Description

TECHNICAL FIELD

[0001] The invention relates to a chassis for a levitation vehicle of a maglev train limited to a track, comprising two rows integrated by a plurality of levitation frames, which are spaced apart from each other in the lateral direction of the chassis and extend in the longitudinal direction of the chassis, wherein the levitation frames of each row adjacent to each other in the longitudinal direction are movably connected to each other by first joints, and a plurality of lateral connections for connecting the two rows, which are each movably connected to two levitation frames opposite to each other in the lateral direction by corresponding second joints. BACKGROUND

[0002] JP4717606B2 discloses a chassis with levitation frames which are connected to each other by longitudinal connections and lateral connections. However, it is not easy to adapt to curves on such a chassis.

[0003] SUMMARY

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

[0005] This object is achieved by a chassis and a levitation vehicle having the features of the independent claims.

[0006] The invention proposes a chassis for a levitation vehicle of a maglev train limited to a track. The levitation vehicle is characterized in that it can hover and glide on the track using magnetic forces, whereby the maglev train can be operated with very low friction.

[0007] The chassis comprises two rows integrated by a plurality of levitation frames, which are spaced apart from each other in the lateral direction of the chassis and extend in the longitudinal direction of the chassis, the two rows of levitation frames corresponding to a track having two rails, the levitation frames may, for example, comprise guide elements for guiding the chassis on the track, and in addition, the levitation frames can have magnets to allow the chassis to be able to hover above the track by magnetic forces.

[0008] In addition, the levitation frames of a row adjacent to each other in the longitudinal direction are movably connected to each other by first joints, whereby the levitation frames of a row can be twisted relative to each other in order to adapt to curves when passing a curve.

[0009] In addition, the chassis comprises a plurality of lateral connections for connecting the two rows, which are each movably connected to two levitation frames opposite to each other in the lateral direction by corresponding second joints, by means of which the levitation frames spaced apart from each other in the lateral direction and / or the two rows of levitation frames can also be twisted relative to each other, whereby the levitation frames or the two rows can also adapt to curves when passing a curve.

[0010] According to the present invention, at least two transverse connectors spaced apart from each other in the longitudinal direction of the chassis are designed to have different lengths. Due to the different lengths of the transverse connectors, the dynamics of the chassis can be improved when cornering. The transverse connector is a transverse connector that connects to the corresponding row of suspension frames at one point. Therefore, each end of the transverse connector is connected to the corresponding row at one point. Using transverse connectors of different lengths can improve the driving dynamics of the chassis, especially when cornering. In this case, the transverse connector can be designed as a continuous component, such as a continuous transverse connector and / or a continuous rod.

[0011] Advantageously, the length of the lateral connectors decreases from the center of the chassis toward the free end of the chassis, thereby generating favorable power when cornering. Therefore, these lateral connectors located on the sides of the chassis all have different lengths starting from the center.

[0012] Advantageously, every two lateral connectors, equidistant from the chassis center in the longitudinal direction, have the same length. The lateral connectors are thus symmetrically arranged with respect to their length about the chassis center, resulting in the chassis having the same driving force when moving forward and backward.

[0013] Advantageously, the chassis and / or lateral connectors include at least one shear plate. Unlike the lateral connectors, which are each connected to the respective row of suspension frames at one point, the shear plate is connected to the respective row of suspension frames at two points. Therefore, the shear plate's degree of freedom of movement is more restricted compared to the lateral connectors.

[0014] Advantageously, the lateral connector includes at least one short connector and at least one long connector, wherein the length of the short connector is shorter than the length of the long connector; advantageously, the short connector and / or the long connector are designed as a continuous assembly, for example, a continuous rod.

[0015] Advantageously, at least one first short connector is disposed in the region of the first end of the chassis and / or at least one second short connector is disposed in the region of the second end of the chassis opposite to the first end, thereby improving driving dynamics.

[0016] Advantageously, each of these lateral connectors connects two laterally subordinate suspension frames to form a suspension frame pair; the two suspension frames of a suspension frame pair can move in coordination when cornering.

