Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a structure of a mechanical braking device (braking device) of a magnetically levitated railway and a mounting structure thereof.
[0002]
[Prior art]
The brake means in the attraction-type vehicle traveling system known as a magnetically levitated railway is obtained by controlling a linear motor that is a thrust means of the vehicle, and in addition, a broad mechanical brake device that holds the rail with a pair of friction materials ( It is common to use a brake device that presses the friction material against the rail. This mechanical brake device is different in the system from a brake device in a general railway or automobile that brakes rotation of a wheel rolling on a rail or road surface, and is connected to a vehicle body by a buffer spring or the like. It has a structure and action peculiar to a magnetically levitated railway in which a braking force action is obtained by holding the ground-side rail with a friction material provided in a so-called unsprung structure.
[0003]
The mechanical brake device used in this magnetically levitated railway is generally a hydraulically operated type using a hydraulic cylinder. For example, a pair of friction materials disposed opposite to each other with a rail interposed therebetween are arranged on both sides. Opposed type that presses against the rail by the hydraulic piston placed on the one side, the hydraulic piston is placed against the friction material on one side, and the cylinder member is floated and pressed on the opposite side by the pressing reaction force of the one side friction material A caliper floating type is known.
[0004]
8 to 10 show an example of the floating type brake device, in which 100 is a caliper, in which the hydraulic cylinder portion 101 is arranged on one side of the rail 200 and the vehicle side. The through-hole 102 formed in the caliper 100 slides on the guide pin 301 fixed at both ends to the mounting bracket 600 (see FIG. 10) fixed to the fixed portion (magnet core) 300, so that the lateral direction of the rail 200 (rail A structure in which the arm portion 103 is extended from the hydraulic cylinder portion 101 to form a reaction portion 104 on the opposite side of the rail 200 so as to be slidable (floating) in a horizontal direction perpendicular to the extending direction. Is provided. In this example, two sets of sliding portions of the guide pin 301 and the through-hole 102 are also provided to serve as a detent for the caliper 1, and the caliper 1 and the vehicle side are provided to place the caliper in a neutral position when not braked. Neutral positioning springs 400 and 400 are stretched between the fixed portions 300. Reference numeral 500 denotes a pair of friction materials disposed so as to face the rail 200, and one side (hereinafter referred to as “inner side”) friction material 500. ₁ Is assembled to the tip of the hydraulic piston 105 and the opposite side (hereinafter referred to as “outer side”) friction material 500. ₂ Is assembled to the reaction portion 104. In addition, each arm part 200 of the rail 200 provided in the reverse U shape similarly to a general attraction type magnetic levitation type vehicle traveling system. ₁ , 200 ₂ On the other hand, the arm portions of the magnet core 3 of the U-shaped levitation electromagnet are provided so as to face each other, but the position in FIG. 8 indicates the portion indicated by the line AA in FIG. On the outside (right side in FIG. 8), a notch 306 is formed for removing the brake device, and a mounting portion for the guide pin 301 is formed by the mounting bracket 600.
[0005]
In the above-described configuration, the pair of friction members 500 are connected to the bracket 302 provided on the magnet core 300 as shown in FIG. 10 in order to transmit a braking force generated by pressing (pressing) the rails 200 to the rail 200 to the vehicle side. A thrust link 303 is installed between them.
[0006]
The caliper floating type brake device described above has a hydraulic cylinder only on one side, and therefore, the magnetic levitation railway in which reduction of vehicle weight is important is advantageous in that the device is smaller and lighter than the opposed type.
[0007]
[Problems to be solved by the invention]
However, even in the brake device illustrated in FIGS. 8 to 10, problems to be further improved are pointed out.
[0008]
That is, the mechanical brake device is an extremely important safety part and device for ensuring safe traveling control, and requires periodic inspection, maintenance and replacement work of friction materials. For this reason, it is desired that the work of disassembling and reassembling the apparatus can be performed as easily as possible.
