Abstract
Description
[0001] Chassis for a track-bound hover vehicle of a magnetic levitation train
[0002] The present invention relates to a chassis for a track-bound levitation vehicle of a magnetic levitation train, with two rows of several levitation frames spaced apart from one another in a transverse direction of the chassis and extending in a longitudinal direction of the chassis, with at least one transverse cross member extending in the transverse direction and with at least one longitudinal cross member extending in the longitudinal direction, which is connected to the at least one transverse cross member.
[0003] EP 0 059 443 A2 discloses a chassis for a magnetic levitation train, which comprises spring elements that cushion a vehicle cabin. However, the disadvantage is that such suspension is inadequate.
[0004] The object of the present invention is therefore to improve the suspension of the vehicle cabin in magnetic levitation trains.
[0005] The problem is solved by a chassis and a hover vehicle with the features of the independent patent claims.
[0006] A chassis is proposed for a track-bound levitation vehicle of a magnetic levitation train. In a magnetic levitation train, movement occurs without contact with a track. The levitation vehicle is lifted and propelled by magnetic forces.
[0007] The landing gear comprises two rows of multiple hover frames spaced apart in a transverse direction of the landing gear and extending in a longitudinal direction of the landing gear. The hover frames can include magnets that lift and drive the landing gear and thus the hover vehicle.
[0008] Furthermore, the chassis comprises at least one transverse cross member extending in the transverse direction and at least one longitudinal cross member extending in the longitudinal direction, which is connected to the at least one transverse cross member.
[0009] In addition, at least one transverse spring is arranged between the at least one longitudinal cross member and the at least one transverse cross member, so that the longitudinal and transverse cross members are sprung relative to each other in the transverse direction. This also allows vibrations acting in the transverse direction to be cushioned, dampened, and / or absorbed.
[0010] Additionally or alternatively, the chassis, in particular the crossbeam, has a transverse stop for the at least one longitudinal beam, so that movement of the longitudinal beam in the transverse direction is limited by the transverse stop. The longitudinal beam can abut or does abut against the transverse stop in the transverse direction, so that the longitudinal beam is limited or guided in its movement in the transverse direction.
[0011] It is advantageous if the transverse suspension is arranged between the transverse stop and the longitudinal cross member. The transverse stop can be located on the cross member. This allows the transverse suspension and / or the longitudinal cross member to be supported on the transverse stop.
[0012] It is advantageous if the at least one transverse stop is arranged detachably or permanently on the crossbeam. This allows the transverse stop to be arranged and / or replaced as desired on the crossbeam. It is advantageous if the at least one transverse stop and the crossbeam are formed as a single piece. It is advantageous if a transverse spring is arranged on an inner longitudinal side and / or on an outer longitudinal side of the longitudinal beam. This allows the longitudinal beam to be spring-loaded on both sides, for example.
[0013] It is advantageous if the at least one longitudinal cross member is arranged between two cross members, wherein the longitudinal cross member is connected to both cross members.
[0014] It is advantageous if two longitudinal beams are arranged between two cross beams spaced apart from each other in the longitudinal direction.
[0015] It is advantageous if the at least one transverse spring is arranged in the region of a first and / or a second longitudinal cross member end. This allows both ends of the longitudinal cross member to be spring-loaded in the transverse direction.
[0016] It is also advantageous if a crossbeam is arranged between two longitudinal crossbeams spaced apart in the transverse direction, connecting a vehicle cabin to the chassis. The crossbeam is connected at its ends to the two longitudinal crossbeams. The vehicle cabin thus rests on the crossbeam. For this purpose, the crossbeam can have support means to which the vehicle cabin is coupled to the crossbeam, for example, by means of supports or struts.
[0017] It is advantageous if the transverse suspension on the inner longitudinal side and / or the transverse suspension on the outer longitudinal side of the longitudinal cross member is arranged with a fastening element on the longitudinal cross member, in particular one which passes through the longitudinal cross member in the transverse direction.
[0018] It is advantageous if the at least one transverse spring is bolted to the longitudinal cross member, with the transverse spring preferably having a through-hole through which it is bolted. It is advantageous if the transverse spring is a spring block, particularly made of rubber. This allows for reliable suspension.
[0019] Furthermore, a hover vehicle with a chassis is proposed, wherein the chassis has at least one feature of the preceding and / or following description.
[0020] Further advantages of the invention are described in the following exemplary embodiments. They show:
[0021] Figure 1 is a plan view of a schematic representation of a landing gear for a hover vehicle,
[0022] Figure 2 is a plan view of a section of the chassis with transverse suspension,
[0023] Figure 3 shows a cross section through the chassis and
[0024] Figure 4 is a schematic view of the hover vehicle with landing gear.
