Component, in particular for an outer lining of a road-bound vehicle

The invention relates to a component, in particular for an outer lining of a path-bound vehicle, an arrangement, in particular for a road-bound vehicle, and a method for producing a component, in particular for an outer cladding of a tied-down vehicle.

It is known in practice that profiled components which are part of an outer lining of a vehicle which is bound away as a rail vehicle must be installed precisely between adjacent components of the outer lining of the rail vehicle. This requires the component

dimensionally accurate, ie with small or vanishingly small error tolerances. Furthermore, it is necessary that the component has a high mechanical stability, in order to redirect if necessary power flows between adjacent to the component further components of the outer lining, which can represent force-carrying components.

A manufacturing method of such a component may be based on a three-dimensional (3D) milling process in which a compact three-dimensional plate is milled to the required dimensions of the component. However, this manufacturing method can be associated with a large amount of time required machine hours of the 3D milling device used and a high material consumption due to the machining process. Consequently, the manufacturing process can be costly.

Another manufacturing method of the component can be based on a casting process in which the component can be cast in one step, for example, aluminum. However, this production method can also be complicated and expensive. It is an object of the present invention to provide measures by means of which a simple and cost-effective production of a component, in particular for an outer lining of a tied-down vehicle, is made possible.

This object is achieved by a component, in particular for an outer lining of a path-bound vehicle, an arrangement, in particular for a road-bound vehicle, and a method for producing a component, in particular for an outer lining of a path-bound vehicle, according to the independent claims. Preferred embodiments of the invention are specified in the subclaims. According to the invention, a component is provided, in particular for an outer lining of a path-bound vehicle, wherein the component is formed by extrusion from solid material, wherein the component has an outer profiling on an outer surface of the component, wherein a first end face and one of the first end face opposite, second end face of the component transversely, in particular perpendicular, extend to the outer surface and wherein the first end face and the second end face are formed by means of milling or sawing.

In the context of the present application, the term "lane-bound vehicle" may in particular denote a vehicle fixed in its direction of travel or its lane, In particular, the vehicle may be (exclusively) bi-directionally movable.

The term "outer lining" may in particular designate an outer shell whose wall may be formed in particular by means of the component.

The term "external profiling" of the component may in particular designate a shaping of a surface of the component Groove, a hole and / or inclined or beveled surfaces.

In a production or production of a component according to the invention, the component, in particular three-dimensionally formed, can be produced with its outer profiling arranged on an outer surface by extrusion from a solid material. This can enable a particularly cost-effective and simple production of the component in only one work step without unnecessary material consumption. In an adjoining, easy to carry out operation, the component can be cut to a first and second face by cutting or sawing dimensionally accurate, so are cut in one of its dimensions, for example in its length, width or height, to the component in particular dimensionally accurate to adjust its dimensions required for installation. The cutting process is carried out by a two-dimensional (2D) machining process, which can be carried out with little effort. As a result, the component can be provided with the necessary connections or connection surfaces for adjacent components.

Overall, the component can be made particularly cost-effective and simple, and it can be avoided in particular in the manufacture of the component, a cost-intensive casting process or a costly three-dimensional milling process.

Furthermore, the component can have easily manageable material properties, for example a sufficient bending flexibility, in particular in comparison to a casting production method for its further processing and / or assembly, due to the extrusion production method used.

In particular, the first and second end faces may extend transversely, in particular perpendicularly, to a base surface of the outer surface of the component which, for example, in FIG Cross-section of the component, by an outer edge, in particular an edge, the outer surface may be defined. The component may have an elongate body, wherein the outer surface may be a longitudinal surface of the body, wherein the first end surface and the second end surface may be transverse surfaces of the body. Alternatively, the first end face and the second end face may represent further longitudinal surfaces of the body which may extend transversely, in particular perpendicularly, to the outer surface.

