The present invention relates to a vehicle cabin, in particular a vehicle compartment for a rail vehicle, according to the preceding part of the scope of the utility model registration claim.

In manufacturing the vehicle compartment of known construction, a complete support frame is first constructed by welding each frame member comprising a window frame and a door frame, and then a sandwich member which forms an outer shell in the thus-made unfinished compartment. And the inner lining of the reinforcement.

This is known, for example, from EP-A-O 260 200. Such a construction method requires the preparation of costly assembly means, for example, for the production of unfinished (a) compartments, and on the other hand the latter (back) attachment to the support frame with the recesses and the inner cladding. Attaching planing is a laborious or costly process, which results in disadvantageous manufacturing costs.

An object of the present invention relates to a vehicle compartment capable of manufacturing the above-described vehicle compartment of a simple manufacturing means and low operating costs.

This problem is solved by the vehicle compartment described in the specific section of claim 1 of the utility model registration requester of the present invention.

In the present invention, the support frame member is inserted into each sandwich structure as an integral structural member before assembling the compartment, and disposed in the frame member so that the structural member including the connecting member is accurate at the final assembly position between the cover layers. Since the inner support frame and the compartment sandwich plate of the compartment are no longer separated from each other, they are no longer required to be assembled by means of expensive manufacturing means and also by means of assembling means having a large space. Moreover, whenever necessary, compartment modules according to the present invention with installed interior materials can be manufactured by separating them from the final assembly position in the most rational manner using a simple and easily bent molded adhesive device, and the connecting members By assembling, the vehicle compartment can be configured quickly and easily, which greatly reduces manufacturing means and operating costs.

The shape of the present invention, which is characterized by simply (without problem) assembling each compartment module, has a fitting connection (fixing connection) according to claim 2 of the Utility Model Registration, and is composed of plug coupling members. The coupling members are connected to each other so as to transfer the load after they are fitted, in particular bonded to each other by the utility model claim 3.

5. The utility model registration claim of claim 4, wherein each compartment module is completely enclosed by a support frame member having a fitting engagement member at its edge, thereby extending the fitting engagement member of the support frame over the entire outer edge of the compartment module. While uniform and coupled with high load stability, a clean edge seal for each sandwich structure is achieved in a very simple manner.

Since the specific gravity of the support frame structure is small and the configuration of the fitting coupling or the plug coupling member is very simple, the support frame members according to the Utility Model Registration Claim 5 can be inserted into the hollow part of the compartment module by being precisely inserted into each other. Hollow profile parts are formed.

The support frame members according to the Utility Model Registration Claim 6 are each compartment, in order to facilitate positioning of each support frame member on the exact opposite side when manufacturing each compartment module, because the structure is very solid. It is coupled to each other in the form of a grid in the interior of the module, and is joined by an inflatable fastening screw clamping for easy assembly according to the Utility Model Claim.

When manufacturing the compartment module according to the Utility Model Registration Claim.

When the support layer portion is not exactly limited, this support layer portion can be further reduced, in particular by joining between the frame members of the compartment module via an adjusting adhesive. Especially. The support layer portion consists of a honeycomb core or a foamed material that is elastically adapted to the required bending process very simply without the cost of changing the model when making a bent compartment module.

According to another feature of the invention according to the Utility Model Registration Claim 9, the window and door frame profiles of the vehicle are incorporated in each compartment module in the same way as the support frame member, whereby The cost of assembly is greatly reduced in the area of the window and door parts, since the cover layer is squared in accordance with the window frame and door frame profile only after completion of each compartment module in accordance with the Utility Model Claims Claim 10 to make manufacturing easier. It is not necessary to cut the cover plate in advance in the cutouts of windows and doors.

The cover layer according to the utility model registration claim 11 is preferably composed of a composite fiber layer adhered in a plane with the support frame member,

If you need to locally strengthen the adhesive bonds,

In addition, in accordance with paragraph 12 of the Utility Model Registration Claim, additional clamping may be made from place to place.

Finally, when manufacturing the compartment module according to claim 13 of the utility model registration, at least as a cover layer outer plate, a pre-cured composite fiber thin plate is used, whereby, for example, a support frame member of a honeycomb core attachment plate And other sandwich inserts are prevented from adhering to the outer or inner side of the compartment module, and the vehicle needs to carry out an internal plate waiting for additional assembly after or after costly surface machining (eg by grinding). You will get a smooth surface inside and out.

An embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

The rail vehicle cabin shown in FIG. 1 is composed of pre-fabricated roof, floor, front (not shown) and side wall compartment modules 2.1 to 2.4, each of which is assembled It consists of the support frame of the vehicle compartment comprised in grid form from each support profile member, and the sandwich attachment plate of the support frame which takes in shear reinforcement.

The structure and manufacture of the compartment module will be described based on the side wall partial module with reference to FIG. The compartment module is formed in a sandwich structure having inner and outer cover layers 4 and 6 made of a composite fiber material, and the support profile member of the support frame included in the honeycomb core support layer 8 and the compartment module therebetween. 10 is attached in place as an integral structural member of the sandwich structure.

The support profile member 10 is arranged in a lattice shape so that the outer horizontal and vertical profiles 12 and 14 (support frame members) can form a sandwich structure edge frame in the peripheral (circumferential) direction. have.

In order to manufacture the side wall compartment module a shaped shell (16) consisting of aluminum or steel sheet is used, which is positioned horizontally by the support device 18, on which the first two cover layers ( 4,6) are manufactured and cured into a fibrous layer structure of approximately ± 45 °).