[0025] Figure 1 shows a top view of a schematic representation of a chassis 1 for a levitating vehicle 9. The chassis 1 is particularly suitable for a magnetic levitation train, in which the levitating vehicle 9 hovers contactlessly above a track. The levitating vehicle 9 is held in suspension by magnetic force and / or propelled by magnetic forces.
[0026] The chassis 1 comprises a plurality of suspended frames 2a - 2j, which are arranged at a distance from one another in the longitudinal direction X and in the transverse direction Y. The chassis 1 comprises two rows 7, 8 of a plurality of suspended frames 2, which are spaced apart from one another in the transverse direction Y. The suspended frames 2a, 2c, 2e, 2g, 2i form the first row 7 and the suspended frames 2b, 2d, 2f, 2h, 2j form the second row 8. The longitudinal direction X is also parallel to a direction of travel when the hovercraft 9 is moving. In the present exemplary embodiment, the chassis 1 has ten suspended frames 2a - 2j, with five suspended frames 2a - 2j being arranged on each side of the chassis 1. Two suspended frames 2a - 2j spaced apart from one another in the transverse direction Y can form a pair of suspended frames.
[0027] The hover frames 2a - 2j can comprise magnets in order to be able to generate the magnetic force necessary for hovering and / or propelling the hover vehicle 9.
[0028] Furthermore, according to the present embodiment, the floating frames 2a-2j are connected to one another in the longitudinal direction X by means of longitudinal connections 5a-5h. The longitudinal connections 5a-5h can be articulated, so that the floating frames 2a-2j can adapt to the curve when cornering. The longitudinal connections 5a-5h each connect two floating frames 2a-2j adjacent to one another in the longitudinal direction X, so that the floating frames 2a-2j are connected to form the two rows 7, 8.
[0029] Additionally, according to the present embodiment, the two rows 7, 8 of suspended frames 2a-2j are connected to one another in the transverse direction Y by means of cross connections 6a-6d. Four cross connections 6a-6d are shown here as an example, although the chassis 1 may also have more than four cross connections 6a-6d. The cross connections 6a-6d may have articulated connections so that the suspended frames 2a-2j can also pivot relative to the cross connections 6a-6d in order to adapt to the curve when cornering. As shown in this embodiment, the cross connections 6b and 6c between the two suspended frames 2e, 2f are rigidly connected to them. In this embodiment, the two suspended frames 2e, 2f thus remain parallel to one another even when cornering and / or do not pivot relative to the cross connections 6b and 6c.
[0030] The chassis 1 further comprises at least one crossbeam 3a-3d. In this exemplary embodiment, the chassis 1 comprises four crossbeams 3a-3d. The crossbeams 3a-3d shown here are spaced apart from one another in the longitudinal direction X and extend in the transverse direction Y. The crossbeams 3a-3d are further connected to the two rows 7, 8 of floating frames 2a-2j. In particular, each crossbeam 3a-3d is connected to two floating frames 2a-2j. For example, the first crossbeam 3a is connected to the two floating frames 2a, 2b. The crossbeams 3a-3d are each connected to the two floating frames 2a-2j spaced apart from one another in the transverse direction Y.
[0031] The chassis 1 further comprises at least one longitudinal cross member 4a-4d, which is arranged on and connected to the at least one transverse cross member 3a-3d. Four longitudinal cross members 4a-4d are shown here, with at least two longitudinal cross members 4a-4d being spaced apart from one another in the transverse direction Y. The longitudinal cross members 4a-4d also extend in the longitudinal direction X.
[0032] According to the present exemplary embodiment, two longitudinal cross members 4a, 4b spaced apart in the transverse direction Y are arranged between the two cross members 3a, 3b spaced apart in the longitudinal direction X. The two cross members 3a, 3b and the two longitudinal cross members 4a, 4b form a first cross member system 10a. Furthermore, the chassis 1 comprises a second cross member system 10b, which comprises the two cross members 3c, 3d spaced apart in the longitudinal direction X, as well as the two longitudinal cross members 4c, 4d arranged on the cross members 3c, 3d and spaced apart in the transverse direction Y. The two cross member systems 10a, 10b shown here each comprise two cross members 3 and two longitudinal cross members 4. In the cross member systems 10, the cross members 3 and the longitudinal cross members 4 are arranged in a parallelogram. The two truss systems 10 are essentially identical to each other and spaced apart from each other in the longitudinal direction X.
