Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a mechanical braking device (brake device) for a magnetic levitation railway and a mounting structure thereof.

[0002]

Brake means in a suction type vehicle running system known as a magnetic levitation railway is obtained by controlling a linear motor which is a thrust means of a vehicle, and is a machine in a broad sense which holds a rail with a pair of friction materials. It is common to use a brake system (a brake system that pushes friction material against the rail) together. This mechanical brake device is different from the brake device in a general railroad or automobile that brakes the rotation of rails and wheels rolling on the road surface, and is connected to the vehicle body by a buffer spring or the like. It has a structure and action peculiar to the magnetic levitation railway in that the ground side rail is held by a friction material provided in a so-called unsprung structure to obtain a braking force action.

As a mechanical brake device used in this magnetically levitated railway, a hydraulically-actuated device using a hydraulic cylinder is generally used. For example, a pair of frictions arranged opposite each other across a rail. Opposed type in which the material is pressed against the rail by the hydraulic pistons arranged on both sides, the hydraulic piston is arranged against the friction material on one side, and on the other side the cylinder member is floatingly moved and pressed by the reaction force of the friction material on one side. Such a caliper floating type is known.

FIGS. 8 to 10 show an example of the floating type braking device, in which 100 is a caliper, which is a hydraulic cylinder portion 10.
1 is arranged on one side of the rail 200, and a mounting bracket 600 fixed to the vehicle side fixing portion (magnet core) 300.
(See FIG. 10) The through holes 102 formed in the caliper 100 slide on the guide pins 301 fixed at both ends, so that the rail 200 slides in the lateral direction (horizontal direction perpendicular to the rail extending direction). It is supported (floatably) freely, and is provided on the opposite side of the rail 200 in a structure in which an arm portion 103 is extended from the hydraulic cylinder portion 101 to form a reaction portion 104. In this example, two pairs of the guide pin 301 and the through-hole 102 are provided so as to prevent the caliper 1 from rotating, and the caliper 1 and the vehicle side are placed in the neutral position when the brake is not applied. Springs 400, 400 for neutral positioning are stretched between the fixed portions 300. Reference numeral 500 denotes a pair of friction members that are arranged to face each other across the rail 200, and one side (hereinafter referred to as “inner side”).
The friction material 500 ₁ is attached to the tip of the hydraulic piston 105, and the opposite friction material 500 ₂ (hereinafter referred to as “outer side”) is attached to the reaction portion 104. Similar to a general attraction type magnetic levitation type vehicle traveling system, the magnetic core 3 of the U-shaped levitation electromagnet is attached to each of the arm portions 200 ₁ and 200 _{2 of the} rail 200 provided in the inverted U shape. 8 are provided so as to face each other, but the position shown in FIG. 8 indicates the portion indicated by the line AA in FIG. 10, so the outside (right side in FIG. 8) is for removing the brake device. Therefore, the notch 306 is formed, and the mounting member 600 forms the mounting portion of the guide pin 301.

In the above structure, a pair of friction materials 500
The thrust link 303 is installed between the bracket 302 provided on the magnet core 300 and the bracket 302 provided on the magnet core 300 as shown in FIG. There is.

The caliper floating type brake device described above is advantageous in that the magnetic levitation railway, in which the reduction of the vehicle weight is important, is smaller and lighter than the opposed type because the hydraulic cylinder is provided on only one side. Is.

[0007]

However, FIGS.
Even in the brake device illustrated in FIG. 10, a problem to be further improved is pointed out.

That is, the mechanical brake device is a very important safety component and device for ensuring safe traveling control, and requires periodic inspection, maintenance and replacement of friction materials. Therefore, it is desired that the disassembly / removal and reassembly of the device can be performed as easily as possible.

