Description

description

Modular system for fixing an underfloor component to different car bodies, method for mounting an underfloor component to a car

Car body, and rail vehicle fleet

Technical area

The invention relates to the field of rail vehicles, in particular in the field of modular Unterflomanordnungen the car body of the rail vehicle. The invention also relates to a method for mounting a modular

Underfloor component on the body of a rail vehicle.

Prior art

Rail vehicles have a variety of different components to be attached to the car body of the rail vehicle. For example, utility components, such as transformers or air conditioners, may be attached to the vehicle body. Some of the components are mounted below the Bode of the car body, in order to achieve the best possible space utilization.

In the case of known systems, the components to be fastened to the underfloor of the rail vehicle, but also side skirts of the rail vehicle and floor slabs, are adapted to the specific vehicle. As a result, for each vehicle type, the underfloor components must be redesigned or existing underfloor components must be adapted. The adaptation of the side skirts and floor slabs is usually done via an additional support structure.

Although there are solutions for mounting support in which a combined assembly of the underfloor components and the side skirts and the floor panels is offered, but they require more space in the vehicle longitudinal direction. This involves, in particular in the underground installation, some disadvantages, since the mounting space underfloor is limited. In addition, the problem of the complex adaptation of the

Underfloor components not solved to different vehicle types.

EP 1 340 662 A1 describes an underbody assembly for a

Rail vehicle. The underbody assembly has a structural element extending in Extending longitudinally between the longitudinal sides of the railway car, said structural element having a pair of longitudinally extending support members which are transversely spaced from each other. The underbody assembly forms a

Component niches between the longitudinally extending support members. The

Component niche is capable of receiving an underfloor component, wherein the structural member is adapted to partially support the underfloor component.

US 4 825 774 A describes an underfloor structure of a rail vehicle having a housing surrounding underfloor components of a rail vehicle. The underfloor components are mounted directly on the car body of the rail vehicle. The housing surrounding the underfloor components is mounted to the car body by means of rails.

US 8 083 280 B2 describes the assembly of several boxes on the underside of a vehicle. The boxes can be used for storing luggage. The boxes are available in different sizes and can be used together to meet vehicle-specific requirements and provide maximum luggage space.

Disadvantages of the prior art

The systems known in the art require an adaptation of the underfloor components, if they are to be used for different types of vehicles. This is not only expensive, but expensive, since the components may need to be changed in size and / or shape. In addition, the mounting systems of the underfloor components for attaching the

Underfloor component can be adapted to the vehicle body of the rail vehicle vehicle-specific in order to attach the adapted underfloor components and to be able to position reliably.

problem

It is therefore an object of the present invention to provide a fastening system for underfloor components, which allows to assemble the same or different underfloor components without adapting the underfloor component to different vehicle types. The system according to the invention should also have a Modular construction of the underfloor components and their fastening, so that both the development costs and the installation costs for different types of vehicles are reduced. In addition, the fastening system should take into account the limited mounting space at the bottom of the rail vehicle and can be used in a correspondingly space-saving manner.

Inventive solution

This object is achieved by a modular system for securing a

Underfloor component on different car bodies according to claim 1, a method for mounting an underfloor component according to claim 13, and by a

Rail vehicle fleet solved according to claim 15. Further embodiments,

Modifications and improvements will become apparent from the following description and from the appended claims.

According to one embodiment, a modular system for mounting an underfloor component to different car bodies of rail vehicles is provided. The modular system has at least one underfloor component with a container for receiving and securing a rail vehicle component in the container. Furthermore, the modular system has at least first fastening elements for fastening the underfloor component to a first vehicle body and at least second fastening elements for fastening the underfloor component to a second vehicle body, which is different from the first vehicle body. The

Fasteners are designed for load-bearing attachment of the underfloor component to the respective car body. In addition, the first and second

Fasteners each have an identical interface for attaching the respective fastener to the container of the underfloor component. The first

Fasteners also each have a first interface for attaching the first fastener to the first car body and the second