[0009]
However, in the suction type vehicle traveling system of the magnetic levitation railway, the brake device is directly applied to the rail 200 laid on the ground side as described above, and the magnet core 300 or the like for assembling the brake device is used. The unsprung structure is an assembly part of the most important levitation magnet (not shown) in the system for levitation magnetic attraction, and the distance between the rail and the levitation magnet is about 10 mm or less even when not levitating. In view of the fact that there is only a narrow gap, it is structurally not easy to disassemble, remove and reassemble the brake device described above. In order to facilitate this work, a large notch (306 shown in FIG. 10) is formed in the brake device assembly portion (magnet core or the like), and the mounting bracket 6 attached with the mounting bolt 307 is removed to remove the brake device. Although it is necessary to make it possible to remove the caliper 100, which is the main body, it is necessary to allow the caliper 100 to be removed.
[0010]
Therefore, it is strongly desired to realize the above-described work of disassembly / removal and reassembly of the brake device without reducing the strength and rigidity of the important part.
[0011]
In addition, since the brake device holds a ground-side rail that does not move as a part of the unsprung structure portion of the traveling vehicle, the brake device follows the vehicle-side vibration, etc. As a result, the friction between the friction material and the rail at the time of braking is uneven, and so-called uneven wear occurs, causing braking failure at the time of normal braking or causing the friction material to be prematurely consumed. (See FIG. 9).
[0012]
Furthermore, if vibrations caused by irregularities on the rail surface (surface irregularities) or laying accuracy (commonly called “passing accuracy”) are transmitted to the vehicle side without being attenuated via the braking device in the braking state, There is a problem that the ride comfort on the vehicle side is remarkably impaired as abnormal vibration.
[0013]
Accordingly, there is a demand for a brake device structure and an assembly structure that can suppress relative posture fluctuations and vibration transmission between the rail and the vehicle side as much as possible.
[0014]
Furthermore, when the vehicle is lifted and landed when the brake is activated, the brake device (unsprung structure) that is substantially fixed to the rail by holding the friction material has a push-up force caused by the vertical movement of the vehicle. The pressing force acts and the load concentrates on the brake device assembly part of the unsprung structure, so the rigidity of the same part is necessary to prevent damage to the structural part and to suppress deformation. Therefore, this causes a problem of weight increase. However, in the magnetically levitated traveling system, the weight reduction of the vehicle is rather one of the most important issues.
[0015]
Therefore, there is a demand for a structure and an assembly structure of a brake device that can prevent damage and suppress deformation while suppressing an increase in weight as much as possible.
[0016]
The present invention provides a brake device having a structure that can solve various problems as described above and can be suitably applied to a suction vehicle traveling system of a magnetically levitated railway.
[0017]
[Means for Solving the Problems]
One of the features of the brake system for a magnetically levitated railway according to the present invention that achieves the above object is a rail fixed to the ground side, and a levitating electromagnet that faces the rail and floats the vehicle by the action of magnetic attraction. And a brake device having a pair of friction materials disposed on both sides of the rail so as to be able to generate a braking force by sandwiching the rail, and a vehicle-side strength structure that supports the levitation electromagnet and the brake device The brake device includes a caliper that presses one of the pair of friction materials against the rail by the cylinder device and moves the rail in the lateral direction by the pressing reaction force to press the other friction material against the rail. In the magnetically levitated railway configured to have the brake device, the brake device is a fastening means capable of attaching and detaching the divided body spaced apart with the strength structure therebetween The caliper is formed by integration, and the guide pin is fitted and slid into a sliding hole formed in one of the caliper and the strength structure and fixed to either the caliper or the strength structure. Thus, the movement guide means for guiding the movement of the caliper in the lateral direction of the rail is configured.
[0018]
One of the reasons for adopting such a configuration in the present invention is as follows. That is, in the attraction type magnetic levitation type vehicle traveling system, the magnet core of the levitation electromagnet on the vehicle side faces this rail with a minute gap, regardless of whether the rail is an inverted U shape or any other shape. Therefore, when the magnet core is used as a strength structure on the vehicle side, the facing state in the minute gap is not desirable. This is because a configuration that enables assembly of the brake device while securing it is desired, and it has been understood that the above configuration is suitable for satisfying such a request.
