Description

TECHNICAL FIELD

[0001] The invention relates to a chassis for a track-bound levitation vehicle of a maglev train, comprising two vertical rows of a plurality of levitation frames, which are spaced apart from each other in a transverse direction of the chassis and extend in a longitudinal direction of the chassis, at least two crossbars, which are spaced apart in the longitudinal direction and extend in the transverse direction, the crossbars being arranged between and connected to the levitation frames spaced apart in the transverse direction, at least one longitudinal bar extending in the longitudinal direction, which is connected to the crossbars, and at least one receiving device for receiving a car of the levitation vehicle. BACKGROUND

[0002] CN 106347168 A discloses a chassis for a track-bound levitation vehicle of a maglev train. The chassis comprises crossbars and longitudinal bars, wherein a plurality of layers or planes of the longitudinal bars are arranged overlapping.

[0003] SUMMARY

[0004] Therefore, it is an object of the present invention to improve the state of the art.

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

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

[0007] The chassis comprises two vertical rows of a plurality of levitation frames, which are spaced apart from each other in a transverse direction of the chassis and extend in a longitudinal direction of the chassis. Thus, the two vertical rows of a plurality of levitation frames correspond to a track having two rails.

[0008] Further, the chassis comprises at least two crossbars, which are spaced apart in the longitudinal direction and extend in the transverse direction, the crossbars connecting the two vertical rows of a plurality of levitation frames.

[0009] Further, the chassis comprises at least one longitudinal bar extending in the longitudinal direction, which is connected to the crossbars.

[0010] Further, the chassis comprises at least one receiving device for receiving a car of the levitation vehicle.

[0011] Further, the chassis preferably comprises at least one suspension system for elastically mounting the car with respect to the chassis.

[0012] In particular, the crossbars and / or the longitudinal bars can be load-bearing components for the car.

[0013] According to the invention, two longitudinal bars spaced apart in the transverse direction are arranged between two crossbars spaced apart in the longitudinal direction and the longitudinal bars are connected to the two crossbars, so that the car can be more stably supported by the crossbars and the longitudinal bars.

[0014] Advantageously, only one crossbar is positioned between and connected to the two suspension frames that are laterally spaced, allowing the suspension frames to pivot relative to the crossbar when the chassis turns.

[0015] Alternatively or additionally, it is advantageous that, of the two crossbars between which the two longitudinal bars are disposed, the first crossbar is disposed between and connected to two laterally spaced suspended frames, and the second crossbar is disposed between and connected to two other laterally spaced suspended frames. Specifically, the first and second crossbars may be disposed between two pairs of suspended frames that are directly adjacent to each other longitudinally. Thus, the first and second crossbars are disposed between four suspended frames.

[0016] Advantageously, the longitudinal struts are arranged parallel to the suspension frame. Alternatively or additionally, the longitudinal struts are spaced apart from the suspension frame in the transverse direction.

[0017] Advantageously, the first suspension system elastically supports the crossbars relative to the suspension frame. Alternatively, it is also advantageous for the second suspension system to elastically mount the longitudinal bars relative to the crossbars. With the first and / or second suspension systems, the vehicle body can be elastically mounted relative to the chassis.

[0018] Advantageously, the first suspension system has a first spring assembly. Alternatively or additionally, the second suspension system may have a second spring assembly.

[0019] Advantageously, the first spring assembly includes a tapered and / or layered spring. Alternatively or additionally, the second spring assembly may also include a tapered and / or layered spring.

[0020] Advantageously, the crossbars and / or longitudinal bars have elasticity and / or resilience, particularly in the vertical, longitudinal, and / or transverse directions. Therefore, the crossbars and / or longitudinal bars also increase the elasticity of the carriage. Preferably, the crossbars and / or longitudinal bars have a spring constant of less than or equal to 10,000 N / mm, particularly in the vertical, longitudinal, and / or transverse directions.

[0021] Advantageously, the crossbar has two ends, with a first end connected to a suspension frame and a second end of the crossbar opposite to the first end connected to a suspension frame spaced laterally.

[0022] Advantageously, the longitudinal bar has two ends, a first end of which is connected to a crossbar, and a second end of which, opposite to the first end, is connected to crossbars spaced apart longitudinally.

[0023] Advantageously, the suspension frame has a recess, and the end of the crossbar is disposed in the recess together with the corresponding suspension frame. This allows the chassis to be designed in a more space-saving manner.

[0024] Advantageously, the longitudinal bar is rotatably connected to the transverse bar.

[0025] Advantageously, the receiving device is located in the middle area of ​​the longitudinal bar, especially in its very center.

[0026] Advantageously, the receiving device includes a support member, or the receiving device can support the support member, and the carriage can be mounted on the support member, particularly directly on the support member.

