Description

Technical Field

[0001] The present invention relates to a support skid for a levitation vehicle constrained by a track in a maglev train, comprising a spring element for elastically placing the levitation vehicle on the track. Background Technology

[0002] An emergency skid for high-speed express trains is known from DE 2536575 C3, comprising multiple sliders mounted on the high-speed railway via a suspension system and a buffer. Furthermore, a lever is installed between the emergency skid and the vehicle to introduce frictional forces to the vehicle. Summary of the Invention

[0003] Therefore, the purpose of this invention is to eliminate the known disadvantages of the prior art.

[0004] This objective is achieved through a support skid and suspension vehicle with features that have the scope of an independent patent application.

[0005] This invention proposes a support skid for a maglev train's track-bound levitation vehicle, which is a magnetically levitation vehicle suspended above the track by magnetic force. During operation, the levitation vehicle has no contact with the track and can move freely relative to it. The levitation vehicle can be lifted by magnetic force until it is suspended above the track.

[0006] When the maglev train is not in operation, the support skid must still be used or required to place the levitated vehicle on the track; during the operation of the maglev train, that is, when the levitated vehicle is moving, if the drive fails and the levitated vehicle can no longer be lifted and placed on the track by magnetic force, the support skid can also be used as an emergency support skid.

[0007] The support skid also has a spring element to elastically place the suspended vehicle on the track.

[0008] According to the invention, the spring element is designed as a spring block, particularly a solid spring body, and / or as an elastomer, particularly a rubber body. The spring block can have, for example, a square or circular basic shape. With the aid of the spring block and / or elastomer, the suspended vehicle can be lowered or placed on the track in an elastic manner. Furthermore, if the suspended vehicle is still moving while placed on the track, braking force can be exchanged via the spring block and / or elastomer, after which the spring element can transmit braking force to the suspended vehicle to bring it to a stop. In the event of, for example, a power outage and the suspended vehicle being lowered onto the track, the support skid can be used as an emergency operating skid. The support skid can be designed to be simpler and more compact with the aid of the spring block and / or elastomer.

[0009] The spring element is designed to be stiffer in the longitudinal direction than in a first lateral direction, where the longitudinal direction is parallel to the track when the supporting skid is in use as intended, and the first lateral direction is the direction in which the suspended vehicle is elastically lowered. When the suspended vehicle is lowered onto the track, the weight of the suspended vehicle also acts along the first lateral direction.

[0010] Advantageously, the spring element is a rubber spring or a rubber-metal spring.

[0011] Advantageously, when the support skid is used as specified, the support skid has a skid element on the track-facing side. Since the skid element is located on the track-facing side of the support skid, it comes into contact with the track during descent; the skid element is stiffer than the spring element or elastic spring block and / or elastomer, thereby reducing wear on the skid element, especially when the suspended vehicle is still moving while the support skid is placed on the track. The skid element can be made, for example, of metal and / or ceramic, and is particularly screwed onto the spring block and / or elastomer; when the support skid is used as specified, the skid element is positioned between the track and the spring element or elastic spring block and / or elastomer; the skid element can also be a sliding element. Preferably, the skid element is detachably connected to the spring element, particularly by a screw connection.

[0012] Advantageously, the support sled has a receiving element disposed thereon; additionally or alternatively, the receiving element may be connected to a spring element or a spring block and / or an elastomer; additionally or alternatively, the receiving element may be disposed between the sled element and the spring element, the sled element being connected to the spring element by means of the receiving element.

[0013] Alternatively or additionally, the skid element may be connected to the elastic spring block and / or elastomer and / or receiving element in a form-fit and / or force-fit manner, so that when it descends onto the track, the skid element can transmit braking force to the receiving element and continue to transmit it to the suspended vehicle, thereby bringing the suspended vehicle to a stop.