[0019]
By adopting such a configuration, the integrated caliper, which can also be called the main body of the brake device, can be separately taken out into the above-mentioned divided bodies that are small elements by removing the fastening means. The structure can be taken out without being constrained by the structure of the strength structure or without giving a restriction to provide a notch in the structure of the strength structure. More specifically, for example, when the fastening means is constituted by bolts and nuts and the bolts are passed through the strength structure on the vehicle side, the caliper parts are separated by removing the nuts and pulling out the bolts. Therefore, the work of disassembling and reassembling the brake device becomes extremely easy.
[0020]
In the above configuration, a hydraulic or pneumatic piston-cylinder is used as the cylinder device that presses one friction material of the brake device against the rail. However, the present invention is not limited to this.
[0021]
Examples of the strength structure in the present invention include, but are not limited to, a so-called unsprung structure frame and a magnet core of a floating electromagnet.
[0022]
Another feature of the present invention is that, in the above-described configuration, a sliding hole formed in one of the caliper and the strength structure constituting the movement guide means, and a guide pin fitted into and sliding on the sliding hole A configuration in which at least two sets of the above are provided, and an elastic body is interposed in the sliding hole and the guide pin sliding portion so as to allow relative translation and relative tilting of both shaft cores. It is in the place of making.
[0023]
By configuring in this way, the friction material firmly holds it during braking, so that even if the caliper is substantially fixed to the rail side, the caliper is held via the movement guide support means. The strength structure such as a magnet core on the vehicle side that is supported is absorbed and buffered by the relative deformation and inclination of both of them due to the elastic deformation of the elastic body of the moving guide support means interposed between the calipers. Therefore, an unreasonable load does not act, and therefore the burden on the design strength of a strength structure such as a magnet core is reduced.
[0024]
Furthermore, since the caliper vibration and the like due to irregularities in the rail surface are absorbed and buffered by this elastic body, it is also possible to prevent this from being transmitted to the vehicle body side.
[0025]
Further, in the present invention, in short, “a sliding hole is formed in one of the caliper and the strength structure, and on the other hand, a guide pin that fits and slides into the sliding hole is fixed to either the caliper or the strength structure. The configuration is specified in the form of “to do”, even if the guide pin is fixed at both ends to the caliper and is slid into the sliding hole of the strength structure at the intermediate portion. This is because the object of the present invention can be sufficiently achieved by any of the types in which the strength is fixed to the strength structure and both ends are slid into the sliding holes of the caliper. Since it can be used also as a fastening means for the divided body, the former type in which both ends of the guide pin are fixed to the caliper is preferably employed.
[0026]
The elastic body interposed between the sliding hole and the guide pin sliding portion may be of a type in which the elastic body slides on the sliding sliding surface. It is preferable to provide a cylindrical member to be formed and provide the elastic body as a backing material so that the position and posture of the cylindrical member can be displaced.
[0027]

[0033]
In these drawings, reference numeral 81 denotes a caliper of a brake device, which includes three pairs of fastening means composed of bolt members and nut members described below, and a pair of divided bodies 82 and 83 arranged on both sides of the magnet core 6a. It is integrated by fastening. That is, as shown in FIG. 3, the first and second fastening means in this example are arranged in parallel at a substantially intermediate position in the vertical direction of the caliper 81, and the sleeve 84 penetrating the magnet core 6a has both ends thereof as described above. Engagement with the inner surfaces 82a and 83a of the pair of divided bodies restricts the approach of the divided bodies 82 and 83, and penetrates the through holes 82b and 83b formed in the divided bodies 82 and 83 and the sleeve 84. By the fastening of the bolt member 85 and the nut member 86 screwed into the tip screw portion thereof, the divided bodies 82 and 83 are fastened in such a manner that the sleeve 84 is fastened. Further, the third fastening means includes a pair of divided bodies 82, on both side screw portions of a long nut member 87 held between the lower ends of the divided bodies 82, 83 extending to the lower side of the magnet core 6 a. , 83, and bolt members 82d and 83d inserted through through holes 82c and 83c are fastened.