However, in the suction type vehicle traveling system of the magnetic levitation railway, the rail 200 laid on the ground side as described above.
That the brake device directly acts on the magnet core 300 to which the brake device is assembled.
The unsprung structure, etc., is the most important part for assembling the levitation magnet (not shown) in the system for magnetically levitation, and the space between the rail and the levitation magnet is 10
From the fact that there is only a narrow gap of about several mm, it is structurally not always easy to disassemble, remove, and reassemble the brake device. Further, 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 by the mounting bolt 307 is removed to remove the brake device. Although it is necessary to remove the caliper 100, which is the main body, in the downward direction, this causes a decrease in mechanical rigidity of the same portion, which is not appropriate in terms of strength of the unsprung structure.

Therefore, it is strongly desired to realize the work of disassembling / removing and reassembling the above-mentioned brake device without causing the deterioration of the strength and rigidity of the important portion.

Further, since the brake device holds the ground-side rail whose posture is immovable as a part of the unsprung structure portion of the traveling vehicle, the brake device follows the sway of the vehicle side. Relative posture change between the frictional material and the rail causes uneven contact between the friction material and the rail during braking, causing so-called uneven wear, causing braking failure during normal braking, and causing early wear of the friction material. There is a problem (see Figure 9).

Further, if vibrations caused by irregularities on the rail surface (irregularities on the surface) and laying accuracy (commonly called "passing accuracy") are transmitted to the vehicle side through the braking device in the braking state without being damped, As an abnormal vibration during braking, there is a problem that the riding comfort on the vehicle side is significantly impaired.

Therefore, there is a demand for a brake device structure and an assembling structure capable of suppressing the relative posture variation and vibration transmission between the rail and the vehicle side as much as possible.

Furthermore, when the brake is actuated, the vehicle floats,
When landing, the brake device (unsprung structure), which is in a substantially fixed relationship with the rail due to the friction material being held, is acted on by the up-and-down force due to the vertical movement of the vehicle, resulting in the unsprung structure. Since the load is concentrated on the brake device assembly part, the rigidity of the same part is required to prevent damage and deformation of the same structural part.
Along with this, the problem of weight increase is brought about. However, reducing the weight of the vehicle is one of the most important issues in a magnetically levitated traveling system.

Therefore, even with respect to such a problem, there is a demand for a brake device structure and an assembly structure capable of preventing damage and suppressing deformation while suppressing an increase in weight as much as possible.

The present invention is capable of solving various problems as described above, and provides a brake device having a structure which can be suitably applied to a suction type vehicle traveling system of a magnetic levitation railway.

[0017]

One of the characteristics of the magnetic levitation railway braking device according to the present invention that achieves the above object is that a rail fixed to the ground side and a magnetic attraction force facing the rail. A levitation electromagnet that levitates the vehicle by action, a brake device that has a pair of friction members that are spaced and opposed to each other on both sides of the rail so that a braking force can be generated by sandwiching the rail, and the levitation electromagnet and the brake device. And a vehicle-side strength structure supporting the vehicle, the brake device presses one of the pair of friction members against the rail by the cylinder device, and moves in the lateral direction of the rail by the pressing reaction force. In a magnetically levitated railway configured to have a caliper that presses the friction material on the rail, the braking device is arranged with the strength structure in between. The caliper is formed by integrating the divided bodies with a detachable fastening means, and the caliper and the strength structure are fitted and slid into a sliding hole formed in one of the caliper and the strength structure. It is said that the guide pin fixed to the other one constitutes a movement guide means for guiding the movement of the caliper in the rail lateral direction.

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 the rail with a minute gap, regardless of whether the rail is an inverted U shape or another shape. In general, and the configuration is a desirable configuration for obtaining an efficient magnetic attraction force, therefore, when the magnet core is used as a strength structure on the vehicle side, the facing state in such a minute gap is This is because it has been understood that a configuration that allows the brake device to be assembled while ensuring the same is desired, and that the above configuration is suitable for satisfying such a request.

