Description

[0001] Chassis for a track-bound hover vehicle of a magnetic levitation train and hover vehicle

[0002] The present invention relates to a chassis for a track-bound levitation vehicle of a magnetic levitation train, comprising two rows of multiple levitation frames spaced apart in a transverse direction of the chassis and extending in a longitudinal direction of the chassis, and comprising at least two longitudinal cross members spaced apart in the transverse direction and extending in the longitudinal direction, each of which is assigned to one of the two rows and connects at least two levitation frames of the assigned row. Furthermore, the invention relates to a levitation vehicle of a magnetic levitation train with a chassis.

[0003] CN 104859480 A discloses a chassis for a track-bound levitation vehicle of a magnetic levitation train. The chassis comprises crossbeams and longitudinalbeams, with the longitudinalbeam arranged between two levitation frames in different rows. The longitudinalbeams must be connected to the levitation frames by means of crossbeams.

[0004] The object of the present invention is to improve the state of the art.

[0005] The problem is solved by a chassis and a hover vehicle with the features of the independent patent claims.

[0006] A chassis for a track-bound levitation vehicle of a magnetic levitation train is proposed.

[0007] The chassis comprises two rows of multiple suspended frames spaced apart in a transverse direction of the chassis and extending in a longitudinal direction of the chassis. Furthermore, the chassis comprises at least two longitudinal cross members spaced apart in the transverse direction and extending in the longitudinal direction, each of which is assigned to one of the two rows and connects at least two suspended frames of the assigned row to each other.

[0008] The two rows of suspended frames correspond to a track with at least two rails spaced apart in the transverse direction, in particular a reaction rail, a conductor rail, and / or a slide rail. A drive device arranged in at least one of the suspended frames is operatively connected to the reaction rail such that the levitated vehicle of the magnetic levitation train can be driven in a direction of travel or along the longitudinal direction. Furthermore, the suspended frame preferably has at least one support device, which, in operative connection with the track, lifts the levitated vehicle off the track or allows it to hover. The chassis establishes the connection between the levitated vehicle and the track.

[0009] According to the invention, at least one of the longitudinal cross members is integrated into the associated row, so that the longitudinal cross member at least partially overlaps the at least two suspended frames of the associated row in a top view or bottom view of the chassis. The at least one longitudinal cross member extends longitudinally over the two associated suspended frames. The integrated longitudinal cross member and the two associated suspended frames preferably form a common unit. Top view or bottom view is understood to be the view normal to a vertical direction of the chassis. The suspended frames and the longitudinal cross member overlap one another. The integrated arrangement thus results in a very compact component unit. Since the longitudinal cross member overlaps the suspended frames, the force is introduced essentially in the vertical direction, which can prevent the suspended frames from tilting.Any spring action in the chassis advantageously acts primarily in the vertical direction. Furthermore, the integrated design allows for the elimination and / or reduction of additional longitudinal and / or transverse stiffeners within the suspended frame.

[0010] It is also advantageous if the at least one longitudinal cross member integrated into the associated row and the at least two floating frames of the associated row are arranged one above the other in a vertical direction. Advantageously, the longitudinal cross member is vertically spaced from at least one of the floating frames, in particular from at least one drive unit of the floating frames, such that a power unit can be placed between the longitudinal cross member and the drive unit.

[0011] Furthermore, it is advantageous if at least one of the suspended frames has at least one receiving device for receiving at least one of the longitudinal cross members, wherein the receiving device is preferably arranged below a drive device of at least one of the suspended frames. The at least one receiving device creates the connection between the suspended frame and the longitudinal cross member.

[0012] Furthermore, it is advantageous if each of the drive devices has the power unit. Each of the power units provides the power for the associated drive device. This allows neighboring power units and the associated drive units to continue operating in the event of a power unit failure, at least in emergency mode.

[0013] It is also advantageous if the receiving device is arranged on a longitudinal member of the suspended frame and / or on a support device of the drive device, in particular on a yoke of the support device. The longitudinal member and / or the support device thereby forms at least part of the supporting structure of the suspended frame. Additional components for force and / or torque transmission can thus be eliminated.