[0034]
By these first to third fastening means, the pair of divided bodies 82 and 83 become a single caliper 81 integrated. Reference numeral 83e denotes a piston that is slidably engaged with the cylinder 83f. When the pressure air from an air pressure source (not shown) is supplied through the supply pipe 83g, the friction material 12 is provided. ₂ Is pressed against the rail 2.
[0035]
The feature of this example is that the sleeve 84 of the first and second fastening means configured as described above also serves as a guide pin that can move in the axial direction with respect to the through hole of the magnet core 6a. 84 (hereinafter referred to as “guide pin” in view of its function) is configured such that radial movement and tilting of the shaft center are allowed with respect to the magnet core 6a.
[0036]
That is, the magnet core 6a is configured such that, for example, a rubber cylindrical elastic body 88 is fitted to the inner peripheral surface 6b of the through hole formed so that the guide pin 84 passes therethrough. A short cylindrical bearing member 89 made of a rigid material such as a metal material is fitted to the inner periphery, and the cylindrical slide bearing member 89 is slidable on the outer periphery of the guide pin 84 so as to be axially movable (slidable). It is configured to match. The rubber cylindrical elastic body 88 is an annular elastic body 90 that engages with both side walls of the through hole of the magnet core 6a. ₁ , 90 ₂ And washer 91 ₁ , 91 ₂ A nut 92 that is screwed to a thread portion formed on the outer periphery of the cylindrical bearing member 89 via ₁ , 92 ₂ To prevent it from coming off.
[0037]
93 ₁ , 93 ₂ Is a pair of neutral position holding springs for holding the caliper 81 in the neutral position during non-braking, and is stretched between the magnet core 6a and the pair of divided bodies 82 and 83.
[0038]
FIG. 5 is a diagram showing in more detail the configuration of the portion that supports the guide pin (sleeve 84) of the brake device 8 configured as described above. The sliding surface of the sliding surface between the guide pin 84 and the slide bearing member 89 is shown in FIG. Protective boot 94 to keep the mobility always good ₁ , 94 ₂ Are installed as shown in order to seal these sliding surfaces from the outside air.
[0039]
In the brake device having the above configuration, the divided bodies 82 and 83 constituting the caliper 81 are small if the engagement relationship between the bolts and the nuts constituting the first to third fastening means is removed. Since it is separated as a block body and the connection relationship with the structural portion (in this example, the magnet core 6a) which is an unsprung structure portion is also released, these divided bodies 82 and 83 can be easily removed independently of each other. Is possible.
[0040]
Next, the operation of the brake device configured as described above will be described.
[0041]
First, the magnetically levitated vehicle is braked in an ideal state in which the module 5 as the unsprung structure portion, the vehicle body 3 and the rail 2 are substantially free of relative movement in the vertical direction and tilting of the posture. 4 is operated, the brake device 8 in the non-braking state shown in FIG. ₂ Is pressed against one surface of the rail 2. Then, a moving force in the right direction of FIG. 4 acts on the caliper 81 due to this pressing reaction force, and the caliper 81 has a guide pin (sleeve) 84 in the lateral direction of the rail 2 with respect to the magnet core 6a (see FIG. Since it is slidably supported in the left and right direction in FIG. 4, it is moved in the same direction (right side in FIG. 4), and the friction material 12 is moved. ₁ The divided member 82 supporting the friction material 12 serves as a reaction part. ₁ Is pressed against the other surface of the rail 2. Therefore, a pair of friction materials 12 by this ₁ , 12 ₂ A braking force is generated by the rail saddle pressure, and this braking force is transmitted to the module 5 which is the unsprung structure portion of the vehicle including the magnet core 6a via the thrust link 13. At this time, since a force other than the axial direction does not particularly act on the support portion of the guide pin 84, a smooth brake operation is performed.
[0042]
Next, consider the case where the suspension force is lost while the brake is applied and then the levitation force is lost while the brake is applied. In this case, the vehicle descends with respect to the rail 2, and accordingly The module 5 which is the unsprung structure and the integral magnet core 6a as the structural part are also lowered.
