TECHNICAL FIELD

[0001] The utility model relates to a kind of covering assemblies, especially for rail vehicles, the covering assembly has at least first covering and at least one connecting device, the connecting device is used to connect covering assembly with at least one at least partially to be covered equipment, especially for connecting covering assembly with at least partially to be covered chassis for rail vehicles or / and with at least partially to be covered carriage for rail vehicles;And the utility model relates to a kind of rail vehicles. BACKGROUND

[0002] For example in the field of rail vehicle technology, there is generally a need for mass-reduced mechanical components. It is also generally required to meet ecological evaluation criteria for manufacturing and using components, vehicles, etc. Lightweight parts, such as covering for rail vehicles, can be implemented, for example, in aluminum material, glass fiber material or carbon fiber material.

[0003] From the prior art, for example, WO 2014 / 206643 A1 is known, in which document a rail vehicle with a covered chassis is shown. The covering assembly comprises a plurality of covering parts.

[0004] Furthermore WO 2019 / 120508 A1 discloses a covering assembly for a vehicle, which covering assembly has an emergency stop device.

[0005] Furthermore in WO 2019 / 161888 A1 a covering assembly for a vehicle is described, which covering assembly has a bearing device with at least three bearings.

[0006] Furthermore EP 2368781 A1 shows a crash protection for a chassis of a rail vehicle, wherein the element absorbing the crash energy can be constructed in wood material. SUMMARY

[0007] The task on which the utility model is based is to propose a further improved covering assembly with reduced weight compared to the prior art.

[0008] According to this invention, the task is solved using the covering assembly described herein, which has at least a first cover and at least one connecting device for connecting the covering assembly to at least one device to be covered, wherein the first cover is constructed of a layered material having wood or made of wood, and wherein the at least one connecting device is connected to the first cover. The layered material can be, for example, a veneer material made of wood or a composite material, in which at least one wood layer is connected to at least one metal layer (e.g., an aluminum layer). This results in a lightweight cover that also possesses high structural strength, damping characteristics, and a suitable geometry. A high degree of environmental sustainability and recyclability is also achieved. Furthermore, the covering assembly enables low-resistance flow within its area.

[0009] Further advantageous designs of the cover component according to this invention are described below.

[0010] Another advantageous design of the cover component according to this utility model includes:

[0011] The layered material is functionalized, thereby giving at least one first cover fire resistance; at least one first cover has a varying wall thickness; at least one first cover is constructed in a curved manner or with a varying slope; at least one first cover is at least partially covered with metal; at least one first cover is at least partially covered with aluminum; the at least first cover has at least one coupling region for connecting the at least one connecting device to the at least first cover, wherein, in the at least first coupling region, at least one first metal insert is engaged in at least one recess of the at least first cover; the at least first insert is arranged to at least partially abut against a portion of the at least first cover offset from the at least first... The cover has a base or top surface; a force-transmitting locking structure and a material locking structure are constructed between at least a first insert and at least a first cover; at least a first insert has at least one hole for a threaded part or pin; at least a first insert is constructed of aluminum; the cover assembly is for a rail vehicle, and the connecting device is provided for connecting the cover assembly to at least a partially covered chassis of the rail vehicle and / or to at least a partially covered car of the rail vehicle; the rail vehicle has at least one cover assembly according to the present invention; at least one chassis of the rail vehicle and / or at least one car of the rail vehicle is at least partially covered by at least one cover assembly.

[0012] When layered materials are functionalized, the risk of fire and combustion is reduced, thereby making at least the first covering fire-resistant. Functionalization of layered materials can be achieved, for example, by impregnating the layers with a fire retardant (e.g., a phosphate-based fire retardant salt for impregnating wood materials, having a certificate of conformity according to DIN 4102-1, B1 – “non-flammable” and a classification report according to EN13501-1 (B-s2 / s1, d-0), suitable for transport applications); or by chemically modifying the layered material (e.g., by charring the surface of the layers), etc.

[0013] When at least the first cover has a varying wall thickness, the strength and vibration characteristics of the first cover are improved.

