Description

Car body for a rail vehicle with a coupling fastening device and manufacturing method therefor

The invention relates to a car body for a rail vehicle. The carbody is preferably manufactured in integral construction, i. There are at least a bottom plate, side walls, a roof element and end walls joined together, and is made in particular of welded together aluminum extruded structures, which are designed as usual as a double-walled hollow chamber profiles, in particular profiles with opposite sheet-shaped walls, which are interconnected by webs. The webs or partitions separate extending in the longitudinal direction of the profile

Air chambers from each other. But not all of the above parts of the

Carcass be made of extruded structures. Rather, only individual areas of the car body can be made of extruded profiles. In trains that have several cars, the cars are connected via couplings, in particular so-called central buffer couplings. The couplings transmit the tensile and shear forces in the longitudinal direction of the car body and thus in the direction of travel of the train. The carbody according to the invention has below the carbody bottom a coupling-fastening device (eg a coupling plate) for

Attaching a coupling, via which the car can be coupled with another car of a train. The invention further relates to a method for producing such a car body and a rail vehicle with such a car body.

The clutch plate has a side facing the end of the car body in the longitudinal direction of the car body or a space open to this side, at or in which the clutch can be fastened or fastened, for example via a flange on a surface of the clutch plate. Instead of a coupling plate, another device may be provided on which the coupling is fastened or fastened and are transmitted via the forces, in particular acting in the longitudinal direction of the car body, between the coupling and the device. For example, the

Device having an arrangement of struts and a fastener. The coupling is attached to the fastener and the struts extend in different directions within a plane transverse to the longitudinal axis of the

Car body runs. The struts support the fastener against a frame that forms the outer edge of the device. In general, the device may be referred to as a coupling-fastening device. The fastener or another embodiment of the fastening device may, for example, comprise a block of material with a cavity open on one side into which the end of the coupling is or will be introduced. In this case, the block of material may, for example, have two parts, each of which overhanging a part of the cavity. The parts can be fastened together so that the end of the coupling can not be removed from the cavity without loosening the attachment of the parts.

In the car body may be in particular a car body for a tram, a local train, a long-distance train or a

Act high speed train.

From EP 2130739 A1 a rail vehicle body is known, the two

End modules has. The coupling over which the car body with adjacent

Car bodies is connectable, has an inner end which is directly connected to a transverse element of a substructure or a cross sleeper to transmit longitudinal forces. The substructure has a pair of side rails extending longitudinally from the coupling away from the cross member. The longitudinal members end on a frame which is connected to the underside of the car body. The end module also has on its underside a frame which, on its front side facing the adjacent carriage, has a window through which the coupling extends up to the attachment area at the end of the frame. The frame has a series of side members and additional longitudinal members. In the attachment region of the coupling, the frame has a plate-shaped inner beam.

DE 10129420 A1 describes a head structure for the shell construction of rail vehicles. The head structure has a bottom plate, a top plate (ie, a clutch plate), a longitudinal support extending longitudinally of the car body, and a plurality of local stiffening elements such as cross members. About a main cross member, the bottom plate is connected to the bottom plate of a car body. In addition to the provided in the bottom plate longitudinal support further eg oblique supports are possible, which can support the actual head shield substantially over its entire height. For receiving forces (hereinafter also referred to as coupling forces), which are transmitted via the coupling to the car body or vice versa, in addition so-called clutch boxes have already been proposed, which are fastened under the floor of the car body. Similar to the frame according to EP 2130739 A1, the coupling extends through a front opening of the coupling box to the rear end of the coupling box and is fixed there to the back of the coupling box, for example via a flange. The coupling box has longitudinal side walls and a bottom. The side walls and the front and the rear wall of the coupling box can at its top with a

be connected plate-shaped reinforcement of the car body floor. In addition, the coupling forces introduced into the rear end of the clutch box via various support elements, in particular at least one transverse strut, a longitudinal strut and optionally also diagonal struts, are introduced into the floor of the car body. In the places where the forces in the bottom of the

Car body are introduced, depending on the strength of the soil additional reinforcements required.

As these examples show, the coupling attachment means (e.g., the clutch plate) to which the clutch can be attached or attached serves to receive the forces exerted by the clutch on the car body and vice versa from the car body to the clutch Exercise powers. The forces are transmitted essentially in the longitudinal direction of the car body and thus of the train, but also transverse forces occur which act transversely to the longitudinal direction. In order for these forces to be transferred between the coupling fastener and the car body, the coupling fastener (e.g.

Clutch plate) via said power transmission elements, namely

Longitudinal supports, cross members, stiffeners and diagonal struts, connected to the floor of the car body. These power transmission elements support the coupling-fastening device and distribute the forces that are introduced by the coupling fastening device in the bottom of the car body. From the ground, in particular the bottom plate of a car body in integral construction, the forces are transmitted to the side members in the region of the transition between the bottom and the side walls. In the case of a floor panel, this is typically connected to the side rails over the entire length of the car body. The side members but do not have to be designed as individual components. Rather, they can from the outset z. B. be part of the soil.