[0027] Advantageously, the suspension frames are connected to each other longitudinally by longitudinal connectors and / or laterally by transverse connectors. In this way, the crossbars and longitudinal bars only need to transfer the weight of the car body to the suspension frames. Therefore, the crossbars and longitudinal bars contribute little or nothing to the connection between the individual suspension frames.

[0028] Further advantages of the invention are described in the following embodiments. Attached Figure Description

[0059] Figure 1 A top view schematic diagram of the chassis 1 used for the levitation vehicle 7 is shown. This chassis 1 is specifically designed for maglev trains, in which the levitation vehicle 7 is suspended on the track without contact. The levitation vehicle 7 is maintained in a levitation state by magnetic force.

[0060] The chassis 1 includes a plurality of suspended frames 2a-2j arranged adjacent to each other in the longitudinal (X) and transverse (Y) directions. Specifically, the chassis 1 includes two vertical rows 21 and 22 spaced apart in the transverse (Y) direction, each row consisting of a plurality of suspended frames 2. Suspended frames 2a, 2c, 2e, 2g, and 2i form the first vertical row 21, and suspended frames 2b, 2d, 2f, 2h, and 2j form the second vertical row 22. Furthermore, when the suspended vehicle 7 moves, the longitudinal (X) direction is parallel to the direction of travel. In this embodiment, the chassis 1 has ten suspended frames 2a-2j, with five suspended frames 2a-2j arranged on each side of the chassis 1. In this case, two suspended frames 2a-2j spaced apart in the transverse (Y) direction can form a pair of suspended frames.

[0061] The suspension frames 2a-2j may contain magnets so as to generate the magnetic force required for the hovercraft 7 to levitate.

[0062] Furthermore, according to this embodiment, the suspended frames 2a-2j are connected to each other in the longitudinal direction X by longitudinal connectors 5a-5h. The longitudinal connectors 5a-5h can be hinged, allowing the suspended frames 2a-2j to adapt to curves when bending. In this case, the longitudinal connectors 5a-5h are respectively connected to two adjacent suspended frames 2a-2j in the longitudinal direction X, thereby connecting the suspended frames 2a-2j to form two vertical rows 21, 22.

[0063] Furthermore, according to this embodiment, two vertical rows 21 and 22, each composed of a suspension frame 2a-2j, are connected to each other in the transverse Y direction by transverse connectors 6a-6d. Four transverse connectors 6a-6d are exemplarily shown here, but the chassis 1 may have more than four. The transverse connectors 6a-6d may be hinged, allowing the suspension frames 2a-2j to pivot relative to the transverse connectors 6a-6d to adapt to curves during cornering. As shown in this embodiment, the transverse connector 6c between the two suspension frames 2e and 2f is rigidly connected to the two suspension frames. Therefore, in this embodiment, even during cornering, the two suspension frames 2e and 2f remain parallel to each other and / or do not pivot relative to the transverse connector 6c.

[0064] The chassis 1 further includes at least two crossbars 3a-3d. In this embodiment, the chassis 1 has four crossbars 3a-3d. At least two crossbars 3a-3d are spaced apart from each other in the longitudinal direction X and extend in the transverse direction Y. The crossbars 3a-3d are further connected to two vertical rows 21, 22 composed of suspension frames 2a-2j. Specifically, each crossbar 3a-3d is connected to two suspension frames 2a-2j. For example, the first crossbar 3a is connected to two suspension frames 2a, 2b. Each crossbar 3a-3d is connected to two suspension frames 2a-2j spaced apart in the transverse direction Y.

[0065] Furthermore, the chassis 1 includes at least two longitudinal bars 4a-4d, which are disposed between and connected to at least two transverse bars 3a-3d. The two longitudinal bars 4a-4d are also spaced apart from each other in the transverse Y direction. The longitudinal bars 4a-4d also extend in the longitudinal X direction.

[0066] The crossbars 3a-3d and the longitudinal bars 4a-4d also form at least one spring system 9a, 9b.

[0067] According to this embodiment, chassis 1 has two spring systems 9a and 9b. Two crossbars 3a and 3b and two longitudinal bars 4a and 4b form the first spring system 9a. Two crossbars 3c and 3d and two longitudinal bars 4c and 4d form the second spring system 9b.

[0068] According to this implementation scheme, each spring system 9 includes two crossbars 3 and two longitudinal bars 4.

[0069] According to this embodiment, crossbar 3a is positioned between two suspended frames 2a and 2b, and crossbar 3b is positioned between two suspended frames 2c and 2d. Therefore, only one crossbar 3a-3d is positioned between two suspended frames 2a-2j that are spaced apart from each other along the transverse Y direction.

[0070] Therefore, the spring systems 9a and 9b extend between the four suspension frames 2a-2j.