[0017] Advantageously, the first and / or second short connectors are the outermost short connectors in the longitudinal direction of the chassis, that is, viewed from the corresponding end of the chassis, the outermost short connector is the first lateral connector, thereby enabling the chassis to adapt to the bending path in the best manner; here, the first and / or second short connectors can be designed as continuous components, such as continuous rods.

[0018] Advantageously, the chassis includes at least one rigid link rigidly connected to at least one suspension frame and preferably having a longer length than the lateral connector; the rigid link may, for example, be located in the central region in the longitudinal direction of the chassis.

[0019] In this way, the two rows of suspended frames can be connected to each other, either through lateral connectors, particularly short and long connectors, or through shear plates, or through rigid links; each lateral connector, particularly short and long connectors, connects to the corresponding row of suspended frames at one point; the shear plates can be connected to the corresponding suspended frames at two points, particularly also through a second joint, so the shear plates are connected to the two rows of suspended frames at a total of four points, namely, to one row at two points and to the other row at two other points. Therefore, compared with the lateral connectors, the shear plates have a greater degree of freedom of movement. The two points where the shear plates are connected to the corresponding rows can be spaced apart from each other in the vertical direction, where the vertical direction refers to the height axis of the chassis when it is intended to be used; by connecting the shear plates to the corresponding rows and the second joint at two points, the shear plates can only move in one direction relative to the corresponding rows.

[0020] Advantageously, all long links and / or rigid links are longitudinally positioned between a first short connector on the first end of the chassis and a second short connector on the second end of the chassis.

[0021] Advantageously, the second joint of the short connector has a hinge distance from the suspension frame in the lateral direction, so that the short connector does not pivot directly on the suspension frame, but is at a hinge distance from the suspension frame.

[0022] Advantageously, the length of the short connector is 90%, particularly 80%, and preferably 70% of the length of the long connector. The chassis can achieve its ideal minimum curve radius based on the length of the connector.

[0023] Advantageously, the first and / or second short connectors are disposed on the suspension frame via spacer assemblies; the spacer assemblies are disposed between the respective short connectors and the respective suspension frames; furthermore, a second joint may be disposed between the short connectors and the spacer assemblies to allow the short connectors to pivot relative to the spacer assemblies; the spacer assemblies may be rigidly disposed on the suspension frame; additionally or alternatively, some spacer assemblies may also be hingedly disposed on the suspension frame.

[0024] Advantageously, the suspension frame has a centerline located in the transverse direction and extending longitudinally through the suspension frame, and in particular, the second joint of the transverse connector, which is a short connector and / or a long connector, is spaced apart from the centerline and / or has the hinge distance; the centerline may also extend through the first joint, and the second joint is therefore spaced apart from the first joint in the transverse direction.

[0025] Advantageously, the second connector can be laterally spaced from the first connector and / or the centerline.

[0026] The present invention also proposes a levitation vehicle for a maglev train, comprising a chassis designed according to at least one of the foregoing and / or the following features.

[0027] Further advantages of the invention are described in the following examples. Attached Figure Description

[0028] Figure 1 A top view of a chassis for a track-bound suspended vehicle, the chassis having short and long connecting members;

[0029] Figure 2 This is a side view of the hovercraft. Detailed Implementation

[0030] Figure 1 A top view of the chassis 1 of a track-bound levitation vehicle is shown. The chassis 1 includes connectors 4 and 5 of varying lengths spaced apart from each other along the longitudinal direction X of the chassis 1. The levitation vehicle 8 is part of a maglev train. The chassis 1 includes multiple suspension frames 2a–2j, by which the chassis 1 and the levitation vehicle 8 can be levitated on a track (not shown), thereby preventing contact between the chassis 1 and the track and allowing frictionless movement. To enable the chassis 1 to levitate relative to the track, at least some of the suspension frames 2a–2j are provided with magnets for lifting the chassis 1 or the levitation vehicle 8. The levitation vehicle 8 is... Figure 2 As shown in the image.

[0031] The suspension frames 2a-2j are set on the longitudinal X and transverse Y of the chassis 1, with the longitudinal X parallel to the driving direction of the suspended vehicle 8.