[0014] Advantageously, the receiving element surrounds the skid element on at least one end face, or the receiving element may surround the skid element on both end faces; the receiving element may surround the skid element in a form-fitting manner on at least one end face, thereby receiving the skid element without gaps. The two end faces are spaced apart from each other in the longitudinal direction of the supporting skid.

[0015] Additionally or alternatively, it is advantageous if the receiving element surrounds the skid element on at least one longitudinal side; wherein the receiving element may also surround the skid element on two longitudinal sides, and the receiving element may also surround the skid element in a form-fitting manner on at least one longitudinal side.

[0016] Advantageously, the skid element is detachably connected to the receiving element, whereby the skid element can be replaced when it wears out; for example, the skid element can be fixed to the receiving element by screws.

[0017] Alternatively or additionally, it is advantageous to provide a spacer between the skid element and the receiving element; if the skid element is partially worn, the worn skid element will be thinner than the undamaged skid element, and the skid element can be pushed out of the receiving element again through the spacer.

[0018] Advantageously, the support skid has a connecting element for connecting the support skid to the suspended vehicle; when the support skid is used as specified, the connecting element is located on the vehicle side of the support skid away from the track side. Furthermore, a spring element may be located between the receiving element and the connecting element and is located on the connecting element.

[0019] Advantageously, the connecting element has at least one fixing element through which the support skid can be connected to the suspension vehicle, wherein the fixing element can be a screw-in member, thereby allowing the support skid to be screwed to the suspension vehicle.

[0020] Advantageously, the spring element and / or skid element has at least one groove, particularly as a slot and / or hole, preferably extending completely through the spring element and / or skid element, particularly from a first side to an opposing second side; additionally or alternatively, the at least one groove extends at least partially from the track side of the spring element and / or skid element to the vehicle side; additionally or alternatively, the at least one groove may be transverse to and / or parallel to the longitudinal direction of the supporting skid. The elasticity of the spring element and / or skid element, particularly its elasticity in the longitudinal direction of the supporting skid, can be adjusted by the at least one groove.

[0021] Advantageously, the spring element has a fixing portion for fixing the skid element; additionally or alternatively, the spring element has at least one stop portion adjacent to the fixing portion in the longitudinal direction of the supporting skid; in particular, the spring element includes two stops portions, and the fixing portion is disposed between the two stops portions; preferably, the skid element is fixed to the spring element in the fixing portion rather than in the stops portion.

[0022] Advantageously, the at least one groove is formed between the fixing part and the stop part; additionally or alternatively, it is advantageous if the groove is arranged and / or designed such that the groove separates the fixing part from the corresponding stop part in at least some areas, so that the fixing part can move relative to the stop part in the longitudinal direction of the support skid.

[0023] Advantageously, the support skid includes a non-elastic stop, particularly a metal stop, which is disposed on the stop portion of the spring element and located on the side of the stop portion opposite to the fixed portion.

[0024] The present invention also provides a levitation vehicle, including a plurality of support skids for placing the levitation vehicle on a track, wherein the maglev train includes the track.

[0025] The suspended vehicle also includes, for example, a chassis and at least one passenger compartment disposed thereon; the chassis includes, for example, a short stator asynchronous linear motor for lifting and / or driving the suspended vehicle; the support skid may also be disposed on the chassis.

[0026] According to the present invention, at least one support skid is designed according to one or more of the features described above and / or below.

[0027] Advantageously, the suspended vehicle has multiple suspended frames connected to form a chassis, wherein the suspended frames are interconnected by at least one hinge; the chassis extends longitudinally along the suspended vehicle, wherein the suspended frames are also interconnected longitudinally; the chassis can be bent by the hinges between the suspended frames, thereby enabling the suspended vehicle to travel through curves.

[0028] Advantageously, a support skid is provided between every two adjacent suspension frames in the longitudinal direction of the chassis, wherein the support skid is connected to the two adjacent suspension frames, thereby one support skid can cushion the two suspension frames.