The outer profiling can have a recess which can be introduced into the outer surface and extend from the first end face to the second end face. The first and second end faces can consequently have lateral apertures which can represent lateral openings for the recess. The recess may be introduced, for example, for optical reasons, for aerodynamic reasons and / or reasons of stability in the component. An extension of the recess from the first end face to the second end face can bring about a uniform outer profiling of the component along an extension direction of the component, so that the component can be manufactured by extrusion in great length, and then cut to size accordingly by sawing or milling become.

The recess may taper towards an interior of the component, wherein a first boundary wall of the recess extending from the first end face to the second end face is concavely curved and a second boundary wall of the recess extending from the first end face to the second end face is flat can be trained. This measure can enable a particularly simple production of the component by means of extrusion molding, since the first and second boundary wall can be geometrically simply shaped. A first depth of the recess, which may be measured from a first outer edge portion of a recess bounding edge to a bottom of the recess, may be different from a second depth of the recess measured from a second outer edge portion of the edge to the bottom of the recess is. The term "edge" may in particular be understood to mean an edge or edge surface.The term "bottom" may be understood to mean, in particular, a point, a line or a surface which is furthest from the first and second edge section along a depth direction Seen recess can be arranged spaced. In particular, the first and second depths may be measured along a common direction. The first depth may be smaller or larger than the second depth.

This measure can have the effect that the component can have different broad sections, as seen in a direction that can run transversely, in particular perpendicular to the depth direction of the recess. As a result, the component can enable a width adaptation between adjacent, differently wide components, in particular the outer panel of the path-bound vehicle. Furthermore, the component can allow a deflection of a force flow between the differently wide sections of the component and / or the components adjacent to these sections.

In particular, a first portion of the outer surface may be disposed adjacent to the first boundary wall of the recess and include the first edge portion, and a second portion of the outer surface may be disposed adjacent to the second boundary wall of the recess and have the second edge portion. The first and second sections may be formed in particular flat and have different inclinations with respect to a common reference surface. This allows the component along the

Extension of the recess may be uniform, so that the extrusion process of the component are carried out particularly inexpensively. The component may have a further outer profiling on a third end face of the component, wherein the further outer profiling may have a welded structure, which may have a chamfer on an outer edge portion of the third end face and a groove-shaped further recess adjacent to the chamfer in the third end face may be introduced, wherein the chamfer and the groove-shaped further recess may extend from the first end face to the second end face. In particular, the weld structure can serve as a weld preparation for a subsequent welding process, by means of which the component can be connected to an adjacent component by means of welding. In this case, welding material of a welding seam to be formed can be introduced into the groove-shaped further recess in order to allow root formation for the weld seam to be formed. In particular, the welding material for the weld to be formed can be placed on the chamfer, in order to enable a welding of the component with the adjacent component in the region of the chamfer. A welding device used can apply heat to the third end face in the area of the chamfer in order to apply sufficient heat transfer to the material of the weld to be formed, the component and the adjacent component. As a result, a particularly stable connection of the component to the adjacent component can be made possible.

The welding structure may have an even further recess in the third end face, wherein the still further recess may be introduced on a side of the groove-shaped further recess facing away from the chamfer in the third end face and extend from the first end face to the second end face. The still further recess may, for example, have a rectangular cross section, which may be substantially constant along a depth extension of the still further recess. As a result, a heat required for the welding process can be bound in the region of the chamfer and the groove-shaped further recess and not in an interior of the component are derived, so that the risk of Flankenbindefehlern in the weld can be greatly reduced. In particular, the component can have an even further external profiling on a fourth end face of the component, which can be designed in accordance with one or more embodiments of the further external profiling of the third end face described above. In particular, the fourth end face may face the third end face. As a result, the component can be connected on both sides with adjacent components.

In particular, the outer profiling and the welding structure of the further outer profiling or the welding structure of the still further outer profiling can be arranged adjacent to one another on a common side half of the component. In particular, the further outer profiling and / or the still further outer profiling can have an even further welded structure which can be arranged on the third end face and / or the fourth end face and formed according to one of the embodiments described above. In particular, the further welding structure and the still further welding structure can be free of the still further recess of the external profiling.