[0032] In addition, these suspended frames 2a-2j also form two rows 14 and 15 of the suspended frames 2a-2j; in particular, the first row 14 of the suspended frames 2 includes suspended frames 2a, 2c, 2e, 2g, and 2i, while the second row 15 of the suspended frames 2 includes suspended frames 2b, 2d, 2f, 2h, and 2j.

[0033] Suspended frames 2a-2j are movably connected to each other in the longitudinal direction X via first joints 3a-3h. Suspended frames 2a, 2c, 2e, 2g, and 2i are movably connected to each other via first joints 3a, 3c, 3e, and 3g to form the first row 14 of suspended frame 2, while suspended frames 2b, 2d, 2f, 2h, and 2j are movably connected to each other via first joints 3b, 3d, 3f, and 3h to form the second row 15 of suspended frame 2. Each first joint 3a-3h connects two adjacent suspended frames 2a-2j to form the two rows 14 and 15 of suspended frame 2. These first joints 3a-3h are at least partially hinged, allowing the five interconnected suspended frames to adapt to curves.

[0034] The chassis 1 also includes a plurality of lateral connectors 4, 5, of which at least two are designed to have different lengths from each other. These lateral connectors 4, 5 connect the two rows 14, 15 of the suspension frames 2a-2j to each other in the lateral Y direction, and at least some of the lateral connectors 4, 5 are connected to the suspension frames 2a-2j via second joints 7a-7h.

[0035] When the chassis 1 travels through a curve on the track, the suspension frame 2a-2j can pivot relative to the corresponding lateral connectors 4 and 5 via the corresponding second joints 7a-7h.

[0036] In this embodiment, for clarity, the second connectors 7a-7h are shown only on a few transverse connectors 4 and 5. For example, although the second connectors 7 are not shown on transverse connectors 4b and 4f, they may still be present.

[0037] Alternatively or additionally, the chassis 1 may also have at least one rigid link 13. The chassis 1 according to this embodiment includes a rigid link 13 that is rigidly connected to the two suspension frames 2e and 2f, and the rigid link 13 does not have joints 3 and 7.

[0038] Lateral connectors 4, 5 and / or rigid links 13 are also each connected to two suspension frames 2a-2j spaced apart in the lateral Y direction to form a suspension frame pair 6a-6e; when the chassis 1 swings into the curve of the track, the suspension frames 2a-2j of the suspension frame pair 6a-6e pivot towards each other simultaneously through the connection of lateral connectors 4, 5.

[0039] The chassis 1 also has a first end 9 and a second end 10 opposite to it in the longitudinal direction X.

[0040] The transverse connectors 4 and 5 are designed as short connector 5 and long connector 4, respectively. The length of the transverse connectors 4 and 5 can be reduced longitudinally from the center M of the chassis 1 outwards.

[0041] The length of the short connector 5 is shorter than the length of the long connector 4; in addition, the first short connector 5a is disposed at the first end 9 of the chassis 1, while the second short connector 5b is disposed at the second end 10.

[0042] Specifically, the short connectors 5 can be the shortest lateral connectors 4 and 5, which are connected to the suspension frames 2a-2j via second joints 7a-7h. These second joints 7a-7h can form a swing about the height axis of the chassis 1, which is perpendicular to the longitudinal and lateral X and Y axes.

[0043] In the case of short connectors 5a and 5b, the distance between each second connector 7a, 7b and 7g, 7h in the transverse Y direction is less than, for example, the distance in the case of long connectors 4a and 4g; while in the case of long connectors 4a and 4g, the distance between each second connector in the transverse Y direction is greater than the distance in the case of short connectors 5a and 5b.

[0044] The turning ability of chassis 1 can be improved by the first and / or second short connecting piece 5, and the chassis 1's adaptation to the curvature of curves can also be improved by this.

[0045] According to this embodiment, the first short connector 5a is disposed at the outermost first end 9, that is, the first short connector 5a is the outermost lateral connector 4, 5 at the first end 9; according to this embodiment, the second short connector 5b is disposed at the outermost second end 10, that is, the second short connector 5b is the outermost lateral connector 4, 5 at the second end 10; therefore, in particular, all long connectors 4 and / or rigid links 13 are located between the first and second short connectors 5a, 5b; in addition, at least one additional short connector 5 (not shown in the figure) may be disposed between the first and second short connectors 5a, 5b at the first and second ends 9, 10.

