Description

Technical Field

[0001] The present invention relates to a suspension frame for a maglev train suspended on a track, comprising a frame element, at least one magnet unit disposed on the frame element for lifting, carrying, guiding and / or driving the maglev vehicle, and at least one fixed bearing that rigidly connects the magnet unit and the frame element to each other in the longitudinal direction of the suspension frame. Background Technology

[0002] As known from WO2013 / 083757A2, there is material expansion caused by heat in the load-bearing device of the linear motor of the maglev train vehicle, and elastic wedges are used to compensate for the stress generated therefrom. However, the elastic wedges are squeezed together under the pressure generated therefrom. Summary of the Invention

[0003] Therefore, the purpose of this invention is to improve upon the prior art.

[0004] This objective is achieved through the scope of an independently filed patent application.

[0005] This invention proposes a suspension frame for a levitated vehicle of a maglev train that is constrained by a track, the levitated vehicle being held above the track in a levitated state by magnetic force and / or driven by magnetic force.

[0006] The floating frame includes a frame element that serves as the basic architecture of the floating frame.

[0007] The suspension frame also includes at least one magnet unit disposed on the frame element for lifting, supporting, guiding and / or driving the suspended vehicle, the magnet unit being capable of generating a lifting force for lifting the suspended vehicle.

[0008] In addition, the suspension frame has at least one fixed bearing that rigidly connects the magnet unit and the frame element to each other along the longitudinal direction of the suspension frame; the magnet unit is firmly connected to the frame element via the fixed bearing in the longitudinal direction of the suspension frame.

[0009] According to the invention, the suspension frame has at least one movable bearing spaced apart from the fixed bearing in the longitudinal direction of the suspension frame, the movable bearing connecting the magnet unit and the frame element in a manner that allows them to move longitudinally along the suspension frame; through the movable bearing, the magnet unit can move longitudinally relative to the frame element, thereby compensating for the thermal expansion of the magnet unit in the longitudinal direction during the operation of the frame element.

[0010] Advantageously, movable and / or fixed bearings can transmit tension forces for lifting the levitated vehicle from the track of the maglev train between the magnet unit and the frame element. These tension forces are lifting forces for lifting the levitated vehicle off the track, and these tension or lifting forces can resist gravity and act in the height or vertical direction. The movable bearing can therefore be a longitudinal movable bearing. In the vertical direction, the movable bearing is connected to the frame element in such a way that the tension or lifting force can be transmitted to the frame element when the levitated vehicle is lifted.

[0011] Advantageously, at least one movable bearing is disposed in the region of the first suspension frame end; additionally or alternatively, at least one movable bearing may also be disposed in the region of the second suspension frame end opposite to the first suspension frame end, thereby the suspension frame may have at least two movable bearings disposed at the first and second suspension frame ends.

[0012] Alternatively or additionally, a fixed bearing may be disposed at the center of the suspension frame, particularly between the ends of the first and second suspension frames, while the fixed bearing is located between two movable bearings, and the magnet unit is located in a central region, particularly between the two movable bearings, and is rigidly connected to the frame element longitudinally, thereby allowing the magnet unit to expand at its ends during thermal expansion.

[0013] Advantageously, the magnet unit has a main part of a linear motor. This main part preferably has a magnetic core and at least one coil unit that generates a magnetic field from an electric current. This magnetic field can be used to lift, carry, guide, and / or drive the levitated vehicle, and can also be amplified by the magnetic core. This main part can be part of a short-stator asynchronous linear motor. The track can also have a reactive element that, together with the main part, forms the linear motor and interacts with the magnetic field, thereby lifting and / or driving the levitated vehicle.

[0014] Additionally or alternatively, it is advantageous when the suspension frame, in particular the magnet unit and / or frame element, includes at least one fastener for securing the magnet unit to the frame element.

[0015] Advantageously, in at least one movable bearing, the main part can be displaced at least in the longitudinal direction of the suspension frame relative to the frame element; additionally or alternatively, the magnet unit is fixed in a transverse direction to the longitudinal direction on at least one movable bearing and / or a fixed bearing; the movable bearing can therefore only belong to one direction, i.e., the longitudinal direction, so that the magnet unit can move relative to the frame element, while in other directions, especially in the direction perpendicular to the longitudinal direction, the magnet unit can also be rigidly connected to the frame element in at least one movable bearing.