To stably support the coupling-fastening device, in particular the clutch plate and to enable the power transmission between the car body and coupling, several power transmission elements are known to be required, which must be carried out so stable that they do not collapse at the maximum load and do not deform in a significant way. Despite a possible lightweight construction, as is the case with extruded aluminum profiles with air chambers. Assign that

Power transmission a considerable weight and is required according to much material and space below the car body floor. This place is e.g. not available for a bogie of the wagon, electrical cables and / or hydraulic or pneumatic lines. Since the coupling-fastening device in the end region (viewed in the longitudinal direction of the car body) of the car is arranged, the bogie has a considerable distance to the end of the car or

Car body have.

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

specify corresponding manufacturing method, which make it possible to reduce the number and / or mass required for the power transmission between the coupling fastening device and the car body power transmission element while reducing the required space.

It is proposed to use the coupling fastening device (eg the

Clutch plate) on its underside directly to connect to opposite sides of the car body extending in the longitudinal direction of the car body longitudinal beams, the compound serves to force directly between the

To transfer longitudinal beams and the coupling-fastening device. The connection is therefore a part which is essential for the structural analysis of the car body and for the dynamic transmission of power and not merely a lining of the underbody.

In particular, a carbody is proposed for a rail vehicle, the carbody comprising:

- a floor, two side walls, each connected to the ground,

at least two longitudinal members, which are respectively arranged on opposite sides of the car body in the transition region of the bottom to the side wall and extend in the longitudinal direction of the car body,

- A coupling-fastening device for fastening a coupling, via which the car body is connectable to a car body of another car, wherein the fastening means is arranged below the bottom and wherein a bottom of the fastening device is connected via a connection directly to the side rails.

The course of the connection is such that between the bottom of the

Car body and the connection remains a gap, i. the

Connection has a U-profile when viewed in a cross-sectional plane that is transverse to the longitudinal direction of the car body. Preferably, the connection of the underside of the coupling-fastening device to the longitudinal members on the opposite sides of the car body is continuous, so that in a direction perpendicular to the longitudinal direction of the car body cross-section, a trough-shaped profile is formed, wherein the interior of the trough below the bottom of the

Car body is located. In other words, throughout, the connection will pass from one side rail across the underside of the coupling fastener to the other side rail on the opposite side of the car body, i. is not interrupted.

If the coupling-fastening device is a coupling plate, this may be multi-part, in particular two parts, so that the handling of the plate is facilitated in the attachment with other parts.

The connection can in particular be produced by at least one plate-shaped part, wherein the opposite surfaces of the plate-shaped part extend in the direction of the connection and approximately in the longitudinal direction of the car body. In the case of the U-shaped profile design (see above), a trough is formed, which extends in the longitudinal direction of the car body and has a section in the longitudinal direction of the car body each having a U-profile of the type mentioned. In particular, the connection may extend over a longitudinal portion of the car body, in which the connection at least at one point, preferably at two points, via a from below up to the bottom of the car body extending support member is connected to the ground. These preferably two support members are preferably spaced apart in a horizontal direction transverse to the longitudinal direction of the carbody, the spacing portion defining the space through which the coupling extends from the carbody end to the coupling attachment means. The two spaced apart support elements therefore form together with the coupling attachment means and the body floor

Clutch box of the type mentioned above. In this case, the connection of the underside of the coupling-fastening device to the longitudinal members of the bottom of the

Form coupling box.

At the top of the coupling-fastening device or in particular at the top of the coupling box, in addition to the bottom of a

Reinforcing plate are located, in particular a reinforcing plate over which the

Clutch fastening device and / or (if present), the support elements are indirectly connected to the bottom of the car body. A distinction between the bottom of the car body and such a reinforcing plate is particularly important when the floor through a bottom plate

Extruded profiles is formed. The reinforcing plate initiates the forces to be exerted by the coupling fastener on the ground in a large area in the ground, that is, it distributes the forces. Especially when the bottom is formed by at least one extruded profile, the between two sheet-like, the

Having outer surfaces forming cover elements webs, the cover elements may be so thin that a force application in a small area would not be stable enough. In particular, in this case, the reinforcing plate also facilitates the production of a stable welded joint at the top of the coupling-fastening device. Due to a larger material thickness of the reinforcing plate compared to the

Covering element will make the welded joint more stable and easier to manufacture, since the reinforcing plate may be adapted to the coupling fastening device with regard to its thermal properties.

