This makes it possible to manufacture the underfloor components in a standardized manner regardless of the specific type of car body, which saves manufacturing costs.
  • the adaptation to the load-bearing fastening of the underfloor component to the different car bodies is made by selecting the fastening elements adapted to the respective car body. This means that the same fastening system can be used for different car body types or projects.
  • the underfloor component can also have further interfaces, for example electrical interfaces, hydraulic interfaces, or pneumatic interfaces.
  • the standardized design of a certain underfloor component for example, especially for different types of car body, at least as far as the interface to the fastening element is concerned, results in a high reuse effect, since the underfloor components can be used for almost all types of vehicle.
  • the adaptation to different car bodies through the selection of the corresponding fastening elements also allows sufficient flexibility with regard to the car body interfaces to be made available.
  • the fastening elements in embodiments typically have an identical or similar interface to the underfloor components, the interface of the fastening elements to the car body not being specified and, depending on the type of car body, being able to be included in the selection of the fastening elements.
  • a further effect of the modular system according to embodiments is that suppliers can adjust to the standardized components and thus costs can be reduced.
  • the same interfaces and the same or similar design of the underfloor components also reduce the installation effort and thus the installation costs.
  • a uniform size can be specified for a specific underfloor component for different vehicles in a rail vehicle fleet.
  • the size specification can relate to the container of the underfloor component. By specifying the size by the rail vehicle manufacturer, the latter can control and optimize the arrangement and the space requirements of the individual underfloor components, whereby a better use of space can be achieved.
  • the fastening elements can typically be detachably connected to the container of the underfloor component and the car body, which ensures easy interchangeability.
  • the fastening elements are used in particular for load-bearing fastening of the respective underfloor component to the car body, i. that is, the fasteners support the weight of the underfloor component.
  • Further load-bearing elements for example cross members attached to the car body, are not required and can be saved, whereby the available installation space is increased.
  • the underfloor components are therefore preferably fastened to the car body without such cross members.
  • the containers can furthermore have carrier elements which form an inner support structure of the container and which carry the interfaces on the container side. The interfaces are then part of the support structure. Side walls of the container can also be attached to the support frame.

  • the containers can have the additional inner support structure or only the side walls.
  • the support frame alone forms the container, i.e. it is open.
  • the containers of different underfloor components have a standardized width, ie in the transverse direction of the car bodies, but different lengths, ie in the longitudinal direction of the car bodies.
  • the standardized width can be configured identically for a vehicle fleet, ie a large number of different vehicles.
  • the standardized width preferably corresponds to a width which is also suitable for installation in the narrowest vehicle in the vehicle fleet, in particular the maximum possible width for installation in the narrowest vehicle with a given clearance profile.
  • the floor of the container can form the floor panel of the vehicle.
  • the floor panels of a vehicle fleet can have the same width.
  • the containers are preferably the same, but they can be different in the other dimension, i.e. in the longitudinal direction.
  • the same fastening elements are therefore required for fastening different containers, and thus underfloor components, to the same type of car body.
  • the first and second fasteners are therefore the same.
  • the modular system can 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 specific vehicle are the side skirts as well as the fastening elements.
  • 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 design. Due to the flexible design of the size and / or shape of the fastening elements, an adaptation to different geometries of the car bodies is possible. For example, by adapting the size and shape of the fastening elements, the position of the interface between the fastening element and the car body can be varied.
  • 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 in relation to the interface to the underfloor component. This makes it possible to simultaneously provide a standardized or the same interface between the fastening element and the underfloor component and to enable assembly on different car bodies.
  • the selection of the respective fastening elements results in an adaptation to the car body size and / or the car body shape and / or the height of the car body floor.
  • the adaptation to the size or shape of the car body can only be done by selecting the appropriately shaped ones, saving time and money.

  • the fastening system can be further simplified and the assembly costs can be reduced.
  • Fastening to the car body by means of C-rails offers easy to assemble and flexible positioning of the underfloor components on the car body.
  • the first and / or second fastening elements have at least one further interface for fastening a side panel for the rail vehicle.
  • the fastening parts can be designed to support the weight of the side panel.
  • no separate structure is required for the side cladding, which reduces both the manufacturing costs and the assembly costs due to the reduced assembly effort.
  • the reuse effect of the system is also improved by the fastening element, which can take over the fastening function for several components of the rail vehicle.
  • a floor plate can also be made available for the rail vehicle, the floor plate being releasably attachable to the underfloor component, for example. Corresponding interfaces can be provided on the underfloor component. Overall, the system described thus offers a construction that can dispense with additional supports for side skirts and / or floor panels, which also has a positive effect on reducing the weight of the rail vehicle.
  • the container of the underfloor component has a further interface for attaching a side panel for the rail vehicle, the side panel closing the container laterally.
  • the side cladding can thus take on both the function of the outer closure of the container and the function of the side cladding of the rail vehicle.
  • the container is therefore open per se without this side panel, at least on this side.
  • side panels adapted in each case can be provided for different vehicles.
  • the receiving space under the car body for receiving the underfloor component can be formed by the container and the side paneling adjoining the container.

