extending longitudinal members and additionally to install plate-shaped elements as a panel. Such an embodiment is shown in FIG. The same reference numerals in Fig. 4 as in Fig. 3 denote like elements. On the underside of the U-shaped underbody beams 101-108 are mounted plate-shaped fairings 144a-144h which form the bottom of the underbody space. It is also possible, as shown in the plate-shaped element 144f, that the plate-shaped panels have a cutout 139, so that the underbody space is accessible from below through the cutout 139 or so that an underfloor device for which the height of the underfloor Room is not sufficient or that should not be arranged in a closed space, protrudes. In particular, for the purpose of cooling the underfloor device such a cutout 139 may be useful. The driving wind then cools the bottom of the device. Also, as indicated in the plate-shaped panels 144g, a

air-permeable grille be present in the panel, so that an air exchange is possible.

Furthermore, the side surfaces of the support structure shown in Fig. 4 can be covered with plate-shaped elements 141. In this way, with the exception of the section 139 closed on three sides U-shaped trough is formed, which bounds the underbody space. The plate-shaped elements on the side surfaces preferably each have a flap 140 (as shown in element 141c, 141d, 141e) and / or also a ventilation grille.

On the left in Fig. 4 facing the front end of the construction, two damping elements may be present (not shown), which are connected to the transition region of the carrier 108 between the transverse leg and extending approximately vertically in the longitudinal leg. These damping elements allow a support against an additional not shown in Fig. 4

Supporting device, wherein the damping elements deform elastically under load and thus in particular also allow a deformation of the support structure relative to the additional support.

As indicated on the right side of the lateral panel 141 at one point, the lateral panel 141 may have at least one reclosable opening, for For example, a flap 140 or a door or a removable trim part so that the space within the underbody construction is accessible.

FIG. 5 shows three subfloor beams 101, 102, 103 arranged one after the other in the longitudinal direction (horizontal direction in FIG. 5), for example three of the beams shown in FIGS. 3 and 4. In this case, the carrier 101 shown on the right in FIG. 5 is the last carrier in the longitudinal direction. Similar to the construction according to FIG. 3 and FIG. 4, it is connected via a side member 131 to the adjacent carrier 102, which in turn is connected to the next carrier 103 via a side member 132.

The end support 101 is supported by an additional support 155, 156, 157 on the bottom 13 of the car body. The bottom 13 is designed, for example, as shown in FIG. The additional support has a diagonal strut 155 which extends diagonally upwards from the bottom to the support 101 to the bottom 13 and which at its upper end has a parallel to the floor at its underside

extending longitudinal strut 157 is connected, which is connected at its opposite end to an upper portion of the carrier 101. An additional support strut 156 supports the central region of the diagonal strut 155 against the second end of the longitudinal strut 157.

There are also other such additional Abstützungen conceivable, for example, depending on the design of the diagonal strut 155 no additional support strut 156 may be present. Also, if necessary, the longitudinal strut 157 can be omitted. Preferably, there is an additional support of the end-side support 101 at both

opposite sides of the car body, so for example both

Transition areas of the carrier 101, at which the longitudinal direction extending in the vertical direction strut merges into the transverse strut, which extends in an approximately horizontal direction, are supported against the bottom 13 of the car body.

Fig. 6 shows a stiffener 158, 159, 160 between two adjacent underbody beams 105, 106. Again, the arrangement shown in Fig. 6, for example, may be a part of the arrangement shown in Figs. 3 and 4. In FIG. 6, a total of four underbody beams 104, 105, 106, 107 can be seen one behind the other in the longitudinal direction. Also visible are longitudinal struts 124 between the beams 104, 105 and longitudinal struts 127 between the beams 106, 107 and the floor 13 of the car body recognizable. The stiffener has a frame 158, the frame element extending in the vertical direction are arranged on the likewise longitudinally extending longitudinal struts of the carrier 105 or 106. At the bottom and at the top of the beams 105, 106 respectively, a longitudinal strut of the frame 158, which extends in the longitudinal direction (horizontal direction in Fig. 6) of the rail vehicle or car body. In addition, the frame 158 is stiffened by two crossing diagonal struts 159, 160.