It is preferred that the connection between the underside of the coupling fastening device and the longitudinal members extends in the region of the longitudinal members over a longitudinal portion extending in the longitudinal direction of the car body. In this case, the longitudinal section is preferably longer than the longitudinal extent of the connection in the Area of the coupling fastening device. The connection is over the

Longitudinal portion preferably continuously connected to the side member. This embodiment has the advantage that it additionally stabilizes the car body. In the vicinity of the longitudinal section it is therefore also facilitated, e.g. Door openings or other openings in the side walls of the car body to provide. Elaborate further reinforcing measures, such as compensate for the weakening of the mechanical strength of the car body in the region of the openings, can be omitted or at least reduced.

Optionally, the coupling-fastening device is supported on its side, which is opposite to the side of the car body end, via at least one plate-shaped element on the bottom of the bottom of the car body. The plate-shaped element preferably has a lower edge which does not extend over its entire course parallel to the upper edge of the plate-shaped element. Rather, the lower edge can e.g. be generated in that, compared to a cuboid plate-shaped element, a part of the cuboid is omitted or cut off. The course of the lower edge may preferably be concavely curved so that space is created in the concavely curved region, e.g. can be used for parts of a bogie.

Preferably, two plate-like elements of the same shape are present, these plate-shaped elements in a horizontal direction, which extends transversely to the longitudinal direction of the car body, at a distance from each other. If a horizontal cross section below the carbody bottom is considered, the two form

spaced-apart plate-shaped elements, the z. B designed as a clutch plate coupling fastening device and the optionally existing two support elements which support the above-mentioned compound at the bottom of the car body, an H-profile, the two longitudinal legs of the H need not be parallel over its entire course. For example, For example, the portions of the longitudinal legs of the H formed by the two support elements may diverge from view of the coupling plate.

Regardless of the specific design and arrangement of

Power transmission elements that transmit coupling forces between the coupling fastener and the floor of the car body have the above-described connection between the underside of the coupling Fastener and the side rails on opposite sides of the car body the advantage that it allows the immediate transfer of forces between the side rails and the lower end of the coupling-fastening device. When in this description of the underside of the coupling fastener is mentioned, this does not exclude that the lower end of the coupling-fastening device is slightly below the connection to the opposite side members. However, it is preferred that the connection attaches to the lower end of the coupling-fastening device.

Due to the direct transmission between the opposite longitudinal members and the underside of the coupling-fastening device creates a stable construction, which makes it possible, from known embodiments of car bodies known power transmission elements, in particular diagonal struts and cross struts,

omit. This creates space for the installation of cables and hydraulic or pneumatic lines.

Further, since a direct transmission of force from the bottom of the coupling fastener into the opposite side members and vice versa can take place, the optional additional power transmission members for supporting the coupling fastener can be made smaller and lighter. In addition, less space is required for the power transmission elements, especially in the central region below the bottom of the car body. This also makes it possible to arrange the coupling-fastening device closer to the end of the car body (as viewed in the longitudinal direction). Therefore, a bogie can be placed closer to the end of the car body.

In addition, the cost of mounting the coupling-fastening device is reduced, since fewer parts are needed and because the connection to the longitudinal members in a simple manner at a distance from the car body floor and laterally to the side rails instead of just below the car body bottom in the middle Range can be produced.

Preferably, the connection is made from the underside of the coupling fastening device to the opposite longitudinal members of a plurality of plate-shaped individual parts, wherein the individual parts are preferably each Extruded profiles are and wherein longitudinal directions of air chambers and thus partitions between the air chambers in the extruded profiles extend in the longitudinal direction of the car body. However, it is also conceivable that extends at least in a part of the plate-shaped items, the longitudinal direction of the air chambers and thus the walls between the air chambers transversely to the longitudinal direction of the car body.

These items are preferably welded together. It is further preferred that the items are made of aluminum.

Although at least two of the individual parts may be designed plate-shaped, i. have approximately mutually parallel opposite outer surfaces, but the outer surfaces do not extend in a plane, but are curved. These items or in the case of a continuous connection, which is not made of individual parts, curved portions of the compound are preferably laterally, approximately below the opposite side members of the car body or slightly offset from the longitudinal axis of the car body. The curved individual parts or curved regions form a transition between a region of the connection which runs essentially in the horizontal direction and a region of the connection which extends from the bottom upwards to the respective side member. Alternatively, the curved item or the curved portion may lead directly to the side member. The curved item or curved portion may also be used as part of the body panel trim. Additional parts for the cladding can therefore be omitted or at least partially saved.