Fasteners each have a second interface for securing the second

Fixing element on the second car body. The modular system is designed so that the underfloor component can be attached to the different car bodies without further adaptation of the container and by selection of the respective fastening elements. Due to the modular system for attaching an underfloor component to different car bodies of rail vehicles can be a simple and

cost-effective adaptation of the underfloor component to be fastened can be realized. These interfaces between the car body and the container of

Underfloor component created, which are independent of the car body design or type (also, for example, regardless of the position of a longitudinal member of the car body). The interfaces can be standardized and identical for all underfloor components. Furthermore, the modular system described herein according to embodiments is flexible for changes and new body types. The modular system after

Embodiments may include a kit having, for example, identical containers for underfloor components, which can be mounted on different car bodies. Furthermore, various underfloor components can be provided standardized, for example via standardized containers of different sizes. In this case, then the adjustment of the attachment of the underfloor components, concretely the container to different types of carts by selecting a suitable fastener having a standardized interface to the container of the underfloor component, but in the rest of the design of the corresponding

Carriage type is adjusted. This makes it possible to produce the underfloor components independently of the specific type of car body standardized

Saved manufacturing costs. The adaptation to the load-bearing attachment of the underfloor component to the different car bodies is done by selecting the adapted to the respective car body fasteners. Thus, the same fastening system can be used for the different types of carts or projects.

In this case, a problem is addressed, which today almost all redesigned

Railway vehicles concerns: the underfloor construction of each newly designed

Rail vehicle differs from previously known rail vehicles. For example, there are significant differences in the underfloor structure of a fast train compared to a regional or local train. In known systems, therefore, different, for each vehicle type individually created solutions for

Underfloor components, side skirts and floor panels designed. There is virtually no reuse effect, which leads to high development and assembly costs. With the modular system according to embodiments, in which for the same

Underfloor component different fasteners are provided which have a standardized interface to the underfloor component, it is possible to be flexible enough to meet different requirements with a flexible system. These different requirements may be, for example, the varying carbody width in different types of vehicles.

It is thereby possible that an underfloor component with identical

Container on different car bodies by selecting the appropriate

Fastening elements can be mounted. The underfloor component may, in addition to the structural interfaces for the fasteners also have other Schnittstellten, for example, electrical interfaces, hydraulic interfaces, or pneumatic interfaces.

By example, standardized execution of a particular

Underfloor component especially for different types of car bodies, at least as regards the interface to the fastener, resulting in a higher

Reuse effect, since the underfloor components can be used for almost all vehicle types. The adaptation to different car bodies by selecting the appropriate fasteners also allows to provide sufficient flexibility with respect to the car body interfaces. The

Fasteners in embodiments typically have an identical or similar interface to the underfloor components, wherein the interface of the fasteners is not specified to the car body and depending on

Carriage type can be included in the choice of fasteners.

Another effect of the modular system according to embodiments is that suppliers can adjust to the standardized components and thereby the cost can be reduced. The same interfaces and the same or similar

Design of the underfloor components also reduce the assembly effort, and thereby the installation costs. For example, a uniform size for a particular underfloor component for different vehicles of a rail fleet can be specified. Specifically, the size specified on the container of

Underfloor component refer. By specifying the size by the

Rail vehicle manufacturers can control and optimize the arrangement and the space requirements of the individual underfloor components, which allows better space utilization. The fasteners are typically releasably connectable to the container of the underfloor component and the car body, creating a light

Interchangeability is guaranteed.

The fasteners are used in particular the lastaufnehmenden

Attachment of the respective underfloor component to the car body, d. h., the

Fasteners bear the weight of the underfloor component. Other load-bearing elements, for example, cross members attached to the body are not required and can be saved, whereby the available space is increased. The attachment of the underfloor components on the car body is thus preferably without such cross member.

The containers may further comprise support elements which form an inner support frame of the container and carry the container-side interfaces. The interfaces are then part of the scaffold. On the scaffold also side walls of the container can be attached.