[0029] Advantageously, the support skid is mounted on a support element of the chassis, and each support element is mounted on one of the two adjacent suspension frames via a support element end, thus bridging the two adjacent suspension frames, and the support skid is mounted on the support element. Furthermore, the support element can be connected to at least one of the two suspension frames via a swivel joint, thereby allowing the travel path to bend for turning.

[0030] Advantageously, at least one support skid is directly connected to the suspension frame via a swivel joint, thereby allowing the support skid to rotate for turning.

[0031] Alternatively or additionally, at least one support skid is securely, particularly in a rotatably fixed manner, to a suspension frame, whereby the fixed support skid can easily transmit braking force when descending to the track.

[0032] Advantageously, at least one, and especially all, of the suspension frames have two support skids, whereby the suspension frame can be stably lowered onto the track, wherein the support skids can be positioned at the ends of the respective suspension frames such that the support skids are spaced apart from each other in the longitudinal direction.

[0033] Further advantages of the invention are described in the following examples. Attached Figure Description

[0038] Figure 5 This is a side view of a suspended vehicle with a chassis, which has multiple support skids. Detailed Implementation

[0039] Figure 1 A suspended vehicle 24 constrained by a track for a maglev train is shown (see Figure 5 The diagram shows a side cross-sectional view of the support skid 1. The maglev train also includes a track on which the levitation vehicle 24 can levitate and move using magnetic force. When the levitation vehicle 24 is levitating and / or moving, the support skid 1 is spaced apart from the track; conversely, if the maglev train stops operating or, for example, a power failure occurs while the levitation vehicle 24 is moving and the levitation vehicle 24 is thus placed on the track, the support skid 1 is used to place the levitation vehicle 24 on the track while the levitation vehicle 24 can still move; the support skid 1 must therefore also transmit braking force to the levitation vehicle 24.

[0040] To allow the suspended vehicle 24 to descend elastically to the track, the support skid 1 has a spring element 2 designed as an elastic spring block and / or elastomer. This spring element 2, designed as an elastic spring block and / or elastomer, has the advantage of absorbing the compressive force Fd generated by the weight of the suspended vehicle 24. The compressive force Fd, as shown here, acts along the direction from the vehicle side 4 of the support skid 1 towards the track side 3 of the support skid 1. When the support skid 1 is used as specified, i.e., when the support skid 1 is set on the suspended vehicle 24, the vehicle side 4 faces the suspended vehicle 24 and the track side 3 faces the track. This means that the spring element 2 must elastically cushion the weight of the suspended vehicle 24 as it descends. The support skid 1 also has a first lateral direction Z, which is parallel to the direction from the vehicle side 4 to the track side 3. When the support skid 1 is set on the suspended vehicle 24, the first lateral direction Z is vertical or along the direction in which the compressive force Fd acts.

[0041] Furthermore, the support skid 1 also has a longitudinal direction X, which is parallel to the track and therefore parallel to the direction of travel of the suspended vehicle 24 when the support skid 1 is used as specified, while the first lateral direction Z is transverse to the longitudinal direction X. If the suspended vehicle 24 is lowered onto the track while still in motion, the braking force acting on the longitudinal direction X between the track and the suspended vehicle 24 can also be exchanged by means of a spring element 2 designed as an elastic spring block and / or an elastomer, which can therefore absorb the compressive force Fd and braking force parallel to the longitudinal direction X.

[0042] The spring element 2, designed as an elastic spring block and / or an elastic body, can be, for example, an elastic body or rubber.

[0043] Furthermore, it may be advantageous if the elasticity of spring element 2 in the direction of the compressive force Fd, i.e., from the vehicle side 4 towards the track side 3, is higher than its elasticity in the longitudinal direction X. This allows the elasticity of spring element 2 along the first transverse direction Z to be higher than its elasticity along the longitudinal direction X, which is advantageous because the braking force is generally greater than the compressive force Fd, especially when the suspended vehicle 24 descends onto the track at a high speed, for example, exceeding 200 km / h. Higher elasticity, for example, means that spring element 2 is softer compared to lower elasticity. Therefore, the elasticity of spring element 2 depends on the direction.