The connection from the underside of the coupling plate to the opposite side members can - viewed in the longitudinal direction of the car body - begin at the end of the car body. It can - as already mentioned - the compound form part of the outer contour of the car body, namely one below the

Car body floor located part of the outer contour, when the front end of the car body is considered. In this case, the gap between the connection and the bottom of the car body may be at least partially closed. However, at least one opening must remain in order to operate the coupling which is connected to the coupling fastening device. Optionally, this end cover of the intermediate space has at least one further opening in order to allow air to flow in due to the wind. This flowing air can be used, for example, to cool parts and equipment below the car body floor while driving. For example, in this way, a traction motor can be cooled, which is mounted on the rear of the coupling-fastening device bogie and drives the wheels of the bogie. Such other openings can also be used for passing cables and hydraulic or pneumatic lines.

As mentioned, the connection between the underside of the coupling fastening device and the opposite longitudinal members allows a direct

Power transmission between the longitudinal members and the lower end of the coupling fastening device. In addition, as also mentioned above and taken per se from the prior art, the coupling-fastening device (for example, clutch plate) is directly or indirectly connected to the bottom of the car body, so that forces between the ground and the coupling fastening device transferable are. In particular, the entire assembly of coupling attachment means and all of the power transmission members is configured such that a longitudinal force exerted by the coupling on the center of the coupling attachment means in the longitudinal direction of the car body is more than 10% and preferably more than 50% (e.g. %) is transmitted directly via the connection from the bottom to the opposite side members. Therefore, less than 90%, and preferably less than 50% (eg, 40%) of the longitudinal force is transferred directly from the coupling fastener via the further power transmission elements or directly from the coupling fastener to the carbody floor. This makes it possible to carry out these other power transmission elements particularly easily and / or in small numbers and / or with a small space requirement.

Another aspect of the invention relates to attaching the coupling-fastening device designed as a coupling plate to the connection and / or to the floor of the carbody (e.g., directly to the floorboard of the carbody or indirectly via at least one other element). This aspect can be in the case of

Attachment of the clutch plate with the bottom of the car body also be taken in isolation, ie there must be no connection from the underside of the coupling plate to the opposite side members of the car body. All other features such as the support elements described above, the at least one plate-shaped element, the embodiment of the particular as a clutch plate designed clutch fastening device with angled portions and / or the other embodiment of the above-described and yet to be described coupling box can also be realized or be realized if no connection from the underside of the coupling plate to the opposite side members of the car body is present. In this case, however, it is preferred that the height of the coupling fastening device, in particular of the

Clutch box (the height is considered in the vertical direction) is lower than in the case when a connection from the bottom of the coupling-fastening device to the opposite side members is present.

The coupling plate is to be stably fixed at its respective end (the upper end to be connected to the floor of the carbody and / or the lower end to be optionally connected to the connection). According to this further aspect of the invention, it is proposed that the coupling plate at the end to be fixed, a continuous (especially not, as would be the case in an extruded profile, interrupted by numerous cavities) surface and that this surface has a recessed area has, which is arranged between opposite edge regions of the surface. In particular, the coupling plate can therefore be made solid, i. have no air chambers as in an extruded profile. When the end having this surface is brought into abutment with a flat surface (eg, the floorboard of the carbody or a surface of the connection to the opposite side members), the edge portions of the surface at the end of the coupling plate abut substantially the entire surface of the planar surface while the recessed area forms a cavity together with the flat surface. This arrangement makes it possible to connect the edge regions of the surface with the flat surface, in particular to weld. These

Design with the recessed area of the surface serves to adapt the thermal properties of the coupling plate to the thermal properties of the material forming the planar surface. If the parts to be joined together are heated to produce a welded connection or other joining connection that requires heating of the parts, premature melting and consequent flow of the material may occur during heating of the part forming the planar surface the material of the clutch plate is not yet sufficiently heated. Due to the narrower edge areas of the surface and the

but the recessed area between them can be the material at the edge areas the surface of the coupling plate are brought about the same time at the same temperature required for the joining process. In addition, the cavity bounded by the recessed area and the flat surface can accommodate filler used in making the joint, eg, solder material or filler used in welding.

According to another idea, the coupling plate has at its lateral ends, i. considered in a horizontal cross-sectional area at the ends, the

opposite longitudinal members of the car body are close, in each case at least one angled region, so that in turn, viewed in a horizontal cross-sectional plane, the coupling plate forms a U-shaped or (with bilateral bend at the lateral ends) H-shaped profile. The angled portion serves to connect the coupling plate to this area with an additional power transmission element, via the forces between the bottom of the car body and the

Clutch plate to be transferred. Examples of such power transmission elements have been described above. The angled portions of the coupling plate make it possible to produce a joint connection, which requires heating of the parts to be joined, between the coupling plate and the further force transmission element, wherein the angled portion of the coupling plate is adapted to the thermal properties of the further force transmission element. Examples and embodiments will be discussed in more detail.