[0046] Furthermore, the chassis 1 shown here has spacer components 11a-11d, through which short connectors 5a and 5b are disposed on the corresponding suspension frames 2a, 2b, 2i, and 2j. In this embodiment, each short connector 5a and 5b is assigned two spacer components 11a-11d; of course, it is also conceivable that at least one short connector 5a and 5b is assigned only one spacer component 11a-11d, and thus the at least one short connector 5a and 5b is directly disposed on the suspension frames 2a, 2b, 2i, and 2j and the corresponding suspension frames 2a, 2b, 2i, and 2j in the transverse Y direction via the spacer components 11a-11d.

[0047] With the help of these spacer components 11a-11d, the corresponding second joints 7a, 7b, 7g, and 7h can move inward, that is, move away from the corresponding suspension frames 2a, 2b, 2i, and 2j, thereby improving the turning performance of the chassis 1 when it is in motion.

[0048] As shown in this embodiment, the spacer components 11a-11d can be rigidly mounted on the corresponding suspension frames 2a, 2b, 2i, 2j, and as shown here, the spacer components 11a-11d extend vertically away from the corresponding suspension frames 2a, 2b, 2i, 2j.

[0049] Alternatively, at least some of the spacer components 11a-11d can also be hinged to the corresponding suspension frames 2a, 2b, 2i, 2j.

[0050] Furthermore, the suspension frame 2 has a centerline ML, located at the center of the transverse Y direction and extending in the longitudinal X direction. For clarity, the centerline ML is shown only on the suspension frame 2a here, while the second joint 7 is arranged spaced apart from the centerline ML in the transverse Y direction.

[0051] As shown in the figure, the short connector 5 and / or the long connector 4 can be designed as continuous components, such as continuous rods, so that they can directly transmit force between the respective suspension frames 2.

[0052] Furthermore, the short connector 5 and / or the long connector 4 may not be connected to the rest of the chassis 1, that is, the short connector 5 and / or the long connector 4 are only connected to the two corresponding suspension frames 2, thereby allowing the short connector 5 and / or the long connector 4 to freely transmit forces between the corresponding suspension frames 2. The short connector 5 and / or the long connector 4 can therefore have a higher degree of freedom in their movement, thus enabling the chassis 1 to better adapt to curves. The short connector 5 and / or the long connector 4 are therefore only connected to the suspension frame 2 at their second joint 7, and the short connector 5 and / or the long connector 4 are not further connected to the chassis 1 and / or the carriage 12.

[0053] Furthermore, as shown here, the lateral connectors 4 and 5, which are in particular short connectors 5 and / or long connectors 4, can be directly, but still, connected to the corresponding suspension frame 2 via the second connector 7 and / or via the spacer assembly 11, thereby allowing force to be directly transmitted to the suspension frame 2. In particular, the lateral connectors 4 and 5, which are in particular short connectors 5 and / or long connectors 4, can be directly, but still, connected to the corresponding suspension frame 2 via the second connector 7 and / or via the spacer assembly 11 on both sides, i.e., both sides.

[0054] The spacer assembly 11 and / or the second connector 7 may also be provided on the suspension frame 2, especially directly on the suspension frame, and in particular, the transverse connectors 4 and 5, which are short connectors 5 and / or long connectors 4, are provided on the spacer assembly 11 and / or the second connector 7.

[0055] Figure 2A side view of the suspended vehicle 8, including the chassis 1, is shown. The chassis 1 includes... Figure 1 The suspended frames 2b, 2d, 2f, 2h, and 2j are shown in the figure. The other five suspended frames 2a, 2c, 2e, 2g, and 2i are obscured and not visible in the figure. The chassis 1 is also equipped with a carriage 12, which can transport personnel inside.

[0056] The above figures and the described embodiments are not intended to limit the scope of the present invention. All equivalent changes and modifications made in accordance with the claims of the present invention, even if they are shown and described in different parts of the specification or the claims or in different embodiments, shall still fall within the scope of the patent of the present invention.