[0014] It is advantageous if the receiving device has at least one, preferably two, connecting legs spaced apart from one another in the transverse direction for connecting the receiving device to the longitudinal member and / or the support device. Thus, the receiving device can protrude from the at least one longitudinal member and / or the support device along a vertical direction. The longitudinal cross member arranged thereon is thus spaced apart from the at least one longitudinal member and / or the support device.

[0015] It is advantageous if the receiving device has at least one receiving section extending transversely to the at least one connecting leg and / or connecting two of the connecting legs to each other for receiving and / or securing the longitudinal cross member. If the receiving device has two connecting legs, the receiving device is U-shaped. Both connecting legs are arranged on the support device and / or on the at least one longitudinal member.

[0016] Furthermore, it is advantageous if the receiving device forms a receiving cavity with the longitudinal member and / or the support device. Advantageously, the longitudinal members, the support device, the at least one connecting leg, and / or the receiving section form the receiving cavity. The longitudinal cross member and / or the power unit can thus be arranged within the receiving cavity.

[0017] It is also advantageous if at least one of the longitudinal cross members extends longitudinally into the suspended frame, in particular into the receiving cavity, and / or through the receiving device, in particular through the receiving cavity. This allows the longitudinal cross member to be secured within the receiving cavity. The longitudinal cross member can preferably be secured downwards, i.e., toward the receiving section and away from the support device.

[0018] It is also advantageous if at least one spring element extending along the vertical direction of the chassis is arranged on the longitudinal cross member, in particular in the region of at least one end of the longitudinal cross member projecting in the longitudinal direction, and resiliently connects the longitudinal cross member to the suspended frame. It is also advantageous if the spring element comprises a conical and / or layered spring. The spring force of the spring element formed in the vertical direction acts in the vertical direction. It is also advantageous if the transverse and / or longitudinal cross members are designed to be elastic and / or resilient, in particular in a vertical, longitudinal and / or transverse direction. The spring effect of the chassis is preferably achieved exclusively by the spring element arranged between the at least one suspended frame and the longitudinal cross member and / or at least one of the transverse and / or longitudinal cross members.

[0019] Furthermore, it is advantageous if the chassis has at least one transverse cross member extending in the transverse direction, which connects, preferably substantially centrally, the at least two longitudinal cross members of different rows. The two longitudinal cross members and the one transverse cross member form a spring system, in particular a complete one. This eliminates the need for additional components, in particular additional cross members.

[0020] It is advantageous if the crossbeam has at least one connection surface formed perpendicular to the transverse direction, by means of which the crossbeam rests against a side surface of at least one of the longitudinal beams, wherein the at least one connection surface is preferably formed on at least one flange arranged on the end face of the crossbeam. Furthermore, it is advantageous if two of the connection surfaces of the crossbeam are spaced apart from one another in the transverse direction and connect the two longitudinal beams to one another.

[0021] It is also advantageous if at least one of the longitudinal cross members is arranged transversely outside a space spanned between the respective inner surfaces of two suspended frames of different rows spaced apart in the transverse direction.

[0022] It is advantageous if at least one of the floating frames and at least one of the longitudinal cross members of one of the rows are arranged centrally to a common central plane.

[0023] Furthermore, it is advantageous if the chassis has at least one support means for receiving and / or supporting a vehicle cabin of the hovercraft, wherein the at least one support means is preferably arranged at least partially in at least one recess of the crossbeam. The support means is preferably designed as a pendulum support. The pendulum support can be designed such that the hovercraft is rotatable or pivotable about the longitudinal direction.

[0024] It is also advantageous if two of the support means are spaced apart from each other transversely and / or arranged transversely within the intermediate space. The suspended vehicle can thus be easily picked up through the intermediate space using the support means.

[0025] It is also advantageous if at least one support skid is arranged on the receiving device and / or on another receiving device, in particular on an underside. If at least one of the drive devices fails, the hovercraft can be lowered onto the track by means of the support skid. It is also advantageous if the at least one receiving device and / or the another receiving device has at least one stiffening means, which is preferably designed as a stiffening plate, stiffening profile, and / or stiffening rib arranged between the at least one connecting leg and the receiving section.

[0026] It is also advantageous if at least one of the longitudinal cross members is arranged parallel to the floating frames.