The coupling plate can be designed in particular at its lateral ends, but also in a multi-part design on the mutually connected edges of the parts of the coupling plate so that the ends have two web-shaped projecting portions at which the ends are welded to another part. In this case, at least one of the projecting portions on an angled edge, which forms a V-shaped or Y-shaped recess, which extends in the longitudinal direction of the projecting portion, together with a similarly angled edge of the part to be welded. The recess is open to the outside, i. If the two projecting portions have the angled edge, the openings of the recesses facing away from each other.

Preferably, a tongue-shaped end portion is also formed on the projecting portion with the angled edge, which in the direction of the the component to be welded protrudes furthest. This tongue-shaped end portion may be disposed in a recess of an end portion of the part to be welded before the weld is produced. In this case, the tongue-shaped

End region further preferably on the outside, pointing to the angled edge region, a recess which serves as a so-called Schweißbadsicherung. A weld pool fuse is e.g. in WO 2009/115198 A1. The recess prevents the weld from passing through the tongue-shaped area

is formed and takes in the welding process liquefied material.

The scope of the invention includes a corresponding manufacturing method for

Creating a car body. In particular, the method comprises the following steps:

Providing a body floor,

Providing two side walls,

Arranging and / or forming in each case at least one longitudinal carrier in the

Transition region of the bottom to one of the side walls, wherein the longitudinal members extend in a longitudinal direction of the car body,

- Providing a coupling-fastening device for fixing a

Clutch, by means of which the wagon body can be connected to a wagon body of another wagon, the fastening device being arranged below the ground,

Fixing a lower side of the fastening device via a connection directly to the longitudinal members,

- Connecting the side walls respectively with the ground.

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, the coupling fastening device and the connection must be present so that they can be connected together. However, it is possible, for example, to connect the floor to the side rails and optionally to the coupling fastening device or to finish the floor only when the side rails and the coupling fastening device are already connected to one another via the connection. Also, it is not mandatory that the side walls are then connected to the floor via the side rails, although this is preferred. This step can Alternatively, be carried out before the connection of the longitudinal members with the coupling-fastening device. A transition area between the ground and the

Sidewalls can still be discussed in any case, since the overall construction is predetermined. Also, the parts do not all have to be at the beginning

but can be provided, for example, when needed.

Embodiments of the method follow from the description of embodiments of the car body.

In particular, the connection can be made of aluminum extrusion box profiles which are welded together. As part of a pre-assembly, the connection can be made first and then the connection with the coupling-fastening device and the opposite sides of the

Car body connected in the region of the side members, in particular welded.

Embodiments of the invention will now be described with reference to the accompanying drawings. The individual figure names show:

Fig. 7 is an enlarged view of a portion of the illustration in Figure 6, wherein the portion is the connection area between the coupling plate and two additional power transmission elements welded thereto, and

Fig. 8 shows a cross section through part of the arrangement shown in Fig. 7.

Fig. 1 shows a car body 1 for a rail vehicle, in particular for a large-capacity passenger car. The view is directed to the end wall 5 of the car body 1, which has a central door opening T. On the end wall 5 are the front ends of the side walls 4a, 4b, which face each other from the viewpoint of the door opening T, the front end of the roof element 2 and the front end of the bottom 3. The car body 1 is shown in a state during its manufacture, although the production is not finished yet.

The car body 1 is manufactured in Integralbauweise. The bottom 3 is designed as a bottom plate. The side walls 4a, 4b and the roof element 2 are each prefabricated in one piece and have been connected to each other for the production of the car body 1, in particular welded together. The prefabricated modules 2, 3, 4 and optionally also other further components of the

Carriage 1 preferably aluminum extruded profiles, in which air chambers are arranged between aluminum sheets, which form the outer surface of the respective module, which are partitioned by partitions of aluminum sheet against each other. The partitions run in the manner of a truss when a

Cross-sectional profile is considered. In the longitudinal direction of the extruded modules, the partitions run continuously or at least over a longitudinal section. In this case, the mentioned modules 2, 3, 4 and also the other modules of the car body 1 produced by the extrusion process can be composed of sub-modules which were produced separately in the extrusion process and, for example, welded together were. The internal structure of the extruded profiles can be seen, for example, below in FIG. 1 and in FIG. 5. There, the partitions are designated by the reference numeral 31 and the air chambers by the reference numeral 30. It can also be seen that the bottom 3 is composed of at least five sub-modules 35a, 35b, 36a, 36b, 37 running side by side in the longitudinal direction (perpendicular to the plane of the figure in FIG. 5). These sub-modules 35, 36, 37 are welded together at their transitions 32. At the opposite lateral edges of the bottom plate 3, this is welded to the (with respect to the bottom plate 3) opposite longitudinal members 34 a, 34 b. The side rails 34 differ from most other sub-modules in that they have a greater distance between the outside

Sheets that form the opposite surfaces, have an angular cross-sectional profile and preferably the sheet thicknesses of the outer panels and the partitions are larger than the other sub-modules. The further sub-modules of the side walls 4a, 4b are not shown in Fig. 5.