[0014] To improve the aerodynamic characteristics of the cover assembly, it is beneficial to at least construct the first cover in a curved manner or with a varying slope.

[0015] When at least the first cover is at least partially covered with metal, it is possible to achieve a strong shroud and / or high shape accuracy of the first cover. If the cover assembly is used, for example, on a rail vehicle, then it is possible to cover the first cover with metal in one or more areas where the spacing for net space constraints is small, etc.

[0016] A lightweight housing of the first cover is achieved when at least the first cover is at least partially covered with aluminum.

[0017] When at least the first cover has at least a first coupling region for connecting at least one connecting device to at least the first cover, the cover assembly achieves stable characteristics in terms of connection technology (e.g., for connecting the cover assembly to a rail vehicle), wherein, in at least the first coupling region, at least one metal first insert is engaged in at least a first recess of at least the first cover.

[0018] An advantageous solution is achieved when at least the first insert is arranged to at least partially abut against a surface of at least the first cover that is offset from the base or top surface of the first cover. This measure results in precise positioning of the first insert within the first recess. Furthermore, the first insert can thus be arranged, for example, sunken within the first recess, thereby avoiding, for example, sharp protrusions of the first insert, and / or reducing the weather-related sensitivity of the first cover and / or the first insert.

[0019] When a force-transmitting locking structure and a material locking structure are formed between at least a first insert and at least a first cover, a redundant connection is obtained between the first insert and the first cover.

[0020] For coupling the cover assembly (e.g., coupling it to a rail vehicle), it may be advantageous, for example, for at least the first insert to have at least one hole for a threaded part or pin.

[0021] A lightweight metal implant is achieved when at least the first implant is constructed using aluminum.

[0022] Rail vehicles equipped with at least one cover assembly according to the present invention can open up promising application areas for the cover assembly according to the present invention.

[0023] When at least one chassis and / or at least one car of a rail vehicle is at least partially covered by at least one covering component, aerodynamic improvements and / or lightweight encapsulation can be achieved in the chassis area and / or in the car area. Attached Figure Description

[0033] Figure 9 A flowchart of an exemplary variant embodiment of a method for manufacturing a cover component according to the present invention is shown. Detailed Implementation

[0034] Figure 1 It shows how to use as in Figure 8 The image shows a perspective view of the bottom side of a first cover 1, an exemplary first variant embodiment of a cover assembly according to the present invention, for a rail vehicle. The first cover 1 is configured as a component for the bottom cover of the chassis 7 of the rail vehicle. By means of the first cover 1, the bottom side of the chassis 7 can be covered in the area of ​​the first wheel set 8 of the chassis 7 and the area of ​​the first drive unit of the chassis 7 (not shown).

[0035] The first covering 1 is made of wood and has multiple layers (in) implemented as a veneer material (Furnierschichtwerkstoff). Figure 3 The example illustrates a layered material comprising a first layer 10, a second layer 11, and a third layer 12.

[0036] To meet the necessary fire protection requirements for rail vehicles (e.g., according to European Standard (EN) 45545, Hazard Class (HL) 2), each layer of the veneer material is impregnated with a non-toxic and environmentally friendly fire retardant (a known phosphate-based fire retardant salt for impregnating wood materials; inspection certificate DIN 4102-1, B1 - "non-flammable"; classification report according to EN13501-1 (B-s2 / s1, d-0); suitable for transport applications). The layered material is thus functionalized, thereby giving the first cover 1 fire resistance.

[0037] These layers are achieved through methods such as combining Figure 9 The exemplary manufacturing method describes bonding the components together under pressure and simultaneously forming the desired profile.

[0038] The first cover 1 is partially curved and partially constructed with varying slopes. For example, a first segment 13 of the first cover 1 has a curvature, a second segment 14 of the first cover 1 has a first slope, and a third segment 15 of the first cover 1 has a second slope, wherein the first slope and the second slope have different angles of inclination. Furthermore, the first cover 1 is partially covered in a metallic manner using an aluminum sheet. An aluminum cover, for example, is disposed in a fourth segment 16 of the first cover 1.