[0044] According to this embodiment, the support skid 1 has a skid element 5 disposed on the track side 3 of the support skid 1. When the levitated vehicle 24 descends, the skid element 5 contacts the track. The skid element 5 may also be a sliding element with high rigidity, allowing the support skid 1 to slide on the track; the skid element 5 is made of, for example, metal and / or ceramic; furthermore, the skid element 5 is connected to the spring element 2, thereby allowing the braking force to continue to be transmitted to the levitated vehicle 24.

[0045] According to this embodiment, the support sled 1 includes a receiving element 6, and the sled element 5 is connected to the spring element 2 through the receiving element 6.

[0046] The skid element 5 also has a first and second end face 9, 10, which are spaced apart from each other in the longitudinal direction X; advantageously, as shown herein, the receiving element 6 surrounds the skid element 5 on the first end face 9 and / or the second end face 10, thereby facilitating the transmission of braking force between the skid element 5 and the receiving element 6.

[0047] As shown here, the skid element 5 is disposed on the receiving element 6 and the receiving element 6 is disposed on the spring element 2 by means of screws 11a-11d, by means of which the skid element 5 can be unscrewed when it wears out.

[0048] In addition, the support skid 1 also includes a connecting element 7 for connecting the support skid 1 to the suspension vehicle 24. The connecting element 7 includes two fixing elements 8a and 8b, through which the support skid 1 can be mounted on the suspension vehicle 24. The two fixing elements 8a and 8b are designed as screws. The connecting element 7 is also connected to the spring element 2.

[0049] Advantageously, the spring element 2 has at least one groove 12a, 12b, particularly a spring slot, which can be designed, for example, as a groove or a hole, depending on... Figure 1 The spring element 2 has two grooves 12a and 12b. The spring element 2 can be deformed and / or bent in the longitudinal direction X by means of the at least one groove 12a and 12b. The elasticity in the longitudinal direction X can be adjusted by means of the at least one groove 12a and 12b. For example, the spring constant in the longitudinal direction X of the spring element 2 can be gradually formed by means of the at least one groove 12a and 12b. If the spring element 2 is deformed in the longitudinal direction X until the at least one groove 12a and 12b is bridged, the spring element 2 is bent as a whole, and the spring constant can therefore be increased.

[0050] The grooves 12a and 12b extend at least partially from the side of the spring element 2 facing the track side 3 toward the vehicle side 4; furthermore, the at least one groove 12a and 12b preferably extends completely through the spring element 2 in a second transverse direction Y relative to the longitudinal direction.

[0051] from Figure 1 It can be seen that, in particular, the spring element 2, which is an elastic body, has a fixing part 32 for fixing the skid element 5. The spring element 2 has at least one stop part 33, 34, which is adjacent to the fixing part 32 in the longitudinal direction of supporting the skid. In this embodiment, the spring element 2 includes two stop parts 33, 34, and the fixing part 32 is disposed between the two stop parts. The skid element 5 is fixed to the spring element 2 in the fixing part 32 rather than in the stop parts 33, 34.

[0052] At least one groove 12a, 12b is formed between the fixing part 32 and the corresponding stop parts 33, 34. The grooves 12a, 12b are arranged and / or designed such that the grooves 12a, 12b separate the fixing part 32 and the corresponding stop parts 33, 34 in at least some areas, thereby allowing the fixing part 32 to move longitudinally relative to the corresponding stop parts 33, 34 relative to the longitudinal direction of the support skid 1.

[0053] according to Figure 1The support skid 1 includes at least one inelastic stop 35, 36, particularly as a metal stop, which may be part of the connecting element 7; the stop 35, 36 is disposed on the corresponding stop portions 33, 34 of the spring element 2 and is located on the side of the stop portions 33, 34 opposite to the fixing portion 32. According to this embodiment, the support skid 1 includes a first stop 35 belonging to the first stop portion 33 and a second stop 36 belonging to the second stop portion 34.