Alternatively, it is possible that the interfaces directly from the

Side walls of the container are formed or attached to this. In

Depending on the weight of the underfloor component, the containers may have the additional inner scaffold or only the sidewalls.

Furthermore, it is possible that the scaffold alone forms the container, i. this one is open.

According to one embodiment, the containers of different underfloor components have a standardized width, i. in the transverse direction of the

Car bodies, but over different lengths, ie in the longitudinal direction of the car bodies. The standardized width can be configured identically for a vehicle fleet, ie a multiplicity of different vehicles. The standardized width preferably corresponds to a width which is also suitable for installation in the narrowest vehicle of the vehicle fleet, in particular the maximum possible width for installation in the narrowest vehicle for a given clearance profile. The bottom of the container may form the floor panel of the vehicle. Thus, the bottom plates of a vehicle fleet may have the same width. In one dimension, here in the transverse direction of the car bodies, the containers are preferably the same, but they may be different in the other dimension, ie in the longitudinal direction. This makes it possible to use the same fasteners for different containers. For the attachment of different containers, and thus underfloor components, on the same type of car body are thus the same

Fasteners needed. The first and second fasteners are the same. The modular system may comprise a standardized box which at the same time forms the housing for the underfloor component. The essential elements for adapting the box to a particular vehicle, in addition to the fasteners and the

Side skirts.

In one embodiment, the first and second fastening elements are different, in particular the first and second fastening elements are different in size and / or shape and / or in their structural configuration. The flexible design of the size and / or shape of the fasteners adaptation to different geometries of the car bodies is possible. For example, by adjusting the size and shape of the fasteners, the position of the interface between fastener and car body can be varied.

According to one embodiment, the first and second fastening elements differ in that the interfaces of the fastening elements to the first and second car body are at different positions with respect to the interface to the underfloor component. This makes it possible to provide a standardized or the same interface between the fastener and underfloor component at the same time and to allow mounting on different car bodies.

In one embodiment, by selecting the respective

Fasteners an adaptation to the carbody size and / or the

Car body shape and / or the height of the car body floor. In this case, the adaptation to the car body size or shape can be done exclusively by selecting the appropriately shaped and work in a time- and cost-saving.

According to one embodiment, the nature of the first and second interface of the first and second fastening elements to the car body is the same, wherein

in particular the interfaces of the first and second fastening elements for

Car Body a compound of the first and second fasteners to a C Allow rail of a car body. As a result, a further simplification of the fastening system can be realized and the assembly costs are reduced. An attachment to the car body by means of C-rail provides an easy-to-install and flexible positioning of the underfloor component on the car body.

In one embodiment, the first and / or second

Fasteners at least one more interface for the attachment of a side panel for the rail vehicle. The fasteners may be designed to carry the weight of the side panel. As a result, no separate structure for the side panel is required, which reduces both the manufacturing costs and the installation costs by reducing assembly costs. By the

Fastener that provides the attachment function for multiple components of the

Rail vehicle, the reuse effect of the system also improves. In one embodiment, a bottom plate for the

Railway vehicle can be provided, wherein the bottom plate, for example, on the underfloor component releasably fastened bar. Corresponding interfaces may be provided on the underfloor component. Overall, the system described thus provides a design that can do without additional support for side skirts and / or floor panels, which also has a positive effect on the weight reduction of the rail vehicle.

According to one embodiment, the container of the underfloor component has a further interface for the attachment of a side panel for the

Rail vehicle, the side panel closes the container laterally. The side panel can thus take over both the function of the outer end of the container as well as the function of the side panel of the rail vehicle. The container is so open without this side panel at least on this side.