[0039] Furthermore, the first cover 1 includes at least a first coupling region 17, a second coupling region 18, and a third coupling region 19, wherein in the first coupling region 17, a first insert 21 of the cover assembly made of aluminum metal is inserted into a first recess 24 of the first cover 1, and wherein in the second coupling region 18, a second insert 22 of the cover assembly made of aluminum metal is inserted into a second recess 25 of the first cover 1.

[0040] As also Figure 6 As exemplarily illustrated, the first metal insert 21 is implemented as an aluminum bracket, which is threadedly connected to the first cover 1. Additionally, the first insert 21 is bonded into the first cover 1. Thus, a force-transmitting locking structure and a material-locking structure are formed between the first insert 21 and the first cover 1. The second metal insert 22 is constructed identically to the first insert 21 in terms of material, manufacturing principle, and functionality. The first cover 1 can be connected to the first sway support device (also referred to as a sway stabilizer) of the rail vehicle via the first coupling region 17 and the second coupling region 18.

[0041] As in Figure 7 As exemplarily illustrated, in the third coupling region 19, the first metal profile 27 and the second metal profile 28 of the cover assembly are threadedly connected to the first cover 1. The first metal profile 27 and the second metal profile 28 are connection devices for connecting the cover assembly to the chassis 7, through which the first cover 1 can be connected to the first drive unit of the chassis 7.

[0042] exist Figure 2 The diagram shows how to use it as in Figure 8The image shows a top-side perspective view of an exemplary second variant embodiment of the cover assembly according to the present invention for a rail vehicle chassis 7. The cover assembly includes a first cover 1, a second cover 2, and a third cover 3, which form a bottom cover for the chassis 7. The cover assembly can cover the bottom side of the chassis 7. Here, the first cover 1 can be arranged below the first wheel set 8 of the chassis 7 and below a first drive unit (not shown) of the chassis 7, the second cover 2 can be arranged below the second wheel set 9 of the chassis 7 and below a second drive unit (not shown) of the chassis 7, and the third cover 3 can cover the bottom side of the chassis 7 between the first wheel set 8 and the second wheel set 9. The first cover 1, the second cover 2, and the third cover 3 are implemented using a veneer material made of wood, such as in combination with... Figure 1 and Figure 3 As exemplified in the description.

[0043] The first cover 1 has a first coupling region 17 and a second coupling region 18 for a first swing support device for a rail vehicle. Figure 6 The first coupling region 17 is described in detail. The second coupling region 18 is constructed identically to the first coupling region 17 in terms of its structural principles, manufacturing technology principles, and functional principles. The first cover 1 and the first swing support device can be coupled through the first coupling region 17 and the second coupling region 18.

[0044] Furthermore, the first cover 1 includes a third coupling region 19, through which the first cover 1 can be connected to the first drive unit of the chassis 7. Figure 7 The third coupling region 19 is described in detail.

[0045] Combination Figure 1 The first cover 1 is described in detail. The second cover 2 is implemented in the same way as the first cover 1 in terms of its structural principles, manufacturing technology principles, and functional principles.

[0046] Similar to the first cover 1 and the second cover 2, the third cover 3 is constructed of a veneer material made of wood, such as in combination with... Figure 1 As exemplarily described. In the fourth coupling region 20 of the third cover 3, the third cover 3 is connected to a first cover 30 of the partial metal of the cover assembly, and in other coupling regions of the third cover 3, the third cover 3 is connected to a cover of another partial metal of the cover assembly.

[0047] The third cover 3 can be connected to the chassis frame of the chassis 7 (not shown) via the first cover 30 and the additional cover, thus the first cover 30 and the additional cover are connection devices for connecting the cover assembly to the chassis 7.

[0048] In an alternative variant implementation, the covering assembly can also be connected to the carriage 31 of the rail vehicle to be covered by means of a first cover 30, wherein the first cover 30 acts as a connecting device for connecting the covering assembly to the carriage 31.