[0054] Furthermore, according to this embodiment, the skid element 5 has at least one skid groove 13a, 13b; with the help of the at least one skid groove 13a, 13b, when the skid element 5 is lowered onto the track during the movement of the levitation vehicle 24, heat can be dissipated.

[0055] The at least one skid groove 13a, 13b extends at least partially from the track side 3 toward the vehicle side 4; furthermore, the at least one skid groove 13a, 13b extends completely through the skid element 5 in a second transverse Y relative to the longitudinal direction.

[0056] Furthermore, in this embodiment, the receiving element 6 has a recess 26, while the spring element 2 has a protrusion 27, which is provided on the recess 26 in a form-fitting manner, thereby allowing braking force to be transmitted to the spring element 2.

[0057] In addition, the receiving element 6 has a first leg 28 and a second leg 29 spaced apart from it in the longitudinal direction X. The first leg 28 surrounds the skid element 5 on its first end face 9, and the second leg 29 surrounds the skid element 5 on its second end face 10. The skid element 5 is surrounded by the receiving element 6 by at least one leg 28, 29.

[0058] Figure 2 A cross-sectional schematic diagram of the support skid 1 as viewed from the front is shown.

[0059] 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.

[0060] The skid element 5 has a first longitudinal side 14 and a second longitudinal side 15, which are spaced apart from each other in the second transverse Y. According to this embodiment, the skid element 5 is surrounded by the receiving element 6 on the first and second longitudinal sides 14, 15, and the skid element 5 is connected to the receiving element 6 in a form-fitting and / or force-fitting manner.

[0061] According to this embodiment, a pad element 16 is disposed between the skid element 5 and the receiving element 6 along the first transverse direction Z; when the skid element 5 is partially worn, the pad element 16 can be disposed between the skid element 5 and the receiving element 6, thereby achieving that all the supporting skids 1 of the suspended vehicle 24 have the same extension in the first transverse direction Z (which can be called the height direction Z), so that the suspended vehicle 24 can be uniformly lowered onto the track.

[0062] According to this embodiment, the fixing element 8 for fixing the support skid 1 to the suspension vehicle 24 is designed as a threaded hole with internal threads.

[0063] According to this embodiment, the receiving element 6 has a third leg 30 and a fourth leg 31. The third leg 30 surrounds the skid element 5 on its first longitudinal side 14, and the fourth leg 31 surrounds the skid element 5 on its second longitudinal side 15. The at least third and / or fourth legs 30, 31 at least partially surround the skid element 5, thereby the four legs 28-31 (see Figure 1 and Figure 2 It can completely surround the skid element 5.

[0064] Figure 3 A schematic diagram of the chassis 17 of the suspended vehicle 24 with supporting skids 1a-1d is shown.

[0067] The suspension frames 18a and 18b shown here each have a first suspension frame end 20a and a second suspension frame end 20b. The second suspension frame end 20b of the first suspension frame 18a is adjacent to the first suspension frame end 20a of the second suspension frame 18b, and this situation continues throughout the entire longitudinal direction X.

[0068] The suspension frames 18a, 18b shown here, especially all the suspension frames 18 of the chassis 17, each have two support skids 1a-1d, and each support skid 1a-1d is provided in the region at the end 20a, 20b of each suspension frame; since the chassis 17 may include a total of ten suspension frames 18, the chassis 17 may also include twenty support skids 1.

[0069] It is also schematically shown here that the support skid 1 is screwed to the suspension frame 18.

[0072] In this embodiment, the support skid 1 is mounted on the support element 21, which extends like a bridge between two adjacent suspension frames 18a and 18b in the longitudinal direction X. The support element 21 is thus connected to the two suspension frames 18a and 18b. The support element 21 also has a first support element end 23a and a second support element end 23b. The first support element end 23a is mounted on the first suspension frame 18a, and the second support element end 23b is mounted on the second suspension frame 18b.