[0071] The two spring systems 9a, 9b or the chassis 1 also have at least one suspension system 10, 11 for elastically mounting the crossbars 3a-3d and / or longitudinal bars 4a-4d. Furthermore, the spring systems 9a, 9b and / or longitudinal bars 4a-4d include a receiving device 18 for supporting the carriage 8. The carriage 8 can be elastically mounted relative to the suspension frames 2a-2j via the spring systems 9a, 9b or at least one suspension system 10, 11. At least one suspension system 10, 11 and the receiving device 18 are shown in at least one of the following figures.

[0072] For the sake of brevity, features already described in at least one of the preceding figures will not be further explained. Furthermore, descriptions of features may also be given in subsequent figures. Additionally, for the sake of brevity, the same reference numerals are used for the same features. Furthermore, for the sake of simplicity, not all features are shown in the following figures; however, features shown in one or more of the foregoing figures may also be present in one or more subsequent figures. Furthermore, for clarity, features may also be shown in one or more subsequent figures. Nevertheless, features shown in one or more subsequent figures may already exist in the preceding figures.

[0073] Figure 2 It shows Figure 1 Sectional view along section line AA Figure 2 It shows passing through the suspended frames 2i, 2j, and passing through Figure 1 A sectional view of the horizontal bar 3d and the two vertical bars 4c and 4d.

[0074] Furthermore, the chassis 1 or the second spring system 9b shown in the above cross-sectional view includes at least one suspension system 10, 11. The features described in the second spring system 9b can, of course, also be present in the first spring system 9a.

[0075] According to this embodiment, the first suspension system 10 is disposed between the crossbar 3d and the two suspension frames 2i, 2j, so as to elastically mount the crossbar 3d relative to the corresponding suspension frames 2i, 2j. Alternatively or additionally, other crossbars 3 may also have the first suspension system 10.

[0076] According to this embodiment, the first suspension system 10 includes at least one first spring assembly 19a, 19b. The first spring assemblies 19a, 19b are respectively disposed between the crossbar 3d shown herein and one of the two suspension frames 2i, 2j. The first spring assembly 19a is disposed between a first end 12 of the crossbar 3d and the corresponding suspension frame 2i. The first end 12 of the crossbar 3d is also referred to as the first crossbar end 12. The other first spring assembly 19b is disposed between a second end 13 of the crossbar 3d and the corresponding suspension frame 2j. The second end 13 of the crossbar 3d is also referred to as the second crossbar end 13. By means of the first suspension system 10, the crossbar 3d is elastically mounted relative to the corresponding suspension frames 2i, 2j.

[0077] Alternatively or additionally, according to this embodiment, the chassis 1 or the second spring system 9b has a second suspension system 11. The second suspension system 11 elastically supports the two longitudinal bars 4c, 4d relative to the crossbar 3d. The second suspension system 11 may also be disposed between other longitudinal bars 4 and corresponding crossbars 3.

[0078] The second suspension system 11 includes at least one second spring assembly 20a, 20b. According to this embodiment, the second suspension system 11 includes two spring assemblies 20a, 20b, wherein the second spring assemblies 20a, 20b are respectively disposed between corresponding longitudinal bars 4c, 4d and transverse bar 3d. In this embodiment, at least one spring assembly 20a, 20b is further designed as a layered spring. The second spring assembly 20a, designed as a layered spring, is disposed between the longitudinal bar 4c and the transverse bar 3d, and the second spring assembly 20b, designed as a layered spring, is disposed between the longitudinal bar 4d and the transverse bar 3d. By means of the second suspension system 11, the two longitudinal bars 4c, 4d are thus elastically mounted relative to the transverse bar 3d.

[0079] Furthermore, support member 14 can be used to couple the carriage 8, shown only partially here, to chassis 1. Support member 14 is thus mounted on longitudinal bars 4c, 4d shown in the sectional view. Support member 14 can be attached to receiving device 18 (not shown). Receiving device 18 can also be referred to as a fixing device. Alternatively or additionally, support member 14 can also be receiving device 18. Longitudinal bar 4 can have receiving device 18.

[0080] With the aid of at least one suspension system 10, 11, the carriage 8 can be flexibly mounted relative to the suspension frames 2a-2j. Therefore, the carriage 8 has a shock-absorbing effect relative to the suspension frames 2a-2j.

[0081] According to this embodiment, both suspended frames 2i and 2j shown here have recesses 15a and 15b. A crossbar 3d can be disposed in the recesses 15a and 15b, such that the crossbar 3d is at least partially disposed within the suspended frames 2i and 2j.