[0049] Combination Figure 4 The first cover 30 is described in detail.

[0050] The first cover 30 and the other cover are implemented according to the same principle in terms of their connection function between the third cover 3 and the chassis frame.

[0051] In response to such Figure 8 The rail vehicle shown in the example is... Figure 3 A partial side view of an exemplary third variant embodiment of the covering assembly according to the present invention is shown in cross-section. The covering assembly includes a first cover 1, a second cover 2, and a third cover 3, as shown in... Figure 2 As exemplarily shown in, where, as in Figure 1 As exemplarily illustrated, in the first coupling region 17 of the first cover 1, the first metal insert 21 of the cover assembly is inserted into the first recess 24 of the first cover 1, and in the second coupling region 18 of the first cover 1, the second metal insert 22 of the cover assembly is inserted into the second recess 25 of the first cover 1. Through the first cover 1 in... Figure 1 The third coupling region 19, as exemplarily shown, is capable of such... Figure 7 The first metal profile 27 and the second metal profile 28 of the cover assembly, which are exemplarily shown, are coupled to the first cover 1 for connecting the first cover 1 to a first drive unit (not shown) of the chassis 7 of the rail vehicle.

[0052] Figure 3 A third metal insert 23 of the cover assembly is shown, which is inserted into a third recess 26 of the third cover 3 in a fourth coupling region 20 of the third cover 3. The third insert 23 enables the insertion of... Figure 2 and Figure 4 The first cover 30 of the metal portion shown in the example is connected to the third cover 3 for connecting the third cover 3 to the chassis frame of the chassis 7.

[0053] The third insert 23 is arranged to abut against the surface 33 of the third cover 3, which is offset from the base surface 32 of the third cover 3.

[0054] The third insert 23 is constructed as an aluminum bracket and is threadedly connected to the third cover 3 by means of a first countersunk threaded member 34, a second countersunk threaded member 35, and another countersunk threaded member in conjunction with a threaded bushing. Alternatively, the third insert 23 is glued into the third cover 3. Thus, a force-transmitting locking structure and a material-locking structure are formed between the third insert 23 and the third cover 3. Therefore, in the event of a failure of the first countersunk threaded member 34, the second countersunk threaded member 35, and / or another countersunk threaded member, the third cover 3 remains in position. Furthermore, the third insert 23 includes a first through hole 36 with a first recessed portion, a second through hole 37 with a second recessed portion, and another through hole with a further recessed portion, through which the first cover 30 can be connected to the third cover 3. A threaded member or pin can pass through the first through hole 36, the second through hole 37, and the other through hole.

[0055] The third cover 3 is implemented using a layered material of wood, which is a veneer material. To meet the necessary fire resistance requirements for rail vehicles (e.g., according to European Standard (EN) 45545, Hazard Class (HL) 2), the first layer 10, the second layer 11, the third layer 12, and the remaining layers of the veneer material are impregnated with a non-toxic and environmentally friendly fire retardant (known phosphate-based fire retardant salts for impregnating wood materials; inspection certificate DIN 4102-1, B1 - "non-flammable"; classification report according to EN 13501-1 (B-s2 / s1, d-0); suitable for transport applications). The layered material is thus functionalized, thereby giving the third cover 3 fire resistance.

[0056] The first layer 10, the second layer 11, the third layer 12, and the other layers are combined as follows Figure 9 The exemplary manufacturing method describes bonding the materials together under pressure and simultaneously forming the desired profile.

[0057] In response to such Figure 8 The rail vehicle shown in the example is... Figure 4 A perspective view, shown in cross-section, is an exemplary fourth variant embodiment of the cover assembly according to the present invention. The cover assembly includes a first cover 1, a second cover 2, and a third cover 3, as shown in... Figure 2 As exemplarily illustrated in [the example]. Furthermore, the overlay component has, as in [the example]... Figure 1 and Figure 2 The first coupling region 17, the second coupling region 18, and the third coupling region 19 shown in the example are as follows: Figure 2 and Figure 3 The fourth coupling region 20 is illustrated in the example. Furthermore, the covering component includes, as shown in...Figure 1 The first insert 21 and the second insert 22 shown in the example, as well as those also shown in the example Figure 3 The third insert 23 is shown as an example.