[0033] Features that have already been described in at least one previous figure cannot be explained again for the sake of simplicity. Furthermore, features can also be described in this or in at least one of the subsequent figures. Furthermore, for the sake of simplicity, the same reference symbols are used for the same features. Moreover, for the sake of clarity, not all features can be shown and / or provided with a reference symbol in the following figures. However, features shown in one or more of the previous figures can also be present in this or in one or more of the subsequent figures. Furthermore, for the sake of clarity, features can also be shown and / or provided with a reference symbol in this or in one or more of the subsequent figures.Nevertheless, features which are only shown in one or more of the subsequent figures may already be present in this or a previous figure.
[0034] Figure 2 shows a top view of a section of the landing gear 1, with only four floating frames 2a-2d shown. For example, the four uppermost floating frames 2a-2d of Figure 1 are shown.
[0035] The view shown here shows the first truss system 10a with the two transverse trusses 3a, 3b and the two longitudinal trusses 4a, 4b. The second truss system 10b, not shown here, is advantageously designed identically to the first truss system 10a shown here. For the sake of simplicity, only the first truss system 10a is shown.
[0036] Furthermore, at least one transverse spring 11 is arranged between the at least one longitudinal cross member 4 and the at least one transverse cross member 3, so that the longitudinal cross member 4 and the transverse cross member 3 are sprung relative to one another in the transverse direction Y. As a result, vibrations acting in the transverse direction Y can be cushioned, dampened, and / or absorbed.
[0037] In the present embodiment, four transverse suspensions 11a-11d are shown. Two transverse beams 3a, 3b and two longitudinal beams 4a, 4b are shown, with four contact points arranged between the two transverse beams 3a, 3b and the two longitudinal beams 4a, 4b. Each of the two longitudinal beams 4a, 4b is connected by its two longitudinal beam ends 15, 16 to a respective transverse beam 3a, 3b. Furthermore, each of the two longitudinal beams 4a, 4b is arranged on each of the two transverse beams 3a, 3b. This results in four transverse suspensions 11a-11d.
[0038] Furthermore, the transverse springs 11a-11d are arranged between an associated transverse stop 12a-12d and the associated longitudinal cross member 4a, 4b. The transverse stops 12a-12d are also arranged on the cross members 3a, 3b. The first and second transverse stops 12a, 12b are arranged on the first cross member 3a, and the third and fourth transverse stops 12c, 12d are arranged on the second cross member 3b. With the aid of the transverse stops 12a-12d, the longitudinal cross members 4a, 4b can be spring-mounted against the cross members 3a, 3b in the transverse direction Y by means of the transverse springs 11a-11d.
[0039] The transverse stop 12 can also limit the movement of the longitudinal cross member 4 in the transverse direction Y. The longitudinal cross member 4 can abut against the transverse stop 12 or does abut against it. The longitudinal cross member 4 is guided in the transverse direction Y by the at least one transverse stop 12. A transverse stop 12 can also be arranged on both longitudinal sides 13, 14 of the longitudinal cross member 4, so that the longitudinal cross member 4 is guided on both sides in the transverse direction Y. If the at least one transverse spring assembly 11 is arranged between the longitudinal cross member 4 and the at least one transverse stop 12, the longitudinal cross member 4 is guided in the transverse direction Y in a spring-loaded manner.
[0040] The longitudinal cross members 4a, 4b each have a first and a second longitudinal cross member end 15, 16. In the region of the respective longitudinal cross member ends 15, 16, the longitudinal cross members 4a, 4b are arranged on the cross members 3a, 3b. The two first longitudinal cross member ends 15a, 15b of the two longitudinal cross members 4a, 4b are arranged on the first cross member 3a, and the two second longitudinal cross member ends 16a, 16b of the two longitudinal cross members 4a, 4b are arranged on the second cross member 3b.
[0041] Furthermore, the longitudinal cross members 4a, 4b have an inner longitudinal side 13 and an outer longitudinal side 14. The longitudinal sides 13, 14 are designated inner and outer longitudinal sides 13, 14 because the inner longitudinal side 13 faces an undesignated center of the chassis 1. The inner longitudinal side 13 faces the interior. The outer longitudinal side 14 is arranged on the side facing away from the center of the chassis 1, namely facing outwards. If, in an alternative exemplary embodiment, a longitudinal cross member 4 is arranged in the center in the transverse direction, the inner and outer longitudinal sides 13, 14 can also be designated first and second longitudinal sides 13, 14.