[0027] It is advantageous if the floating frames are connected to each other longitudinally by means of longitudinal connections and / or transversely by means of cross connections.

[0028] Furthermore, a magnetic levitation train with a chassis is proposed. According to the invention, the chassis is designed as described above, whereby the aforementioned features can be present individually or in any combination.

[0029] Further advantages of the invention are described in the following exemplary embodiments. It shows:

[0030] Figure 1 is a schematic bottom view of a chassis for a hover vehicle,

[0031] Figure 2 shows a cross-section through the chassis along the section line A -A,

[0032] Figure 3 shows a cross-section through the chassis along the section line B - B,

[0033] Figure 4 shows a cross section through the chassis along the section line C - C and

[0034] Figure 5 is a schematic view of the hover vehicle with landing gear.

[0035] In the following description of the figures, the same reference numerals are used for identical and / or at least comparable features in the various figures. The individual features, their design, and / or mode of operation are usually only explained in detail when first mentioned. If individual features are not explained in detail again, their design and / or mode of operation correspond to the design and mode of operation of the features with the same or identical functions already described.

[0036] Figure 1 shows a schematic bottom view of a chassis 1 for a levitation vehicle 2 (see Figure 5). The chassis 1 is specifically designed for a magnetic levitation train, in which the levitation vehicle 2 hovers contactlessly above a track. The levitation vehicle 2 is held in suspension by magnetic force.

[0037] The chassis 1 comprises a plurality of suspended frames 3a - 3f, which are arranged adjacent to one another in the longitudinal direction X and in the transverse direction Y. The chassis 1 comprises two rows 4, 5 of a plurality of suspended frames 3, which are spaced apart from one another in the transverse direction Y. The suspended frames 3a, 3c, 3e form the first row 4 and the suspended frames 3b, 3d, 3f form the second row 5. The longitudinal direction X is also parallel to a direction of travel when the hovercraft 2 (Figure 5) is moving. In the present exemplary embodiment, the chassis 1 has six suspended frames 3a - 3f, with three suspended frames 3a - 3f being arranged on each side of the chassis 1. With the suspended frames 3a, 3b and / or 3e, 3f, additional suspended frames 3 can be arranged in a row in the longitudinal direction X. Two floating frames 3a - 3f spaced apart from each other in the transverse direction Y can form a floating frame.

[0038] Furthermore, according to the present exemplary embodiment, the floating frames 3a - 3f are connected to one another in the longitudinal direction X by means of longitudinal connections 6a - 6d. The longitudinal connections 6a - 6d can be articulated, so that the floating frames 3a - 3f can adapt to the curve when cornering. The longitudinal connections 6a - 6d each connect two floating frames 3a - 3f that are adjacent to one another in the longitudinal direction X, so that the floating frames 3a - 3f are connected to the two rows 4, 5. Additional floating frames 3 can be arranged at the longitudinal connections 6a, 6b. Additionally or alternatively, additional longitudinal connections 6 can be arranged between the floating frames 3c and 3e and between the floating frames 3d and 3f, which are concealed here, for example.

[0039] Additionally, according to the present embodiment, the two rows 4, 5 of suspended frames 3a-3f are connected to one another in the transverse direction Y by means of cross connections 7a-7d. Four cross connections 7a-7d are shown here as an example, although the chassis 1 may also have more or fewer than four cross connections 7a-7d. The cross connections 7a-7d may have articulated connections so that the suspended frames 3a-3f can pivot relative to the cross connections 7a-7d in order to adapt to the curve when cornering. As shown in this embodiment, the cross connection 7b between the two suspended frames 3a, 3b is rigidly connected to them. In this embodiment, the two suspended frames 3a, 3b thus remain parallel to one another even when cornering and / or do not pivot relative to the cross connection 7b.