However, the side members may be configured in any other suitable manner, e.g. B as I-profile. This does not only apply to this embodiment. Also, the

Side members may not be individual components, but may be integral portions of the floor or at the bottom of the side walls. Allen side members is common, however, that over the side members greater forces in the longitudinal direction of the car body

are transferable than over the other areas of the floor and the side walls.

All extruded profiles are preferably closed at their front ends by additional metal strips which are welded to the front ends. In the figures, some extrusion modules without these final metal strips are shown to reveal the internal structure of the profiles.

As shown in FIGS. 1 and 2, the side wall 4b has a door opening 12 in the illustrated end region of the car body 1. The strength of the side wall 4b is therefore weakened. In Fig. 2 also a part of a window opening 15 and in the upper region of the side wall 4b next to the door opening 12, a further window cutout 14 is also recognizable on the right.

In Fig. 1, the transition region between the bottom 3 and the side walls 4a, 4b is denoted by the reference numeral 10a and on the opposite side 10b. In These transition areas are the side members, which may for example be as shown in Fig. 5 and already described. However, other constructions are possible. For example, the longitudinal member may be part of the bottom plate, as indicated by the continuous, reaching to the outside of the car body horizontal lines in Fig. 1, or the longitudinal beam can be connected in a preparatory manufacturing with the bottom plate.

Before describing the construction of the coupling fastener according to the embodiment shown in FIGS. 1 to 7, it should be emphasized that the car body is relative to the side walls, the floor, the roof element and also to the manner of manufacturing the sub-modules or modules of the car body 1 can be executed differently. For example, it must be in the car body is not a car body in Integralbauweise. Also, the material may be different than aluminum. Further, other openings and openings may be elsewhere

be provided as e.g. shown in Fig. 1 and Fig. 2.

In the embodiment, the coupling-fastening device is a

Clutch plate, in the specific embodiment, a coupling plate 7, which is made of two parts 17a, 17b. The coupling plate 7 is preferably not an extruded profile with extruded cavities. Rather, the

opposite surfaces, which are longitudinally of the car body 1, each formed from a solid piece of material, with the exception of the best seen in Fig. 5 holes 41 for passing through fastening screws or fastening bolts for fastening the coupling, not shown, and with the exception of the further passage openings 40th , 44a, 44b. The two parts 17a, 17b are welded together at their common transition 42. The parts 17 may consist in particular of aluminum.

As best seen in Fig. 3 can be seen, the top of the clutch plate 7, which is due to the reverse view of FIG. 3 at the bottom of the clutch plate 7, connected via a reinforcing plate 20 to the bottom 3. For example, will be the first

Reinforcing plate 20 welded to the bottom 3 and then the coupling plate 7 welded at its top to the reinforcing plate 20. Alternatively, the

Clutch plate 7 are first welded to the other shown in Fig. 3 and other figures additional power transmission elements 6a, 6b, 9a, 9b and then these are welded in horizontal cross-section H-shaped construction at its upper side with the reinforcing plate 20. The H-shaped cross-sectional profile of this construction is best seen in FIG. This figure shows that the two parts 17a, 17b respectively at their outside, to the lateral edge of the car body facing ends (top and bottom in Fig. 6), two angled portions 53, 54 (on part 17a) and 55, 56 (on the part 17b). These angled portions 53, 54, 55, 56 are connected to the other power transmission elements, namely the angled portion 53 with the support member 6 a, the angled portion 54 with a

plate-shaped element 9a, which is welded together from two parts 58a, 59a, the angled portion 55 with a second support member 6b and the angled portion 56 with a second plate-shaped member 9b, which is welded together from two parts 58b, 59b. In this case, the support elements 6a, 6b form part of the long legs of the H-profile, these parts of the long legs from the perspective of

Clutch plate 7 diverge, while the plate-shaped elements 9a, 9b parallel to each other in the longitudinal direction of the car body. Also, the support members 6a, 6b may be welded together from two parts, as can be seen by a horizontal line on the support member 6a in Fig. 3. The division of the plate-shaped elements 9a, 9b is also horizontal in the embodiment, as also best seen in FIG. 3 can be seen. The welded joint 61 of the two parts 58a, 59a is also shown in Fig. 3 by a horizontal line, as the welded joint 62 of the two parts 58b, 59b of the plate-shaped member 9b. In this case, the upper part 59a, 59b may have through-holes, e.g. To be able to pass cables or lines.