In a further advantageous embodiment of the modular system in which the containers used for a vehicle fleet have a standardized width, each adapted side panels can be provided for different vehicles. The receiving space under the car body for receiving the underfloor component may be formed by the container and the side panel adjacent to the container. The side panel can be more curved or bulky on wider vehicles

be extended box-shaped. In an area adjacent to the container, the Side panel have a substantially horizontal course, in a region adjacent to the side wall of the car body area a substantially vertical course. Between the adjacent to the container and the adjacent to the side wall of the vehicle area, the side panel runs in the narrowest vehicle of a vehicle fleet preferably substantially straight, while the side panel runs at wider vehicles substantially bulbous curved. With wider vehicles, the receiving space is thus increased compared to narrower vehicles.

The side panel is visible from the outside and takes over, for example, the function of aerodynamic air ducting and paneling.

Additionally or alternatively may be attached to the bottom of the support frame of the container and / or on the fastening elements for closing the container on its underside.

The side cover, regardless of whether it is attached to one or two fasteners and / or the container, articulated, for example by means of a hinge, be attached so that when opening the side panel at the same time access to the container or located in the container Components is possible.

By attaching the side panel directly to the

Fasteners for the container or on the containers themselves additional fasteners for the side panels are avoided, whereby the available space is better utilized.

The container may form part of the underfloor structure of the rail vehicle, i. the side trim, for example in the form of side skirts, may be attached to the container, e.g. about hinges.

The container can open laterally and alone through the side skirts

be closed, or have special side walls for special requirements on the seal or for the supply of filtered air.

The container may form a mounting structure for a bottom plate.

Preferably, the underbody of the container may form the bottom plate. In this case, the height of the subfloor can be adjusted via the individualized fasteners. The fasteners may form bulkheads to control or prevent airflows to the box (if the underfloor component requires filtered air) or to provide fire protection.

Possible components for housing in a container

For example, a toilet tank, which here no lateral air supply to the container are required, converter, brake equipment, such as compressed air tanks or a pneumatic control, compressor, air conditioning, batteries, e-distributors, fuses, tanks or a transformer.

According to a preferred embodiment, the fastening elements are configured such that in each case a predefined distance remains between underfloor components and car bodies, or between the container and the car body, in the assembled state. Thus, the underfloor components or containers together with the car body limit a cavity for receiving at least one cable channel, fluid lines or supply and / or disposal lines. Between underfloor component or container and car body arranged cables or lines can serve the connection of the underfloor component. For the connection of the

Underfloor component is this preferably laterally or at its top, i. in the mounted position on the side facing the car body, in particular laterally to

Offset center plane of the car body, or provided in the direction of the longitudinal side of the car body with at least one connecting device. Thus, a mounting-friendly accessibility of the connection device is ensured.

According to one embodiment, an adjustment of the lateral position of the underfloor component with respect to the car body width is made possible by the selection of the different fastening elements for the underfloor components. By selecting the fastener from a group of fasteners with

different size, the position of the underfloor component can be adjusted, in particular with respect to the longitudinal axis of the rail vehicle.

In one embodiment, one of the first and second

Fasteners each provided for a particular type of car body. The specific adaptation of the fasteners to a trolley type allows a modular, yet safe and reliable attachment of the underfloor component to the car body. According to one embodiment, the container of the underfloor component has four interfaces for each of four first or four second fastening elements. As a result, a secure mounting of the underfloor component on the car body can be ensured. The skilled person will understand that the number of interfaces of

Underfloor component to the fastener and used

Fasteners may depend on the underfloor component geometry.

In one embodiment, the system has a plurality of same

Underfloor components, each with a container of identical design, wherein the container of the underfloor components each have the same interfaces for securing a first or second fastener. Due to the standardized design of the

Underfloor component can further simplify the modular system

be made. For example, the housing of the underfloor components may have substantially the same dimensions.

In one embodiment, the system has at least two

Underfloor components with different, i. not identical containers, wherein the container of the underfloor components each have the same interfaces for securing the first or second fasteners.

According to further embodiments, a system for modular

Underfloor mounting of underfloor components provided on different car bodies of rail vehicles. The system has an underfloor unit consisting of an underfloor component and at least one fastening element. The underfloor unit is adaptable to different sizes of vehicle types by selecting a fastener from a group of different fasteners.