[0040] The chassis 1 further comprises at least two longitudinal cross members 8a, 8b spaced apart from one another in the transverse direction Y and extending in the longitudinal direction X. Each of the longitudinal cross members 8a, 8b is assigned to one of the two rows 4, 5 and connects two suspended frames 3c - 3f of the assigned row 4, 5. A first longitudinal cross member 8a connects the suspended frames 3c, 3e of the first row 4. A second longitudinal cross member 8b connects the suspended frames 3d, 3f of the second row 5. Furthermore, the longitudinal cross members 8a, 8b are each integrated into one of the assigned rows 4, 5. The respective longitudinal cross member 8a, 8b forms, with the suspended frames 3c

[0041] - 3f of the associated row 4, 5 form a common unit. The at least one longitudinal cross member 8a, 8b can preferably be arranged at least partially within one of the floating frames 3c - 3f of the associated row 4, 5. The first longitudinal cross member 8a is integrated into the first row 4, so that the first longitudinal cross member 8a, in the bottom view shown here, at least partially overlaps with the two floating frames 3c, 3e of the associated first row 4. The second longitudinal cross member 8b is integrated into the second row 5, so that the second longitudinal cross member 8b, in the bottom view shown here, at least partially overlaps with the two floating frames 3d, 3f of the associated second row 5.

[0042] In the illustrated embodiment, the floating frames 3c - 3f each have a receiving device 9a - 9d. The receiving devices 9a

[0043] - 9d accommodate the two longitudinal cross members 8a, 8b. For this purpose, at least one of the longitudinal cross members 8a, 8b has at least one end 10 projecting along the longitudinal direction X. In the region of these ends 10, at least one of the longitudinal cross members 8a, 8b projects into the respective receiving device 9a - 9d or through the receiving device 9a - 9d. The first longitudinal cross member 8a is connected to the floating frames 3c, 3e of the first row 4 by means of the receiving devices 9a, 9c. The second longitudinal cross member 8b is connected to the floating frames 3d, 3f of the second row 4 by means of the receiving devices 9b, 9d. Furthermore, the chassis 1 has at least one cross member 11. The cross member 11 is arranged essentially centrally on the two longitudinal cross members 8a, 8b. Advantageously, only one cross member 11 is arranged between the two longitudinal members 8a, 8b. The longitudinal members 8a, 8b, together with the cross member 11, form a spring system 12.The crossbeam 11 has two flanges 13 spaced apart from each other in the transverse direction Y, by means of which the crossbeam 11 is connected to the two longitudinal beams 8a, 8b. Thus, the crossbeam 11 connects the two longitudinal beams 8a, 8b of the different rows 4, 5.

[0044] Furthermore, in the illustrated embodiment, each of the levitation frames 3a-3f has a further receiving device 14a-14f. A support skid 15 is arranged on each of the further receiving devices 14a-14f. Using the support skids 15, the levitation vehicle 2 (see Figure 5) can be parked on the track, for example, in the event of a failure and / or when the magnetic force is switched off. Additionally or alternatively, support skids 15 can be arranged on the receiving devices 9a-9d.

[0045] Furthermore, in the illustrated embodiment, a gap 17 is spanned between the respective inner surfaces 16 of the floating frames 3a-3f. The longitudinal cross members 8a, 8b are preferably arranged outside this gap 17. In the illustrated embodiment, for example, the inner surfaces 16 of the floating frames 3c-3f span the gap 17, in which only the cross member 11 and the two cross connections 7c, 7d are arranged. As shown in the illustrated embodiment, no longitudinal cross member 8 and / or only one cross member 11 is arranged in the gap 17.

[0046] In the illustrated embodiment, at least one of the floating frames 3a-3f and at least one of the longitudinal cross members 8a, 8b of the same row 4, 5 are arranged centrally with respect to a common center plane 18. The floating frames 3b, 3d, 3f of the second row 5 and the second longitudinal cross member 8b are arranged centrally with respect to the common center plane 18. The floating frames 3a, 3c, 3e of the first row 4 and the first longitudinal cross member 8a are also arranged centrally with respect to a common center plane, but this center plane has been omitted for clarity.

[0047] Figure 2 shows a sectional view of Figure 1 along section line A-A. Figure 2 shows in particular the sectional view of the floating frames 3d, 3f and the second longitudinal cross member 8b of the second row 5 through the center plane 18 shown in Figure 1.

[0048] The features shown in Figure 2 can be applied in any combination, in addition to or alternatively to the first row 4 shown in Figure 1. It should also be noted that due to the modified representation of Figure 2 compared to Figure 1, some features are more detailed and / or less detailed and / or not shown. Furthermore, some of the features arranged in the background have been omitted.