[0058] The third insert 23 is connected to the third cover 3. A partially metal first cover 30 is connected to the third insert 23, through which the third cover 3 can be coupled to the chassis frame of the rail vehicle chassis 7. The first cover 30 includes a multi-bent sheet metal structure 38, through which the first cover 30 is connected via a first threaded member 39, a second threaded member 40, and... Figure 4 An additional threaded component, not visible in the middle, is threadedly connected to the third cover 3. A first metal spacer 41 is arranged between the plate structure 38 and the third cover 3, through which the first threaded component 39 and the second threaded component 40 are guided. A second spacer 42 of the first cover 30 is arranged protruding upward from the plate structure 38. This second spacer is constructed of an elastomer and covers the threaded pin 43 of the first cover 30, which also protrudes upward from the plate structure 38. A flange nut 44 of the first cover 30 is arranged on the threaded pin 43. In the gap region 45 of the threaded pin 43 located between the second spacer 42 and the flange nut 44, the first cover 30 can be coupled to the chassis frame.

[0059] The third covering element 3 is implemented using a veneer material made of wood, such as in combination with... Figure 1 and Figure 3 As exemplified in the description.

[0060] The third cover 3 has a varying wall thickness. Therefore, the third cover 3 has a greater wall thickness in the first region of the third insert 23 compared to outside the first region (in...). Figure 4 In the second region shown next to the first region on the left, the third cover 3 has a smaller wall thickness compared to the first region.

The cover assembly is configured as a bottom cover for a chassis 7 of a rail vehicle. The cover assembly includes a first cover 1 having a first coupling region 17 through which the first cover 1 is connected to a first swing support device of the rail vehicle. In the first coupling region 17, for example, a coupling is formed... Figure 1 and Figure 3 The first insert 21 of the metal, as exemplarily described, is inserted into the first recess 24 of the first cover 1.

[0063] A metal bearing bracket 48 is threadedly connected to the first insert 21, and the bearing bracket is arranged to project upward from the first cover 1. The bearing bracket 48 has a cylindrical opening 49 into which the resilient bearing 50 for the torsion bar of the first swing support device is inserted. The bearing bracket 48 is a connecting device for connecting the cover assembly to the chassis 7, since the first swing support device can be connected to the chassis 7.

[0064] The first covering 1 is implemented using a veneer material made of wood, such as in combination with Figure 1 and Figure 3 As exemplified in the description.

[0065] exist Figure 7 China is targeting such Figure 8 The rail vehicle illustrated herein shows a partial perspective view of an exemplary sixth variant embodiment of the cover assembly according to the present invention. The cover assembly includes a first cover 1 having a first coupling region 17 and a second coupling region 18, as shown in... Figure 1As exemplarily shown in the example. Furthermore, the first cover 1 includes a third coupling region 19 through which the first cover 1 can be connected to a first drive unit (not shown) of the chassis 7 of the rail vehicle. In the third coupling region 19, a first metal profile 27 and a second metal profile 28 of the cover assembly are clamped to the first cover 1 by a threaded connection. A third metal profile 29 is also threaded to the first metal profile 27 and the second metal profile 28. The third metal profile 29 is placed on the first metal profile 27 and the second metal profile 28. The first metal profile 27, the second metal profile 28, and the third metal profile 29 are constructed in a strip-like manner and arranged to project upwards from the first cover 1. The third metal profile 29 hinges on the first swing support 51 and the second swing support 52. The first drive unit can be hingedly coupled to the first swing support 51 and the second swing support 52. The first metal profile 27, the second metal profile 28, the third metal profile 29, the first swing support 51, and the second swing support 52 are connecting devices used to connect the cover assembly to the chassis 7.