In addition, the fasteners from the group of different fasteners have a standardized interface between the underfloor component and fastener and an interface between the car body and

Fastener on. The fasteners from the group of different fasteners can attach the underfloor component load-bearing on the car body. Adaptation of the underfloor unit to different sizes of

Vehicle types are exclusively based on the design of the fastener. According to embodiments, a rail vehicle with underfloor component is provided. The rail vehicle has releasably connectable

Fastening elements with a standardized component-side interface to the container of the underfloor component and a carriage box-side interface to the

Car body of the rail vehicle for releasably attaching to the car body, wherein the fastener fastened the underfloor component load-bearing on the car body. The carriage box-side interfaces of fasteners for different underfloor components are the same. Likewise, the component-side interfaces to different underfloor components may be the same. Thus everyone can

Fasteners have the same carriage box-side interface and the same component-side interface, but the fasteners are otherwise adapted to the respective car body.

Thus, according to one embodiment, a fastening system is provided which has at least two, typically several groups of fastening elements which are each adapted for load-bearing attachment of an underfloor component to a wagon body. The fasteners of a group are identical. The fasteners of different groups are different. All

Fasteners of all groups can use the same cart side

Have interfaces and the same component-side interface, so a standardized fastening system for different or the same

To provide underfloor components on different or the same car bodies.

The fastener allows adaptation to different car bodies of rail vehicles by selecting the fastener from a group of fasteners with to different car bodies

customized sizes and / or shapes.

According to embodiments, the fastening elements may, in addition to the carriage box-side interfaces and the component-side interface, also have at least one further interface which is suitable for fastening

Cladding elements for dressing the underfloor component is used. This interface can also be referred to as a panel-side interface. According to one embodiment, the fastening elements each have a support region on which the underfloor component rests in the fastened state. The support area can, for example, partially surround the underfloor component.

According to one embodiment, the containers may be closed or partially or completely open frame constructions, i. they are formed by the above-described scaffold. The containers may for example be closed on all sides, or at least closed at the bottom and three or all sides. Frame structures (scaffolds), however, are open construction units.

According to another embodiment, a method for mounting an underfloor component to a car body of a rail vehicle is provided. The method comprises: providing an underfloor component with a container for receiving and securing a rail vehicle component in the container, wherein the container has identical interfaces for first and second fasteners to fasten the underfloor component load-bearing on the car body. The method further comprises: selecting first or second fastener elements, wherein the second fastener elements are different from the first fastener elements, and wherein the first and second fastener elements each have a structurally identical interface for attaching the respective fastener element to the container

Underfloor component have. The first fastening elements each have a first interface for fastening the first fastening element to the first vehicle body, and the second fastening elements each have a second interface for fastening the second fastening element to the second vehicle body. By selecting the fastener, it is possible to attach the underfloor component to different car bodies of rail vehicles.

According to one embodiment, the method comprises attaching the selected fastener to the underfloor component and to the carbody.

The invention can be used wherever different

Car bodies are used for vehicles, in particular rail vehicles.

In particular, the invention can be used where same or similar

Underfloor components to be attached to different car bodies. According to one embodiment, a rail vehicle fleet has at least a first rail vehicle with a first car body and at least a second rail vehicle with a second car body, which is different from the first car body. At the first car body and the second car body is in each case an underfloor component, each with a container of identical construction for receiving and

Attachment of a rail vehicle component mounted in the container. The respective container is mounted load-bearing with first fasteners on the first car body and second fasteners on the second car body. The first and second fastening elements each have a structurally identical interface for fastening the respective fastening element to the container of the underfloor component. The first fasteners each have a first interface with which they are attached to the first car body, and the second fasteners each have a second interface with which they are attached to the second car body.