With such a structure, the integrated caliper, which may be called the main body of the brake device, can be individually taken out by dividing the above-mentioned divided bodies, which are small elements, by removing the fastening means. Therefore, it can be taken out without being restricted by the structure of the above-mentioned strength structure or without giving a restriction of providing a notch in the structure of the above-mentioned strength structure. More specifically, for example, when the fastening means is constituted by a bolt and a nut and the bolt penetrates the strength structure on the vehicle side, the divided parts of the caliper are separated from each other by removing the nut and pulling out the bolt. Since it can be separated and removed, the work of disassembling, removing, and reassembling the brake device becomes extremely easy.

In the above structure, a hydraulic or pneumatic piston-cylinder is used as the cylinder device that presses one of the friction members of the brake device against the rail, but the present invention is not limited to this.

In the present invention, examples of the strength structure include, but are not limited to, a so-called unsprung frame, a magnet core of a levitation electromagnet, and the like.

Another feature of the present invention is that, in the above-mentioned structure, a sliding hole formed in either one of the caliper and the strength structure constituting the movement guide means, and the fitting hole inserted therein. At least two sets of guide pins are provided, and an elastic body is interposed between the sliding hole and the guide pin sliding portion so as to allow relative parallel movement and relative tilting of both shaft cores. It is in the place where it is composed.

With this structure, the friction material firmly holds the friction material during braking, and thus the caliper is substantially fixed to the rail side. The strength structure such as a vehicle-side magnet core supporting the caliper absorbs relative radial movement and inclination of the caliper due to elastic deformation of the elastic body of the movement guide supporting means interposed between the caliper and the caliper. Since it is buffered, an unreasonable load does not act, and therefore the load on the design strength of the strength structure such as the magnet core is reduced.

Further, the elastic body absorbs and buffers the vibration of the caliper caused by the irregularity of the rail surface, so that the transmission thereof to the vehicle body side is suppressed.

Further, in the present invention, in short, "a sliding hole is formed in either one of the caliper and the strength structure, and on the other hand, a guide pin fitted and inserted into this sliding hole is inserted in either the caliper or the strength structure. `` Fix on the other side '' specifies the configuration, but even if the both ends of the guide pin are fixed to the caliper and the middle part is slid into the sliding hole of the strength structure, on the contrary, the guide pin This is because the object of the present invention can be sufficiently achieved with any of the types in which the intermediate portion of the above is fixed to the strength structure and both ends are slid into the sliding holes of the caliper. Since it can also be used as a fastening means for the caliper split body, the former type of fixing both ends of the guide pin to the caliper is preferably adopted.

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 surface, but in order to minimize sliding resistance, By providing a tubular member that forms the mating surface, the position of the tubular member,
The elastic body is preferably provided as a backing material so that the posture can be changed.

FIG. 4 is a vertical cross-sectional view of the brake device, in which a part of each core is cut away.

In these drawings, reference numeral 81 is a caliper of the brake device, and a pair of divided bodies 82 and 83 arranged on both sides of the caliper 6a sandwiching the magnet core 6a are composed of three sets of bolt members and nut members described below. It is integrated by fastening with fastening means. That is, as shown in FIG. 3, the first and second fastening means in the present example are arranged in parallel at a substantially middle position in the vertical direction of the caliper 81, and the sleeve 84 penetrating the magnet core 6a has both ends thereof described above. By engaging the inner surfaces 82a, 83a of the pair of divided bodies, the approach of the divided bodies 82, 83 is restricted, and the through holes 82b, 8 formed in the divided bodies 82, 83 are controlled.
3b and the bolt member 85 penetrating the sleeve 84 and the nut member 86 screwed to the threaded end portion of the bolt member 85 are fastened, so that the divided bodies 82 and 83 are fastened in a manner to tighten the sleeve 84. The third fastening means is a long nut member 8 sandwiched between the lower ends of the pair of split bodies 82 and 83 extending below the magnet core 6a.
The bolt member 82 inserted through the through holes 82c, 83c formed in the divided bodies 82, 83 into the threaded portions on both sides of 7.
d and 83d are screwed together and fastened.