[0043]
However, the brake device 8 has the friction material 12 (12 ₁ , 12 ₂ ) Firmly holds the rail 2, the caliper 81 is in a restrained state substantially equal to the state fixed to the rail 2, and is prevented from descending together with the module 8. As described above, the force that the module 5 (magnet core 6a) attempts to lower the brake device 8 and the force that restrains the lowering of the caliper 81 by holding the rail are contrary to each other. Since the cylindrical elastic body 88 fitted between the through hole of the magnet core 6a and the cylindrical bearing member 89 can be compressed in the radial direction, the magnet core 6a is calipered as shown in FIG. The upper part of the cylindrical elastic body 88 is compressed by the amount lowered relative to 81, and the lower part can be extended to absorb this relative shift, and the sliding part and the supporting part Will not cause any damage. Neutral position holding spring 93 ₁ , 93 ₂ Can absorb the relative displacement by the deformation of the coil spring.
[0044]
Further, when a state occurs in which the module 5 (unsprung structure) is inclined with respect to the rail 2 during braking, the cylindrical elastic body 88 is inclined and compressed as shown in FIG. Relative attitude shifts associated with this inclination can be absorbed, and in this respect as well, the sliding portion and the supporting portion are not damaged.
[0045]
As described above, the brake device 8 of the present example moves along the vertical axis (y axis) in FIG. 4 between the magnet core 6a and the caliper 81 and along the axis (z axis) perpendicular to the paper surface. By absorbing the movement by elastic deformation of the cylindrical elastic body 88, the relative displacement (parallel movement) between the magnet core 6a and the caliper 81 can be absorbed, and the horizontal axis (x The movement along the axis) is freely allowed by the sliding of the guide pin 84 and the cylindrical bearing member 89, so that the brake operation due to the caliper floating can be ensured. Further, the relative inclination deviation (rotation) between the magnet core 6a and the caliper 81 around the x axis is restrained because the two guide pins 84 are provided so as to penetrate and fit into the magnet core 6a. The relative tilt shift (rotation) between the magnet core 6 a and the caliper 81 around the y and z axes can be absorbed by the elastic deformation of the cylindrical elastic body 88. Therefore, the amount of elastic deformation of the cylindrical elastic body 88 is designed in consideration of the actual amount that can be generated between the guide pin 84 and the cylindrical bearing member 89 as the positional deviation and the inclination deviation. The occurrence of damage to the brake device in the case illustrated in FIG. 7 can be prevented.
[0046]
【The invention's effect】
As described above, according to the present invention, it is possible to provide a brake device suitable for a suction type vehicle traveling system for a magnetically levitated railway, and its mounting structure, and the following excellent effects can be achieved.
[0047]
(1): It is easy to disassemble, remove, and reassemble the brake device, which is an extremely important safety part for ensuring safe driving control. Regular inspection, maintenance, and replacement of friction materials are also possible. It becomes easy.
[0048]
{Circle around (2)} While disassembling, removing and reassembling the above-mentioned device is facilitated, the strength and rigidity of the brake device and unsprung structure are not reduced.
[0049]
(3): An elastic body that absorbs the relative posture fluctuation between the friction materials while holding the rails is provided, so the brake device adapts to the rail side even if there is shaking on the vehicle side. Therefore, it is possible to maintain the following attitude, and therefore, the relative attitude fluctuation generated between the rail and the rail is suppressed, so that so-called uneven wear can be prevented, in turn, braking failure during braking, and premature wear of the friction material can be prevented. It is done.
[0050]
(4): Since the brake device can maintain the following posture adapted to the rail side as described above, the vibration of the brake device due to irregularity of the rail surface or so-called poor accuracy is attenuated, and the Abnormal vibrations can be prevented from being transmitted to the vehicle side, and riding comfort is not significantly impaired.
[0051]
(5): Even when the vehicle floats and lands in a state where the brake device is substantially fixed to the rail by holding the friction material, the relative displacement in the vertical direction of both can be absorbed by the elastic body. Therefore, an excessive push-up force or push-down force does not act, the rigidity requirement of the unsprung structure of the brake device assembly can be reduced, and the weight increase can be reduced.