[0066] The first covering 1 is implemented using a veneer material made of wood, such as in combination with Figure 1 and Figure 3 As exemplified in the description.

[0067] Figure 8 A partial side view of an exemplary variant embodiment of a rail vehicle according to the present invention, having a carriage 31 and a chassis 7, wherein the carriage 31 is supported on the chassis 7. The chassis 7 includes a first wheel set 8 and a first drive mechanism (not shown) driving the first wheel set 8, and a second wheel set 9 and a second drive mechanism (not shown) driving the second wheel set 9.

[0068] The chassis 7 and the carriage 31 are partially covered by an exemplary seventh variant embodiment of the covering assembly according to the present invention. Figure 8 Invisible and as in Figure 2 The first cover 1, the second cover 2, and the third cover 3 of the cover assembly, as exemplarily shown, form the bottom cover of the chassis 7. The fourth cover 4 of the cover assembly forms the side covers of the chassis 7.

[0069] The roof area of ​​carriage 31 is equipped with the components of carriage 31. Figure 8 The invisible top cover equipment is covered by the fifth cover member 5 of the cover assembly to cover the top cover area. The carriage 31 is arranged in the floor area of ​​the carriage 31. Figure 8The invisible base plate equipment is covered by a sixth cover 6 of the cover assembly. The sixth cover 6 acts as a baffle cover for the rail vehicle. The fourth cover 4 and the sixth cover 6 are located below (facing) Figure 8 (In the image plane) it curves. The fifth cover 5 is on top (towards) Figure 8 (In the image plane) it is curved. However, according to the present invention, it is also conceivable that the fourth cover 4, the fifth cover 5 and / or the sixth cover 6 are at least segmentally constructed with inclined surfaces of different tilt angles, etc.

[0070] The first cover 1, the second cover 2, the third cover 3, the fourth cover 4, the fifth cover 5, and the sixth cover 6 are implemented using veneer materials made of wood, such as in combination with Figure 1 and Figure 3 As exemplified in the description.

[0071] Figure 9 The following are examples of methods for manufacturing such as in Figures 1 to 8 The flowchart illustrates an exemplary variant implementation of the method for covering components according to the present invention.

[0072] In the first method step 53, the layers of the laminated material, made of wood and implemented as a veneer, are impregnated with a fire retardant to functionalize the laminated material. For this purpose, each layer is immersed in an aqueous solution containing the impregnating agent (a known phosphate-based fire retardant salt for impregnating wood materials; inspection certificate DIN 4102-1, B1 - "non-flammable"; classification report according to EN13501-1 (B-s2 / s1, d-0); suitable for transport applications). This achieves fire resistance for the covering assembly. Then, in the second method step 54, an adhesive is applied to the layers. In the third method step 55, the layers are treated with steam, particularly water vapor, to shape them into a profile. For this purpose, the layers are steam-treated (bedampfen) using a steam generator.

[0073] In step 56 of the fourth method, the layers are bonded together under pressure using an extrusion tool to form a contour. The layers are placed into the extrusion tool, which has the contour. The contour can be, for example, curved or straight, or include straight lines with different angles of inclination. When thin layers are used in the method, complex three-dimensional surfaces can also be formed. Radius of curvature of several millimeters can also be achieved by using local, temporary modifications (e.g., treating the layers with water vapor as described in conjunction with step 55 of the third method).

[0074] It is also conceivable that steps 55 of the third method and 56 of the fourth method are executed simultaneously or alternately.

[0075] Then, in step 57 of the fifth method, the layer is connected to the connecting device to connect the covering component to the device to be covered. Following... Figure 9 In this exemplary variant implementation of the method, the connecting device is as follows: Figure 6 The bearing support 48 is illustrated in the example. The layer is connected to this bearing support 48 by, for example, in... Figure 6 The first insert 21 of the metal shown is threaded. In accordance with... Figure 9 In this exemplary variant implementation of the method, the device to be covered is as follows: Figure 8 The example shown is the chassis 7 of a rail vehicle. However, it could also be the carriage 31 of a rail vehicle, etc.
