Description

The present invention relates to a window profile for a rail vehicle according to the preamble of claim 1. Thus, for example, from US 2 690 822 A a window profile for a rail vehicle, comprising window corners, a vertical stop frame, a first horizontal stop frame and a second horizontal stop frame. Also the JP H05 270403 A and the US Pat. No. 3,862,549 have window profiles for rail vehicles to the object.

Rail vehicles form complex multi-component systems whose material composition and structural design are limited by a multitude of different framework conditions. For example, the requirements in terms of safety, reliability, functionality and last but not least cost-effectiveness of the technical implementation in the field of rail vehicle construction represent a multi-faceted challenge which is not encountered in other areas of vehicle construction or only to a lesser extent.

In rail vehicle construction, in the area of window profiles, there are increased design requirements with regard to the load-bearing capacity to be provided in this area, vehicle body rigidity, space requirements and exact fit. In addition, different functionalities must be met in the window area, such as the inclusion of the windows but also the air flow of the ventilation of the vehicle interior.

So far, these functionalities are provided by a plurality of individual different components, which are connected to one another via different joining methods,
to meet the respective design specifications. A simple, inexpensive, compact and integral solution for combining different functionalities in a component in the window region of a rail vehicle is not yet known.

It is therefore an object of the present invention to provide a window component for a rail vehicle, which has an increased integration of functionalities.

This object is achieved by according to claim 1. Particular embodiments of the invention are given in the dependent claims.

According to the invention, a window profile for a rail vehicle, comprising window corners, a vertical stop frame, a first horizontal stop frame and a second horizontal stop frame, which is characterized in that the vertical stop frame consists of a profile which has a receiving area for a climate channel, wherein the Air conditioning duct is an integral part of the vertical stop frame.

By such an inventive design of a window profile, the functionality of receiving the window and the leadership of the supply and / or exhaust air for the vehicle interior are combined in one component in an advantageous manner. This results in an economic utilization of the available space, on the one hand, and on the other weight savings can be achieved, which are advantageous in today's desired lightweight construction of rail vehicles.

Rail vehicles in the context of the invention are vehicles that move on tracks of pairs and / or parallel rails (rail track). This category includes, for example, railways, suburban railways, subways, suspension railways, freight cars, passenger cars, locomotives, railcars and Power cars. Lightweight rail vehicles are rail vehicles.

According to the invention, it is provided that a one-piece or multi-part, preferably extruded, upright profile, which is structurally integrated into the vehicle body shell without additional Beblechung represents the outer contour of the rail vehicle in the window area. As a result, in addition to the task of forming a lateral frame for receiving the window, the profile also assumes structural tasks in vehicle statics.

Particularly preferably, the profile is an extruded aluminum profile. This offers the advantage of a material-saving production while optimizing the microstructure of the material, which contributes to further reducing the vehicle's empty weight due to its low specific weights. Particularly preferably, the profile material is an aluminum alloy of the type EN AW 6005 A.

According to a further preferred embodiment of the invention, to be provided on the window profile window corners are formed so that at least the vertical stop frame and window corners are formed together in one piece. An Anformung can be done for example by suitable mechanical processing methods such as milling.

According to a further embodiment of the invention, it may be provided that at least the vertical stop frame and the window corners to be provided thereon are made of an organic sheet. In the context of the invention, an organo sheet is to be understood as meaning a fiber composite material which represents a specific combination of two or more materials which improves the properties of the individual components, for example a composite of high-strength fibers and a plastic. Here, the fibers have a significant influence on the properties of the composite, such as the strength and rigidity of the material. In particular, under organo sheets are so-called Prepregs based on thermoplastic materials to understand. In turn, prepregs are semi-finished products of continuous fibers, which are introduced unidirectionally or as a fabric in the fiber composite. Suitable fibers may be, for example, glass or mineral fibers, aramid fibers or carbon fibers. Suitable thermoplastics for the production of corresponding organo sheets are, for example, polyetheretherketone (PEEK), polypropylene (PP), thermoplastic polyurethane (TPU), polyamide (PA) or polyphenylene sulphide (PPS).

In the inventively provided receiving area for an air conditioning duct, such as a separate component, for example in the form of a plastic tube or the like may be introduced. However, it is particularly preferred that the air conditioning duct is an integral part of the vertical stop frame and is formed by the receiving area itself. By such an integrative design advantageously the structural weight can be further reduced. The connection piece for the air conditioning duct can be as a component, for example made of a fiber composite material, in the profile or the vertical stop frame or glued.

According to a further embodiment of the invention, it may be provided that the first horizontal stop frame form a haunch profile and the second horizontal stop frame form an outer longitudinal carrier profile of the rail vehicle body. This structural design provides a high rigidity against roof transverse vibrations and thus contributes to the driving comfort to be achieved as well as passive vehicle safety. In particular, it may be provided that the window corners are adapted in their material thickness load and the welding connection to the longitudinal profiles (coving and side member profile) is in the range of low voltages. In addition, it may be provided that between the window corners the Material is milled away and a frameless window used from the outside and glued to the outer skin flush.

In the longitudinal profiles of the solid profile according to the invention, so the upper and lower horizontally extending stop frame, it may further be provided that they are also extruded and pressed sweat fuses and / or milled pockets have to be easier by conventional joining methods, such as welding to connect the vertical profiles. It may be provided that the wall thickness of the longitudinal profiles are thickened only in the areas of high voltage and have a correspondingly reduced wall thickness in the areas of low voltage. As a result, the weight of the corresponding component can be reduced in an advantageous manner.

According to a further embodiment of the invention, it may be provided that the vertical stop frame has an insulating region for receiving an insulating means. As a result, a further functionality, namely the thermal insulation with respect to the outside area can be advantageously combined in the window profile. It may be provided in particular that in the insulating region a Duromerschaum or a metal foam is introduced as an insulating agent. Examples of suitable duromer foams are polyurethane-based, melamine-resin-based or phenolic-resin-based rigid foams. Examples of suitable metal foams are aluminum, zinc, titanium or steel foams, among which aluminum foams are particularly preferred. One advantage of using metal foams is their high stability and low specific gravity, which contributes to the improved structural integrity of the shell structure. At the same time no fire loads are introduced into the shell structure of the rail vehicle when using metal foams as insulating.

According to a further embodiment of the invention, it may be provided that the vertical stop frame has a stiffening lip. It may be provided in particular that the stiffening lip is provided in the receiving area for the air conditioning duct and thus in the direction of the interior of the rail vehicle. The provision of a stiffening lip increases the stability of the vertical stop frame, which can further contribute to the overall stability of the bodyshell structure.