On rail vehicles with different car bodies thus identical containers are fixed by using the respective fasteners, without the need for an adaptation of the respective container of the underfloor components.

embodiments

The following is a modular system for attachment of

Underfloor components on car bodies of a rail vehicle described. The

The invention is not limited to the examples shown in the figures, but may be used for various underfloor components or fasteners and in various embodiments.

1 shows a modular system 100 with an underfloor component 1 with a container shown here closed and first fastening elements 2. In the embodiment shown in Figure 1, the modular system 100 has four first

Fasteners, which are each attached to a corner of the underfloor component. The fastening elements 2 have, as will be explained in detail later,

(in particular standardized) interfaces, i. component-side interfaces for attaching the fastening elements 2 to the underfloor component 1. Also the

Underfloor component 1 includes standardized interfaces to the

Attach fasteners to the underfloor component. The exemplified first fasteners may be four equal parts. In another embodiment, the four first fasteners may be different from each other

differ. In addition, the skilled person will understand that the fasteners are not limited to the number shown. In one embodiment, the number of fasteners may be selected according to the type of underfloor component.

The underfloor component as described herein may be used as a

Component to be understood, which is to be attached underfloor rail vehicle. For example, the underfloor component as described herein may be

Functional elements, such as supply components (e.g.

Transformers, ventilation systems, batteries, tanks and the like). In one example, the underfloor component may include a box or container housing one or more functional elements. In another example, the underfloor component may consist of a functional element and its housing.

In particular, the housing of the underfloor component, or the box or container the underfloor component, a standardized interface for attaching the

Fastener on. The type of material of the underfloor component, the box, or the housing can be chosen flexibly and according to the requirements.

Figure 2 shows a view of an underfloor component, which is attached to two different car bodies 10, 20 of rail vehicles. The car bodies 10 and 20 differ in the example shown in Figure 2 by the height in the vertical direction, which affects the mounting of the underfloor component 1. In addition, the car bodies 10, 20 differ in width in the horizontal direction, which is also important for the assembly of the underfloor components.

The underfloor component 1 of Figure 2 is attached by means of first fasteners 2a to the first car body 10, or by means of second fasteners 2b to the second car body 20. Generally, the fasteners can after

Embodiments hold the weight of the underfloor components on the car body load-bearing, in particular without a further support structure attached to the car body is needed. As mentioned above, the different fasteners 2a and 2b comprise a component-side interface 21 and 22 to the underfloor component, i. to the container of the underfloor component. The interfaces 21 and 22 between

Underfloor component 1 and fastener are preferably standardized. In one embodiment, standardized interfaces are of the same type and independent of any other factors, such as the type of components to be connected or the particular installation situation. This means in particular that the standardized interface between underfloor component and fastener according to

Embodiments always the same, regardless of the different

Fasteners and to be fastened underfloor component.

The first fastening element 2a also has a first interface 23 to the car body 10, and the second fastening element 2b has an interface 24 to the car body 20. These are carriage box-side interfaces. The interfaces 23, 24 may be the same in the described system, but need not be. In the example shown in Figure 2, the fasteners 2a and 2b are attached by means of a suspension on the car body 10, or 20. In another example, the fasteners may be attached to the carbody by means of C-rails, for example become. The attachment of the fasteners on the car body can generally be done depending on the car body type.

As shown in Figure 2, the first fastening elements 2a differ from the second fastening elements 2b. According to one embodiment, the fastening elements 2a and 2b differ by the position of the interfaces. For example, in FIG. 2 it can be seen that the interface 21 of the first fastening element 2a to the underfloor component 1 has a vertical distance 30 to the interface 23 of the first

Attachment 2a to the car body 10 has. However, the interface 22 of the second fastening element 2b to the underfloor component 1 has a vertical distance 40 to the interface 24 of the second fastening element 2b to the car body 20, which is different from the distance 30. This makes it clear that the fasteners are different according to embodiments, which may affect both the shape and the size of the fasteners.