By these first to third fastening means, the pair of split bodies 82 and 83 are integrated into one caliper 81.
Becomes Reference numeral 83e is a piston that is slidably fitted in the cylinder 83f, and is adapted to press the friction material 12 ₂ against the rail 2 by supplying pressurized air from an air pressure source (not shown) through the supply pipe 83g. .

The characteristic of this embodiment is that the sleeve 84 of the first and second fastening means constructed as described above also serves as a guide pin which is axially movable with respect to the through hole of the magnet core 6a. At the same time, the sleeve (hereinafter, referred to as “guide pin” in consideration of its function) 84 is formed by the magnet core 6
It is configured such that radial movement and axial center tilting are allowed with respect to a.

That is, the above-mentioned magnet core 6a is
A cylindrical elastic body 88 made of, for example, rubber is fitted to the inner peripheral surface 6b of the through hole formed so that the guide pin 84 penetrates,
Further, a short cylindrical bearing member 89 made of a rigid material such as a metal material is fitted to the inner circumference of the cylindrical elastic body 88, and the cylindrical slide bearing member 89 is axially arranged on the outer circumference of the guide pin 84. It is configured to be slidably movable. The tubular elastic body 88 made of rubber 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 through the washer 91 _1, 91 _2, and is retaining secured by a nut 92 _1, 92 ₂ which are screwed into threaded portion formed on the outer periphery of the cylindrical bearing member 89.

Numerals 93 ₁ and 93 ₂ are a pair of neutral position holding springs for holding the caliper 81 at the neutral position when the brake is not applied, and are stretched between the magnet core 6a and the pair of divided bodies 82 and 83. ing.

FIG. 5 is a diagram showing in more detail the structure of the portion for supporting the guide pin (sleeve 84) of the brake device 8 configured as described above. The guide pin 84 and the slide bearing member 89 are slidably engaged with each other. to always maintaining good slidability of the surface protective boot 94 _1, 94 ₂ are bridged as shown to seal these smooth mating surface from the outside air.

In the brake device having the above construction, the split body 8 forming the caliper 81 can be obtained by removing the engagement relationship between the bolts and nuts forming the first to third fastening means.
2,83 are separated as small blocks,
Further, since the connection with the structural portion (the magnet core 6a in this example) which is the portion of the unsprung structure is released, these divided bodies 82 and 83 can be easily removed independently.

Next, the operation of the brake device constructed as above will be described.

First, the magnetic levitation type vehicle has a module 5 which is an unsprung structure portion thereof, a vehicle body 3 and a rail 2.
Suppose that the brake is operated in an ideal state in which relative movement in the vertical direction and tilting of the posture do not substantially occur, the brake device 8 in the non-braking state shown in FIG. The piston 83e causes the friction material 1 to
2 ₂ presses on one side of the rail 2. Then, due to this pressing reaction force, a moving force in the rightward direction in FIG. 4 acts on the caliper 81, and in the caliper 81, the guide pin (sleeve) 84 moves in the lateral direction of the rail 2 with respect to the magnet core 6a ( Since it is slidably supported in the left-right direction in FIG. 4, it is moved in the same direction (right-side direction in FIG. 4), and the split body 82 supporting the friction material 12 ₁ serves as a reaction portion of the friction material 12 ₁ On the other side of the rail 2. Therefore, a braking force is generated by the rail pinching pressure of the pair of friction members 12 ₁ and 12 ₂ by this, and this braking force via the thrust link 13 is the unsprung structure portion of the vehicle including the magnet core 6a. It will be transmitted to 5. At this time, since a force other than the axial direction does not particularly act on the support portion of the guide pin 84, smooth brake operation is performed.

Next, considering the case where the levitation force is lost while the brake is applied and stopped during the ascending run, the vehicle descends with respect to the rail 2 in this case. Therefore, the module 5 having the unsprung structure and the magnet core 6a integrated as a structural part of the module 5 are also lowered.