[0042] In the exemplary embodiment shown here, the transverse springs 11a - 11d are arranged between the outer longitudinal side 14a, 14b and the transverse stops 12a - 12d. The transverse stops 12a - 12d are also arranged on the side of the longitudinal cross members 4a, 4b facing the outer longitudinal side 14a, 14b. Additionally or alternatively, the transverse springs 11 or at least one of the transverse springs 11 can be arranged between the inner longitudinal side 13a, 13b and a transverse stop 12 arranged on a side of the longitudinal cross member 4a, 4b facing the inner longitudinal side 13a, 13b. Such a transverse stop 12 is thus arranged in the transverse direction Y between the two longitudinal cross members 4a, 4b shown here. For example, if a transverse spring 11 is arranged on both longitudinal sides 13, 14 and in the area of each longitudinal cross member end 15, 16, a total of eight transverse springs 11 are present. The cross member system 10 shown here then comprises these eight transverse springs 11.
[0043] According to the present embodiment, a crossbeam 17 is arranged between the two longitudinal crossbeams 4a, 4b. A vehicle cabin 18 of the hovercraft 9 can be coupled to the chassis 1 by means of the crossbeam 17. Advantageously, a crossbeam 17 is also arranged between the two longitudinal crossbeams 4c, 4d of Figure 1. Thus, the first and second crossbeam systems 10a, 10b can have a crossbeam 17 between the respective longitudinal crossbeams 4a-4d.
[0044] The crossbeams 17 can have receiving means 19a - 19d, by means of which the vehicle cabin 18 can be mounted on the crossbeam 17. Here, four receiving means 19a - 19d are arranged on the crossbeam 17. The receiving means 19a - 19d can, for example, be pins or shafts, by means of which the vehicle cabin 18 can be pivotally mounted. This can ensure that the vehicle cabin 18 can roll, i.e., the vehicle cabin 18 can rotate in a longitudinal direction. This can ensure that the vehicle cabin 18 is held horizontally even on a laterally inclined route. A receptacle 20, in particular in the form of a strut, can be arranged on each receiving means 19a - 19d, which supports the vehicle cabin 18 (see Figure 4). Figure 3 shows a cross-section through the chassis 1. For example, the cutting plane lies in the second cross-beam 3b looking towards the first cross-beam 3a.For the sake of simplicity, not all features will be discussed here if they are already known from the previous figures.
[0045] According to the present embodiment, transverse springs 11c, 11e, 11f, 11d are arranged in the transverse direction Y on both longitudinal sides 13a, 13b, 14a, 14b of the two longitudinal cross members 4c, 4d. This allows vibrations to be better cushioned, dampened, and / or absorbed.
[0046] Furthermore, a transverse stop 12c, 12e, 12f, 12d is arranged on each of the two longitudinal sides 13a, 13b, 14a, 14b of the two longitudinal cross members 4c, 4d.
[0047] Furthermore, the chassis 1 has at least one first horizontal spring 21. Two first horizontal springs 21a, 21b are shown here. The at least one first horizontal spring 21 is arranged between the longitudinal cross member 4 or between the longitudinal cross members 4a, 4b and the cross member 3 or the cross members 3a, 3b. As a result, the longitudinal cross members 4 are sprung relative to the cross members 3 in the horizontal direction or in the vertical direction Z.
[0048] Additionally or alternatively, the chassis 1 shown here comprises a second horizontal suspension 22. Two second horizontal suspensions 22a, 22b are shown here. The second horizontal suspension 22 or the two second horizontal suspensions 22a, 22b are arranged between the crossbeam 3 or between the crossbeams 3 and the suspended frames 2. As a result, the crossbeams 3 are sprung relative to the suspended frames 2 in the horizontal direction or in the vertical direction Z.
[0049] Also shown in this view are the receiving means 19c, 19d. These are round and / or can be designed as shafts or bolts. The receptacles 20, on which the vehicle cabin 18 is mounted, are arranged on the receiving means 19.
[0050] The receiving means 19 are arranged, as can be seen here, on the crossbeam 17. The crossbeam 17 is arranged in a central region, preferably in the middle, of the longitudinal cross members 4.
[0051] Figures 2 and 3 show a truss system 10. The two truss systems 10a, 10b, as shown in Figure 1, can be structurally identical to one another and can further include the same features.
[0052] Figure 4 shows a side view of the hover vehicle 9. Five hover frames 2 of a row 7, 8 of hover frames 2 are visible. The vehicle cabin 18 is arranged on the chassis 1. The mounts 20a, 20b connect the chassis 1 to the vehicle cabin 18.
[0053] 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.