The car bodies 10, 20 shown in FIG

Embodiment produced by an extrusion process, through which the

Providing an interface to a fastener already at

Manufacturing process can be considered. For example, a C-rail may be provided integrally with the carbody. In another embodiment, the interface of the car body can be made separately to the fastener and then firmly connected to the car body, for example by screwing a C-rail to the car body.

Between the underfloor components 1 and the car bodies 10, 20, or between the container and the car body, a distance is provided in each case. Thus, the underfloor components or containers together with the car body limit a cavity for receiving at least one cable channel, fluid lines or supply and / or disposal lines.

FIG. 3 shows a further embodiment of a modular system. The modular system comprises an underfloor component 1, four first fastening elements 2 and side skirts 3a and 3b of the rail vehicle, which are held on the first fastening elements 2 and load-bearing by the fastening elements 2 by means of an interface. In another embodiment, the underfloor component is such

equipped that they can hold the side skirts of the rail vehicle, in which case the combination of underfloor component and side skirts together of the

Fastening element is held load-bearing on the car body.

The side skirts 3a and 3b may serve as a side cover for the rail vehicle, for example. In one embodiment, the fastening element and / or the underfloor component may have a receptacle or interface for a bottom plate. When using the system for attaching an underfloor component is therefore no additional (support) structure for the additional components, such as

Side skirts and bottom plates, needed.

The side skirts 3a and 3b can be chosen flexibly in shape, height and length and can optionally with air ducts and / or electrical

Be equipped supply lines. The attachment of the side skirts, for example, by a joint, by extrusion profiles of the side skirts and on

Attachment (or on the underfloor component), and / or done by a C-rail in the vehicle longitudinal direction. For sealing the one shown in FIG

Underfloor construction, an additional sealing surface 4 may be provided. In the event that the underfloor structure is not to be provided with side skirts, or in the case of a high IP class of the rail vehicle, the underfloor component itself may be equipped with separate aprons or distributor components 5.

FIGS. 4a to 4c show different views of a modular system 100 for fastening an underfloor component to the wagon body of a rail vehicle. The system 100 includes an underfloor component 1 and four first fasteners 2c, 2d, 2e and 2f as described above. In the embodiment shown in FIGS. 4 a to 4 c, the fastening elements are identical on a respective lateral side of the underfloor component. Accordingly, in Figure 4a, the first

Fixing elements 2c and 2d equal, while the first fastening elements 2e and 2f differ from these, but are also the same to each other. Here, for example, the respective installation situation and the respective space conditions on the

different car bodies of rail vehicle types and / or the respective

Installation situation and the respective space conditions on the different lateral sides of a car body of a rail vehicle type are taken into account, without having to adapt the underfloor component. FIG. 4a shows an example in which the fastening elements 2c and 2d have a different vertical fastening height allow as the fasteners 2e and 2f. The pointing in the direction of the car body mounting interfaces of the fasteners 2c, 2d, 2e and 2f, which are exemplified here schematically as flat surfaces, may be spaced in the vertical direction of the underfloor component. In this way, in the assembled state, a cavity between underfloor component and car body, the

Accommodation of cable ducts or supply lines is suitable.

FIGS. 4a and 4b show by way of example how the side skirts 3a and 3b are attached to the fastening elements 2c and 2f. The side skirts 3a and 3b have in the example shown on ventilation slots, which can provide, for example, a ventilation of the underfloor component or can be used for the air supply of the rail vehicle interior. In the figures 4b and 4c also the sealing surface 4 can be seen, which ensures a seal of the underfloor component 1.

In the figure 4c is particularly good, the different installation height of

Underfloor component 1 can be seen, which can be achieved by the selection of the corresponding first and second fasteners, while the interfaces between fasteners and underfloor component is standardized.

FIG. 5 shows an exploded view of a modular system 100 for fastening an underfloor component according to embodiments. With the modular system shown in a set in Figure 5, it is possible to use a system with maximum flexibility with respect to different installation situations, especially when using the same underfloor component with a defined, standardized interface and the like or the same Design for different vehicle types.