[0016] Advantageously, the magnet unit has a support unit on which the main part and / or at least one fixing member are disposed, the support unit being designed as a support plate; furthermore, the support unit can also be moved longitudinally relative to the frame element in at least one movable bearing; additionally or alternatively, the support unit can be rigidly connected longitudinally to the frame element on at least one fixed bearing.

[0017] Advantageously, at least one fastener is connected to the frame element at an end region away from the main part; furthermore, at least one fastener may extend away from the main part, particularly in an orthogonal manner.

[0018] Advantageously, the fastener, particularly in its end region, has a connector by which the fastener can be connected to the frame element. The connector can be, for example, a pin, which is arranged on the fastener in a longitudinal orientation.

[0019] Advantageously, the frame element has at least one groove into which a connector for connecting the magnet unit to the frame element can be inserted, wherein the connector can preferably be connected to the frame element by a screw; a pin, as the connector, can be inserted into the groove extending longitudinally in the frame element; since both the groove and the pin in the groove are oriented longitudinally, the pin can move longitudinally in the groove; however, the pin can also be fixed in the groove in the vertical direction, thereby transmitting tensile force.

[0020] In addition, the connector can be securely connected to the frame element in the groove via screws.

[0021] Advantageously, the fastener is designed as a flexible element, which allows it to be bent and / or be elastic in the longitudinal direction of the suspension frame; the thermal expansion of the magnet unit can be compensated by the fastener bending in the longitudinal direction, thus the fastener is bent in the longitudinal direction.

[0022] Additionally or alternatively, it is advantageous if the fastener has tensile strength in its longitudinal extension, thereby allowing the fastener to transmit the pulling or lifting force used to lift the suspended vehicle.

[0023] Advantageously, the frame element has at least one expansion recess; during thermal expansion, the magnet unit, especially the fixing element, can move into the expansion recess.

[0024] The present invention also provides a chassis for a levitation vehicle for a maglev train, having a plurality of levitation frames interconnected longitudinally in the chassis, wherein the chassis is disposed below the carriage of the levitation vehicle.

[0025] According to the present invention, at least one suspension frame is designed based on at least one of the features described above and / or below.

[0026] Furthermore, the present invention also proposes a levitation vehicle for a maglev train with a chassis, which is 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

[0072] Figure 1 A side view of the levitation vehicle 2 is shown. This levitation vehicle 2 is used in maglev trains, where it can be levitated on a track (not shown) by magnetic force and / or driven by magnetic force. The levitation vehicle 2 includes a chassis 3 and a carriage 4 mounted thereon for passengers and operators; the chassis 3 is, of course, located below the carriage 4. It is clear from the figure that the vertical direction Z is the height direction, or the direction transverse to the longitudinal direction X of the levitation vehicle 2.

[0073] In this embodiment, the chassis 3 includes five suspension frames 1a-1e on each longitudinal side, and the chassis 3 therefore includes a total of ten suspension frames 1; with the help of these suspension frames 1, the suspended vehicle 2 can be suspended on the track and / or driven.

[0074] Figure 2 A perspective schematic diagram of a magnet unit 5 for lifting, carrying, guiding, and / or driving the levitated vehicle 2 is shown. The levitated vehicle 2 can be lifted off the track by magnetic force via the magnet unit 5; additionally or alternatively, the levitated vehicle 2 can also be driven by the magnet unit 5; the magnet unit 5 is, for example, part of a short-stator asynchronous linear motor. Since the levitated vehicle 2 can be lifted off the track by magnetic force and can also be driven by magnetic force, it does not contact the track, thus enabling it to be driven with exceptionally low running resistance, essentially only experiencing air resistance and no rolling resistance.

[0075] According to this embodiment, the magnet unit 5 includes a magnetic core 7 and at least one coil unit 8, 9, two of which are shown in the figure. The coil units 8, 9 have windings to convert current into a magnetic field, and the magnetic core 7 enhances the magnetic field. The magnetic core 7 and the at least one coil unit 8, 9 together form the main part 6 of the linear motor, another part of which is disposed in a track. The track may include, for example, a reactive track that interacts with the magnetic field of the main part 6 to lift and / or drive the levitated vehicle 2.

