Technical Field

[0001] The present invention relates to a running frame for restraining a levitation vehicle on a track of a magnetic levitation train. The running frame comprises two rows of levitation frames, which are spaced apart from each other in the transverse direction of the running frame and extend in the longitudinal direction of the running frame. The running frame also comprises at least one transverse beam extending in the transverse direction and at least one longitudinal beam extending in the longitudinal direction, wherein the longitudinal beams are connected to the transverse beams. Background Art

[0002] EP0059443A2 discloses a running frame of a magnetic levitation train, which includes spring elements for elastically suspending the carriages. The disadvantage is that the elastic suspension effect is poor. Summary of the Invention

[0003] Therefore, the object of the present invention is to improve the elastic suspension system of the carriages of a magnetic levitation train.

[0004] To achieve the above objectives, the present invention provides a running frame and a suspended vehicle.

[0005] The present invention provides a running frame for a magnetic levitation train track to restrain a levitation vehicle. The magnetic levitation train does not need to be in contact with the track to run, but uses magnetic force to achieve levitation and drive the levitation vehicle.

[0006] The running frame includes two rows of multiple suspension frames, which are spaced apart from each other in the transverse direction of the running frame and extend in the longitudinal direction of the running frame. The suspension frames may include magnets to enable the running frame and the suspension vehicle to be suspended and driven.

[0007] The traveling frame further comprises at least one transverse beam extending in a transverse direction and at least one longitudinal beam extending in a longitudinal direction, wherein the longitudinal beam is connected to the transverse beam.

[0008] Furthermore, at least one transverse elastic suspension element is provided between the longitudinal beam and the transverse beam, so that the longitudinal beam and the transverse beam are elastically suspended relative to each other in the transverse direction, thereby damping, attenuating and / or absorbing transversely acting vibrations.

[0009] In some embodiments, the running frame, in particular the crossbeam, is further provided with a transverse stop for the longitudinal beam to limit the transverse movement of the longitudinal beam. The longitudinal beam can abut against the transverse stop in the transverse direction, so that the transverse movement of the longitudinal beam is limited or guided.

[0010] In some embodiments, the transverse elastic suspension member is arranged between the transverse stop and the longitudinal beam. The transverse stop may be arranged on the transverse beam, so that the transverse elastic suspension member and / or the longitudinal beam can be supported on the transverse stop.

[0011] In some embodiments, the transverse stop is disposed on the crossbeam in a detachable or non-detachable manner. Thus, the transverse stop can be arbitrarily disposed and / or replaced on the crossbeam. In some embodiments, the transverse stop is integrally formed with the crossbeam.

[0012] In some embodiments, the transverse elastic suspension member is arranged on the inner long side and / or the outer long side of the longitudinal beam, so as to achieve buffering on both sides of the longitudinal beam.

[0013] In some embodiments, the longitudinal beam is disposed between the two transverse beams and connected to the two transverse beams.

[0014] In some embodiments, two longitudinal beams are provided between two transverse beams spaced apart from each other in the longitudinal direction.

[0015] In some embodiments, the transverse elastic suspension member is provided at the first end and / or the second end of the longitudinal beam, thereby buffering both ends of the longitudinal beam in the transverse direction.

[0016] In some embodiments, a transverse bolster is disposed between two laterally spaced longitudinal beams, connecting the car body to the running frame. In this case, the transverse bolster is connected at both ends to the two longitudinal beams, thereby supporting the car body on the transverse bolster. To this end, the transverse bolster may be provided with a receiving device, and the car body may be connected to the transverse bolster via a receiving portion or support member.

[0017] In some embodiments, the transverse elastic suspension members on the inner long side and / or the outer long side of the longitudinal beam are arranged on the longitudinal beam via fasteners (particularly fasteners penetrating the longitudinal beam in the transverse direction).

[0018] In some embodiments, the transverse elastic suspension member is connected to the longitudinal beam via screws, wherein the transverse elastic suspension member is preferably provided with a through hole to achieve screw connection.

[0019] In some embodiments, the transverse elastic suspension member is an elastic block (particularly an elastic block made of rubber), thereby realizing a reliable elastic suspension system.

[0020] The present invention further provides a suspended vehicle with a running frame, wherein the running frame has at least one feature described above and / or below. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will now be further explained by means of the following figures and examples.

[0023] Figure 2 : Partial top view of the running frame with transverse elastic suspension parts.