As shown in Fig. 3 and Fig. 6, the reinforcing plate 20 also has an H-shaped profile, but the transitions between the two longitudinal limbs and the transverse leg of the H-profile are rounded. The corresponding rounded edges are designated by reference numerals 22 and 52 in FIG. Further, the end portions 21a, 21b of the longitudinal legs taper with respect to their measured in the vertical direction (perpendicular to the plane of FIG. 6 and in the vertical direction in Fig. 3)

Material thickness.

A particularly preferred way of producing the welds of the angled regions 53, 54, 55, 56 to the adjacent further force transmission elements 6a, 9a, 6b, 9b will now be explained with reference to Fig. 7, wherein only the welded joints are shown to the power transmission elements 6a, 9a. The other two

Welded connections can be made in the same way. The angled regions 53, 54 of the part 17a of the coupling plate 7 have at their free ends in each case two tongue-shaped regions 74a, 74b. In the following, only the area which contains the connection between the angled region 53 and the support element 6a will be described in more detail. The other transition region from the angled region 54 to the plate-shaped element 9a or to its upper part 58a and its lower part 59a can be carried out in the same way. The tongue-shaped

End portions 74a, 74b are spaced from each other and there is a cavity 101 between them. In the course of the tongue-shaped portion 74a, 74b up to the free end of a recess 73 is provided on the outside, which as

Sweat protection is used.

The end of the support element 6a pointing in the direction of the angled region 53 likewise has two projecting mutually parallel end sections 105a, 105b, so that a cavity is also created between the end sections 105 which forms part of the assembled configuration shown in FIG Cavity 101 is. In the assembled state, the cavity 101 is circumferentially bounded, on one side of the angled portion 53 and on the other side of the support member 6a. At this time, the end portions of the angled portion 53 and the support member 6a overlap with the tongue-shaped end portions 74a, 74b abutting on the inner side of the projecting end portions 05a, 105b. At this time, the outside recess 73 of the tongue-shaped end portions 74a, 74b extends toward the free end of the tongue-shaped end portions 74a, 74b beyond the butting portion where the projecting end portions 105a, 105b of FIG

Support member 6 a to the material of the angled portion 53 abut. On the outside of this abutting region, both the material of the support element 6a and the material of the angled region 53 are chamfered, so that a V profile or a Y profile is produced by the resulting chamfered surfaces 72a, 72b. Within the two legs of the Y or V-profile is thus an externally accessible recess 71. As well as the shape features described above

Transition region, this recess 71 extends in the vertical direction (perpendicular to the plane of FIG. 7) over the entire end of the angled portion 53 and the support member 6a. This also applies to the cavity 101. In the assembled state described above, the weld is not yet established. In a manner known per se, however, a weld can now be created in each case in the region of the V-shaped or Y-shaped recess 71. The result is two welds in each transition region between the clutch plate and the additional power transmission element. An advantage of the projecting end portions with the intermediate cavity 101 is that the material thicknesses of the abutting, to be welded together parts in the joint area are about the same size, so that the heat capacities are about the same size. at

Heating the materials to make a weld, the temperatures of the materials of the abutting parts are therefore about the same size. Due to the existing material contact, a temperature compensation by heat conduction can also take place. In addition, the mated end portions of the parts to be welded together due to the internal tongue-shaped end portions are already in a provisionally fixed relative position, so that the production of the weld is facilitated.

Variants of the embodiment shown in Fig. 7 are possible. On the one hand, the angled area 53 need not be angled with the angle shown in FIG. 7 with respect to the part of the coupling plate shown in FIG. 7 below, but the angle can vary depending on the desired construction. The same applies to the other angled region 54, which may also be omitted in another embodiment of the coupling plate. Also, the angled portion 53 may be omitted while the angled portion 54 is present. Furthermore, the tongue-shaped

End portions both or only one of them on the other part (e.g.

Support element 6a), but not be provided at the angled region.

In particular, it is also possible that one of the two parts to be joined has a tongue-shaped end portion and the other part the other tongue-shaped portion.

Fig. 3 and Fig. 7 show that the bottom shown in Fig. 3 above the

Clutch plate 7, the support elements 6a, 6b and the plate-shaped elements 9a, 9b does not have a continuous planar surface, but is profiled. These

Profiling serves the thermal properties, in particular the effective heat capacity, of said elements to the thermal properties of

To adapt components with which the elements welded or otherwise by Heating should be connected. The top of the elements can be designed in the same way. At the top, the elements are welded to the reinforcing plate 20. The profiling causes the effective heat capacity to decrease. For this purpose, material is cut out in the middle region of the surface at the lower end. Only the edge regions of the surface, which are preferably designed flat, wherein the two opposite edge regions preferably end at the same height level, abut the part with which the element is to be welded or connected in another way under the action of heat. The middle area of the end surface of the part 17a of the clutch plate 7 is designated by reference numeral 89 in FIG. The transition of the central region 89 to the two opposite edge regions 69a, 69b is denoted by reference numerals 79a, 79b. These transition regions can, as indicated by parallel lines in Fig. 4, be executed rounded. Since the portion 17a in the embodiment shown in Fig. 7, the two

has angled portions 53, 54 and thus has a T-shaped cross-sectional profile, there is a third edge portion 69 c, wherein the transition region from the central, recessed surface portion 89 to the third edge portion 69 c with the

Reference numeral 79c is designated.