[0076] According to this embodiment, the magnet unit 5 further includes a support unit 10, on which the main part 6 is disposed; the support unit 10 may be designed as a plate to support the main part 6.

[0077] The main part 6, along with its magnetic core 7, coil units 8 and 9, and the supporting unit 10, all extend in the longitudinal direction X, as shown in the figure. During the operation of the maglev train, i.e., when the coil units 8 and 9 are energized, the magnetic unit 5, especially the main part 6, heats up and expands, with the thermal expansion mainly occurring in the longitudinal direction X.

[0078] The magnet unit 5 also has at least one fixing member 11-14, by which the magnet unit 5 can be mounted on a frame element of the suspension frame 1. Four fixing members 11-14 are shown in the figure. The first fixing member 11 is disposed at the end 15 of the first magnet unit, and the second fixing member 12 is disposed at the end 16 of the second magnet unit opposite to the end 15 of the first magnet unit in the longitudinal direction X.

[0079] At least one additional fastener 13, 14, Figure 2 Two additional fasteners are shown, disposed in the region of the center 17 of the magnet unit, that is, between the ends 15 and 16 of the first and second magnet units; according to this embodiment, the third and fourth fasteners 13 and 14 are arranged to be rotated 90 degrees relative to the first and second fasteners 11 and 12; in addition, the third and fourth fasteners 13 and 14 are arranged to be spaced apart from each other in the transverse Y direction.

[0080] Furthermore, the at least one fastener 11-14 extends away from the support unit 10 in a vertical direction Z, which is derived from the intended use of the suspension frame 1 in the suspension vehicle 2; in addition, the at least one fastener 11-14 extends vertically away from the support unit 10.

[0081] In addition, at least one fastener 11-14, particularly in its end region away from the support unit 10, has at least one pin as a connector 18, wherein each fastener 11-14 has two pins, which may be tapered.

[0082] The pin serving as connector 18 can be inserted into the groove 25 of frame element 20 to, for example, align magnet unit 5 onto frame element 20 (see...). Figure 3 and 4 ).

[0083] Furthermore, the at least one fastener 11-14 has at least one hole 19 through which a screw can pass to connect the fastener 11-14 to the frame element 20, although other connection methods may also be used. The hole 19 is also arranged to align with a connector 18 designed as a pin, whereby the connector 18 also has a channel coaxial with the hole 19. As an example, a screw used to connect the fastener 11-14 to the frame element 20 can thus be guided and pass through the hole 19 and the channel of the connector 18.

[0084] Figure 3 A perspective view of the frame element 20 of the suspended frame 1 is shown. (As shown) Figure 2 The magnet unit 5 shown can be disposed on the frame element 20.

[0085] The frame element 20 has a first side portion 21 and a second side portion 22 spaced apart from it in the longitudinal direction X; furthermore, the frame element 20 has a longitudinal portion 23 on one longitudinal side; in this embodiment, the longitudinal side of the frame element 20 opposite to the longitudinal portion 23 in the transverse direction Y is in an open state because Figure 2 The magnet unit 5 has third and fourth fasteners 13 and 14, so it is advantageous if the frame element 20 has a second longitudinal portion 23 (not shown). When the magnet unit 5 is connected to the frame element 20, the frame element 20 is arranged around the entire periphery of the magnet unit 5, where the magnet unit 5 can be connected to the frame element 20 on each of the four sides.

[0086] In addition, the frame element 20 also has a bottom 24.

[0087] Furthermore, grooves 25 are provided in the first side portion 21, the longitudinal portion 23, and the second side portion 22; if the frame element 20 has a second longitudinal portion 23, the grooves 25 may also be provided therein, for example, symmetrically provided in the longitudinal portion 23 shown here. Since it is shown in perspective, these grooves 25 are not visible in the second side portion 22.

[0088] Figure 2 The fasteners 11-14 of the magnet unit 5, for example, designed as pins, can be inserted into the groove 25, thereby aligning the magnet unit 5 with the frame element 20.