[0026] Figure 1 The diagram shows a top view of a running frame 1 of a levitated vehicle 9. The running frame 1 is particularly suitable for use in magnetic levitation trains, wherein the levitated vehicle 9 is suspended above a track in a contactless manner and is kept suspended and / or driven by magnetic forces.

[0027] The traveling frame 1 includes a plurality of suspension frames 2a-2j, which are spaced apart from each other in the longitudinal direction X and the transverse direction Y. The traveling frame 1 includes two rows (7, 8) of suspension frames 2 spaced apart from each other in the transverse direction Y. Suspension frames 2a, 2c, 2e, 2g, 2i form a first row 7, and suspension frames 2b, 2d, 2f, 2h, 2j form a second row 8. Furthermore, when the suspended vehicle 9 moves forward, the longitudinal direction X is parallel to the direction of travel. In this embodiment, the traveling frame 1 has ten suspension frames 2a-2j, with five suspension frames 2a-2j being provided on each side of the traveling frame 1. Every two suspension frames 2a-2j spaced apart from each other in the transverse direction Y can form a suspension frame pair.

[0028] The levitation frames 2 a - 2 j may include magnets to generate the magnetic force required for levitation and / or driving of the levitation vehicle 9 .

[0029] According to this embodiment, the suspension frames 2a-2j are further connected in the longitudinal direction X by means of longitudinal connectors 5a-5h. The longitudinal connectors 5a-5h can be articulated, allowing the suspension frames 2a-2j to adapt to the curve when traveling on a curved road. The longitudinal connectors 5a-5h respectively connect two adjacent suspension frames 2a-2j in the longitudinal direction X, thereby connecting the suspension frames 2a-2j into two rows (7, 8).

[0030] According to this embodiment, the two rows (7, 8) of suspension frames 2a–2j are connected in the transverse direction Y by transverse connectors 6a–6d. Four transverse connectors 6a–6d are shown here by way of example, but the running frame 1 can also be provided with more than four transverse connectors 6a–6d. The transverse connectors 6a–6d can have hinged connectors so that the suspension frames 2a–2j can also rotate relative to the transverse connectors 6a–6d to adapt to driving on curves. As shown in this embodiment, the transverse connectors 6b and 6c between the two suspension frames 2e, 2f are rigidly connected to the suspension frames 2e, 2f. Therefore, in this embodiment, the two suspension frames 2e, 2f remain parallel to each other even when turning, and / or do not rotate relative to the transverse connectors 6b and 6c.

[0031] The traveling frame 1 also has at least one crossbeam 3a–3d. In this embodiment, the traveling frame 1 has four crossbeams 3a–3d. The crossbeams 3a–3d are spaced apart from each other in the longitudinal direction X and extend in the transverse direction Y. The crossbeams 3a–3d are also connected to two rows (7, 8) of suspension frames 2a–2j. Specifically, each crossbeam 3a–3d is connected to two suspension frames 2a–2j. For example, the first crossbeam 3a is connected to two suspension frames 2a and 2b. The crossbeams 3a–3d are respectively connected to two suspension frames 2a–2j spaced apart from each other in the transverse direction Y.

[0032] The traveling frame 1 further includes at least one longitudinal beam 4a-4d, which is disposed on and connected to the at least one transverse beam 3a-3d. At least two longitudinal beams 4a-4d are spaced apart from each other in the transverse direction Y. The longitudinal beams 4a-4d also extend in the longitudinal direction X.

[0033] According to this embodiment, two longitudinal beams 4a, 4b spaced apart in the transverse direction Y are disposed between two transverse beams 3a, 3b spaced apart in the longitudinal direction X. The transverse beams 3a, 3b and the longitudinal beams 4a, 4b form a first transverse beam system 10a. The traveling frame 1 also includes a second transverse beam system 10b, which includes two transverse beams 3c, 3d spaced apart in the longitudinal direction X, and two longitudinal beams 4c, 4d disposed on the transverse beams 3c, 3d and spaced apart in the transverse direction Y.

[0034] The cross beam systems 10a and 10b each include two cross beams 3 and two longitudinal beams 4. In the cross beam system 10, the cross beams 3 and longitudinal beams 4 are arranged in a parallelogram. The cross beam systems 10a and 10b have substantially the same structure and are spaced apart from each other in the longitudinal direction X.