[0049] In the illustrated embodiment, the two receiving devices 9b, 9d are arranged along a vertical direction Z below a drive device 19 of the respective suspended frame 3d, 3f. The levitating vehicle 2 (see Figure 5) can be driven and / or made to hover by means of the drive device 19. For driving purposes, the drive device 19 has, in particular, an actuator or a stator of a linear motor. So that the levitating vehicle 2 (see Figure 5) can hover over the roadway, the drive device 19 has a support device 20 with a yoke 21. The yoke 21 extends along the longitudinal direction X. Each of the drive devices 19 preferably has its own power unit for providing the operating power. This power unit can, as shown in the illustrated embodiment, be arranged within the drive device 19 and / or below the drive device 19.In the exemplary embodiment shown, each of the floating frames 3d, 3f has at least one longitudinal beam 22. The longitudinal beam 22 can connect several support devices 20 of one of the floating frames 3d, 3f to one another. The yoke 21 of the support device 20 and / or the at least one longitudinal beam 22 represent the supporting structure of the floating frames 3d, 3f. Further attachments of the floating frame 3d, 3f, such as the linear motor, at least one of the receiving devices 9b, 9d and / or at least one of the further receiving devices 14d, 14f, are attached to this supporting structure. In the exemplary embodiment shown, at least one of the receiving devices 9b, 9d and / or at least one of the further receiving devices 14d, 14f is arranged on the at least one longitudinal beam 20.

[0050] As already described above, the second longitudinal cross member 8b extends into the suspended frames 3d, 3f. For this purpose, the receiving devices 9b, 9d, with the at least one longitudinal member 22 and the yoke 21, span a receiving cavity 23. The longitudinal cross member 8b can extend into this receiving cavity 23 in the suspended frame 3d, 3f. The suspended frame 3d, 3f is formed from the drive device 19, the longitudinal members 22, the at least one receiving device 9b, 9d, and the at least one further receiving device 14d, 14f.

[0051] At least one spring element 24 is arranged within the respective receiving cavity 23. The spring element 24 extends along the vertical direction Z. In the illustrated embodiment, the longitudinal cross member 8b is resiliently connected to the floating frames 3d, 3f by means of the at least one spring element 24 by receiving the respective ends 10 via the receiving devices 9b, 9d. The spring elements 24 are designed as conical springs. The section at which the spring element 24 and / or the longitudinal cross member 8b is received on the receiving device 9b, 9d can be referred to as the receiving section 25. Furthermore, in the illustrated embodiment, the further receiving devices 14d, 14f are arranged on the at least one longitudinal member 22. As already described above, at least one of the support skids 15 is arranged on each of the further receiving devices 14d, 14f.The support skids 15 are arranged on an underside 26 of the further receiving device 14d, 14f.

[0052] Furthermore, in the illustrated embodiment, each of the receiving devices 9b, 9d and each of the further receiving devices 14d, 14f has at least one stiffening means 27. In the two receiving devices 9b, 9d, the stiffening means 27 provide the receiving section 25 as a stiffening profile 27. In the two further receiving devices 14d, 14f, the stiffening means 27 provide the underside 26 as a stiffening profile 27. In addition, the further receiving device 14f has the stiffening means 27 as a stiffening plate 27'. This can prevent, among other things, twisting of the receiving devices 9b, 9d and / or the further receiving devices 14d, 14f.

[0053] Figure 3 shows a sectional view of Figure 1 along section line B-B. Figure 3 shows in particular the sectional view through the floating frame 3e of the first row 4 in the region of the receiving device 9c of Figure 1.

[0054] The features shown in Figure 3 can be applied in any combination additionally or alternatively to the second row 4 shown in Figure 1. It should also be noted that due to the changed representation of Figure 3 compared to Figures 1 and 2, some features are more detailed and / or less detailed and / or not shown. In addition, the representation of some of the features arranged in the background has been omitted. As already described above, here too the longitudinal cross member 8a is arranged within the receiving cavity 23 of the receiving device 9c and / or received therein. The spring element 24 connects the longitudinal cross member 8a to the receiving section 25 of the receiving device 9c. In the exemplary embodiment shown, the receiving cavity 23 is spanned by the yoke 21, the longitudinal members 22, the receiving section 25 and two connecting legs 28 of the receiving device 9c.In the embodiment shown, the connecting legs 28 of the receiving device 9c connect the receiving section 25 to the longitudinal beams 22 and / or the yoke 21. The receiving device 9c is thus U-shaped in the cross section shown.