However, in the brake device 8, since the friction material 12 (12 ₁ , 12 ₂ ) firmly holds the rail 2 in place, the caliper 81 is in a restrained state substantially equal to the state in which it is fixed to the rail 2. , The module 8 is restricted from descending. As described above, the force by which 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 the rail holding against each other act against each other, but in the configuration of this example. Is the through hole of the magnet core 6a and the tubular bearing member 89.
Since the cylindrical elastic body 88 fitted between the two is compressed in the radial direction, as shown in FIG. 6, the magnet core 6a is moved downward relative to the caliper 81. The upper part of the cylindrical elastic body 88 is compressed, and the lower part of the cylindrical elastic body 88 expands to absorb this relative displacement, so that the sliding part and the supporting part are not damaged. Note neutral position holding spring 93 _1, 93 ₂ can absorb the relative displacement due to deformation of the coil spring.

When the module 5 (unsprung structure) tilts with respect to the rail 2 during braking, the cylindrical elastic body 88 is tilted and compressed as shown in FIG. As a result, it is possible to absorb the relative positional deviation due to this inclination, and in this respect as well, the sliding portion and the supporting portion are not damaged.

As described above, the brake device 8 of this example is
The movement between the magnet core 6a and the caliper 81 along the vertical axis (y-axis) in FIG. 4 and the axis (z
By absorbing the movement along the axis by the elastic deformation of the cylindrical elastic body 88, it is possible to absorb the relative displacement (parallel movement) of the magnet core 6a and the caliper 81, and By allowing the guide pin 84 and the tubular bearing member 89 to slide freely along the direction axis (x-axis), the brake operation by the floating of the caliper can be guaranteed. Also above x
Relative inclination deviation (rotation) between the magnet core 6a and the caliper 81 about the axis is restrained because the two guide pins 84 are provided so as to fit through the magnet core 6a, while y, z Relative displacement (rotation) between the magnet core 6a and the caliper 81 about the axis can be absorbed by elastic deformation of the tubular elastic body 88. Therefore, in consideration of the actual amount that may occur between the guide pin 84 and the cylindrical bearing member 89 as the above-mentioned positional deviation and inclination deviation,
By designing the elastically deformable amount of the tubular elastic body 88, it is possible to prevent the occurrence of damage to the brake device in the case described with reference to FIGS. 6 and 7.

[0046]

As described above, according to the present invention,
It is possible to provide a brake device suitable for a suction type vehicle traveling system of a magnetic levitation railway and its mounting structure, and particularly the following excellent effects are exhibited.

It is easy to disassemble, remove, and reassemble the brake device, which is a very important safety component for ensuring safe traveling control, and periodical inspection, maintenance and replacement of friction materials are possible. It will be easy.

: The above-mentioned device can be easily disassembled, removed, and reassembled, and the strength and rigidity of the brake device and the unsprung structure are not deteriorated.

Since the elastic member is provided to absorb the relative posture variation between the friction material holding the rail, the brake device is adapted to the rail side even if the vehicle side shakes. The following postures can be maintained, and therefore relative posture fluctuations with the rails are suppressed, so that so-called uneven wear is prevented, which in turn prevents braking failure during braking, and prevents premature wear of the friction material. To be

Since the brake device can maintain the following posture adapted to the rail side as described above, vibrations of the brake device caused by irregularities on the rail surface and so-called poor passing accuracy are damped, and the braking device is not affected. Abnormal vibration can be suppressed from being transmitted to the vehicle side, and riding comfort is not significantly impaired.

Even if the vehicle is floated or landed in a state where the brake device is in a substantially fixed relationship with the rail due to the friction material being held, the elastic body can absorb the relative positional displacement between the two in the vertical direction. Therefore, an unreasonable push-up force or push-down force does not act, and the rigidity requirement of the unsprung structure of the brake device assembling portion can be reduced, and the increase in weight can be reduced.