[0035] For the sake of clarity, features already described in at least one of the preceding figures may not be described again. A feature may also be described for the first time in the present figure or in a subsequent figure. Identical features are given the same reference numerals for the sake of clarity. Subsequent figures may not show and / or label all features, but features shown in one or more previous figures may be present in the present figure or in one or more subsequent figures. Similarly, a feature may be shown and / or labeled for the first time in the present figure or in one or more subsequent figures. Nevertheless, a feature that appears for the first time in one or more subsequent figures may also have been present in the present figure or in a previous figure.

[0036] Figure 2 A partial top view of the traveling frame 1 is shown, wherein only four suspension frames 2a-2d are shown. Figure 1 The top four suspended frames 2a–2d.

[0037] Figure 2The first cross member system 10a shown has two cross members 3a, 3b and two longitudinal members 4a, 4b. Figure 2 The second cross-beam system 10b, not shown, is preferably identical to the first cross-beam system 10a shown. Figure 2 Only the first cross-beam system 10a is shown.

[0038] In addition, at least one transverse elastic suspension member 11 is provided between the longitudinal beam 4 and the transverse beam 3 , so that the longitudinal beam 4 and the transverse beam 3 buffer each other in the transverse direction Y, thereby buffering, reducing and / or absorbing vibrations generated in the transverse direction Y.

[0039] This embodiment shows four transverse elastic suspension members 11a-11d, two transverse beams 3a, 3b, and two longitudinal beams 4a, 4b. Four contact points are provided between the transverse beams 3a, 3b and the longitudinal beams 4a, 4b. Each of the longitudinal beams 4a, 4b is connected to a transverse beam 3a, 3b via its first longitudinal beam end 15 and second longitudinal beam end 16. Furthermore, each of the transverse beams 3a, 3b is supported by a longitudinal beam 4a, 4b. This forms four transverse elastic suspension members 11a-11d.

[0040] The transverse elastic suspension members 11a-11d are disposed between corresponding transverse stops 12a-12d and corresponding longitudinal beams 4a, 4b. The transverse stops 12a-12d are disposed on the transverse beams 3a, 3b. The first and second transverse stops 12a, 12b are disposed on the first transverse beam 3a, while the third and fourth transverse stops 12c, 12d are disposed on the second transverse beam 3b. The transverse stops 12a-12d enable the longitudinal beams 4a, 4b to be elastically supported relative to the transverse beams 3a, 3b in the transverse direction Y via the transverse elastic suspension members 11a-11d.

[0041] The transverse stop 12 also limits the movement of the longitudinal beam 4 in the transverse direction Y. The longitudinal beam 4 can rest against the transverse stop 12, thereby being guided in the transverse direction Y by the transverse stop 12. In this case, transverse stops 12 can be provided on both the inner long side 13 and the outer long side 14 of the longitudinal beam 4, thereby achieving bilateral guidance of the longitudinal beam 4 in the transverse direction Y. Furthermore, if the transverse elastic suspension member 11 is provided between the longitudinal beam 4 and the transverse stop 12, the longitudinal beam 4 is guided in the transverse direction Y with a buffer.

[0042] The longitudinal beams 4a and 4b each have a first longitudinal beam end 15 and a second longitudinal beam end 16. The longitudinal beams 4a and 4b are disposed on the transverse beams 3a and 3b in the region of the respective first and second longitudinal beam ends 15 and 16. The two first longitudinal beam ends 15a and 15b of the longitudinal beams 4a and 4b are disposed on the first transverse beam 3a, and the two second longitudinal beam ends 16a and 16b are disposed on the second transverse beam 3b.

[0043] The longitudinal beams 4a and 4b also have inner long sides 13 and outer long sides 14. The inner long sides 13 face the center (not labeled) of the running frame 1, i.e., inward; the outer long sides 14 face away from the center of the running frame 1, i.e., outward. In some embodiments, when the longitudinal beam 4 is positioned at the center in the transverse direction, the inner long sides 13 and the outer long sides 14 may also be referred to as the first long side 13 and the second long side 14.