Accordingly, the slot member 6a has a central, recessed

Surface region 87, at the opposite edges of the edge regions 67a, 67b are present, which rest during the preparation of the connection to the adjacent part of this. The transition regions are designated by reference numerals 77a, 77b. The central, recessed area of the end surface of the part 58a (on the right in FIG. 7) is designated by reference numeral 88, the opposite edge regions by reference numerals 68a, 68b.

Fig. 8 shows a cross section through the part 17a outside the angled portions 53, 54, wherein the image plane is perpendicular to the image plane of Fig. 7 and in the longitudinal direction of the car body, i. in the horizontal direction of the image plane in FIG. 7.

A preferred embodiment of a connection from the underside of the coupling plate 7 to the opposite longitudinal members 34a, 34b will now be described below. In this case, the connection 8 is configured continuously from the one longitudinal carrier 34a to the other longitudinal carrier 34b and in this case has a trough-shaped cross-sectional profile (FIG. 5). The compound 8 is connected to the longitudinal members 34 each over a welded joint 32 is connected. It is composed of several sub-modules (in Fig. 5 from left to right) 19a, 18a, 25a, 26a, 27, 26b, 25b, 18b and 19b, these sub-modules are designed plate-shaped and each with two

adjacent parts are connected via a weld 32. Similar to Fig. 7 for the angled portions 53, 54, tongue-shaped end portions may be provided which allow mating of the parts to be joined prior to welding, which have a weld pool and which are designed so that the effective heat capacities of each other to

connecting parts are similar or the same.

In order to achieve the trough-shaped profile, two of the sub-modules, namely the modules 18a, 18b are curved. They form the transition from the bottom of the tub to the side walls of the tub.

In the longitudinal direction of the car body (perpendicular to the image plane of Fig. 5) extend the sub-modules 18a, 25a, 26a, 27, 26b, 25b and 18b over a longitudinal portion which is approximately equal to the longitudinal extent, the combination of the clutch plate 7 with the support elements attached thereto 6a, 6b and also attached to the coupling plate 7 plate-shaped elements 9a, 9b has. This refers to the longitudinal extent at the bottom of the construction. At the top of the construction is the

Longitudinal extent greater, as can be seen from Fig. 3, since the plate-shaped elements 9a, 9b have at its lower edge a curved course. The longitudinal extension of the tub bottom of the connection 8 can also be slightly larger than the

Longitudinal extension of said construction on its underside, as Fig. 4 indicates.

Optionally, the trough-shaped connection 8 in the trough sidewalls in each case on an opening 13, as best seen in Fig. 2 and Fig. 1 can be seen on their side walls. Alternatively or additionally, the longitudinal extent of the portion or portion 19a, 19b, which is connected to the respective side rail 34a, 34b, much larger than the longitudinal extent of the tub bottom, i. at the bottom of the connection 8. This greater longitudinal extent is made possible, for example, by the projecting area B of the partial module 19b shown at the bottom right in FIG. The bigger one

Longitudinal extent, over the entire greater longitudinal extent of the connection 8 abuts the side rail 34, improves the stability and makes it possible Therefore, to transfer larger forces in the longitudinal direction between the longitudinal member 34 and the connection 8.

As shown in FIG. 5, the support elements 6a, 6b are connected on their underside to the connection 8, namely here the sub-modules 26a, 26b. With these sub-modules 26a, 26b, the plate-shaped elements 9a, 9b are also connected on its underside. Also, the coupling plate 7 itself is connected to the connection 8, namely with the central part module 27 and with their angled edge regions with the sub-modules 26a, 26b. All of these connections of the coupling plate 7, the supporting elements 6a, 6b and the plate-shaped elements 9a, 9b are preferably welded joints, the underside of the construction shown in Fig. 3 above preferably being as described with a recessed, recessed surface area

is designed.

The arrangement open in FIG. 1 and FIG. 5 towards the end side below the

Car body floor 3 can be at least partially closed by plate-shaped elements (not shown). Also, the open ends of the modules as mentioned above, e.g. be closed by welded metal strips.

Regardless of that of the car body floor 3 together with the

Reinforcing plate 20, the clutch plate 7, the two support members 6a, 6b and the central region of the trough bottom of the compound 8 in the above sense be referred to as a clutch box. However, to the front side of this coupling box is at least partially open, so that the clutch through the interior of the

Clutch box can extend through to the coupling plate 7 and can be fixed there.