[0082] For the sake of brevity, features already described in at least one of the preceding figures will not be further explained. Furthermore, descriptions of features may only be given in subsequent figures. Also, for the sake of brevity, the same reference numerals are used for the same features. Furthermore, to keep the figures simple, not all features are shown in the following figures. However, features shown in one or more of the foregoing figures may also be present in one or more subsequent figures. Furthermore, for clarity, features may also be shown in one or more subsequent figures. Nevertheless, features shown in one or more subsequent figures may already be present in the preceding figures.

[0083] Figure 3 It shows according to Figure 1 The cross-sectional view of chassis 1 along section line BB is shown here. The cross-sectional view shown here passes through the first spring system 9a. The features of the first spring system 9a can of course also be applied to the second spring system 9b.

[0084] The viewing direction here is along the transverse Y direction. Two suspended frames 2a and 2c connected to each other by a longitudinal connector 5a are shown here. Furthermore, a transverse connector 6a is shown in the sectional view, which connects the two suspended frames 2a and 2b to each other in the transverse Y direction (see [link]). Figure 1 In addition, the vertical direction Z is shown here.

[0085] As shown in the longitudinal bar 4b here, the longitudinal bar 4b has a first end 16 and a second end 17. The first end 16 of the longitudinal bar 4b is therefore also referred to as the first longitudinal bar end 16. The second end 17 of the longitudinal bar 4b is therefore also referred to as the second longitudinal bar end 17.

[0086] The first end 16 of the longitudinal bar 4b is connected to the first crossbar 3a shown here, and the second end 17 of the longitudinal bar 4b is connected to the second crossbar 3b shown here.

[0087] The second suspension system 11 is also disposed between the longitudinal bar 4b shown here and the two crossbars 3a, 3b shown here. Furthermore, a second spring assembly 20c, designed as a layered spring, is disposed between the longitudinal bar 4b (particularly the first end 16 of the longitudinal bar 4b) and the first crossbar 3a. A second spring assembly 20d, also in the form of a layered spring, is disposed between the longitudinal bar 4b (particularly the second end 17 of the longitudinal bar 4b) and the second crossbar 3b.

[0088] Furthermore, the first suspension system 10 is disposed between the two crossbars 3a and 3b shown here and the two suspension frames 2a and 2c. A first spring assembly 19c in the form of a conical spring is disposed between the first crossbar 3a and the suspension frame 2a, and a first spring assembly 19d in the form of a conical spring is disposed between the second crossbar 3b and the suspension frame 2c.

[0089] The longitudinal strut 4b also has a receiving device 18 on which the carriage 8 (not shown) can be received. The receiving device 18 can be designed as a swing bracket, on which the support member 14 carrying the carriage 8 is received. The receiving device 18 may also include the support member 14. The receiving device 18, particularly the swing bracket, can be configured such that the support member 14 can rotate or pivot about the longitudinal direction X, thereby allowing the carriage 8 to tilt or pivot relative to the chassis 1 about the longitudinal direction X.

[0090] The spring system 9a shown here includes first and second suspension systems 10, 11, wherein the carriage 8 is elastically mounted relative to the chassis 1 via the spring system 9a. In this embodiment, the spring system 9a or the first suspension system 10 shown here includes a total of four first spring assemblies 19, for example, the first spring assembly 19 may be designed as a conical spring.

[0091] In addition, the second suspension system 11 also includes four second spring assemblies 20, which can be designed as layered springs.

[0092] In addition, the first suspension system 10 may include a layered spring and / or the second suspension system 11 may include a conical spring.

[0093] Alternatively or additionally, the longitudinal bar 4 can also be designed to be elastic. The longitudinal bar 4 can be elastic along the vertical, longitudinal, and / or transverse Z, X, Y directions. Therefore, the carriage 8, not shown here, can be elastically mounted relative to the chassis 1. Specifically, the elasticity of the longitudinal bar 4 along the vertical Z direction is configured such that the longitudinal bar 4 can bend between the corresponding crossbars 3 and bend back again. The elasticity of the longitudinal bar 4 can be achieved, for example, through the appropriate selection of materials. The longitudinal bar 4 is thus similar to a leaf spring.

[0094] Figure 4 A schematic side view of the levitation car 7 of the maglev train, which has a chassis 1 and a carriage 8, is shown. Here, five suspended frames 2b, 2d, 2f, 2h, and 2j shown in the side view are shown, each connected to the other by longitudinal connectors 5b, 5d, 5f, 5, and 5h.

[0095] In addition, two support members 14a and 14b for supporting the carriage 8 are shown. The first support member 14a belongs to the first spring system 9a, and the second support member 14b belongs to the second spring system 9b, thereby suspending the carriage 8 relative to the chassis 1.

[0096] This invention is not limited to the embodiments shown and described above. As with combinations of features, variations are possible within the scope of the claims, even though they are shown and described in different embodiments.