[0044] In this embodiment, the transverse elastic suspension members 11a–11d are disposed between the outer long sides 14a, 14b and the transverse stops 12a–12d. The transverse stops 12a–12d are also disposed on the side of the longitudinal beams 4a, 4b facing the outer long sides 14a, 14b. In certain embodiments, the transverse elastic suspension member 11 may be disposed between the inner long sides 13a, 13b and the transverse stop 12, with the transverse stop being disposed on the side of the longitudinal beams 4a, 4b facing the inner long sides 13a, 13b. Thus, the transverse stop 12 is disposed between the longitudinal beams 4a, 4b in the transverse direction Y. For example, if transverse elastic suspension members 11 are disposed on the inner long side 13, the outer long side 14, and the longitudinal beam first and second ends 15, 16, there are a total of eight transverse elastic suspension members 11. In this case, the crossbeam system 10 includes these eight transverse elastic suspension members 11.

[0045] According to this embodiment, a transverse support beam 17 is provided between the longitudinal beams 4a and 4b. The carriage 18 of the suspended vehicle 9 is coupled to the running frame 1 via the transverse support beam 17. In some embodiments, Figure 1 A transverse support beam 17 is also provided between the two longitudinal beams 4c, 4d. Therefore, the first and second transverse beam systems 10a, 10b can be provided with a transverse support beam 17 between the corresponding longitudinal beams 4a-4d.

[0046] The transverse support beam 17 may be provided with receiving devices 19a-19d, by means of which the carriage 18 is supported on the transverse support beam 17. In this embodiment, four receiving devices 19a-19d are provided on the transverse support beam 17. The receiving devices 19a-19d may be pivots or shafts, so that the carriage 18 can be rotatably supported. This allows the carriage 18 to produce a rolling movement, i.e. the carriage 18 can rotate about the longitudinal direction. Therefore, even if the travel path is tilted laterally, the carriage 18 can remain horizontal. The receiving devices 19a-19d may be provided with a receiving portion 20 (in particular in the form of a support member) to support the carriage 18 (see Figure 4 ).

[0047] Figure 3 1 shows a cross-section of the traveling frame 1. For example, the section is located at the second crossbeam 3b and the viewing angle is towards the first crossbeam 3. For the sake of simplicity, features already described in the previous figures are not repeated.

[0048] According to this embodiment, transverse elastic suspension members 11c, 11e, 11f, 11d are arranged along the transverse direction Y on the inner long sides 13a, 13b and the outer long sides 14a, 14b of the two longitudinal beams 4c, 4d, so as to more effectively cushion, reduce and / or absorb vibrations.

[0049] In addition, the inner long sides 13a, 13b and the outer long sides 14a, 14b of the longitudinal beams 4c, 4d are both provided with transverse stops 12c, 12e, 12f, 12d.

[0050] In addition, the running frame 1 further includes at least one first horizontal elastic suspension 21 . Figure 3 Two first horizontal elastic suspensions 21a and 21b are shown in FIG. The first horizontal elastic suspension 21 is arranged between the longitudinal beam 4 (or longitudinal beams 4a, 4b) and the cross beam 3 (or cross beams 3a, 3b), so that the longitudinal beam 4 is buffered relative to the cross beam 3 in the vertical direction Z.

[0051] In some embodiments, the traveling frame 1 further includes a second horizontal elastic suspension 22 . Figure 3 The second horizontal elastic suspension 22 (i.e., the second horizontal elastic suspension 22a, 22b) is arranged between the crossbeam 3 and the suspension frame 2, so that the crossbeam 3 is elastically supported relative to the suspension frame 2 in the vertical direction Z.

[0052] Figure 3 Also shown are receiving devices 19c, 19d. The receiving devices are circular and / or can be configured as a rotating shaft or a pin. The receiving device 19 is provided with a receiving portion 20 for supporting the carriage 18.

[0053] As shown, the receiving means 19 are provided on the transverse bolster 17. The transverse bolster 17 is connected to the longitudinal beam 4 in its middle region, preferably in its center.

[0054] Figure 2 and Figure 3 A beam system 10 is shown. Figure 1 As shown, the beam systems 10a, 10b may have the same structure and include the same features.

[0055] Figure 4 A side view of a levitated vehicle 9 is shown. Five levitated frames 2 of a row (7, 8) of levitated frames 2 can be seen. A carriage 18 is arranged on the running frame 1, and receiving portions 20a, 20b connect the running frame 1 and the carriage 18 together.

[0056] The present invention is not limited to the embodiments shown and described. A person skilled in the art may modify or change the features within the scope of the claims, as well as combine features (even if these features are disclosed and described in different embodiments).