Since the outer surface of the molded cell side of the cover layers 4 and 6 after curing has a very smooth surface structure, it is necessary to attach the residual material in the vehicle at the back of the expensive surface after finishing or on the outer surface of the inner cover layer 4. Can be omitted. The outer cover layer 6 lying on the inclination cell 16 is covered with an adhesive layer such as a phenolic resin layer or a thin film adhesive (not shown), and the support profile member 10 is disposed thereon, and an intermediate space therebetween. There is inserted a force transmitting element, which is the formation of the required insert, for example a lump of glass (not shown). The remaining surface portions (except for the planar portions which remain empty in the windows and doors) are covered with honeycomb core material 8. This material is cut thick to reduce the amount of work, whereby the gaps formed on the support profile member 10 are filled with the adjusting material in the form of an adjusting adhesive or a foam (foaming agent), on which the inner cover layer 4 The sheet is placed again with a thin adhesive or phenolic resin layer interposed therebetween and adhered under pressure and thermal action to make the final compartment module of all components.

The support profile member 10 is prefabricated as a hollow profile made of aluminum or composite fiber material and is already correctly positioned inside the compartment module and tightly coupled to each other before being inserted into the sandwich structure, more specifically in FIG. 3. When the fastening member 22 and the fastening member 22, which are inserted into the open end of one of the support profile members 10 by the inflatable fastening coupling member 20 shown in FIG. Is joined by an inflatable fastening coupling member 20 consisting of fastening screws 24 inserted into the hollow wall of another support profile member 14 via.

The shaping cell 16 is also used to produce a compartment module having a cross-sectional shape in which one side is bent, such as the roof module 2, 1. For this purpose, the shaping cell 16 is fixed to the support device 18 in the resiliently molded state, for example by a suitable profile mold, on which the bent compartment module is identical to the flat compartment module as described above. It is produced by the method, thereby naturally eliminating the need for the support profile member 10 which is naturally bent in advance.

Each compartment module is assembled by means of an accurate subtractive plug coupling member that extends over the entire perimeter of the compartment module to a large area.

For this purpose, the support profile members 12, 14 on the corner side are bonded to the cover layers 4, 6 via a part of the profile width,

It is coupled to transfer load (load) to the edge layer support profile member 12 or 14 of the adjacent compartment module via the profile portion without the cover layer. 4 shows such a mating coupling member between the floor module and the side wall modules 2.2, 2.4.

The double chamber (seal) support profile member 14, which inserts the adjusting adhesive or blowing agent 26 into the intermediate layer to form the outer edge frame of the compartment module adjacent to the honeycomb core 8, has a half of its profile width. Inserted into the sandwich structure only over and tightly coupled to each other by a plug coupling profile 28, which is pressed onto the hollow chamber profile portion without a cover layer and adheres planarly thereto, the coupling profile The free profile leg of 28 is bonded to the cover layer 4.6 of the compartment module 2.2 or 2.4 in an assembled state.

In the fitting connection coupling member between the roof and the side wall modules 2.1 and 2.3 shown in FIG. 5, a hollow chamber profile 30 having one side open is installed as a corner side support profile member of the roof module 2.1. The edge profile 14, 30 is associated, since the free profile leg 32 is likely to be pushed on the edge side facing profile 14 of the side wall module 2.3 during assembly of the compartment modules 2.1, 2.3. The compartment modules 2.1 and 2.3 can be fixed together and bonded together.

The above-described connection coupling members, which consist of edge profile members 12, 14 and 30, which are correctly fitted laterally and bonded together, are similarly connected between the remaining compartment modules, i.e. between the roof module and the side wall module or the intermediate wall module (2.4). It is also used for joining (Fig. 1). In the local stress concentration portion where the adhesive bond strength is not sufficient, the support frame members 10 may further couple each other with nails or screws to the fitting connection coupling member between the cover layers 4 and 6 or the compartment module.

5 also shows the possibility of constructing a compartment module having a different wall thickness relative to the profile height of the edge support profile member. It is formed such that a progressive transition from the thickness of the sandwich structure to the profile height of the edge side support profile member 14 is achieved by inserting a suitable honeycomb core strip 0.2 when producing the compartment module.

As shown in the sixth (a) and the sixth (b) in the same manner as in the support profile member 10, the window and door frame profiles 34 and 36 are also integrated (integrated) in the sandwich structure 2. The visible radius at the edge of the window or door is already formed in the frame profiles 34 and 36, and the extra cover layer material is precisely removed by gluing the sandwich structure 2 and cutting it along the edge of the frame profile. do. A window pane 38 is fixed to the frame profile 34 sequentially with the rubber packing 40 and the corner frame 42. The door frame profile 36 includes a profile portion 44 (sixth (b)) which is integrally molded to form a door stop member.

However, the door frame profile

36 may be selectively formed into two parts along the cutting line shown by the broken line in the sixth (b), and the profile part 44 is only a door frame profile after the side wall module 23 is completed. Can be fixed at 36.

In another method of manufacturing the compartment module, the shaping tool together with the honeycomb core member 8 and the support frame member 10 without having previously cured the cover layers 4 and 6 but instead have not yet cured the cover layers. After being placed on (16, 18), the sandwich structure is bonded and cured at the same time.

In such a case, it is preferable to cover the outer plate by adhering with it at the time of curing the cover layer material by curing the outer plate of at least one cover layer, in particular the inner cover layer 4 in advance.