This creates a very stable construction that prevents the

Underbody construction with the carriers 104, 105, 106, 107 can collapse in the longitudinal direction of the car body.

Fig. 7 shows a three-dimensional representation of one of the upper ends of an underbody carrier, for example the carrier 1 according to Fig. 1. Like reference numerals as in Fig. 1 denote like parts. The surface formed by a plate-shaped area at the upper end of the carrier has in particular the total of eight holes 6 shown in FIG. 1, which are not visible in FIG. 7, because in each case a screw 85 extends through the bores 6, which in FIG its lower end is secured by a nut 87 against loosening and falling out. In this case, the screws 85 each hold in pairs a groove body 71, which has a longitudinal direction (from right rear to left front running in Fig. 7) consistent cross-sectional profile and in the embodiment has a U-shaped profile.

As shown in Fig. 8, these groove bodies 71 can be arranged in C-shaped grooves 83, 84, wherein the opening of the grooves 83, 84 down a passage of the shafts of the screws 85 allows. It is located between the plate-shaped upper end of the longitudinal strut 2a and the nut 87 each have a spacer 81a, 81b, which facilitates the assembly and leads to a uniform pressing the parts to be screwed together when the nuts 87 are tightened. A rotation of the heads of the screws 85 is prevented by the groove body 71.

The C-profile-shaped, mutually parallel grooves 83, 84 are preferably arranged on the underside of one of the longitudinal members 24 (in the example of FIG. 8 side members 24a). The corresponding area in the specific embodiment of FIG. 2 is located below the longitudinal member 24 a and is indicated by an arrow with the Reference numeral 83 marks to indicate that, among other things, the groove 83 is located in the area. The grooves 83, 84 and corresponding grooves on the other side of the car body on the other side member need not extend over the entire length of the side member. Rather, the grooves extend, for example, over a longitudinal section over which the longitudinal position of the underbody support is to be freely adjusted.

The underfloor devices shown in FIG. 9 are arranged in the underfloor space, which is limited, for example, by the underfloor construction explained with reference to FIGS. 3 and 4. The same reference numerals in Fig. 9 as in Figs. 3 and 4 denote the same parts. For example, the underfloor devices are various liquid containers 201, 202, an electric distribution device 204, a ventilation device 205, gas container 206, a transformer 207 and power converter 208, and a cooling device 209. Preferably, all these devices are on a plate-shaped element and / or or a support of the underbody construction so that they exert their entire weight or at least almost all of the weight on the U-shaped underbody beams 101-108.

The partial view shown in Fig. 10 of an underbody support 1 and two

Plate-shaped elements 91a, 91b illustrates that can be dispensed with longitudinal struts connecting adjacent underbody support. In turn

like reference numerals denote the same parts as in other figures. The carrier 1 is therefore, for example, the carrier shown in FIGS. 1 and 2. However, in other embodiments of U-shaped underbody supports plate-shaped elements can be screwed from below or otherwise secured from below, as will be described with reference to FIGS. 10-12.

The plate-shaped elements 91 a, 91 b are provided at their ends which are arranged at a small distance from one another in the region of the support 1, each with a vertical cross-section Y-shaped profile which surrounds the end of the plate-shaped support 91 and a from the Has end-extending plate-shaped part having through holes for passing screws 93 (see Fig. 12). The underside of the carrier 1 is provided with corresponding holes with internal thread into which the screws 93 are screwed. In the reverse view of FIG. 12, which shows the underside of the arrangement, the heads of the screws 93 can be seen, including a spacer 98 and again below the projecting plate-shaped element of the profile 94, which covers the underside of the carrier 1. In this way, not only, as shown in Fig. 11, two plates 91 are attached to the underside of the carrier 1, but in the same way, for example, another four plates, two of which fastened symmetrically to the median plane of the carrier on the other longitudinal strut 2a and two more plates fill the gap between the marginal plates.