Between the area adjoining the container and the side wall of the vehicle, the side paneling in the narrowest vehicle in a vehicle fleet preferably runs essentially in a straight line, while the side paneling in wider vehicles is essentially curved in a bulbous manner. In the case of wider vehicles, the receiving space is therefore larger than that of narrower vehicles.
  • the side cladding is visible from the outside and, for example, takes on the function of aerodynamic air ducting and cladding.
  • a bottom panel for closing the container on its underside can be attached to the support frame of the container and / or to the fastening elements.
  • the side panel can be attached in an articulated manner, for example by means of a hinge, regardless of whether it is attached to one or two fastening elements and / or to the container, so that when the side panel is opened, access to the container or the components located in the container is made possible at the same time .
  • the container can form part of the underfloor structure of the rail vehicle, i.e. the side paneling, for example in the form of side skirts, can be attached to the container, for example by means of hinges.
  • the container can be open on the side and closed solely by the side skirts, or, if there are special requirements for sealing or for the supply of filtered air, it can have its own side walls.
  • the container can form a fastening structure for a base plate.
  • the underbody of the container can preferably form the base plate.
  • the height of the sub-floor can be adjusted using the individualized fastening elements.
  • the fastening elements can form bulkheads in order to control or prevent the air flow to the box (if the underfloor component requires filtered air) or to create fire protection.

  • the modular system that is included in Figure 5 is shown in a set, it is possible to use a system with maximum flexibility with regard to different installation situations, especially when using the same underfloor component with a defined, standardized interface and a similar or the same design for different vehicle types.
  • the underfloor component 1 can be configured identically for different types of vehicles, or can be provided in a container of the same size and shape.
  • the fastening element or fastening elements 2c, 2d, 2e and 2f can be selected depending on the vehicle type and installation situation.
  • the fastening elements have a standardized interface to the underground component.
  • the underfloor component can be mounted on a car body with different installation heights without adapting the underfloor component by selecting the appropriate fastening elements.
  • fastening elements 2c and 2d For one side of the car body with a lower installation height, for example, the in Figure 5 example shown the Fastening elements 2c and 2d selected, for the other side of the car body with a greater installation height, fastening elements 2e and 2f are selected.
  • the design of the fastening element is selected accordingly, for example on the basis of the size and shape of the fastening element.
  • side skirts 3a and 3b and / or a base plate 6 can be attached to the fastening elements.
  • a separate apron 5 can be attached directly to the fastening elements or to the underfloor component, which can have receptacles suitable for this purpose, which form an interface on the cladding side.
  • the underfloor component 1 can also have a container in the form of a partially open frame construction.
  • the skirt 5 can form a side wall of the container.
  • the side skirt 3b then serves here only as a side panel of the rail vehicle that is visible to the outside.
  • the side apron can serve both as a side panel of the rail vehicle and as a side wall to close off the container at the side. This double function is taken over, for example, by the side skirt 3a.
  • Both the side skirt 3b and the side skirt 3a can be pivotably attached to the container or to the respective fastening elements 2c, 2d, 2e, 2f.
  • the fastening elements and the underfloor component are described together as an underfloor unit that can be adapted to different car bodies of rail vehicles.
  • the adaptation takes place exclusively through the selection of the corresponding fastening elements from a group of fastening elements, as described in detail above, for example.
  • the underfloor component and / or the fastening elements of the underfloor unit can have the features described above in embodiments.
  • a rail vehicle has an underfloor component which is held in a load-bearing manner by a fastening element.
  • the fastener is from a group of fasteners with different sizes and / or shapes selected in order to adapt to different types of car body with a standardized connection of fastening element and underfloor component at the same time.
  • the above-described examples of features for the underfloor component and the fastening elements can also be used in this embodiment.
  • the fastening function between the car body and the underfloor component is shifted from the car body to the underfloor unit.
  • This makes it possible to offer the underfloor components, their housing, or the container or box containing the underfloor component in a standardized way, i.e. in a way that is the same for all vehicle types.
  • the adaptation to the different car bodies of different vehicle types (for example an adaptation to different car body widths) then takes place by means of a fastening element, in particular by means of selecting a suitable fastening element. In previously known systems, this was achieved, for example, by means of mounting bars, which, however, resulted in a loss of installation space in the longitudinal direction of the vehicle.
  • the modular system for fastening an underfloor component thus provides an interface on the underfloor component that is independent of the car body design (for example, independent of the position of a longitudinal girder) and independent of the underfloor cross-section.
  • the structure and the fixation for the side skirts and floor panels can be designed as parts of the.
  • 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. This results, among other things, in a shorter development time, a tried and tested and reliable design, a cost reduction and a reduction in life cycle costs.
  • both the underfloor component and the interface between the underfloor component and the fastening element can be standardized.
  • the standardized interface can be designed independently of the design of the underfloor of the car body.