[0055] To stiffen the receiving device 9c, the latter has at least one stiffening means 27 in the illustrated embodiment. In the illustrated embodiment, these are designed as a stiffening profile 27 and two stiffening ribs 27" connecting the stiffening profile 27 to the connecting legs 28. Additionally or alternatively, the stiffening means 27 can be designed as a stiffening plate 27' according to Figure 2.

[0056] In addition, the drive device 19 is shown in more detail in Figure 3. It can be seen that the support device 20 comprises the yoke 21, preferably a U-shaped yoke 21, and two coils. When the coils are energized, a magnetic field is formed in conjunction with the yoke 21, which, in operative connection with the travel path, leads to the levitation of the hovercraft 2 (Figure 5). Furthermore, the linear motor, in particular the active part of the linear motor, is arranged within the support device 20; this, in operative connection with the travel path, leads to the drive of the hovercraft 2 (Figure 5).

[0057] Figure 4 shows a sectional view of Figure 1 along section line C-C. Figure 4 shows, in particular, the sectional view through the two floating frames 3c, 3d and the longitudinal cross members 8a, 8b centrally through the cross member 11 of Figure 1. It should be noted that due to the modified representation of Figure 4 compared to Figures 1, 2, and 3, some features are more detailed and / or less detailed and / or not shown. In addition, some of the features arranged in the background have been omitted.

[0058] The surfaces defined as inner surfaces 16 in Figure 1 are formed in the illustrated embodiment by the magnets of the support device 20. As already described, the longitudinal cross members 8a, 8b are also arranged outside the intermediate space 17 spanned between the inner surfaces 16 of the suspended frames 3a-3f.

[0059] The crossbeam 11 connects the floating frames 3c, 3d to each other, preferably in a displacement-proof manner. For this purpose, the crossbeam 11 has flanges 13 spaced apart from one another in the transverse direction Y. For this purpose, each of the flanges 13 rests against a side surface 30 of the respective longitudinal beam 8a, 8b by means of a respective connection surface 29.

[0060] With the aid of a strut 31, a vehicle cabin 32 of the hovercraft 2 (see Figure 5), which is only partially shown here, can be coupled to the chassis 1. To accommodate and / or support the vehicle cabin 32, in particular by means of the strut 31, the chassis 1 has at least one support means 33. The at least one support means 33 is arranged at least partially in at least one recess 34 within the cross member 11.

[0061] The support means 33 can be designed as a pendulum support on which the strut 31 is received, which in turn supports the vehicle cabin 32. The support means 33 can furthermore also comprise the strut 31. The support means 33, in particular the pendulum support, can be designed such that the strut 31 is rotatable or pivotable about the longitudinal direction X, so that the vehicle cabin 32 can tilt or pivot relative to the chassis 1 about the longitudinal direction X. This rotatable mounting about the longitudinal direction X is illustrated in the illustrated embodiment.

[0062] Figure 5 shows a schematic side view of the levitation vehicle 2 of a magnetic levitation train with the chassis 1 and the vehicle cabin 32. Here, the five levitation frames 3 shown in the side view are shown, each of which is connected to one another by means of the longitudinal connections 6 and / or longitudinal cross members 8. In contrast to the exemplary embodiment in Figure 1, more levitation frames 3 are arranged one after the other along the longitudinal direction X. Advantageously, two further levitation frames 3b, 3c are arranged in a row in the positive longitudinal direction X next to the levitation frames 3a - 3c already shown in Figure 1, which are connected to one another by means of at least one of the longitudinal cross members 8 integrated into the levitation frames 3. The levitation frames are designed according to the previous description of Figures 1 - 4.

[0063] The present invention is not limited to the illustrated and described embodiments. Modifications within the scope of the patent claims are possible, as are combinations of features, even if they are illustrated and described in different embodiments.