[0089] In addition, the groove 25 may have threaded holes not shown in the figure, through which the fasteners 11-14 can be screwed.

[0090] Figure 4 A side sectional view of the suspended frame 1 is shown, wherein the suspended frame includes frame element 20 (see...). Figure 3 ) and the magnet unit 5 disposed thereon (see Figure 2 ).

[0091] Furthermore, for the sake of simplicity, the features and their functions already described in the preceding figures will not be explained again. Additionally, the same reference numerals are used for the same features, or features that appear similar, compared to the preceding and / or following figures. For the sake of simplicity, features may also be described only in subsequent figures, for example.

[0092] The magnet unit 5 is connected to the frame element 20 via at least one fixed bearing 26 and at least one movable bearing 27, 28; the magnet unit 5 and the frame element 20 are rigidly connected to each other in the longitudinal direction X of the suspension frame 1 on the fixed bearing 26; therefore, the magnet unit 5 is immovable relative to the frame element 20 in the longitudinal direction X on the fixed bearing 26, and thus the fixed bearing 26 is a fixed bearing 26 in the longitudinal direction X.

[0093] In addition, the suspension frame 1 has at least one movable bearing 27, 28, which is spaced apart from at least one fixed bearing 26 in the longitudinal direction X; the movable bearing 27, 28 also connects the magnet unit 5 and the frame element 20 to each other so that they can move along the longitudinal direction X of the suspension frame 1, so the movable bearing 27, 28 is a movable bearing in the longitudinal direction X.

[0094] When thermal expansion WA occurs, the magnet unit 5 can move longitudinally X relative to the frame element 20 via the movable bearings 27 and 28, thereby avoiding stress between the magnet unit 5 and the frame element 20; thermal expansion WA is marked by two outward arrows in the figure; with the help of these movable bearings 27 and 28, the magnet unit 5 can also move relative to the frame element 20 in the case of contraction, the direction of thermal contraction being opposite to the direction of thermal expansion WA, thus also avoiding stress generation.

[0095] The first movable bearing 27 is located in the region of the first suspension frame end 29, while the second movable bearing 28 is located in the region of the second suspension frame end 30, and the fixed bearing 26 is located in the region of the suspension frame center 31. Therefore, the fixed bearing 26 is located between the two movable bearings 27 and 28.

[0096] Furthermore, for example, a pin-shaped connector 18 is provided in a corresponding recess 25, both of which are tapered, allowing for mutual alignment. The three corresponding fasteners 11-13 shown here are secured to the first side 21, the second side 22, and the longitudinal portion 23 by schematically shown threaded connections 32, whereby the fasteners 11-13 are fully connected to the frame element in the region of the threaded connections 32. Alternatively, instead of threaded connections, a longitudinal X-oriented movable connection can be formed between the fasteners 11-14 and the frame element 20. For example, the frame element 20 may have an axis oriented longitudinally X in movable bearings 27, 28, on which the fasteners 11, 12 can move longitudinally X to compensate for thermal expansion WA. Through this axis, the fasteners 11, 12 are fixed in the movable bearings 27, 28 in the vertical direction Z and the transverse direction Y, or securely connected to the frame element 20.

[0097] According to this embodiment, the fasteners 11-14 are designed as flexible beams, at least in the movable bearings 27 and 28, which can be bent in the longitudinal direction X. Therefore, the bending behavior of the fasteners 11-14 in the movable bearings 27 and 28 along the longitudinal direction X can be used to compensate for thermal expansion WA. The fasteners bend outward when the magnet unit 5 expands and bend inward when the magnet unit 5 contracts, thereby compensating for thermal expansion WA even though the fasteners 11-14 are securely connected to the frame element 20 by the screws 32 shown herein.

[0098] According to this embodiment, the frame element 20 has a first expansion recess 33 belonging to the first movable bearing 27 and a second expansion recess 34 belonging to the second movable bearing 28. When the magnet unit 5 expands due to thermal expansion WA, the corresponding fasteners 11, 12 and / or the magnet unit 5 can be bent into the two expansion recesses 33, 34.

[0099] The above figures and the described embodiments are not intended to limit the scope of the invention. All equivalent changes and modifications made in accordance with the claims of this 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 this invention.