The underfloor component 1 can be designed the same for different types of vehicles, or be provided in a container of the same size and shape. After providing the underfloor component 1, depending on the vehicle type and installation situation, the fastening element or the fastening elements 2c, 2d, 2e and 2f can be selected. As described above, the fasteners have a standardized interface to the underfloor component. In the example shown in Figure 5, the underfloor component without adaptation of the underfloor component by selecting the corresponding fasteners to a car body with

be installed at different installation heights. For example, in the example shown in FIG. 5 for the one carbody side with a lower installation height Fasteners 2c and 2d chosen for the other car body side with a larger installation height, the fasteners 2e and 2f are selected. The design of the fastener is selected accordingly, for example, based on the size and shape of the fastener.

In Figure 5, after mounting the fasteners on the

Underfloor component still side skirts 3a and 3b and / or a bottom plate 6 are attached to the fasteners. A sealing surface 4, which can be attached to one of the fasteners or to the underfloor component itself, allows sealing of the underfloor component, for example, against ingress of moisture or dirt. A separate skirt 5 may be directly attached to the fasteners or to the underfloor component suitable for this purpose

Can have shots, which forms a cladding-side interface.

The underfloor component 1 can also have a container in the form of a partially open frame construction. In this case, for example, the skirt 5 form a side wall of the container. The side skirt 3b then serves here only as outwardly visible side panel of the rail vehicle. Alternatively, the

Side skirt serve both as a side panel of the rail vehicle and as a side wall for lateral closure of the container. This dual function is taken over, for example, by the side skirt 3a.

Both the side skirt 3b and the side skirt 3a can be pivotally attached to the container or to the respective fastening elements 2c, 2d, 2e, 2f.

In one embodiment, the fasteners and the

Underfloor component together described as underfloor unit, which can be adapted to different car bodies of rail vehicles. The adaptation takes place exclusively by the selection of the corresponding fasteners from a group of fasteners, as has been described above in detail, for example. Typically, the underfloor component and / or the fasteners of the underfloor unit in embodiments may have the features described above.

In one embodiment, a rail vehicle has a

Underfloor component, which is held by a fastener carrying a laser. In this case, the fastener from a group of fasteners with different sizes and / or shapes selected to adapt to

different car body types to make at the same time standardized connection of fastener and underfloor component. The above-described examples of features for the underfloor component and the fasteners may also find application in this embodiment.

With the modular system according to embodiments, the

Attachment function between car body and underfloor component of the

Car body relocated to the underfloor unit. This makes it possible for the

To offer underfloor components, their housings, or containers or boxes containing the underfloor component in a standardized manner, i. in a way that is the same for all vehicle types. The adaptation to the different car bodies

different vehicle types (for example, an adaptation to different

Carriage widths) then takes place by means of fastening element, in particular by selecting a suitable fastener. In previously known systems, this was achieved, for example, via mounting beams, which, however, resulted in a loss of installation space in the vehicle longitudinal direction.

Thus, the modular system for attaching an underfloor component provides an interface to the underfloor component that is independent of the underfloor component

Carriage design is (for example, regardless of the position of a long-carrier) and independent of the underfloor cross-section. The structure and the fixation for side skirts and bottom plates may be formed as parts of. The modular system offers a flexible application and can be adapted to different cross sections with a high reuse value for technical solutions and components. Among other things, this results in shorter development time, a proven and reliable design, a reduction in costs and a reduction in life cycle costs.

In particular, it is with the modular system for fixing the

Underfloor component possible, a standardized design for all variants of

To provide undercarriages of rail vehicles. It can in

Embodiments be standardized both the underfloor component and the interface between the underfloor component and fastener. The standardized interface can be implemented independently of the design of the underfloor of the car body. The above-described embodiments may be arbitrarily combined with each other. While specific embodiments have been illustrated and described herein, it is within the scope of the present invention to properly modify the illustrated embodiments without departing from the scope of the present invention. The following claims are a first, non-binding attempt to broadly define the invention.
